Objective To discuss the effect under the arthroscope surgery and postoperative treat osteoarthritis with rehabilitation training.Methods 34 cases of osteoarthritis patients treated with the arthroscopy detectors were randomly divided into two groups:the therapeutic group(17 cases)and the control group(17 cases).The therapeutic group was treated with arthroscope surgery and rehabilitation training.The control group was treated only with arthroscopy surgery.All patients were followed up for 90 days.The postoperative pain,range of motion and joint function of the two groups were compared.Results The postoperative pain range of motion and joint function of the therapeutic group was significantly better than the control group(t=17.6,6.4,7.6,P＜0.05).Conclusion Rehabilitation training could relieve the postoperative pain and range of motion,improve the function of knee joint and increase the effect of clinical efficacy in the arthroscopic surgery of knee's under the osteoarthritis patients.

Objective To observe the effects of different compatibility ratios of Astragali Radix and Angelicae Sinensis Radix on vascular intimal hyperplasia; To ascertain the effective compatibility of Astragali Radix and Angelicae Sinensis Radix for antagonizing vascular intimal hyperplasia. Methods SD rats were divided into different groups by baseline geometric design method: Astragali Radix and Angelicae Sinensis Radix different compatibility ratios groups, Astragali Radix group, Angelicae Sinensis Radixgroup, positive medicinegroup and sham-operation group. A model of intimal hyperplasia of thoracoabdominal aorta was established by balloon catheter injury in vascular endothelium of rats. Then the thoracoabdominal aorta was taken out after gavage of Astragali Radix and Angelicae Sinensis Radix with different compatibility ratios for 14 days. Bloodletting was used to take thoracoabdominal aorta. Masson staining and Morphometric methods were used to analyze the intimal hyperplasia. Results IA, IT, HRIA and HRIT increased 14 day after intimal injury. Compared with the model group, IA, IT, HRIA and HRIT in Angelicae Sinensis Radix group, Astragali Radix and Angelicae Sinensis Radix 1:2 group, Astragali Radix and Angelicae Sinensis Radix 1:5 group, Astragali Radix and Angelicae Sinensis Radix 1:1 group and Astragali Radix and Angelicae Sinensis Radix 5:1 group were lower, and the effects of Astragali Radix and Angelicae Sinensis Radix 1:1 ratio were strongest. The effects on intimal hyperplasia in Astragali Radix group and Astragali Radix and Angelicae Sinensis 2:1 group had no significant differences compared with model group. Conclusion Astragali Radix and Angelicae Sinensis can inhibit vascular intimal hyperplasia in a certain compatibility ratios, and the effects of Astragali Radix and Angelicae Sinensis Radix 1:1 on intimal hyperplasia are the best.

Objective:To investigate the effect of melatonin (MEL) influence on lipopolysaccharide (LPS)-induced long-term anxiety-like behavior and activation of astrocytes in septic neonatal rats.Methods:Sprague-Dawley rats were randomly(random number) assigned to the control group, LPS group and LPS+MEL group. Sepsis model was intraperitoneally injected with LPS (1 mg/kg), and neonatal rats in the MEL group were administered with MEL (10 mg/kg) 30 min after LPS injection. At different time points after injection, rats in each group were divided into three subgroups: 3 d, 7 d and 28 d. The expression of GFAP and TNF-α in the corpus callosum was detected by immunofluorescence staining and Western blot. Open-field test was applied to observe anxiety-like behaviors. In vitro, cultured neonatal SD rat astrocytes were divided into the control group, LPS group, LPS+MEL group, and LPS+MEL+luzindole group. Immunofluorescence staining was used to observe the expression of GFAP and TNF-α. Expression of GFAP, TNF-α, p-NF-κBp65, NF-κBp65 protein in astrocytes were assessed by Western blot. RT-qPCR was used to investigate the mRNA expression of GDNF and BDNF. One-way ANOVA and two-way ANOVA were used for comparison of multiple groups of variables. A P<0.05 was considered statistically significant. Results:LPS reduced the duration of movement in the central area and distance in the central area/total distance in open-field test, while melatonin evidently reversed the LPS-induced anxiety-like behavior. Compared with the LPS group, the expressions of GFAP and TNF-α were significantly decreased in the corpus callosum at 3 d and 7 d in the MEL group ( P< 0.05). Compared with the LPS group, MEL could significantly decrease the expression of GFAP, TNF-α and p-NF-κBp65 in astrocytes ( P< 0.05), which could be blocked by Luzindole. In addition, compared with the LPS group, MEL pretreatment could reverse the down regulation of GDNF and BDNF induced by LPS ( P<0.05). Conclusions:MEL can relieve LPS-induced long-term anxiety-like behavior in septic neonatal rats. The mechanism may be related to the inhibition of astrocyte activation and inflammatory reaction through NF - κ B pathway.

