Objective To investigate the clinical value of enhanced recovery after surgery (ERAS) in patients undergoing postoperative early enteral nutrition (EEN) with radical resection for hilar cholangiocarcinoma.Methods The clinical data of 48 patients with hilar cholangiocarcinoma who were admitted to the Drum Tower Clinical Medical College of Nanjing Medical University from July 2006 to September 2014 were retrospectively analyzed.All the 48 patients underwent radical resection for hilar cholangiocarcinoma,including 24 patients receiving postoperative EEN (EEN group) and 24 patients receiving total parenteral nutrition (TPN group).The serologic indices and liver function were detected regularly after operation.Ten percent of albumin (Alb) 10 g was administered by intravenous infusion when Alb ＜ 30 g/L.The indexes of all the 48 patients were compared in the 2 groups at postoperative day 3 and 7,including the serologic indices and liver function,the exhaust time,the volume of Alb infusion,the complications (incisional infection,abdominal infection,pleural effusion,peritoneal effusion and bile leakage) and the duration of hospital stay.The patients were followed up by outpatient examination and telephone interview till September 2014.The measurement data with normal distribution were presented as x ± s,comparison between groups and count data were analyzed using the t test and chi-squared test,respectively.Results Patients in the 2 groups were cured successfully and discharged,and no patient died perioperatively.Patients in the EEN group had a good tolerance for EEN and no occurrence of EEN-related complications was detected.The level of the GGT was (108 ± 73) U/L in the EEN group,which was significantly lower than (225 ± 121) U/L in the TPN group at postoperative day 3 (t =4.041,P ＜ 0.05).The level of the GGT was (142 ± 86) U/L in the EEN group,which was no significantly different from (183 ± 107)U/L in the TPN group at postoperative day 7 (t =1.477,P ＞ 0.05).The postoperative time to anal exsufflation and the duration of hospital stay were (73 ± 18) hours and (15 ± 4) days in the EEN group,which were significantly different from (97 ± 21) hours and (18 ± 4) days in the TPN group,and the volume of Alb infusion was (44 ± 29)g in the EEN group,which was significantly lower than (101 ± 92) g in the TPN group (t =4.295,2.615,2.916,P ＜ 0.05).All the 48 patients were followed up for 1 to 71 months (mediantime,10 months),no patients received reoperation or re-admitted to the hospital due to complications.Conclusion The application of postoperative EEN in enhanced recovery of patients undergoing radical resection for hilar cholangiocarcinoma is safe and effective,it could accelerate the recovery of enteral function,shorten the postoperative duration of hospital stay and reduce the supplement of extrinsic Alb,which is helpful for the fast recovery of patients.

OBJECTIVETo determine weather or not the mtDNA(4568) deletions in guinea-pig contribute to the development of presbycusis.

METHODSForty-four guinea-pigs were divided into 2 groups: group A (young control group, normal hearing, 22 guineas) and group B (aged group). The group B was subdivided into group B(1) (old normal hearing, 6 guineas) and group B(2) (old hearing loss, 16 guineas). First the guineas were tested by auditory brainstem response (ABR), and then the Cortis's tissues, auditory nerve tissues, brain and blood were harvested and the total DNA was extracted. The mtDNA(4568) deletion was analyzed by PCR.

RESULTSHearing loss was occurred with age. The mtDNA(4568) deletion incidence of aged group in all tissues was significant higher than that of young control group (P< 0.05). The incidence of mtDNA deletion in Cortis's and auditory nerve with presbycusis (B(2) group) were significant higher than that of aged normal hearing group (B(1) group) (P< 0.05). The incidence of mtDNA deletion in brain and blood was not significantly different between presbycusis and aged normal hearing group (P> 0.05).

CONCLUSIONmtDNA(4568) deletion of guinea-pig possibly contributes to aging and mtDNA(4568) deletion in Cortis's and auditory nerve tissues of guinea-pig may be associated with presbycusis. There is no enough evidence to prove that the mtDNA(4568) deletions in brain and blood are related with presbycusis.

