Objective To investigate the efficacy of metholrexate combined with rmifepristone and laparoscopic surgery for treating ectopic pregnancy.Methods 85 patient with ectopic pregnancy were selected.41 cases treated with methotrexate and mifeprisione were considered as the control group,while 44 cases with laparoscopic surgery were considered as the observalion group on the voluntary basis.The clinical efficacy,serum β-HCG value and recovery time after 7d were compared between the two groups.Results After the treatment,the cure rate in the observation group was 100％ which was significantly higher than 90％ of the control group ( P ＜ 0.05 ),the serum β-HCG value of the observation group was lower and the restoration normal time was shorter than the control group ( P ＜0.05).Conclusions Laparoscopic surgery and conservative treatment of methotrexate combined with mifepristone are effective in the treatment of ectopic pregnancy.However,the clinical efficacy of the laparoscopic surgery is better and it has rapid recovery time,and it can completely cure the patients.

Objective To assess the curative effect and safety of endoscopic therapy at duodenum elevated lesions. Methods We retrospectively studied the clinical data including general data, the procedure of performance, the lesions pathological characters, complications and recurrence after the treatment of patients who underwent endoscopic treatment. Results 111 patients of 112 patients were treated by endoscopic treatment successfully, 1 case was treated by surgery. 49 lesions were treated by electrocoagulation, 36 lesions were treated by polypectomy or endoscopic mucosal resection (EMR), 27 by endoscopic submucosal dissection (ESD). Complication rate was 16.96%(19/112), 1 case of active bleeding was treated by surgery in hemostasis difficulty. 6 cases of perforation, 2 cases of delayed bleeding, 2 cases of transient increase in amylase level and 1 case of delayed perforation. All the patients were successfully performed. Post-operation follow-up period was 1~12 months. Conclusion Endoscopic treatment holds advantages of minimally invasive, quick recovery, low cost, and less risk which may be play an important role in duodenal elevated lesions.

OBJECTIVE:To investigate the effect of different processing methods on 4 kinds of flavonoids contents in salt-pro-cessed Cuscuta chinensis. METHODS:Salt-processed C. chinensis piece was processed with different baking temperature (70 ℃, 100℃,130℃,160℃,190℃and 210℃),baking time(10 min,15 min,30 min,45 min,60 min and 75 min)and moisten-ing time(0.5 h,1 h,2 h,4 h and 6 h). HPLC was adopted for contents determination of hyperoside,rutin,quercetin and kaemp-ferol:the column was Synergi 4u Hydro-Rp 80A with mobile phase of methanol- 0.1% phosphoric acid (gradient elution) at a flow rate of 1.0 ml/min,the detection wavelength was 360 nm,and column temperature was 35 ℃. RESULTS:The linear range was 0.416-12.48 μg for hyperoside (r=0.999 9),0.14-4.2 μg for rutin (r=0.999 9),0.185-5.55 μg for quercetin (r=0.999 9) and 0.078-2.34 μg (r=0.999 8);RSDs of precision,stability and reproducibility tests were lower than 3%;recoveries were 95.55%-99.74%(RSD=2.12%,n=6),95.96%-101.42%(RSD=2.01%,n=6),95.76%-102.75%(RSD=2.77%,n=6), 99.42%-104.93%(RSD=2.02%,n=6). The flavonoids in salt-processed C. chinensis showed highest contents when baking tem-perature was 160℃,baking time was 60 min and moistening time was 2 h.

Objective To observe the final adult height of 20 boys with idiopathic central precocious puberty (ICPP) treated with slow-releasing gonadotropin-releasing hormone analogue(GnRHa).Methods Twenty boys with ICPP were treated with GnRHa for( 20.0 ± 6.1 ) months.At the beginning of therapy,mean chronological age and bone age was( 11.4 ± 1.0 ) years and ( 13.0 ± 0.4 ) years,respectively,GnRHa was discontinued when the boys reached the chronological age and bone age of( 13.2 ± 1.1 ) years and ( 13.7 ± 0.6 ) years,respectively.After the end of treatment,all the boys had been followed up for( 3.3 ± 1.5 ) years and had achieved adult height.Comparisons were made among their predicted adult height ( PAH ),final adult height ( FAH ),and target height ( THt ).The long-term outcome of final adult height in boys with ICPP was investigated after GnRHa treatment.Results All the boys reached target height range.Final height was similar to the target height [ ( 169.8 ± 5.8 vs 167.8 ± 4.6 ) cm,P＞0.05 ].The height gain,defined as the difference between predicted adult height at the start of treatment using the height SDS for bone age and actual adult height was( 3.62 ± 3.57 ) cm with the residual growth capacity of ( 11.82 ±3.99)cm,PAH significantly improved after GnRHa treatment compared with before treatment [ ( 169.0 ± 5.0 vs166.2 ± 4.2 ) cm,P＜0.01 ].There were no differences among PAH,FAH,and THt.Conclusion GnRHa treatment improves final height within the range of target height in boys with central precocious puberty.

