ABSTRACT

Objective:To construct a simple, precise and personalized comprehensive nomogram for prediction the risk of multidrug-resistant tuberculosis (MDR-TB) and to evaluate its prediction value among individuals with previous tuberculosis history (PTBH).Methods:A matched case-control study (1∶2 ratios) was performed in 1 881 patients with PTBH treated in 12 designated tuberculosis hospitals in Hangzhou City between January 1, 2005 and December 31, 2019, and there were 1 719 patients in training set, and 162 in validation set. A multivariable Cox regression analysis was used to evaluate independent predictors for the incident of MDR-TB in individuals with PTBH. A comprehensive nomogram was developed based on the multivariable Cox model. The accuracy of the prediction was assessed using concordance index (C-index), calibration curve and area under the receiver operator characteristic (ROC) curve.Results:The nomogram constructed based on the multivariable Cox regression model incorporated 10 independent predictors of the risk of MDR-TB. A history of direct contact (grade 1, 0-100.0 points) ranked on the top of all risk factors, followed by duration of positive sputum culture (grade 2, 0-84.5 points), unfavorable treatment outcome (grade 3, 0-52.0 points), human immunodeficiency virus infection (grade 4, 0-48.5 points), retreated tuberculosis history (grade 5, 0-40.0 points), non-standardized treatment regimens of retreated tuberculosis (grade 6, 0-32.5 points), duration of pulmonary cavities (grade 7, 0-31.0 points), passive mode of tuberculosis case finding (grade 8, 0-25.0 points), age<60 years (grade 9, 0-17.5 points), and standard frequencies of chest X-ray examination (grade 10, 0-14.0 points). The C-indexes of this nomogram for the training and validation sets were 0.833 (95% confidence interval ( CI) 0.807-0.859) and 0.871 (95% CI 0.773-0.969), respectively, indicating that the nomogram had good fitting effect. The calibration curves for the risk of incident MDR-TB showed an optimal agreement between nomogram prediction and actual observation in the training and validation sets, respectively.The areas under ROC curve of the 1-year, 5-year, and 10-year MDR-TB risk probability of the training set were 0.904, 0.921, and 0.908, respectively, and those of the validation set were 0.954, 0.970, and 0.919, respectively. Conclusion:Through this nomogram model, clinicians could precisely predict the risk of incident MDR-TB among individuals with PTBH in the clinical practice.

ABSTRACT

OBJECTIVE@#To investigate and compare the clinical efficacies of remnant-preserving and remnant-non-preserving, remnant-non-preserving remnant segment preserving and remnant root preserving with anterior cruciate ligament reconstruction.@*METHODS@#From March 2014 to December 2017, 204 patients with anterior cruciate ligament (ACL) injuries were treated by single-bundle ACL reconstruction with hamstring tendon autograft. According to the different methods of remnant preservation, the procedures were divided into remnant segment preserving group (A), remnant root preserving group (B), and remnant-non-preserving group (C). There were 37 males and 39 femalesin group A aged from 16 to 43 years old with an average of (28.80±5.41) years old. The time from injury to operation ranged from 2 to 11 weeks with an average of (3.68±1.04) weeks. In group B, there were 39 males and 25 females aged from 18 to 41 years old with an average of (28.42±5.60) years old. The time from injury to operation ranged from 2 to 10 weeks with an average of (3.36±1.68) weeks. In group C, there were 37 males and 27 females aged from 18 to 43 years old with an average of (29.10±6.11) years old. The time from injury to operation ranged from 3 to 11 weeks with an average of (3.54±1.46) weeks. The range of motion (ROM) of the knee was used to assess the range of extension and flextion of the knee at pre-operation and 24 months after operation. Lysholm score and the international knee documentation committee (IKDC) score were used to assess the knee function. The differences among three procedures were judged by comparing among the three groups at 6, 12 and 24 months postoperatively.@*RESULTS@#All incisions got a one stage healing, and no complications, such as vascular injury, nerve damage and articular infect or the like, occurred. All the patients were followed up, and the follow-up duration of group A ranged from 24.00 to 45.96 months with a mean of (35.52±14.40) months;the follow up duration of group B ranged from 27.96 to 48.00 months with a mean of (37.56±10.68) month;and the follow up duration of group C ranged from 24.00 to 66.00 months with a mean of (37.08±13.44) month. There were no significant differences in follow up time among three groups (@*CONCLUSION@#Compared with remnant-non-preserving group, the residual tissue of anterior cruciate ligament is preserved, which is conducive to promote the healing and remodeling of tendon graft and accelerate the recovery of joint function. Proper fixation of residual tissue and restoration of its tension are the key factors affecting the postoperative efficacy.

