ABSTRACT
Objective:To study the clinical application of jejunal feeding tube (J-tube) for early enteral nutrition after surgical treatment of upper digestive tract malformation in newborns.Methods:From January 2019 to December 2021, newborns with upper digestive tract malformation received stage Ⅰ small bowel resection and anastomosis in our hospital were enrolled in this prospective randomized controlled study. According to different types of postoperative nutritional support, these patients were randomly assigned into J-tube group and control group using block randomization method. The J-tube group were given enteral nutrition vis J-tube within 48-72 h after surgery and the control group were given oral feeding after the recovery of gastrointestinal function. Calories and proteins intake, growth indicators, duration of hospital stay and parenteral nutrition, time needed for full oral feeding and complications were compared between the two groups.Results:A total of 24 patients were in J-tube group and 28 in controlled group. No significant differences existed on the general status between the two groups ( P>0.05). The average daily intake of calories and proteins in j-tube group in the first week after surgery were significantly higher than control group [(108.7±8.3) kcal/(kg·d) vs. (97.9±7.0) kcal/(kg·d), (3.4±0.3) g/(kg·d) vs. (3.1±0.2) g/(kg·d)] ( P<0.05). No significant differences existed in the average daily intake of calories and proteins during the second postoperative week between the two groups ( P>0.05). Compared with control group,J-tube group showed increased growth velocity in head circumference and weight over time ( P<0.05), while the trend over time in length growth was not significant ( P>0.05). No significant differences existed in the duration of hospital stay and parenteral nutrition, time needed for full oral feeding and complications between the two groups ( P>0.05). Conclusions:Enteral nutrition via J-tube 48-72 h after surgery is safe and feasible in the postoperative nutritional management of newborns with upper digestive tract malformation. This strategy may promote physical growth after surgery without increasing the incidences of complications.
ABSTRACT
Objective:To systematically review and evaluate the effect of intraoperative regional cerebral oxygen saturation (rSO 2) monitoring on perioperative neurocognitive disorders (PNDs) in elderly patients undergoing non-cardiac surgery. Methods:China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Database, China Science and Technology Journal Database, PubMed, Cochrane Library, Embase and Web of Science databases were searched from inception to October 2022 for randomized controlled trials involving the effects of intraoperative rSO 2 monitoring on PND in elderly patients underwent non-cardiac surgery. The primary outcome measure was the incidence of PND (1-7 days after surgery), and secondary outcome measures were intraoperative minimum rSO 2 (rSO 2min), intraoperative mean rSO 2 (rSO 2mean), maximum percentage of decrease (rSO 2% max) in rSO 2 from baseline (rSO 2baseline), and the Montreal Cognitive Assessment Scale was used to evaluate the quality of references that met the inclusion criteria, and data were extracted for meta-analysis using RevMan5.4 software. Results:Thirteen randomized controlled trials were enrolled, involving 1 134 patients with 557 patients in experimental group (anesthesia under rSO 2 monitoring) and 577 patients in control group. The results of meta-analysis showed that the incidence of PND was significantly lower in experimental group than in control group ( RR=0.32, 95% confidence interval [ CI] 0.25-0.41, P<0.001), the intraoperative rSO 2min was significantly higher in experimental group than in control group ( MD=7.46, 95% CI 5.05-9.86, P<0.001), and the intraoperative rSO 2mean was significantly higher in experimental group than in control group ( MD=5.49, 95% CI 3.97-7.02, P<0.001), the intraoperative rSO 2% max was significantly lower in experimental group than in control group ( MD=-6.55, 95% CI-9.03--4.07, P<0.001), and the postoperative Montreal Cognitive Assessment Scale score was significantly higher in experimental group than in control group ( MD=1.37, 95% CI 0.74-1.99, P<0.001). Conclusions:Intraoperative application of rSO 2 monitoring can reduce the occurrence of PND in elderly patients undergoing non-cardiac surgery.
