Objective To explore the clinical significance of application of trans-abdominal Heller combined with Dor fundoplication for esophageal achalasia in the elderly.Methods Clinical data of 9 patients with esophageal achalasia undergoing trans-abdominal Heller combined with Dor fundoplication from Oct.2009 to Dec.2013 were collected.The postoperative effects and complications were analyzed.Results The operations were successful in the 9 patients with no conversion to open operation and no complications.The maximum esophageal diameter was reduced to (1.94 ± 0.76) cm from (3.69 ±-1.34) cm (P＜ 0.05).Rest lower esophageal sphincter pressure declined by 12.18 mmHg in average (1 mmHg=0.133 kPa,P＜0.05).Dysphagia score fell to 2.49 points from 7.88 points (P＜0.05).There were no retrosternal pain and dysphagia,stenosis and food retention in the lower esophagus and cardia place,and obvious expansion in esophageal.There were statistically significant differences in the above indexes.Conclusions The trans-abdominal Heller combined with Dor fundoplication can significantly improve the symptoms of esophageal achalasia in elderly patients,and effectively prevent postoperative gastroesophageal reflux,and has the characteristics being minimally invasive and fast,and fewer complications.

Objective To evaluate the clinical value of cerebrospinal fluid ADA,IL-23 joint detection in the diagnosis of tuberculous meningitis related diseases.Methods 253 cases with tuberculous meningitis related diseases were selected as the research subjects.According to the diagnosis,they were divided into tuberculous meningitis group (meningitis group,138 cases ),tuberculous meningitis complicated with hydrocephalus group (hydrocephalus group,35 cases)and control group(80 cases).All patients after admission received lumbar puncture, the part of cerebrospinal fluid specimens were inspected,the cerebrospinal fluid ADA,IL -23 joint test was conducted.Meningitis group and hydrocephalus group were given anti -TB drugs (INH,RFP and PZA +sm ) combined with chemotherapy.3 months after treatment,the meningitis group and hydrocephalus group received lumbar puncture cerebrospinal fluid ADA,IL -23 joint test again.The levels of ADA,IL -23 in cerebrospinal fluid were compared.Results Before treatment,cerebrospinal fluid ADA,IL-23 levels in the meningitis group were (12.64 ± 5.54)u/L and (48.38 ±10.78)pg/mL,those in the hydrocephalus group were (15.81 ±6.92)u/L and (77.21 ± 13.42 mm)pg/mL,which in the control group were (3.21 ±2.20)u/L and (9.05 ±3.89)pg/mL,ADA,IL-23 levels in meningitis group and hydrocephalus group before treatment were significantly higher than the control group (F=117.24,724.97,P<0.001).Spearma analysis showed that each group of cerebrospinal fluid ADA and IL-23 had no correlation.After treatment,the cerebrospinal fluid ADA,IL-23 levels in the meningitis group were (3.79 ± 3.13)u/L and (13.46 ±6.62)pg/mL,which in the hydrocephalus group were (6.42 ±4.35)u/L and (25.42 ± 8.54)pg/mL,the meningitis group before and after treatment had statistically significant differences in cerebrospinal fluid ADA,IL-23 (t=16.34,32.43,all P<0.001);hydrocephalus group before and after treatment had statistically significant differences in cerebrospinal fluid ADA,IL-23 (t=6.80,19.26,all P<0.001 ).Conclusion Cerebro-spinal fluid ADA,IL-23 joint detection in the early diagnosis of tuberculous meningitis related diseases and clinical observation has high clinical value.

