Current reform of higher medical education focuses on curriculum integration and corresponding reconstruction of teaching system. Chongqing Medical University has carried out the reform of medical personnel training mode from basic to clinical, which has achieved certain results. Three aspects including teaching content, teaching methods and appraisal system of the urogenital system curriculum integration are introduced in the paper. In the teaching content, the parts related to urogenital system in basic subjects and clinical subjects are extracted and integrated. In the process of teaching implementation, a teaching team is set up across departments and multidisciplinary joint teaching is carried out. In order to arouse the enthusiasm of students, inspire and cultivate students' scientific research thinking by improving teaching methods, several teaching methods such as case introduction teaching method, question discussion and debate meeting are used. Scientific evaluation system is used to observe and record the whole process of students' learning. Meanwhile, some existing problems and solutions of curriculum integration are discussed in the paper to provide references for peers in relevant colleges and universities.

To investigate the effect of atorvastatin on lipid metabolism in type 2 elder diabetes patients with hyperlipidemia, 26 patients with type 2 elder diabetes complicated with hyperlipidemia were treated with atorvastatin (10 mg/d) for 8 weeks. The serum triglyceride (TG), high density protein cholesterol (HDL-C) and low density protein cholesterol (LDL-C) were measured before and after the treatment. Meanwhile, the non-denaturing polyacrylamide gradient gel electrophoresis was used for detection of small-sized LDL(SLDL). Our results showed that TG dropped from 4.88 +/- 0.72 mmol/L to 2.65 +/- 0.32 mmol/L; HDL-C was increased from 0.85 +/- 0.31 mmol/L to 1.28 +/- 0.29 mmol/L; LDL-C was declined from 3.71 +/- 2.98 mmol/L to 2.10 +/- 1.22 mmol/L, sLDL-A was increased from (42.49 +/- 8.1)% to (53.27 +/- 7.5)%; LDL-B was decreased from (57.91 +/- 8.1)% to (46.73 +/- 7.5% ) (P<0.05). The level of blood glucose was not changed at the end of 8th week. It is concluded that atorvastatin has satisfactory lipid-regulating effects on type 2 elder diabetes patients with hyperlipidemia.

OBJECTIVETo study the clinical characteristics of human bocavirus (HBoV) among children and to understand the association of HBoV with human diseases.

METHODTotally 148 nasopharyngeal aspirate (NPA) samples were collect from hospitalized children with acute respiratory infection during Oct. 2005 to Feb. 2006. Two serum samples were obtained from HBoV positive patients. PCR was used to assay all these samples and PCR products were sequenced.

RESULTHBoV was positive in 11 of 148 NPA samples. The positive rate was 7.4 percent. The serum samples of HBoV infected patients showed that serum contained HBoV by PCR assay. All these HBoV positive patients had the clinical symptoms of bronchitis, bronchopneumonia and pneumonia. Some patients had diarrhea.

CONCLUSIONAll patients infected with HBoV had upper and lower respiratory tract infections. HBoV is a probable important pathogen of upper and lower respiratory tract infection. The HBoV could cause viremia. In addition, some HBoV patients had diarrhea. HBoV infection probably could also result in intestinal disease and other related symptoms.

OBJECTIVETo observe the correlation between human papillomavirus (HPV) infection and cervical lesion among women living in community of Beijing.

METHODSA total of 795 women at age 20-54, living in Zhanlanlu District of Beijing were screened for cervical lesion. Samples of cervical cytology (LCT) and HPV test (hc2) were collected. Colposcopy and biopsy were conducted in women with positive LCT.

RESULTSIn those 795 women, the infection rate of HPV was 14.1% (112/795). In 40 women who were LCT positive 1 early invasive cervical cancer, 4 cervical intra-epithelial neoplasia (CIN3), 3 CIN2 and 7 CIN1 were noticed. In 750 women with negative LCT, 5 CIN1 and 1 low-grade CGIN were diagnosed. In those women who were Cyto(+) and HPV(+), 15 cases (55.6%, 15/27) were diagnosed with > or = CIN1 (including 7 CIN1, 3 CIN2, 4 CIN3 and 1 early invasive cancer).

CONCLUSIONThe risk of cervical lesion significantly increased in women showing positive in cytology and HPV test.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.