ABSTRACT

The incidence of posterior instability of shoulder joint was significantly lower than that of anterior instability, but the clinical diagnosis and treatment was difficult, and the misdiagnosis and missed diagnosis rate were high. Its etiology, clinical manifestation and treatment strategy are totally different from the anterior instability. Therefore, the deep understanding of the anatomical structure around the shoulder joint, the mastery of the examination method, and the classification of the shoulder instability based on the anatomy and injury mode are of great importance to improve the accuracy of diagnosis. CT three-dimensional reconstruction is helpful to evaluate the defect of humeral head and glenoid bone, and MRA is helpful for the accurate diagnosis of posterior glenoid lip and joint capsule. The treatment was divided into conservative treatment and surgical treatment. Conservative treatment is recommended for muscular instability. Surgical treatment is recommended for traumatic and dysplastic instability. Different operative methods should be performed according to the injury of glenoid side or humeral head side. According to the condition of bone defect, soft tissue operation, bone grafting or osteotomy were performed to reconstruct the posterior stable structure of the glenoid injury; according to the area of the anterior bone defect, bone grafting or subscapular muscle packing were performed to the head of humerus defect. The former has the advantages of short learning curve and firm fixation, while the latter has the advantages of minimally invasive operation and the ability to observe the lesions from multiple angles and accurately control the location of bone masses. This paper summarizes the above problems.

ABSTRACT

OBJECTIVE@#To investigate the efficacy, safety and prognosis of auto-HSCT between classical and modified conditioning regimen in patients with B-cell non-Hodgkin lymphoma.@*METHODS@#36 patients diagnosed as B-cell non-Hodgkin lymphoma treated with autologous hematopoietic stem cell transplantation from January 2015 to June 2018 in Tianjin Cancer Hospital were retrospectively analyzed. The patients were divided into two groups: Idarubicin group and non-Idarubicin group. The overall survival (OS), progression-free survival (PFS), adverse reactions and hematopoietic reconstitution time between the two groups were compared. Survival analysis was performed by using the Kaplan-Meier method. Log-rank test was used for comparison between groups, and Cox regression was used for multivariate analysis.@*RESULTS@#The median follow-up time was 29 months. Among these 36 patients with B-cell non-Hodgkin lymphoma before transplantation, 21 patients achieved CR and 15 patients achieved PR. The reconstitution time of neutrophil (P>0.05) and platelet (P>0.05) was not significantly different between Idarubicin and non-Idarubicin group. Also, the adverse reactions were not significantly different between two groups. The addition of idarubicin showed not aggravate the adverse reactions of patients. The OS and PFS of patients with idarubicin was longer than that of patients without idarubicin. The multivariate analysis showed that, the modified conditioning regimen and the remission state before transplantation were closely associated with prognosis.@*CONCLUSION@#The above-mentioned results indicated that the combination of modified conditioning regimen with idarubicin can lengthen the OS and PFS of the patients significantly, and show not aggravate of bone marrow inhibition, moreover, the hematopoietic reconsititution time show not lengthen, which means that it can be a safe and effective choice for autologous HSCT in the patients with B cell non-Hodgkin lymphoma.

