Objective To observe the effect of therapies of activating blood and removing stasis, activating yang and dissipating phlegm, and warming and dredging meridians with aromatic herbs on relieving acute myocardial ischemia (AMI). Methods Rats were randomized into normal group,model group, Xuefu Zhuyu Decoction (XZD) groups (treated with XZD 20.5 and 6.8 gkg-1d-1 ), Gualou Xiebai Banxia Decoction (GXBD) groups (treated with GXBD 18.0 and 6.0gkg-1d-1 ), and Guanxin Suhexiang Capsules (GSC) groups (treated with GSC 0.19 and 0.06 gkg-1d-1 ). The AMI rat models were established by intravenous injection of pituitrin (Pit, 1.5U/kg) through the caudal vein. The effect of the three Chinese medical therapies on AMI rat electrocardiogram (ECG) and plasma endothelin (ET) level was evaluated. Results Compared with the model group, statistical significance was presented in the rise of ST segment of medication groups (P

Objective To explore more safe and effective method for the treatment of common bile duct stones combined with cavernous transformation of the portal vein (CTPV).Methods We report 2 cases of post-treated patients in this series.In order to avoid severe bleeding caused by dissection of bile duct,we applied different methods to remove common bile duct stones compared with traditional operation.We removed common bile duct stones in one patient through cystic duct approach during operation.Two years later,we performed endoscopic duodenal incision (endoscopic sphincterotomy,EST) for him because of lower common bile duct stenosis with sand like stone.Another patient,on the other hand,we conducted the duodenal papilla incision during operation and removed common bile duct stones with choledochoscope through the bottom of common bile duct.Result Of the two patients,all of the three kinds of operation had good curative effects.Conclusions For the patients with common bile duct stones combined with CTPV,we should select appropriate treatments to avoid dissection of bile duct in front of the dilated and tortuous collateral veins during the operation,which is the key to guarantee the safety and success of the operation.EST is the preferred method of the treatment.Open operation with choledochoscopy via cystic duct approach or duodenal papilla incision through distal common bile duct to perform stone extraction also appears to be effective and safe.

Liver transplantation is one of the main treatments for acute and chronic liver failure currently.In recent years,with the lack of donor liver transplantation and the in creasing number of patients,the major donator of liver transplant is brain dead patients.In brain-dead state,organ functions de cline gradually.Changes in hemodynamics and immunity could lead to inflammation and alter hormone release.Organ survival and patients'prognosis can be unpredictable.The study of the above phenomenal mechanisms is still at an early stage.This article summarized the current liver transplant treatments by explai ning the pathophysiology of donor organ damage and reviewing the prognosis.The aim of this article was to provide a perspective for future study on this topic.

Objective To investigate the feasibility and outcome of resection and reconstruction of hepatic artery in hilar cholangiocacinoma (HCC).Methods The data of 29 patients with HCC with hepatic artery reconstruction carried out from March 2009 to August 2013 in our center were retrospectively analyzed.23 right hepatic arteries and 6 common hepatic arteries were involved.In-situ anastomosis was carried out in 20 patients and a double anastomosis using gastrodoudenal artery grafts was carried out in 9 patients.Results There were no arterial thrombosis or other related complications on prolonged follow-up.Conclusion Hepatic artery resection and reconstruction should be carried out if the artery was invaded by a hilar cholangiocarcinoma to produce a high resection rate and a better outcome.

OBJECTIVE To investigate the postoperative morbility of deep fungal infections and the source and composition of the pathogenic fungi.METHODS Clinical data of 816 patients with post-operative deep fungal infections from Jul 2006 to Jun 2008 were reviewed and analyzed retrospectively.RESULTS The detectable rate of post-operative deep fungal infections was 24.82%,among which Candida albicans was the most common(65.69%),followed by C.tropicalis(10.57%);the rate of broad-spectrum antibiotic application in peri-operation was 96.45%;the infection site in the descending order was cardio-thorax,gastrointestinal tract,urinary tract,female reproductive system,blood and skeleton.CONCLUSIONS Operative trauma is an important factor that causes deep fungal infections in hospital,and is closely related to broad-spectrum antibiotic application.Positive prevention,timely diagnosis and effective treatment should be highly emphasized when dealing with post-operative deep fungal infections.

