Objective To study the effect of CO2 pneumoperitoneum on the anti-apoptotic capability of human cervical carcinoma cell line(CaSki).Methods The imitated CO2 pneumoperitoneum was established in vitro.After CaSki cells were exposed to CO2 pneumoperitoneum at 0,7 or 14 mmHg for 1,2,3,4 h,the expressions of Survivin mRNA and Bcl-2 protein were examined by RT-PCR and Western blot respectively.The untreated CaSki cells served as control.Results Under 7 or 14 mmHg,the expressions of Survivn and Bcl-2 had an increasing tendency with the exposure time prolongation.Within the same exposure time,the expressions of Survivin and Bcl-2 under 7 mmHg were significantly higher than those under 0 or 14 mmHg or in control group.Conclusion Under certain pressure and within certain exposure time,CO2 pneumoperitoneum could improve anti-apoptotic capability of human cervical carcinoma cells,which may be one reason for the promoting effect of carbon dioxide pneumoperitoneum on malignant cells growth.

Objective To investigate the dose-respeuse relationship of levobupivacaine for spinal anesthesia in patients undergoing cesarean section.Methods Sixty ASA Ⅰ or Ⅱ patients aged 25-35 yr weighing 60-90 kg scheduled for elective cesarean section under spinal anesthesia were enrolled in this study.Spinal puncture was performed at the L3,4 interspace.A 25 G spinal needle was inserted into the subarachnoid space cephalad.The patients were randomized to receive levobupivacaine 7.5 mg (group L1 ),10 mg (group L2),12.5 mg (group L3) or 15 mg (group L4) diluted to 3 ml with 5% glucose over 30 s (n = 15 each).The degree of pain was evaluated at the time of skin incision using visual analogue scales (VAS) (0 = no pain and 10 = worse pain ever).Effective analgesia was defined as VAS = 0.Spinal analgesia was inadequate when VAS≥1 and then 1% lidocaine 5-10 ml was given epidurally.The doses of levobupivacaine for effective analgesia in 50% and 95% of patients ( ED50 and ED95 ) and 95 % confidence interval were calculated by Probit method.Results The ED50 of levobupivacaine was 9.0 mg (95% confidence interval 7.8-9.9 mg) and ED95 13.2 mg (95% confidence interval 11.6-17.6 mg) for spinal anesthesia.Conclusion The ED50 and ED95 of levobupivacaine for spinal anesthesia in patients undergoing cesarean section are 9.0 mg and 13.2 mg respectively.

OBJECTIVE:To provide reference for imipenem-resistant Pseudomonas aeruginosa infection control. METHODS:114 patients infected with imipenem-resistant P. aeruginosa were selected from 3 tertiary hospitals in Zhoushan during Feb. 2013 to Feb. 2014. 114 strains of P. aeruginosa were isolated from clinical specimens,and drug resistance characteristics and carbapene-mase-producing gene diversity were analyzed. 101 inpatients with imipenem-resistant P. aeruginosa infection were included in con-trol group;univariate and multivariate Logistic regression analysis were adopted to explore the risk factors of imipenem-resistant P. aeruginosa infection. RESULTS:114 strains were sensitive to polymyxin B,and had different levels of resistance to other 9 kinds of antibiotics. Carbapenemase-producing gene were mainly IMP and VIM type gene. Long-term hospitalization,mechanical ventila-tion,used imipenem and early combined use of antibiotics were risk factors of imipenem-resistant P. aeruginosa infection. CON-CLUSIONS:In Zhoushan area,imipenem-resistant P. aeruginosa shows serious drug resistance. To avoid long-term hospitalization and early combined use of antibiotics can reduce imipenem-resistant P. aeruginosa infection.

METHODS: The mice were infected separately by Ⅰ、Ⅱ type flu virus,staphylococcus aureus or pneumococcus in the experiment.The protective action of Qinzhi Capsule on them was observed in vivo.and detemined mininum inhibition concettation(MIC). RESULTS: Qinzhi Capsule could prolong markedly the survival periods of mice(P

AIM: To study the anti-inflammatory,analgesic and antipyretic effects of Qinzhi Capsule(Radix Scutellariae,Fructus Gardeniae,etc).

