Objective To analyze the efficacy of different treatment methods for end-stage hepatic alveolar echinococcosis combined with obstructive jaundice.Methods A retrospective study was conducted on the diagnosis and treatment of 55 patients with end-stage hepatic alveolar echinococcosis combined with obstructive jaundice managed from January 2000 to January 2013 at the First Affiliated Hospital of Xinjiang Medical University.The patients were divided into two groups according to the treatment options:group A,the palliative surgery group (n =38,69.1％) using palliative resection and biliary decompression ; and group B,the interventional group (n =17,30.9％) using percutaneous transhepatic cholangial drainage (PTCD).We analyzd the general data,preoperative and postoperative liver function,operation time,blood loss,average hospital stay,duration of postoperative tube drainage of abscess cavity,degree of lesion with invasion into the first porta hepatis,progressive lesion,continuous invasion and/or distant metastasis,biliary complications,mortality,and cumulative survival rates.The t-test or t'-test was used to analyze continuous data and the chi-square test was used to analyze categorical data.Parallel log rank test and Kaplan-meier method were used to calculate survival rates in survival analysis.Results When compared with group B,group A had significantly longer operative time,more blood loss,and longer average hospital stay (P ＜0.05).The postoperative total bilirubin,direct bilirubin,γ-glutamyl transpeptidase and alkaline phosphatase,aspartate aminotransferase,alanine aminotransferase were significantly higher than in group B (P ＜0.05).The level of post operative albumin was lower in group A than in group B.The two groups of patients (A and B) had similar background including general data (gender,age,nation),preoperative liver function,duration of postoperative tube-drainage of abscess cavity,degree of lesion-invasion into first porta hepa tis,progressive lesion-invasion and/or distant metastasis,biliary complications,mortality,cumulative survival rates and survival curves.Conclusions Interventional treatment is an effective treatment for end-stage hepatic alveolar echinococcosis combined with obstructive jaundice.It has the advantages of minimal invasiveness,simplicity,safety and repeatability.It may replace traditional palliative surgery in the future.

Objective To analyze the use of multidisciplinary team approach (MDT) for advanced and refractory hepatic alveolar echinococcosis in individualized treatment.Methods A retrospective study was conducted on the use of multidisciplinary team approach in individualized diagnosis and treatment for 137 patients with advanced and refractory hepatic alveolar echinococcosis (with invasion of major blood vessels and bile ducts,and/or with lung and brain metastasis) in our hospital from January 2005 to December 2013.The patients were divided into two groups:The MDT group (n =49) and the non-MDT group (n =88).The MDT group was further divided into two subgroups:subgroup A was the surgical treatment group (n =26),and subgroup B was the non-surgical treatment group (n =26).In the subgroup B,13 patients underwent late radical surgery.The non-MDT group was also further divided into two subgroups:subgroup a was the surgical treatment group (n =61),and subgroup b was the non-surgical treatment group (n =27).In subgroup b,5 patients underwent late radical surgery.The time taken to confirm the diagnosis,perioperative hospital stay,operation time,blood loss,postoperative drainage time,postoperative hospital stay,early postoperative complications (pleural and peritoneal effusions,bile leak,anastomotic leak),late postoperative complications (jaundice,anastomotic stenosis,recurrence),and rates of radical surgery were compared between subgroup A and subgroup a.The rates of late radical resection were compared between subgroup B with subgroup b.All data were analyzed using the Mann-Whitney rank sum test or the Chi-square test.Results Subgroup A had significantly shorter perioperative hospital stay,postoperative hospital stay,and total length of hospital stay than subgroup a (P ＜ 0.05).The incidence of late postoperative complications (jaundice,anastomotic stenosis,recurrence) was also significantly less than subgroup a (P ＜ 0.05),and the radical surgery rate was significantly higher than subgroup a (P ＜ 0.05).There was no significant difference in the time taken to confirm the diagnosis,operation time,blood loss,postoperative drainage time,early postoperative complications (pleural and peritoneal effusions,bile leak,anastomotic leak) (P ＜ 0.05) between subgroup A and subgroup a.The ratio of subgroup B receiving chemotherapy alone or drainage + chemotherapy,and the rate of late implement of radical resection were significantly higher than subgroup b (P ＜0.05).Conclusions A multidisciplinary team approach in individualized treatment comprehensively combined the advantages of the effects of drugs,intervention,surgery and systemic nutritional support.The best individualized treatment plan could be used which improved the rates of radical surgery in advanced and refractory hepatic alveolar echinococcosis,reduced postoperative complications,improved quality of life,and offered chances of radical resection in the patients who had lost the opportunities for surgery.

