ObjectiveTo investigate the efficacy of laparoscopic hepatectomy for regional hepatolithiasis.MethodsThe clinical data of 81 patients with regional hepatolithiasis who received laparoscopic hepatectomy at the Southwest Hospital from March 2007 to March 2011 were retrospectively analyzed.Based on the classification of the Guideline for the diagnosis and treatment of hepatolithiasis 2007 version and indications for open surgery,hepatic lobes with calculi,biliary stricture or dilated bile ducts were resected laparoscopically after preoperative examination.Bile ducts of the remnant hepatic lobes were explored using fiber choledochoscope or electronic choledochoscope for the prevention of residual stones. Results Laparoscopic hepatectomy was successfully performed on 72 patients,and the other 9 patients were converted to open surgery. Left lateral lobectomy ( segments Ⅱ,Ⅲ ) was performed on 20 patients,left hemihepatectomy ( segments Ⅱ,Ⅲ,Ⅳ ) on 30 patients,right posterior lobectomy ( segments Ⅵ,Ⅶ ) on 11 patients,right anterior lobectomy ( segments Ⅴ,Ⅷ ) on 6patients,right hemihepateetomy (segments Ⅴ,Ⅵ,Ⅶ,Ⅷ ) on 9 patients,hepatic Ⅲ segmentectomy on 2 patients and hepatic Ⅵ segmentectomy on 3 patients.Gallbladders were resected,and intermittent portal triad clamping was performed on 15 patients.Hepateetomy combined with biliary exploration and stone removal was performed on 57 patients.The mean operation time and operative blood loss were (328 ± 80)minutes and (451 ±288) ml,respectively.No operative mortality was observed.Sixteen patients had postoperative complications,including pulmonary infection in 2 patients,pleural effusion in 4 patients,encapsulated effusion in the resection margin in 6 patients,abdominal infection and abscess in 2 patients and wound infection in 2 patients.Of the 16patients with complications,9 were cured by medicine,6 by pleural or abdominal drainage and 1 by wound debridement.The mean duration of hospital stay was ( 13 + 6)days.The intraoperative stone clearance rate was 96％ (69/72),and the residual stone in 3 patients were removed by choledochoscopy.Sixty-nine patients were followed up for 7-55 months,7 patients had symptoms of cholangitis and 2 patients had common bile duct stone recurrence.ConclusionsLaparoscopie hepatectomy is sate and effective for regional hepatolithiasis.Accurate positioning of the stones and lesions pre- and intra-operatively,reasonable designing of the parenchymal transection plane,and anatomical liver resection are the key points for achiving good therapeutic effects.

Objective To investigate the indications, techniques and results of laparoscopic hepatectomy. Methods The clinical data and follow-up results of 463 patients who received laparoscopic hepatectomy at our institute were retrospectively analyzed. Results From March 1, 2007 to March 31, 2011, 463 cases of laparoscopic hepatectomy were successfully carried out. Of the 463 patients,165 were with primary liver cancer, 29 with metastatic liver cancer, 143 with hepatic hemangioma, 81with hepatolithiasis and 45 with other benign liver diseases (including hepatic angiomyolipoma, hepatocellular adenoma, focal nodular hyperplasia and chronic liver abscess). The surgical approaches included laparoscopic left lateral lobectomy (93 cases), left hepatectomy (71 cases), extended left hepatectomy (4 cases), right hepatectomy (29 cases), right posterior lobectomy (24 cases), hepatectomy of segment Ⅵ (56 cases), extended right hepatectomy (2 cases), central hepatectomy (8 cases) and hepatectomy of segments Ⅶ/Ⅷ, Ⅳa, caudate lobe and the junction of segment Ⅵ and Ⅶ (41 case).Nonanntomic and wedge resection were performed on 121 patients, and combined resection on 14 patients. The mean operation time, blood loss, length of hospital stay and incidence of postoperative complications were (244.71 ± 105. 07) minutes, (460. 26±425.81) ml, (15.51 ±4.36) days and 9.29%, respectively. And no operative death occurred. In the 194 cases with malignant liver lesions,185 cases were followed up for 2 to 50 months. The 1 year and 3 year overall and disease free survival rate were 90. 8% and 87.9% , 84.2% and 73. 7% respectively. Conclusions As a means of minimally invasive surgical approach, laparoscopic hepatectomy can be selectively adopted for the treatment of all kinds of liver diseases which located at different parts of the liver, with the advantages of smaller trauma, quick recovery and cosmetic benefits. The short-term results of laparoscopic hepatectomy is superior to and its long-term results is equal to that of open surgery. Benign liver diseases, small hepatocellular carcinoma and metastatic liver cancer are the good indications for laparoscopic hepatectomy.

OBJECTIVETo explore the effects of uterine adenomyosis on the clinical outcomes of infertility patients treated with in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET).