ABSTRACT
Objective:To investigate the expression level of plasma miR-320c in patients with osteoarthritis(OA), and explore the clinical significance and the role in pathogenesis of OA.Methods:The clinical data and peripheral blood of 30 patients with OA, 30 patients with connective tissue diseases and 30 healthy control individuals were collected.The levels of plasma miR-320c were detected byfluorescentquantitative reverse transcription PCR(qRT-PCR). Correlation analysis was used to explore the correlation of plasma miR-320c level with knee X-ray data and VAS pain score in OA patients.Finally the miR-320c mimic, the miR-320c inhibitor, and the control material were transfected to the chondrocyte HC-a.The proliferative capacity of HC-a chondrocytes was examined at different time points as determined by the CCK-8 assay.Results:The expression level of plasma miR-320c was significantly higher in OA group(3.26±0.55)than that in the connective tissue diseases group(1.62±0.50)and in healthy control group(1.21±0.66)( F=107.66, P<0.001). Plasma miR-320c expression was positively correlated with radiographic grade( r=0.830, P<0.001), and had no correlation with VAS pain score in OA group( P>0.05). Through repeated measurement variance analysis, the time effect, the group effect and the interaction effect between group and time showed statistically significant differences in chondrocyte proliferation between NC mimic group and miR-320c mimic group( Ftime=5256.767, Fgroup=1947.436, Ftime×group=114.314, all P<0.001). The level of proliferation was significantly reduced.Apoptosis rate of chondrocytes was significantly increased in the group transfected with miR-320c( t=7.85, P<0.01). Conclusions:The expression level of plasma miR-320c is significantly higher in osteoarthritis patients and associated with knee radiographic severity grade.Furthermore, over-expression of miR-320c could suppress the proliferation of chondrocytes.Plasma miR-320c might be potential bio-marker for osteoarthritis knee severity assessment, and involves in regulating chondrocyte growth in the pathogenesis of osteoarthritis.

Al 18F-NOTA-FAPI-04 PET/CT imaging was performed in normal BALB/c mice ( n=3) and 4T1 breast cancer models ( n=3) to determine its biodistribution. Then Al 18F-NOTA-FAPI-04 and 18F-FDG PET/CT imaging were performed in a hepatocellular carcinoma patient (male, 51 years old). Results:The synthesis time of Al 18F-NOTA-FAPI-04 was about 35 min, and the radiochemical yield was (25.2±1.9)% (attenuation correction, n=3). The product was colorless transparent solution with pH value of 7.0-7.5, and the specific activity was (46.11±3.07) GBq/μmol (attenuation correction, n=3). The radiochemical purity was above 99.0% and was still above 98.0% at room temperature after 6 h. PET/CT imaging in mice showed that physiological uptake of Al 18F-NOTA-FAPI-04 was mainly in biliary system and bladder, and Al 18F-NOTA-FAPI-04 highly concentrated in tumor xenografts. PET/CT imaging in the patient showed that Al 18F-NOTA-FAPI-04 obtained high tumor background ratio (TBR) values of 4.1, 8.9, 5.4, 4.8, 2.2 in parasternal lymph nodes, anterior diaphragmatic lymph nodes, hilar lymph nodes, pancreaticoduodenal ligament lymph nodes, abdominal aortic lymph nodes, respectively, while TBR values were 1.0, 2.8, 5.0, 2.1, 1.1 by 18F-FDG. Conclusions:Al 18F-NOTA-FAPI-04 can be synthesized with short time, high radiochemical yield and good stability using All-in-one module. Al 18F-NOTA-FAPI-04 PET/CT imaging has high contrast and excellent diagnostic efficacy on tumors.
ABSTRACT
Objective: To investigate the molecular pathogenesis and clinical features of unrelated 12 patients with inherited coagulation protein C (PC) deficiency in Chinese population. Methods: The PC activity (PC:A) and PC antigen (PC:Ag) were detected by chromogenic substrate and enzyme linked immunosorbent assay, respectively. The nine exons and flanking sequences of the protein C (PROC) gene were amplified by polymerase chain reaction with direct sequencing, and the suspected mutations were validated by reverse sequencing (clone sequencing for deletion mutations) . Results: The PC:A of the 12 probands decreased significantly, ranging from 18% to 55%, and the PC:Ag of the 10 probands decreased significantly. Eleven mutations were found, out of which four mutations [c.383G>A (p.Gly128Asp) , c.997G>A (p.Ala291Thr) , c.1318C>T (p.Arg398Cys) , and c.532G>C (p.Leu278Pro) ] were discovered for the first time. Six mutations were in the serine protease domain, four mutations were located in epidermal growth factor (EGF) -like domains, and one mutation was located in activation peptide. There were two deletion mutations (p.Met364Trp fsX15 and p.Lys192del) , and the rest were missense mutations. Mutations p.Phe181Val and p.Arg189Trp were identified in three unrelated families. All mutations may be inherited, and consanguineous marriages were reported in two families. Among the probands, nine cases had venous thrombosis, two cases had poor pregnancy manifestations, and one case had purpura. Conclusion: Patients with PC deficiency caused by PROC gene defects are prone to venous thrombosis, especially when there are other thrombotic factors present at the same time.

