Objective To study the ultrastructure of the anterior cruciate ligament.Methods Specimens were procured from seven patients with arthroscopy and observed under scanning and transmission electron microscope. Results Fibrils of normal anterior cruciate ligament arrayed in compact parallel form with waviness.Connecting fibers existed between fibrils.Diameters of fibrils were different with range of 30nm to 60nm mostly.Fibroblasts were distributed along with the fibrils.Active cells excrete filamentous collagen fibrils.Conclusion The ultrastructure of the anterior cruciate ligament was correlated with its function status.Mature fibroblasts existed in the ligament.

Objective · To evaluate the association between the abnormal maternal serum markers of alpha fetoprotein (AFP), human chorionic gonadotrophin (hCG) and unconjugated estriol (uE3) in the second trimester screening and the adverse obstetric outcomes other than trisomy 21 (T21),trisomy 18 (T18) and open neural tube defects (ONTD), and to provide local data for supporting evidence based clinical managements. Methods · A retrospective cohort study was performed in the women who received second trimester maternal serum screening in the International Peace Maternal and Child Health Hospital between 2012 and 2014, with naturally conceived singleton pregnancies. Obstetric outcomes were followed up by searching electronic medical records within the hospital. Abnormal level of marker was defined as a MOM value ≥ 99th (P99) or ≤ 1st percentile (P1) of the overall screened population. Incidence of an adverse obstetric outcome was compared between the groups with abnormal markers and the control with all markers in normal. Results · ① A total of 25616 pregnancies were included in this study, in which 4526 were identified as having various adverse obstetric outcomes. Among them 4143 pregnancies were with isolated and 383 pregnancies were with co-occurring two or more adverse outcomes. ② When compared to pregnancies with normal levels of all three serum markers, pregnancies with decreased AFP or decreased hCG did not show associations with any adverse obstetric outcomes. However, pregnancies with increased AFP, increased hCG or decreased uE3 were at increased risk for a variety of abnormal pregnancy outcome. In 18 pregnancies with an outcome of fetal chromosomal abnormalities other than T21 and T18, 9 presented with either increased AFP, increased hCG or decreased uE3, with relative risk ratios of 13.33、35.00 and 59.00, respectively. ③ The performance of those markers tended to be improved in a subset of adverse obstetric outcomes, including low birth weight

Objective To discuss the correlation between C-peptide level and autonomic neuropathy in diabetic foot in patients with type 2 diabetes mellitus (T2DM). Methods The levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h-PG) and fasting C-peptide (FC-P) were detected in 124 T2DM patients. The Neuropad was used to test functions of sudomotor nerves in foot. Patients were divided into two groups:diabetic autonomic neuropathy (DAN) group and non-autonomic neuropathy group (NDAN) according to the results of functions of sudomotor nerves in foot. Values of gender, age, body mass index (BMI), blood pressure, FBG, 2 h-PG and FC-P were compared between the two groups. The Pearson correlation analysis was carried out between the indexes mentioned above and the time for completing color change of Neuro-pad. Results There were no significant differences in gender, age, FBG and 2 h-PG between two groups (P>0.05). The FC-P level was (1.07 ± 0.75)nmol/L in DAN group, which was significantly lower than that in NDAN group (1.43 ± 1.00) nmol/L (P > 0.05). The time for completing color change of Neuropad was negatively correlated with C-peptide. Conclu-sion The autonomic nerve functions in diabetic foot is closely related with C-peptide. It is inferred that C-peptide may have protective effect on autonomic nerves in diabetic foot.

OBJECTIVE:To improve hospital's drug control level.METHODS:Quantized medicine provision management aims like stock limit,conformity rate of object-account of single category,medicine loss,mistake rate of recipe preparation,etc.were made and enforced.RESULTS:Through the above aims,medicine stock has been reduced effectively;the conformity rate of object-account has been increased;the medicine loss and incidences of mistakes in recipe preparation have been decreased.CONCLUSION:Working out feasible medicine provision management aims is an effective way to strengthen drug control.