Forty girls with Turner's syndrome (TS),aged (12.6 ± 1.9) years,were treated with daily subcutaneous injection of recombinant human growth hormone (rhGH,1.0 ～ 1.1 IU · kg-1 · w-1) and oral stanozolol (0.02 ～ 0.04 mg · kg-1 · d-1) for 1 ～ 5 years.Growth velocity (GV),height standard deviation score (SDS) by reference of healthy Chinese girls (HtSDSNor) and height SDS by reference of untreated Chinese TS girls (HtSDSTs)were evaluated regularly.Of the forty girls studied,thirteen had discontinued the treatment after a mean duration of (2.9 ± 1.2)years when GV was less than 2 cm/year or when patients were satisfied with the achieved height.Final adult height (FAH) or near-final height,which was defined as the most recent available height after discontinuation of treatment,and the height gained in the thirteen girls were evaluated.Estrogen therapy was started at the age of(16.0 ± 1.1) years.HtSDSNor increased from-4.2 ± 1.0 to-3.4 ± 1.0 in the first year,and-2.8 ± 1.0,-2.4 ± 0.8,-2.5 ± 0.5,-2.3 ±0.3 respectively in the 2nd,3rd,4th,and 5th year.The change in HtSDSTs was similar to HtSDSNor.It was increased from 0.1 ± 0.9 to 1.0 ± 0.9 in the first year,and to 1.5 ± 0.8,1.9 ± 0.6,1.7 ± 0.4,1.7 ± 0.2 in the subsequent 4 years.The predicted adult height (PAH) in 13 girls was (142.8 ± 4.2) cm before treatment.FAH was (151.7 ± 4.1) cm,which was significantly higher than PAH (P＜0.01),and the mean height gain was (8.9 ± 2.8) cm (5.1 ～ 12 cm).FAHSDSNor was increased to-1.6 ± 0.8 from-3.8 ± 0.8.For girls with TS around 9 years of age,combined therapy with rhGH and low dosage of stanazolol may significantly increase growth velocity and improve final adult height.

Objective To assess the efficacy and impact factors of treatment with Gonadotropin-releasing hormone analogs (GnRHa) in central precocious puberty (CPP) or early and fast puberty (EFP) girls in a retrospective unicenter study.Methods One hundred and two girls (75 CPP and 27 EFP) were treated with GnRHa alone and were followed up to their final adult hight (FAH).Results FAH was (158.0 ± 4.8) cm,being significantly higher than pretreatment predicted adult height [(151.1 ±5.1) cm,P＜0.01].There was no significant difference between CPP [(7.3 ± 4.4) cm] and EFP [(5.5 ± 4.5) cm] in net height gain.There was no significant improvement in FAH and pretreatment PAH for the patients who had menarche before treatment or whose growth velocity was less than 4 cm during the first year.Conclusion GnRHa treatment improves FAH efficiently for both CPP and EFP girls.Nevertheless,those who had menarche before treatment or whose growth velocity was less than 4 cm during the first year can hardly improve FAH by GnRHa treatment alone.

Objective To study the immune system regulatory effects of CD8+CD28-regulatory T lymphocytes in an experimental bone marrow mesenchymal stem cell treatment of autoimmune encephalomyelitis.Methods A model of autoimmune encephalomyelitis (EAE) was established in twenty-eight C57BL/6 female mice,6 to 8 weeks old weighing 16 to 20 g using myelinoligodendrocyte glycoprotein 35-55 amino acid peptide (MOG35-55).The mice were randomly divided into a phosphate-buffered solution (PBS) group (n =7),an MSCs-Low group [n =7 which received an injection of 2× 105 mesenchymal stem cells (MSCs)],an MSCs-Med group (n=7,1× 106 MSCs),and an MSCs-High group (n=7,5×106 MSCs).Their clinical condition was then evaluated daily.On the 15th day after the MOG35-55 immunization,the different MSC doses were administered intravenously via the tail.On the 30th day the mice were sacrificed to observe any neuropathology of the spinal cord.At the same time,FACS flow cytometry was used to assay CD8+CD28-T cells in the spleen.Results Compared with the PBS control group,the MSC treatment effectively alleviated illness among the mice by the 15th day after the immunization.The maximum and average disease scores and clinical illness scores had all improved significantly.The medium dosage worked best.Neuropathological analysis showed that the MSC treatment could significantly reduce the invasion of inflammatory cells and minimize demyelination in the spinal cord.Furthermore,the CD8+ CD28-regulatory T cells in the spleens of the MSCtreated animals increased compared with the PBS control group,though the secreted levels of IL-10 showed no obvious difference.Conclusions Treatment with MCSs can promote the recovery of neural function in autoimmune encephalomyelitis,at least in mice.CD8+CD28-regulatory T cells may not be the main effector cells,playing only a synergistic therapeutic role.
