Abstract
OBJECTIVE To systematically evaluate obesity on the outcome of rotator cuff repair. METHODS Literatures on the relationship between obesity and outcomes after rotator cuff repair were searched from PubMed, Embase, Cochrane Library, Web of Science, China biology medicine(CBM), CNKI, Wanfang and VIP databases from building database to August 1, 2022, and were screened independently by two authors according to inclusion and exclusion criteria. Endnote X9 and Excel 2019 were used for literature extraction, management and data entry, and Newcastle-Ottawa Scale (NOS) was used to evaluate quality of the included literatures. STATA 16.0 and RevMan 5.4 softwares were used to evaluate postoperative retear rate, reoperation rate, complication rate, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), operative time and external rotation angle of shoulder joint pain were analyzed. RESULTS Totally 13 literatures were included, including 6 retrospective studies, 5 case-control studies, 1 prospective cohort study, and 1 abstract of a study for which the full text was not available, with 85 503 patients (31 973 in obese group and 53 530 in non-obese group). Meta-analysis showed there were statistical differences between two groups in retear rate [OR=2.58, 95%CI(1.23, 5.41), P=0.01], reoperation rate[OR=1.31, 95%CI(1.21, 1.42), P<0.00], complication rate [OR=1.57, 95%CI(1.31, 1.87), P=0.00], ASES score[MD=-3.59, 95%CI(-5.45, -1.74), P=0.00], and VAS[MD=0.24, 95%CI(0.00, 0.49), P=0.05]. While there were no differences between two groups in operative time[MD=6.03, 95%CI(-7.63, 19.69), P=0.39], external rotation angle of shoulder joint[MD=-1.79, 95%CI(-5.30, 1.71), P=0.32]. CONCLUSION Obesity is associated with higher rates of retear, resurgery, complications, poorer shoulder function and pain after rotator cuff repair.

Abstract
The shoulder joint is the most flexible joint in the body with the largest range of motion, and the movement pattern is more complex. Accurate capture of three-dimensional motion data of the shoulder joint is crucial for biomechanical evaluation. Optical motion capture systems offer a non-invasive and radiation-free method to capture shoulder joint motion data during complex movements, enabling further biomechanical analysis of the shoulder joint. This review provides a comprehensive overview of optical motion capture technology in the context of shoulder joint movement, including measurement principles, data processing methods to reduce artifacts from skin and soft tissues, factors influencing measurement results, and applications in shoulder joint disorders.

Abstract
Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred. For the older patients(≥35 years old) with degeneration and wear of glenoid labrum, biceps tenodesis is more preferable, and interference screw fixation technique is recommended. As for patients with failed SLAP repair, biceps tenodesis can achieve a high success rate as a revision surgery. By review of the relevant literature in recent years, this paper summarizes the adaptation of different surgical methods of arthroscopic treatment of SLAP injury, intraoperative anchoring techniques, fixation methods and other improved surgical techniques.

Abstract
The surgical treatment of massive rotator cuff tears is a clinical challenge for orthopaedic surgeons. Moreover, tendon retraction, adhesions and fatty infiltration after rotator cuff tear will further increase the difficulty of surgical repair. Therefore, it has become a hotspot and difficulty to repair massive rotator cuff tears with a better way in current research. In recent years, with the continuous development of arthroscopic techniques, shoulder arthroscopic surgery has become the gold standard for the treatment of massive rotator cuff tears, but the adaptations, effects and combined application of different surgical methods are still controversial. The author believes that arthroscopic debridement of shoulder joint and acromioplasty or tuberoplasty could relieve shoulder pain in the short-term for elderly patients with lower functional requirements;long biceps tenotomy or tenodesis is effective for patients with biceps long head tendon injury; complete repair is still the first line treatment for massive rotator cuff tears, but partial repair is possible for massive rotator cuff tears that could not be completely repaired;patch augmentation technology could bring good results for young patients with high functional requirements;for patients with limited internal and external rotation of the shoulder joint and high functional requirements, tendon transfers surgery is recommended;superior capsular reconstruction is more advantageous for young patients with no obvious glenohumeral arthritis, better deltoid muscle strength and higher functional requirements. In addition, subacromial spacer implantation has become a current research hotspot due to its advantages of small trauma, low cost and relative safety, and its long-term effect still needs to be further confirmed.

Abstract
PURPOSE Infection with carbapenem-resistant Klebsiella pneumoniae (CRKP) is a great challenge. Central nervous system (CNS) infection caused by CRKP is rarely reported, and effective treatment is limited. Thus, this study aimed to assess intrathecal (IT) or intraventricular (IVT) injection of tigecycline for clearing infection with CRKP in CNS. PATIENTS AND METHODS Two patients who had intracranial infection with CRKP after craniotomy were treated in our institution and analyzed retrospectively, summarizing their therapeutic schedules. RESULTS They all had a fever with the positive results of cerebrospinal fluid (CSF) test, and CSF culture showed positive for CPKP, which was sensitive only to tigecycline. In addition, the MIC of polymyxin B was not tested due to the limited laboratory conditions. After IT or IVT injection of tigecycline treatment, the temperature of the patients became normal in 3 days, with normal levels of white blood cells, protein, glucose and chlorine concentrations in the CSF. Crucially, twice CSF cultures also became negative with no clinical symptoms of intracranial infection after IT or IVT injection of tigecycline treatment. Moreover, there were no adverse drug reactions observed. CONCLUSION IT or IVT injection of tigecycline may be a bright choice to control intracranial infection with CRKP.

