Objective To evaluate the laparoscopic repair for indirect inguinal hernia in children. Methods A total of 72 children with unilateral and 25 children with bilateral indirect inguinal hernia underwent laparoscopic high ligation of the sac. In operation a self-made needle introduced subperitoneally was used to pass a ligature circumferentially around the internal ring. Results All the operations were successfully completed. The average operating time was 10 min in unilateral hernias and 16 min in bilateral hernias. The postoperative hospital stay was 1 day. No surgical complications occurred. Follow-up for 2~60 months (mean, 31 months) in 70 children found no recurrence. Conclusions Laparoscopic repair for indirect inguinal hernia in children is safe, feasible and minimally invasive, offering a low complication and recurrence rate and a quick postoperative recovery.

Objective To study the value of sequential duodenoscopic-laparoscopic treatment in patients with cholelithiasis. Methods Clinical data of 2 248 cases of cholelithiasis treated with sequential duodenoscopic-laparoscopic plan from January 2000 to December 2004 were retrospectively reviewed. Results Duodenoscopy indicated the confirmative diagnosis of gallbladder stones in 1 817 cases and gallbladder stones with associated common bile duct stones in 431 cases. Among 2 021 cases diagnosed as having gallbladder stones by B-ultrasonography: endoscopic retrograde cholangiopancreatography (ERCP) was performed in 690 cases, 213 of which were found having associated common bile duct stones; intraoperative cholangiography (IOC) was conducted in 85 cases, 10 of which were found presenting common bile duct stones; residual stones in the common bile duct after laparoscopic cholecystectomy (LC) were noted in 6 cases which were cured by endoscopic sphincterotomy (EST). Among 227 cases diagnosed as having gallbladder stones combined with common bile duct stones by B-ultrasonography, the diagnosis of common bile duct stones were confirmed by ERCP in 202 cases. Out of the 2 248 cases, 1 817 cases underwent the LC, 395 cases received EST and LC, and 36 cases were given the laparoscopic bile duct exploration (LBDE) (the bile duct was closed by primary suture in 26 cases and a T-tube was left in the bile duct in 10 cases). The 6 cases of residual stones in the bile duct were cured with EST postoperatively. A total of 28 cases required a conversion to open surgery (1.2%), and complications occurred in 52 cases (2.3%). Conclusions Sequential duodenoscopic- laparoscopic treatment for cholelithiasis offers a low residual stone rate and a high success rate.

Object To develop a new method of discriminating the principle components of Radix Paeoniae Rubra (RPR) from different areas, and to find the reason for forming high-quality of RPR in the place of the genuine. Methods Using Foruier transform infrared (FTIR) absorption spectrometry, the characteristic peaks of fingerprint infrared spectra of RPR samples from 18 habitats were recognized and compared. Results Frequency, intensity and shape of infrared absorption spectra were obviously different between wild and cultivated groups of RPR. The infrared absorption peaks of RPR in Duolun, a famous Chinese orthodox drug, were of distinct characteristics. Conclusion FTIR technique is first applied to rapid analysis of principle component of RPR from different areas. So an operable method in the quality control and discrimination of RPR in the place of the genuine is provided.

The geo-herbalism of Cangzhu, Atractylodes lancea (Thunb.) DC. , was studied for itsstrict quality control. Samples of typical and representative populations of geo-herbal and non-geo herbalorigin were collected, examined and cultivated through field work. Volatile oils from samples of varioushabitats were determined by GC/MS, and their respective bacteriostatic minimum inhibitory concentration(MIC)determined. Results of the study showed that both the size of capitulum and cleft on the leaves var-ied greatly even in species of the same population. The main components in their volatile oil also variedgreatly with Maocangzhu (MCZ) contains atractylone (29.54%) and atractylodin (17.82%); that of Nan-cangzhu (NCZ) contains hinesol (61.86%) and β-eudesmol (19.79%), and Baicangzhu (BCZ) cantains βeudesmol or mixture of β-eudesmol and atractylone (over 30%). Volatile oils of speciaes from Luotina,Taibai, and Huanglong showed potent bacteriostatic activity against Streptococcus hemolyticus (SH), com-parable to penicillin or streptomycin. In conclusion, A. lancea is a polymorphic complex greatly influencedby geographic environment and a reasonable proposal is to name them by geo-herbal names such as: MCZas A. lancea var. maoshanensis Hu et Feng; NCZ as A. lancea subsp. luotianensis Hu et Feng; and BCZ asA. lancea var. chinensis (Bunge) Kitam other than independent species as A. chinensis Bunge. It was in-correct to say that MCZ has no atractylone in its volatile oil and therefore differs from A. macrocephalaKoidz. (Baizhu). Inhibitory activity of the volatile oils against SH and Pseudomonas aeruginosa (PA) arealso quite different due to the habitats and imply that the rhizome from Luotian may be used to cure infec-tion diseases caused by SH and PA besides their traditional uses.

