Objective To achieve the software automatic updates and maintenance in the local area network which is developed based on the C/S structure. Methods Based on the existing software and hardware development platform,we use PowerBuilder to exploit and compile a program which can determine whether the software need to update automatically or not under the premise of unchanging the existing LAN software system. Results When the user terminal in the local area network runs this program,they can update it automatically whenever they need. Conclusion This method will greatly reduce the later maintenance software,upgrade works and also improve the work efficiency and accuracy.

A 41 years female patient was hospitalized with hoarseness for three months, without cough, expectoration and dyspnea. The symptom had no relief by application of antibiotics. Electronic laryngoscope showed that there were the grey neoplasms under subglottic anteriou commissure with broad base and slightly rough surface, and bilateral vocal cords were normal; throat CT showed subglottic irregular high density and calcification. The subglottal tumor resection was performed under the general anesthesia and laryngoscope CO2 laser assisted. In the operation, we found that the tumor was hard with surface of thin mucosa tissue, and there was white bone tissue under it. The removing tumor was about 0. 8 cm X 0. 6 cm X 0. 3 cm and was diagnosed as subglottic osteoma by pathologic examine. There was no recurrence in three months follow-up.

Objective To analyze the clinical efficacy of compound 18 norgestrel combined with estrogen in treatment of dysfunctional uterine bleeding. Methods 78 cases of patients with dysfunctional uterine bleeding in Beijing Ji Shui Tan Hospital and Dongguan city people's hospital of guangdong Province were divided into control group (n=39)and observation group (n=39)by using randomized single-blind allocation. The control group was only given estrogen,the observation group was used compound 18 norgestrel combined with estrogen. The clinical efficacy of the two groups was compared. Results 31 cases were cured and 7 cases were valid of the study group,the total effective rate was 97.4%,significantly higher than the control group's total efficiency of 71.8%,the difference was statistically significant (P<0.05). Each index of observation group and the control group were improved after treatment,the difference was statistically significant (P<0.05 );After treatment,the menstrual cycle in observation group was (29.7 ±7.1)d,the menstrual period was (5.6 ±0.5)d,hemoglobin content was (135.5 ±21.7)g/L,endometrial thickness was (0.63 ±0.15)mm, significant changes than the control group,the difference was statistically significant (P<0.05 ). Conclusion Compound 18 levonorgestrel combined with estrogen has a better effect in patients with dysfunctional uterine bleeding and it can significantly improve patients'hemoglobin,the menstrual cycle and the uterus film thickness and other indicators which is worth promoting in clinical.

Objective To investigate the extent and the relevant factors for local lymph node metastasis of gallbladder carcinoma. Methods Clinicopathologic features of 34 patients with gallbladder carcinoma who underwent radical resection were analyzed retrospectively. Results The overall lymph node metastasis rate was 68%(23/34), with 0(0/3) in T 1 stage, 43%(3/7) in T 2, 85%(11/13) in T 3, and 82%(9/11) in T 4. The metastasis rate was 29%(10/34) in gallbladder lymph nodes, 44%(15/34) in pericholedochal, 18%(6/34) in hepatic hilum, 24%(8/34) alongside proper hepatic artery, 21%(7/34) in periportal vein, 38%(13/34) in retropancreaticoduodenal, and 4/6 in paraaortic region. Conclusions Lymph node metastasis was determined by the depth of invasion of the primary tumor. The extent of surgical dissection was made according to the exploration and result of intraoperative biopsy.