Abstract
OBJECTIVE To investigate the method and clinical effects of the treatment of recurrent shoulder dislocation with severe glenoid injury by arthroscopic subscapularis augmentation. METHODS From March 2019 to August 2020, 16 patients with recurrent dislocation of shoulder with severe glenoid injury underwent arthroscopic subscapularis augmentation, including 10 males and 6 females, aged from 18 to 50 years old with an average of (29.06±10.54) years old, 4 cases of left shoulder and 12 cases of right shoulder.Visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score and Rowe score were used to evaluate shoulder function and stability before and after operation. RESULTS All the 16 patients were followed up from 12 to 29 months, with an average of (18.75±7.26) months. VAS score decreased from 5.25±1.13 before operation to 1.37±0.65 at the final follow-up;ASES score increased from 59.44±9.93 before surgery to 90.88±4.00 at the final follow-up; Rowe score of shoulder increased from 51.56±8.89 before surgery to 92.19±7.06 at the final follow-up, and the differences were statistically significant (P<0.05). No dislocation was observed during follow-up. No clinical complications such as incision infection, vascular and nerve injury occurred in all patients after operation. CONCLUSION Arthroscopic subscapularis augmentation in the treatment of recurrent dislocation of shoulder with severe glenoid injury is satisfactory. It is an effective treatment method of recurrent dislocation of shoulder joint with severe glenoid injury, and external rotation function in patients with almost unaffected.

Abstract
Background Anastomotic leakage (AL) is one of the most serious postoperative complications. This study aimed to investigate the predictive value of preoperative body composition for AL in patients with colorectal cancer (CRC). Methods We first reviewed data from 3,681 patients who underwent radical CRC resection 2013–2021 in our hospital, and 60 patients were diagnosed with AL after surgery. We designed a nested case-control study and two controls were randomly selected for each case according to the time and position of surgery. Body composition was measured at the level of the third lumbar vertebra based on computed tomography (CT) images. The risk factors of AL were analyzed by univariate and multivariate analysis. Nomogram was built using binary regression analysis and assessed for clinical usefulness, calibration, and discrimination. Results In the multivariate analysis, gender, blood glucose, nutrition risk screening (NRS), skeletal muscle area (SMA) and visceral fat area (VFA) were independent risk factors for developing anastomotic leakage after surgery. The prognostic model had an area under the receiver operating characteristic curve of 0.848 (95% CI, 0.781–0.914). The calibration curve showed good consistency between the predicted and observed outcomes. Decision curve analysis indicated that patients with colorectal cancer can benefit from the prediction model. Conclusions The nomogram that combined with gender, blood glucose, NRS, SMA, and VFA had good predictive accuracy and reliability to AL. It may be conveniently for clinicians to predict AL preoperatively and be useful for guiding treatment decisions.

Abstract
Background Existing scoring systems have limitations in predicting the in-hospital mortality of adult sepsis patients. We aimed to develop and validate a novel risk score for predicting the in-hospital mortality of adult sepsis patients. Methods The clinical data of 1,335 adult sepsis inpatients were retrospectively analyzed. Enrolled patients were randomly divided into a modeling group and a validation group at a 3:2 ratio. The modeling group (n=801) was used to develop the risk score by univariate and multivariate logistic regression analyses. The score’s performance was validated in the validation group (n=534). We classified patients into four risk levels according to the novel risk score. Results Age, central vein catheterization, mechanical ventilation, vasopressin, Charlson comorbidity index (CCI), respiratory rate (RR), heart rate (HR), Glasgow coma scale (GCS) score, platelet (PLT), hematocrit (HCT), aspartate aminotransferase (AST), and activated partial thrombin time (APTT) were independent risk factors for in-hospital death in adult sepsis patients. Continuous variables were converted into classified variables to develop the risk score, with a total score of 39 points. Adult sepsis patients with low, lower medium, higher medium, and high risk levels had in-hospital mortality rates of 9.8%, 24.7%, 55.8%, and 83.5%, respectively. Conclusions Compared with the Acute Physiology and Chronic Health Evaluation II scoring system (APACHE II) and the Modified Early Warning Score (MEWS), the novel risk score showed good predictive performance for in-hospital mortality in adult sepsis patients.

Abstract
OBJECTIVE To investigate the early efficacy of arthroscopic autologous osteochondral grafting in the treatment of recurrent anterior shoulder dislocation. METHODS From January 2019 to January 2021, 17 patients with recurrent anterior dislocation of shoulder who underwent arthroscopic autologous osteochondral grafting were selected, including 12 males and 5 females, ranging in age from 17 to 55 years old, with a mean of (32.88±12.33) years old. Rowes rating system for Bankart repair(Rowe), Oxford Shoulder Instability Score (OSIS) and Simple Shoulder Test (SST) were compared before operation, 6 months after operation and at the latest follow-up. OSIS and SST used to evaluate shoulder function were recorded before surgery and at the latest follow-up. The shoulder mobility and intraoperative and postoperative complications were also recorded. RESULTS All 17 patients were followed up, and the duration ranged from 7 to 25 months, with a mean of (18.4±5.4) months. During the follow-up period, there was no re-dislocation, no vascular or nerve injury. Rowe score increased from 26.2±6.0 before operation to 74.4±4.0 and 82.4±3.1 after 6 months and the latest follow-up. There was significant difference in Rowe score between different time points after operation and before operation (P<0.05). The OSIS increased from 37.0±3.6 before operation to 47.4±2.6 and 52.7±2.6 after 6 months and the latest follow-up. There was significant difference in OSIS between different time points after operation and before operation (P<0.05). The SST score increased from 6.8±0.7 before operation to 9.8±0.8, 11.6±2.6 after 6 months and the latest follow-up. There was significant difference in SST score between different time points after operation and before operation (P<0.05). At the latest follow-up, the lateral external rotation and abduction external rotation activities of the patient were significantly improved compared with those before operation. CONCLUSION This study provides preliminary evidence that arthroscopic autologous osteochondral grafting can achieve satisfactory early clinical outcomes and stability in patients with recurrent anterior shoulder dislocation with glenoid fracture and defect less than <20%, which is a reliable and effective procedure.

