Objective To study the epidemiological features of patients for emergency transport so as to enhance the control level of pre hospital emergency treatment. Methods Investigations were made of 956 cases of patients for emergency transport in the authors hospital in 2000～2001 and their epidemiological features analyzed. Results Among the 956 cases, males outnumbered females, patients within the age group of 20 to 39 numbered 391, accounting for 40.9%, and patients within the age group of 50 to 69 numbered 400, accounting for 41.8%. Of all the cases, ordinary ones numbered 671(70.2%),critical ones numbered 241(25.2%), and cases that died numbered 44(4.6%). The first three diseases demanding emergency transport were successively craniocerebral wound(17.4%), cerebrovascular disease(16.0%), and cardiovascular disease(13.5%). The periods for emergency transport ranged mainly from 9:00 to 12:00 and from 15:00 to 18:00. The sources of emergency cases were successively township hospitals(53.8%), hospitals at the county level(26.0%), and hospitals at the city level(20.2%). Conclusion Control of pre hospital emergency treatment needs to be strengthened according to the epidemiological features of patients for emergency transport.

Objective To observe the clinical efficacy of acupuncture at the three tongue points plus tuina in treating hypersalivation in cerebral palsy.Method Sixty patients with hypersalivation due to cerebral palsy were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened predominantly by acupuncture at the three tongue points plus tuina, while the control group was by tuina alone. The clinical efficacies were compared between the two groups.Result The total effective rate was 96.7% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Acupuncture at the three tongue points plus tuina is an effective approach in treating hypersalivation in cerebral palsy.

Objective To explore the principles and methods of surgcal treatment for acute neoplastic colorectal obstruction.Methods The clinical data of 103 patients diagnosed as acute neoplastic colorectal obstruction were analyzed retrospectively.Results In this group,80 cases underwent emergency surgical treatment,(among) which,25 cases of carcinoma of right colon underwent primary resection and anastomosis;in 45 cases of carcinoma of left colon,primary resection and anastomosis was performed in 37 cases;and emergent(operations) were performed in 10 cases of rectal cancer.23 cases received non-emergency surgery.(Anastomotic) fistula occurred in 3 patients,pulmonary infection in 2 patients,pelvic cavity infection in 1(patient),1 patient died and the rest recovered well and were discharged.Conclusions The initial treatment for acute neoplastic colorectal obstruction should be non-surgcal treatment for 1~3d to make non-emergency surgical treatment more possible.If indications are properly selected,primary tumor resection and anastomosis is safe.For patients with severe contamination of abdominal cavity and bowel perforation, primary tumor(resection) should be performed if possible.

Objective To study the changes of the rat's hearing threshold by long-term treatment with Vitamin-C and the reason of the changes. Methods Forty-two Wistar rats were randomly divided into two groups: the treatment group was treated with water added Vit-C and the placebo group was treated with drinking water.(1)Concentrations of malondialolehyde(MDA)of the cochlea with fluorescence chromatometry.(2) Auditory sensibilities with auditory brainstem response testing.(3) The frequency of the mtDNA~(4834)bp deletion in the cochlea with polymerase chain reaction technique. Results Hearing threshold of both groups become worse with aging,and the treatment group showed the better auditory sensitivities,the less concentrations of MDA and the less frequency of mtDNA~(4834)bp deletion compare with the placebo group. Conclusions Long-term treatment with Vitamin-C could reduce the degree of hearing loss of the rats and the concentrations of MDA of the cochlea and the frequency of mtDNA~(4834)bp deletion in the cochlea.The oxygen radicals theory should be the etiology of presbyacusis.

Objective To investigate the geographic distribution of 5-HT2A T102C genotypes frequency in the PLA schizophrenia patients. Methods The 5-HT2A receptor gene T102C polymorphism was analyzed for genotyping by the method of polymerase chain reaction(PCR)in 177 male PLA schizophrenia patients. Results The distribution of 5-HT2A genotypic frequencies in 177 male PLA schizophrenia patients were 0.07~0.33(? 2=4.44,P=0.617 1) for A1A1, 0.50~0.72 for A1A2 (? 2=1.14, P=0.942 2), and 0.17~0.29 for A2A2 (? 2=0.93, P=0.985 7), respectively. There was no significant correlation between 5-HT2A frequencies and different populations. Conclusion The frequencies of 5-HT2A T102C genotypes in the PLA schizophrenia patients were uniform in different populations.

Objective To study the role of tumor necrosis factor alpha(TNF ?), interleukin(IL) 6 and IL 8 in the pathogenesis of condyloma acuminatum(CA). Methods Double antibody sandwich ELISA was used to study the levels of TNF ?,IL 6 and IL 8 in 21 cases of CA. Results The results showed that the levels of TNF ?,IL 6 and IL 8 of the plasma in the patients were significantly lower than those of normal controls. The levels of TNF ?,IL 6 and IL 8 produced by peripheral blood mononuclear cells in response to LPS mitogen in vitro significantly decreased in comparison with those of normal controls. The levels of IL 6 and IL 8 of the wart tissues excised from 17 patients were significantly lower than those of normal tissue. No TNF ? was detected in the tissues of both patient and normal groups. Conclusion These findings suggest that the monocyte macrophage function of CA patients might be decreased systemically and locally which may contribute to the disorder of lymphocyte function. Improvement of the monocyte macrocyte function might have some significant effect on the prevention and treatment of CA.