BACKGROUND:Traumatic soft tissue defects of the limbs are usual y accompanied with the exposure of tendon, joint capsule, bone or internal fixator, which can be reconstructed by skin flap. Previous research has shown that it is an important method to repair traumatic tissue defects with flaps. However, rarely research reports perioperative management about flap bed so far. OBJECTIVE:To explore the perioperative strategy for repairing traumatic soft tissue defects with revascularized flaps. METHODS:Total y 94 cases undergoing secondary skin flap repair were enrol ed. Intraoperative debridement using tourniquet was performed, and the wound was washed with mass of physiological saline. Whether the tissues, including bone, tendon, joint capsule and internal fixator, were reserved or not depended on their viability, and then the flaps were harvested to repair defects, and drainage was placed properly at last. RESULTS AND CONCLUSION:The flaps survived in al cases. Exudation occurred in 5 cases with the exposure of bone, and 28 cases with the exposure of tendon or joint capsule healed normal y. No complications were associated with the reservation of the internal fixators, but delayed-union occurred in three cases and nonunion in one case. These findings indicate that the perioperative treatment of the application of skin flap is worthy of attention. Careful debridement, advisable choice of the flap, efficient drainage and using antibiotic normatively are al keys. Treatment of the bone, tendon, joint capsule and internal fixator which are exposed should not only weigh the advantage and disadvantage, but also relax the indication of reserving them.

Objective To investigate the clinical efficacy of nifedipine sustained-release formulation(SR)and nifedipine controlled-release(GITS)in the treatment of essential hypertension.Methods 160 patients with essential hypertension were randomly divided into two groups.The SR group was treated with SR 20 mg twice a day;GITS group was treated with GITS 30 mg once a day.All patients were given ambulatory blood pressure monitoring(ABPM)and observed the 24-hour average blood pressure,heart rate,changes in the trough/peak(T/P)values,and adverse reactions before and after treatment in two groups.Results The T/P value of systolic blood pressure(SBP)and diastolic(DBP)in the GITS group was 68.5％,74.6％,respectively,which were higher than those of SR group(57.2％,61.1％)(x2=6.32,7.05,all P＜0.05);GITS group was significantly lower than the SR group in heart rate(t=4.17,P＜0.05);Adverse reactions between two groups had no significant difference(x2=0.16,P＞0.05).Conclusion SR and GITS can effectively lower blood pressure,but GITS is more efficient,stable,safe,small impact on the heart rate.

Objective To observe the therapeutic effects and comphcations of treatment by using transcatheter arterial chemombolization(TACE) combined with functional splenic embolization(FSE) on patients with primary hepatocelluar carcinoma (HCC) combinded with hypersplenism.Methods Eighty HCC patients with hypersplenism were randomly divided into two groups by computer program.Observation group was treated with TACE and FSE,while control group was treated by only TACE.The iodine oil deposition,blood routine parameters and related complications were observed.Results (1) After one-month' s treatment,abdominal CT scan showed that 38 cases(79.17％) of patients in the observation group and 27 cases (84.38％) of patients in control group had iodine oil deposition in over 50％ of the tumor area.(2) The white blood cell counting in observation group were (7.65 ± 2.3) × 109/L,(5.89 ± 1.9) × 109/L,(5.02 ± 1.7) × 109/L in the follow-up examination 1 week,1month and 3 month after splenic embolization,respectively,which were significantly increased from the preoperative level of (2.21 ± 1.1) × 109/L(P ＜ 0.05).Platelets counting were (93 ± 29)× 109/L,(127 ± 32) × 109/L and (119 ± 26) × 109/L in observation group at 1 week,1 month and 3 month after splenic embolization,respectively,which were significantly higher than the preoperative level of (39 ± 20)× 109/L (P ＜ 0.05).In the control group,there were no statistically significant difference between the preoperative and postoperative levels (P ＞ 0.05).(3) Both of the the two groups showed no serious complications.Conclusion TACE combined with FSE is a safe and an effective method to treat hypersplenism combined in HCC patients.