Abstract
OBJECTIVES Accurate preoperative differentiation between squamous cell carcinoma (SCC) and non-Hodgkin's lymphoma (NHL) in the palatine tonsil is crucial because of their different treatment. This study aimed to construct and validate a contrast-enhanced CT (CECT)-based radiomics nomogram for preoperative differentiation of SCC and NHL in the palatine tonsil. METHODS This study enrolled 135 patients with a pathological diagnosis of SCC or NHL from two clinical centers, who were divided into training (n = 94; SCC = 50, NHL = 44) and external validation sets (n = 41; SCC = 22, NHL = 19). A radiomics signature was constructed from radiomics features extracted from routine CECT images and a radiomics score (Rad-score) was calculated. A clinical model was established using demographic features and CT findings. The independent clinical factors and Rad-score were combined to construct a radiomics nomogram. Performance of the clinical model, radiomics signature, and nomogram was assessed using receiver operating characteristics analysis and decision curve analysis. RESULTS Eleven features were finally selected to construct the radiomics signature. The radiomics nomogram incorporating gender, mean CECT value, and radiomics signature showed better predictive value for differentiating SCC from NHL than the clinical model for training (AUC, 0.919 vs. 0.801, p = 0.004) and validation (AUC, 0.876 vs. 0.703, p = 0.029) sets. Decision curve analysis demonstrated that the radiomics nomogram was more clinically useful than the clinical model. CONCLUSIONS A CECT-based radiomics nomogram was constructed incorporating gender, mean CECT value, and radiomics signature. This nomogram showed favorable predictive efficacy for differentiating SCC from NHL in the palatine tonsil, and might be useful for clinical decision-making. KEY POINTS • Differential diagnosis between SCC and NHL in the palatine tonsil is difficult by conventional imaging modalities. • A radiomics nomogram integrated with the radiomics signature, gender, and mean contrast-enhanced CT value facilitates differentiation of SCC from NHL with improved diagnostic efficacy.

Abstract
This study aimed to investigate whether free fatty acids (FFAs) could induce the release of neutrophil extracellular traps (NETs), as well as the mechanism of FFAs-induced NETs in acute lung injury (ALI). FFAs were used to induce NETs production. The reactive oxygen species (ROS) production was detected after FFA and NADPH oxidase inhibitor treatments. The association between FFAs-induced NETs and the activation of p38, ERK, and JNK pathways was investigated. The effect of FFAs-induced NETs on the dendritic cells (DCs) activation and T cell differentiation was investigated. FFAs could induce neutrophils to produce NETs. FFAs significantly promoted ROS production and increased the expression of ERK, p38 and JNK, and treatment of the inhibitors of NAPDH oxidase (DPI), p38 (SB202190), ERK1/2 (U0126) and JNK (SP600125) inhibited FAAs-induced NETs production. FFAs induced NETs could promote DCs activation and consequently led to the differentiation of primary CD4+ T cells into Th1 and Th17 cells and the release of IL-1β, IL-12 and TNF-α. FFAs are capable of inducing NETs via NOX, ERK, p38 and JNK pathways. FFA-induced NETs further lead to DCs activation and T cell differentiation, which can well explain the mechanism of ALI caused by FFAs.

Abstract
Background Giant cell tumors of the mobile spine invasion of the adjacent vertebrae are an ignored imaging finding. Methods Nine patients with giant cell tumors of the mobile spine with invasion of the adjacent vertebrae confirmed by pathology were enrolled. Eight patients had pure giant cell tumors (GCTs), while one patient also had an aneurysmal bone cyst. All patients underwent conventional computed tomography, three-dimensional reconstruction, and conventional magnetic resonance imaging, while seven patients also underwent post-contrast magnetic resonance imaging. Results All patients showed GCTs of the mobile spine that arose from the vertebral body and extended to the vertebral arch. The tumors showed soft-tissue attenuation with no evidence of a mineralized matrix. Pathological fracture was seen in five patients. The margin of the original tumor showed partial sclerosis in four patients and involved an adjacent vertebral body with a sclerotic rim in two patients. The tumors showed a homogeneous and similar signal intensity to the normal spinal cord on T1WI (T1-weighted image) in five patients. The cystic area of the tumors was hyperintense on T2WI in the remaining four patients, while one patient showed hemorrhage that was hyperintense on T1WI. The solid components of the GCTs show marked enhancement in all cases, while the cystic area of the tumors was observed without enhancement on contrast-enhanced images in four patients. Bone destruction of the adjacent vertebral body showed a homogeneous signal on T1WI and T2WI and marked enhancement on contrast-enhanced images. Conclusions Giant cell tumors of the mobile spine with invasion into adjacent vertebrae are an unusual imaging finding. Radiologists should be familiar with this imaging characteristic.

Abstract
Background The incidence of Candida bloodstream infections (BSIs), has increased over time. In this study, we aimed to describe the current epidemiology of Candida BSI in a large tertiary care hospital in Shanghai and to determine the risk factors of 28-day mortality and the impact of antifungal therapy on clinical outcomes. Methods All consecutive adult inpatients with Candida BSI at Ruijin Hospital between January 1, 2008, and December 31, 2018, were enrolled. Underlying diseases, clinical severity, species distribution, antifungal therapy, and their impact on the outcomes were analyzed. Results Among the 370 inpatients with 393 consecutive episodes of Candida BSI, the incidence of nosocomial Candida BSI was 0.39 episodes/1000 hospitalized patients. Of the 393 cases, 299 (76.1%) were treated with antifungal therapy (247 and 52 were treated with early appropriate and targeted antifungal therapy, respectively). The overall 28-day mortality rate was 28.5%, which was significantly lower in those who received early appropriate (25.5%) or targeted (23.1%) antifungal therapy than in those who did not (39.4%; P = 0.012 and P = 0.046, respectively). In multivariate Cox regression analysis, age, chronic renal failure, mechanical ventilation, and severe neutropenia were found to be independent risk factors of the 28-day mortality rate. Patients who received antifungal therapy had a lower mortality risk than did those who did not. Conclusions The incidence of Candida BSI has increased steadily in the past 11 years at our tertiary care hospital in Shanghai. Antifungal therapy influenced short-term survival, but no significant difference in mortality was observed between patients who received early appropriate and targeted antifungal therapy.