Objective:To investigate the changes of natural killer (NK) cells, natural killer T (NKT) cells and T lymphocytes in the peripheral blood after nanosecond pulse ablation of hepatic vesicular hydatid in rats with different energy levels.Methods:A total of 32 SD rats were randomly divided into hepatic vesicular hydatid model group, low voltage group (1 000 V), medium voltage group (1 500 V) and high voltage group (2 000 V). The hydatid model of rats was established by selective injection of 100 μl of echinococcosis head suspension with concentration of 500/100 μl into the left hepatic portal vein in all the 4 groups. After 3 months, nanosecond pulse therapy was applied to the left lobe vesicular hydatid lesions in the low voltage group, medium voltage group and high voltage group. On the third day after treatment, flow detector was used to calculate the ratio of CD 4+ T to CD 8+ T in peripheral blood of four groups by CD 3+ T, CD 4+ T, CD 8+ T, NK cells and NKT cells. Results:CD 3+ T was expressed in the high voltage group with (62.08±2.75)%, the medium voltage group with (63.84±7.73)%, the low voltage group with (55.19±8.55)% and the control group with (54.76±8.28)% ( P<0.05). CD 4+ T number was larger in high voltage group (43.7±6.51)% than medium voltage group (38.82±5.47)%, low voltage group (37.31±6.96)% and model group (38.12±3.04)% ( P<0.05). CD 8+ T ratio in the high voltage group was (20.03±2.40)%, the medium voltage group was (21.22±1.74)%, the low voltage group was (19.00±3.06)%, and the model group (20.56±3.98)%, with no statistically significant difference ( P>0.05). NK cells ratio in high voltage group was (6.49±1.60)%, medium voltage group was (3.02±0.32)%, low voltage group was (3.42±0.91)% and model group was (3.44±0.55)% ( P<0.05). NKT cells ratio in high voltage group was (1.53±0.16)%, medium voltage group was (0.82±0.09)%, in low voltage group was (0.70±0.17)% and model group (0.78±0.10)% ( P<0.05). CD 4+ T/CD 8+ T high voltage group was (2.26±0.65), medium voltage group was (1.90±0.40), low voltage group was (1.98±0.37) and model group was (2.06±0.35) ( P<0.05). Conclusion:High voltage (2 000 V) increased number of T, NK and NKT cells in peripheral blood compared with medium voltage (1 500 V) and low voltage (1 000 V), which may be the immune response of the body caused by nanosecond pulse ablation of hepatic vesicular hydatid in rats.

Objective:To explore the curative effect of laparoscopic surgery for hepatic cysticercosis.Methods:Search the literature from February 2010 to February 2020 on literature platforms such as Wanfang Data, VIP, CNKI, Pubmed, ScienceDirect, Web of Science, etc. the key words were "肝囊型包虫病" , "细粒棘球蚴" , "手术" , "开腹手术" , "腹腔镜" , "微创手术" , " echinococcosis " , " liver or hepatic " , " laparoscopic or minimal invasive " . Data on intraoperative indicators (e.g., operation time, bleeding volume), postoperative complications, hospital stay, recurrence rate, etc. in the literature included in the study were extracted and meta-analyzed.Results:A total of 9 articles were included, including 2 prospective studies and 7 retrospective case-control studies. A total of 1031 patients were enrolled, including 272 in the laparoscopic group and 759 in the laparotomy group. The results of the meta-analysis showed that the total postoperative complication rate in the laparoscopic group was lower than that in the laparotomy group ( OR=1.64, 95% CI: 1.10-2.45, P<0.05). Incision-related complications in the laparoscopy group and laparotomy group the difference was statistically significant ( OR=2.81, 95% CI: 1.03-7.70, P<0.05), and the hospital stay in the laparoscopic group was shorter ( SMD=1.21, 95% CI: 0.47-1.96, P<0.05). There was no significant difference between the two groups in operation time, postoperative bile leakage, residual cavity infection and effusion, and postoperative recurrence rate ( P>0.05). Conclusions:Under the premise of strictly grasping the indication of laparoscopic surgery, the incidence of complications after laparoscopic surgery is low, the hospitalization time is short.

