[Objective] To explore the best method for sequelae neuralgia of herpes zoster.[Method] Randomly divide the said patients into groups treated with external application of Chinese drugs and sky moxibustion,make observation and comparison between them.[Result] Both got high late curative effect,however most patients in the sky moxibustion group were cured without recurrence,the pain relieving rate was high once being cured,the reduce of pain index was apparent after treatment,which was of statistical meaning compared with drug application group.[Conclusion] The sky moxibustion method combines drugs and moxibustion well and has marked advantages in treating herpes zoster,worth of promotion and application.

0.05).The lobular sign was markedly more in peripheral pulmonary squamous carcinoma than in other histopathological group(P0.05).Conclusion There are certain relation between spiral CT appearance and histopathology in peripheral pulmonary carcinoma.CT appearance may be one of the evidence in diagnosing the histopathological type in peripheral pulmonary carcinoma.

Objective: To explore the clinical significance. Methods: The double-antibody sandwich ELISA technique. Result: The serum interleukin-6(IL-6) levels of patients with cholangiocarcinoma are significantly higher than those in benign biliary disease and normal controls (P<0.05). Conclusion: Serum IL-6 levels of patients with cholangiocarcinoma are significantly increased ,it is one of the important parameters for clinical evaluation in patients of cholangiocarcinoma.

Objective To observe the changes of cardiac rhythms in a swine model of adult asphyxia! cardiac arrest. Method Sixteen Pigs were aphyxiated by endotracheal tube clamping until 8 min after loss of aortic pulsations. Resuscitation was then provided and swinds were assigned to received 0.045 mg/kg epinephrine intravenously after 3 min of basic life support. The animals with restoration of spontaneous circulation within 20 min from CPR were defined as successfully resuscitated, while the rest were identified as unresuscitation. Electrocardiogram ( EGG) were monitored from the start of asphyxia to the start of the CPR. Results When loss of pulsations occurred, 2 of 16 animals had ventricular fibrillation; 10 pigs exhibited pulseless electrical activity, and 4 pigs had asystole. During the 8 min after the loss of aortic pulsations, pulseless electrical activity converted to VF in 7 pigs. Immidiatedly prior to resuscitation, VF occurred in 9 pigs, asystole in 4 pigs, and PEA in 3 pigs. Conclusions Most of animals in this swine model of asphyxial cardiac arrest presented PEA, but most of them converted to VF especially late in the asphyxial process.

Objective To investigate the timing of operation and the selection of surgical procedure for acute biliary pancreatitis.Methods The clinical data of 247 cases of acute biliary pancreatitis were retrospectively analysed.Results Among 10 non-operation patients,4 died;12 patients underwent emergency operation,5 had postoperative complications and 2 patients died after operation.169 patients underwent delayed operation after effective conservative therapy and 1 patient had postoperative complication;56 patients underwent(selective) operation without any postoperative complication or death.Conclusions Early emergency operation should be performed for relief of biliary obstruction in acute biliary obstructive pancreatitis.The patients with acute non-obstructive biliary pancreatitis should undergo conservative therapy at first and then,after(pancreatitis) has been controlled,delayed operation or selective operation to treat the biliary pathologic condition should be performed.

Objective To evaluate the diagnostic and therapeutic methods for hilar bile duct carcinoma. Methods The clinical data of 36 patients with hilar bile duct carcinoma from Jan 1998 to Jul 2003 were retrospectively analyzed. Results The misdiagnosis rate(39%) was high. All patients underwent a surgery. The median survival time of 16 patients treated by radical resection was 30 months. The 1,3,5-year survival rate was 93%,50% and 25% respectively. While the median survival time of the rest 20 patients treated by a variety of non-radical operation was 16 months with 1,3,5-year survival rate of 47%,8% and 0 respectively(t=2.585).Conclusions Early diagnosis and radical resection improves long-term survival of patients with hilar bile duct carcinoma.

Objective To investigate the preventive effects of 103 Pd radioactive stent on stenosis after bile duct injury in dogs.Methods Twelve healthy dogs (15～20kg) were randomly divided into 103 Pd radioactive stent group (n=6) and control group (n=6). Immediately after balloon dilatation injury to the bile duct, the 103 Pd radioactive stent(experiment group) or the ordinary stent(control group) was positioned into the target segment. The dogs were killed one month later. The injured bile duct segments were dissected free from the dogs, and were examined radionucleonically, immunohistochemically and pathologically. Muscular proliferation area and lumen area were determined by computer assisted picture analysis system. Results In the control group, 30 days after ductal injury, the mucosa of the bile duct was fractured, the mucosa was proliferated and the lumen stenosed.Compared with the control group, 103 Pd radioactive stent significantly reduced muscular proliferation area (P

The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed, including those on their inhibition activities of coagulation factor Xa (FXa) and thrombin (FIIa). The results showed that the anti-FXa and -FIIa activities of enoxaparins with different degree of 1,6-anhydro derivatives (20.0%-39.7%) with similar structure characteristics, had decreasing tendency when the degree of 1,6-anhydro derivatives increased. Especially, the anti-FXa activity was sensitive to the change of the degree of 1,6-anhydro derivatives.

Objective To study the effect of soluble, refolded, recombinant extracellular domain of the human Fc gamma receptor Ⅱ a (huFcγRⅡa) on the binding of human IgG to cells. Methods Extra-cellular domain of the huFcγRⅡ a gene was amplified from recombinant plasmid pe3huR Ⅱ by PCR and then cloned into pET-28a vector. The recombinant plasmid pETshuR Ⅱ was transformed into E. coli BL21 (DE3) after identified by PCR and doubly digested. The inclusion bodies of fusion protein were extracted and purified by washing, dissolved in 6 mol/L guanidine buffer, and refolded by rapid dilution technique. The refolding protein activity was tested by ELISA and flow cytometry. Results Extraceilular domain of the huFcγRⅡa gene was successfully cloned into pET-28a. The results of SDS-PAGE showed that the molecular mass (Mr) of the expressed protein was 24.8 × 103, and the expression rate was 30%. The purity of recom-binant shuR Ⅱ was up to 90% after washing. ELISA showed that the recombinant shuR Ⅱ was able to bind human IgG in a dose dependent manner, shuRⅡ could competitively inhibit the binding of human IgG to huFcγRⅡa expressed on the surface of COS-7 cells by flow cytometry. Conclusion The results demon-strate that it is possible to obtain large quantities of recombinant shuR Ⅱ which has comparable binding prep-erties to those of the whole membrane bound huFcγR Ⅱ a.

Objective To investigate the mechanism and role of ?-ray of 103Pd in the treatment of biliary duct cancer.Methods A series of biliary duct cancer cells were treated with different ?-ray dose,and MTT [3-(4,5-dimethy thiazol-2-yl)-2,5-diphenyl terazolium-bromide] technique was used to determine the inhibition rate of ?-ray of 103Pd on the biliary duct cancer cells;and electron micro-technique,DNA agarose gel electrophoresis and flow cytometry to evaluate the morphological characteristics and apoptosis rate of the biliary duct cancer cells were also used.Results The ?-ray radiation of 103Pd resulted in significant inhibition of the biliary duct cancer cells.The features of biliary duct cancer cells apoptosis(e,g:apoptic bodies,DNA ladders band hypodiploid DNA peak) could be seen in the group with lower dosage(5.333mci),and cell necrosis was seen in higher dosage(more than 6.645 mci).Conclusions The ?-ray radiation could induce apoptosis of the biliary duct cancer cells,but with dose dependence,and apoptosis can be an important mechanism for radiation treatment of biliary duct cancer.