Abstract
For patients with sepsis and septic shock, it remains controversial when to restrict fluid intake and achieve a negative fluid balance. The present study aimed to evaluate the effects of the fluid intake volume during the first 24 h as well as fluid balance for 7 days on the prognosis of sepsis or septic shock. A total of 337 patients diagnosed with sepsis or septic shock at Ruijin Hospital (Shanghai, China) were enrolled in the present retrospective study. Patients with a low fluid intake volume during the first 24 h (fluid intake, 28.1±10.6 ml/kg) had lower in-hospital mortality rates (18.0 vs. 27.3%, P=0.043) and a shorter duration of mechanical ventilation [0 (0-6) vs. 3 (0-11), P=0.025] than the high-fluid volume intake group (62.6±17.6 ml/kg). Furthermore, survivors exhibited a daily negative net fluid balance from the second day (48 h), whereas non-survivors had a daily positive net fluid balance for 7 days, where fluid balance volumes were significantly lower in survivors compared with those in non-survivors. Finally, binary logistic regression analysis was used to determine whether the mean daily fluid balance (P<0.001) and the Acute Physiologic and Chronic Health Evaluation II score (P=0.048) were independent prognostic factors for patients with sepsis or septic shock. It was indicated that a low fluid intake volume during the first 24 h and a persistent negative fluid balance from the second day were associated with favorable outcomes. The mean daily fluid balance was an independent prognostic factor or patients with sepsis or septic shock.

Abstract
Brassica campestris L. is the important oil-bearing crop in China. Rapeseed cake is the main byproduct of rapeseed oil extraction. As the main active ingredient in rapeseed cake, sinapine has several important biological activities. Therefore, the inhibitory activity of sinapine on tyrosinase in vitro and its free radical-scavenging rate were determined. Tyrosinase activity in A-375 human melanocytes was also investigated and the effects of sinapine on the melanin content and its antioxidant effects on melanin biosynthesis were studied. The results showed that sinapine had significant antioxidant activity. Sinapine significantly inhibited A-375 human melanocytes in a dose-dependent manner. Sinapine inhibited melanin synthesis in A-375 cells by downregulating the mRNA and protein expression of TRP-1, TRP-2, and MITF factors. The results showed that rapeseed cake sinapine inhibited melanin production and could be used as a potential active ingredient in the development of whitening agents.

Abstract
Background Using standard vancomycin dosage in critically ill patients might lead to therapy failure and worse patient outcomes, augmented renal clearance (ARC) may be the leading risk factor. In this study, we comprehensively investigated the pharmacokinetics-pharmacodynamics (PK-PD) of vancomycin in critically ill patients with ARC, hoping to explore the precise and accurate dose adjustment method for vancomycin. Methods All critically ill patients tested for steady-state trough vancomycin serum concentrations during the recent 6 years in a tertiary level hospital were collected retrospectively and divided into ARC and non-ARC groups, respectively, according to creatinine clearance (CLcr). Serum vancomycin concentrations were measured by the fluorescence polarization immunoassay method. PK-PD parameters of vancomycin were recorded or calculated. The desired daily dose successful in achieving the lower target trough levels (10 mg/L) of vancomycin were investigated correspondingly. Results A total of 280 vancomycin concentrations were eligible for analysis. The ARC group (n=139) contained more male patients (64.7%) with average age and CLcr of 40 years old (P<0.05) and 180.8 mL/min (P<0.001), respectively. Those patients exhibited higher clearance (CL) and lower trough serum concentrations than the non-ARC patients under comparable daily doses of vancomycin. All the ICU patients demonstrated lower AUC24h values than the target level of 400 µg·h/mL, and this value showed a lower trend in the ARC group than the non-ARC group (232.9 vs. 316.2 µg·h/mL). Subtherapeutic trough concentrations of vancomycin (<10.0 mg/L) were observed in 77.7% and 68.8% of the ARC and non-ARC patients (P<0.05). The proportion of patients with a trough concentration of 10–15 and 15–20 mg/L was 17.9% and 4.3%, respectively, in the ARC group and 24.8% and 2.8%, respectively, in the non-ARC group., a daily dose of 46.0 and 35.5 mg/kg of vancomycin is needed, respectively, in the ARC and non-ARC group to achieve a target trough concentration of 10 mg/L. Conclusions A higher dose of vancomycin is needed in critically ill patients, especially those with ARC, and appropriate TDM-guided dose adjustment should be considered to achieve the targeted therapeutic range and to provide dosing guidance for this: patient population.

