Objective: To investigate the distribution of HIV-1 genetic subtypes and pretreatment drug resistance (PDR) among men who have sex with men (MSM) from 19 cities of 6 provinces in China. Methods: From April to November 2019, 574 plasma samples of ART-naive HIV-1 infected MSM were collected from 19 cities in Hebei, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong provinces, total ribonucleic acid (RNA) was extracted and amplified the HIV-1 pol gene region by nested polymerase chain reaction (PCR) after reverse transcription. Then sequences were used to construct a phylogenetic tree to determine genetic subtypes and submitted to the Stanford drug resistance database for drug resistance analysis. Results: A total of 479 samples were successfully amplified by PCR. The HIV-1 genetic subtypes included CRF01_AE, CRF07_BC, B, CRF55_01B, CRF59_01B, CRF65_cpx, CRF103_01B, CRF67_01B, CRF68_01B and unrecognized subtype, which accounted for 43.4%, 36.3%, 6.3%, 5.9%, 0.8%, 0.8%, 0.4%, 0.4%, 0.2% and 5.5%, respectively. The distribution of genetic subtypes among provinces is statistically different (χ2=44.141, P<0.001). The overall PDR rate was 4.6% (22/479), the drug resistance rate of non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, and protease inhibitors were 3.5% (17/479), 0.8% (4/479) and 0.2% (1/479), respectively. The PDR rate of recent infections was significantly higher than that of long-term infections (χ2=4.634, P=0.031). Conclusions: The HIV-1 genetic subtypes among MSM infected with HIV-1 from 19 cities of 6 provinces in China are diverse, and the distribution of subtypes is different among provinces. The overall PDR rate is low, while the PDR rate of recent infections was significantly higher than that of long-term infections, suggesting the surveillance of PDR in recent infections should be strengthened.

Predictive role of interleukin-6 and CAT score in mechanical ventilation in patients with chronic obstructive pulmonary disease at the acute exacerbation stage in the emergency department / 世界急诊医学杂志（英文）

@#BACKGROUND: The study aimed to evaluate the predictive role of interleukin-6 (IL-6) and chronic obstructive pulmonary disease (COPD) assessment test (CAT) score in mechanical ventilation (MV) in COPD patients at the acute exacerbation stage in the emergency department (ED). METHODS: For a one-year period, among adult patients in the ED who met the criteria of acute exacerbation of COPD, 158 who received MV within 48 hours after admission were compared to 294 who didn't require MV within the same period after admission. IL-6 level and CAT score were compared between the two groups. The predicted value of IL-6 and CAT score was assessed by logistic regression analysis and a receiver operating characteristic (ROC) curve. RESULTS: The IL-6 and CAT scores in the 158 MV patients were much higher than those without. IL-6 and CAT scores were independent predictors of MV within 48 hours using logistic regression analysis (IL-6: odds ratio [OR] 1.053, 95% confidence interval [CI] 1.039–1.067, P<0.001; CAT score: OR 1.122, 95% CI 1.086–1.159, P<0.001). The combination of IL-6 and CAT scores (area under ROC curve [AUC] 0.826, 95% CI 0.786–0.866, P<0.001) improved the accuracy of predicting MV within 48 hours when compared with IL-6 (AUC 0.752, 95% CI 0.703–0.800, P<0.001) and CAT scores alone (AUC 0.739, 95% CI 0.692–0.786, P<0.001). The sensitivity and specificity were 69.6%, 74.1%, 75.32% and 63.6%, respectively. CONCLUSION: The combined of IL-6 and CAT scores is useful for evaluating the risk of COPD patients at acute exacerbation in ED, and can provide a predictive value for MV or not within 48 hours.

Construction and application of effect-related near-infrared spectroscopy for traditional Chinese medicines — Exemplification by rhubarb dispensing granules / 药学学报

Consistency in quality of traditional Chinese medicine granules is an important factor to ensure reproducible clinical efficacy. In this study rhubarb dispensing granules were utilized to construct an efficacious near-infrared spectroscopy (eNIRS) assay by combining NIRS and biopotency. A NIR method for assaying rhubarb dispensing particles was established, and information on different batches was collected. The diarrhea-inducing biopotency of rhubarb dispensing granules was determined based on a constipation model induced by diphenoxylate in mice. The animal protocol was approved by the Animal Ethic Committee​ of 302 Hospital of Chinese PLA People's Liberation Army (ID: IACUC-2019-0010). Ten anthraquinones were determined in rhubarb dispensing granules by UPLC. The correlation between NIR and biopotency was analyzed and five characteristic bands that correlated highly with bioactivity were identified, including 4 011-4 390, 4 859-5 461, 7 012-7 493, 10 992-11 312 and 11 871-12 489 cm-1. There were some differences in the main bands of different chemical constituents. In summary, five active bands based on NIRS were identified and found to be able to achieve rapid on-line detection of rhubarb dispensing granule quality. This research model may also provide reference for quality control of other Chinese medicine dispensing granules.

