    Abstract The first total synthesis of the alkaloid (-)-haliclonin A is reported. The asymmetric synthesis relied on a novel organocatalytic asymmetric conjugate addition of nitromethane with 3-alkenyl cyclohex-2-enone to set the stereochemistry of the all-carbon quaternary stereogenic center. The synthesis also features a Pd-promoted cyclization to form the 3-azabicyclo[3,3,1]nonane core, a SmI2 -mediated intermolecular reductive coupling of enone with aldehyde to form the requisite secondary chiral alcohol, ring-closing alkene and alkyne metathesis reactions to build the two aza-macrocyclic ring systems, and an unprecedented direct transformation of enol into enone.

    Abstract: ... Affiliated Hospital of Sun Yat-sen University from January 2011 to August 2017. Pre-operative demographic and ...

    Abstract Background: A surgical site infection (SSI) is a major post-operative complication from elective colorectal surgery; however, few studies have focused on evaluating the risk factors for SSI. This study aimed to analyze the relative correlation of medical and environmental factors as well as patient-related factors that contribute to the incidence of all types of SSI.
    Methods: A retrospective search for eligible patients was conducted using the patient database of the Gastrointestinal Surgery Center of the Third Affiliated Hospital of Sun Yat-sen University from January 2011 to August 2017. Pre-operative demographic and surgical data were extracted and recoded according to the study protocol. Univariate and multivariate analyses were performed to clarify factors affecting the incidence of SSI. Propensity analysis was conducted to minimize bias in the demographic characteristics to explore the prophylactic effect of pre-operative administration of oral antibiotics.
    Results: Univariate analysis of the baseline characteristics revealed that younger age (odds ratio [OR]: 0.378; 95% confidence interval [CI]: 0.218-0.657) and pre-operative oral antibiotic use (OR: 0.465; 95% CI: 0.255-0.850) were protective factors, while pre-operative anemia (OR: 4.591; 95% CI: 2.567-8.211), neoadjuvant chemotherapy history (OR: 2.398; 95% CI: 1.094-5.256), and longer surgical duration (OR: 2.393; 95% CI: 1.349-4.246; P = 0.002) were identified as risk factors for SSI. Multivariate analysis indicated that age (P = 0.003), surgical duration (P = 0.001), and pre-operative oral antibiotic use (P < 0.001) were independent factors that affect the incidence of SSI. Furthermore, a propensity-matched analysis confirmed the protective effect of oral antibiotic use, with a 1-day course of oral antibiotic producing a similar effect to a 3-day course.
    Conclusions: Age, surgical duration, and pre-operative oral antibiotic use were associated with the incidence of SSI. However, pre-operative oral antibiotic use was the only controllable factor. From the results of our study, pre-operative oral antibiotic use is recommended before elective colorectal surgery and a 1-day course is enough to provide the protective effect.

    Abstract Wenya Pei,1 Jingchun Zeng,2 Liming Lu,3 Guohua Lin,2 Jingwen Ruan11Department of Acupuncture, the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, Guangdong, People’s Republic of China; 2Department of Acupuncture, The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China; 3Clinical Medical Center, South China Research Center for Acupuncture and Moxibustion, Medical College of Acu-Moxi and Rehabilitation, Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, ChinaBackground: Postherpetic neuralgia (PHN) refers to pain which remains after the healing of rashes from herpes zoster. Previous literatures have shown that acupuncture has potential benefits for PHN, but evidence remains lacking. Thus, we have performed a systematic review and meta-analysis to identify the effectiveness of acupuncture in the treatment of PHN.Methods: Six databases were searched for randomized controlled trials (RCTs) to assess the effects of acupuncture on PHN. After selecting the studies, extracting the data, and assessing study quality, meta-analysis was performed on several of the studies with RevMan 5.3. The GRADE (Grading of Recommendations Assessment Development and Evaluation) system was used to assess the overall quality of the evidence.Results: Acupuncture helps relieve pain intensity (standardized mean difference [SMD]: −1.78, 95% confidence interval [CI]: −2.36 to −1.21). For other intervention types, electroacupuncture (SMD: −1.28, 95% CI: −2.51 to −0.05), fire needle (SMD: −2.23, 95% CI: −2.62 to −1.84), bloodletting and cupping (SMD: −2.46, 95% CI: −2.95 to −1.97) have better effects on pain intensity relief. To date, no study has reported on the onset of pain relief time. The Hamilton Anxiety Scale score (SMD: −18.94, 95% CI: −37.37 to −0.52) was lower for the acupuncture group than for the control group. It was also found that acupuncture can improve quality of life (QOL) (SMD: 3.78, 95% CI: 2.50 to 5.06). The quality of evidence for acupuncture for PHN ...

