Deep vein thrombosis(DVT)is a common complication after surgery for lower limb fracture.It has the features of high morbidity,high disability rate and high mortality.At present,the measures for clinical prevention and treatment of post-operative DVT in lower limb fracture mainly include perioperative nursing,intervention with medical auxiliary instruments,western medicine prevention and treatment,traditional Chinese medicine(TCM)intervention,and patients'self-cooperation.The patients'self-cooperation is the basis for the smooth implementation of other measures for prevention and treatment,and the patients'active cooperation is the premise of achieving the efficacy of prevention and treatment.Perioperative nursing is helpful for the patients to understand the risk factors of postoperative DVT and the possible risks after the occurrence of DVT,guides the patients to choose the food,assists the patients to do postoperative exercises,improves the level of patients'hemorheological indexes,and reduce the incidence of postoperative DVT.Medical devices are helpful for assisting patients to do postoperative rehabilitation exercises,improving the levels of hemodynamic indicators,promoting patients'rehabilitation and reducing the incidence of postoperative DVT.Western medicines such as low molecular weight heparin,Rivaroxaban,Enoxaparin and other anticoagulant drugs can reduce the aggregation of coagulation factors and blood viscosity,and reduce the incidence of postoperative DVT.TCM interventions mainly include oral administration of Chinese medicine and external treatment such as acupuncture,moxibustion and massage.Oral administration of Chinese medicine is helpful for improving blood flow status.Acupuncture,moxibustion and massage are beneficial to the activation of the function of zang-fu organs,and can stimulate the healthy qi to improve the qi-blood state of the whole body.Each method of prevention and treatment has its advantages and disadvantages.In clinical application,reasonable prevention and treatment methods should be selected according to the specific conditions and individual conditions of the patients.TCM intervention of DVT can be performed in patients with lower limb fracture before and after surgery,and has the advantages of low cost and definite efficacy,which is worthy of continuous research and inheritance and innovation.

Objective: To analyze the characteristics of human papillomavirus (HPV) infection and the distribution of HPV subtypes in Shijiazhuang, Hebei Province, and to explore the application evaluation of multiple PCR capillary electrophoresis fragment analysis for HPV typing test. Methods: A population-based cross-sectional study was conducted among 434 women (age range 17 to 74 years old, 260 patients and 174 physical examinations) included from May to August 2022 in Hebei General Hospital. HPV typing was detected by multiple PCR-capillary electrophoresis fragment analysis. Using the multiple fluorescence quantitative PCR kit as a reference, Chi-square test was used to analyze the diagnostic effect of multiple PCR-capillary electrophoresis fragment analysis, and the consistency was analyzed by Kappa value. Results: The total HPV infection rate was 45.85%(199/434), including 35.48% (154/434) of high-risk HPV (HR-HPV), 3.92% (17/434) of low-risk HPV (LR-HPV), 6.45% (28/434) of HR-HPV and LR-HPV mixed infection, 27.88% (121/434) of single type HPV and 17.97% (78/434) of multi type HPV. HPV52 (9.68%, 42/434), HPV16 (6.91%, 30/434), and HPV58 (6.91%, 30/434) are common HPV subtypes. The positive rate of physical examination was 45.40% (79/174), which was slightly lower than that of patients 46.15% (120/260), there was no significant difference (χ²=0.024,P>0.05). The highest infection rate in the 17-30 age group was 54.76% (46/84), and there was no statistical difference among the age groups(χ²=4.123,P>0.05). The sensitivity and specificity of multiplex PCR capillary electrophoresis fragment analysis were 92.96% and 94.04%, respectively, and Kappa value was 0.870, with the multiplex fluorescent quantitative PCR as the reference. Conclusion: HPV infection may appear younger, and the positive rate of HR-HPV infection is the highest, with HPV52, 16, 58 as the main infection subtypes. The detection results of multiplex PCR capillary electrophoresis fragment analysis method are highly consistent with those of multiplex fluorescent quantitative PCR method, which is suitable for HPV DNA typing.

Objective: To analyze the immunological characteristics and antibody changes of patients infected with the Omicron BA.1 and evaluate the possibility of secondary infection. Methods: A total of 104 patients infected with Omicron BA.1 in the Jinnan District of Tianjin from January 8 to February 2, 2022, were included in the study. The control group and case group were matched 1∶1 based on age, sex and vaccination status. Serum was collected from the case group and control group at 3, 6 and 9 months after infection. The serum levels of interleukin4 (IL-4), IL-5 and interferon-gamma (IFN-γ), as well as the positive rates of IgG, IgG1 and IgG2, were detected by ELISA. Results: The highest concentration of IFN-γ in the case group at 6 months after infection was 145.4 pg/ml, followed by a decrease in concentration. The concentrations of IL-4 and IL-5 began to decrease at 6 months after infection (all P<0.001). There was no significant difference in the IgG2 positive rate between the case group and the control group at 6 months after BA.1 infection. However, at 9 months, there was a significant decrease compared to the control group (P=0.003). The ratio of IFN-γ/IL4 at 3 months after infection in the case group was lower than that in the control group (P<0.001). There was no significant difference in the ratio between the case group and the control group at 9 months after infection. Conclusion: The cellular immune function has been impaired at 3 months after infection with BA.1, and the specific cellular immune and humoral immune functions decrease significantly after 6 months, and the risk of secondary infection increases.