Abstract
Background Oxidative stress plays a pivotal role in the progress of severe acute pancreatitis (SAP). Vitamin C (VC) is the most important antioxidant in plasma. However, the effects of an intravenous administration of high-dose VC and the mechanisms by which it exerts its antioxidant function in an experimental model of SAP have not been determined. Methods Sodium taurocholate was used to induce rat pancreatic injury and AR42J cells injury. After the establishment of SAP model, SAP rat and injured AR42J cells were treated with VC. For the injured AR42J cells, small interfering RNA-mediated knockdown of NRF2 was conducted after VC treatment. The histopathological characteristics, the apoptosis of pancreatic acinar cells, oxidative stress markers and levels of enzymes, biochemical indicators, and inflammatory cytokines were examined in vivo and in vitro. Furthermore, the mortality of rats was assessed. Results In vivo and in vitro results demonstrated that VC treatment ameliorated apoptosis of pancreatic acinar cells, as evidenced by the increase in Bcl-2, Bcl-XL, and MCL-1 expressions and decrease in Bax and cleaved caspase-3 expression along with decreased TUNEL-positive cells. Also, we found that the elevation of MDA and decrease of SOD, GPx, GSH/GSSG, and T-AOC induced by SAP were reversed by VC treatment in vivo and in vitro, and VC treatment increased expressions of Nrf2, NQO1, and HO-1 in SAP model at protein and gene level, indicating that VC attenuated oxidative stress via the NRF2/NQO1/HO-1 pathway. Meanwhile, it was found that sodium taurocholate significantly induced the release of amylase, lipase, IL-1β, and IL-6 in rat plasma and AR42J cells, which were declined by VC treatment. In vitro results also revealed that these alterations in sodium taurocholate-injured AR42J cells due to VC treatment was attenuated by NRF2 knockdown. In addition, VC at a dose of 500 mg/kg decreased the levels of lactic acid, Cre, NGAL, AST, and ALT in the plasma of SAP rats, suggesting the improvement of renal and pancreatic injury and liver function of SAP rats. Furthermore, the mortality of SAP rats was 50%, which declined to 30% after VC treatment. Conclusions The present study suggests that high-dose of VC ameliorate pancreatic injury of SAP via the NRF2/NQO1/HO-1 pathway to inhibit oxidative stress.

Abstract
OBJECTIVE We aimed to investigate whether inhibition of MUC1 would aggravate sepsis-induced ALI, and explore the predictive value of plasma MUC1 for sepsis patients with or without ARDS. MATERIALS AND METHODS MUC1 siRNA pre-treatment was used to knockdown MUC1 expression in vitro. GO203 was used to inhibit the homodimerization of MUC1-C in vivo. Expression levels of MUC1, TLR 4 and HIF-1α were detected by Western blot. In addition, plasma MUC1 levels of enrolled patients were detected by ELISA on the day of admission and on the 3rd day. ROC curve was used to determine the predictive value of MUC1 in sepsis patients with ARDS. RESULTS Our results showed that inhibition of MUC1 could aggravate sepsis-induced acute lung injury and increase the expression of inflammatory cytokines in sera and BALF of sepsis mice. At the same time, we confirmed that inhibition of MUC1 could significantly decrease HIF-1α expression and thereby activate the expression level of TLR4. HIF-1α was a negative regulator of TLR-4. In addition, plasma MUC1 levels of sepsis patients with ARDS were significantly higher than those without ARDS and healthy adults. ROC curve showed that predictive value of plasma MUC1 on sepsis with ARDS on the 3rd day of enrollment was higher than the day of enrollment. CONCLUSION MUC1 could inhibit the expression of TLR-4 by stabilizing HIF-1α, thereby alleviate sepsis-induced lung injury and protect organ function. At the same time, elevated MUC1 levels in plasma had a good predictive valud on whether patients with sepsis would develop ARDS.

Abstract
BACKGROUND Fluid management is crucial to acute respiratory distress syndrome (ARDS) secondary to sepsis. However, choices of fluid resuscitation strategies and fluid input volumes remain a thorny problem. Our study aimed to elucidate the relationship between fluid balance and prognosis of ARDS patients secondary to sepsis. METHODS Our study included 322 sepsis patients from Ruijin Hospital between 2014 and 2018, and 84 patients were diagnosed as ARDS within 72 hours after onset of sepsis according to Berlin ARDS Definition. RESULTS Among the 322 sepsis patients, 84 (26.1%) were complicated with ARDS within 72 hours. ARDS patients had a lower oxygenation index (PaO2/FiO2 166.4±71.0 vs. 255.0±91.2, P<0.05), longer duration of mechanical ventilation (11 [6-24] days vs. 0 [0-0] days, P<0.05) than those without ARDS. Sepsis patients with ARDS showed daily positive net fluid balance during seven days compared with those without ARDS who showed daily negative net fluid balance since the second day with significant statistical differences. Among the 84 sepsis patients with ARDS, 58 (69.0%) died. Mean daily fluid input volumes were much lower in survivors than in non-survivors (43.2±16.7 mL/kg vs. 51.0±25.2 mL/kg, P<0.05) while output volumes were much higher in survivors (45.2±19.8 mL/kg vs. 40.2±22.7 mL/kg, P<0.05). Using binary logistic regression analysis, we found that the mean daily fluid balance was independently associated with mortality of sepsis patients complicating with ARDS (P<0.05). CONCLUSIONS Early negative fluid balance is independently associated with a better prognosis of sepsis patients complicated with ARDS.

