Objective To explore the value of laparoscopic diagnosis and treatment for Meckel’s diverticulum in children. Methods Laparoscopic exploration was performed in 11 children with suspected intestinal Meckel’s diverticulum. In other 2 children, the diverticulum was encountered during laparoscopic appendectomy, and then the umbilical incision was prolonged to take out the corresponding intestine for resection. Results No conversions to laparotomy were required in all the 13 children. The operation time lasted 30~90 min (mean, 75 min). The children were discharged at 5~6 postoperative days without complications. Conclusions Laparoscopic diagnosis and treatment for Meckel’s diverticulum in children is effective.

[Objective] To observe the effects of regulating Qi and strengthening spleen on the patients of chronic ulcerative colitis.[Methods] 38 patients of chronic ulcerative colitis(UC)were randomized and divided into experiment group(20 patients)and control group(18 patients)according to the selected standard.The patients of experiment group were treated with complex prescription of regulating Qi and strengthening spleen,the patients of control group were treated with granules of Mesalazine.To observe the symptom of accumulated points and enteroscope appearance on two groups.[Results] The difference on the symptom of accumulated points of experiment group exceeded the control group(P0.05).[Conclusion] There is effect of regulating Qi and strengthening spleen on the patients of chronic UC.

Objective To investigate the mechanism of treatment of lung cancer with Bacillus Calmette-Guerin Polysaccharides nucleic acid (BCG-PSN) combined with Cyclophosphamide(Cy). Methods 130 mice were divided into three groups (A,B and C groups). Gruop A was further divided into four subgroups . Subgroup A-1 was given normal saline orally 0.25mg/10g?d -1 ; Subgroup A-2 was given levomisole PO. 0.25mg/10g?d -1 ; Subgroup A-3 was given BCG-PSN PO.0.325mg/10g?d -1 and subgroup A-4 was given BCG-PSN by intra-abdominal injection 0.25mg/10g?d -1 . Group B was given identical drugs with group A, after fifth day given 20% sheep red blood cell 0.2ml by intra-abdominal injection for five days . Gruop C divided into five subgroups;Subgroup C1-4 were given same drugs with group A,then given 0.4% Cy by subcutaneous injection 0.25mg/10g?d -1 from fifth day to tenth day.Subgroup C-5 was normal contral group, was given normal saline 0.25mg/10g?d -1 PO and subcutaneous injection 0.25mg/10g?d -1 .Results Oral administration alone or intra-abdominal injection in subgroup A-4 obviously enhanced the phagocytosis of macrophages.The subcutaneous injection of Cy could obviously decrease anti-tumour immunity, including activity of interleukin-2 (IL-2),natural killer(NK) cell, lyphocyte trasformation, and macrophages phagocytosis. BCG-PSN could increase and rehabilitate above anti-tumour immunological function. Conclusions Combinative treatment of BCG-PSN with Cy could remarkable enhance the immunocompetence.This experiment may provide a theoretical evidence for BCG-PSN combined with chemotheapeutic agents applied to treat the lung cancer.

Objective To review the experience of minimally invasive incision for open-heart surgery in 56 children with congenital heart diseases.Methods There were secundum atrial septal defect (ASD)25 cases, ventrilcular septal defect (VSD) 26 cases, double-chambered right ventricle (DCRV) 2 cases and pulmonary arterial stenosis (PS) 3 cases,right anterior-lateral thoracotomy for 23 cases in heart beat CPB and ministernotomy for 33 cases participated in the study.Results No death or serious complications happened,and the patients' postoperative recovery rapidly,mean hospital stay was 8 days .Conclusions Minimally invasive incision has followe as advantages,such as :less trauma, cosmetic, less pain, recovery rapid, safeness, effectiveness, and shorter hospital stay,especially for repairing the secundum atrial septal defect, membranous or para-membranous ventrilcular septal defect.

Objective: To establish the fingerprint chromatogram of Tongguanteng Injection (caulis Marsdeniae Tenacissimae). Methods: HPLC with ZORBAX SB C 18 column was used, the (a) 0.05% H 3PO 4 H 2O and (b) ACN 0.05% H 3PO 4 H 2O (13∶87) (gradient elution) as a mobile phase and detection wavelength at 254nm. Results: 22 peaks were indicated on the HPLC fingerprint of Tongguanteng Injection. The relative retention time and relative peak area were obtained with itself peak at retention time 48.5 min. Conclusion: The method is simple and accurate with a good reproducibility and can be used as a quality control method for Tongguantent Injection.

OBJECTIVE:To establish a method for simultaneous determination of valsartan and hydrochlorothiazide in Valsar-tan hydrochlorothiazide tablets. METHODS:UPLC was adopted. The determination was performed on Phenomenex C18 column with mobile phase consisted of [0.1% phosphoric acid solution-acetonitrile(95 : 5,V/V)]-[0.1% phosphoric acid solution-acetonitrile (5 : 95,V/V)](gradient elution)at the flow rate of 0.25 mL/min. The detection wavelength was set at 272 nm,and the column tem-perature was 35 ℃. The sample size was 1.5 μL. RESULTS:The linear range were 8.1-324.2 μg/mL for valsartan(r=0.9999)and 1.2-50.1 μg/mL for hydrochlorothiazide(r=0.9999). The limits of quantitation were 0.24,0.04 ng,and the limits of detection were 0.06,0.01 ng. RSDs of precision,stability and reproducibility tests were less than 2.0%;recoveries were 97.69%-100.35%for valsartan(RSD=1.03%,n=9)and 98.27%-100.60% for hydrochlorothiazide(RSD=0.83%,n=9). CONCLUSIONS:The method is simple,rapid and accurate,and can be used for the simultaneous determination of valsartan and hydrochlorothiazide in Valsartan hydrochlorothiazide tablets.

Objective To investigate the effects of C-terminal fragment of parathyroid hormonerelated protein (PTHrP107-139) on bone mineral density (BMD), bone histomorphometry and biomechanical properties in ovariectomized (OVX) rats and its effect on bone metabolism is also explored. Methods Forty 4-month old female Wistar rats in which 30 were ovariectomized and then divided into 3 groups: the placebo, the PTHrPC and the CT groups, the other 10 rats were Sham-operated as the control group (Sham). Five weeks later, the rats of PTHrPC and CT groups were subcutaneously injected with PTHrP107-139 (40 μg/kg) and Salmon Calcitonin (15 U/kg) respectively once every other day. The rats of the placebo and sham groups were injected with 0.2 ml saline once every other day. After treatment of 12 weeks, all rats were sacrificed and all samples were collected and analyzed. Results ① Compared with the placebo, the BMD and bone strength of PTHrPC and CT groups were significantly increased (P<0.05). ② Histomorphometry revealed that the tetracycline labeled bone surfaces, osteoid surfaces, mineral apposition rate and bone resorption rate were remarkably decreased in PTHrPC, and CT groups comparing with those of the placebo group. Conclusion Cter-minal PTHrP107-139 is effective in increasing the BMD, bone strength and quality when administered intermittently to ovariectomy-induced osteoporotic rats. Its increasing in bone quality may relate to reducing bone turnover and inhibiting resorption.