Objective:To investigate the expression of amphiregulin in human endometrium during the menstrual cycle.Methods: Endometrial tissues were collected from the patients undergoing hysterectomy or endometrial biopsy.Real-time RT-PCR,in situ hybridization and immunohistochemistry were used to detect the expression characteristics of amphiregulin in human endometrium in proliferative and secretory phases.Results: Real-time RT-PCR showed the expression of amphiregulin mRNA in secretory phase was 32 times that in proliferative phase.The results from in situ hybridization and immunohistochemistry showed that amphiregulin was located in the cytoplasm and mainly expressed in the gland of endometrium.The expressions of amphiregulin mRNA in proliferative and secretory phases were 0.54?0.22 and 2.96?0.47(P

Objective To analyze the perioperative complications and prognosis of surgical treatment of pancreatic ductal stones.Methods 60 patients diagnosed to have pancreatic ductal stones and were admitted into our hospital from January 2009 and December 2014 were enrolled into this retrospective study.There were 47 males and 13 females.The average age was (44.1 ± 12.0).Results All patients underwent surgical operation and there was no perioperative death.Perioperative complications occurred in 7 patients (11.7％), including pancreatic fistula in 4 patients, delayed gastric emptying in 1 patient, abdominal infection in 1 patient, anastomotic bleeding in 1 patient.Eight patients developed elevated amylase levels.The fasting time was 3.4 ± 1.2 days and the hospital stay was 10.0 ±4.0 days.The follow-up rate was 88.3％ (53/60), at a mean follow-up of 27 months.In 51 patients who presented with abdominal pain, 43 patients (84.3％) had complete pain relief and 7 patients (13.7％) had partial pain relief.In 14 patients with preoperative diabetes mellitus, 1 patient had improvement and 2 patients recovered from diabetes.Two additional patients were diagnosed to have diabetes two years after the operation.Of the 2 patients who were shown to have pancreatic cancer on histopathological study, 1 patient was lost to follow-up while another patient died at 27 months after the operation.The patients diagnosed to have epithelial dysplasia were followed-up and none developed pancreatic cancer.Conclusions The relationship between chronic pancreatitis and pancreatic ductal stones was very close.Chronic pancreatitis also caused exocrine and endocrine dysfunction.Surgical operation plays an important role in symptomatic relief and in delaying pancreatic dysfunction.

BACKGROUND: The injury of blood-brain barrier following cerebral ischemia reperfusion is a considerate pathological basis for injury caused by cerebral ischemia and reperfusion.OBJECTIVE: To investigate the effects of four most basic Chinese medicinal herbs, or safflower, peach seed, ligusticum and red peony with actions of activating blood and resolving the stasis on the contents of nitric oxide, immunoglobulins, C-reactive protein (CRP) and complements (immunological indices) of serum and cerebral homogenate, as well as the morphological and structural changes of cerebral tissue cells in rats with ischemia and reperfusion to vertify relationship between time effectiveness and quantitative effectiveness.DESIGN: A randomized controlled study, and evaluation by single blind.MATERIALS: The experiment was completed in the Laboratory of Traumatology Institute of Guangzhou Red Cross Hospital from January 2001 to De cember 2002.

