OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

OBJECTIVETo analyze the relationship between the pulse pressure (PP) and atherosclerotic renal artery stenosis (ARAS) in middle-age and eldery paients with hyperensio, so as to provide the basis for the diagnosis and treatment of ARAS.

METHODSWe tetro spectively analyzed the data of 257 patients with hypertension undergoing renal arteriography at General Hospital of PLA between 2009 and 2014. Their mean age was (64.09 +/- 7.81) years. According the results of arteriography, they were divided into two groups: ARAS group (n = 145), and non-ARAS group (n = 112). Their PP and multinomial clinical indexes with ARAS were statistically analyzed.

RESULTSSingle factor correlation and Logisitic analysis showed that age, PP, serum creatinine (SCr) levels, and new onset of hypertension after 50 years of age were strongly positively related to ARAS. The age and PP and SCr was a team of continuous variable.

CONCLUSIONPP was the first new risk factor of ARAS in middile-aged and elderly patients with hypertension. It is suggested that PP may be a early predictive indicator and a new therapeutic target for ARAS.

OBJECTIVETo study the dynamic changes in the protein marker expression in the spermatogonial stem cells (SSCs) of mice at different ages by iTRAQ protein mass spectrometry and to screen new markers using the bioinformatic proteome database.

METHODSBased on the postnatal weeks, we divided 80 healthy male C57BL/6 mice into eight age groups of equal number, harvested their testicular tissues, extracted proteins following purification of the SSCs by compound enzyme digestion and magnetic-activated cell sorting. Then we analyzed and identified proteins using two-dimensional electrophoresis, protein mass spectrometry, and protein database information.

RESULTSTotally, 248,510 mass spectra were obtained from the MS experiment and 1132 proteins were identified. By the criteria of >1.2-fold for protein abundance difference and P value <0.05, we identified 298 differentially expressed proteins and 9 currently known makers of SSCs (PCNA, GFRalpha1, CDH1, Annexin A7, UCHL1, VASA, CD49f, CD29, and PLZf). Compara- tive analysis showed different expressions of the proteins in the SSCs of the mice of different ages, and the differences in the expressions of GFRalpha1, CD49f, and CD29 were consistent with the findings in other published literature. Ten proteins (P63, CD71, CD98, K19, ACE, K18, K15, K17, SH2, and SH3) were selected as SSC markers to be further studied.

CONCLUSIONThe proteins in SSCs are differentially expressed in mice of different ages. The technology of iTRAQ protein mass spectrometry can be used to analyze and compare the proteome information of mouse SSCs, obtain differentially expressed proteins in mice of different ages, and thus offers a new ap- proach to further analysis and study of the function and roles of these differential proteins.

Objective To observe the morphological and functional changes of different lung cells in hyperoxia environment.Methods Type Ⅱ alveolar epithelial cells (AECⅡ) and lung fibroblasts (LFs) of fetal rats with 18 days old were isolated and culturedin vitro, and divided into air group (placed in an atmospheric incubator, and culturing with oxygen volume fraction of 0.21) and hyperoxia group (placed in a high oxygen culture chamber, and culturing with oxygen volume fraction of 0.90). Morphological changes of two kinds of cells were observed under microscope. Cell migration was observed by scratch test. The levels of reactive oxygen species (ROS) and apoptosis in cells were detected by flow cytometry.Results After 8 hours of hyperoxia, the volume of AECⅡincreased and the cells were loosely arranged; the clearance of LFs cells was increased and arranged in disorder. Scratch test showed that, compared with air group, the immigration rate of AECⅡ was inhibited at 6 hours hyperoxia [migration rate: (38.67±1.15)％ vs. (58.67±2.31)％,P < 0.01], the immigration rate of LFs was promoted at 12 hours after hyperoxia [migration rate:(55.37±1.50)％ vs. (46.90±1.20)％,P < 0.01]. With the increase of hyperoxia time, intracellular ROS contents of two cells were gradually increased, which were significantly higher than those of the air group (fluorescence intensity:130.67±4.04 vs. 54.67±2.51, 85.00±2.00 vs. 60.33±1.52, bothP < 0.01). Both two kinds of cells showed apoptosis after exposure to high oxygen, the apoptosis rate of AECⅡ at 2 hour exposure were significantly higher than that of air group [(1.93±0.28)％ vs. (1.07±0.11)％,P < 0.05], the apoptosis rate of LFs at 6 hour exposure was significantly higher than that of air group [(1.66±0.09)％ vs. (1.46±0.09)％,P < 0.05].Conclusion High concentration of oxygen can cause poor growth of lung cells, reduce AEC Ⅱ migration level and increase LFs migration, and the production of intracellular ROS eventually leads to apoptosis of lung cells.