Photosynthetic characteristics and active ingredients differences of Asarum heterotropoides var. mandshuricum under different light irradiance / 中国中药杂志

Chlorophyll content,leaf mass to per area,net photosynthetic rate and bioactive ingredients of Asarum heterotropoides var. mandshuricum,a skiophyte grown in four levels of solar irradiance were measured and analyzed in order to investigate the response of photosynthetic capability to light irradiance and other environmental factors. It suggested that the leaf mass to per area of plant was greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in the decrease of leaf mass to per area at every phenological stage. At expanding leaf stage,the rate of Chla and Chlb was 3. 11 when A. heterotropoides var. mandshuricum grew in full light irradiance which is similar to the rate of heliophytes,however,the rate of Chla and Chlb was below to 3. 0 when they grew in shading environment. The content of Chla,Chlb and Chl( a+b) was the greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in its decreasing remarkably( P<0. 05). The rate of Chla and Chlb decreased but the content of Chla,Chlb and Chl( a+b) increased gradually with continued shading. The maximum value of photosynthetically active radiation appeared at 10: 00-12: 00 am in a day. The maximum value of net photosynthetic rate appeared at 8: 30-9: 00 am and the minimum value appeared at 14: 00-14: 30 pm at each phenological stage if plants grew in full sunlight. However,when plants grew in shading,the maximum value of net photosynthetic rate appeared at about 10: 30 am and the minimum value appeared at 12: 20-12: 50 pm at each phenological stage. At expanding leaf stage and flowering stage,the average of net photosynthetic rate of leaves in full sunlight was remarkably higher than those in shading and it decreased greatly with decreasing of irradiance gradually( P < 0. 05). However,at fruiting stage,the average of net photosynthetic rate of leaves in full sunlight was lower than those in 50% and 28% full sunlight but higher than those in 12% full sunlight. All photosynthetic diurnal variation parameters of plants measured in four kinds of different irradiance at three stages were used in correlation analysis. The results suggested that no significant correlation was observed between net photosynthetic rate and photosynthetically active radiation,and significant negative correlation was observed between net photosynthetic rate and environmental temperature as well as vapor pressure deficit expect for 12% full sunlight. Positive correlation was observed between net photosynthestic rate and relative humidity expect for 12% full sunlight. Significant positive correlation was observed between net photosynthetic rate and stomatal conductance in the four light treatments. Only,in 12% full sunlight,the net photosynthetic rate was significantly related to photosynthetically active radiation rather than related to environmental temperature,vapor pressure deficit and relative humidity. In each light treatment,a significant positive correlation was observed between environmental temperature and vapor pressure deficit,relative humidity as well as stomatal conductance. Volatile oil content was 1. 46%,2. 16%,1. 56%,1. 30% respectively. ethanol extracts was 23. 44%,22. 45%,22. 18%,21. 12% respectively. Asarinin content was 0. 281%,0. 291%,0. 279% and 0. 252% respectively. The characteristic components of Asarum volatile oil of plant in different light treatments did not change significantly among different groups.

Introduction to Professor Ma Guiqin's experience in treatment of occupational pneumoconiosis / 中国中药杂志

Occupational pneumoconiosis refers to a group of occupational pulmonary diseases,which is mainly characterized by diffuse fibrosis of lung tissue caused by inhalation of different pathogenic productive dust and retention in the lungs during occupational activities for a long period of time. According to the classification and catalogue of occupational diseases in China,it is mainly classified into 12 categories,such as silicosis,coal worker's pneumoconiosis,asbestos lung. At present,it is the most serious and most common occupational disease in China. The pathogenesis of pneumoconiosis is not clear,and there is still no effective therapy. In the past three years,it is found that traditional Chinese medicine is effective in the treatment of pneumoconiosis. Through collection of medical records,the regularity of the prescriptions used in the treatment of pneumoconiosis were analyzed and summarized. According to the traditional Chinese medicine theory,the clinical characteristics of recurrent cough,phlegm and asthma in patients with pneumoconiosis could be included in the categories of cough,wheezing,lung distension. Professor Ma Guiqin believes that the basic pathogenesis of pneumoconiosis is depression of the atmosphere,deficiency of the kidney,internal obstruction of phlegm,and adverse cardinality. According to its pathogenesis,the commonly used prescriptions,namely Shengxian Decoction,Jinshui Liujun Jian,Xiaochaihu Decoction,Sini Powder,Guomin Jian and syndrome differentiation-based modified medicines were expounded. In addition, " throat is the gateway to the lung and stomach",Professor Ma also believes that the prevention of pneumoconiosis should start with the throat,so as to curb the exacerbation or recurrence of the disease. Through clinical observation,if traditional Chinese medicine is properly used,and pathogenesis and syndrome differentiation-based treatment is provided,traditional Chinese medicine can relieve the clinical symptoms,and improve the exercise tolerance and the quality of life of patients with pneumoconiosis.