Abstract
Purpose It has been reported that approximately 40% of ALI (acute lung injury) incidence resulted from sepsis. Paclitaxel, as a classic anti-cancer drug, plays an important role in the regulation of inflammation. However, we do not know whether it has a protective effect against CLP (cecal ligation and puncture)-induced septic ALI. Our study aims to illuminate the mitigative effects of paclitaxel on sepsis-induced ALI and its relevant mechanisms. Materials and methods The survival rates and organ injuries were used to evaluate the effects of paclitaxel on CLP mice. The levels of inflammatory cytokines were tested by ELISA. MUC1 siRNA pre-treatment was used to knockdown MUC1 expression in vitro. GO203 was used to inhibit the homodimerization of MUC1-C in vivo. The expression levels of MUC1, TLR 4 and p-NF-κB/p65 were detected by Western blot. Results Our results showed that paclitaxel improved the survival rates and ameliorated organ injuries especially lung injury in CLP-induced septic mice. These were accompanied by reduced inflammatory cytokines in sera and BALF (bronchoalveolar lavage fluid). We also found paclitaxel could attenuate TLR 4-NF-κB/p65 activation both in lung tissues of septic mice and LPS-stimulated lung type II epithelial cell line A549. At the upstream level, paclitaxel-upregulated expression levels of MUC1 in both in vivo and in vitro experiments. The inhibitory effects of paclitaxel on TLR 4-NF-κB/p65 activation were reversed in lung tissues of septic mice pre-treated with MUC1 inhibitor and in MUC1-knockdown A549 cells. Protection of paclitaxel on sepsis-induced ALI and decrease of inflammatory cytokines were also abolished by inhibition of MUC1. Conclusion Collectively, these results indicated paclitaxel could significantly alleviate acute lung injury in CLP-induced septic mice and LPS-stimulated lung type II epithelial cell line A549 by activating MUC1 and suppressing TLR-4/NF-κB pathway.

Abstract
BACKGROUND Blood pressure control is an essential therapy for patients with acute type B aortic dissection (ABAD) and should be maintained throughout the entire treatment. Thus, vast majority current guidelines recommend control the blood pressure to lower than 140/90 mmHg. Theoretically, a much lower target may further decrease the risk of propagation of dissection. However, some argued that too lower blood pressure would compromise the organ perfusion. Thus, there is no unanimous optimal target for blood pressure in patients with ABAD so far. The present study aimed to investigate the optimal blood pressure target for patients with ABAD, in the hope that the result would optimize the treatment of aortic dissection (AD). METHODS The study is a multi-center randomized controlled clinical trial. Study population will include patients with new diagnosed ABAD and hypertension. Blocked randomization was performed where intensive blood pressure control (<120 mmHg) with conventional blood pressure control (<140 mmHg) were allocated at random in a ratio of 1:1 in blocks of sizes 4, 6, 8, and 10 to 360 subjects. Interim analysis will be performed. The primary outcome is a composite in-hospital adverse outcome, including death, permanent paraplegia or semi- paralysis during the hospitalization, and renal failure requiring hemodialysis at discharge. While the secondary outcomes include the aortic size, lower extremity or visceral ischemia, retrograde propagation into aortic arch or ascending aorta, mortality in 6 months and 1 year, intensive care unit (ICU) length of stay, total length of hospital stay, creatinine level, and surgical or endovascular intervention. ETHICS AND DISSEMINATION The study was approved by the institutional review board of Sir Run Run Shaw Hospital (approval number: 20160920-9). Informed consent will be obtained from participants or their next-of-kin. The results will be published in a peer-reviewed journal and shared with the worldwide medical community. TRIAL REGISTRATION NCT03001739 (https://register.clinicaltrials.gov/).

Abstract
BACKGROUND The expression of dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) in renal tubular epithelial cells has been thought to be highly correlated with the occurrence of several kidney diseases, but whether it takes place in renal tissues during hemorrhagic shock (HS) is unknown. The present study aimed to investigate this phenomenon and the inhibitory effect of Vitamin C (VitC). METHODS A Sprague-Dawley rat HS model was established in vivo in this study. The expression level and location of DC-SIGN were observed in kidneys. Also, the degree of histological damage, the concentrations of tumor necrosis factor-μ and interleukin-6 in the renal tissues, and the serum concentration of blood urea nitrogen and creatinine at different times (2-24 h) after HS (six rats in each group), with or without VitC treatment before resuscitation, were evaluated. RESULTS HS induced DC-SIGN expression in rat tubular epithelial cells. The proinflammatory cytokine concentration, histological damage scores, and functional injury of kidneys had increased. All these phenomena induced by HS were relieved when the rats were treated with VitC before resuscitation. CONCLUSIONS The results of the present study illustrated that HS could induce tubular epithelial cells expressing DC-SIGN, and the levels of proinflammatory cytokines in the kidney tissues improved correspondingly. The results also indicated that VitC could suppress the DC-SIGN expression in the tubular epithelial cells induced by HS and alleviate the inflammation and functional injury in the kidney.

Abstract
BACKGROUND CpG islands in hepatitis B virus (HBV) genome are potential targets for methylation mediated gene silencing, and may be involved in the pathogenesis of HBV infection. To date, their characteristics in HBV quasispecies (QS) remain largely unknown. The purpose of this study was to investigate the characteristics of CpG islands in HBV QS. METHODS Forty patients diagnosed as acute hepatitis B (AHB, n = 10), immune-tolerant HBV carriers (IT, n = 9), chronic hepatitis B (CHB, n = 11), or acute on chronic liver failure (ACLF, n = 10), were enrolled in this case-control study. A total of 599 clones were isolated, and full-length HBV genomes were sequenced. RESULTS CpG island II (CGII) in AHB group was shorter in length and its QS heterogeneity was lower than that in the chronic infection group. Among the chronic infection subgroups, CGII and CpG island III (CGIII) in IT group were longer and their heterogeneity was lower compared to CHB and ACLF groups. Length of CGII correlated with HBV DNA levels positively while the complexity and diversity of CGII correlated with HBV DNA levels negatively. Moreover, CGII and CGIII were shorter in genotype B than those in genotype C, while QS complexity and diversity of either CGII or CGIII had no significant difference between genotype B and C. CONCLUSIONS Overall, our results suggest that the distribution, length and QS heterogeneity of CpG islands in full-length HBV genome differ across clinical phases of infection, of which the mechanism warrants further study.