Abstract: Objective　To find out the existing problems and provide reference for further improving the quality of report information by analyzing the report cards of COVID-19 and the positive report cards of primary screening reported in Ningxia. Methods　All COVID-19 case cards from 2020 to 2021 and initial screening positive cards were derived from the Chinese Information System for Disease Control and Prevention according to final review date. The timeliness of case reporting, timeliness of case review, completeness and accuracy of the case cards were analyzed. Results　In Ningxia, the first case of COVID-19 was reported on January 20, 2020, and as of December 31, 2021, 122 confirmed cases and 4 symptomatic infected cases were reported. In 2021, the timely reporting rate of COVID-19 was 98.00%, which increased by 8.24% compared with 2020 (90.54%). Compared with 2020, the average time limit for diagnosis to reporting of COVID-19 in 2021 was shortened by 83.12%; in 2021, the timely review rate of COVID-19 was 100.00%, which increased by 13.84% compared with 2020 (87.84%). Compared with 2020, the time from reporting to final review was shortened by 98.91%. In 2021, the timely rate of positive reports in COVID-19 in Ningxia was 90.00%, among which the timely rate of reports by county (district) nucleic acid detection institutions was the highest (92.31%), followed by municipal (91.67%) and autonomous region (81.82%). Conclusions　At the beginning of the epidemic in 2020, the timeliness of COVID-19 in Ningxia was poor, and through the implementation of measures such as technical training, supervision and inspection to continuously optimize the staffing of medical institutions and disease control institutions, the timeliness of reporting COVID-19 in Ningxia in 2021 was substantially improved, but there were still some weak links. In the future work, technical guidance and training should be carried out for weak links, and efforts should be made to improve the quality of reports.

OBJECTIVETo investigate the effects of single heat stress treatment on spermatogenic cells in mice.

METHODSWe randomly divided 36 C57 male mice into a control and a heat stress treatment group and submerged the lower part of the torso in water at 25 °C and 43 °C, respectively, both for 15 minutes. At 1, 7, and 14 days after treatment, we obtained the testicular organ indexes, observed the changes in testicular morphology by HE staining, and determined the location and expression levels of the promyelocytic leukemia zinc finger (PLZF) and synaptonemal comlex protein-3 (SCP-3) in the testis tissue by immunohistochemistry and Western blot.

RESULTSThe testicular organ index was significantly lower in the heat stress treatment than in the control group (P < 0.05). Compared with the controls, the heat shock-treated mice showed loosely arranged spermatogenic cells scattered in the seminiferous tubules at 1 day after heat stress treatment, atrophied, loosely arranged and obviously reduced number of spermatogenic cells at 7 days, and relatively closely arranged seminiferous tubules and increased number and layers of spermatogenic cells at 14 days. The number of SCP-3 labelled spermatocytes obviously decreased in the heat stress-treated animals at 1 and 7 days and began to increase at 14 days. The PLZF protein expression was significantly reduced in the heat stress treatment group at 1 day as compared with that in the control (0.19 ± 0.12 vs 0.64 ± 0.03, P < 0.01), but elevated to 0.77 ± 0.02 at 7 and 14 days, even remarkably higher than in the control animals (P < 0.01).

CONCLUSIONHeat stress treatment can induce short-term dyszoospermia in mice, which can be recovered with the prolonged time after treatment.

Objective To judge method performance of routine biochemistry parameters on Roche Modular PPI testing system by using westgard's method evaluation decision chart.Methods We assessed imprecision(CV)from internal quality control and inaccuracy(bias)from external quality control evaluation.Combined estimates of imprecision and inaccuracy by plotting imprecision as the x-coordinate and inaccuracy as the y-coordinate to locate an expected operating point of every item on the chart.By comparing this operating point with allowable total errors(TEa),we can decide whether the performance is acceptable or not.Results In the 27 different parameters tested,imprecision and bias of calcium were 0.08 mmol/L and 0.06 mmol/L respectively,its performance was marginal.The imprecision of creatinine,urea,glucose, sodium,chloride and phosphorus were 3.20%,2.13%,1.52%,0.89 mmol/L,1.10% and 1.55%,the bias were 4.79%,0.96%,4.63%,0.80 mmol/L,1.74% and 4.13% respectively,their performance was good.M1 other 20 items were of excellence performance.Conclusions Routine biochemistry parameters on Roche Modular PPI testing system possessed good precision and accuracy,and their performance were acceptable.To judge method performance of biochemistry testing system by using westgard' s method evaluation decision chart was easy to do and suited for clinical laboratory.

