OBJECTIVETo explore the correlation between electronic bronchus mirror and Chinese medical syndrome typing of Mycoplasma pneumonia children.

METHODSTotally 198 Mycoplasma pneumonia children inpatients were assigned to three syndrome types according to Chinese medical syndrome typing and self-formulated typing standards of electronic bronchus mirror, i.e., Fei-qi accumulation of damp and heat syndrome, Fei-qi accumulation of toxicity and heat syndrome, deficient vital qi leading to lingering of pathogen syndrome. The correlation between electronic bronchus mirror and Chinese medical syndrome typing was explored.

RESULTSAs for comparison between electronic bronchus mirror and Chinese medical syndrome typing, Kappa value (K^) was 0.645 and Spearman coefficient correlation (r) was 0.653 (P < 0.01) for Fei-qi accumulation of damp and heat syndrome; K^ was 0.724 and r(s) was 0.727 (P < 0.01) for Fei-qi accumulation of toxicity and heat syndrome; K^ was 0.506 and r(s) was 0.515 (P < 0.01) for deficient vital qi leading to lingering of pathogen syndrome.

CONCLUSIONChinese medical syndrome typing of Mycoplasma pneumonia children was moderately in line with inspection typing under electronic bronchoscope with significant correlation.

Objective:To assess the periodontal diseases as a possible risk factor for preterm and low birth weight. Methods: A population-based, cross-sectional study was carried out in Hubei. The samples were chosen randomly by the rule of admittance. Socio-demographic information relating to health and maternal habits was collected through a questionnaire. The clinical parameters were debris index-simplified (DI-S), sulcus bleeding index (SBI), probing pocket depth (PD) and clinical attachment loss (CAJ). The birth time and weight were recorded. The result was analyzed with chi-square test and logistic regression analysis.Results: The incidence of preterm low birth weight was 12.3%. The gingivitis and periodontitis were diagnosed in 86.6% and 64.2% of preterm low birth weight cases. The odds ratio of having gingivitis and preterm low birth weight was 1.30(95%confidence interval: 0.53-3.22). The odds ratio of having periodontitis and preterm low birth weight was 2.69(95%confidence interval: 1.37-5.27). Conclusion: The periodontal diseases of pregnancy can be regarded as an important risk factor for preterm low birth weight.

Pioglitazone(20 mg?kg~(-1)?d~(-1)) was mixed in water fed to the diabetic treated group.After 5 wk,the left ventricle mass index(LVI),cardiomyocytes size and diameters,the content of hydroxyproline and collagen volume fraction(CVF) were measured.The left myocardium sections were made for HE,MASSON straining to observe the level of myocardial cells' hypertrophy and the accumulation of collagen individually and were examined by light microscope.Myocardial ultrastructure was studied by electronic microscope.Results Compared with untreated-DM group,the LVI,cardiomyocytes size and diameters,the content of hydroxyproline and CVF were lower in treated-DM group(P

Preeclampsia is a leading cause of maternal and infant morbidity and mortality. It is very important to explore the biomarkers for the early prediction of preeclampsia. Some peptides released from placenta, such as soluble Flt-1 and placenta growth factor (PlGF), have been revealed for definite prospects of application. Meanwhile, the recent advances in proteomics, metabolomics and microRNA shed light on searching of new biomarkers for preeclampsia prediction.