Objective:To observe the effects of electroacupuncture (EA) of three different frequencies (2 Hz,80 Hz and 2 Hz/80 Hz) on the free radicals in hippocampus of vascular dementia (VD) model mice.Methods:A total of 100 Kunming mice were randomly divided into a sham operation group,a model group,a 2 Hz EA group,an 80 Hz EA group and a 2 Hz/80 Hz EA group,with 20 mice in each group.The ischemia-reperfusion VD model was established by repeated blockade of bilateral common carotid arteries.Mice in EA groups began EA treatment on the 4th day after the operation.Baihui (GV 20),Dazhui (GV 14),Geshu (BL 17) and Zusanli (ST 36) were punctured and then connected to EA instrument,with different waves of 2 Hz,80 Hz or 2 Hz/80 Hz (10 min/time) applied accordingly,once a day.During the jumping stand experiment,the learning performance,memory performance and hippocampal calcitonin gene-related peptide (CGRP),nitric oxide synthase (NOS),malondialdehyde (MDA),changes in superoxide dismutase (SOD) and true choline esterase (TChE) were observed.In hippocampus,the CGRP level was determined by radioimmunoassay;the MDA level was determined by thiobarbituric acid colorimetric method;the activities of NOS and TChE were determined by spectrophotometry;the activity of SOD was determined by xanthine oxidase method.Results:Compared with the sham operation group,the performances of learning and memory decreased significantly in the model group (P＜0.01);in hippocampus,the CGRP level decreased,the MDA level increased,the activities of NOS and TChE increased,and the activity of SOD decreased in the model group.Compared with the model group,the learning and memory performances of the EA groups were significantly improved (P＜0.05 or P＜0.01);in hippocampus,the CGRP level increased,the MDA level decreased,the NOS and TChE activities decreased,and the SOD activity increased (P＜0.05 or P＜0.01).Among EA groups,the 2 Hz/80 Hz EA group was superior to the 2 Hz EA group and the 80 Hz EA group (P＜0.05 or P＜0.01).Conclusion:EA can improve the cognitive impairment of mice with ischemia-reperfusion VD.The mechanism may be related to the improvement of cerebral blood circulation,regulation of the central neurotransmitters,fighting lipid peroxidation and promoting nerve cell repair.The therapeutic effects of EA with different frequencies were different,and the intervention effect by EA at 2 Hz/80Hz is the most significant.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

BACKGROUNDSurgical interventions for moyamoya disease include direct and indirect revascularizations. This study aimed to evaluate the therapeutic effect of superficial temporal artery-middle cerebral artery bypass combined with an indirect revascularization procedure, encephalo-duro-myo-synangiosis, in the treatment of moyamoya disease.

METHODSFrom October 2005 to November 2009, we performed this combined revascularization procedure in 111 patients with different types and stages of moyamoya disease. The superficial temporal artery, middle meningeal artery and the deep temporal artery were evaluated for individualized surgical planning in these cases. The integrity of the deep temporal artery and the middle meningeal artery network, and the pre-existing spontaneous anastomoses of the distal branches of the external carotid artery with the cortical arteries were well preserved. The mean follow-up time was 72.5 months, all clinical and radiological data were retrospectively reviewed.

RESULTSA total of 198 stomas were performed in 122 hemispheres, all remaining patent until the last follow-up. The encephalo-duro-myo-synangiosis resulted in extensive anastomoses of the deep temporal artery (100%), the middle meningeal artery (90.9%), and the sphenopalatine artery (39.8%) with the cortical arteries, respectively. The superficial temporal artery, deep temporal artery, and the middle meningeal artery were significantly thickened in 88 patients as determined by digital subtraction angiography at follow-up. The relative cerebral blood flow increased significantly within one week after the operation. At 6 months post the operation, the relative cerebral blood flow was further increased by 15.5% from the gradual formation of anastomoses as a result of indirect revascularization. Transient ischemic attacks were effectively reduced or totally arrested. The neurological deficits significantly improved in 37 patients, with the National Institutes of Health Stroke Scale scores lowered by 2-8. There was no rehemorrhage in hemorrhagic moyamoya disease patients.

CONCLUSIONThis study showed that the superficial temporal artery-middle cerebral artery bypass combined with encephalo-duro-myo-synangiosis can achieve good therapeutic effect in the treatment of moyamoya disease.

OBJECTIVETo evaluate the impact of different gastrectomy and reconstruction method on prognosis and quality of life in proximal gastric cancer.

METHODSThe 265 cases of proximal gastric cancer received radical resection, according to gastrectomy or reconstruction method, were divided into proximal gastrectomy/gastroesophagostomy group (PG) (n = 63) and total gastrectomy/esophagojejunostomy group (TG) (n = 202). The clinical pathologic features, prognosis, postoperative quality of life in 2 groups were compared.

