Objective:To investigate the effects of IP10(IFN-? inducible protein 10,CXCL10) on anti-tumor immune response and to explore its mechanisms involved in.Methods:A mammary carcinoma cell line 4T1 was transfected with pcDNA3-IP10(IP10-4T1) by electrophoration and positive clones were screened in the presence of G418.Growth kinetics of IP10-4T1 cells was observed in vitro and in vivo.Survival rate among the animals was determined by daily assessment.Proliferation activity of lymphocytes was analyzed with()~3H-TdR incorporation.The phenotypes of lymphocytes isolated from tumors by ficoll density gradient centrifugation were assayed by flow cytometry.Results:The growth rate of IP10-4T1 cells was similar with that of parental 4T1 cells and neo-vector transfected 4T1 cells in vitro.Growth of the tumors formed by IP10-4T1 cells was inhibited in vivo.Compared to those of controls,the size and the weight of the tumors formed by IP10-4T1 cells decreased significantly 35 days post tumor transplantation(P

Mice were divided into 3 groups:heavy infection group with 80 mice each was fed with 400 muscle larvae of Trichinella spiralis,light infection group with 60 mice each was fed by 200 larvae,and uninfected control (60 mice). The content of Cu,Zn and Fe in the dorsal hair samples was measured in the week of 1,3,5,7,9,11,13 and 15 after infection. Results indicated that the content of Zn,Cu and Fe in the two experimental groups reduced considerably in comparison to the control(P

Objective:To explore the efficacy and safety of unrelated mismatched hematopoietic stem cell transplantation(HSCT)for thalassemia major.Methods:For this retrospective cohort study, 15 patients with β-thalassemia major underwent unrelated mismatched HSCT between January 2018 and April 2022. There were 8 males and 7 females with a median age of 7(3-12)years and a median ferritin level of 3 417.3(223-14 485)μg/L. The conditioning regimens on the basis of fludarabine(Flu), busulfan(Bu)and cyclophosphamide(CTX)and GVHD prophylaxis on the basis of cyclosporine(CsA), mycophenolate mofetil(MMF), anti-human thymocyte immunoglobulin(ATG)plus low-dose post-cyclophosphamide(PTCy)and mesenchymal stem cells were offered.Results:Up until April 1, 2022, 15 children were successfully implanted during a median follow-up period of 24.1(11-49)months and all of them achieved stable donor chimerism. The median time to neutrophil and platelet engraftment were 12(11-22)and 14(8-38)days respectively. Except for 2 deaths, 13 cases survived. The estimated 2-year probability of overall survival(OS)and thalassemia-free survival(TFS)were both 86.67%. There were 5 cases of acute graft versus host disease (aGVHD) below grade Ⅱ, 2 cases of grade Ⅲ to Ⅳ aGVHD, and 3 cases of localized chronic graft versus host disease (cGVHD) after transplantation. No gengralized cGVHD occurred. Both cytomegalovirus and Epstein-Barr virus were activated in five recipients.Conclusions:Unrelated mismatched donor HSCT is both safe and feasible for thalassemia major.

OBJECTIVE: To explore the clinical and molecular characteristics of a child with Congenital disorders of glycosylation (CDG). METHODS: A 4-month-old boy who had presented at the Children's Hospital Affiliated to Zhejiang University Medical School on December 31, 2019 due to feeding difficulties after birth was selected as the study subject. High-throughput sequencing was carried out for the patient, and real-time qPCR was used for validating the suspected deletion fragments and the carrier status of other members of his family. RESULTS: High-throughput sequencing revealed that the child had lost the capture signal for chrX: 153 045 645-153 095 809 (approximately 50 kb), which has involved 4 OMIM genes including SRPK3, IDH3G, SSR4 and PDZD4. qPCR verified that the copy number in this region was zero, while that of his elder brother and parents was all normal. CONCLUSION The deletion of the fragment containing the SSR4 gene in the Xq28 region probably underlay the SSR4-CDG in this child.

Brain atlas provides a spatial reference system on which other images can be interpreted in a consistent way, and it is essential for the brain imaging research. However, because of the differences in structure between occidental and oriental brains, the brain atlas based on Western populations, e. g., the International Consortium for Brain Mapping's 154 T1 Weighted Average Atlas, may not be appropriate for other ethnic groups. Therefore, in the present study, we produce an average brain atlas which is based on the data collected from 100 healthy Chinese volunteers. The differences in brains between the Chinese population and the Western population were also investigated. Comparatively,Chinese brains are wider and shorter in size, and smaller in volume.

