Objective:To study on mechanisms of wrist-ankle acupuncture for prevention and treatment of peripheral neuritis complicated by diabetes.Methods:Ninety cases of peripheral neuritis complicated by diabetes were treated respectively by wrist-ankle acupuncture and body acupuncture,with western medicine routine treatment used as control group,30 cases in each group.The therapeutic effects and laboratory results were compared.Results:Therapeutic effects in wrist-ankle acupuncture group and body-acupuncture group were significantly superior to that in control group,with no significant difference between wrist-ankle acupuncture and body-acupuncture group.Conclusion:Wrist-ankle acupuncture can improve blood glueose and metabolism blood lipids,decrease blood viscosity and recover function of peripheral nerve cells and it has a definite effect on diabetic peripheral neuritis.

Objective To investigate and evaluate the feasibility and analgesic effect of ultrasound guided intercostobrachial nerve (ICBN) blockade in patients with persistent pain after radical mastectomy with ICBN preservation.Methods In a total of 53 following-up female cases,aged 18-55 years,ASA Ⅰ or Ⅱ,receiving radical mastectomy with ICBN preservation during January,2014 to February,2016,19 patients complained persistent pain in the lateral chest,axilla and/or upper arm more than 3 months after the surgery were enrolled.ICBN blockade was performed using 0.5% ropivacine 10 mL injected in the potential space between the superior of pectoralis minor muscle and the inferior of serratus anterior muscle in the second intercostal space guided by ultrasound.Visual analogue scale (VAS) was applied to assess the pain intensity at rest,on movement,and with 100 kPa pressure before blockage and 30 min thereafter,and then the pain intensity (SPI) was calculated.All nerve blockade-related adverse events including local anesthetic-related allergy,central nervous system and cardiovascular toxicity were recorded.Seven-day follow-ups were required in all patients to assess the pain intensity.Results All 19 cases completed ICBN blockade guided by ultrasound,of which 17 cases completed the seven-day follow-ups.The mean difference in SPI was-9.19 VAS points (95%CI-11.24--7.14,P<0.01).Compared with each mean VAS and SPI before block,all that after block at day 1-6 were significantly decreased (P<0.01 or P<0.05).There were 14(82.4%),13(76.5%),7(41.2%) and 3(17.6%)cases that SPI was decreased over 5 points after block at day 1-4.No nerve blockade-related adverse event was observed.Conclusion Ultrasound guided ICBN blockade can relieve persistent post-mastectomy pain safely and effectively.

Objective To study the influence of furosemide on the currents of the delayed rectification potassium channel and sodium channel of mice's spiral ganglion neurons.Methods Postnatal mice(P1～P6) spiral ganglion neurons were obtained by mechanical dissociation and enzymolysis.Delayed rectification potassium channels' currents and sodium channels' currents were recorded with whole-cell patch clamp techniques.Observed was the influence of furosemide on potassium channels and sodium channels.Results When furosemide was added around the spiral ganglion neurons,the delayed rectification potassium currents were inhibited to around +200～+300 pA,and sodium currents were inhibited to about 30% of peak current.Furosemide was washed away after working steadily for 1 minute,5 and 10 minutes.The delayed rectification potassium currents could recover to 98%,64%,and 25% of the peak currents before and sodium currents could recover to 96%,76% and 54% of the peak currents accordingly.Conclusion The currents of delayed rectification potassium channels and sodium channels could be inhibited by furosemide to different degrees.The longer furosemide was used,the greater damage could occur in the ion channels.