Abstract
The aim of this study was to evaluate the association of GSTM1 null/present, GSTT1 null/present, and GSTP1 IIe105Val polymorphisms with the chemotherapy response and overall survival of advanced NSCLC. Two hundred and sixty-two patients with histologically confirmed advanced NSCLC (inoperable TNM stages IIIA, IIIB, and IV) were enrolled to this hospital-based study between May 2009 and May 2012. The GSTM1 null/present, GSTT1 null/present, and GSTP1 IIe105Val polymorphisms were genotyped by polymerase chain reaction coupled with restriction fragment length polymorphism. A logistic regression analysis revealed a correlation between the null genotype of GSTM1 and improved response to chemotherapy [odds ratio = 1.82; 95% confidence interval (CI) = 1.06-3.14]. Analyses with the Cox proportional hazards model also indicated that the null genotype of GSTM1 was associated with lower risk of death (hazard ratio = 0.40; 95%CI = 0.23-0.69). In conclusion, the null genotype of GSTM1 was found to be correlated with improved response to chemotherapy and lower risk of death in advanced NSCLC patients.

Abstract
BACKGROUND The best strategy for chronic hepatitis B patients with poor response to 48 weeks of Peginterferon-based therapy has been controversial and the predictive value of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA levels for determining the sustained virological response (SVR) of these patients is uncertain. OBJECTIVES To optimize management of these patients and evaluate the use of these serobiomarkers to predict SVR. STUDY DESIGN Eighty-one patients with an unsatisfactory response after 48 weeks of Peginterferon-based therapy were treated with extended Peginterferon therapy with or without nucleo(s) tide analogues (NAs), for a total of 96 weeks of Peginterferon treatment. HBsAg, HBeAg and HBV DNA levels were measured serially during the treatment and follow-up. RESULTS AND CONCLUSIONS Twenty-six of 81 patients (32.1%) attained SVR during the 72-week follow-up. The SVR rate was not statistically different between groups receiving 1-year prolongation of Peginterferon with or without NAs. The serum HBsAg cut-off of 1800IU/mL at week 48 had area under curve (AUC) of 0.727, and the serum HBsAg cut-off of 1500IU/mL, combined with HBeAg loss at week 72, had AUC of 0.753 to predict SVR during the follow-up. In conclusion, extended treatment with Peginterferon with or without NAs for patients with unsatisfactory response after 48 weeks of Peginterferon-based therapy is a promising strategy to achieve SVR, and quantitative serum HBsAg at week 48 and HBsAg level combined with HBeAg loss at week 72 of therapy can predict SVR to prolongation therapy with Peginterferon.

Abstract
Background Yeasts, mostly Candida, are important causes of bloodstream infections (BSI), responsible for significant mortality and morbidity among hospitalized patients. The epidemiology and species distribution vary from different regions. The goals of this study were to report the current epidemiology of Candida BSI in a Shanghai Teaching Hospital and estimate the impact of appropriate antifungal therapy on the outcome. Methods From January 2008 to December 2012, all consecutive patients who developed Candida BSI at Ruijin University Hospital were enrolled. Underlying diseases, clinical severity, species distribution, antifungal therapy and its impact on the outcome were analyzed. Results A total of 121 episodes of Candida BSI were identified, with an incidence of 0.32 episodes/1,000 admissions (0.21 in 2008 and 0.42 in 2012) The proportion of candidemia caused by non-albicans species (62.8%), including C. parapsilosis (19.8%), C. tropicalis (14.9%), C. glabrata (7.4%), C. guilliermondii (5.8%), C. sake (5.0%) was higher than that of candidemia caused by C. albicans (37.2%). The overall crude 28-day mortality was 28.1% and significantly reduced with appropriate empiric antifungal therapy administered within 5 days (P = 0.006). Advanced age (OR 1.04; P = 0.014), neutropenia < 500/mm3 (OR 17.44; P < 0.001) were independent risk factors for 28-day mortality, while appropriate empiric antifungal therapy (OR 0.369; P = 0.035) was protective against 28-day mortality. Conclusion The epidemiology of candidemia in Shanghai differed from that observed in Western countries. Appropriate empiric antifungal therapy influenced the short-term survival.

Abstract
To develop a procedure for cryopreservation of adult bovine testis tissue, the effects of dimethyl sulphoxide (DMSO), propylene glycol (PG), ethylene glycol (EG), and their concentrations (v/v), as well as different thawing temperatures, on the cell viability of bovine testis tissue after freezing/thawing were examined. The highest testicular cell viabilities came from the media containing DMSO (85.3 ± 1.2 percent), PG (82 ± 1.0 percent) and EG (83.4 ± 1.0 percent) at 10 percent concentration respectively. Using 10 percent DMSO gave significantly higher spermatogonia percentage (61.1 ± 1.2 percent, P < 0.001) than processing with 10 percent PG (54.3 ± 0.6 percent) or 10 percent EG (55 ± 1.8 percent) after differential plating. Thawing in water bath of 37 or 97-100 degree C also provided significantly higher viabilities (85.1 ± 1.0, 85 ± 1.0 percent, P < 0.01, respectively) and spermatogonia percentages (56.6 ± 2.0, 56.6 ± 2.6 percent, P < 0.01, respectively) than that thawing at 4C (23.4 ± 0.8 percent for total viability, 8.97 ± 1.0 percent for spermatogonia percentage). Collectively, 10 percent DMSO and thawing in 37-100 degree C water baths were appropriate for the cryopreservation of bovine testicular tissue and subsequent spermatogonia enrichment.

Abstract
We study the transmission of electric energy through a circular cylindrical elastic shell by acoustic wave propagation and piezoelectric transducers. Our mechanics model consists of a circular cylindrical elastic shell with finite piezoelectric patches on both sides of the shell. A theoretical analysis using the equations of elasticity and piezoelectricity is performed. A trigonometric series solution is obtained. Output voltage and transmitted power are calculated. Confinement and localization of the vibration energy (energy trapping) is studied which can only be understood from analyzing finite transducers. It is shown that when thickness-twist mode is used the structure shows energy trapping with which the vibration can be confined to the transducer region. It is also shown that energy trapping is sensitive to the geometric and physical parameters of the structure.