On December 22, 2017, a 35-year-old male hemophilia A patient with a secondary chronic refractory wound after left knee joint surgery was transferred from the Department of Hematology of Maoming People's Hospital to the Department of Burns and Plastic Surgery in the same hospital. The physical examination revealed that the patient's left knee joint was swollen, with a full-thickness skin defect wound of 4 cm×4 cm on the lateral side of the joint and a large number of dark red blood clots at the bottom of the wound. The wound bleeding was controlled by intravenous infusion of plasma, cryoprecipitate, and human coagulation factor Ⅷ. After con- ventional debridement and dressing changes until the wound infection was controlled and necrotic tissue was removed, a subcutaneous cavity wound of 2 cm×2 cm in area and 3 cm in depth remained in the left knee joint and was difficult to heal. Nineteen days after transfer, the patient received autologous platelet-rich plasma (PRP) treatment, and 32 days after PRP treatment, the wound in left knee joint was healed with epithelialization. This case suggests that autologous PRP therapy would be a good option for hemophilia complicated chronic refractory wounds when they could not be repaired by surgery.

Polymerase chain reaction (PCR) was used to amplify the 6 and 7 exons as well as their adjacent intron region of ABO gene. The patients and their relatives′ ABO blood group and subgroup were analyzed and identified through the comparison with serological phenotype database of ABO blood group. The products of PCR were sequenced directly, and the gene mutation was identified through the comparison with the Blood Group Antigen Gene Mutation Database. 【Results】 Whether micro-column gel cards or manual tube test, the forward and reverse tests of serological grouping were not supported by each other on the five patients′ ABO blood grouping. The forward tests of patients No.1~3 showed AwB phenotype and the reverse tests showed B group. No.4 patient was the forward ABw phenotype and the reverse A group, and No.5 patient was the forward normal AB phenotype and the reverse B group, respectively. All of 5 patients′ Rh C/D/E blood grouping showed clearly; the IDT test and antibody screening result of patient No.1 was positive, while the antibody screening result of patient No.4 was negative. 【Conclusion】 The blood group serological characterization of patient No.1~3 met B(A) blood group, and patient No.4~5 met CisAB blood group. These tests can make a preliminary diagnosis of blood group phenotype, which are verified correctly via blood group genotype.
ABSTRACT
OBJECTIVE@#To explore the effect of scalp acupuncture combined with suspension training on balance ability and motor function in stroke patients with balance dysfunction.@*METHODS@#A total of 105 stroke patients with balance dysfunction were randomly divided into a combined group (35 cases, 2 cases dropped off), a scalp acupuncture group (35 cases, 3 cases dropped off) and a suspension training group (35 cases, 2 cases dropped off). The scalp acupuncture group was treated with scalp acupuncture at bilateral suboccipital lateral line, parietal midline, upper 1/5 line of anterior oblique line of parietal and temporal and line 1 of the parietal lateral line on the opposite side of hemiplegia. The suspension training group was treated with suspension training. The combined group was treated with suspension training at the same time of scalp acupuncture. All the treatment was given once a day, 30 min each time, 5 days a week, for a total of 6 weeks. The Berg balance scale (BBS) score, balance tester and Fugl-Meyer assessment (FMA) score were used to evaluate the motor function and balance ability before treatment, 3 and 6 weeks into treatment. The clinical efficacy was evaluated in the 3 groups.@*RESULTS@#The scores of BBS and FMA in each group at 3 and 6 weeks into treatment were higher than those before treatment (@*CONCLUSION@#Scalp acupuncture combined with suspension training could improve the balance ability and motor function in stroke patients with balance dysfunction, and the curative effect is better than simple scalp acupuncture and simple suspension training.

