Objective To analyze the detection ability of survival motor neuron(SMN)gene deletion of exons in clinical laboratories in Shanghai using external quality assessment(EQA).Methods Genomic DNA from the cell lines containing different SMN exon copy numbers were selected as EQA samples.The EQA sample panel,which consisted of 5 samples,was randomly selected twice and distributed to participating laboratories in Shanghai in 2023.The seresults were required to be conducted and uploaded within the specified time.Based on the reported results,statistical analysis was performed and the detection ability was evaluated.Results In the two EQA,laboratory that submitted all correct results for SMN1 accounted for 100%(38/38)and 97.22%(35/36),respectively.The overall coincidence rates were 96.92%(315/325)and 98.18%(324/330)for copy number detection of SMN1 exon 7 and 8,100%(65/65)and 96.56%(43/45)for copy number detection of SMN2 exon 7 and 8.The reported error results included case of result judgment error and 4 cases of copy number detection errors.Conclusion Screening genomic DNA from the cell lines containing different SMN exon copy numbers can effectively simulate the clinical samples,which can be applied to EQA material for deletion of exons in the SMN gene.The reported results show that the overall compliance rate of SMN deletion of exons in clinical laboratories in Shanghai is relatively high,but the testing capabilities of some laboratories still need to be improved.

ObjectiveTo investigate the effect of Mashao Pingchuan decoction （MSPC） on lipopolysaccharides （LPS）-induced autophagy in human bronchial airway epithelial cells （16HBE） via the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. Method16HBE cells were selected for the study， and cell counting kit-8 （CCK-8） was used to detect the activity of of LPS-induced 16HBE cells and the effect of MSPC-containing serum on the cells. Suitable LPS-induced 16HBE cells were screened by the CCK-8 method， and the content of tumor necrosis factor-α （TNF-α） was measured to identify the established model. And MSPC-containing serum was prepared. The cells were divided into normal group， LPS group， LPS+MSPC group， LY294002+LPS group and LY294002+LPS+MSPC group. Transmission electron microscopy was performed to observe the changes in autophagic vesicles and ultrastructure of the cells. Western blot was performed to detect the protein expressions of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， mTOR， phosphorylated mTOR （p-mTOR） and microtubule-associated protein 1 light chain 3B （LC3B）， and enzyme-linked immunosorbent assay （ELISA） was used to detect the expressions of inflammatory factors interleukin-5 （IL-5）， IL-6， TNF-α and IL-10 in the five groups. ResultLPS inhibited the 16HBE cells in a dose-dependent manner. Compared with the normal group， the LPS group （150 mg·L^-1 of LPS） increased the expression of pro-inflammatory factor TNF-α after 24 h of treatment （P<0.05） and facilitated the autophagosome formation， and MSPC-containing serum exerted a concentration-dependent promotion effect on the 16HBE cells， inhibited the autophagy to a certain degree and enhanced the cell status. Western blot revealed that the protein expressions of p-PI3K， p-Akt and p-mTOR in the model group were lower （P<0.05） and the protein expression of LC3B was higher （P<0.01） than those in the normal group. Compared with the conditions in the LPS group， the protein expressions of p-PI3K， p-Akt and p-mTOR in the LPS+MSPC group were elevated （P<0.05） and that of LC3B was reduced （P<0.05）. Compared with the LPS+LY294002 group， the LY294002+LPS+MSCP group had up-regulated protein expressions of p-PI3K， p-Akt and p-mTOR （P<0.05） and down-regulated protein expression of LC3B （P<0.05）. ELISA showed that the LPS group had higher levels of IL-5， IL-6， TNF-α and IL-10 than the normal group， while the levels of TNF-α， IL-6 and IL-8 were decreased （P<0.01） and the level of IL-10 was increased （P<0.01） after treatment with MSCP. ConclusionMSCP may lower the LPS-induced autophagy in 16HBE cells and improve the inflammatory response through activating the PI3K/Akt/mTOR signaling pathway.