Lipooligosacharide (LOS) of Neisseria gonorrhoeae (gonococci, GC) is involved in the interaction of GC with host cells. Deletion of the alpha-oligosaccharide (alpha-OS) moiety of LOS (lgtF mutant) significantly impairs invasion of GC into epithelial cell lines. GC opacity (Opa) proteins, such as OpaI, mediate phagocytosis and stimulate chemiluminescence responses in neutrophils in part through interaction with members of the carcinoembryonic antigen (CEA) family, which includes CEACAM3 (CD66d), a human neutrophil specific receptor for phagocytosis of bacteria. In the present work, we examined the effects of OpaI-expressing lgtF mutant on phagocytosis by HeLa-CEACAM3 cells and chemiluminescence responses in neutrophils. The results showed that lgtF mutant even expressing OpaI completely lost the ability to promote either phagocytosis mediated by CEACAM3 interaction in HeLa cells or chemiluminescence responses in neutrophils. These data indicated that Opa proteins in the lgtF mutant, which might result from the conformational change, cannot be functional.

Chloroquine (CQ) phosphate has been suggested to be clinically effective in the treatment of coronavirus disease 2019 (COVID-19). To develop a physiologically-based pharmacokinetic (PBPK) model for predicting tissue distribution of CQ and apply it to optimize dosage regimens, a PBPK model, with parameterization of drug distribution extrapolated from animal data, was developed to predict human tissue distribution of CQ. The physiological characteristics of time-dependent accumulation was mimicked through an active transport mechanism. Several dosing regimens were proposed based on PBPK simulation combined with known clinical exposure-response relationships. The model was also validated by clinical data from Chinese patients with COVID-19. The novel PBPK model allows in-depth description of the pharmacokinetics of CQ in several key organs (lung, heart, liver, and kidney), and was applied to design dosing strategies in patients with acute COVID-19 (Day 1: 750 mg BID, Days 2-5: 500 mg BID, CQ phosphate), patients with moderate COVID-19 (Day 1: 750 mg and 500 mg, Days 2-3: 500 mg BID, Days 4-5: 250 mg BID, CQ phosphate), and other vulnerable populations (.., renal and hepatic impairment and elderly patients, Days 1-5: 250 mg BID, CQ phosphate). A PBPK model of CQ was successfully developed to optimize dosage regimens for patients with COVID-19.

OBJECTIVETo assess the effect and safety of Jinhua Qinggan Granule (JHG) in treating influenza patients of wind-heat affecting Fei syndrome (WHAFS).

METHODSTotally 136 influenza patients of WHAFS were randomized by stratification into 3 groups, the high dose JHG group (44 cases, 10 g each time), the low dose JHG group (45 cases, 5 g JHG + 5 g placebo each time), and the placebo control group (47 cases, 10 g placebo each time). All medication was administered three times daily for 5 days. The fever disappearance time, the fever disappearance rate, efficacy of TCM syndrome, the disappearance rate of main symptoms and physical signs of flu, the negative rate of virus nucleic acid in the pharyngeal secretion, and safety indicators were assessed.

RESULTSThe median fever disappearance time was 32.8 h (95% CI: 22.5-41.0 h) in the high dose JHG group, 26.0 h (95% CI: 14.5-36.5 h) in the low dose JHG group, 39.5 h (95% CI: 29.0-46.0 h) in the placebo control group. There was statistical difference in the median fever disappearance time between the low dose JHG group and the placebo control group (P = 0.011). Three days after treatment, the markedly effective rate of TCM symptoms in the low dose JHG group was 66.7%, higher than that of the placebo control group (38.3%), and its effective rate was superior to that of the high dose JHG group (P = 0.043). Five days after treatment, the recovery rate of the low dose JHG group (42.2%) was higher than that of the high dose JHG group (25.0%, P = 0.026) and that of the placebo control group (14.9%, P = 0.002). The markedly effective rate of the low dose JHG group (86.7%) was higher than that of the placebo control group (55.3%, P = 0.001). Similar effects were obtained in the low dose JHG group and the high dose JHG group, but slightly poor in partial indicators of the high dose JHG group. There was no statistical difference in adverse reaction among these three groups (P > 0.05).

CONCLUSIONSJHG was effective and safe in treating influenza patients of WHAFS. Routinely low dose was the optimal dosage of JHG.
