AIM: There are many active components of tonifying kidney to strengthen the bone in Kanggu Zengsheng capsule, but there are few reports about its effect in treating bone fracture. CR molybdenum target X-ray is often used in mammary gland examination and disease diagnosis. This study detected the callus density during fracture healing in rats by CR molybdenum target X-ray to explore the promoting effects of Kanggu Zengsheng capsule on fracture healing. METHODS: The experiment was performed at the Laboratory Centre of Second Hospital of Hebei Medical University from July 2005 to March 2006. Sixty Wistar rats with an equal amount of males and females, 170-200 g, aged 9-10 months were randomly divided into experimental group and control group (n =30). After the tibial fracture model was made, the rats in the experimental group were given 1 mL Kanggu Zengsheng capsule suspension, 14.00-15.75 mg for each, once daily, while the rats in the control group orally took matching normal saline (9 g/L) once daily. All animals were executed under anesthesia by batch on the 3rd, 10th, 17th, 24th, and 33rd days after the operation, separately. The diameter of callus was measured with vernier caliper. The values of callus density were calculated by image analysis system in the CR molybdenum target X-ray. RESULTS: Sixty rats were all included in the final analysis. The photo of CR molybdenum target X-ray showed clear bone lines, and bone and soft tissue were evident. During the process of fracture union, there were significant differences in callus density between the two groups (P

Objective To report our experiences in difficult laparoscopic cholecystectomy (LC). Methods The clinical data of 201 cases of difficult LC performed from March 2006 to December 2008 were analyzed retrospectively,and the surgical operation approaches were summarized. The cases included 107 patients with pyknotic conglutination around the gallbladder or gallbladder triangle area,38 patients with gallbladder neck stone,11 patients with suppuration or gangrene of the gallbladder,18 patients with atrophy of the gallbladder,and 17 patients with operation history in the upper abdomen. Results The LC was completed in 193 of the cases,the other 8 cases were converted to open surgery. The causes for conversion to open surgery included intractable bleeding at the gallbladder triangle in 3 patients,the gallbladder being covered by stomach,colon and duodenum in 1,gallbladder gangrene in 1,bile leakage resulted from slightly lacerations of the posterior wall at the confluence of the gallbladder and bile duct in 2,and frozen likeness of the gallbladder triangle in 1. The complications of LC included intestinal obstruction (1 case),pulmonary infection with respiratory dysfunction (1 case),and postoperative bleeding (1 cases). No extrahepatic bile duct injury and death occurred in this series. Conclusions For difficult LC,we must abide by the rules as follows: to dissect as far as possible adjoin to the gallbladder;to discriminate the tissues or organs before cutting it;to execute LC in combination with mute and acuminate dissection and antegrade and retrograde approach for resection;to make pneumoperitoneum through a small incision for patients with history of operations in the upper abdomen. Only obey the laparoscopic surgical principle and use correct surgical approaches,can we reduce the incidence rates of complications and conversion to open surgery.

OBJECTIVE:To observe the short-term efficacy and safety of nimesulide combined with ibuprofen in the treatment of pain. METHODS:84 patients with pain were randomly divided into observation group and control group. Control group was oral-ly given 0.3 g Ibuprofen sustained-release capsule,twice a day. Observation group was additionally given 100 mg Nimesulide cap-sule,twice a day. The treatment course for both groups was 7 d. Clinical efficacy,visual analogue (VAS) score,quality of life (QOL) score,coagulation indexes (prothrombin time,thrombin time,fibrinogen,activated partial thromboplastin time) before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observa-tion group was significantly higher than control group,the differences were statistically significant(P<0.05). Before treatment, there were no significant differences in the VAS score and QOL score between 2 groups(P>0.05). After treatment,VAS scores in 2 groups were significantly lower than before,and observation group was lower than control group,QOL scores were significantly higher than before,and observation group was higher than control group,the differences were statistically significant(P<0.05). And there were no significant differences in the coagulation indexes and incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:The short-term efficacy of ibuprofen combined with nimesulide is superior to ibuprofen alone in the treatment of pain,with similar short-term safety.

Objective To observe the protective effect of α-lipoic acid (LA) pretreatment on hypoxia/reoxyg-enation injury in vascular endothelial cells and preliminary explore its mechanism. Methods HUVEC were cultured intro and devided into control group,hypoxia/reoxygenation model group and LA group. Cell morphology was observed under inverted phase contrast microscope,cell viability was detected by MTT,total antioxidant capacity (TAOC),nitric oxide(NO),malondialdehyde (MDA),superoxide dismutase (SOD) activity or level were measured by various commercial kits respectively. Apoptosis of HUVEC in each group were detected by flow cytometry , cleaved caspase-3 level was measured by western blot. Results As compared to control group, the survival rate, TAOC, SOD, NO activity were significantly lower(P<0.05), and MDA level, apoptosis rate and apoptosis protein levels were significantly higher (P < 0.05) in model group. However,LA can increase the survival rate,TAOC, SOD,NO activity (P < 0.05),reduce MDA level and cell apoptosis (P < 0.05)in a dose dependent manner. Conclusion LA pretreatments provide protection against hypoxia/reoxygenation injury in HUVEC. LA exerts protective effects through inhibition of HUVEC apoptosis.