OBJECTIVE To analyze the caloric test findings of the unilateral primary horizontal and posterior semicircular canal benign paroxysmal positional vertigo(HSC-BPPV and PSC-BPPV).METHODS Caloric test were tested in 152 PSC-BPPV patients and 25 HSC-BPPV patients after Dix-Hallpike test and Roll test.RESULTS Of 152 PSC-BPPV patients 64 canal paresis(CP)were found in the abnormal side and 44 in the normal side;Of 25 HSC-BPPV patients 16 canal paresis were found in the abnormal side and 9 in the normal side.The incidence of CP in PSC-BPPV is 30.3% and the incidence of CP in HSC-BPPV is 52%.13 Patients with PSC-BPPV were found abnormal Directional Preponderance(DP)and 10 Patients with PSC-BPPV were found abnormal Directional Preponderance.CONCLUSION The incidence of CP in the abnormal side of HSC-BPPV and PSC-BPPV is more than that of the normal side.The incidence of CP in abnormal side of the HSC-BPPV is more than that of PSC-BPPV.The incidence of abnormal DP in HSC-BPPV is more than that of PSC-BPPV.

Objective To study the effectiveness of intravenous Lidocaine on subjective tinnitus in the elderly, and analyze its correlation with the effectiveness of subsequently oral Carbamazepine.Methods A prospective case-control study was conducted in 120 elderly patients with subjective tinnitus, who were divided into two groups.The control group (n=60) was treated with oral Carbamazepine 0.1 g Bid for one month, and the treatment group (n=60) was treated with 2％ lidocaine by intravenous injection.Patients in the treatment group were observed on responses in tinnitus during the period with Lidocaine injections.The treatment group was further divided into the improvement subgroup and the no-improvement subgroup, according to responses to intravenous lidocaine.All the patients in the treatment group received oral carbamazepine 0.1 g Bid for one month following the intravenous lidocaine injection phase.Results In the control group, 5 patients showed marked improvement, 20 patients showed partial improvement, 33 patients showed no improvement, and 2 patients showed symptom deterioration, with an effectiveness rate of 41.7％ (25/60).In the treatment group, 6 patients showed marked improvement, 26 patients showed partial improvement, 24 patients showed no improvement, and 4 patients showed symptom deterioration, with an effectiveness rate of 53.3％ (32/60).Of the 32 patients in the improvement subgroup, 6 cases showed marked improvement, 16 cases showed partial improvement, 8 cases showed no improvement, and 2 cases showed symptom deterioration after subsequent oral Carbamazepine treatment, and the effectiveness rate was 68.8％ (22/32).Of the 28 patients in the no-improvement subgroup, 1 case showed marked improvement, 9 cases showed partial improvement, 16 cases showed no improvement, and 2 cases showed symptom deterioration, and the effectiveness rate was 35.7％ (10/28).The effectiveness rate in the improvement subgroup was higher than in the no-improvement subgroup (68.8％ vs.35.7％, x2 =6.55, P＜0.05).The effectiveness of lidocaine followed by carbamazepine was better than that of carbamazepine alone (68.8％ vs.53.3％, x2 =6.13, P＜0.05).Conclusions Oral Carbamazepine treatment following intravenous Lidocaine injection in elderly patients with subjective tinnitus has better therapeutic outcomes than treatment with oral Carbamazepine alone, but is not as effective in patients with negative responses to Lidocaine as in patients with positive responses.

Objective:To evaluate the effects of perioperatively administrated enteral immunonutrition in gastrointestinal cancer patients on immune and inflammatory responses,nutrition states and postoperative morbidity.Methods:Sixty patients with gastrointestinal cancer were divided randomly into two groups.Two groups perioperatively(from preoperative day 5 to postoperative day 7) received an supplemented diet with arginine,RNA,and ?-3fatty acids(immunonutrition group;n=30) or an isoenergetic and isonitrogenous standard diet (standard-nutrition group;n=30).All variables of immune and inflammatory responses,nutrition states and postoperative morbidity were measured on preoperative day 5 and postoperative day 1,4 and 8.Results:On postoperative day 4 and 8,most immune variables and prealbumin in the immuno-group were significantly higher than those in the standard-group(P0.05),and inflammatory variables as CRP in the immunonutrition group were significantly lower than those in the standard group.In the immunonutrition group,there were significantly fewer patients who experienced postoperative complications and shorter days of hospital stay compared with standard group(P0.05).Conclusion:The perioperative administration of enteral immunonutrition in gastrointestinal cancer patients can significantly modulate the postoperative immunosuppressive and inflammatory responses at the early postoperative day,can significantly decrease the occurrence of infectious and overall postoperative complications as well as the length of hospital stay.

Hepatic fibrosis of rat was induced by CCl_4 and treated with tetrandrine(Tet). Results showed that Tet had obvious effect of anti-hepatic fibrosis which can be borne out by determining the activities of liver enzyme spectrum consisting of ALT,AKP,ChE,MAO and r-GT in serum. The meaurement can be observed dynamically, is noninvasive and more rapid,accurate and convenient than invasive hepatic biopsy. It provides valuable biochemical indexes for diagnosis,curative effect and prognostic judgement of hepatic fibrosis.