Purpose@#This study assessed the correlation between Epstein-Barr virus (EBV) biomarkers and the eighth American Joint Committee on Cancer staging system and the prognostic values of IgG antibodies against replication and transcription activator (Rta-IgG), IgA antibodies against Epstein-Barr nuclear antigen 1, and BamH1 Z transactivator (Zta-IgA) in locoregionally advanced nasopharyngeal carcinoma (NPC) patients. @*Materials and Methods@#Serum EBV antibody levels were measured by enzyme-linked immunosorbent assay in 435 newly diagnosed stage III-IVA NPC patients administered intensity-modulated radiation therapy±chemotherapy. The primary endpoint was progression-free survival (PFS). @*Results@#Rta-IgG and Zta-IgA levels were positively correlated with the N category and clinical stage. Patients with high Rta-IgG levels (> 29.07 U/mL) showed a significantly inferior prognosis as indicated by PFS (77% vs. 89.8%, p=0.004), distant metastasis–free survival (DMFS) (88.3% vs. 95.8%, p=0.021), and local recurrence-free survival (LRFS) (91.2% vs. 98.3%, p=0.009). High Rta-IgG levels were also significantly associated with inferior PFS and LRFS in multivariable analyses. In the low-level EBV DNA group (≤ 1,500 copies/mL), patients with high Rta-IgG levels had significantly inferior PFS and DMFS (both p < 0.05). However, in the high-level EBV DNA group, Rta-IgG levels were not significantly associated with PFS, DMFS, and LRFS. In the advanced T category (T3-4) subgroup, high Rta-IgG levels were also significantly associated with inferior PFS, DMFS, and LRFS (both p < 0.05). @*Conclusion@#Rta-IgG and Zta-IgA levels were strongly correlated with the TNM classification. Rta-IgG level was a negative prognostic factor in locoregionally advanced NPC patients, especially those with advanced T category or low EBV DNA level.
ABSTRACT
Objective:To discuss the effect of modified ultrafiltration combined with sequential infusion of blood products, such as platelets and cryoprecipitation, on perioperative coagulation function in neonates undergoing cardiovascular surgery under extracorporeal circulation.Methods:A retrospective analysis was performed on 83 neonates who underwent cardiovascular surgery from January 2017 to December 2019. They were divided into the control group (conventional ultrafiltration, 51 cases) and the treatment group (modified ultrafiltration + sequential infusion of blood products, 32 cases).Results:The age of treatment group was significantly younger than that of the control group ( P<0.05). The extracorporeal circulation time of the treatment group was significantly longer than that of the control group. Compared with the preoperative data, post-APTT, post-PT and post-INR were increased significantly in the control group, platelet count and FIB were decreased significantly ( P<0.01), while there was no significant difference in the treatment group. Compared with the treatment groups, post-APTT, post-PT and post-INR were significantly increased in the control group, and postoperative platelet count and FIB were significantly decreased ( P<0.05). The drainage of control group was significantly higher than that of the treatment group at 12 h and 24 h after surgery ( P<0.01). Conclusion:The application of modified ultrafiltration combined with sequential infusion of blood products can significantly improve perioperative coagulation and reduce mediastinal bleeding in neonatal after cardiovascular surgery.