Objective To evaluate the clinical efficacy and safety of Holmium laser in the treat ment of calyceal stricture and atresia through antegrade percutaneous nephrostomy. Methods Ante grade percutaneous nephrostomy was performed in 68 patients with calyceal stricture and atresiathrough a rigid 8/9.8 F ureteroscope. The stricture and atresia was incised in a linear fashion by theHolmium laser with a 550 mm fiber. After completion of the incision,a double J ureteral stent wasplaced for 6-8 weeks and nephrostomy tube was kept for 7 days thereafter. Patients were then fol lowed up with IVU and/or ultrasound at 3-6 month intervals. Results The mean operative timewas 90 min,ranged from 80 to 120 min. The mean postoperative hospital stay was 8 d(7-9d). Hy dronephrosis was significantly improved in 38 cases in an average follow up of 9 months (4-26 months). Repeated laser incision was performed to 4 treatment failures and all turned out to be suc cessful. Conclusions The Holmium laser treatment through antegrade percutaneous nephrostomyfor calyceal stricture and atresia has characteristics of minimal invasion,short hospital stay,good effi cacy in short term and repeated cases. This procedure to be used as the first choice for patients withgood renal function and mild hydronephrosis,especially accompanied with renal calculus.

OBJECTIVE: To explore a method for locating the area of lacrimal sac in dacryocystorhinostomy under endoscopy. METHOD: Sixty-eight patients were performed dacryocystorhinostomy under endoscopy. Take light spot of ocular optic fiber as the lacrimal sac projection to the lateral wall of the nasal cavity position. RESULT: With the guiding of ocular optic fiber, lacrimal sac can be located accurately. The operating time of dacryocystorhinostomy under endoscopy was shortened significantly, and the operation procedure was simplified. All patients were followed up for 2 years, only 2 recurrent cases were found. The success rate reach to 97.06% (66/68). CONCLUSION Ocular optical fiber used in locating the lacrimal sac in dacryocystorhinostomy under endoscopy is simple and feasible, and can be widely used.

OBJECTIVE: To get a method of dacryocyst allocation for dacryocystorhinostomy per nasal endoscope. METHOD: The dacryocyst of 7 chronic dacryocystitis cases(8 eyes) were located through nasal cavity guided by endo-ophthalmic optical fiber. RESULT: All the 7 patients got successful operations, the bleeding was 10-20 ml during the operation , postoperative recovery was good, no infection occurred. Five patients received operations twice, all of them were detained anaesthetic tubes for 3 to 6 months, dacryocyst rinsing were conducted once per month after extubation. No obstructions and complications occurred after one year follow up. CONCLUSION Endo ophthalmic optical fiber can be used to locate dacryocyst in dacryocystorhinostomy per nasal endoscope.

Objective:To analyze the relationship of hepatic transit time and portal vein pressure in the patients with portal hypertension and esophagogastric varices, and to clarify its clinical significance.Methods:A total of50hospitalized patients underwent esophagogastric venous embolization due to portal hypertension and esophagogastric varices were selected as observation group, and 50patients without history of liver disease and clinical manifestations of liver disease (hospitalized or out-patient) were selected as control group, All patients underwent liver contrast enhanced ultrasound.The free portal pressure (FPP) was measured by ultrasound guided portal vein puncture for operating pathways in the patients in observation group.The hepatic artery-hepatic vein transit time (HA-HVTT) , the hepatic portal vein-hepatic vein transit time (PV-HVTT) , the liver parenchymahepatic vein transit time (PA-HVTT) of the patients were compared between two groups.The correlations between HA-HVTT, PV-HVTT, PA-HVTT and FPP of the patients in observation group were analyzed.Results:The HA-HVTT, PV-HVTT and PA-HVTT of the patients in observation group were significantly shorter than those in control group (t=5.078, P＜0.01;t=12.163, P＜0.01;t=2.649, P＜0.01) .The HA-HVTT, PV-HVTT and PA-HVTT had negative correlations with FPP in observation group (r=-0.799, P＜0.01;r=-0.554, P＜0.01;r=-0.735, P＜0.01) .The linear relationship between HA-HVTT and FPP was Y=-0.410X+7.254;the linear relationship between PV-HVTT and FPP was Y=-0.355X+4.983;the linear relationship between PA-HVTT and FPP was Y=-0.566X+4.997.Conclusion:Liver transit time can be used as an effective index to judge the portal vein pressure, and it can provide the theroretical basis for the diagnosis and treatment of portal hypertension in the patients.