Objective:To explore the locations of the lumbosacral nerve roots by use of the magnetic stimulation.Methods:Thirty healthy subjects were studied. The projections of the right L 2 to S 1 intervertebral foramina on their body surfaces were determined manually with ultrasound assistance. Magnetic stimulation was applied to different nerve root segments to induce compound muscle action potentials (CMAP) in the vastus medialis, tibialis anterior, and gastrocnemius muscles of the lower limbs. The changes in latency, amplitude, and motor threshold were observed. Results:Magnetic stimulation on the L 2-L 3 segment resulted in a significant direct excitation of the vastus medialis. That on the L 5-S 1 segment evoked a significant direct excitatory effect on the tibialis anterior and gastrocnemius, with a motor threshold below 40%, an amplitude exceeding 1mV, and many effective responses. However, during the magnetic stimulation on the L 4 segment, the amplitude of the vastus medialis was above 1mV, with no significant differences in the number of effective responses among the muscle groups. Moreover, there was a stepwise change in the latency of effective muscle responses to magnetic stimulation at different segments. The CMAP latencies of 12+ ms for the tibialis anterior and 13+ ms for the gastrocnemius indicated activation of the L 5 and L 4 nerve roots, respectively, while those of 6+ ms, 7+ ms, and 8+ ms for the vastus medialis suggested activation of the L 4, L 3, and L 2 nerve roots, respectively. Conclusions:Based on the responses (CMAP latency, amplitude and motor threshold) of the vastus medialis, tibialis anterior and gastrocnemius to magnetic stimulation at different L 2 to S 1 segments, the spinal nerve root segments responsible for innervation can be inferred.

Objective To investigate the bacterial resistance in nationwide and understand the distribution of bacterial and resistance trend.MethodsThe 6507 clinical isolates were collected from 19 hospitals in 17 cities.The susceptibility tests were performed using agar dilution method recommended by Clinical and Laboratory Standards Institute (CLSI) in central laboratory.The values of MIC50,MIC90 and MICrange were calculated by SPSS 17.0 and the susceptibilities of isolates to antimicrobial agents were determined by using CLSI (2010) guideline.Of all 6507 isolates,4691 strains were collected from target wards and 1816 were isolated from others wards.ResultsAmong 4691 strains,1156 were Gram-positive (24.6％ ) and 3535 were Gram-negative (75.4％).Based on the minimum inhibitory concentration results,the prevalence of methicillin resistant Stapylococcus aureus and methicillin resistant Stapylococcus epidermidis are 51.6％ ( 325/630 ) and 87.0％ ( 228/262 ) respectively.Staphylococci showing intermediate or full resistance to vancomycin were not observed. Coagulase negative Staphylococci showed 2.5％ (16/642)intermediate rate and 1.6％ ( 10/642 ) full resistance rate to teicoplanin,and showed 0.5％ ( 3/642 )resistance rate to linezolid.Antibiotic resistance rate of Enterococcus faecalis to ampicillin was 17.1％(19/111),while the resistance rate of Enterococcus faecium to ampicillin reached up to 85.0％(164/193).Three Enterococcus faecium were resistant to glycopeptides.The prevalence of penicillin resistance Streptococcus pneumoniae and penicillin intermediate Streptococcus pneumoniae were 41.2％ ( 145/352) and 37.2％ (131/352) respectively based on oral penicillin criterion,while the prevalence were 0.0％ (0/352) and 6.0％(21/352) based on vein to non-meningitis criterion.A vast majority of Enterobacteriaceae maintained high susceptibility to carbapenems,with resistance rate less than 2.0％.In addition,tigecycline,moxalactam,fosfomycin and amikacin displayed desirable antibacterial activity against Enterbacteriaceae,and resistance rates to these drugs were all less than 10.0％.For non-fermenting Gramnegative isolates,resistance rate of Pseudomonas aeruginosa and Acinetobacter baumannii to imipenem were 23.1％ ( 139/601 ) and 53.5％ (419/784) respectively.Resistance rate of Acinetobacter baumannii was much higher than that during the period 2007 - 2008.Colistin,tigecycline,minocycline and fosfomycin demonstrated good antibacterial activity against Acinetobacter baumannii in vitro.Conclusions Compared with MOHNARIN 2007 -2008year surveillance results, significant increase in resistance rate of Acinetobacter baumannii was demonstrated.Resistant strains to linezolid and tigecycline were found.Bacterial resistance has been a widespread problem in our country,which requires much more attention.