Objective:To investigate the effect of arthroscopically-assisted open reduction and internal fixation of intra-articular distal radius fracture.Methods:A retrospective cohort study was made on clinical data of 44 patients with distal radial intraarticular fracture admitted to Jing′an District Central Hospital, Fudan University between June 2017 and August 2020. There were 13 males and 31 females, at age of 35-85years [(62.5±12.9)years]. According to AO/OTA fracture classification system, there were 7 patients with type B and 37 with type C. Open reduction and internal fixation with volar plate was used in all patients, among which 22 were operated on using arthroscopy assistance (arthroscopy group) and 22 were operated on with traditional intraoperative fluoroscopy (fluoroscopy group). The operation time in both groups and triangular fibrocartilage complex (TFCC) injury and fracture displacement in arthroscopy group were recorded. Patient-rated wrist evaluation (PRWE) score, disabilities of the arm, shoulder and hand (DASH) questionnaire and range of wrist motion were compared between the two groups at 12 months after operation. The incidence of complications was observed.Results:All patients were followed up for 12-15 months [(13.3±1.1)months]. The operation time in arthroscopy group was (104.0±40.5)minutes, longer than (71.3±32.1)minutes in fluoroscopy group ( P<0.05). In arthroscopy group, 14 patients (64%) with TFCC injury were diagnosed intraoperatively, with the fracture displacement gap and step for 0.8 (0.3, 0.8)mm and 1.0 (0.3, 1.5)mm under arthroscopic vision, which were reduced to 0.3 (0.0, 0.5)mm and 0.5 (0.0, 0.5)mm after arthroscopically-assisted reduction (all P<0.05). The PRWE score in arthroscopy group was (9.8±4.9)points at 12 months after operation, lower than (13.4±5.8)points in fluoroscopy group ( P<0.05). The DASH questionnaire in arthroscopy group was (9.0±5.0)points at 12 months after operation, lower than (13.0±6.1)points in fluoroscopy group ( P<0.05). The dorsal extension and posterior rotation of the wrist in arthroscopy group were (73.8±8.9)° and (82.5±8.0)°, higher than (65.8±14.2)° and (76.3±10.4)° in fluoroscopy group (all P<0.05). There were no postoperative complications such as loosened or broken screws, vascular nerve damage, incision infection or traumatic arthritis in both groups. Conclusion:Arthroscopic-assisted open reduction and internal fixation of intra-articular distal radius fracture can increase the accuracy of joint surface reduction, improve postoperative wrist function and confirm the diagnosis of TFCC injury during operation.

Background::The preferred therapeutic regimen for Toxoplasma encephalitis (TE) is a combination of pyrimethamine and sulfadiazine, and trimethoprim-sulfamethoxazole (TMP-SMX) plus azithromycin is the widespread alternative therapeutic regimen. The synergistic sulfonamides tablet contains TMP, sulfadiazine, and SMX and hypothetically could be used for TE treatment. This study aimed to compare the efficacy and safety of synergistic sulfonamides plus clindamycin (regimen B) with TMP-SMX plus azithromycin (regimen A) for the treatment of human immunodeficiency virus (HIV) associated TE.Methods::This was an open-labeled, multi-center randomized controlled trial recruited from 11 centers. Each recruited patient was randomly assigned to receive regimen A or regimen B for at least 6 weeks. The overall response was evaluated by assessment of the clinical response of TE-associated clinical features and the radiological response of TE-associated radiological findings. The overall response rate, clinical response rate, radiological response rate, and adverse events were assessed at 2, 6, and 12 weeks. Death events were compared between the two regimens at 6, 12, and 24 weeks.Results::A total of 91 acquired immunodeficiency syndrome (AIDS)/TE patients were included in the final analysis (44 in regimen A vs. 47 in regimen B). The overall response rate, which refers to the combined clinical and radiological response, was 18.2% (8/44) for regimen A and 21.3 % (10/47) for regimen B at week 6. The results of clinical response showed that, in comparison with regimen A, regimen B may perform better with regards to its effect on the relief of clinical manifestations (50.0% [22/44] vs. 70.2% [33/47], P = 0.049). However, no significant differences in radiological response, mortality events, and adverse events were found between the two regimens at week 6. Conclusions::Synergistic sulfonamides plus clindamycin, as a novel treatment regimen, showed no significantly different efficacy and comparable safety in comparison with the TMP-SMX plus azithromycin regimen. In addition, the regimen containing synergistic sulfonamides may exhibit advantages in terms of clinical symptom alleviation.Trial Registration::ChiCTR.org.cn, ChiCTR1900021195.

