OBJECTIVE:To determine the contents of hydrochloric stachydrine in the shenning granule by TLC-scanning Method.METHODS:The acetone-dehydrated alcohol-HCl(10∶6∶1)were used as developing agents,the potassium hep-taiodobismuthate test solution-1%trichloride ferric dehydrated alchhol solution(2∶1)were used as the color-developing a-gents,the detection wavelength was530nm,the reference wavelength was670nm,the slit size was0.4mm?0.4mm,the lin-earization parameter Sx=3.RESULTS:The spot peak area score assumed a satisfactory linear relationship when the electric sample size for the hydrochloric stachydrine at a range of2.412?g～6.432?g(r=0.9972),the recovery was98.93%(RSD=1.15%).CONCLUSION:This method is simple,accurate,and this determination method has a good reproducibility,which can be used for the quality control of the shenning granule.

Objective To investigate the effect of labor induction of full-term pregnancy use of oxytocin,and the incidence of adverse reactions of mode of delivery of cervical dilatation balloon with pubeisheng.Methods The clinical data of full-term pregnant women who were delivered in our hospital from October 2014 to November 2015 were retrospectively analyzed,According to the induction of labor is divided into the way of pubeisheng group and cervical dilation balloon group.The differences of delivery mode,oxytocin utilization,maternal and neonatal outcomes and adverse reactions were observed between the two groups.Results Cervical dilatation balloon group vaginal delivery rate was 90.38％,higher than that of pubeisheng group(P<0.05); oxytocin use rate of 11.54％,lower than that of pubeisheng group(P<0.05); Cervical dilatation balloon group first,second and third labor time is shorter pubeisheng group(P<0.001); The cervical dilation balloon group bleeding more than pubeisheng group(P<0.001),two groups of infection,urinary retention complication rate had no significant difference.Two groups of neonatal aspiration pneumonia incidence rate had no significant difference after the birth of 1min Apgar score difference,and cervical dilatation balloon group after the birth of 5min Apgar was higher than that of pubeisheng group(P<0.05).Conclusion The application of cervical dilation balloon in the induction of labor in term pregnancy is better,which can significantly improve the rate of vaginal delivery,reduce the use rate of oxytocin and shorten the labor process,and has the value of clinical application.

Objective To study the long term effect and practical value of unilateral cleft lip repair with extended Mohler surgery based on over 10 years experiences.Methods A lot of 320 cases with unilateral cleft lip were repaired with extended Mohler surgery at average age of 5 months and 20 days.65 repaired cases were followed up and long term treatment result was evaluated.26 cases were evaluated in 10.5 to 15 years after surgery.39 cases were evaluated in 6 to 24 months after surgery.And the details of surgery were described.Results Excellent results for most of cleft patients (63 cases, 97%) were achieved, which included unobvious vertical scar symmetric to unaffected philtrum column, symmetric cupid's bow, nostrils and intermedial nasal columellae.Conclusions Extended Mohler surgery is great valuable for unilateral cleft lip repair.Appropriate indications should be stressed.

ObjectiveToinvestigatetheeffectsofcaveolin1(Cav1)onexpressionsofproinflammatory cytokine interleukin (IL)-1βand IL-6 in the ischemic cortex after permanent middle cerebral artery occlusion in mice. Methods The Cav-1 knockout mice (n=40) and wild-type mice (n=40) were randomly divided into ischemia groups and sham operation groups (n=20 in each group). They w ere also redivided into ischemia or sham operation at 3, 7, 10 and 14 d time points ( n=5 in each time point). A permanent middle cerebral artery occlusion model w as induced by the suture method. Immunohistochemical method w as used to detect the expressions of IL-1βand IL-6 in the ischemic cortex. Results The expression levels of IL-1βand IL-6 in the ischemic cortex at each time point in the ischemia group in Cav1 knockout mice w ere significantly higher than those in the ischemia group in the w ild-type mice ( al P< 0.05 ). Conclusions The upregulations of proinflammatory cytokines IL-1βand IL-6 in the ischemic cortex in Cav1 knockout mice suggests that Cav1 plays an important role in aleviating inflammation after cerebral ischemia.

