ObjectiveTo find out the risk factors and the incidence of lithiasis. MethodsA questionnaire was formulated by the National Biliary Surgical Group. It was sent to the medical staff of all levels of hospitals in the Zunyi Region, Guizhou to fill in on surgically proven cases of cholelithiasis. The clinical data were collected and analyzed using SPSS 13.0. ResultFor lithiasis, the gender ratio was 1∶ 1.78; the peak age was 41-year and 51-year respectively. The proportion of cholecystolithiasis (n =4456 ; 86.76 ％) and choledocholithiasis (n =554;10.79 ％ ) was comparatively higher than in other regions in China. ConclusionsThe commonest type of lithiasis in Zunyi was cholecystolithiasis. There was an increasing tendency for lithiasis to develop in young people. Lithiasis was closely associated with factors such as gender, food and occupation.

Objective To assess the functional restoration in patients with developmental dysplasia of the hip (DDH) who underwent hip resurfacing arthroplasty and to determine whether greater abduction angle of the acetabular component is relat?ed to larger diameter of femoral head component. Methods We reviewed 34 DDH cases (9 hips of 8 males and 25 hips of 24 fe?males, mean age 44.6±11.85 years at the time of surgery) on whom we performed hip resurfacing arthroplasty (HRA) from October 2006 to September 2009. The total hip Arthroplasty (THA) group was consisted of 35 DDH cases (8 hips of 8 males and 27 hips of 25 females, mean age 43.7±10.4 years at the time of surgery). All operations were performed by the same doctor over the same peri?od. Assessment of the functional hip scores was conducted by Harris Hip Scores. A radiographic study was also performed to evalu?ate the implants stability and abduction angle of the acetabular components. All the data was analyzed with Kolmogorov?Smirnov method. Results The mean follow?up was 6.2 years in the HRA group. The Harris Hip Score improved from 54.9±13.2 to 97.3± 6.2 after the surgery. The mean abduction angle of the acetabular component was 51.6° ± 5.33°, hip flexion was 127° ± 6.9° and mean diameter of femoral head was 46.5±1.5 mm. The mean follow?up was 5.9 years in the THA group. The Harris Hip Score im?proved from 51.6±19.7 to 95.6±7.9 after the surgery. The mean abduction angle of the acetabular component was 43.9°±4.90°, hip flexion was 117°±4.2°. There was no failure of the prosthesis, peri?prosthetic fracture and infection in either group. There was sig?nificant difference in the abduction angle of the acetabular component (P<0.05) and flexion of the hip between the two groups (P<0.05). Conclusion Patients in the HRA group had a better functional restoration and larger range of motion. Furthermore, a larger diameter of femoral head component could be achieved by placing the acetabular component in a greater abduction angle, which may contribute to a better long?term stability.

Objective:To retrospectively analyze the efficacy of video-assisted thoracoscopic surgery (VATS) in the treatment of solitary pulmonary nodule (SPN) and related factors affecting the diagnosis of benign and malignant SPN.Methods:The clinical data and surgical conditions of 317 patients with SPN who were resected by VATS and diagnosed by pathology in Chaoyang Central Hospital from January 2017 to December 2019 were retrospectively analyzed.The patient′s surgical efficacy and corresponding imaging features were explored.Results:Of the 317 patients, 124 (39.1%) cases underwent uniportal VATS and 193(60.9%) cases underwent multi-portal-portal VATS, 195(61.5%) cases had lobectomy, 16(5.1%) cases had anatomical segmentectomy, and 106(33.4%) cases had wedge resection. The operation time of the whole group was 50 - 210 (146.5 ± 34.7) min, intraoperative blood loss was 10 - 180 (69.3 ± 31.5) ml, thoracic drainage tube retention time was 2 - 7 (3.7 ± 1.4) d, postoperative hospital stay was 3 - 21 (6.4 ± 1.8) d, and the complication rate was 1.0%(3/317). No perioperative death occurred. Among all the nodules, 98(31.0%) cases were benign nodules and 219(69.1%) cases were malignant. Multivariate analysis showed that maximum nodule diameter, lobulated sign, burr sign, vascular bundle sign and pleural sag sign were independent related factors for the diagnosis of benign and malignant nodules ( P<0.05). Conclusions:VATS has less trauma and fewer complications, which has important clinical value for the diagnosis and treatment of benign and malignant SPN. Nodule maximum diameter, lobulated sign, burr sign, vascular bundle sign, pleural pit sign are independent related factors that affect the diagnosis of benign and malignant SPN.