BACKGROUND:Previous research has demonstrated that preoperative hormone therapy relieved clinicaI and pathological stages of prostatic carcinoma patients,reduced positive ratio of incisaI margin:however,it did not increase disease-free surviva J rate.Worth of preoperative hormone therapy for prostatic carcinoma remains unclear.OBJECTIVE:To assess the role of preoperative hormone therapy in localised prostate cancer.METHODS:Articles were searched from PubMed,Embase.Cochrane Library(No.4,2009),Chinese biomedicaf literature database,Chinese Scientific Journals full_text database,and Chinese Journal full-text database(published before October,2009).Randomized controlled trials which were diagnosed as Iocalised prostate cancer using pathology and cytology were included The sex and nationality were not limited.and patients did not have severe heart and lung diseases Prostatic carcinoma which occurred Later or repeatedly was excluded.Otherwise.randomized controlled trails which were coincidence with the inclusion criteria were also included.Review Manager 5.0 published by Cochrane was used for stafistical analysis.Overall survival rate.disease-free survivaI rate,positive surgical margin rate,positive lymph node rate.and seminal vesicle invasion rate were evaluated.RESULTS AND CONCLUSlON:Six randomized controlled trials totaling 1 027 padicipants were included.The result of meta analysis showed that there was no significant difference in overall surviva J rate[RR=0.94,95%C,(0.86,1.02)],disease-free survival rate[RR=1.02,95%CI(0.89,1.17)],positive lymph node rate IRR=0.86,95%CI(0.47,1.57)],and seminal vesicle invasion rate[RR=1.09,95%CI(0.74,1.59)]between single prostatectomy and preoperative hormone therapy plus prostatectomy,while there was significant difference in positive surgical margin rate[RR=0.46,95%CI(0.32,0.66)]This suggested that preoperative hormonal therapy prior to prostatectomy did not improve survival rate,positive lymph nodes rate and seminaI vesicle invasion rate:however.there was a significant reduction in the positive surgicaI margin rate.

Objective To determine the median effective dose (ED50 ) of ropivacaine for spinal anesthesia when combined with sufentanil in patients undergoing caesarean section. Methods Twenty-eight ASA Ⅰ or Ⅱ parturients, aged 18-40 yr, weighing 50-110 kg, undergoing cesarean section under combined spinal-epidural anesthesia, were enrolled in this study. Combined spinal-epidural anesthesia was performed at L2,3 interspace. The mixture of ropivacaine and 5 fig sufentanil was injected into the subarachnoid space over 30 s. The initial dose of ropivacaine was 11 mg. The dose was increased/decreased by 1 mg in the next patient. The ED50 and 95% confidence interval were calculated by up-and-down method. Results The ED50 of ropivacaine was 7.780 mg (95% confidence interval 6.850-8.836 mg). Conclusion When combined with sufentanil 5 μg, the ED50 of ropivacaine for spinal anesthesia is 7.780 mg in patients undergoing caesarean section.

This study investigated the abnormal expression of ATP synthase β-subunit (ATPsyn-β) in pancreas islets of rat model of polycystic ovary syndrome (PCOS) with type 2 diabetes mellitus (T2DM),and the secretion function changes after up-regulation of ATP5b.Sixty female SD rats were divided into three groups randomly and equally.The rat model of PCOS with T2DM was established by free access to the high-carbohydrate/high-fat diet,subcutaneous injections of DHEA,and a single injection of streptozotocin.The pancreas was removed for the detection of the ATPsyn-β expression by immunohistochemical staining,Western blotting and reverse transcription-PCR (RT-PCR).The pancreas islets of the rats were cultured,isolated with collagenase Ⅴ and purified by gradient centrifugation,and the insulin secretion after treatment with different glucose concentrations was tested.Lentivirus ATP5b was successfully constructed with the vector of GV208 and transfected into the pancreas islets for the over-expression of ATPsyn-β.The insulin secretion and intracellular ATP content were determined after transfection of the PCOS-T2DM pancreas islets with Lenti-ATP5b.The results showed that the expression of ATPsyn-β protein and mRNA was significantly decreased in the pancreas of PCOS-T2DM rats.The ATP content in the pancreas islets was greatly increased and the insulin secretion was improved after the up-regulation of ATPsyn-β in the pancreas islets transfected with lenti-ATP5b.These results indicated that for PCOS,the ATPsyn-β might be one of the key factors for the attack of T2DM.

