Total glucosides of paeony root ( TGPs ) ( 5 ~40mg/kg, ip ) had a dose-related hypothermal effect in mice and rats, which was related to the environment temperature. But TGPs ( 40mg/kg, ip or iv ) showed no significant hypothermal effect in guinea-pigs or rabbits. TGPs ( 2, 4 mg/kg, icv ) had a potential hypothermal effect in rats. Chlopheniramine had antagonist effect on hypothermal effect of TGPs in mice and rats.

Case-based learning model was applied in teaching the course of Clinical Biochem-istry and Diagnosis for postgraduates with professional degree. Dyslipidaemia was chose as teaching content and one distinctly characterized case along with four typical cases were selected. Information of cases and core problems were submitted to students to prepare before the class. In the class, stu-dents were grouped and discussed independently. Students put forward the pathogenesis of the disease and the clinical laboratory test items for diagnosis and differential diagnosis. Teachers should adhere to the following principles: making the class student-centered and highlighting consciousness of stu-dents; creating clinical environment to stimulate enthusiasm for learning; problem-oriented and taking capacity building as the priority. After the class, teaching evaluation was designed to promote the con-tinuous improvement of teaching cases.

Background and purpose: The protein tyrosine kinase-7 (PTK7) gene may be related to the occurrence and progression of many tumors. This study was aimed to explore the expression of PTK7 in ovarian serous tumors and its relationship with clinical stage, histological grade, metastasis and prognosis indicators linkages, and analyze the diagnostic and prognostic value of PTK7 in ovarian serous tumors. Methods:Expressions of PTK7 in 3 ovarian cell lines (HO8910, SKOV3, A2780), 14 cases of normal fallopian tube epithelium, 6 cases of benign serous ovarian tumors, 51 cases of borderline serous ovarian tumors and in 97 cases of ovarian serous carcinoma were detected by immunohistochemical EliVision two-step method. Statistical analysis of the relationship between the expression of PTK7 and the pathological indicators was performed byχ2 test, Fisher exact test and Kaplan-Meier method. Results:PTK7 was negatively expressed in HO8910 and A2780, but weakly positively expressed in SKOV3. The positive rates of PTK7 in normal fallopian tube epithelium, benign serous ovarian tumors, borderline serous ovarian tumors and serous ovarian cancer were 92.86%(13/14), 83.33%(5/6), 45.10%(23/51), and 28.87%(28/97), respectively. The expression of PTK7 had no difference between normal fallopian tube epithelium and benign serous tumors, benign serous tumors and serous borderline tumors (P=0.521, P=0.102). The PTK7 expression showed signiifcant differences in serous ovarian carcinoma compared with those in normal epithelium, benign serous tumors and borderline serous tumors (P=0.000, P=0.012, P=0.048). Expression of PTK7 in borderline serous ovarian tumors was signiifcantly with clinical stage, metastasis (lymph node and/or peritoneum metastasis) (P=0.038, P=0.038), rather than its location, age (P=0.088, P=0.896). Expression of PTK7 in ovarian serous carcinoma had a signiifcant relation with its clinical stage, WHO grade, MDACC grade (P=0.011, P=0.004, P=0.000), rather than its location, metastasis, tumor diameter and age (P=0.326, P=0.524, P=0.588, P=0.584). The survival rate of PTK7 positive group in ovarian serous carcinoma was signiifcantly higher than that in the negative control group (P=0.017). Conclusion:The expressions of PTK7 in normal ovarian epithelium, benign serous ovarian tumors, borderline serous ovarian tumors and epithelial serous carcinoma show a gradual downward trend. The expression of PTK7 in ovarian serous tumors has a positive correlation with late clinical stage, high histological grade and poor prognosis. PTK7 can be a new indicator of clinical diagnosis and prognosis in ovarian serous tumors.

Objective:To explore the clinical effect of traditional Chinese medicine(TCM) fumigation-washing therapy combined with etofenamate cream wiping in the treatment of knee osteoarthritis.Methods:From September 2018 to April 2019, 176 cases of knee osteoarthritis were divided into two groups according to random number table method.The observation group (91 cases) was treated by etofenamate cream based on fumigation-washing therapy with TCM, while the control group (85 cases) was treated by etofenamate cream wiping only.Both two groups continued treatment for 2 weeks.The Lequesne score and effective rate of the two groups were achieved and analyzed.Results:At 1 d and 2 weeks after treatment, there were no statistically significant differences in the Lequesne score between the two groups(all P>0.05). After treatment for 1 month and 3 months, Lequesne scores of the observation group[(4.1±1.1)points, (4.6±1.0)points] were lower than those of the control group [(6.2±1.2)points, (7.5±1.4)points]( t=12.155, 15.598, all P<0.05). At 1 d and 2 weeks after treatment, there were no statistically significant difference in the effective rate between the two groups(all P>0.05). After treatment for 1 month and 3 months, the effective rates of the observation group were 63.7%(58/91) and 61.5%(56/91), respectively, which were higher than those of the control group [41.2%(35/85) and 18.8%(16/85)] (χ 2=8.98, 33.17, all P<0.05). Conclusion:Fumigation-washing therapy with TCM combined with etofenamate cream wiping has quick, lasting and safe effect in the treatment of knee osteoarthritis.

