Objective To investigate the risk factors and incidence of gas-related complications in peroral endoscopic myotomy for easophageal achalasia.Methods Clinical data of 216 patients with achalasia treated by peroral endoscopic myotomy from August 2011 to November 2013 were collected.Potential risk factors for gas-related complications were analyzed by univariate and multivariate analysis.Results The incidence of gas-related complications was 10.2％ (22/216).Univariate analysis showed risk factors for complications were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,tunnel width ≤3 cm,degree of myotomy,and operation time (P ＜ 0.05),while multivariate analysis showed the risk factors were Sigmoid type esophagus,simple longitudinal incision for tunnel entry,and tunnel width ≤3 cm(P ＜ 0.05).Conclusion Simple longitudinal incision for tunnel entry,tunnel width≤3 cm and sigmoid type esophagus are risk factors of gas-related complications in POEM,while myotomy depth is not.

Objective To compare the efficacy and safety of full-thickness peroral endoscopic myotomy (POEM) and circular myotomy for patients with severe achalasia.Methods The clinical data of 123 patients with severe achalasia who were admitted to the Second Xiangya Hospital of Central South University from August 2011 to May 2013 were retrospectively analyzed.Seventy patients who received full-thickness POEM were in the full-thickness myotomy group,and the other 53 patieuts who received circular myotomy were in the circular myotomy group.The clinical efficacies and incidences of complications of the 2 groups were compared.Patients in the 2 groups were followed up at the out-patient department till May 2014.The consecutive measurement data were presented by (x) ± s and analyzed using thc t test; the non-consecutive data were presented by M (range) and analyzed using the Wilcoxon rank test.Data before and after operation were compared using the repeated measure of analysis of variance.The count data were analyzed using the chi-square test.Results All the patients successfully received POEM.The operation time of the full-thickness myotomy group and the circular myotomy group were (57 ± 8)minutes and (63 ± 12)minutes,with significant difference between the 2 groups (t =3.421,P ＜0.05).The incidences of complications of the full-thickness myotomy group and the circular myotomy group were 14.3％ (10/70) and 11.3％ (6/53),with no significant difference between the 2 groups (x2=0.234,P ＞0.05).Atotal of 119 patients were followed up,with the median time of 18 months (range,12-24 months).The Eckardt scores at postoperative month 6 and 12 were 0 (range,0-3) and 0 (range,0-3) in the full-thickness myotomy group,and 0 (range,0-2) and 0 (range,0-3) in the circular myotomy group,with no significant difference between the 2 groups (Z =0.525,1.476,P ＞ 0.05).The sussess rates of the full-thickness myotomy group and the circular myotomy group were 98.6％ (69/70) and 98.1％ (52/53),with no significant difference between the 2 groups (x2=0.040,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 of the full-thickness myotomy group and the circular myotomy group were (3.2 ± 0.3) cm and (3.4 ± 0.4) cm,with no significant difference between the 2 groups (t =1.927,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 and 12 were significantly lesser than (5.9 ± 1.0) cm and (5.9 ± 1.0) cm before operation (F =780.923,493.018,P ＜ 0.05).No recurrence was detected in the 2 groups during the follow-up.Conclusion The short-term efficacy and incidence of complications of full-thickness myotomy and circular myotomy are comparable,while the operation time of patients who received full-thickness myotomy is shorter.

OBJECTIVE: To analyze the clinical and genetic characteristics of a 46,XX case of testicular disease with prostate germ cell tumor and explore its pathogenesis. METHODS: The clinical features and pathological examination of the patient were reviewed, and the genetic basis was analyzed by chromosome karyotyping analysis and fluorescence in situ hybridization. RESULTS: The patient had slightly short stature, small testicles and large breast. Serum alpha fetoprotein was significantly increased, along with increased follicle stimulating hormone, luteinizing hormone and prolactine, and lower level of testosterone. The karyotype was 46,XX. Fluorescence in situ hybridization has identified the presence of SRY gene at the end of short arm of one X chromosome. The pathological diagnosis was primary germ cell tumor of prostate, mainly of yolk sac tumor type. CONCLUSION A rare case of 46,XX testicular disorder of sex development combined with germ cell tumor of the prostate was diagnosed, which has enriched the phenotype spectrum of the disease and provided clues for the treatment of the disease.