OBJECTIVE:To provide reference for medication and chemotherapy in patients with colorectal cancer. METH-ODS:Through retrospective study,case histories and doctor’s advice of the colorectal cancer patients receiving chemotherapy in our hospital during 2011-2014 were consulted to analyze the chemotherapy,medication and irrational drug use. RESULTS:A total of 593 cases of colorectal cancer patients with chemotherapy frequency of 1 940 times were collected to analyze the choice of che-motherapy regimen mainly from the following aspects:indications of chemotherapy,choice of chemotherapy regimen,chemothera-py process and chemotherapy period. There was 409 cases of irrational drug use according to the analysis of drug dosage,selection of solvents and drug concentration,the unqualified rate was 21.08% . CONCLUSIONS:The medication and chemotherapy in pa-tients with colorectal cancer in our hospital are basically rational,but there are still certain problems and shortcomings. In future clinical applications,the medication and chemotherapy need to be improved.

OBJECTIVETo evaluate the local recurrence and 5-year survival of proximal fibular osteosarcoma.

METHODSFrom October 1997 to July 2005, 12 patients with proximal fibular osteosarcoma were treated. There were 9 males and 3 females. The mean age at diagnosis was 16 (9-23) years old. Histopathological diagnosis were obtained by trut-cut biopsy, Enneking surgical stages of 12 lesions were as follows: 11 grade II B and 1 grade III. Induction chemotherapy was applied to all patients except one who left the hospital after the biopsy. Of 11 patients, 8 were performed Malawer type I resection, and 3 type II. All patients continued to get postoperative chemotherapy.

RESULTSRegular follow-up was applied. Only 1 patient was found local recurrence one year after operation and received re-resection, the others did not. Four patients died of lung metastases, including the one who did not get treated, one stage III and two II B patients. The range of follow up was 6 to 117 months. The evaluated 5 year disease-free survival of 11 patients who got treated was 72.7% by using Kaplan Meier survival analysis.

CONCLUSIONSThe local recurrence is low, and 5 year disease-free survival is acceptable, in accordance with present point that marginal resection may not impact survival for fibular osteosarcoma. No knee instability is found in this group after great care is taken for proper reconstruction of lateral collateral ligament and reinsertion of biceps femoris tendon on the lateral condyle of tibia.

【Objective】 To establish an enzyme-linked immunosorbent assay (ELISA) method for the determination of residual human coagulation factor Ⅺ in human prothrombin complex and validate the method. 【Methods】 Human factor Ⅺ was reacted with the capture antibody coated on the microtiter plate. After appropriate washing steps, biotinylated primary antibody was bound to the captured protein. Excess primary antibody was washed away and bound antibody was reacted with horseradish peroxidase conjugated streptavidin. TMB substrate was used for color development at 450 nm. The dilution reliability, accuracy, specificity, repeatability, intermediate precision, linearity, range and durability were verified. 【Results】 The verification results showed that the accuracy and specificity of this method met the experimental requirements, with an average recovery rate of 109.2% and RSD of 6.93%. The repeatability RSD was 6.78%, and the intermediate precision RSD was 6.75%, indicating good precision. The linear regression correlation coefficient of standard curve was 0.999 9, showing good accuracy and precision within the linear range. The durability was verified by the incubation time and the validity period of reagent kit opening. The results showed that the RSD of the incubation time change was 6.62%, indicating that the incubation time of this detection method was controlled between 28 to 32 minutes, and there was no significant impact on the results. The RSD of the detection results before and after the reagent kit was opened and stored under conditions for 7 days was 3.84%, indicating that the preservation of the reagent kit according to the conditions for 7 days after opening has no effect on the FⅪ detection results. Both indicated that the method had good durability. The dilution reliability results showed that there was a "hook" effect in the detection of FⅪ residue in human prothrombin complex, which could be solved by diluting 100 to 200 times. 【Conclusion】 This method can be used for the determination of FⅪ residues of human prothrombin complex in laboratory.