Objective: To investigate the factors associated with the anastomotic leakage after anterior resection in rectal cancer. Methods: From January 2014 to January 2017 471 patients underwent Dixon procedure for rectal cancer in The Affiliated Hospital of Qingdao University. The data of those patients was collected and reviewed retrospectively. Inclusion criteria included: 1) rectal cancer confirmed by preoperative electron colonoscopy; 2) the standard of total mesorectal excision followed by the surgeon during the surgery; and 3) elective surgery. Exclusion criteria included multi-primary rectal cancer, secondary surgery for tumor recurrence, palliative surgery, Miles procedure, Hartmann procedure, hormone drugs used, presence of rheumatic and immune diseases, and distant metastasis of rectal cancer. The variables, including demograpic characteristics, ASA score, diabetes mellitus, preoperative radiochemotherapy, histopathologic grade, pathological T stage, laparoscopic or open surgery, distance of the tumor from the anal verge ≤5 cm, were analyzed to identify the risk factors for anastomotic leakage. Results: Of 471 patients, 285 and 186 were men and women, respectively, with a mean age of 61 years (range, 31-92) years. Symptomatic clinically anastomotic leakage occurred in 31 patients (6.6%, 31/471) after Dixon procedure for rectal cancer. On univariate analysis, the occurrence of anastomotic leakage was associated with diabetes (χ² = 10.972, P = 0.001) , serum albumin level < 35 g/L (χ² = 9.784, P = 0.002) , neoadjuvant chemoradiotherapy (χ² = 6.867, P = 0.009) , distance ≤5 cm between the tumor and anal edge (χ² = 5.993, P = 0.014) , preventive colostomy (χ² = 5.630, P = 0.018) , and the use of double-perfusion cannula for abdominal flushing (χ² = 4.232, P = 0.040) . Multivariate analysis revealed that diabetes (OR = 3.632, 95%CI: 1.620-8.145, P = 0.002) , neoadjuvant chemoradiotherapy (OR = 3.177, 95%CI: 1.283-7.867, P = 0.012) and distance ≤5 cm between the tumor and anal edge (OR = 2.444, 95%CI: 1.172 - 5.059, P = 0.017) were independent risk factors for anastomotic leakage, while preventive colostomy (OR = 0.138, 95%CI: 0.056 - 0.345, P = 0.000) and the use of double-perfusion cannula for abdominal flushing (OR = 0.223, 95%CI: 0.086 - 0.575, P = 0.002) were independent protective factors for anastomotic leakage. Conclusions For patients with rectal cancer with diabetes, undergoing neoadjuvant chemoradiotherapy, or distance ≤5 cm between the tumor and anal edge, anastomotic leakage after anterior resection of rectal cancer must be paid attention. When necessary, preventive colostomy or use of double-perfusion cannula for abdominal flushing should be considered.