No. 2 medicated group: The BASR was by garage given in a dose of 2.5 g/kg 30 minutes before operation. No. 3 medicated group: The BASR was by garage given in a dose of 2 g/kg for consecutive 7 days be fore operation. No. 4 medicated group: The BASR was by gavage given in a dose of 2.5 g/kg for consecutive 7 days before operation.Control group:the same volume of saline was by gavage given for consecutive 7 days before operation. ① Scoring of dysneuria (5-score system: 0-1 score meant mild dysneuria, 2-4 scores meant severe dysneuria) for all rats were performed after consciousness following 2 hours ischemia and 24 hours reperfusion.② After 24 hours reperfusion,10 rats in each group were at random selected for assay of levels of CRP, complement 3 (C3) and complement 4 (C4) (rate nephelometry), and concentration of nitric oxide (nitrate reductase method)in both cerebral homogenate and serum.③ After 24hours reperfusion, 10 rats in each group were at random selected, and after anesthesia was completed, the brain was quickly collected through decapitation, put into a 110 ℃ drying oven till its constant weight, then the water content in brain was calculated.④ The cerebral cytomorphology in every group was observed under light microscope. ⑤ After reperfusion, 3 rats in each group were randomly selected for preparation of coronal section of cerebral tissue,the cerebral ultrastructure in each group was observed under transmission electronic microscope.MAIN OUTCOME MEASURES: ① The results of dysneuria scoring in each group. ② The levels of CRP, C3 and C4, and concentration of nitric oxide in both cerebral homogenate and serum.③ The water content in brain. ④ The cerebral cytomorphology and the cerebral ultrastructure. RESULTS: All 138 rats entered into the result analysis. ① Comparison of the extents of dysneuria of rats in each group: The ratio of severe dysneuria after 24 hours ischemic reperfusion in all medicated groups was obviously lower than that in control group(P ＜ 0.01),and the ratio in No.4 medicated group was lower than that in No.2 medicated group(P ＜ 0.05).② Comparison of water contents in brain of rats in each group:The water contents in sham operation group and all medicated groups were obviously lower than that in control group (P ＜ 0.05). ③ Comparison of the nitric oxide concentration in cerebral homogenate of rats in each group: The concentration in sham operation group and all medicated groups were obviously lower than that in control group (P ＜ 0.01). The concentration in No. 3medicated group was obviously lower than that in No. 1 medicated group (P ＜ 0.05).The concentration in No.4 medicated group was obviously lower than that in No. 2 medicated group (P ＜ 0.01). ④ Comparison of the nitric oxide concentration in serum of rats in each group:The concentrations in sham operation group and all medicated groups were obviously lower than that in control group(P ＜ 0.01).The concentration in No.3 medicated group was higher than that in No. 1 medicated group (P ＜ 0.05). The concentration in No. 4 medicated group was higher than those in No. 2 and in No. 3 medicated groups (P ＜ 0.05). ⑤ Comparison of the levels of CRP in cerebral homogenate and serum of rats in each group: The levels in sham operation group and all medicated groups were lower than that in control group(P ＜ 0.05-0.01).The level in No.3 medicated group was lower than that in No. 1 medicated group (P ＜ 0.01). The level in No. 4 medicated group was lower than those in No. 2 and in No. 3 medicated groups (P ＜0.05-0.01).⑥ Comparison of the levels of C3 in cerebral homogenate and serum of rats in each group:The levels in sham operation group and all medicated groups were lower than that in control group (P ＜ 0.05-0.01). The level in No.3 medicated group was lower than that in No.1 medicated group (P ＜ 0.05). The level in No. 4 medicated group was lower than those in No. 2 and in No. 3 medicated groups (P ＜ 0.01). ⑦ Comparison of the levels of C 4 in cerebral homogenate and serum of rats in each group:The levels in sham operation group and all medicated groups were lower than that in control group (P ＜ 0.05-0.01). The level in No. 3 medicated group was lower than that in No. 1 medicated group (P ＜ 0.05). The level in No.4 medicated group was lower than those in No. 2 and in No. 3 medicated groups (P ＜ 0.01). ⑧ Comparison of the condition of cerebral edema of rats in each group:In control group there was obvious cerebral congestive edema,indicating an obvious infection;while in medicated groups the extent of cerebral edema was milder than that in control group.⑨ Changes of cerebral ultrastructure of rats in each group:The ultrastructure in sham group was normal. In control group, there obvious edema of cells, capillaries and sheaths in the marginal zone of cortex necrosis,and reduction of organelles of neuron. As well. In No. 3 and No. 4 medicated groups, the limits of cell membranes were clear, the structure was integral, the chondriosomes were rich and even in size,the medullated fibers were morphologically normal.And in No.1 and No.2 medicated groups the changes were between the twoCONCLUSION:① The scoring of dysneuria in rats was decreased after the blood-activating and stasis-resolving medicine was given,and it was lower in rats that were given a longer period of medication,indicating that the improved extent for dysneuria is related to prolonged medication.②The nitric oxide concentration of cerebral tissue in rats that recevied the blood-activating and stasis-resolving medicine was decreased, and the nitric oxide concentration of serum in the rats was increased,indicating that the blood-activating and stasis-resolving medicine can reverse the anomalies of nitric concentration in different tissues after ischemic reperfusion so as to reduce cerebralinjury.③ The levels of C3 and C4 of cerebral tissue and serum in rats that received the blood-activating andstasis-resolving medicine were obviously decreased,indicating that the medicine may reduce the cerebral injury through triggering complement system;and the CRP was also get decreased,further suggesting that the medicine can inhibiting infective reaction.④ The longer the period of medication,the milder the cerebral injury, and the dose of 2.5 g/L was better in effect.

