A comparative study of different surgical method for stage ⅠA non-small cell lung cancer / 局解手术学杂志

Objective To compare the clinical efficacies of video-assisted thoracoscopic segmentectomy versus lobectomy for early-stage non-small cell lung cancer.Methods The clinical data of 234 patients with stage ⅠA non-small cell lung cancer and undergoing different surgical methods under video-assisted thoracoscopy admitted to Chongqing Dianjiang General Hospital were retrospectively analyzed,and the patients were divided into the lung segment group and the lung lobe group according to their surgical methods.The clinical characteristics of the patients in the two groups were balanced by a 1-to-1 ratio matching through the propensity score matching method,and each group finally included 63 cases.The perioperative indicators containing operation time,intraoperative blood loss,postoperative thoracic drainage tube indwelling time,thoracic drainage volumes 24 hours and 48 hours after operation and postoperative hospital stay were compared of patients between the two groups.The incidence of postoperative complications such as air leakage>6 days,pulmonary infection,atelectasis,hemoptysis,and hoarseness in the two groups was collected.Results There was no significant difference in the operation time,intraoperative blood loss,thoracic drainage volumes 24 hours and 48 hours after operation,postoperative thoracic drainage tube indwelling time or incidence of postoperative complications of patients between the two groups(P>0.05).The postoperative hospital stay of patients in the lung segment group was shorter than that in the lung lobe group,with statistically significant difference(P=0.003).Conclusion For patients with stage ⅠA non-small cell lung cancer,video-assisted thoracoscopic segmentectomy has similar perioperative efficacy to lobectomy,while segmentectomy has a more significant advantage in shortening the hospital stay.

Establishment and evaluation of in vitro galectin-3 inhibitor screening model / 药学学报

Galectin-3 (Gal-3) belongs to the galectin family and is specific in binding β-galactoside. Through its C-terminal domain, Gal-3 binds to the galactoside group of the glycosylated insulin receptor (IR) and inhibits IR signaling pathway, which leads to the insulin resistance. Thus, Gal-3 is a potential therapeutic target for the treatment of insulin resistance and type 2 diabetes. Here we report a simple Gal-3 screening model based on the property that Gal-3 binds to the galactoside. We expressed and purified human Gal-3 in Escherichia coli (E.coli), and labeled it with fluorescein isothiocyanate (FITC) in vitro. After incubating FITC labeled Gal-3 (Gal-3-FITC) with PANC-1 cells, which express glycosylated membrane protein, PANC-1 cells started to show green fluorescent signal due to the Gal-3-FITC binding to the glycosylated membrane protein. Gal-3 inhibitor disrupts the binding of Gal-3-FITC and PANC1 cells, subsequently leads to the decrease of the fluorescent signal in PANC-1 cells. We can evaluate the inhibitory efficiency of Gal-3 inhibitors through measurement of the fluorescent signal. Further studies show this model is simple, stable, and repeatable with a Z' factor between 0.7 and 0.85. In sum, we have successfully established an in vitro high-throughput screening model for Gal-3 inhibitors.

Comparative study on the methods to determine disintegration time of oral soluble films / 药学学报

Disintegration time is a key parameter that affects the palatability and compliance of oral soluble films. At present, there is no standard method to determine the disintegration time of oral soluble films. In this study, we compared the six methods (pharmacopoeial disintegration method, petri dish method, sponge surface method, slide frame and ball method, partially immersed into liquid (without weight attached) and partially immersed into liquid (with weight attached)) to determine the in vitro disintegration time of oral soluble films with different thickness, and evaluated the correlation with the in vivo disintegration time. The results showed that the repeatability and correlation of pharmacopoeial disintegration method and the partially immersed into liquid method (with weight attached) were excellent, with the endpoint of disintegration testing easy to determine. Partially immersed into liquid method (with weight attached), properly simulating the physiological condition in oral cavity, showed strong operability, good repeatability and in vitro-in vivo correlation, and was suitable for in vitro disintegration evaluation of oral soluble film dosage form. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

The clinical analysis of septic shock caused by lymphocyst infection after lymph node dissection in 13 diabetic patients / 中华急诊医学杂志