Objective:To investigate the clinical efficacy of laparoscopic sleeve gastrectomy (LSG) for obesity complicated with obstructive sleep apnea syndrome (OSAS).Methods:The retrospective and descriptive study was conducted. The clinical data of 74 patients with obesity complicated with OSAS who were admitted to People's Hospital of Xinjiang Uygur Autonomous Region from January 2017 to June 2018 were collected. There were 40 males and 34 females, aged (39±10)years, with a range from 20 to 56 years. Observation indicators: (1) surgical and postoperative situations; (2) follow-up; (3) correlation analysis between obesity indicators and OSAS indicators; (4) analysis of factors influencing the postoperative efficacy of OSAS. Follow-up using hospitalization examination was conducted to detect the incidence of complications and the improvement of obesity and OSAS indicators after patients discharge. The follow-up was up to June 2019. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages. Repeated measurement data was analyzed using the mixed-effects model. Correlation analysis was conducted using the Pearson correlation coefficients. Multivariate analysis was conducted using the COX proportional risk regression model. Results:(1) Surgical and postoperative situations: 74 patients underwent LSG successfully, without conversion to open surgery, including 12 cases undergoing LSG combined with laparoscopic cholecystectomy and 9 cases undergoing LSG combined with esophageal hiatal hernia repair. The operation time and volume of intraoperative blood loss of 74 patients were (88±22)minutes and (57±25)mL. There was no severe postoperative complications and perioperative mortality. The duration of postoperative hospital stay of 74 patients were 5 days (range, 3-8 days). (2) Follow-up: among 74 patients, 71 were followed up at 1 month, 68 were followed up at 3 months, 64 were followed up at 6 months and 61 were followed up at 12 months after operation, respectively. The body mass, body mass index (BMI), abdominal circumference, chest circumference, neck circumference, apnea hypopnea index (AHI), average oxyhemoglobin saturation (ASaO 2), lowest oxygen saturation, epworth sleepiness scale score, excess weight loss rate of the 71 patients who were followed up at 1 month after operation were (108±16)kg, (38±5)kg/m 2, (121±14)cm, (122±13)cm, (41.3±2.5)cm, (25±15)times/hour, 88.1%±3.8%, 70.0%±9.3%, 17.8±2.3, 30%±8%, respectively. The above indicators of the 68 patients who were followed up at 3 month after operation were (96±14)kg, (33±5)kg/m 2, (113±13)cm, (120±12)cm, (39.7±2.3)cm, (17±11)times/hour, 90.2%±3.1%, 78.5%±7.1%, 15.0±2.2, 52%±13%, respectively. The above indicators of the 64 patients who were followed up at 6 month after operation were (88±11)kg, (31±4)kg/m 2, (105±11)cm, (113±11)cm, (37.5±1.7)cm, (10±7)times/hour, 92.4%±2.2%, 84.2%±3.5%, 13.6±1.7, 63%±14%, respectively. The above indicators of the 61 patients who were followed up at 12 month after operation were (80±8)kg, (28±3)kg/m 2, (97±8)cm, (108±10)cm, (36.5±1.4)cm, (6±4)times/hour, 93.7%±1.4%, 88.0%±3.1%, 9.2±1.5, 75%±16%, respectively. There were significant differences in the body mass, BMI, abdominal circumference, chest circumference, neck circumference, AHI, ASaO 2, lowest oxygen saturation, epworth sleepiness scale score of patients before and after operation ( F=109.855, 108.632, 90.565, 27.846, 96.353, 49.969, 48.561, 115.938, 257.762, P<0.05). There were 39 cases with AHI<5 times/hour in the 61 patients who were followed up at 12 month after operation, and the clinical complete response rate of OSAS was 63.93%(39/61). (3) Correlation analysis between obesity indicators and OSAS indicators: results of the Pearson correlation analysis showed that the AHI was positively correlated with the body mass and BMI ( r=0.267, 0.317, P<0.05) and negatively correlated with the ASaO 2 and lowest oxygen saturation ( r=-0.525, -0.551, P<0.05), and there was no correlation between AHI and neck circumference ( P>0.05) in the 74 patients before operation. The lowest oxygen saturation was negatively correlated with the body mass and BMI ( r=-0.330, -0.400, P<0.05), and there was no correlation between lowest oxygen saturation and neck circumference ( P>0.05) in the 74 patients before operation. The AHI was negatively correlated with the ASaO 2 and lowest oxygen saturation ( r=-0.406, -0.373, P<0.05), and there was no correlation between AHI and the body mass, BMI or neck circumference ( P>0.05) in the 61 patients who were followed up at 12 month after operation. There was no correlation between lowest oxygen saturation and the body mass, BMI or neck circumference ( P>0.05) in the 61 patients who were followed up at 12 month after operation. (4) Analysis of factors influencing the postoperative efficacy of OSAS: results of the multivariate analysis showed that preoperative AHI was an independent influence factor for postoperative efficacy of OSAS ( hazard ratio=1.039, 95% confidence interval: 1.016-1.063, P<0.05). Conclusion:LSG can effectively reduce the body mass and improve OSAS of patients with obesity complicated with OSAS in the short term.