Objective:To investigate clinicians' compliance with the 2018 Surviving Sepsis Campaign (SSC) update "1-hour sepsis Bundle therapy" (1-hour Bundle) when treating patients with Sepsis 3 in the intensive care unit (ICU), and to analyze its impact on patient outcomes.Methods:A multicenter, prospective observational cohort study was conducted. A total of 153 ICU patients in Ziyang First People's Hospital, Ziyang People's Hospital and Yanjiang District People's Hospital who were diagnosed of sepsis by the definition and diagnostic criteria of Sepsis 3 from January 2019 to December 2020 were selected. Among them, 95 patients who had completed 1-hour Bundle were divided into the Bundle compliance group. 58 patients who did not complete the Bundle within 1 hours were classified as the Bundle non-compliance group. The distribution of pathogenic bacteria and infected sites, 1-hour Bundle compliance and 28-day survival in the 3 hospitals were analyzed. Univariate analysis was used to analyze the risk factors affecting the prognostic between the two groups of sepsis patients. Cox regression model was used to draw a 28-day survival curve to evaluate the survival of the patients in the two groups.Results:Among 153 sepsis patients in 3 hospitals, the detection rate of pathogenic bacteria was 61.44% (94/153), and Gram-negative bacteria accounted for 79.79% (75/94). The top 3 infection sites were respiratory system, gastrointestinal tract and urinary system, accounted for 32.0%, 28.1% and 18.3%, respectively. In the 3 hospitals, 62.09% (95/153) of patients fully implemented the 1-hour Bundle. The poorly implemented indicators in the 1-hour Bundle were 1-hour blood microbial culture [77.78% (119/153)] and 1-hour antimicrobial application [79.74% (122/153)]. There was no significant difference in the baseline indicators between Bundle compliance and non-compliance groups. Univariate analysis showed that the main prognostic indicators: 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group [80.00% (76/95) vs. 62.06% (36/58), χ2= 6.447, P = 0.014]. Secondary evaluation indicators: mean arterial pressure (MAP) at 6 hours and 24 hours in the Bundle compliance group were significantly higher than those in the Bundle non-compliance group [mmHg (1 mmHg = 0.133 kPa): 78.22±11.25 vs. 69.86±14.04, 79.78±11.45 vs. 75.35±12.90]. However, the median length of in hospital stay in the Bundle compliance group was significantly longer than that in the Bundle non-compliance group [days: 13 (17) vs. 6 (11)], with statistically significant differences (all P < 0.05). Bivariate Logistic regression analysis showed that 6 hours and 24 hours MAP were risk factors affecting the prognosis of patients with sepsis [odds ratio ( OR), 95% confidence interval (95% CI): 1.064 (0.994-1.102), 1.032 (1.003-1.063), both P < 0.05]. Conclusions:The 1-hour Bundle compliance rate of ICU patients with sepsis in 3 hospitals of Ziyang City was 62.09%, and the compliance is still to be improved, especially for the 2 aspects of empirical antimicrobial use and microbial culture retention before antimicrobial use. The 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group, suggesting that the 1-hour Bundle regimen can improve the prognosis of patients with sepsis.

Objective:To evaluate the clinical value of the holographic image and navigation in robotic assisted laparoscopic radical prostatectomy (RARP) .Methods:From Sept. 2020 to Dec. 2020, 5 patients diagnosed with prostate cancer in Beijing United Family Hospital were included in this study. The mean age was 57 years(38-69 years). Before the operation, the engineers established the holographic image based on the enhanced MRI images. The holographic images were used in pre-surgery planning. During the operation, the navigation was achieved by real time fusing holographic images with the robotic surgery endoscopic views.

Objective To explore the effects of triclosan (TCS) on the immune function of mice. Methods Forty male and female Kunming mice (25±2 g) were selected. The animals were divided into 5 groups according to body weight ratio, including a blank control (saline solution) group, dimethyl sulfoxide (DMSO) group, and three triclosan solution groups (59.375 mg/kg, 118.75 mg/kg, and 237.5 mg/kg, respectively). There were 8 mice in each group, half male and half female. Animals were treated with TCS by intragastric administration once a day for two weeks. Upon the completion of the treatment, animals were sacrificed, the spleen, thymus and other tissues were collected, and the ratios of their weight to body weigh were calculated. The peripheral blood was taken by eye-ball removal method, and the half hemolysis value was determined. Results Compared with the positive control group, the spleen index of male mice in the medium dose group and high dose group increased significantly (P < 0.05), and the spleen index of female mice in the high dose group showed significant difference (P < 0.05). Compared with the positive control group, the thymus index of male high dose group was significantly different (P < 0.05). The thymus indexes of female high, medium, and low dose groups all were significantly different compared to the control group (P < 0.05). HC50 results showed that the HC50 of both male and female mice decreased (P < 0.05). Conclusion High concentration of triclosan can inhibit the immune function of Kunming mice.