RESULTS: Qinzhi Capsule could inhibit markedly the increase in abdomen capillary permeability in mouse induced by acetic acid(P

AIM: To determine the suitable condition and the optimal parameters for the extraction and purifiction process of total flavonoid compounds in Scutellaria baicalensis. METHODS: It was investigated by orthogonal experiment design of form L_9(3~4) with the extraction percentage of the total flavonoid compounds and baicalin from Scutellaria baicalensis as the standard. RESULTS: The optimal condition of extraction was with water as much as ten times of the medicine amount and was boiled for 2 h and three times,and the optimal condition of purifiction was as follows: solution concentration 0.25 g(crude medicinal materials) /mL,adjusting pH to 2,80 ℃ heat preservation up to 60 min, 50% alcohol as precipitant and the precipitated adjusted pH to 4.0. CONCLUSIONS: The optimal process is rational,practical and adapted to industry production.

Objective To analyze the causes and preventions of the perioperative complications of micro-laparoscopic hernioplasty in infants and children with indirect inguinal hernia.Methods From January 1997 to January 2007,4500 infants or children with indirect inguinal hernia,including 702 cases who were complicated with hydrocele testis,were treated by micro-laparoscopic hernioplasty in our hospital.By laparoscopy,the endocycle was sutured circularly under the peritoneum using a self-designed needle.Then,only the peritoneum was ligated.Results No organ injury or complication occurred during the operation.The mean operation time was 9 min(5-13 min).Among the patients,4250 received a follow-up of 7-36 months(mean,25 months).Postoperative complications were found in 132 patients(3.1%),included scrotal gas in 10(0.24%),scrotal hydrocele in 16(0.38%),umbilical hernia in 27(0.64%),extraperitoneal emphysema in 20(0.47%),abdominal wall hematoma at the burr hole in 15(0.35%),foreign body sensation at the suture sites in 30(0.71%),scrotal hematoma in 8(0.19%),and iatrogenic cryptorchism in 6(0.14%).Thirty-five patients had recurrence(0.82%).Conclusions Micro-laparoscopic hernioplasty is a safe and reliable method for indirect inguinal hernia in infants and children.It is important to be familiar with the anatomy of the hernia under a laparoscope and to perform the operation carefully so that to avoid or decrease the perioperative complications.

Objective To evaluate the efficacy of mini-laparoscopic hernioplasty with Mesh strengthening in the treatment of hernia in adults. Methods We used mini-laparoscopic and self-decided needle-like instruments to perform 106 cases of Mesh replacement in addition to hernioplasty in treatment ot hernia in adults from January,1999 to Junuary,2001. Results Operation time ranged from 20min to 25min.Food-intake began in the operative day.No Complications occurred.The patient discharged 3d～4d after the operation.Following-up period lasting 5months to 2.5years showed no relapse occurred. Conclusions Mini-laparoscopic hernioplasty combined with Mesh strengthening is feasible in the treatment of hernia in adults.The method have the advantages ot mini-invasion,simple proccedures,shorter operation time and quicker recovery.

Objective To explore the clinical value of laparoscopy combined with radionuclide imaging in the diagnosis and treatment of pediatric gastrointestinal hemorrhage, especially for Meckel’s diverticulum and double intestine. Methods ~ 99m Tc~-pertechnetate abdominal scintigraphy was performed in 22 children with a history of recurrent hemafecia or melena in this hospital from December 1998 to December 2005. All the children were given a laparoscopic exploration. Results Among the 22 patients, scintigraphy showed positive findings in 18 patients and negative, 4 patients. The positive patients were all confirmatively diagnosed by laparoscopic surgery and pathological examinations, including Meckel’s diverticulum in 14 patients and duplications of alimentary tract in 4 patients. In the other 4 patients with negative results, no organic pathologic changes was identified by laparoscopy in 3 patients and Meckel’s diverticulum was found after laparoscopic exploration in 1 patient. Conclusions Radionuclide imaging is an important method in the diagnosis of gastrointestinal tract hemorrhage in children and provides scientific basis for surgical intervention. The combination of laparoscopy and radionuclide imaging not only has values in the diagnosis and treatment of pediatric gastrointestinal hemorrhage, but also minimizes the blindness and trauma of exploratory laparotomy.