METHODSA retrospective study was conducted of 61 IVF/ICSI-ET cycles as the study group, diagnosed with uterine adenomyosis by transvaginal ultrasound, and 164 IVF/ICSI-ET cycles of patients with tubal infertility as the control group. The baseline characteristics, ovary response and clinical outcomes were compared between the two groups.

RESULTSThe implantation rate, clinical pregnancy rate and live birth rate decreased significantly in the study group (P<0.05), and early abortion rate increased significantly (P<0.05). For patients with adenomyosis, GnRH-antagonist cycles tended to decrease clinical pregnancy rate and increase abortion rate (25.0% vs 45.0%, P=0.184; 66.7% vs 27.8%, P=0.247), and significantly decrease live birth rate (0% vs 30.8%, P=0.025), compared with GnRHa agonist cycles.

CONCLUSIONUterine adenomyosis decreases implantation rate, clinical pregnancy rate and birth rate, and increases abortion rate significantly in patients with IVF/ICSI-ET. GnRH-antagonist cycles have adverse effects on the outcomes of adenomyosis; GnRH agonist long protocol cycles may increase clinical pregnancy rate and decrease abortion rate.

Objective To evaluate the efficacy of double percutaneous nephrostomy combined with ureter occlusion stent in treating cervical cancer complicated with vesicovaginal fistula after radiotherapy. Method A prospective analysis was taken for 12 patients with cervical cancer complicated with vesicovaginal fistula after radiotherapy who were diagnosed by gynecological examination, imaging and cystoscopy. All patients received concurrent double percutaneous nephrostomy and ureter occlusion stent implantation.The improvement of symptoms and postoperative complications were observed.The number of white blood cells in urine,renal function,number of diapers in daily use(pieces),daily vaginal and urethral exudate, pain score,physical status (ECOG) score and quality of life score (KPS) before and 7 d after the procedure were compare by the paired Student's t test. Results Twelve patients were successfully implanted 24 ureter occlusion stents after successful nephrostomy. Postoperatively, urinary fistula immediately disappeared in all patients.One week after operation,bilateral hydronephrosis disappeared in 4 patients, renal insufficiency and renal function returned to normal in 4 patients. There were significant differences in the number of white blood cells in urine,the number of diapers in daily use,the daily vaginal and urethral exudate,pain score,KPS and ECOG score compared with before and 7 d after the procedure(all P<0.05).There was no significant difference in the creatinine and urea nitrogen (all P>0.05). No serious complications occurred after the operation.Conclusion Double percutaneous nephrostomy combined with ureter occlusion stent can effectively and safely treat cervical cancer complicated with vesicovaginal fistula after radiotherapy.

Objective: To investigate the status of insomnia, Internet addiction, and depressive symptoms among medical students and to analyze the effect of Internet addiction on insomnia and the mediating role of depressive symptoms, in order to provide a basis for the development of targeted interventions and measurements for medical students. Methods: A stratified whole group sampling method was used to select full-time college students from three medical universities in Anhui Province. The Chinese version of Insomnia Severity Index (ISI), Internet Addiction Test (IAT) scale and 9-item Patient Health Questionnaire (PHQ-9) were used to evaluate the symptoms of insomnia, Internet addiction and depressive in students. A multivariate Logistic regression analysis was used to explore the factors influencing insomnia among medical students and to analyze the relationship between insomnia with Internet addiction and depressive symptoms, respectively. Results: The overall rate of Internet addiction was 49.5%, depressive symptoms was 39.5%, insomnia was 18.6%. High academic stress, and the presence of surrounding people diagnosed with COVID-19 were associated with a higher risk of insomnia ( P <0.05). The higher the level of Internet addiction (mild, OR =2.60; moderate/severe, OR =4.21) and depression. (mild, OR =6.35; moderate/severe, OR =19.32), the higher the risk of insomnia. Mediated effect analysis showed that Internet addiction had a direct predictive effect ( β =0.02, P <0.05) on insomnia and also indirectly affected insomnia through depression (indirect effect=0.07，95% CI =0.06-0.08). Conclusion The detected rates of insomnia, Internet addiction and depressive symptoms are high among medical students in Anhui Province, and Internet addiction and depressive symptoms are risk factors for insomnia, which should be given more attention and appropriate interventions when necessary to improve their physical and mental health.

The clinical data of a 64-year-old patient with adrenocortical adenoma complicated with inferior vena cava tumor thrombus(IVCTT) were retrospectively analyzed. The patient was admitted becourse of intermittent dizziness for 4 months. CT examination revealed right adrenal tumor, and IVCTT was found in operation. Adrenal cortical adenoma needs to be distinguished from adrenal cortical carcinoma pathologically. Preoperative color Doppler ultrasonography, CT angiography or inferior vena cava angiography can confirm the diagnosis of IVCTT and tumor thrombus grade, and different surgical methods should be selected according to tumor thrombus grade.

