Objective To observe the neural protective subsidiary effect of Wenyang Yiqi method on patients with severe traumatic brain injury under mild hypothermia therapy.Methods A prospective study was conducted in which 53 patients with severe traumatic brain injury treated by mild hypothermia were randomly divided into control group (26 cases) and observation group (27 cases). All the patients in the two groups received conventional western treatment combined with mild hypothermia therapy. In the observation group, additionally was given the representative drug of Wenyang Yiqi method, Shenfu injection 100 mL mixed into 5% glucose 500 mL intravenous drip once a day. At the end of mild hypothermia, the Shenfu injection was stopped. After treatment, the changes of intracranial pressure (ICP) on 1 (the day the treatment began), 2, 3, 4, 5, 6 and 7 days and the indexes levels, including S-100B, lactate dehydrogenase (LDH) and creatinkinase (CK) in the cranial spinal fluid (CSF) before treatment and 2, 4, 6 days after treament (CSF) were observed. The Glasgow coma score (GCS) before treament and 3, 5, 7, 14, 28 days after treament, and Glasgow outcome scale (GOS) on 28 days and 3 months after treatment were recorded, and the incidences of complications were calculated at the end of therapy.Results After treatment with the prolongation of therapeutic time, the levels of ICP were gradually increased in two groups and reached the peak values on the 4th day, then beganto fall, and on the 5th day it was significantly lower in observation group than that in control group [ICP (mmHg, 1 mmHg = 0.133 kPa): 16.11±1.23 vs. 18.73±1.42], persisting the same situation to the 7th day (14.17±0.80 vs. 16.94±1.00,P < 0.05). The levels of S-100 B in the two groups were progressively decreased after the treatment, on the 2nd day it was significantly lower in observation group than that in control group (μg/L: 1.21±0.43 vs. 1.86±0.57, P < 0.05), also persisting to the 6th day (0.40±0.09 vs. 0.94±0.15,P < 0.05); the levels of LDH and CK reached the peak values on the 2nd day, then began to fall, they were significantly lower in the observation group than those in the control group on the 4th day [LDH (U/L): 63.43±12.21 vs. 80.11±14.34, CK (U/L): 52.41±14.14 vs. 88.37±12.21, bothP < 0.05], and on the 6th day still there were statistically significant differences between the two groups. The GCS before treatment showed no statistically significant difference between the two groups (P > 0.05); after treatment, the GCS score of the two groups was progressively improved, and on the 14th day the score in the observation group began significantly higher than that in the control group (11.74±1.24 vs. 9.41±2.11,P < 0.05), persisting the same situation to the 28th day (12.68±2.51 vs. 10.67±1.99,P < 0.05). On the 28th day after treatment, the GOS showed no statistically significant difference between the two groups (2.35±0.16 vs. 2.43±0.22,P > 0.05), but the score in the observation group was significantly higher than that in the control group after treatment for 3 months (4.11±0.38 vs. 3.72±0.41, P < 0.05). The incidences of complications in the observation group were significantly lower than those in the control group [respiratory failure: 25.9% (7/27) vs. 50.0% (13/26), shock: 18.5% (5/27) vs. 53.8% (14/26), acute pulmonary edema: 14.8% (4/27) vs. 30.8% (8/26), stress ulcer: 22.2% (6/27) vs. 57.7% (15/26), hypoproteinemia: 40.7% (11/27) vs. 73.1% (19/26), allP < 0.05].Conclusion Wenyang Yiqi method has the subsidiary neural protective effect on patients with severe traumatic brain injury treated by mild hypothermia, and can improve their outcome.

Objective To investigate the effect of endoscope assisted microincision cholelithotomy(EMC) in the treatment of gallstone. Methods The clinical data of 86 patients with gallbladder stone treated by EMC were analyzed retrospectively.Of them, 63 cases were follwed-up and studied. Results All eighty-six patients were successfully operated on and discharged, no operative complications occurred. Among 63 patient being followed up for 1~3 years,the recurrence rate of gallbladder stones was 3.2%(2/63). No recurrence was noted in 46 patients with single gallstone. In the other seventeen patients with multiple stones, gallstone recurrence was found in 2 patients, the recurrence rate was 11.8%(2/17). Conclusions If selection of the operation idications are strict, endoscope assisted microincision cholelithotomy for treatment of gallstone is simple, safe, effective and less trauma, and can preserves the function of gallbladder, but it can not replace the cholecystectomy.