Objective To Compare the therapeutic effects of laparoscopic cholecystectomy (LC) + laparoscopic common bile duct exploration (LCBDE) and primary suture with endoscopic retrograde cholangiopancreatography (ERCP)/endoscopic sphincterotomy (EST) + LC for cholecystolithiasis combined with choledocholithiasis.Methods The clinical data of 144 patients with cholecystolithiasis and choledocholithiasis who were treated in First Affiliated Hospital,Xinjiang Medical University from Dec 2014 to Jan 2016 were retrospectively analyzed,72 cases being treated by LC + LCBDE (group A) and 72 cases by ERCP/EST + LC (group B).The hospitallization time,hospitalization costs and complication rate were compared between the two groups.Results There were no statistically differences in terms of incidence of postoperative complication (P ＞ 0.05) in two groups.However,hospital stay [(10.25 ± 1.26) d vs.(14.25 ± 1.50)d),P =0.006] and hospitalization costs [(19 600 ± 1 521) yuan vs.(23 931 ± 1 629) yuan,P =0.008] were in favor of LC + LCBDE group than those in ERCP/EST + LC group.Conclusions LC + LCBDE is better than ERCP/EST + LC in the treatment of gall stone and choledocholithiasis.

Objective To assess the safety and feasibility of ambulatory laparoscopic appendectomy (ALA) with the concept of enhanced recovery after surgery (ERAS).Methods The clinical data of patients with appendicitis undergoing surgical treatment in the First Affiliated Hospital of Xinjiang Medical University from August 2017 to August 2018 were retrospectively analyzed.Among 196 patients,100 cases received ambulatory laparoscopic appendectomy with ERAS (ERAS group) and 96 cases received conventional laparoscopic appendectomy (control group).The average length of hospital stay,hospitalization expenses,NRS pain score at 6 h,12 h,24 h after surgery,patient satisfaction,time of postoperative off-bed activity,time of gastrointestinal function recovery,and postoperative complications were compared between two groups.Results There were significant differences in average length of hospital stay [(36.5± 1.3) h vs.(74.5±4.4) h,t=80.986),hospitalization expenses[(9 617.5±637.5) Yuan vs.(13 740.1±640.6) Yuan,t=45.150],6 h NRS pain score[(3.4± 1.4) vs.(4.1±1.3),t=3.360],12 h NRS pain score(2.0±1.3 vs.2.5±1.1,t=-2.929),time of postoperative off-bed activity[(5.7 ± 0.9) h vs.(11.5 ± 2.0) h,t=26.237],time of gastrointestinal function recovery(6.8± 1.1) h vs.(12.2±2.3) h,t=20.341]and patient satisfaction [(95.6±3.0) vs.(90.5±4.9),t=-8.644]between ERAS group and control group (all P＜0.05).There was no significant difference in the NRS pain score at 24 h(1.0±0.7 vs.1.0±0.8,t=0.287)and postoperative complications (x2=0.025)between the two groups (P＞0.05).Conclusion The ambulatory laparoscopic appendectomy with enhanced recovery after surgery is safe and feasible,with the advantages of low hospitalization cost,short hospitalization time,and high patient satisfaction.

Objective To evaluate the application value of preoperative computed tomography (CT) and three-dimensional reconstruction (3DR) of major vessels regarding lesion infiltration severity,vascular morphology & function and predict vascular surgeries during ex vivo liver resection and autotransplantation (ELRA) for end-stage hepatic alveolar echinocoecosis (AE).Methods Preoperative radiological & angiographical,intraoperative photographic and pathological materials were retrospectively collected in 40 consecutive patients undergoing ELRA for end-stage hepatic alveolar echinococcosis from January 2017 to January 2019.Severity of lesion infiltration,morphological & functional status as well as predictive value for surgical planning of hepatic venous system (HVs),inferior vena cava (IVC),portal venous system (PVs) and hepatic arterial supply system (HAs) were estimated,then compared with those built golden standards:angiography,intraoperative diagnosis and pathological examinationss.Results Evaluation accuracy of CT and 3DR for lesion infiltration severity,vascular morphology & function and predicting vascular surgeries respectively were 68.1％,71.9％,78.9％ and 57.5％,89.2％,71.1％ and all paired data had statistical significance (all P＜0.05).Furthermore,CT had a higher certainty of predicting the use of vascular prosthesis during surgery than 3DR (77.5％ and 70.0％,P＜0.05).Conclusions Pre-ELRA CT is recommended for evaluating lesion infiltration severity and predicting corresponding vascular surgery.However,3DR has more certainty in evaluating vascular morphology & function.Furthermore,CT is more reliable than 3DR in predicting vascular prosthesis during ELRA.However,optional better solutions should be studied for higher assurance.

