Objective To summarize the technical measures in achieving the elimination of lymphatic filariasis in Tengzhou city. . Methods. To collect and analyze the materials on research and control of lymphatic filariasis in Tengzhou city during the disease elimination program over the 40 years.. Results . Following to the national criteria for the control and elimination of filariasis, efforts were made for epidemiological investigation, mass blood examination, and mass drug administration by taking diethylcarbamazine (DEC) medicated salt for the whole population. After the criteria of transmission interruption (basic elimination) of filariasis were met in 1974, re-examination and treatment for the cases with microfilaremia, and parasitological and entomological surveillance were conducted. In 1995, filariasis elimination in the whole city was declared. . Conclusion . Comprehensive measures focusing on the elimination of source of infection were proved effective for interrupting the transmission of filariasis. Unremitting surveillance was necessary for achieving the goal of elimination of filariasis.

Objective To investigate the effects of nitric oxide (NO) and cholecystokinin (CCK) on the regulation of the motility of sphincter of Oddi (SO).Methods The basal pressure,action rate and contraction range of the SO were examined before and after the injection of CCK,sodium nitroprusside (SNP) and NG-nitroL-argininemethyl ester hydrochloride (L-NAME).The expression of neurons with positive expression of NO synthase was detected by immunohistochemical staining.The measurement data were analyzed by using the t test.Results The basal pressure,contraction rate and contraction range of the SO were (27 + 10)mm Hg (1 mm Hg =0.133 kPa),( 10 ± 3 ) times/minute and (32 + 8 ) mm Hg before injection of CCK,and (61 + 14) mm Hg,(64 +21 ) times/minute,(44 ± 15 ) mm Hg after injection of CCK of 20 ng/kg.After injection of CCK of 100 ng/kg,the basal pressure,contraction range and contraction rate of the SO were (77 ± 31 )mm Hg,(69 ± 18 ) times/minutes,(79 + 14) mm Hg when the inhibition effect of CCK reached peak,and were ( 140 ± 21 ) mm Hg,( 129 ± 25 )times/minutes,( 173 ± 63 ) mm Hg when the excitatory effect of CCK reached peak.After injection of SNP into the common bile duct,the basal pressure,contraction range and contraction rate of the SO decreased significantly ( t =3.706,5.183,P ＜ 0.05),while the 3 indexes increased significantly after injection of SNP (t =5.859,3.588,P ＜O.05).Conclusion Different from physiological dose (20 ng/kg) of CCK,large dose of CCK enhances motility of SO intensively.NO relaxes SO,which may play an important role in the inhibitor pathway of CCK.

Objective: To study the reasons and prevention of residual stones after choledo- choscopic treatment of cholelithiasis. Methods:The clinical data of 219 patients who had under- gone choledochoscopic treatment were analyzed retrospectively. Results: 21 cases were found with residual stones in the bile duct after the operations. Residual stone rate was to 9.58% . Bile duct stones of 8 patients could not be removed completely during operations. 13 patients were proved that stones still remain in their bile ducts by T-tube cholangiography and choledochoscope after opera- tions. There were 5 patients with acute obstructive suppurative cholangitis accompanying septic shock, 5 patients with stenosis in intrahepatic bile ducts, 4 patients with stones of in trahepatic bile duct and variation of bile duct, 2 patients with stones in sphincter of duodenal papilla,2 patients withstones and stenosis at the inferior segment of choledochus,3 patients were founded residual stones in bile duct obviously after the operations. Conclusions: B-type ultrasonic scanning and T-tube cholangiog- raphy are useful to reduce the rate of residual stones.

Objective To study the effects of different hypertonic saline (4.5%and 7.5%) in fluid resuscitation on hemodynamics in traumatic rabbits with hemorrhagic shock.Methods Thirty-two healthy rabbits ( male or female, 2.0-3.0 kg body weight) were divided into 4 groups randomly:SHAM group, SWT group ( shock without treatment) , 4.5%group (resuscitation with 4.5% hypertonic saline), and 7.5% group ( resuscitation with 7.5% hypertonic saline), 8 rabbits in each group.The rabbit model of uncontrolled hemorrhagic shock was established after anesthesia.The fluid used in the two methods of fluid resuscitation was infused into the rabbits at designed times.The hemodynamic data including the left intraventricular systolic pressure ( LVSP) and maximal change rate of left intraventricular pressure ( ±dp/dtmax) were determined at 0 min, 30 min, 60 min, and 90 min.Results (1) The rabbit models of uncontrolled hemorrhagic shock were generated successfully.At 30 min, data of SWT in the 4.5%and 7.5%groups had no significant difference through pairwise comparison (P>0.05).(2) The hemodynamic parameters changed similarly during the experiment.At 60 min, the values of the 7.5%group ( LVSP=115.00 ±8.37 mmHg, +dp/dtmax=4.29 ±0.50 mmHg/ms, -dp/dtmax=-3.25 ±0.25 mmHg/ms) were significantly higher than those in the 4.5%group ( ( LVSP=104.14 ±7.73 mmHg, +dp/dtmax=3.35 ±0.39 mmHg/ms, -dp/dtmax=-2.27 ±0.12 mmHg/ms) (P<0.05).At 90 min, the data of the 7.5%group were higher, but statistically not significantly different ( P>0.05 ) .Conclusions Fluid resuscitation can improve the hemodynamic function in traumatic rabbits with uncontrolled hemorrhagic shock.Comparing with the 4.5%hypertonic saline, 7.5% hypertonic saline can improve the hemodynamic function more apparently.Our results may provide an experimental support for the treatment of clinical patients with uncontrolled hemorrhagic shock.

CD38 is a multifunctional enzyme expressed in a variety of mammalian tissues, its catalytic activity was involved in a wide range of physiological processes. Based on the reported inhibitor of human CD38 NADase, 33 purine derivatives were designed and synthesized. The biological activity assay showed that compounds 20 and 38 exhibited almost the same extent of inhibitory activities on human CD38 NADase as the lead compound H2. The results also revealed that small substituents at C-6 of purine ring gave no obvious effect on inhibitory activity, but phenylpropionyl moiety at N-2 could affect the binding mode of the compound with CD38. This study provides a reliable basis for future rational design of inhibitors for CD38.

Objective To investigate the feasibility and effectiveness of fast track surgery (FTS) in neurosurgery. Methods One hundred fifteen patients who underwent neurosurgery surgery in Henan Province People's Hospital from June 2012 to March 2014 were enrolled in this study. All the patients were divided into FTS group (62 cases) and the tra?ditional operation group (53 cases). The clinical index, postoperative hospital stay and hospitalization cost were compared between the two groups. Results The clinical index were significantly lower in FTS group than in traditional operation group (P<0.05). Length of hospital stay (days) and hospitalization cost of FTS group were significantly shorter and lower in FTS group compared with traditonal operation group (8±1 vs. 11±2 days and RMB 4.58 ±0.75 vs. 5.78 ±0.64 ten thou?sand, respectively) (P<0.05). Conclusion FTS in neurosurgery operation is an all-new concept for surgery which can ef?fectively reduce postoperative complications, shorten length of hospital stay, decrease hospitalization cost and promote postoperative recovery.