    Abstract The Taishan Antineutrino Observatory (TAO, also known as JUNO-TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). A ton-level liquid scintillator detector will be placed at about 30 m from a core of the Taishan Nuclear Power Plant. The reactor antineutrino spectrum will be measured with sub-percent energy resolution, to provide a reference spectrum for future reactor neutrino experiments, and to provide a benchmark measurement to test nuclear databases. A spherical acrylic vessel containing 2.8 ton gadolinium-doped liquid scintillator will be viewed by 10 m^2 Silicon Photomultipliers (SiPMs) of >50% photon detection efficiency with almost full coverage. The photoelectron yield is about 4500 per MeV, an order higher than any existing large-scale liquid scintillator detectors. The detector operates at -50 degree C to lower the dark noise of SiPMs to an acceptable level. The detector will measure about 2000 reactor antineutrinos per day, and is designed to be well shielded from cosmogenic backgrounds and ambient radioactivities to have about 10% background-to-signal ratio. The experiment is expected to start operation in 2022.

    Abstract: ... and pathologic data of 52 HCC patients, received resection in Cancer Center of Sun Yat-sen University ...

    Abstract Background & objective: The helical double-phase CT scan imaging features of hepatocellular carcinoma (HCC) overlap those of other hepatic lesions. This study was to investigate the helical double-phase CT scan imaging features of HCC to improve diagnosis accuracy.
    Methods: Double-phase CT data and pathologic data of 52 HCC patients, received resection in Cancer Center of Sun Yat-sen University from Dec. 2000 to Dec. 2002, were analyzed. The double-phase CT features of HCC lesions were summarized. The pathology of false-positive lesions was analyzed.
    Results: CT scan showed 56 lesions in the 52 patients: 51 were cancer lesions, including 49 HCC lesions and 2 mixed lesions of HCC and cholangioma, 5 were false-positive lesions. Arterial phase of these HCC lesions showed obvious heterogeneous enhancement, and the portal vein phase showed heterogeneous low dense. Necrosis was seen in all massive lesions, but was seldom seen in nodular and small lesions. Most lesions had clear borders and amicula. The pathologic diagnoses of the 5 false-positive lesions were hepatic cirrhosis with hepatocellular nodular hyperplasia, regenerative nodule, hepatic cirrhosis, bile duct calculus companied with inflammatory reaction, and fibrosis hyperplasia.
    Conclusions: Helical double-phase CT scan can be used to diagnose typical HCC lesions. There are no obvious differences in helical double-phase CT scan between HCC lesions and false-positive lesions. The diagnosis of HCC must be based on clinical information, follow-up or biopsy.

    Abstract Background & objective: Focal nodular hyperplasia (FNH) is a rare hepatic neoplastic lesion. This study was to evaluate the typical and atypical features of FNH of the liver on helical computed tomography (CT) images to improve the diagnosis accuracy.
    Methods: Helical CT images of 32 patients with 37 lesions were reviewed in Cancer Center, Sun Yat-sen University retrospectively, who were confirmed as FNH by histopathologic or clinic examinations. The number, size, margin status, density, enhancing type, presence of a center scar, and presence of a pseudocapsule of FNH lesions were analyzed.
    Results: The largest diameters of 14 lesions were < or = 3 cm, of 23 lesions were > 3 cm; 20 lesions were subcapsular; pseudocapsule was presented in 7 lesions with the largest diameters of > 3 cm; 22 lesions had center scars, among them, the largest diameters of 20 lesions was > 3 cm. All lesions were hyperattenuated to the liver in hepatic arterial phase; 31 lesions were enhanced homogeneously in hepatic arterial phase; abnormally thickened vessels were presented at the border of 17 lesions.
    Conclusions: Typical helical CT features of FNH include homogeneous enhancement in hepatic arterial phase, presence of central scar, and delayed enhancement. Atypical helical CT features of FNH include heterogeneous enhancement in hepatic arterial phase, absence of central scar, and presence of pseudocapsule. The various CT features are related to the pathologic type and the largest diameter of the lesion.