RESULTSThere had no significant differences in age, gender, CEA value between two groups (all P > 0.05). In PG and TG group, tumor size (cm), ratio of organic invasion, lymph nodes metastasis, distal metastasis, TNM IV stage, Borrmann typing, poor or undifferentiated carcinoma was 2.9 ± 1.9 vs. 4.8 ± 2.8, 9.5% vs. 32.2%, 64.7% vs. 70.6%, 0 vs. 8.4%, 6.9% vs. 31.8%, 44.4% vs. 69.2%, 31.7% vs. 53.7%, respectively, all with significant difference (t = -6.260, χ(2) = 29.473, 14.559, 5.665, 32.483, 12.588, 10.954, all P < 0.05). In PG and TG group, the ratio of D3 and D3(+) resection, multi-visceral resection, complications was 0 vs. 13.8%, 9.5% vs. 38.6%, 7.9% vs. 1.5% respectively, showed increasing range of resection and decreasing complications significantly in TG group (all P < 0.05). The median survival time (months) was 62.5 vs. 78.9 in TG and PG group respectively, without significant difference (P > 0.05). In 2 groups, the evaluation index of post-operative quality of life without significant differences (P > 0.05).

CONCLUSIONSFor proximal gastric cancer, although the cases received TG with worse clinicopathological features, which prognosis was similar to that received PG. The postoperative quality of life without significant difference between the cases received gastroesophagostomy and esophagojejunostomy.

OBJECTIVETo explore the impact of clinicopathological features and extent of lymph node dissection on the prognosis in early gastric cancer (EGC) patients.

METHODSA total of 142 EGC cases screened from database of gastric cancer of Sun Yat-sen University, from Aug. 1994 to Jan. 2010, were included in this study. According to the lymph node metastasis status, they were divided into lymph node negative (n = 116) and lymph node positive (n = 26) groups. The clinicopathological features of the two groups and the impact of extent of lymph node dissection on the prognosis were analyzed.

RESULTSThere were no significant differences in age, gender, tumor size and location, Borrmann typing, WHO TNM staging, histological typing, and CEA value between the two groups (P > 0.05). The TNM stages in the lymph node positive group were higher than that in the lymph node negative group (P < 0.001). Between the cases who underwent D1 (n = 21) and D2 (n = 121) dissection, there were no significant differences in postoperative hospital days, blood transfusion volume, and operation time (P > 0.05). The median numbers of LN dissected in D1 and D2 cases were 4 (0 to 16) and 20 (12 to 30), with a significant difference (P = 0.000), but the number of positive LN without significant difference (P = 0.502). The postoperative complication rates were 9.5% in the D1 and 3.3% in the D2 dissection groups, without a significant difference (P = 0.128). The median survival time of the lymph node negative and positive groups was 156 vs. 96 months (P = 0.010). In cases who received D2 and D1 lymph node dissection, the median survival time (MST) was 156 vs. 96 months (P = 0.0022). In the lymph node positive group, D2 dissection prolonged survival time significantly than D1 dissection (96 vs. 27months) (P = 0.001). Cox regression analysis showed that the extent of lymph node dissection and LN metastasis were independent prognostic factors for EGC patients.

CONCLUSIONSIt is not able to accurately assess the LN metastasis status preoperatively according to the routine clinicopathological features. For the patients with unknown LN metastasis status, D2 dissection should be the first choice. Comparing with D1 dissection, the morbidity of D2 dissection are not increased, but survival time is prolonged.

BACKGROUNDPancreaticogastrostomy (PG) has been proposed as an alternative to pancreaticojejunostomy (PJ), assuming that postoperative complications are less frequent. The aim of this research was to compare the safety of PG with PJ reconstruction after pancreaticoduodenectomy.

METHODSArticles of prospective controlled trials published until the end of December 2010 comparing PJ and PG after PD were searched by means of MEDLINE, EMBASE, Cochrane Controlled Trials Register databases, and Chinese Biomedical Database. After quality assessment of all included prospective controlled trials, meta-analysis was performed with Review Manager 5.0 for statistic analysis.