A rapid and useful method for gender identification of grey red-backed voles / 中国比较医学杂志

Objective Grey red-backed voles (Myodes rufocanus) are agile, fierce and hard to catch, thus, it is difficult to judge their gender by external appearance, especially for the juvenile voles. Therefore, it may cause difficulties to their allocation and later breeding in laboratories. The aim of this paper is to establish a rapid, simple and accurate method for gender identification of grey red-backed voles. Methods Fresh hair follicles were taken from 6 adult male voles, 3 adult females and 14 4-week-old juvenile voles, 5 male and 5 female 9-week-old Wistar rats, and 5 male and 3 female 6-week-old BALB/c mice. The genomic DNA was extracted using Chelex-100 resin and the zinc-finger Y/X gene (ZFY/ZFX) and the gene of sex-determining region of the Y (SRY) chromosome were amplified by PCR, and a double PCR amplification method was established. Results The ZFY/ZFX gene and SRY gene were simultaneously amplified from the male voles, while only the ZFY/ZFX gene was amplified from the females. The gender of all 23 voles, 10 Wistar rats and 8 BALB/c mice were correctly identified with this method, and the PCR results were consistent with the phenotypic and autopsy results. Conclusions Using fresh hair follicles as experimental materials for gender identification of grey redbacked voles can alleviate shock and damage to the animals. The established double PCR amplification method is accurate, simple, rapid, and deserves to be used for gender identification of grey red-backed voles.

In the 12th month, the rates of two groups' patients with CD4 successfully recovered (reached 719 cells/μL) were 12.50% and 39.13%. In the 18th month, the rates were 13.75% and 38.71%. The median time of patients with CD4 first successfully recovered to 719 cells/μL was 7.2 month s in observation group, while the median time of control group was 20.4 months, which was longer than observation group (P<0.05) . A total of 375 patients were tested viral load, and the successful suppression rate of viral load was 97.33%. The rates of observation and control group were 96.34% and 97.50% (P>0.05) . Conclusion The rates of viral successful suppression were similar between baseline CD4 counts ≥500 cells/μL group and<500 cells/μL group among MSM HAART patients. Recovery time in baseline CD4 counts ≥500 cells/μL group was shorter than baseline CD4 counts<500 cells/μL group.

An analysis on HIV rapid test demanding among commercial sex workers / 预防医学

Objective To learn the awareness and related factors of HIV rapid test among commercial sex workers(CSWs)in order to improve the HIV rapid test service. Methods The cross-sectional survey was conducted among CSWs in WenzhouCity and Quzhou City which were divided into high-grade, middle-grade and low-grade. Face to face questionnaire surveywas conducted in the research investigation. The investigation content includes social demographic characteristics, rapiddetection of desire, sexual behavior and HIV testing services. EpiData 3.0 database was used for data entry. Statisticalsoftware SPSS21.0 was used in chi-square and logistic regression analysis of multiple factors. Results A total of 401 CSWswere observed, including 136 people in high-grade, 182 people in middle-grade and 83 people in low-grade. Twohundred and two people and 200 people were investigated respectively in Wenzhou and Quzhou City. The rate of willing toaccept the rapid HIV testing was 56.36%(226) . Analysis by logistic analysis, 30 years old of above(OR=3.312, 95%CI:1.427-7.691), commercial sexual behavior without using condom or casual usage in last 6 month(OR=4.560, 95%CI:2.348-8.855), more than 10 commercial sexual partners(OR=8.767, 95%CI: 2.993-25.677), and having HIV rapidtesting in last year(OR=7.784, 95%CI: 3.108-19.496) were influencing factors for willing to accept HIV rapid testing.Conclusion In CSW HIV/AIDS intervention, adult, few numbers of sexual partners need to be focused. Improving HIVrapid test service, condom using service, and promoting risk sexual awareness may improve the HIV rapid test acceptancewillingness and behavior.

HPLC fingerprint of Xuanbo Shuangsheng Granule / 复旦学报（医学版）

Objective To establish the HPLC fingerprint of Xuanbo Shuangsheng Granule for its quality control.Methods The components were separated on an Agilent TC-C18 column (150 mm ×4.6 mm,5 μm) at 25 ℃,with a gradient elution in 0-60 min at the flow rate of 1 mL/min using 0.2％ acetic acid aqueous solution and methanol as the mobile phase.The detection wavelength was 278 nm.By detecting 11 batches of Xuanbo Shuangsheng Granule,the HPLC fingerprint was established using Similarity Evaluation System for Chromatographic Fingerprint of TCMs (Version 2004A)and the common peaks were analyzed and identified in raw herbal material.Results The HPLC fingerprint of Xuanbo Shuangsheng Granule was obtained with similarity all over 0.9.Totally 27 common peaks were confirmed,and each common peak could be found in raw herbal medicines.Based on the reference substances,5 common peaks were identified,including phellodendrine (peak 11),liquiritin (peak 22),angoroside C (peak 25),cinnamic acid (peak 26) and harpagoside (peak 27).Conclusions This method is simple,accurate,repeatable and reliable,which could be applied in the quality control of Xuanbo Shuangsheng Granule.