Objective:To improve the rate of successful rescue through analyzing the clinical features and treating processes of septic shock caused by lymphocyst infection after lymph node dissection in diabetic patients.Methods:A total of 462 cases of diabetic patients with bladder, prostate, renal cancers, cervical, endometrial and ovarian were retrospectively analyzed, all of whom underwent standard surgical treatments including pelvic lymph node dissection, hospitalized in department of urology surgery and gynecology of Sun Yat-sen Memorial Hospital from Jan 2015 to Jan 2020. Lymphocytes were confirmed in 148 cases, of which 89 cases were complicated by infection, and 13 cases developed septic shock. Patients with lymphocyst infection were divided into shock and non-shock groups, and age, sex, duration of diabetes, BMI, glycosylated hemoglobin at admission, number of lymph nodes surgically removed, retention time of drainage tube after operation, maximum diameter of lymphocyst and time between infection and previous chemotherapy were compared. The initial symptoms, blood routine in the first time after the onset of the infection, the time from onset to drainage puncture and catheterization and the final outcomes were analyzed in 13 patients with septic shock. The results of pathogen culture and drug sensitivity of infected lymphocyst fluid were also analyzed.Results:Categorical variable test showed that: in diabetic patients with lymphocyst infection, there were significant differences in glycosylated hemoglobin ( P=0.018) , adjuvant chemotherapy ( P=0.014) and lymphocyst size ( P<0.001) between shock group and non-shock group. Among the 13 cases of septic shock, 11 caseshad mild to moderate fever or abdominal pain. The total leukocyte count of all cases in the first hemogram were less than 20×10 9/L. The average time from onset to drainage was 33 hours. Among the 13 patients, 5 developed MODS and 1 died. There were 2 patients whose conditions were complex with frequent fluctuations. In the 12 patients who recovered from septic shock, only 1 underwent a residual lymphocyst pretreatment, 4 had recurrent cyst infection for 1-2 times, 2 had septic shock again, and 1 died. Gram negative bacteria were the most common pathogens, and the main was Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Piperacillin / tazobactam, carbapenems and tigecycline were commonly sensitive, while the drug resistance rates of ceftazidime, ceftriaxone and levofloxacin were more than 50%. Conclusions:Poor glycemic control, adjuvant chemotherapy and big lymphocyst size(d≥5 cm) are the high risk factors of septic shock. Most of shock patients' initial symptoms and total white blood cell count have no warning significance, leading to longer time from infection to drainage, and delayed treatment. Early diagnosis, timely drainage and active anti-infection treatment are the key to a successful treatment. The possibility of connection between lymphocyst and surrounding organ should be considered when the treatment effect is not good. After septic shock of postoperative lymphocyst infection in patients with diabetes, the larger esidual lymphocyst should be intervened actively to avoid serious infection again.

Research progress on the regulatory mechanism of estrogen in periodontal ligament cells repair and the reconstruction of periodontal tissue / 口腔疾病防治

@#Periodontium regeneration and repair is a controversial and difficult point in the treatment of periodontosis. The proliferation, differentiation, migration and adhesion of periodontal ligament cells and the dynamic relationship between periodontal ligament cells and their extracellular matrix proteins are the basis of periodontium morphological reconstruction, functional maintenance and tissue repair. This article reviews the mechanism of estrogen-regulated periodontal membrane fine repair and periodontal tissue reconstruction to provide the basis for follow-up research on the treatment of periodontitis and the promotion of periodontal tissue repair and reconstruction by exogenous estrogen-mediated periodontal membranes. Under the regulation of certain concentrations of estrogen, the proliferation and differentiation ability of periodontal ligament stem cells (PDLSCs) and bone mesenchymal stem cells (BMSCs) to other periodontal ligament cells were enhanced. At the same time, PDLSCs, BMSCs, human periodontal ligament fibroblasts (HPLFSs), osteoblasts and cementoblasts synthesized and secreted collagen I (COLI), osteopontin (OPN), bone sialoprotein (BSP) and osteocalcin (OCN) into the extracellular matrix. They interact with fibronectin (FN) and cementum attachment protein (CAP) in the extracellular matrix to form a variety of chain complexes and regulate each other, thus promoting the growth, migration, adhesion and fibrosis of periodontal ligament cells, repairing the collagen fiber skeleton of the periodontal ligament and adhering the two ends to the new cementum and the inherent alveolar bone.