ABSTRACT

OBJECTIVE@#To analyze the clinical and pathological characteristics of primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL) patients, and to explore the factors affecting the patients' survival and prognosis.@*METHODS@#The clinical data of 219 patients with PGI-NHL diagnosed in our hospital from March 2009 to April 2016 was collected and retrospectively analyzed. Survival analysis was performed by using the Kaplan-Meier method. Log-rank test was used for comparison among the groups, and Cox regression was used for multivariate analysis.@*RESULTS@#Among the 219 patients with PGI-NHL, 126 patients were males and 93 patients were females. 182 patients were IPI 0 to 2 and 37 patients were IPI 3 to 5. There were 205 cases (93.6%) of B cell phenotype and 14 cases (6.4%) of T cell phenotype. 140 patients (63.9%) were patients with primary gastric NHL, including 85 DLBCL and 19 MALT. 79 cases (36.1%) were patients with primary intestinal NHL, including 46 DLBCL, 4 MALT, 7 FL, 3 MCL and 4 Burkitt lymphoma. 23 cases were HP positive and received anti-HP therapy. 57 cases and 32 cases received surgery and chemotherapy respectively. 84 cases received combination treatment of surgery and chemotherapy and 11 cases received combination treatment of radiotherapy and chemotherapy. Overall survival (OS) of indolent B-cell non-Hodgkin's lymphoma was longer than that of invasive B-cell non-Hodgkin's lymphoma, which shows better prognose. Kaplan-Meier analysis showed that there was no difference between progression-free survival (PFS) and OS in the patients with different origin sites, age and sex. There was no significant difference in PFS between B-cell and T-cell-derived patients, whereas OS of B-cell-derived PGI-NHL patients was longer than that of T-cell-derived PGI-NHL patients. The OS and PFS of patients with IPI 0-2 were longer than those of patients with IPI 3-5. According to Lugano and Ann Arbor staging systems, there was no difference in prognosis of patients between phase I/II and III/IV. The prognosis of patients treated with surgery alone was worse than that of patients treated with combination therapy, and the prognosis of patients with surgery combined with chemotherapy was not significantly different from that of patients with chemotherapy alone.@*CONCLUSION@#B-cell phenotype, indolent and low IPI score lymphoma indicate better prognosis, while that of different origin site, sex and age shows no different in prognosis. Surgery is used only for emergency case or pathological materials, and these patients should be treated with chemotherapy-based combined treatment.

ABSTRACT

OBJECTIVE@#To explore the effects of single anterior approach under shoulder arthroscopy in the treatment of Bankart injury, and to provide a scheme to overcome the difficulties and simplify the operation process.@*METHODS@#From July 2016 to January 2019, 62 patients with recurrent dislocation caused by Bankart leision were treated under shoulder arthroscopy, including 50 males and 12 females, ranging in age from 19 to 44 years old with an average age of (26.5±6.1) years old. There were 25 cases of left shoulder and 37 cases of right shoulder. The patients were divided into two groups according to the operation mode, 35 patients in the front modified single approach group (experimental group) and 27 patients in the traditional double approachgroup (control group). The results of the operation were evaluated by assessing the preoperative and postoperative ASES scores of the shoulder joint, and the time of the approach establishment and the overall operation process was recorded to evaluate whether the operation time of the experimental group was shortened.@*RESULTS@#Three patients were lost during the follow-up after operation, and except for one case of re-dislocation, all patients achieved satisfactory results without neurovascular injury and other complications. The patients were followed up before operation and 3, 6, 12 months after operation, and the ASES scores were significantly enhanced at the latest follow-up compared with those of before operation. The time of establishing surgical approach in the experimental group was (7.5±1.5) minutes, which was shorter than that of control group (13.7±1.2) minutes.@*CONCLUSION@#The improved technique of single-channel anterior approach has the advantages of reducing the surgical incision and shortening the operationtime while ensuring the quality of the operation, which is worthy of popularization and application.

