Objective To investigate the clinical efficacy of cobamamide combined with Longxuejie in the treatment of herpes zoster in the elderly .Methods 104 elderly patients with herpes zoster were randomly divided into the treatment group and the control group .Both the two groups were given orally famciclovir 250mg,3 times a day for 14 days,intramuscularly injected gland glycosides cobalamin 500mg,1 day,14 days a course of treatment ,the treat-ment group was given Longxuejie enteric-coated tablets 4,3 times a day orally for 14 days.The blisters disappeared , pain relief,and recovery time of completely crusted ,treatment efficacy and neuralgia were compared between the two groups.Results In the treatment group,34 cases were cured,effective in 13 cases,total effective rate was 90.4%, which was significantly higher than 73.1% in the control group,the difference was statistically significant (χ2 =5.216,P<0.05).The blisters disappeared,pain relief,and recovery time of completely crusted in the treatment group were significantly shorter than those in the control group (t =3.216,5.432,4.643,3.654,all P <0.05).No postherpetic neuralgia was observed in the treatment group ,the incidence rate of postherpetic neuralgia of the control group was 13.5%,the difference was statistically significant (χ2 =4.875,P<0.05).Conclusion The Longxuejie combined with cobamamide in the treatment of herpes zoster in elderly patients has reliable effect ,fast improvement of clinical symptoms,a low incidence of postherpetic neuralgia ,it is worthy of clinical application .

Objective To explore the expressions and significances of sICAM-1 and sCD44v6 in peritoneal lavage fluid after laparoscopically assisted radical gastrectomy,in order to evaluate the risk of laparoscopically assisted radical gastrectomy for the peritoneal plant transfer.Methods Ninety-two patients with gastric cancer were randomly divided into the control group and the experimental group.The control group was treated with open laparotomy and the experimental group was treated with laparoscopic surgery.The concentrations of both sICAM-1 and sCD44v6 were detected by enzyme linked immunosorbent assay.The positive rates of tumor cells in the two groups were compared.Results The expressions of sICAM-1,sCD44v6 in the two groups before operation had no significant difference (t =0.198,P =0.543 ; t =0.897,P =0.429).After operation,sICAM-1 and sCD44v6 levels increased significantly,but there was no significant difference between the two groups (t =0.766,P =0.312 ; t =1.092,P =0.129).The positive rates of tumor cells in the two groups before and after operation have no significant differences (x2 =0.789,P =0.287 ; x2 =0.912,P =0.198).Conclusion Laparoscopically assisted radical gastrectomy does not increase the expression of sICAM-1 and sCD44v6 in peritoneal lavage fluid and the risk of peritoneal metastasis.It is worthy of clinical poptdarization and application.

The present paper is an analysis of the pattern reversal visual evoked potentials (P-VEP) of macular disease (40 cases, 57 eyes), in contrast to normal persons (40 cases, 80 eyes) of similar age. The group consists of 9 different kinds of disease-central serous chorioretinopathy macular hemorrhage, macular dege-neration, etc. The authors analyzed the latency and amplitude of P-VEP in different macular disease with different course and central vision. The results showed that the latency of P-VEP in the group was relatively prolonged. In contrast to normal person P 100 was prolonged by 9.0, 26, 40 ms at 1?2′, 30′, 16′ visual angles respectively. The amplitude was obviously lowered, especially at the visual angle of 16′ and P-VEP extinguished in all the eases with visual acuity less than 0.1.The latency and the amp-litude were not related to the type and the course of the maeular disease, but were closely related to the central vision.

OBJECTIVE:To enhancement lawconsciousness and ability of self-protect of pharmacist.METHODS:Analysed the problem which occured in their work from the point of view of law and bring forward some advice.RESULTS &CONCLUSION:Pharmacist should do their work strictly according to the code for avoidance law risk.

Objective To exclude AC disturbances resulted from ambient condition in the process of magnetic resonance imaging. Methods study ten low field MRI systems and analysis the images with AC disturbance, then compare measured data of ambience, one of which is disturbed seriously, the other is no disturbance. By removing the power lines and adding isolating transformers and eliminating metal pipes and so on, the useful method is summarized. Results Magnetic field strength giving rise to AC disturbances ranges from 2 mGs to 4 mGs (the standard is less 1 mGs). It will produce circle artifacts. The artifacts pass away when magnetic field strength was decreased to 1 mGs. Conclusion installing MRI sets, disturbing resources must be 10 m far away from them.

OBJECTIVE: To enhance the quality of pharmaceutical care of licensed pharmacists in medical services, and to ensure safe, effective, economical, and rational use of drugs. METHODS: The status quo and the problems existing in the legal guarantee of licensed pharmacists in medical service were analyzed, and the necessity of reinforcing legal guarantee for licensed pharmacists in medical service and the feasible measures were discussed. RESULTS & CONCLUSIONS: It is urgent to set and enforce "Licensed Pharmacist Law" to safeguard the legal rights of licensed pharmacists in medical service in the mo-de of law, facilitate the implementation of licensed pharmacist system in medical service, consummate management on licensed pharmacists, reinforce licensed pharmacists' consciousness of legal guarantee, and enhance the quality of pharmaceutical care.

Objective To study the effect of acid burn on rat corneal endothelial damage and its repair.Methods The model of mild,moderate and severe acid burn in cornea was established in 90 Long-Evans rats(n=30 for each degree of acid burn) with 4 rats served as normal controls.Corneal edema,opacity and the healing of epithelium were observed with a slit lamp microscope.The corneal endothelium from half rats of each degree acid burn was stained with trypan blue and alizarin red,and that from the other half with hematoxylin and eosin(HE) immediately,30 min,1,3,7,14,21,28 d after cautery.The endothelial damage and its repair were observed and the number of the leucocytes in cornea was calculated under light microscope.Results No damage was seen in the corneal endothelial cells of mild,moderate acid burn,only a few leucocytes could be seen in the cornea,and the healing of epithelium,the regression of edema were within 7 d.The endothelial cells necrosed and shedded in the wound area by severe acid burn.The endothelial cells in the margin were deformed,elongated and slided to the damaged area during repair,and a great number of leucocytes infiltrated,the healing of corneal epithelium was delayed,the regression of edema was up to 28 d.Conclusion The corneal endothelial cells were damaged in severe acid burn.The secondary inflammatory reaction took part in the damage of corneal endothelial cells after severe acid burn.The damage of endothelial cells delayed the healing of corneal ulcer and edema.

Artificial hip replacement is an effective therapy to eliminate hip pain,correct deformity and restore function.With population aging and improving of people life quality,artificial hip replacement has been widely conducted.Over the past 40 years,artificial hip replacement technique has rapidly developed,and minimally invasive technology presents development direction of future artificial hip replacement.Skilled operation experience and instrument application are two key factors to ensure surgery success.The minimally invasive technology arouses more attention from clinical doctors and patients due to minimal invasion,little blood loss and fast recovery.However,not all patients can undergo minimally invasive hip replacement.This paper summarized related studies on minimally invasive hip replacement in domestic,and discussed the indications,surgical approach,complications and prevention.