Objective: The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome). Methods: Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4⁺T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on. Results: Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ²=138.35, P<0.001). The proportion of Han HIV/AIDS with non-commercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ²=6.32, P=0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non-marital sexual partners (11.1%(8)) (χ²=61.10, P<0.001). The proportion of HIV/AIDS with non-commercial transmission who lived mobile was 72.9% (94), which was higher than who lived fixedly (52.2%(412)) (χ²=19.34, P<0.001). Qualitative interviews results revealed that the age of the respondents were 22-69. Respondents whose ages are in 22-34 were more likely to use mobile phone (4/10) and respondents whose ages are in 35-69 were less likely to look partners through party and the context of working. Conclusion The proportion of cases being infected by non-marital and non-commercial heterosexual transmission in Qian dongnan was higher than general national levels. The characteristics of sex, marriage status, migration, vocation, the members of non-marital sex partners were significant differed between commercial heterosexual transmission and non-marital and non-commercial heterosexual transmission.

Objective:To explore the correlation of serum albumin level at admission with clinical prognoses in patients with acute traumatic brain injury (TBI).Methods:One hundred and fifty-four patients with acute moderate-extreme severe TBI (Glasgow Coma Scale [GCS] scores of 3-12 at admission) in Department of Neurosurgery, General Hospital of Western Theater Command from January 1, 2019 to December 31, 2020 were chosen. The comprehensive clinical data of these patients were collected, including age, gender, GCS scores, serum albumin level (hypoalbuminemia defined as<35 g/L), hemoglobin level, comorbidities, treatment measures, and prognoses 6 months after discharge (poor prognosis defined as Glasgow outcome Scale [GOS] scores of 1-2, and good prognosis defined as GOS scores of 3-5). Univariate and multivariate Logistic regressions were used to identify the independent factors for clinical prognoses of these patients, and differences in poor prognosis rate, length of ICU stay, and total hospital cost were compared between different groups.Results:Among the 154 patients, 43 had poor prognosis and 111 had good prognosis. Serum albumin level at admission ( OR=0.916, 95% CI: 0.843-0.996, P=0.001) and GCS scores at admission ( OR=0.701, 95% CI: 0.594-0.828, P<0.001) were independent factors for prognosis. Patients with hypoalbuminemia ( n=70) displayed significantly higher poor prognosis rate, longer ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=84, P<0.05); specifically, in patients with GCS scores of 9-12 at admission ( n=58), those with hypoalbuminemia ( n=27) exhibited significantly higher poor prognosis rate, longer ICU stays, and higher total hospitalization cost than their non-hypoalbuminemia counterparts ( n=31, P<0.05); similarly, in patients with GCS scores of 3-8 at admission ( n=96), those with hypoalbuminemia ( n=74) had significantly higher poor prognosis rate than their non-hypoalbuminemia counterparts ( n=22, P<0.05). In patients with good prognosis, those with hypoalbuminemia ( n=56) showed significantly longer total hospital stays, prolonged ICU stays, and increased total hospitalization cost compared with those without hypoalbuminemia ( n=55, P<0.05). Conclusion:Low serum albumin level at admission is likely to lead to poor prognosis, prolonged ICU stays and increased total hospitalization cost in patients with acute TBI.

Diamond-like carbon (DLC) films were deposited by acetylene plasma immersion ion implantation-deposition (PIII-D) on biomedical polyethylene terephthalate (PET). The capacities of Staphylococcus aureus (SA), Staphylococcus epidermidis (SE), Escherichia coli (EC), Pseudomonas aeruginosa (PA) and Candida albicans (CA) for adhesion to PETs are quantitatively determined by the plate counting and Gamma-ray counting of 125I radio labeled bacteria in vitro. The results indicate that the capacities of five types of bacteria for adhesion to PETs are all suppressed by C2H2 PIII-D (P<0.05). The surface energy components of the various substrates and bacteria are calculated based on measurements in water, formamide and diiodomethane and Lifshitz-van del Waals/acid-base approach (LW-AB). The surface free energies obtained are used to calculate the interfacial free energies of adhesion (deltaF(adh)) of five kinds of bacteria on various substrates, and the results show that it is energetically unfavorable for bacterial adhesion to the DLC films already deposited on PET by C2H2 PIII-D.