Objective To explore the expression of costimulatory molecules of CD28 and CD152 for patients with chronic hepatitis B(CHB).Methods Flow cytometric analysis was applied to detect the expression level of CD28/CD152 on CD4+ or CD8+ T lymphocyte subpopulations.Results Compared with control group,the percentage of CD4+CD28+ and CD8+CD28+ increased significantly(P

Regulation of gene expression is one of the most importa nt responses of cells to DNA damage induced by radiation. A novel expressed seq u ence tag (EST) fragment had been cloned from human embryo lung cells induced by 50cGy radiation and named RIG1. To clone the full-length cDNA of RIG1, a non-c loned cDNA library of human embryo lung cells induced by low dose irradiation ha d been established. This library was used as template in enchanced nest RACE PCR and biotin-labeled probe was used for further purification. The 3′ flanking s equence of this EST was cloned and sequenced with this set of technology. It was illuminated by homology analysis that this 3′ flanking sequence and the origin al EST are well aligned with a BAC clone of 20th chromosome and the predic ted exons sequence of this chromosome is well consisten ce with the real EST. Thus the RIG1 can be roughly located in 20th chromos ome. By use of the exons sequence predicted from chromosome sequence by GENSCA N, full-length of RIG1 gene has been cloned. Chromosome location of RIG1 gene i s further determined by this successful verification of Bioinformatics predictio n by experiment. By the same step, genome sequence of RIG1 has been determined. Therefore,by the combined use of Bioinformatics analysis，the full-length cDNA sequence and genome sequence of RIG1 gene are obtained and the predicted protei n sequence is determined.

OBJECTIVE To summarize the clinical experience of endoscopic thyroidectomy via suprasternal approach. METHODS Endoscopic thyroidectomy via suprasternal approach was performed in 35 patients with ultrasonic scalpel. RESULTS Operations were successfully performed in 35 patients. The mean operation times were 130 (105～190) minutes in 24 cases with subtotal lobectomy and 4 case with total lobectomy, 60 (50～70) minutes in 2 cases with isthmectomy, 228 (185～270) minutes in 2 case with bilateral subtotal lobectomy, 163 (140～215) minutes in 3 case with subtotal lobectomy and the contralateral ademona resection .The bleeding during operation was 5 to 40ml and the average hospital stay time was 4 (3～5) days. CONCLUSION Endoscopic thyroidectomy via suprasternal approach is a safe way with good cosmetic value.

Objective To explore the relationship between bronchoalveolar lavage fluid (BALF) Mycoplasma load and clinical characteristics in children with Mycoplasma pneumoniae (MP) pneumonia.Methods MP DNA was quantitatively detected by fluorescent real-time PCR in BALF from 67 children with MP pneumonia.They were classified into three groups:low MP load group (＜ 103/ml,21 cases),moderate MP load group (103-106/ml,22 cases) and high MP load group (＞ 106/ml,24 cases).Clinical symptom,main laboratory and imaging results of children among three groups were compared.Results When compared with low MP load group and moderate MP load group,high MP load group had longer fever duration [(7.4 ± 2.6),(10.0 ± 2.4) d vs.(12.4 ± 2.7) d],longer time to normalization of temperature with macrolide administration [(4.2 ± 1.0),(8.5 ± 2.4) d vs.(10.8 ± 4.4) d],more patients with high fever,there was significant difference (P ＜ 0.05).Statistically significant difference existed in C-reactive protein among three groups [(3.0 ± 1.4),(11.5 ±7.6),(34.0 ± 10.1) mg/L] (P =0.004).Large field of consolidation or atelectasis were found in 58.3％ (14/24) of high MP load group,much higher than 22.7％ (5/22) in moderate MP load group and 14.3％ (3/21) in low MP load group.Bilateral or massive pleural effusion was not found in low MP load group,while in moderate MP load and high MP load group,they were 13.6 ％ (3/22) and 25.0％ (6/24)(P =0.033).Conclusions There is a close relationship between MP load in BALF and clinical characteristics in children with MP pneumonia.Those with high MP load have a more severe process.