Objective:To investigate the experience and results of the modified lateral prostate capsule sparing robot-assisted radical cystectomy-orthotopic ileal neobladder (LPCS-RARC-OIN).Methods:From December 2018 to November 2020, 19 patients received LPCS-RARC-OIN by a single surgeon in Sun Yat-sen Memorial Hospital, Sun Yat-sen University. LPCS-RARC-OIN was performed on male patients with high-risk non-muscle-invasive bladder cancer or muscle-invasive bladder cancer cT 2N 0M 0 without tumour in the bladder neck or urethra, and prostate cancer was ruled out by MRI and serum PSA<2.5ng/ml. The average age was 57.6 years, the average IIEF-5 score was 20.4. Separating the prostatic adenoma and the lateral prostate capsule from the base to the apex of the prostate, and retaining the lateral prostate surgical capsule or lateral prostate capsule about 1-2mm thickness. Patients were followed up and urinary function, sexual function and oncological outcomes were recorded. Results:All 19 operations were finished successfully. The average operation time was 279.9 (225-345) min and average estimated blood loss was 88.9 (30-200) ml. The average postoperative hospital stays was 15.8 (9 -23) days. The average lymph node yields was 23.3 (11-42). All surgical margins were negative and no incidental prostate cancer was found. 2 weeks, 1 month, 3 months and 6 months after catheter removal, the daytime and nighttime continence were 42.1% (8/19)and 36.8% (7/19), 63.2% (12/19)and 63.2% (12/19), 78.9% (15/19) and 73.7% (14/19), 94.7% (18/19) and 89.5% (17/19), respectively. 3 months and 6 months after operation, the average IIEF-5 score was 7.2 and 10.1 points respectively. The average follow-up was 10.6 months (5.4-26.1 months)and no recurrence or distant metastasis was found in this study.Conclusions:LPCS-RARC-OIN could improve the urinary and sexual function in selected patients. However, the long-term follow up is needed for functional and oncological outcomes.

Location, incidence and clinical implications of the root canal isthmus / 口腔疾病防治

@#Root canal isthmus(RCI) is defined as a narrow, ribbon-shaped communication between two root canals that contains pulp or tissue derived from pulp. Any root that contains two or more root canals has the potential to contain an isthmus. The incidence of RCI from different tooth positions varies, with the highest RCI incidences usually found in the mesial root of the mandibular first molar and the mesiobuccal root of the maxillary first molar. The presence of RCI increases the difficulty of root canal therapy and introduces uncertainty regarding the prognosis for dental treatment. It is recommended to use CBCT and dental microscopy to identify teeth with suspected RCI in clinical practice. At the same time, for treatment of teeth with RCI, appropriate instruments should be selected, and enhanced root canal irrigation assisted by ultrasound should be considered to improve the success rate of root canal treatment and endodontic root-end surgery. The current technology still has some limitations regarding the cleaning and filling of RCI and additional research and development. Improvement of the corresponding technology and equipment is a current research hotspot and a future research direction.

The update interpretation of 2020 EAU bladder cancer guideline (Part Ⅰ) ——progress of muscle-invasive and metastatic bladder cancer / 中华泌尿外科杂志

The 2020 version of the European Association of Urology (EAU) guideline has updated the recommendations for the diagnosis and treatment of muscle-invasive bladder cancer and metastatic bladder cancer. The main changes include: ① Pioglitazone use was significantly associated with increased risk of bladder cancer, so pioglitazone should not be prescribed for patients with bladder cancer or a history of bladder cancer. ②Progress involved molecular classification and molecular markers was made but could not be used in routine clinical practice at present. ③ Describes in detail of proper case and technical selection about pelvic organ-sparing radical cystectomy in female patients. ④Low molecular weight haparin usage for 4 weeks can reduce the incidence of postoperative venous thromboembolism. ⑤ PD-L1 positive patients with metastatic bladder cancer ineligible for cisplatin can use pembrolizumab or atezolizumab for first-line immunotherapy.

Early precise diagnosis, multidisciplinary comprehensive treatment, standardized follow-up with rehabilitation / 中华泌尿外科杂志

Bladder cancer is prone to recurrence and metastasis, and surgical treatment alone is often difficult to achieve the goal of clinical cure. While great progress has been made in the diagnosis and treatment of bladder cancer in our country, there are also problems of insufficient standardization of treatment, limited treatment options and insufficient postoperative follow-up, and the level of diagnosis and treatment varies greatly among different institutions. We should vigorously promote the full course treatment and personalized fine management with "early accurate diagnosis, multi-disciplinary comprehensive treatment and standardized follow-up rehabilitation" as the core content. We should pay attention to both comprehensive treatment of the disease and the psychological needs of patients, and improve the quality of life of patients, to achieve the goal of "curing the disease, curing the body, and healing the mind" . In terms of specific implementation paths, we should use the professional case management model, pay attention to multi-disciplinary collaboration, and make full use of the database and Internet platform to manage the entire process.