RESULTSOverall, six articles of prospective controlled trials were included. Of the 866 patients analyzed, 440 received PG and 426 were treated by PJ. Meta-analysis of six prospective controlled trials (including RCT and non-randomized prospective trial) revealed significant difference between PJ and PG regarding postoperative complication rates (OR, 0.53; 95%CI, 0.30 - 0.95; P = 0.03), pancreatic fistula (OR, 0.47; 95%CI, 0.22 - 0.97; P = 0.04), and intra-abdominal fluid collection (OR, 0.42; 95%CI, 0.25 - 0.72; P = 0.001). The difference in mortality was of no significance. Meta-analysis of four randomized controlled trials (RCT) revealed significant difference between PJ and PG regarding intra-abdominal fluid collection (OR, 0.46; 95% CI, 0.26 - 0.79; P = 0.005). The differences in pancreatic fistula, postoperative complications, delayed gastric emptying, and mortality were of no significance.

CONCLUSIONSMeta-analysis of six prospective controlled trials (including randomized controlled trials (RCT) and non-randomized prospective trial) revealed significant difference between PJ and PG regarding overall postoperative complications, pancreatic fistula, and intra-abdominal fluid collection. Meta-analysis of four RCT revealed significant difference between PJ and PG with regard to intra-abdominal fluid collection. The results suggest that PG may be as safe as PJ.

Background/Aims: Obstacles exist in facilitating hepatitis C virus (HCV) care cascade. To increase timely and accurate diagnosis, disease awareness and accessibility, in-hospital HCV reflex testing followed by automatic appointments and a late call-back strategy (R.N.A. model) was applied. We aimed to compare the HCV treatment rate of patients treated with this strategy compared to those without. Methods: One hundred and twenty-five anti-HCV seropositive patients who adopted the R.N.A. model in 2020 and another 1,396 controls treated in 2019 were enrolled to compare the gaps in accurate HCV RNA diagnosis to final treatment allocation. Results: The HCV RNA testing rate was significantly higher in patients who received reflex testing than in those without reflex testing (100% vs. 84.8%, P<0.001). When patients were stratified according to the referring outpatient department, a significant improvement in the HCV RNA testing rate was particularly noted in patients from non-hepatology departments (100% vs. 23.3%, P<0.001). The treatment rate in HCV RNA seropositive patients was 83% (83/100) after the adoption of the R.N.A. model, among whom 96.1% and 73.9% of patients were from the hepatology and non-hepatology departments, respectively. Compared to subjects without R.N.A. model application, a significant improvement in the treatment rate was observed for patients from non-hepatology departments (73.9% vs. 27.8%, P=0.001). The application of the R.N.A. model significantly increased the in-hospital HCV treatment uptake from 6.4% to 73.9% for patients from non-hepatology departments (P<0.001). Conclusions The care cascade increased the treatment uptake and set up a model for enhancing in-hospital HCV elimination.

Objective To investigate the prevalence and clinical features of human rhinovirus (HRV) infection in hospitalized children with acute respiratory (ARI) in eastern areas of Guangdong province from 2008 to 2010.Methods From Oct.2008 through Sep.2010,nasopharyngeal aspirates were collected prospectively,from hospitalized children with acute lower respiratory tract infection at the Second Hospital,affiliated to the Shantou University Medical College.Multiplex PCR was applied to detect ten kinds of viruses including HRV,RSV in the hospitalized children with respiratory tract infection.Clinical data on HRV-positive cases or RSV-positive cases were collected and analyzed.Results Among all the 1335 specimens,124 were confirmed as HRV-positive cases (9.3％),with IVA-positive rate as the highest (25.1％),followed by RSV-positive rate (15.1％).HRV infection occurred sporadically around the year,with the highest HRV-positive rate seen in spring 2009 and autumn in 2010.Symptoms,signs,chest X-ray,leukocyte count and CRP count did not differ between patients with co-infection or single HRV infection.Clinical symptoms or signs were similar between those with single HRV infection or single RSV infection in children,but the single RSV infected children were more frequently seen with wheeze and cough.28.4％ of the single RSV infected children had bronchiolitis while 10.7％ of single HRV infected children were seen (x2=0.281,P=0.596).Conclusion HRV was a relatively common cause for acute respiratory infections in the eastern areas of Guangdong province.The highest HRV-positive rate was slightly different in different years.Infants and young children were generally susceptible to rhinovirus infection.Bronchiolitis,wheeze and cough associated with HRV infection happened less than those caused by RSV.