BACKGROUND: It has been known that re-recovery of blood flow after cerebral ischema may aggravate brain injury. It has been verified in some researches that the components for activating blood circulation and removing stasis in Chinese herbs can resist cerebral ischemic reperfusion injury.OBJECTIVE: To observe 4 most basic Chinese herbs for activating blood circulation and resolving stasis [honghua (Flos Carthami), taoren (Semen Persicase), chuanxiong (Rhizoma ligustici Chuanxiong) and chishao (Radix Paeoniae Rubra)] as the exertive factors on their influences on immune index changes in IgG, C-reactive protein (CRP) and complements of serum and homogenate in brain tissue so as to verify their graded and time effects.DESIGN: Randomized control experiment and single blind method.SETTING: Guangzhou Red Cross Hospital and Department of Neurology of the Fourth Hospital Affiliated to Jina University.MATERIALS: The experiment was performed from January 2001 to Decemb er 2002 in Experimental Room of Traumatic Institute of Guangzhou Red Cross Hospital. Totally 138 SD female adult rats were employed, mass weighted varied from 280 to 300 g, provided from Experimental Animal Center of Guangzhou University of Chinese Medicine. Honghua (Flos Carthami), taoren (Semen Persicase), chuanxiong (Rhizoma ligustici Chuanxiong)and chishao (Radix Paeoniae Rubra)] were the concentrated granules individually. At the ratio of 1:1:1:2, they were prepared into 2.5 g/mL raw herbal decoction (huoxue huayu tang).INTERVENTIONS: Thread embolic method was used to prepare cerebral medium sized artery obstruction model in rats (reperfusion for 24 hours after cerebral medium sized artery obstruction for 2 hours). Totally 138 rats were randomized into 6 groups, 23 rats in each. Sham operation group: ligature was done in each vessel without blocking medium sized artery of cerebrum.First perfusion group: 30 minutes before operation, gastric peffusion was done with 2 g/kg huoxue huayu tang. Second peffusion group: 30 minutes before operation, gastric perfusion was done with 2.5 g/kg huoxue huayu tang. Third perfusion group: before operation, gastric perfusion was done with 2 g/kg huoxue huayu tang continuously for 7 days. Fourth perfusion group: before operation, gastric perfusion was done with 2.5 g/kg huoxue huayu tang continuously for 7 days. In the control, physiological saline of all of the groups, when rats woke up, after 24 hours reperfusion and 2 hours ischemia, neural functional deficits were evaluated (5-score system, 0-1:After 24 hours reperfusion, 10 rats were randomized from each group for determination of the contents of CRP in homogenate and serum, complehours reperfusion, 10 rats were randomized from each group. After anesthetized, they were sacrificed rapidly to collect brains. Dried over heat in oven at 110℃ till constant weight, the water content of brain tissue was domized from each group to observe ultrastructure of brain tissue under transmission electron microscope (TEM) of rats in each group.and homogenate, complement C3 and C4 as well as serum IgG in rats of of severe neural functional deficits after 24 hours ischemic reperfusion in rats of each peffusion group was lower remarkably than the control (P ＜ 0.01),in which, that in fourth peffusion group was lower than second group (13%,group and each perfusion group was lower than the control (P ＜ 0.05), in which, that in third peffusion group was lower than first group (P ＜ 0.01).ment C3: That in sham operation group and each perfusion group was lower sham operation group and each perfusion group was lower than the control ( P ＜ 0.01), in which, that in third perfusion group was lower than first group (P ＜ 0.01); That in fourth perfusion group was lower than second and group and each perfusion group was lower than the control (P ＜ 0.01), in which, that in fourth perfusion group was lower than second group(P ＜ 0.05).each perfusion group was lower than the control (t=5.626-17.929, P ＜ 0.01),in which, that in third perfusion group was lower than first group (P ＜ 0.01),complement C3 in brain homogenate: That in sham operation group and each perfusion group was lower than the control (P ＜ 0.05-0.01), in which, third perfusion group was lower than first group (P ＜ 0.01), that in fourth group brain homogenate: That in sham operation group and each perfusion group was lower than the control ( P＜ 0.05-0.01), in which, that in third perfusion group was lower than first group (P ＜ 0.01), that in fourth group was lower tissue: The inflammatory reaction in the control was obvious. Brain edema and pathological damage in perfusion groups were milder than the control.Ulztrastructure was normal in sham operation group. The edema was obvious in cells, capillaries and myelin sheath in cortical necrosis margin area and neuronal cell organs were decreased in the control. In third and fourth peffusion groups, cellular membrane was clear in boundary line,integrative in structure, rich in mitochondria and even in size and the morphology of medullated fibers was normal. The situation of first and second perfusion was between two of them.deficits in the evaluation of rats and the score with long medication was lower, suggesting that long medication can even better improve neural funcplement C3 and C4 in brain bomogenate and serum and decreases serum IgG content, explaining that the medicine alleviates brain tissue injury by startup complement system. The remarkable decrease of C-reactive protein further suggests the inhibition of such medicine on inflammatory reaction.jury is, and the better result is achieved at dosage of 2.5 g/L.

Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.