Objective Explore the feasibility and accuracy of using deep learning techniques for gender inference in panoramic dental radiography images of Chinese Han population.Methods A total of 10,600 OPG images from Han individuals aged 18 to 70(5,300 males and 5,300 females)were collected and randomly divided into training set,validation set,and test set in an 8:1:1 ratio.MobileNetV2,Swin Transformer Small,and Swin Transformer Tiny models were trained,and the classification performance of the models was evaluated and visually displayed using accuracy,F1 score,and Grad-CAM algorithm.Results The accuracy of MobileNetV2,Swin Transformer Small,and Swin Transformer Tiny models was 97.57%,95.13%,and 96.28%respectively,with MobileNetV2 model showing the best overall performance.The Grad-CAM algorithm revealed that male OPG images mainly focused on the left and right mandibular branches and alveolar bone,while female OPG images mainly focused on the maxillary sinus,left mandibular branch,and posterior alveolar bone.Conclusion This study demonstrates that the gender inference model based on deep learning techniques for OPG images of Chinese Han population has high accuracy and generalization ability,providing a new approach for forensic gender determination in forensic medicine.

Objective:To analyze the treatment and the impact of brain metastases on patients with hepatic alveolar hydatid disease.Methods:The data of 11 patients with hepatic alveolar hydatidosis with brain metastases treated at the First Affiliated Hospital of Xinjiang Medical University from January 2014 to December 2019 were retrospectively analyzed. There were 7 males and 4 females. The age range was 19~49 years, with an average of 34 years. Of 11 patients, 7 were treated with surgery combined with drugs and 4 with drugs only. Analyze the treatment and results of patients.Results:Of the 7 patients who were treated with surgery and drugs, 2 patients underwent hepatectomy. They were treated with regular postoperative oral medication and were well on follow-up. Three patients underwent only brain surgery. On follow-up from 1 to 3 years, one patient developed pneumonia with atelectasis, another patient developed ascites and jaundice with physical decline. The third patient was stable and had an independent life. Two patients underwent partial hepatectomy and hydatidectomy, with one patient requiring repeated hydatidectomies. On follow-up for one of these 2 patients for 5 years, the patient was home bound and could not take care of himself. The other patient was followed up for 3 years and was stable, alive and able of self-care. Four patients were treated with albendazole liposome, including one patient who developed ascites, a second one with weight loss, physical decline, limb edema and a third one with pleural effusion, pelvic effusion and pneumonia. These patients were still alive with improvement of symptoms on supportive treatment.Conclusion:The treatment of hepatic alveolar hydatidosis with brain metastases is still mainly surgery and anti-hydatid drugs. The prognosis of most patients was poor. The surgical principle is neurosurgery first, followed by surgery on liver, lung, spleen and other organs involved by hydatid disease.

Objective:To evaluate the safety and efficacy of endoscopic retrograde biliary drainage (ERBD) for acute obstructive suppurative cholangitis (AOSC) in the elderly.Methods:A retrospective analysis was performed on the clinical data of AOSC patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2018 to January 2020. Patients aged 75 years and over ( n=49) were assigned to the elderly group and patients under 75 years old were assigned to the control group ( n=63). General data, American Society of Anesthesiologists (ASA) grading, procedure-related indicators, incidence of postoperative complications and mortality were compared. Results:There were significant differences in age (82.6±5.1 years VS 64.6±4.5 years, t=19.98, P<0.001), albumin levels (29.1±5.9 g/L VS 34.6±8.8 g/L, t=-3.94, P<0.001) and ASA grade ( χ2=8.37, P=0.015) in the elderly group and the control group . The elderly group were accompanied by more basic diseases, i.e. hypertension [57.14% (28/49) VS 34.9% (22/63), χ2=5.51, P=0.019], coronary heart disease [55.1% (27/49) VS 27.0% (17/63), χ2=9.14, P=0.003], chronic obstructive pulmonary diseases/asthma [24.5% (12/49) VS 6.3% (4/63), χ2=7.41, P=0.006]. There were no significant differences in the operation time (31.4±8.1 min VS 30.4±8.0 min, t=-0.61, P=0.543) or hospital stay (6.1±1.7 days VS 5.7±1.4 days, t=1.35, P=0.182). The incidences of postoperative complications were 14.3% (7/49) in the elderly group and 12.7% (8/63) in the control group, showing no significant difference ( χ2=0.06, P=0.807). No ERBD-related death was observed in either group during hospital stay. Conclusion:For elderly patients with AOSC over 75 years old, emergency ERBD, which can quickly relieve the disease, is safe and effective. Advanced age is not an absolute contraindication for emergency ERBD.