Objective: To investigate the effects and underlying mechanisms of aspirin on endoplasmic reticulum stress in podocytes induced by hyperlipemia. Methods: Cultured podocytes were divided into four groups: control group, aspirin (100 μg/ml) group, oxidized low density lipoprotein (ox-LDL, 100 μg/ml) group, aspirin+ox-LDL group. The expression of protein kinase R-1ike endoplasmic reticulum kinase (PERK), eukaryotic translation initiation factor 2α (eIF2α), activating transcription factor-4 (ATF4) and CAAT/enhancer binding protein homologous protein (CHOP) at 6 h, 12 h, 24 h, 48 h were evaluated by real-time PCR. The related proteins of p-PERK and p-eIF2α at 24 h and ATF4 at 12 h were evaluated by Western blotting, respectively. Results: The expressions of PERK, eIF2α peaked at 24 h, while ATF4 and CHOP peaked at 12 h in ox-LDL group and aspirin+ox-LDL group. Compared with control group, the expressions of PERK, eIF2α, ATF4 and CHOP were significantly higher in ox-LDL group at each times (all P<0.05). Compared with ox-LDL group, the expressions of the above indicators were significantly lower in aspirin+ox-LDL group at each times (all P<0.05). At 24 h, compared with control group, the expressions of p-PERK and p-eIF2α were significantly higher in ox-LDL group (both P<0.05). Compared with ox-LDL group, the expressions of p-PERK and p-eIF2α were significantly lower in aspirin+ox-LDL group (both P<0.05). At 12 h, the expression of ATF4 protein in each group was similar to that of mRNA. There were no significant difference in the expressions of all indicators between aspirin group and control group. Conclusions Hyperlipidemia may cause endoplasmic reticulum stress in podocytes by inducing phosphorylation of PERK and eIF2α, activating ATF4 transcription and inducing high expression of CHOP. Aspirin may partially block the PERK pathway, which may have protective effects for podocytes.

BACKGROUND: TRIM proteins are important members of E3 ubiquitin ligases, and many studies have confirmed that TRIM family members play an important role in the development of various tumors. We found that TRIM59 expression level in non-small cell lung cancer (NSCLC) was significantly increased through second-generation sequencing. The purpose of this study was to investigate the expression of TRIM59 in NSCLC and its relationship with the clinicopathological parameters as well as the prognosis of patients. METHODS: The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets were excavated to analyze the expression of TRIM59 mRNA in NSCLC and its relationship with the prognosis of patients; The expression of TRIM59 protein in 90 tumor tissues and adjacent tissues was detected by immunohistochemical staining, and the relationship between the expression of TRIM59 protein and clinicopathological parameters and prognosis was analyzed. RESULTS: Overexpression of TRIM59 mRNA in tumor tissues predicted poor prognosis. The expression level of TRIM59 protein was significantly higher in tumor tissues than in adjacent tissues, and TRIM59 protein expression was correlated with tumor size (P=0.007), tumor differentiation (P=0.009), tumor-node-metastasis (TNM) stage (P=0.003) and lymph node metastasis (P=0.003). Multivariate Cox regression analyses showed that along with TNM stage, overexpression of TRIM59 could be considered an independent prognostic factor for NSCLC patients. CONCLUSIONS The expression of TRIM59 is closely related to the prognosis of NSCLC patients, and it is an independent risk factor for NSCLC patients.

Objective: To assess the incidence and related risk factors of postoperative intraabdominal infection in patients undergoing anatomical hepatectomy. Methods: The clinical data from 122 patients who underwent anatomical major hepatectomy in our institution were retrospectively analyzed. The electronic medical data were retrieved for further analysis including the amount of crystalloid and colloid fluid infused, intraoperative estimated blood loss, volume of blood transfusion, the dosage of vasoactive drugs, postoperative liver function, inflammation index, the incidence of intraabdominal infection and the length of hospital stay (LOS). Results: Patients were divided into infection group (n=39) and non- infection group (n=83). Intraabdominal infection was correlated with preoperative cirrhosis, the elevated direct bilirubin and alanine aminotransferase, the duration of operation, bilioenteric anastomosis or cholangiotomy, the infusion volume of colloid and crystalloid fluid, transfusion volume, direct bilirubin level on the POD 1(post-operation on day 1) (P<0.05); Multivariate analysis showed the incidence of intraabdominal infection was highly correlated with the amount of intraoperative colloid fluid bilioenteric anastomosis(P<0.05). Conclusions Intraoperative infused volume of synthetic colloid, along with bilioenteric anastomosis are independent risk factors for postoperative intraabdominal infection.