ABSTRACT

Objective:To investigate the emergency surgical strategies for patients with acute abdomen during the Corona Virus Disease 2019 (COVID-19) outbreak.Methods:The retrospective and descriptive study was conducted. The clinical data of 20 patients with acute abdomen who were admitted to the Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology between January 18, 2020 and February 10, 2020 were collected. There were 13 males and 7 females, aged from 25 to 82 years, with an average age of 57 years. All the patients with emergency surgeries received pulmonary computed tomography (CT) examination before surgery, and completed nucleic acid detection in throat swab if necessary. Patients excluded from COVID-19 underwent regular anesthesia, suspected and confirmed cases were selected a proper anesthesia based on their medical condition and surgical procedure. Patients excluded from COVID-19 underwent emergency surgeries following the regular procedure, suspected and confirmed cases underwent emergency surgeries following the three-grade protection.Observation indicators: (1) surgical situations; (2) postoperative situations. Measurement data with normal distribution were represented as average (range). Count data were described as absolute numbers.Results:(1) Surgical situations: of the 20 patients with acute abdomen, 16 patients were excluded from COVID-19, and 4 were not excluded. All the 20 patients underwent emergency abdominal surgeries successfully, of whom 2 received surgeries under epidural anesthesia (including 1 with open appendectomy, 1 with open repair of duodenal bulbar perforation), 18 received surgeries under general anesthesia (including 9 with laparoscopic repair of duodenal bulbar perforation, 3 with open partial enterectomy, 3 with laparoscopic appendectomy, 1 with laparoscopic left hemicolectomy, 1 with laparoscopic right hemicolectomy, 1 with cholecystostomy). The operation time of patients was 32-194 minutes, with an average time of 85 minutes. The volume of intraoperative blood loss was 50-400 mL, with an average volume of 68 mL. (2) Postoperative situations: 16 patients excluded from COVID-19 preopratively were treated in the private general ward postoperatively. One of the 16 patients had fever at the postoperative 5th day and was highly suspected of COVID-19 after an emergency follow-up of pulmonary CT showing multiple ground-glass changes in the lungs. The patient was promptly transferred to the isolation ward for treatment, and results of nucleic acid detection in throat swab showed double positive. Medical history described by the patient showed that the patient and family members were residents of Wuhan who were not isolated at home during the epidemic. There was no way to confirm whether they had a history of exposure to patients with COVID-19. Medical staffs involved in this case did not show COVID-19 related symptoms during 14 days of medical observation. The other 15 patients recovered well postoperatively. The 4 patients who were not excluded from COVID-19 preoperatively based on medical history and results of pulmonary CT examination were directly transferred to the isolation ward for treatment postoperatively. They were excluded from COVID-19 for two consecutive negative results of nucleic acid detection in the throat swab and recovered well. Two of the 20 patients with acute abdomen had postoperative complications. One had surgical incision infection and recovered after secondary closure following opening incision, sterilizing and dressing, the other one had intestinal leakage and was improved after conservative treatment by abdominal drainage. There was no death in the 20 patients with acute abdomen.Conclusions:Patients with acute abdomen need to be screened through emergency forward. Patients excluded from COVID-19 undergo emergency surgeries following the regular procedure, and patients not excluded from COVID-19 undergo emergency surgeries following the three-grade protection. The temperature, blood routine test and other laboratory examinations are performed to monitor patients after operation, and the pulmonary CT and throat nucleic acid tests should be conducted if necessary. Patients excluded from COVID-19 preopratively are treated in the private general ward postoperatively, and they should be promptly transferred to the isolation ward for treatment after being confirmed. Patients who are not excluded from COVID-19 preoperatively based on medical history should be directly transferred to the isolation ward for treatment postoperatively.

