    Abstract Occupational pneumoconiosis in the coal industry is an occupational disease that seriously endangers coal miners' health. Early diagnosis and prevention techniques are significant in controlling its incidence rate and reducing its harm. This article takes the patent data related to the early diagnosis and prevention of occupational pneumoconiosis in the coal industry, published from 1985 to 2021, as the research object. It uses tools such as the Derwent Data Analyzer (DDA) software, the Patyee Database, and the PatSnap Database to analyze the technological development trend and characteristics in this field from aspects of growth trend, primary patent holders, IPC classification layout, value, and research and development hotspots. The results show that the number of patent applications in this field indicates a rapid growth trend, mainly in the hands of Shandong Energy Group Co. Ltd., Shandong University of Science and Technology, China University of Mining and Technology, and other institutions or enterprises. Patent technology mainly involves spray dust reduction, dust removal fans, dust masks, and other aspects with high patent value and innovation ability. This article provides a new perspective and reference for preventing, diagnosing, and treating occupational pneumoconiosis in the coal industry.

    Abstract The hind wings of beetles are deployable and play an essential role in flight. In the Asian ladybird Harmonia axyridis (Coleoptera: Coccinellidae), the pterostigma (pst) is found in the middle of the hind wing instead of at the tip of the hind wing. This paper investigates the effect of the pst on the vibrational characteristics during the flight of H. axyridis. Based on cross sections of the pst and veins as well as the morphology and nanomechanical properties of the hind wing, including the wing membrane and veins, three three-dimensional coupling models, Models I-III, of hind wings with/without pst structures and veins with varying or uniform reduced moduli are established. Modal analysis results for these three models show that the vibrational characteristics and deformation tendencies change the flight performance of the hind wing models with pst structures compared with that of the other models. The results in this paper reveal that the pst structure has an important influence on vibrational characteristics and deformation tendencies and, hence, on flight performance; the relationships between the body mass and the area of the hind wing, which have significant implications for the design of biomimetic deployable wing structures for micro air vehicles (MAVs), are also analyzed.

    Abstract Summary: SFT is a rare lesion of the sinonasal cavity. We retrospectively reviewed 5 patients with histopathologically proved sinonasal SFTs to determine their CT and MR imaging features. All patients underwent paranasal sinus CT and MR imaging. Four SFTs occurred in the nasal cavity, and 1, in the maxillary sinus. All SFTs had well-defined margins, and the mean maximum diameter was 55 mm. On nonenhanced CT, 5 SFTs appeared homogeneously isoattenuating to gray matter. The most common manifestations of bony involvement were bony remodeling and thinning. On MR imaging, 5 SFTs were isointense to gray matter on T1-weighted images, and the lesions were isointense in 3 and hypointense in 2 patients on T2-weighted images. The lesions showed heterogeneously marked enhancement on postenhanced MR images. Four patients underwent dynamic contrast-enhanced MR imaging, and the TICs showed a washout pattern. A familiarity with the imaging findings of sinonasal SFT may help to diagnose this entity.

    Abstract Eight cholangio-thoracic fistula patients were seen from 1981 to 1987 in our hospital. The clinical features of the cases were classified into four types, i.e. bronchobiliary fistula (BBF, 3 cases), bronchopleurobiliary fistula (BPBF, 2 cases), pleurobiliary fistula (PBF, 2 cases) and pericardiobiliary fistula (PCBF, 1 case). In addition to a history of cholangitis or cholelithiasis and continuous or intermittent secondary biliary tract infection, the principle manifestations of BBF included: acute, subacute or chronic biliary empyema; biliary pneumonia or biliary lung abscess; and biliptysis. The empyema perforating into trachea, bronchus, pericardium and large vessels in the thoracic cavity may result in serious consequences. Asphyxiation, pericardial tamponade and abrupt massive intrathoracic hemorrhage may also be fatal. It is often difficult to locate the fistula by bronchoscopy, however the bile found in the respiratory tract may suggest BBF. Surgical management of BBF and PCBF are discussed.

    Abstract The cellular DNA contents of 139 bladder irrigations from 52 cases of bladder tumors were determined by flow cytometry. The results were compared with those of pathological grading and exfoliative cytology. It is suggested that cytological results were less accurate than DNA contents. High aneuploid DNA contents in tumor cells were marked by low grade and deep penetration of the bladder tumor. Total cystectomy was needed for bladder tumor with high aneuploid DNA, and partial cystectomy and TURBT for that tumor showed high recurrence with instillation of BCG. The results showed that DNA content of tumor is correlated with the nuclear grade, especially in poorly differentiated neoplasms, but flow cytometry can not replace cystoscopy examination.

    Abstract By means of Langendorff method and standard microelectrode techniques the effects of Ciwujia on reperfusion induced arrhythmias and action potential alterations were studied in isolated rat heart with transient coronary occlusion. Inclusion of Ciwujia extract (equivalent to 1.2 and 2.4 mg crude drug/ml) was found helpful in reducing reperfusion induced ventricular fibrillation and ventricular tachycardia. Associated with this reduction in rhythm disturbances was an increase in the total duration of normal sinus rhythm during the 3 min reperfusion period. With the administration of Ciwujia the number of cells with abnormal action potential configurations was significantly reduced. This confirms that Ciwujia can protect myocardium from electrophysiological abnormalities, and therefore reduces the incidence of malignant arrhythmias.