ObjectiveTo explore the molecular mechanism of Yishen Tongluo prescription in inhibiting the apoptosis of glomerular podocytes in rats with membranous nephropathy （MN） based on the miR-514a-5p/tumor necrosis factor superfamily member 15 （TNFSF15） signaling pathway. MethodEighty SD rats were pre-immunized and injected with cationized bovine serum albumin （C-BSA） into the tail vein for inducing MN， and the successfully modeled MN rats were randomly divided into the model group， high-， middle-， and low-dose （26.44， 13.22， 6.61 g·kg^-1） Yishen Tongluo prescription groups， and benazepril （10 mg·kg^-1） group， with 10 rats in each group， and another 20 healthy rats were classified into the normal group. Rats in each group were gavaged with the corresponding drugs， once a day， for four successive weeks. After the administration， the 24-hour urine total protein （UTP） level， serum total cholesterol （TC）， triglyceride （TG）， albumin （ALB）， creatinine （SCr）， and urea nitrogen （BUN） levels were measured. The miR-514a-5p and TNFSF15 mRNA expression levels in the rat kidney tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， and the expression levels of podocyte marker proteins Nephrin， Podocin， Podocalyxin， Synaptopodin， TNFSF15， and podocyte apoptosis-related proteins B lymphocytoma-2 （Bcl-2）-related X protein （Bax）， Bcl-2-associated death promoter （BAD） protein， and B-cell lymphoma-extra large （Bcl-XL） by immunohistochemistry （IHC）. Western blot was used to detect the expression levels of TNFSF15， Bax， BAD， Bcl-2， and BCL-XL in the rat kidney tissue. The apoptosis rate of rat kidney tissue was measured using the in situ end labeling method （Tunnel）. ResultCompared with the normal group， the level of miR-514a-5p in the kidney tissue was significantly reduced （P<0.05）， and the TNFSF15 mRNA expression was significantly increased （P<0.05）. The expression levels of podocyte marker proteins Nephrin， Podocin， Podocalyxin， and Synaptopodin were down-regulated （P<0.05）. The protein expression levels of TNFSF15， Bax， and BAD were increased （P<0.05）， whereas the Bcl-2 and Bcl-XL protein expression levels were decreased （P<0.05）. The number of apoptotic cells diminished significantly （P<0.05）. Compared with the model group， the level of miR-514a-5p in the kidney tissue was significantly increased （P<0.05）， while the level of TNFSF15 mRNA was significantly decreased （P<0.05）. The expression levels of podocyte marker proteins Nephrin， Podocin， podocalyxin， and Synaptopodin were up-regulated （P<0.05）， whereas the TNFSF15， Bax， and BAD protein expression levels were down-regulated （P<0.05）. Bcl-2 and Bcl-XL protein expression levels rose （P<0.05）. The number of apoptotic cells significantly decreased （P<0.05）. ConclusionYishen Tongluo prescription reduces the apoptosis of rat kidney podocytes and alleviates the kidney injury of MN rats through the miR-514a-5p/TNFSF15 signaling pathway.

Six new (1-6) and seven known depsidones (7-13) were isolated from the culture of an ant (Monomorium chinensis)-derived fungus Spiromastix sp. MY-1. Their structures were elucidated by extensive spectroscopic analysis including high resolution MS, 1D and 2D NMR data. The new bromide depsidones were obtained through supplementing potassium bromide in the fermentation medium of Spiromastix sp. MY-1. All isolated compounds showed various bioactivities against the tested phytopathogenic bacteria. Particularly, new bromide compound 4, named spiromastixone S, exhibited the strongest activity against Xanthomonas oryzae pv. oryzae with a MIC value of 5.2 μmol·^-1.

The current clinical evidence and underlying mechanisms of acupuncture and moxibustion in the treatment of irritable bowel syndrome (IBS) were summarized, so as to better optimize clinical treatment. The relevant articles of acupuncture and moxibustion in the treatment of IBS in recent years were retrieved and summarized. We found that the clinical efficacy of acupuncture and moxibustion in the treatment of IBS was relatively reliable. However, the mutual relationships among various mechanisms of action such as abnormal gastrointestinal motility, high visceral sensitivity, intestinal microenvironment disorders, and abnormal intestinal-brain interactions need to be further explored. The authors believe that in-depth explorations of the bidirectional regulation of "gut-brain axis", the law of changes in the abundance and diversity of intestinal flora, and the establishment of a more ideal animal model of TCM syndrome differentiation are useful ideas for subsequent research.