Objective To explore the expression change of intestinal epithelial tight junction (IJ)protein claudin-1 in mice with fulminant hepatic failure (FHF).Methods FHF was induced with a method that combined intraperitoneal injection of lipopolysaccharide (LPS,10 mg/kg) and D-galactosamine (GalN,800 mg/kg).Control saline (2 ml/kg,ip),LPS (10 mg/kg,ip) and GaIN (800 mg/kg,ip) were also detected.The effect of administration of anti-tumor necrosis factor alpha (TNF-α) IgG antibody (anti-TNF-α IgG,100 μg/per) on the level of TNF-α was assessed before administration of D-galactosamine/lipopolysaccharide.At the 2nd h,6th h,9th h,12th h,24th h after injection in FHF group,the 9th h after injection in control groups and 9th h after injection in anti-TNF-α IgG group,the mice were killed for the collection of large intestine specimens.Claudin-1 was analyzed with immunohistochemistry,Western blotting,and real-time quantitative PCR.Results Tight junction protein claudin-1 was localized along the apical region of the lateral plasma membrane representing the region of tight junctions in surface and crypt epithelial cells.Weakly distributed density of claudin-1 in intestinal mucosa was found in mice with FHF from the 9th h after injection.Compared to saline group,Western blotting analysis demonstrated markedly reduced claudin-1 expression in mice with FHF at the 6th h and 9th h after injection (6th h:0.8600±0.0208 vs 1.0,P ＜0.05; 9th h:0.6633 ±0.0328 vs 1.0,P ＜0.01).Furthermore,the expression of claudin-1 mRNA was markedly reduced at the 6th h,9th h,and 12th h after injection in mice with FHF (6th h:0.3067 ±0.1291 vs 1.0,P ＜0.05; 9th h:0.2233 ±0.1155 vs 1.0,P ＜0.01 ; 12th h:0.5275 ±0.1222 vs 1.0,P ＜0.05).Compared to saline group,no significant difference in claudin-1 expression was found with prophylactic treatment with anti-TNF-α-IgG antibody in mice with FHF at the 9th h after injection (protein:0.9533 ±0.0186 vs 1.0,P ＞0.05; mRNA:0.85 ±0.1437 vs 1.0,P ＞0.05).Conclusions The expression of tight junction protein claudin-1 was reduced at both protein and mRNA levels in intestinal epithelial cells that were induced by TNF-α in mice model of FHF.

Objective To investigate the relation between coagulation disorders and sepsis severity of infected patients.Methods In this retrospective study,75 patients,51 males,24 femalse,with age(55.8± 18.1),were included from January 2010 to March 2011.They were clinically diagnozed as infection,and had Thromboelastography(TEG)and routine coagulation test within 24 hours after admission to emergency department.They were divided into 3 groups based on SIRS and SOFA score within 24 hours after admission:a)infection group,patients without SIRS; b)sepsis group,patients with SIRS and SOFA score less than 5; c)severe sepsis group,patients with SOFA score greater than or equal to 5.LSD was used to compare between two groups if one-way ANOVA of three groups comparasion showed significant differences.Results In comparasion to sepsis group(n =29)and infection group(n =27),D-dimer elevated significantly in severe sepsis group(n =19)(F =3.388,P =0.004),and platelet count decreased significantly(F =3.839,P =0.026),INR and KPTT showed an increase trend without significant difference (F =2.657,P =0.077 ; F =2.782,P =0.069); TEG showed MA obviously decreased(F =5.841,P =0.004),while there were nostatistically significant differences among other data.Conclusions The extent of coagulation disorders and sepsis severity of infected patients is closely correlated to each other.

Objective To gain more pathophysiolgic knowledge about acute obstructive hydrocephalus and to explore its rapid and effective treatment by establishing canine acute obstructive hydrocephalus model.Methods Acute obstructive hydrocephalus model was established by injecting cyan-acrylic gel glue into the fourth ventricle via posterior fosse craniotomy in 9 male adult mongrel dogs.At the same time,lateral ventricle catheterization were performed and were fixed on the scalp to connect reservoir bag so that the changes of intracranial pressure (ICP) could be measured dynamically,and the changes of neurological function were observed.Results Acute obstructive hydrocephalus model was successfully established in 6 of the total 9dogs.ICP was (48.2 ± 6.1 ) cm H2 O at 48 hours after the injection and was (56.4 ± 5.7 ) cm H2 O at 72 hours after the injection,it increased 392％ and 459 ％ respectively.And the ICP after injection was significantly different(P ＜ 0.01 )compared with that before injection (12.3 ± 3.1 )cm H2O.Conclusion The establishment of acute obstructive hydrocephalus model has high success rate,and is easy to reduplicate; ICP could be measured dynamically and also could be reduced by releasing CSF;Thus,ventricular drainage is the most rapid and effective treatment for acute obstructive hydrocephalus.