ABSTRACT
Objective:To explore the effects of Shenwei Ningyu pills （SNP）， a new Chinese medicine for depression， on the immunoinflammatory response mediated by Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88） signaling pathway in the hippocampus of rats exposed to chronic restraint stress （CRS）. Method:Forty-four male Sprague Dawley rats were randomly enrolled into a normal group， a model group， an escitalopram group， and an SNP group. Except for the rats in the normal group， all rats were exposed to CRS and isolated rearing for 21 days continuously. Rats in the escitalopram group and the SNP group were administered with escitalopram （30 mg·kg<sup>-1</sup>） and SNP （18 mg·kg<sup>-1</sup>） one hour prior to CRS， respectively. The changes in body weight， sucrose preference index， horizontal movement scores， and vertical movement scores were observed by body weight assessment， sucrose preference test， and open field test. The expression of hippocampal TLR4 and MyD88 was detected by Western blot. The content of serum interleukin-1<italic>β</italic> （IL-1<italic>β</italic>）， IL-10， and tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>） was detected by enzyme-linked immunosorbent assay （ELISA）. Result:The results of the behavioral assessment showed that there was no significant difference in the changes of behavioral baselines among the groups before intervention. However， significant differences were found among the groups following different interventions. The body weight， sugar preference index， horizontal movement score， and vertical movement score of rats in the model group decreased after CRS for 21 days as compared with those in the normal group （<italic>P</italic><0.01）. The above indicators in the SNP<italic> </italic>group and the escitalopram group were higher than those in the model group （<italic>P</italic><0.01）， which indicated that SNP<italic> </italic>exerted an obvious antidepressant effect. The results of Western blot and ELISA showed that compared with the normal group， the model group showed elevated levels of hippocampal TLR4 and MyD88 and serum IL-1<italic>β</italic> and TNF-<italic>α </italic>（<italic>P</italic>˂0.01） and dwindled serum IL-10 （<italic>P</italic>˂0.01）， while SNP<italic> </italic>and escitalopram reversed the conditions in the model group （<italic>P</italic>˂0.01） except for TNF-<italic>α</italic>. Conclusion:The present study indicated that the antidepressant effect of SNP was presumedly achieved by inhibiting the immunoinflammatory response mediated by the TLR4/Myd88 signaling pathway in CRS rats.
ABSTRACT
Objective To investigate the effectiveness and cost of 50% and 80% wettable powder of niclosamide ethanolamine salt (NESWP) and 26% metaldehyde and niclosamide suspension concentrate (MNSC) in hilly schistosomiasis-endemic regions, so as to provide insights into the selection of chemical molluscicides in hilly regions. Methods In September 2020, a wasteland in Guanshanqiao Village, Yanrui Township, Yushan County of Jiangxi Province was selected as the experimental region, which was sectioned into five blocks and defined as four experimental groups (A1, A2, B, C) and a blank control group (D). 80% NESWP were given at doses of 1 g/m2 and 1.5 g/m2 in groups A1 and A2 using the spraying method, 50% NESWP was given at a dose of 2 g/m2 in Group B using the spraying method, and 26% MNSC was at a dose of 4 g/m2 in Group C using the spraying method, while no chemical treatment was given in Group D. Snail survey was performed using a systematic sampling method before chemical treatment and 1, 3, 7 d and 15 d post-treatment to examine the molluscicidal effect, and all molluscicidal costs were estimated to calculate the cost of chemical treatment per 1 m2 and the cost of the reduction in the mean density of living snails per 1%. Results The highest mortality of snails was 78.95% and the lowest density of living snails was 0.2388 snails/0.1 m2 in the experimental groups within 7 d of chemical treatment, and the highest mortality of snails was 94.74% and the lowest density of living snails was 0.058 0 snails/0.1 m2 7 d post-treatment. There were no significant differences in the snail mortality among the A1, A2, B and C groups 1 (χ2 = 2.250, P > 0.05), 3 (χ2 = 1.779, P > 0.05) or 15 d post-treatment (χ2 = 2.286, P > 0.05), while a significant difference was detected in the snail mortality among the four groups 7 d post-treatment (χ2 = 7.990, P = 0.046). In addition, there were no significant differences in the snail mortality between A1 and A2 groups 1 (χ2 = 0.724, P > 0.05), 3 (χ2 = 0.584, P > 0.05), 7 (χ2 = 0.400, P > 0.05) or 15 d post-treatment (χ2 = 0.251, P > 0.05). The costs of chemical treatment per 1 m2 were 0.58, 0.60, 0.64 Yuan and 0.73 Yuan in groups A1, A2, B and C, and the costs of the mean density of living snail per 1% reduction were 19.29, 20.44, 21.68 Yuan and 23.53 Yuan in groups A1, A2, B and C, respectively. Conclusion 80% NESWP shows a high molluscicidal efficacy and low cost in hilly schistosomiasis-endemic regions.