ObjectiveTo evaluate the value of inferior petrosal sinus sampling (IPSS) in the diagnosis of adreno-corticotropic hormone ( ACTH ) dependent Cushing syndrome ( CS ) with unknown origin. MethodsIPSS was carried out for the diagnosis of 16 cases with ACTH dependent CS who had not been identified after a series of dexamethasone suppression tests and radiological examinations. The ratio of inferior petrosal sinus/peripheral ACTH was assayed.The sensitivity and specificity of diagnosis of the Cushing disease were estimated. ResultsThe inferior petrosal sinus/peripheral ACTH ratio was over 2. 0 in 13 cases. Twelve cases underwent surgery with pathological diagnosis of pituitary ACTH adenoma, 1 patient relieved after γ knife treatment. The ratio was < 2.0 in 3 cases including 2 pulmonary carcinoid and one pituitary ACTH adenoma. The sensitivity and specify of IPSS for the diagnosis of Cushing disease were 13/14and 2/2 respectively.ConclusionIPSS was a safe technique with high sensitivity, specify and infrequent complications in the diagnosis of ACTH dependent Cushing disease.It had great clinical value in the differential diagnosis of ACTH dependent Cushing disease with unknown origin.

BACKGROUND: Lentivirus can infect divided and undivided cells. It remains uncertain whether the lentivirus can successful y infect primary ovarian granulosa cells. OBJECTIVE: To investigate infecting ratio and cel apoptosis of lentivirus carrying bcl-2 gene in primary human ovarian granulose cells cultured in vitro. METHODS: The lentiviral vector carrying bcl-2 gene was constructed using molecular biology, and packaged into lentivirus with high titer. The resulting recombinant lentivirus carrying bcl-2 genes were then used to infect primary human ovarian granulosa cells in vitro at different multiplicity of infection, 10, 50, 100, 200, and 400. Infection efficiency and cel proliferation were observed at 24, 48, 72, and 96 hours fol owing infection. Cel apoptosis was detected by flow cytometry, and bcl-2 gene transcription was assessed using reverse transcription PCR. RESULTS AND CONCLUSION: Primary human ovarian granulosa cells adhered at 24 hours, and exhibited polygon- or fusiform-shape and colony-like growth. When multiplicity of infection was 100, cel appearance and growth remained unchanged, and infection efficiency was high, which reached the peak up to 72 hours. Moreover, the positive rate was up to 60% in granulosa cells. Lentivirus carrying bcl-2 gene could increase expression of Bcl-2 protein and inhibit apoptosis of primary ovarian granulosa cells.

Objective To investigate the clinical value of GFR, microalbuminuria (mAlb), serum β2-microglobulin (MG) and cystatin C (CysC) for the evaluation of renal function in patients with DN.Methods A total of 150 patients with type 2 DM diagnosed by WHO standard (1999) from December 2012 to December 2015 were retrospectively analyzed.Thirty-three kidney transplantation donors during the same time were chosen as the control group.The urine mAlb, Cr, albumin/Cr ratio(ACR) and SCr, serum β2-MG, CysC, urea, uric acid(UA), fasting blood glucose (FBG), hemoglobin A lc (HbA1c) and C-reactive protein (CRP) were measured.99Tcm-DTPA renal dynamic imaging was performed.The Gates method was used to calculate GFR, and the modification of diet in renal disease (MDRD) method was used to calculate the estimated GFR (eGFR).The relative equation between GFR and eGFR was studied.The clinical stages of renal function in type 2 DM patients were evaluated by Mogenesen standard method.Two-sample t test was used for data analysis.ROC curve analysis was performed to study the diagnostic value of GFR in DN.Results The patients were divided into merely type 2 DM group, early stage DN (Ⅰ, Ⅱ, Ⅲ), and clinical DN(Ⅳ) groups by Mogenesen standard method.GFR and eGFR in the DNⅠstage were higher than those of the merely type 2 DM group (t values:-7.502,-3.629, both P<0.01), and GFR and eGFR decreased with the increased stage of DN.However, serum UA, CRP, FBG and HbA1c, SCr, urea, β2-MG, CysC, mAlb and ACR increased when the stage of DN was higher.GFR and eGFR showed a linear correlation, with the regression equation of y=0.957x+6.823.AUC of ROC in patients with DN Ⅰ was 0.989.With the cutoff value of 125.09 ml/min, the sensitivity and specificity was 96.2%(25/26) and 98.4%(122/124) respectively in diagnosis of DNⅠ.Between high UA and normal UA groups, FBG and HbA1c were not significantly different (t values:-1.010,-1.034, both P>0.05), but the renal function indicators were different (t values:-5.090-2.209, all P<0.01).Compared with the normal CRP group, the FBG, HbA1c and renal function indicators were statistically different in high CRP group (t values:-6.114-7.386, all P<0.01).Conclusions GFR and eGFR show a linear relationship in type 2 DM.GFR is a sensitive, specific diagnostic index in DN Ⅰ period.β2-MG, CysC, mAlb and ACR are conducive to the early diagnosis of DN.High UA is an independent risk factor for the onset of DN, and high CRP is an inflammatory damage factor in DN.