ABSTRACT

Objective@#To investigate whether silencing UCP2 can sensitize cervical cancer cell line Siha to radiation.@*Methods@#Siha cells were transfected with UCP2 siRNA and then irradiated by X-ray. The radiosensitivity of Siha cells was verified by colony formation, CCK-8, apoptosis and immunofluorescence assays. The mitochondrial membrane potential and the production of reactive oxygen species (ROS) were detected to further explore the related mechanism.@*Results@#RT-PCR and Western blot assays showed that the expression of UCP2 in Siha cells was increased after irradiation and the UCP2 siRNA successfully silenced the expression of UCP in cells. According to the survival curves, the D0, Dq, N and SF2 were 1.54, 1.31, 2.31 Gy and 0.52 for siUCP2 group, 2.50, 3.64, 4.30 Gy and 0.83 for blank control group, and 3.34, 2.16, 1.91 Gy and 0.69, for siNC group, respectively. The radiosensitivity enhancement ratio of silent group was 0.62 and 0.46, compared with blank control group and negative control group, respectively. The proliferative activity of cells in the silent group was lower than that in the control group (t=13.2, P<0.05). Apoptosis levels in the silent group were significantly higher than those in the control group after irradiation(t=3.14, P<0.05). At 4 h after irradiation, the ROS production in the silent group was significantly higher than that in the control group (t=19.10, P<0.05). At 24 h after irradiation, the mitochondrial membrane potential of Siha cells in the silent group was significantly lower than that in the control group (t=4.18, P<0.05).@*Conclusions@#The radiosensitivity of Siha cells is enhanced after UCP2 silencing, and thus UCP2 may applicable as a new target for radiosensitization of cervical cancer cells.

ABSTRACT

Tripartite motif 5 (TRIM5) plays a significant function in autophagy and involves in immune and tumor processes. While the function of TRIM5 remains poorly understood in glioma. We purpose to evaluate the possible prognostic role of TRIM5 in glioma via bioinformatics analyses. The database clinical samples of glioma in this study included low grade glioma (LGG) and glioblastoma multiforme (GBM). TRIM5 expression in glioma tissues were explored in Oncomine, GEPIA and The Cancer Genome Atlas (TCGA) databases. Survival analysis and the multivariate Cox regression analysis of TRIM5 based on TCGA were used to evaluate the prognostic role of TRIM5. The protein networks of TRIM5 was detected by STRING database. KEGG enrichment analyses were performed to predict the potential molecular pathways of TRIM5 in glioma. In addition, immune infiltration analysis was conducted by CIBERSORT and TIMER databases. We found that TRIM5 was strongly increased in glioma samples compared with normal samples in Oncomine, GEPIA and TCGA databases. Higher TRIM5 was significantly contributed to worse overall survival (OS) in LGG+GBM patients and LGG patients, while was no correlated with OS of GBM patients. Interaction networks analysis identified that IRF3, IRF7, OAS1, OAS2, OAS3, OASL, GBP1, PML, BTBD1 and BTBD2 proteins were contacted with TRIM5. Moreover, KEGG revealed that apoptosis and cancer- and immune-related pathways were enriched with elevated TRIM5. Specifically, TRIM5 could influence the immune infiltration levels, such as activated NK cells, monocytes, activated mast cells and macrophages in glioma. In conclusion, our data indicated that TRIM5 was upregulated in glioma tissues and associated with poor prognosis and immune infiltration. TRIM5 may be acted as a biomarker in prognosis and immunotherapy guidance of glioma.

ABSTRACT

The treatment of severe trauma, especially multiple injuries, requires multidisciplinary collaboration. The current study aims to highlight the challenges of consultation mode for severe trauma in general hospitals and emphasizes the need to create a new temporary-sustainable team. It suggests developing an information consultation mode and enforcing the fine management to improve the quality and safety of the medical treatment. The management mode of a temporary-sustainable team will reduce the cost and improve the treatment efficiency. Overall, a temporary-sustainable team has significant advantages over a traditional multidisciplinary team for severe trauma treatment.