ABSTRACT
Objective:To develop the screening checklist of brief interview for autism disorder suitable for Chinese children and evaluate its reliability and validity.Methods:Based on existed research results and diagnostic criteria for autism spectrum disorder of DSM-5, the screening checklist of brief interview for autism spectrum disorder(SCAD) was developed. A sample of 238 children were selected for investigation and 28 of them were retested for test-retest reliability with 2-4 weeks interval. Cronbach's α coefficient, split-half correlation coefficient, test-retest reliability, and evaluator consistency were used to test the reliability of the scale. Content validity, construct validity and empirical validity were used to test the validity of the scale.All statistical analysis were conducted by SPSS 22.0 and AMOS 17.0.Results:The SCAD contains two components and six dimensions, with a total of 25 items. The Cronbach's α coefficient was 0.936 for the total scale and were 0.938, 0.771 for the two components. The split-half coefficient for the total scale and the two components were 0.962, 0.938 and 0.794. The test-retest reliability for the total scale and the two components were 0.806, 0.795 and 0.766. The Kendall coefficient for the total scale and the two components were 0.968, 0.982 and 0.950. The SCAD item-level content validity index (I-CVI) ranged from 0.66 to 0.98 and the Kappa value ranged from 0.66 to 0.98. The scale-level content validity S-CVI/UA and S-CVI/Ave were 0.89 and 0.94. The correlations between SCAD and calibration tests such as ABC, CARS and M-CHAT were 0.54, 0.53 and 0.87, and the correlation coefficients with the M-CHAT-R/F between the two components were 0.87 and 0.76 respectively (both P<0.01). The result of CFA demonstrated that the model fitted the data with well construct validity(χ 2/ df=0.910, RMR=0.049, AGFI=0.974, RMSEA=0.010, PNFI=0.530, PCFI=0.533, NFI=0.994, RFI=0.988, CFI=1.000). The correlation coefficient of the two components was 0.88 and that with the total scale were 0.97 and 0.90, each dimensions with the total scale ranged from 0.72 to 0.93. Conclusion:The SCAD has a good reliability and validity, and it can be used as a clinical screening tool for children with autism spectrum disorder.

ABSTRACT
Objective:To study the clinical characteristics and compliance of early-onset gout patients by case-control analysis.Methods:A total of 111 early-onset patients (onset age ≤35 years old) were included as Group A, and 111 non-early-onset patients (onset age >35 years old) with matched disease durationwere included as Group B. The differences ofclinical characteristics, causes of acute gout attack, dairy diet habits, compliance, and misunderstanding of the disease were compared.Results:Compared with the non-early-onsetgoutpatients, the early-onset patients had a higher proportion of obesity (63 cases vs 28 cases), family history (36 cases vs 20 cases) and tophus (39 cases vs 23 cases) and higher level of VAS scores (8.5±1.3 vs 7.6±1.7; χ2=22.988, P<0.01; χ2=5.749, P=0.016; χ2=5.729, P=0.017; t=4.639, P<0.01), lowerproportionof the first metatarsophalangeal joint involvement as the initial joint involvement (45.9%, 51 cases vs 59.4%, 66 cases; χ2=4.066, P=0.044), higher proportion of the ankle involvement as the initial joint involvement (34.2%, 38 cases vs 21.6%, 24 cases; χ2=4.386, P=0.036), higher proportion of alcohol drinkers and high fructose drinkers, which was more likely to relate to alcohol intake, strenuous exercise and high fructose intakeas trigger of the flare ( χ2=6.513, P=0.011; χ2=7.126, P=0.008; χ2=1.978, P=0.160), while the proportion of regular exercisers and on diet in the family was lower ( χ2=22.887, P<0.01; t=-4.917, P<0.01). The proportion of poor diet and medication compliance in Group A was higher than that in Group B(57.7%, 64 cases vs 38.7%, 43 cases; χ2=5.207, P=0.022; χ2=5.867, P=0.015). As for the reason for poor treatment compliance, early-onset gout patients were more worry about the side-effects of drugs than non-early onset patients ( χ2=4.190, P=0.041). There was no significant difference between the two groups in the main misunderstanding of gout. Conclusion:Although early onset gout patients are young, their condition is more serious, and compliance is poorer, this group of patients should be highly valued in clinical diagnosis and treatment.