OBJECTIVETo investigate the distribution of metastatic pelvic lymph nodes in the women with early stage cervical carcinoma, and the feasibility of dividing these nodes into three stations in those patients.

METHODS(99m)Tc-DX of 2 ml was injected into the cervix to a depth of 5 to 10 mm at 3, 6, 9, 12 o'clock positions preoperatively in 196 patients with early stage cervical cancer. Pelvic lymphadenectomy and radical hysterectomy were performed in all patients. Pelvic lymph nodes were detected by gamma-probe. The sentinel lymph nodes (SLN) were determined if the radioactivity reached 5 times higher than that in the ipsilateral nodes. All resected pelvic lymph nodes were examined by histopathology with HE stained serial sections.

RESULTSOf the 196 patients, 41 were found to have metastasis in 83 lymph nodes. The metastatic rate was 78.3% (65/83) in the parametrial and obturator lymph nodes, 20.5% (17/83)in the internal and external iliac lymph nodes, 1.2% (1/83) in the commmon iliac lymph nodes. Of the 22 patients with metastatic parametrial lymph nodes, metastatic external iliac lymph nodes were detected in 5 patients, and metastatic internal iliac lymph nodes in 3 patients. Among the 19 patients with metastatic obturator lymph nodes, metastatic external iliac lymph nodes were found in 4 patients, and metastatic internal iliac lymph nodes in 3 cases. It was shown by Chi-sqare test that the metastases in parametrial and/or obturator lymph nodes were positively correlated with lymph node metastases in other pelvic sites. Eighty-one SLN were found to have metastasis. The metastatic rate of parametrial and obturator SLN was 79.0% (64/81) versus 21.0% (17/81) of internal and external iliac SLN. No statistically significant difference in 1- and 3-yr survival was observed between the groups with and without metastasis in parametrial and obturator lymph nodes, while the 5-yr survival rate in the patients without metastatic lymph node was 93.2%, significantly higher than that of patients with lymphatic metastasis (65.1%).

CONCLUSIONIt is feasible for cervical cancer to divide the pelvic lymph nodes into three levels. The level I lymph nodes consist of parametrial and obturator lymph nodes. Internal and external iliac lymph nodes can be considered as level II lymph nodes, and the common iliac and inguinal lymph nodes as level III nodes. A rational treatment plan can be made according to the distribution of metastatic pelvic lymph nodes.

OBJECTIVETo explore seroepidemiological status and vaccine coverage of hepatitis B in children aging under 15 years old in Chaoyang district of Beijing.

METHODSA total of 1602 children aging under 15 years old, residents or floating population who had lived here more than six months, were randomly selected by multistage cluster sampling, from Chaoyang district of Beijing in year 2010. The demographic information and vaccine coverage of hepatitis B vaccine (HepB) were collected by self-designed questionnaire.5 ml blood was collected from each subject and the serum HBsAg, anti-HBs and anti-HBc were detected by Abbott microparticle enzyme-linked immunoassay. Those whose HBsAg was positive were then tested HBeAg and anti-HBe. The positive rate of hepatitis B indicators and coverage rate of HepB in different population were compared.

RESULTSThe positive rate of HBsAg, anti-HBs and anti-HBc were 0.56% (9/1602), 64.17% (1028/1602) and 2.12% (34/1602), respectively; while the age standardized rates were separately 0.57%, 66.36% and 1.98%; and the gender-adjusted rates were 0.56%, 64.23% and 2.12% respectively. The positive rate of anti-HBs was statistically significant (χ(2) = 165.445, P = 0.000). The positive rate of anti-HBs was up to 90.73% (235/259) among 1-2 years old children, followed by 76.22% (141/185) among 13 - 15 years old children, 67.21% (166/247) among 3 - 4 years old children, 61.22% (150/245) among 9 - 10 years old children, 60.68% (142/234) among 11 - 12 years old children, 49.05% (103/210) among 5 - 6 years old children and 40.99% (91/222) among 7 - 8 years old children. The average coverage rate of HepB was 90.44% (1371/1516), separately 93.76% (661/705) in residents and 87.55% (719/811) in floating population. The difference was statistically significant (χ(2) = 16.829, P = 0.000).

CONCLUSIONHBsAg positive rate in children under 15 years old in Chaoyang district of Beijing dropped to less than 1% and the coverage rate of HepB had reached over 90%. It is suggested that we should pay more attention to increase the coverage rate of HepB among floating children under 15 years old.