Objective To investite the effect of endotoxin pretreatment on lung injury induced by hepatic ischemia reperfusion in rabbits and its mechanism. Method Forty-eight New Zealand white rabbits were randomly divided into4 groups with 12 rabbits each group:routine control group,pretreatment control group,ischemia reperfusion group (IR group), and preperfusion group( LPS + IR group). Rabbits of routine control group received operative dissector only, and those of pretreatment control group received pretratment of daily intraabdominal injection of lipopo|ysaccharide(O.5,0.5,and 1.0 mg/kg,respectively)in the 3 days before operative dissector.Livers of IR group were rendered and ischeraic for 30 minutes, and repeffused for up to 4 hours. Rabbits of LPS +IR group received the preueaunent before heretic ischemia repeffusion. Four hours after reperfusion, serum endotoxin,tumor necrosis factor-α(TNF-α), wet/dry ratio and broncho-alveolar lavage fluid protein content of lung,malondialdehyde(MDA) and mpenrxide dismutase(SOD) in lung homogenate, lung injury ratio, and activity of Nuclear factor-kB(NF-kB) in alveolar macrophage wene examined. Differences within the groups were analyzed using One way ANOVA. Results Between the two control groups,there were no significant differences in all indexes(P>0.05). The TNF-α[ (48.31±5.31)pg/ml vs.(56.47±5.09)pg/ml, P<0.01],wet/dry ratio [(4.98±0.33)vs. (5.22±0.31), P = 0.03],broncho-alveolar hvage fluid protein content[(0.68±0.11)g/L vs. (0.76±0.10)g/L, P =0.04],MDA[(0.86±0.06)nmol/mg vs. (0.93±0.07)nmol/mg, P =0.02],lung injury ra-tio[(13.4±4.3)% vs. (17.4±4.1)%, P = 0.03],and the activity of NF-gB[(5.82±1.12)OD/mm2 vs.(7.40±1.26)OD/mm2, P<0.01] in alveolar macrophage of the LPS+ IB group were all significantly lower than those of IB group, while the SOD[ (90.30±7.38 )U/rag vs. (84.44±7.90 )U/rag, P = 0.04]of LPS + IR group was significantly higher than that of IR group. Conclusions Endotoxin pretrealment may ameliorate the lung injury induced by hepatic isehernia reperfusion. The mechanism may be that endotoxin pretreatment deoreases production of serum TNF-α and the activity of NF-kB in alveolar maerophage.

Objective To evaluate the effect of via-anal preoperative depression with assistance of colonoscopy and primary stage laparoscopic cancer resection and anastomosis for the treatment of malignant obstruction of left-sided colon. Methods Eleven cases of malignant left-sided colonic obstruction were treated from December 2004 to August 2007 by this modality.With the help of colonoseopy and the guiding of radiography,ileus tube was inserted into the proximal bowel of the obstructive site via anus.We used the tubes to decompress the dilated bowel.Patient's symptom,bowel sounds,abdominal girth,intra-abdominal pressure,plain abdominal radiograph were observed.After the relief of bowel obstruction,elective laparoseopic colorectal resection and anastomosis was accomplished in one stage with routine preoperative preparation.Results After 5~14 days of depression by ileus tube,the relief of bowel obstruction was achieved in all these patients hence emergency operation wag avoided.Elective first-staged laparoseopic resection and anastomosis was performed in all 11 cases.The complications such as anastomotic leakage and incisional/abdominal cavity infection were not observed.After an average 15.2-month fouow up,local recurrence rate,incisional or port implantation rate,and tunlor-free survival rate were 9%,0 and 91% respectively. Conclusions First-staged laparoscopic resection and anastomosis assisted by preoperative colonoscopic depression in malignant left-sided colonic obstruction is a safe and effective procedure.