ABSTRACT
Objective: To assess the predictive value of metabolic parameters with different maximum standard intake value (SUVmax) threshold segmentations calculated from 18F-FDG PET/CT before concurrent chemoradiotherapy (CCRT) of cervical cancer. Methods: Totally 45 patients underwent 18F-FDG PET/CT before CCRT, and SUVmax, maximum standard intake value (MTV) and metabolic tumor volume (TLG) were recorded. MTV and TLG were automatically segmented using different percentage SUVmax threshold segmentations (10%-85%, increased by 5%). Receiver operating characteristic (ROC) curve analysis was performed in order to obtain the cut-off values of MTV and TLG. Kaplan-Meier method was used for survival analysis. Results: SUVmax, MTV10%, MTV75%-MTV85% and TLG75%-TLG85% were not significantly different (all P>0.05), whereas significant differences of MTV15%-MTV70% and TLG10%-TLG70%were found between 2 groups (all P<0.05). 40%SUVmax had the strongest prediction capability for prognosis. Based on ROC curve analysis, the cut-off value of MTV40% was 21.09, with sensitivity of 78.60%, specificity of 87.10% and AUC of 0.823, while the cut-off value of TLG40% was 136.71, with sensitivity of 78.60%, specificity of 77.40% and AUC of 0.788. Conclusion: MTV40% and TLG40% calculated from 18F-FDG PET/CT can be taken as prognostic indicators for cervical cancer after CCRT.
ABSTRACT
Hypophosphatemia is a common metabolism disease in humans. Fibroblast growth factor 23 (FGF23) inhibits phosphate reabsorption by targeting on the renal tubules. FGF23C-tail contains 73 amino acids from C-terminus of FGF23, serves as an inhibitor of FGF23, and can increase phosphate reabsorption. Therefore, FGF23C-tail is an important drug for hypophosphatemia. In this paper, we constructed a fusion protein of FGF23C-tail with HSA, and investigated the expression of the fusion protein in the Pichia pastoris system. The recombinant gene was constructed by fusion PCR. A high-yield strain was selected by G418 resistance and fermentation yield, and the expression yield was 43.7 mg·L-1 in flask. In 5 L fermenters, the highest expression yield could reach 265.6 mg·L-1. FGF23C-tail-HSA could be used as an inhibitor for FGF23, and could significantly increase blood phosphorus levels in rats. The procedures for care and use of animals were approved by the Ethics Committee of YiChun University. This paper provided a basis research for further studying physiological activity of FGF23C-tail-HSA.
ABSTRACT
OBJECTIVE@#To investigate the effects of berberine on learning and memory ability in vascular cognitive impairment rats.@*METHODS@#Sixty-eight Wistar rats were randomly divided into control group (n=10), sham operated group (n=10) and the modeling group of vascular cognitive impairment rat (n=48), then the rats in modeling group were randomly divided into four groups (n=10): vehicle group, berberine low dose group (20 mg/kg), medium dose group (40 mg/kg) and high dose group (60 mg/kg). Bilateral common carotid arteries were occluded in rats to establish vascular cognitive impairment (VCI) model. Different doses of berberine were intraperitoneally injected into the treatment group and normal saline was intraperitoneally injected into the other groups once a day for a total of 34 days. After 28 days of administration, Morris water maze was used to test the learning and memory ability of rats. After the water maze experiment, the levels of superoxide dismutase (SOD) activity, glutathione (GSH), malondialdehyde (MDA), tumor necrosis factor alpha(TNF-α), interleukin-1 beta (IL-1β), 5-hydroxytryptamine (5-HT) and monoamine oxidase (MAO) in the forebrain cortex were detected.@*RESULTS@#Compared to sham group, the escape latency in VCI group was significantly extended (P＜0.01) and the times of passing through the platform were decreased remarkably (P＜0.01). The levels of SOD, GSH and 5-HT in the hippocampus or anterior cortex were decreased significantly (P＜0.01), while the contents of MDA, TNF-α, IL-1β and MAO were increased remarkably (P＜0.01). Compared with VCI group, the escape latency in berberine-treated groups was shortened significantly (P＜0.01, P＜0.05) and the times of passing through the platform were increased remarkably (P＜0.01, P＜0.05), the levels of SOD, GSH and 5-HT were increased significantly (P＜0.01), while the contents of TNF-α, IL-1β and MAO were decreased remarkably (P＜0.01).@*CONCLUSION@#Berberine could significantly improve the spatial learning and memory abilities of rats with vascular cognitive impairment. The mechanism may be related to the effects of berberine on the hippocampal antioxidant stress, anti-inflammatory response and the monoamine neurotransmitter system in the forebrain cortex. Berberine 60 mg/kg dose group had better effect.