Reconstruction of Vehicle-pedestrian Collision Road Traffic Accidents Based on PC-Crash Software / 法医学杂志

Objective To discuss the application value of vehicle-pedestrian collision road traffic accidents reconstruction based on PC-Crash software in forensic identification. Methods A case of vehicle-pedestrian collision was chosen based on a tachograph, then PC-Crash software was applied to construct a vehicle-pedestrian collision model, and reconstruct the vehicle-pedestrian collision road traffic accident. Finally, the process of vehicle-pedestrian collision was reproduced. Results In accident reconstruction, when the car speed was lower than 50km/h, the landing point of the pedestrian after collision was in the front of the car. When the car speed was higher than 50 km/h, after collision, the pedestrian flipped towards the car roof and landed behind the car. With the increase of vehicle speed, throwing distance of the pedestrian increased continuously. When the vehicle collision speed reached 60 km/h, the experimental results in this case were basically consistent with the actual situation of the case. Head acceleration of the pedestrian was at the maximum （1 655.70 m/s2） at 0.080 s. Chest acceleration of the pedestrian increased from 597.63 m/s2 to the peak 675.52 m/s2 at 0.055-0.060 s. Tibia acceleration of the pedestrian increased from 759.26 m/s2 to the first peak 1 367.06 m/s2, then reached the maximum speed （1 718.19 m/s2） at 1.225 s. Conclusion The process of vehicle-pedestrian collision road traffic accidents can be reconstructed based on PC-Crash software under a situation of limited conditions, and can further clarify the speed of the vehicle, the location and degree of human body injury as well as the mechanism of damage of the pedestrian in the accident. Therefore, PC-Crash software has a certain practical value in forensic identification of road traffic accidents.

Impact of 1 25(OH) 2 D 3 on TG content in liver of rats with type 2 diabetes

Abstract Purpose: To evaluate the effects of 1,25 dihydroxy vitamin D3 (1,25(OH)2D3) on the content of triglyceride (TG), as well as on the gene and protein expressions of adiponectin receptor 2 (AdipoR2), p38 mitogen-activated protein kinase (P38MAPK), and lipoprotein lipase (LPL) in the liver of rats with type 2 diabetes mellitus (T2DM) so as to provide theoretical basis for exploring the mechanism by which 1,25(OH)2D3 regulates TG. Methods: Wistar rats were divided into four groups (n=25), with different treatments and detected the gene and protein expressions of AdipoR2, p38MAPK, and LPL in the liver tissue by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. Meanwhile, the content of TG in the liver tissue was detected by the Enzyme-linked immunosorbent assay. Results: The expression of AdipoR2, p38MAPK, LPL gene and protein in the liver of VitD intervention group was significantly higher than that in T2DM group (P <0.05), while the TG content was significantly lower than that in T2DM group (P <0.05). Conclusion: 1,25(OH)2D3 can decrease the content of TG in the liver, and its mechanism may be achieved by upregulating the expressions of AdipoR2, p38MAPK, and LPL in the liver.

Effects of gastrodin against SH-SY5Y cell autophagy induced by methamphetamine and underlying mechanisms / 中国药理学通报

Aim To investigate the effects of gastrodin on SH-SY5Y cell autophagy induced by methamphet-amine (METH) and the underlying mechanisms. Methods SY5Y cells were treated by METH with the concentration of 0.5,1.0,1.5,2.0,2.5,3.0 mmol·L-1for 24 h. The morphological changes were ob-served by microscopy,the expression of LC3-Ⅱ,Bec-lin-1,Akt,p-Akt,mTOR and p-mTOR were detected by Western blot. Gastrodin was added to the medium 1 h before METH treatment. Results The SY 5 Y cells were morphologically featured by shrinkage and den-drite disruption after exposed to METH(0~3 mmol· L-1),and autophagic vacuoles occurred in cytoplasm. The expression of LC3-Ⅱ increased over METH dose. Confocal results showed that LC3-Ⅱsignificantly in-creased in METH group as compared with control, while decreased in METH+ Gastrodin group. The ex-pression levels of LC3-Ⅱand Beclin-1 significantly in-creased (P<0.01) in METH group, p-mTOR and p-Akt decreased, and mTOR and Akt showed no signifi-cant difference as compared with control. However, the gastrodin could decrease the expression of LC3-Ⅱand Beclin-1 and increase the expression of mTOR,p-mTOR,Akt and p-Akt as compared with METH-trea-ted groups. Conclusions METH can induce SY5Y cells autophagy. The protective effect of gastrodin a-gainst METH-induced autophag may be related to gast-rodin regulation mTOR and Akt signaling pathway.