Abstract
AIM: To identify the two polymorphisms of microsomal triglyceride transfer protein (MTP) gene in the Chinese population and to explore their correlation with both hepatitis B virus (HBV) self-limited infection and persistent infection.
METHODS: A total of 316 subjects with self-limited HBV infection and 316 patients with persistent HBV infection (195 subjects without familial history), matched with age and sex, from the Chinese Han population were enrolled in this study. Polymorphisms of MTP at the promoter region -493 and at H297Q were determined by the allele specific polymerase chain reaction (PCR).
RESULTS: The ratio of males to females was 2.13:1 for each group and the average age in the self-limited and chronic infection groups was 38.36 and 38.28 years, respectively. None of the allelic distributions deviated significantly from that predicted by the Hardy-Weinberg equilibrium. There was a linkage disequilibrium between H297Q and -493G/T (D’ = 0.77). As the χ2 test was used, the genotype distribution of MTP-493G/T demonstrated a significant difference between the self-limited infection group and the entire chronic group or the chronic patients with no family history (χ2 = 8.543, P = 0.015 and χ2 = 7.199, P = 0.019). The allele distribution at the MTP-493 position also demonstrated a significant difference between the study groups without family history (χ2 = 6.212, P = 0.013). The T allele emerged as a possible protective factor which may influence the outcomes of HBV infection (OR: 0.59; 95% CI: 0.389-0.897).
CONCLUSION: The polymorphism of the MTP gene, T allele at -493, may be involved in determining the HBV infection outcomes, of which the mechanism needs to be further investigated.

Abstract
We report herein a case of Morganella morganii-associated acute purulent pericarditis that developed 3 years after allogenic bone marrow transplantation. The patient was successfully treated with surgical drainage and cefotaxime for 6 weeks. Splenectomy and immunosuppression for chronic GVH-D are likely to have favored the development of this rare infectious complication after BMT. M. morganii should be added to the list of bacteria causing purulent pericarditis, especially in immunocompromised hosts.

Abstract
Changes of beta-endorphin (beta-EP) and its mRNA in pituitary (P), hypothalamus (HT), lymphocytes (LC) and blood plasma (BP) during cold acclimation of SD male rats were studied by beta-EP mRNA dot blot, RP-HPLC and beta-EP radio-immunoassay (RIA). Experimental results showed: (1) After cold-exposure for 1 week pituitary beta-EP mRNA increased significantly with the appearance of stimulated cellular immune function. (2) beta-EP mRNA in hypothalamic immune center and peripheral LC increased when cold acclimation of animals was established for a cold exposure of 2 weeks (C2W). (3) From C2W onward, plasma beta-EP also continued to increase, indicating an augmented state of cellular immune function. As LC and plasma beta-EP product continued to show increase, pituitary beta-EP mRNA content recovered to control level from C2W onward possibly due to a feedback mechanism through LC-P-HT axis.

Abstract
Interviews with 564 patients with stomach cancer and 1,131 controls in an area of China where gastric cancer rates are high revealed a significant reduction in gastric cancer risk with increasing consumption of allium vegetables. Persons in the highest quartile of intake experienced only 40% of the risk of those in the lowest. Protective effects were seen for garlic, onions, and other allium foods. Although additional research is needed before etiologic inferences can be made, the findings are consistent with recent reports of tumor inhibition following administration of allium compounds in experimental animals.

Abstract
A case-control investigation involving interviews with 564 stomach cancer patients and 1131 population-based controls was conducted to evaluate reasons for the exceptionally high rates of stomach cancer in Linqu, a rural county in Shandong Province in northeast China. Daily consumption of sour pancakes, a fermented indigenous staple, was associated with a 30% increase in risk. Risks of stomach cancer were also increased by 2- to 3-fold among persons with prior chronic gastritis or gastric ulcer, by 80% among those with stomach cancer in a family member, by 50% among men who smoked one or more packs of cigarettes/day, by 40% among those who preferred salty foods, and by 50% among families with moldy grain supplies. In contrast, risks tended to decrease in proportion to increasing consumption of fresh vegetables and fruits. This protective effect was more pronounced for vegetables, with those in the highest quartile of intake at less than one-half the risk of those in the lowest. Stomach cancer risks also declined with increasing dietary intake of carotene, vitamin C, and calcium, but not retinol. These findings provide leads to dietary factors that contribute to the high rates in Linqu, where stomach cancer is the leading cause of cancer and has not yet begun to decline as in other parts of the world.

Abstract
In anther culture of Panax ginseng, its callus formation showed a wide adaptability to culture media. Large numbers of calli were induced on media exhibiting better effects of induction. Supplements of 5 mg 2,4-D/1 and 1 mg KT/1 to the media proved to be much effective. Regeneration of the whole plantlets from anther culture of Panax ginseng is usually quite difficult. During the past three years, however, sixteen of the 100 medium formulae tested were proved to be suitable. The formulae of MS + 0.5 mg BA/1 + 2 mg GA/1 + 1000 mg LH/1 + 3% sucrose were considered good and effective. A visibly differentiated body, which was light-milky white and later turned into a light green spot, was formed 40 days after the callus was transferred to the differentiation media. This body differentiated subsequently into buds, roots and, eventually, seedlings. The embryoid clones have been established in order to maintain its ability of continual differentiation into plantlets through successive culturings of many generations. The test-tube ginseng thus formed were transferred to regular flowerpots and grew well. Based upon chromosome examination of the callus cells and the root tips, we tentatively affirmed that the majority of these regenerated from anther of Panax ginseng were originated from pollen cells.