Background/Aims: Studies have shown that nucleos(t)ide analogue (NA) treatment can reduce the risk of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients, but it is unclear which NA is most effective. We performed a meta-analysis and systematic review comparing the efficacies of NAs in CHB patients. Methods: We searched literature databases for randomized controlled trials (RCTs) and observational studies that analyzed the hepatic biochemical response, virological response, seroconversion rate, drug resistance rate, and HCC incidence rate in CHB patients treated with NAs. Meta-analyses were performed with RevMan and Stata/SE software. Results: Twelve cohort studies and one RCT were selected, in which entecavir (ETV), lamivudine (LAM), telbivudine (LdT), and/or tenofovir disoproxil fumarate (TDF) were evaluated in CHB patients. The meta-analysis showed that ETV was superior to LAM with regard to the HCC incidence (p<0.001), biochemical response (p=0.001), virological response (p=0.02), and drug resistance (p<0.001), and ETV was superior to LdT with regard to the virological response (p<0.001) and drug resistance (p<0.001). We found no significant difference between ETV and TDF with regard to the HCC incidence (p=0.08), biochemical response (p=0.39), virological response (p=0.31), serological conversion (p=0.38), or drug resistance (p=0.95). NA-treated patients with pre-existing cirrhosis had a 5.49 times greater incidence of HCC than those without cirrhosis (p<0.001). Conclusions ETV or TDF should be used for long-term first-line monotherapy in CHB patients according to the current guidelines. Standardized protocols are needed for future studies of ETV and TDF to facilitate conclusive comparisons. Patients with cirrhosis are at significantly elevated risk for HCC, despite the benefits of NA treatment.

OBJECTIVETo investigate the effect of dexmedetomidine on oxygenation function in adult patients with balanced anesthesia by propofol-fentanyl under one-lung ventilation (OLV).

METHODSTwenty-two patients undergoing thoracic operation were randomly divided into the study group and control group, both receiving propofol and fentanyl balanced anesthesia. In the study group, additional infusion of dexmedetomidine (0.3 µg/kg loading dose, 0.3 µg·kg(-1)·h(-1) maintenance dose) was administered, and the patients in the control group received only normal saline. Arterial blood samples were obtained at 4 time points from each patient during anesthesia for blood gas analysis.

RESULTSIn the study group, the pH values remained stable, the oxygenation index tended to decline progressively, but the incidence of hypoxemia was low; in the control group, the pH value and oxygenation index both declined progressively with a higher incidence of hypoxemia.

CONCLUSIONDexmedetomidine can better maintain the oxygenation function of OLV patients in balanced anesthesia by propofol and fentanyl, and its mechanism may be related to the decreased dose of propofol used.

BACKGROUND:Periprosthetic fracture of the femoral of the knee after total knee arthroplasty is one of the common complications,and there is a lack of biomechanical research on the periprosthetic fractures of the femoral of the knee under different bone strength conditions.The three-dimensional finite element analysis can provide a biomechanical basis for clinical practice. OBJECTIVE:To investigate the biomechanical changes of anterior femoral notching after total knee arthroplasty under different bone strengths,and to provide a mechanical basis for the clinical prevention of supracondylar femoral periprosthetic fractures after knee arthroplasty. METHODS:The femoral CT data of healthy adults were obtained,and the three-dimensional model of femoral lateral replacement of the knee joint was established by Mimics,Geomagic studio,and Solidworks software.Anterior femoral notching models of different depths were constructed,and the models were imported into ANSYS software to analyze the changes of biological stress on the femoral condyle with different bone strengths and different anterior femoral notching depths.The stress changes of the femoral anterior condyle section after and before the filling of anterior femoral notching with bone cement were analyzed. RESULTS AND CONCLUSION:(1)Under any bone strength,the supracondylar stress increased with the depth of anterior femoral notching.In normal bone conditions,there was a stress abrupt change point when the anterior femoral notching depth was between 3 mm and 4 mm.In the case of osteoporosis,there was a stress abrupt point when the anterior femoral notching depth was between 2 mm and 3 mm.(2)When anterior femoral notching occurred during knee arthroplasty and the depth exceeded the thickness of the bone cortex,the supracondylar stress of the femoral gradually increased as the bone strength decreased.(3)The stress of the anterior femoral condyle section decreased when the model with an anterior femoral notching depth of 3 mm was filled with bone cement.(4)The results show that anterior femoral notching should be avoided during knee arthroplasty,especially in patients with osteoporosis.If anterior femoral notching occurs during surgery,bone cement can be used to evenly fill the anterior femoral notching to reduce the supracondylar stress of the femur and reduce the incidence of periprosthetic fractures of the femoral joint