OBJECTIVE:To carry out the ISO9001standard quality control system in the department of pharmacy.METHODS:The procedures and methods of PDCA cycle(Plan-Do-Check-Action)were applied to our department's ISO9001quality authentication standardization.RESULTS:The application of PDCA cycle-based ISO9001standards proved to be successful in the standardization of our department.CONCLUTION:The ISO9001quality authentication following the PDCA cycle is effective.

OBJECTIVE: To implement scientific drug control in inpatient dispensary by means of “Army No.1” system and to establish digitalized drug quality control system. METHODS: The “Army No.1” network system was put into wide operation in our hospital to establish interconnection among doctor workstation, nurse workstation and pharmacy workstation. Hence, the central dispensing mode was established. RESULTS: The operation of Army No.1 system not only relieved the workload of both clinic and pharmacy, increased whose working efficiency and transparency but also reduced overstock and run-off of drugs and enforced drug monitoring; meanwhile it facilitate the carrying out of pharmaceutical care and evaluation of drug utilization. CONCLUSIONS: Central dispensing mode in inpatient dispensary drug control by means of “Army No.1” system is advisable and which deserves generalization.

Objective To investigate the prevalence and significance of anti-?2-glycoprotein Ⅰ (anti-?2-GPⅠ) in patients with systemic lupus erythematosus (SLE). Methods Anti-?2-GPⅠ level was determined in 112 SLE patients, 40 patients with rheumatoid arthritis (RA), 30 patients with Sj?gren′s syndrome (SS) and 40 healthy individuals by enzyme-linked immunosorbent assay (ELISA). The laboratory and clinical features (thrombosis, fetal loss, etc) were analyzed retrospectively from the clinical database. Results Sensitivities of anti-?2-GPⅠ were 21.4%, 15.0%, 6.7% in SLE, RA and SS, respectively. The specificity of anti-?2-GPⅠ was 88.6% in SLE. Correlations between thrombosis and titers of ACL-IgG/IgM and anti-?2-GPⅠ were statistically significant. No association was found between anti-?2-GPⅠ and other clinical and laboratory features. Conclusion The results indicate that anti-?2-glycoprotein Ⅰ antibodies are common and may play a role in SLE with thrombosis. Combination of ACL and anti-?2-GPⅠ can facilitate the diagnosis of SLE with thrombosis.

OBJECTIVE:To establish quality control system by using modern scientific idea and advanced method in in?patient pharmacy.METHODS:Under the situation o f running authentication of ISO9001quality control system in our department,inpatient pharmacy should take the patients as focus to offer good and normative services to patients and clinical departments and continue to make our work better.RESULTS&CONCLUSION:Implementation of ISO9001quality control system has standardized the management of quality of inpatient pharmacy as well as increased the patients'satisfaction.And satisfactory social and economical benefits have been obtained and self-perfect and continuous improvement have been realized in the inpatient pharmacy.

OBJECTIVE:To study the control model of hospital drug stock.METHODS:We established the control model of hospital drug stock named as"ABC rule of periodical and quantitative drug management"by combining the rule of ABC classified drug management,quantitative order drug management,and periodical order drug management.RESULTS&CON?CLUSION:The drug stock was controlled reasonably by using this control model.That ensured drug neither overstocked nor run out of,the drug stock kept within the amount of sale in20days in drug storehouse,and in25days in pharmacy.

OBJECTIVE:To establishment the working model of the drug dispensing center based on Hospital Information System(HIS).METHODS:Multi-factors including the confirmation,setting and changing of the dispensing time,the retrieval of medical order,drug stock management,drug pricing,drug returning,etc.,were analyzed with digitalization.RESULTS&CONCLUSION:The working model established is convenient and practicable,and which ensures the accuracy and efficiency of drug dispensing according to medical order and drug charge collection.
