Objective To investigate the clinical effects differences of two kinds of D2 lymphadenectomy in the treatment of patients with advanced gastric cancer including open operation and laparoscopy operation.Methods 90 patients with advanced gastric cancer were chosen in recent years in our hospital and were randomly divided into both group including group A (45 patients)with D2 lymphadenectomy by open operation and group B (45 patients) with D2 lymphadenectomy by laparoscopy operation;and the clinical indicators in peri-operation period,the dissec-tion number of lymph node,survival rate in 1 year with follow-up and postoperative complication incidence of both groups were compared.Results The clinical indicators in peri-operation period of group B was significantly better than that of group A (t=2.13,2.56,1.98,1.96,1.94,2.05,2.10,all P<0.05).The N2 dissection number of lymph node of group B was significantly fewer than that of group A (t=2.15,P<0.05).The survival rate in 1 year with follow-up of group A and group B were separately 88.89%and 91.11%,there was no significant difference in survival rate in 1 year with follow-up between the two groups(χ2 =1.67,P>0.05).The postoperative complication incidence of group A and group B were separately 20.00% and 8.89%,the postoperative complication incidence of group B was significantly lower than that of group A (χ2 =9.44,P<0.05).Conclusion Compared with D2 lymph-adenectomy by open operation,D2 lymphadenectomy by laparoscopy operation in treatment of patients with advanced gastric cancer can efficiently decrease the degree of surgical trauma,accelerate the process of recovering after opera-tion,and be helpful to reduce the risk of postoperative complications.

Objective To evaluate video-assisted thoracoscopic sympathectomy(VTS) for the treatment of palmar hyperhidrosis(PH),and to analyze curative efficacies for surgeries on different sympathetic segments.Methods Medline search was done on PubMed and data of randomized controlled trials(RCTs) about comparisons of surgeries on different segments over the past decade were collected.According to the inclusion criterion,relevant articles were screened.Then we extracted data,assessed trail quality,and performed Meta-analysis by using RevMan 5.2 with postoperative compensatory hyperhidrosis(CH) as the main evaluation index.Results A total of 11 RCTs involving 1 413 patients were included,among which all patients underwent bilateral VTS.Ef cacious rates were similar between multiple and single ganglia sympathectomy(97.7％ vs 98.8％,P ＜0.01).However,single-ganglia group showed a lower risk of CH compared to multiple-ganglia group.Meta-analysis suggested that,in the subgroups of the single-ganglia VTS,no significant difference was found between T2/T3 and other segments in the risk of CH [T2 segment vs other segments,RR =1.11,95 ％ CI(0.99,1.24) ; T3 segment vs other segments,RR =0.99,95％ CI(0.89,1.11)].The risk of CH was significantly lower in T4 sympathectomy than in other segments [RR =0.67,95％ CI(0.57,0.79)].By comparison of T2,T3 and T4 sympathectomy,we found that low segment had a lower risk of CH than high segment[RR =0.75,95％ CI(0.68,0.84)].Conclusion Single-ganglia and low segment sympathectomy can significantly reduce the incidence of CH,and T4 is supposed to be the best segment for the treatment of PH.

Objective To explore the efficacy of sequential or combined amphotericin B (AmB) and fluconazole (FCZ) therapy on a 5 flucytosine based regimen in non-acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis.Methods A tatal of 117 cases of non-AIDS-related cryptococcal meningitis treated with 5-flurocytosine-based regimens were retrospectively divided into five groups:AmBgroup (n=38),FCZ group (n=25),FCZ and AmB sequential group (n=18),AmB and FCZ sequential group (n=15),AmB and FCZ combination group (n=21).The number in cerebrospinal fluid (CSF) of the five groups were compared.Statistical analyses included t test,oneway analysis of variance,K-independent samples test and chi-square test.Results Intracranial pressure of AmB group,FCZ group,FCZ and AmB sequential group,AmB and FCZ sequential group,AmBandFCZ combination group were (208.6±75.1),(191.5±94.5),(185.0±76.3),(201.9±69.7) and (223.1±89.3) mm H2O (1 mm H2O=0.0098 kPa),respectively,and the differences were not statistically significant (F=0.611,P =0.656).Median cryptococcus counts in CSF of the five groups were 0,10,0,3 and 0/mL,respectively,with no statistical significance (x2 =7.638,P-0.090).CSF protein levels of the five groups were 0.55,0.69,0.67,0.53 and 0.96 g/L,respectively,with no significant differences among groups (F=7.063,P=0.133).The cure rates of the five groups were 55.3％ (21/38),32.0％ (8/25),9/18,6/15 and 47.6％ (10/21),respectively;progression rates or mortality of the five groups were 28.9％ (11/38),44.4％ (11/25),5/18,4/15and 23.8％ (5/21),respectively; and the differences among cure rates (x2 =3.638,P=0.457) and progression rates or mortality (x2-2.785,P =0.604) were not statistically significant.Conclusion FCZ or AmB alone,sequential or combined therapy were all effective in the treatment of cryptococcal meningitis.