Objective@#To evaluate the clinical application of single-arm external stent combined with free flap in the treatment of forearm fractures of Gustilo type Ⅲ.@*Methods@#A retrospective study was conducted of the 16 patients who had been treated at Repair and Reconstruction Center, Traditional Chinese Medicine Hospital Affiliated to Southwest Medical University from September 2015 to January 2018 for open forearm fractures combined with soft tissue defects with single-arm external stent combined with free flap. They were 11 men and 5 women, aged from 18 to 64 years (average, 41.6 years). By the Gustilo classification, 9 cases were type ⅢB and 7 type ⅢC. The area of soft tissue defects at the upper arm and hand ranged from 7.5 cm×5.5 cm to 16.5 cm × 11.0 cm. Emergency debridement was performed at the primary stage. After repair of major blood vessels, nerves and tendons, the reduced fractures were fixated with a single-arm external stent. The soft tissue defects were repaired with free flaps at the secondary stage. Nine cases were repaired with a free anterolateral perforating branch flap and 7 with a free ilioinguinal flap. The single-arm external stent became the ultimate fixation mode in 5 cases but was changed into plate fixation after survival of the flaps in the other 11 cases. Complications were recorded postoperatively. At the last follow-up, the upper limb function was evaluated according to the tentative criteria for evaluation of the upper limb function proposed by the Hand Surgery Society of Chinese Medical Association.@*Results@#Of all the free flaps, 14 survived smoothly but 2 anterolateral ones survived only after the venous crisis appearing at 24 h after operation was relieved by exploration. The 16 patients were followed up for 9 to 18 months (average, 13.5 months). The fractures united well with fine alignment of the fracture ends and recovered force line. According to the Anderson criteria for forearm fractures, 10 cases were excellent, 4 good and 2 fair after operation. According to the tentative criteria for evaluation of the upper limb function proposed by the Hand Surgery Society of Chinese Medical Association, 11 cases were excellent and 5 good. No nail infection or nonunion occurred.@*Conclusion@#In the treatment of forearm fractures of Gustilo type Ⅲ, single-arm external stent plus free flap can effectively restore the force line of upper extremity, promote bone healing, allow reasonable timing for wound repair, reduce postoperative complications like infection and osteomyelitis and facilitate functional recovery of the affected extremity.
ABSTRACT
The loss of endothelial connective integrity and endothelial barrier dysfunction can lead to increased vascular injury, which is related to the activation of endothelial inflammasomes. There are evidences that low concentrations of aspirin can effectively prevent cardiovascular diseases. We hypothesized that low-dose aspirin could ameliorate endothelial injury by inhibiting the activation of NLRP3 inflammasomes and ultimately prevent cardiovascular diseases. Microvascular endothelial cells were stimulated by lipopolysaccharide (2 μg/mL) and administrated by 0.1-2 mmol/L aspirin. The wild type mice were stimulated with LPS (100 μg/kg/day), and 1 h later treated with aspirin (12.5, 62.5, or 125 mg/kg/day) and dexamethasone (0.0182 mg/kg/day) for 7 days. Plasma and heart were harvested for measurement of ELISA and immunofluorescence analyses. We found that aspirin could inhibit NLRP3 inflammasome formation and activation in dose-dependent manner and has correlation between the NLRP3 inflammasome and the ROS/TXNIP pathway. We also found that low-concentration aspirin could inhibit the formation and activation of NLRP3 inflammasome and restore the expression of the endothelial tight junction protein zonula occludens-1/2 (ZO1/2). We assume that aspirin can ameliorate the endothelial layer dysfunction by suppressing the activation of NLRP3 inflammasome.