Objective To study the clinical value of retroperitoneoscope-assisted intraperitoneal approach in the treatment of large renal tumors.Methods A total of 89 patients with large renal tumors (d ＞7 cm) were involved from January 2014 to December 2017.Among them,32 cases were treated by retroperitoneoscope-assisted intraperitoneal approach (group A),including 18 males and 14 females,aged (63.5±7.5)years,with 20 cases on the left and 12 on the right,and mean tumor diameter of (7.9 ± 0.6).Thirty cases were treated by laparoscopy (group B),including 17 males and 13 females,aged (64.5 ±7.3)years,with 16 cases on the left and 14 cases on the right,and the average tumor diameter of (7.6 ±0.7) cm.Twenty-seven cases underwent open surgery (C group),including 15 males and 12 females,aged (64.9 ±5.7) years,with 13 cases on the left side and 14 cases on the right,and the average tumor diameter of (7.9 ±0.6) cm.There was no statistically significant difference among the three groups in term of demographics (P ＞ 0.05).The clinical data was collected and statistical analysis was made for comparison among the three groups,including operation time,blood loss,surgical complications,postoperative intestinal recovery and postoperative hospital stay.All the patients were with single renal tumor,and no other major comorbidities were found.Results All of the 89 surgeries were successful.Hypercapnia was found in 2 cases (6.3％) in Group A,and recoverd 15 minutes after stopping pneumoperitoneum and anesthesia.The operation time was 120-200 minutes with an average of (155.0 ± 22.1) minutes.The average amount of bleeding was (141.6 ± 33.8) ml.Bowel recovered 3 (3-5) days after operation.The patients were hospitalized for 7 (7-9) days.In group B,hypercapnia was found in 2 patients (6.7％) and recoverd after stopping pneumoperitoneum and anesthesia.The time of operation was (184.2 ± 20.6) min,the amount of bleeding was (191.5 ± 46.2) ml,the bowel recovered 4 (4-6) days after operation,and the postoperative hospitalization duration was 7.5 (6-9) days.The operation time of group C was (54.0 ± 16.6) min,blood loss was (309.6 ± 50.2) ml,postoperative intestinal recovery was 5 (4-6)days,and the postoperative hospitalization time was 8 (7-12)days.Group A had less operation time than Group B(P ＜0.05),and no difference with Group C(P ＞0.05).Group A had advantages in term of blood loss and postoperative intestinal recovery time compared with B and C (P ＜ 0.05).Groups A and B had no difference in term of surgical complications and postoperative hospital stay (P ＞ 0.05),but both of the two groups had obvious advantages over group C (P ＜ 0.05).Conclusions Retroperitoneoscopeassisted intraperitoneal approach is the synergetic application of two endoscopic approaches,which is superior to any single operation for the treatment of large renal tumor,such as less bleeding,shorter operation time,faster postoperative recovery,and so on.This method not only reduces the difficulty of operation,provides an alternative for laparoscopic treatment of large renal tumors,but also has a good application for complex renal tumors complicated with renal vein and inferior vena cava tumor thrombus.

Objective:To investigate the expression of IKBKE and NF-κB in pancreatic cancer, and to explore the effect of IKBKE on pancreatic cancer proliferation and migration.Methods:Immunohistochemistry staining was used to study the expression of IKBKE and NF-κB in tissues of 61 pancreatic cancer patients admitted to the Second Hospital of Tianjin Medical University from January 2012 to January 2017 and 13 normal pancreatic tissues. The correlations between those expression to clinicopathological features were analyzed. Lentivirus mediated RNAi was transfected into pancreatic cancer cells to block IKBKE. Western blot was performed to test the silencing effeciency; CCK-8 and plate clone and scratch assays were used to investigate the proliferation and migration of pancreatic cancer.Results:Immunohistochemical staining showed that 60 (98.4%) of IKBKE staining were weakly positive, positive, and strongly positive in pancreatic cancer tissues, which were significantly higher than normal pancreatic tissues(76.9% cases were weakly positive and the rest were negative), and the differences were statistically significant ( P<0.05). All cases of NF-κB exhibited weakly positive expression and above in pancreatic cancer tissues, which was markedly higher than normal tissues (30.8% cases were weak positive and the rest were negative staining), statistically significant ( P<0.05). Survival analysis showed that patients with high level of IKBKE showed a shorter overall survival ( P<0.05). CCK-8, plate cloning and scratch assays showed that the proliferation and migration of were significantly decreased in IKBKE knocking down group ( P<0.05). Conclusions:IKBKE and NF-κB are highly expressed in pancreatic cancer, and IKBKE is correlated with NF-κB in pancreatic cancer. Blocking of IKBKE could distinctly inhibit the proliferation and migration of pancreatic cancer.

Objective:To analyze the factors influencing dysphagia after an injury to the cervical spinal cord (CPCI) to provide a basis for clinical screening and intervention.Methods:A total of 110 CPCI patients with dysphagia were divided into a severe dysphagia group ( n=19), a mild dysphagia group ( n=35), and a control group ( n=56) according to their functional oral intake scale scores. Data on gender, age, level of injury, degree of damage, duration of injury, causes of injury, surgical mode, tracheotomy status, occurrence of pneumonia and pharynx swelling were collected. Univariate and multivariate logistic regressions were evaluated to identify factors affecting swallowing. Results:The regressions highlighted age, the severity of the spinal cord injury, tracheotomy status, and the occurrence of pneumonia and pharyngeal swelling during hospitalization as the best predictors of swallowing difficulties. Multifactoral logistic regression analysis revealed that undergoing tracheotomy and catching pneumonia during hospitalization were major risk factors for severe dysphagia.Conclusions:Tracheotomy and pneumonia during hospitalization are useful predictors of severe dysphagia after a cervical spinal cord injury.

Nicotinamide mononucleotide (NMN) is an important precursor in conversing nicotinamide adenine dinucleotide (NAD +) in the body. By elevating NAD + level in the body, NMN enhances the hydrogen transfer function of NAD + in biological processes, promotes the synthesis of proteins and polysaccharides, improves substance transportation and regulatory efficiency, and enhances metabolic functions. Specifically, in central nervous system disease, NMN exerts neuroprotective effect through antioxidation, anti-inflammation, mitochondrial protection, and prevention of neuronal and axonal degeneration. This review focuses on the therapeutic role of NMN in common central nervous system diseases and their neuroprotective mechanisms, so as to further understand the role of NMN in central nervous system diseases, and provide references for predicting therapeutic targets and screening therapeutic drugs for central nervous system diseases.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