ObjectiveTo investigate the therapeutic effects of patients with non-acquired immunodeficiency syndrome ( AIDS )-related cryptococcal meningitis treated with fluconazole and flucytosine.MethodsA retrospective study was conducted including 52 cases of non-AIDS-related cryptococcal meningitis,which were divided into two groups:the amphotericin B combined with flucytosine group (n =32) and the fluconazole combined with flucytosine group (n =20 ). The comparison between groups was done by t test and chi-square test.ResultsThe intracranial pressure of the amphotericin B combined with flucytosine group and the fluconazole combined with flucytosine group were (221.9±76.2) and (213.4±99.2) mm H2O,respectively (t=0.302,P＞0.05) ; the cryptococcus counts in the cerebrospinal fluid (CSF) were (351 ± 1180) and (508 ± 943)/mL,respectively (t=- 0.473,P＞0.05) ; the CSF protein levels were (0.754 ± 0.726) and (0.649 ±0.308) g/L,respectively (t=0.578,P＞0.05) ; the CSF white blood cell (WBC) counts were (16±25) × 106/L and (28±32) × 106/L,respectively (t=-1.348,P＞0.05).The cured rates were 59.38％ (19/32) and 35.00％ (7/20),respectively in the amphotericin B combined with flucytosine group and the fluconazole combined with flucytosine group,and the improved rates were 6.25％(2/32)and 25.00％ (5/20),respectively,the uncured or mortality rates were 34.38％ (11/32) and 40.00％ (8/20),respectively,and the difference were not significant of cured rates (x2 =2.925,P＞0.05) and uncured or mortality rates (x2 =0.168,P＞0.05) between two groups.ConclusionFluconazole combined with flucytosine also has a good effect on the treatment of cryptococcal meningitis.

Objective To summarize the nursing experience of treatment of percutaneous and transhepatic portal venous autologous bone marrow stem cell transplantation for chronic hepatic failure.Methods 19 patients who were definitely diagnosed as chronic liver failure received pertinent nursing in different perioperative period of transhepatic portal venous autologous bone marrow stem cell transplantation.Results All of the 19 patients went through perioperative period safely without any adverse reactions or complications.Conclusions In the process of treatment of autologous bone marrow stem cell transplantation for chronic hepatic failure,sufficient preoperative preparation,good communication and close cooperation among doctors,nurses and patients during operation,careful nursing and rehabilitation instruction after operation,are important assurances for autologous bone marrow stem cell transplantation to run smoothly.

Objective To compare the efficacy of lymph nodes(LNs) dissection between video-assisted thoracic surgery (VATS) and thoracotomy in the treatment of clinical stage Ⅰ lung cancer.Methods A comprehensive search of PubMed,Ovid Medline,EMBASE,Web of Science,ScienceDirect,the Cochrane Library,Scopus database and Google Scholar was performed to identify studies comparing VATS and thoracotomy in LNs dissection.The data was analyzed by RevMan 5.3 software and SPSS 18.0.Results After selection,23 articles met the inclusion criteria.2 316 patients were involved in VATS group and 3 346 patients were involved in Open group.Meta analysis showed that less total LNs(95％ CI:-1.64--0.60,P ＜ 0.0001),totalLNsstations(95％CI:-0.61--0.01,P=0.04) andN1 LNs(95％CI:-0.28--0.02,P=0.02)were dissected in VATS group.On the left side,more LNs were dissected in VATS group(95％ CI:0.51-3.22,P =0.007).The same number of mediastinal LNs (95％ CI:-0.74-0.15,P =0.20),mediastinal LNs stations (95％ CI:-0.20-0.14,P =0.76),right side LNs (95 ％ CI:-1.52-2.23,P =0.71) were harvested in both groups.Conclusion In the surgical treatment of clinical stage Ⅰ lung cancer,less total LNs,total LNs stations and N1 LNs were dissected in VATS group,while more left side LNs were harvested by VATS.The same number of mediastinal LNs,mediastinal LNs stations right side LNs were harvested in the two groups.This conclusion still needs to be further proved by more high-quality and large-scale RCTs.

Background and purpose:Five-year survival rate of post-operation patients with non-small cell lung cancer(NSCLC)is less than 40%.Treatments after recurrence are difficult.Our study aimed to evaluate the efficacy of pemetrexed on postoperative recurrence of NSCLC.Methods:From Jan.2006 to Sep.2008,40 NSCLC with postoperative recurrence were observed.All patients had received pemetrexed(ALIMTA)500 mg/m2 or carboplatin eonbined.Results:Among the 40 patients,partial response in 10 patients(25.00%),stable disease in 19 patients(47.50%),progressive disease in 11 patients(27.50%).The total response rate was 25.00%and clinical benefit control rate was 72.50%.Pemetrexed had significantly better disease control rate in female than in male (9 1.30% vs 47.06%,P=0.034),in adenocarcinoma patients than in non-adenocarcinoma's(87.10% vs 22.22%,P=0.001).Median overall survival time(MST)was 10.70 months.Progression-free survival time(PFS)was 5.18 months.Adenocarcinoma patients had longer PFS than non-adenocarcinoma patients.Conclusion:Pemetrexed demonstrates significant antitumor activity and good tolerance in these patients.

Hepatitis E is a globally distributed infection that varies in seroprevalence between developed and developing regions.In the less developed regions of Asia and Africa,a high seropositivity rate has been reported for hepatitis E virus(HEV)antibodies.Although acute hepatitis E is often self-limited and has a favorable prognosis,some populations experience severe manifestations,which may progress to liver failure.Moreover,some immunocompromised patients are at risk of developing chronic HEV infection and cirrhosis.Proactive screening,reducing misdiagnosis,improving patient management,timely anti-viral therapy for severe and chronic cases,and vaccination of high-risk groups are important measures to reduce the morbidity of hepatitis E.This review focused on the clinical presentation,management,and prevention of hepatitis E.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9％)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6％.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of＞1000 IU/mL(33.3％vs.5.4％).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.