Objective To investigate the protective effects of transection of the cervical sympathetic trunk (TCST) on the gastric mucosal lesions in rats fastened to a board and immersed vertically in water, up to the level of xiphoid with the animals' heads up water for 6 hours. Methods Thirty male SD rats weighing 200-250 g were randomly divided into 3 groups ( n = 10 each): group A sham operation; group B sham operation + water immersion and group C TCST + water immersion. The animals were anesthetized with intraperitoneal 2.5% pentobarbital 40 mg?kg-1. Cervical sympathetic trunk was exposed at right common carotid artery bifurcation and cut. The gastric mucosal blood flow (GMBF) was measured with Doppler blood flow monitor after 6 h water immersion. Blood samples were taken from abdominal aorta for determination of plasma concentration of ET-1 and serum concentration of NO. Gastric mucosal ulcer index was determined according to Guth criteria.Results There was gastric mucosa bleeding and erosion in group B and C and the degree of injury was severer in group B than in group C. Plasma concentration of ET-1 and serum concentration of NO were significantly higher in group B than in group C and A.Conclusion TCST has protective effect on gastric mucosal blood flow in rats under stress by reducing blood ET and NO concentrations.

Acute kidney injury (AKI), a common clinical dis-ease, is one complex pathophysiological process. In this review paper, the relationship and the molecular mechanisms of ische-mia-reperfusion, major surgery, rhabdomyolysis, pus sepsis and drug-induced renal toxicity associated with AKI were comprehen-sively reviewed. In addition, the prevention and treatment of AKI by Chinese medicine and the effective components were also reviewed. Therefore, our review aims to provide valuable infor-mation for treatment of AKI, and also for exploration of innova-tive new drugs.

Objective To evaluate the diagnostic values of MRA,TCD and ultrasonography in carotid territory transient ischemic attacks (TIAs). Methods 42 patients with carotid territory TIAs were examined by MRA, TCD and ultrasonography. Results MRA showed abnormalities of carotid arteries in 12 cases (28.6%) and abnormalities of intracranial arteries in 32 cases (76.2%). 8 cases presented abnormalities both in carotid arteries and intracranial arteries. Abnormalities of intracranial arteries were detected by TCD in 30 cases (71.4%) and abnormalities of carotid arteries were detected by ultrasonography in 16 cases (38.1%).Conclusion MRA, TCD and ultrasonography are useful in the evaluation of etiological factors of carotid territory TIAs.

Objective Low-dose naloxone has been shown to reduce side-effects of morphine while morphine analgesia is not antagonized and may even be enhanced. The purpose of this study was to evaluate the effects of low-dose naloxone infusion (50 ng? kg-1? h-1 ) on morphine analgesia and plasma levels of opioid peptides in patients after abdominal hysterectomy.Methods Forty-two ASA Ⅰ- Ⅱ patients aged 36-50 yrs, weighing 55-67 kg undergoing abdominal hysterectomy under combined spinal-epidural anesthesia were enrolled in this study. Spinal puncture was performed at L2-3 interspace. The patients received intrathecal 0.75% ropivacaine 2.0-2.6 ml. 2% lidocaine was used for epidural injection. The block height was maintained at T8-6 . For postoperative analgesia the patients were randomized to receive either intravenous morphine infusion at 10 ?g?kg-1 ?h-1 (group M, n = 21) or IV morphine infusion (10 ?g?kg-1?h-1)+ naloxone infusion at 50 ng?kg-1?h-1 (group MN, n = 21). Pain was assessed using VAS (0-10) with 0 representing no pain and 10 representing the worst possible pain. Blood samples were taken from peripheral vein before anesthesia (T0), at the end of surgery (T1) and at 6, 24, 48 h (T2,3,4) after operation for determination of plasma levels of ?-endorphin (?-EP), dynorphin A1-13 (Dyn) and leu-enkepholin (L-EK) .Results The patients were comparable with respect to, age, weight, occupation and duration of operation between the two groups. Two patients (1 patient in each group) were excluded from the study because of their refusal to have repeated blood samples taken. The analgesia was significantly better in group MN than that in group M in terms of VAS scores. Plasma level of ?-EP was significantly lower at 6 h after operation (T2 ) but significantly higher at 24 h postop. (T3 ) in group MN compared with that in group M ( P