Objective:To systematically evaluate the effect of hydrocortisone combined with vitamin C and vitamin B1 on the efficacy of patients with sepsis or septic shock.Methods:Databases including CNKI, Sino Med, VIP, Wanfang, PubMed, the Cochrane Library, and Embase were searched from inception to January 2021 for the randomized controlled trial (RCT) about hydrocortisone combined with vitamin C and vitamin B1 to treat sepsis or septic shock. The experimental group was given intravenous injection of hydrocortisone, vitamin B1 and vitamin C based on conventional treatment; the control group was given conventional treatment or placebo/hydrocortisone/hydrocortisone+vitamin B1 based on conventional treatment. Outcome indicators included sequential organ failure assessment (SOFA), mortality, the duration of vasoactive drugs, new acute kidney injury (AKI) patients, length of stay in intensive care unit (ICU) and in hospital. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. RevMan 5.3 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 6 articles involving 816 patients were included, with 411 patients in the experimental group and 405 patients in the control group. The Meta-analysis results showed that the duration of vasoactive drugs in the experimental group was significantly shorter than that in the control group [mean difference ( MD) = -24.02, 95% confidence interval (95% CI) was -32.36 to -15.68, P < 0.000 01]. However, there were no significant differences in SOFA, mortality, new AKI patients, the length of ICU stay and hospital stay between the two groups [SOFA: MD = -0.14, 95% CI was -1.15 to 0.87, P = 0.79; mortality: relative risk ( RR) = 0.99, 95% CI was 0.81 to 1.21, P = 0.92; new AKI patients: RR = 1.10, 95% CI was 0.42 to 2.87, P = 0.84; length of ICU stay: MD = 1.33, 95% CI was -2.22 to 4.89, P = 0.46; length of hospital stay: MD = 1.02, 95% CI was -0.66 to 2.69, P = 0.23]. The funnel plot showed that most of the points were symmetrical and showed an inverted funnel shape, suggesting that the publication bias among the studies was small. There was no significant publication bias on this Meta-analysis. Conclusions:Hydrocortisone combined with vitamin C and vitamin B1 can shorten the duration of vasoactive drugs in patients with sepsis or septic shock, but it cannot effectively reduce the SOFA score, mortality, new AKI patients, length of stay in ICU and in hospital. Limited by the number and quality of the included studies, further large-scale, multi-center, blinded, RCT are still needed for verification.

Objective To analyze the clinical data and TUBB4A mutation of hypomyelination with atrophy of the basal ganglia and cerebellum (HABC)in a family,thus to provide accurate genetic counseling and prenatal diagno-sis for this family with HABC,and also to provide clinical experience for the diagnosis of HABC in China.Methods The clinical data of the proband and her family members were collected at the Department of Pediatrics,Peking Univer-sity First Hospital,December 201 4,including medical history,physical signs,and brain MRI,biochemical tests and metabolic disease screening.The associated gene of hereditary leukoencephalopathy was screened for the proband and her family members were screened by targeting -high -throughput sequencing technology,and then the genetic varia-tions were verified by Sanger sequencing.With those detection methods,the gene mutation was confirmed,and then ge-netic features were analyzed.Results Clinical features were as follows:nystagmus as the first symptom,and motor and mental retardation,dystonia and ataxia followed.Brain MRI indicated hypomyelination of white matter and atrophy of the basal ganglia and cerebellum.The clinical diagnosis of HABC was established based on the clinical features and brain MRI features above.Genetics features showed that one novel TUBB4A c.974G >T heterozygous missense muta-tion was found from the proband,which caused an amino acid change from the Trp into Leu (p.Trp325Leu).Both of her parents with normal phenotype were of wild -type in this site.Conclusions The proband from this family was diagnosed clinically based on her clinical data.One novel TUBB4Ac.974G > T (p.Trp325Leu)was founded in this study.Therefore,the spectrum of TUBB4A mutation will be expanded.In addition,this study elucidated clinical and genetic characteristics in this family with HABC,which may lay a solid foundation for the accurate genetic counseling and prenatal diagnosis.This study reported the first case of HABC caused by TUBB4A mutation in China.

Objective We aim to evaluate and discuss the feasibility of Hyaline imaging of three-dimension sonography in observation of paravaginal support structure in normal nonporous women.Methods Total of 45 normal infertile women were chosen.Three-dimensional volume datasets were collected at rest by transperineal ultrasound.The three-dimensional Hyaline images were acquired off-line.We observed the morphologic features of paravaginal support structure on the axial plane in middle vagina and measured the anteroposterior and lateral horizontal distances between bilateral paravaginal support structure and ureter.The consistency between two sonographers were analyzed by intraclass correlation coefficient (ICC).Results In three-dimensional Hyaline imaging sonogram,paravaginal support structure was appeared as typically tenting-like shaped.The anteroposterior distances between paravaginal support structure and center of ureter were listed as followed:left (-0.31 ± 1.29) mm,right (0.47 ± O.99) mm.While the lateral horizontal distances were left (12.67 ± 6.70) mm,right (13.01 ± 5.75) mm.There were no statistical differences between bilateral both anteroposterior and lateral horizontal distances.The consistency between two sonographers for distinguishing paravaginal support structure on the middle-vaginal plane and measuring distances between paravaginal support structure and center of ureter was remarkably high (ICC is 0.87 and 0.82).Conclusions Hyaline imaging technology of three-dimensional pelvic floor sonography could be used to observe paravaginal support structure in women.The normal paravaginal support structure is typically showed as bilateral symmetrical tenting-like structure,which is on the same level as the center of ureter.It provides normal anatomic radiological evidence and helps study defect of paravaginal support structure caused by pregnancy or delivery.

Objective: To investigate the clinicopathological characteristics and prognostic factors of gastric stump cancer (GSC). Meth-ods: Clinicopathological data of 105 patients diagnosed with GSC at Tianjin Medical University Cancer Institute and Hospital between May 2004 and July 2017 were retrospectively analyzed. Results: Comparison of clinicopathological features of GSC-B and GSC-M: the average ages of the patients in the GSC-B and GSC-M groups were (63.22±8.95) and (58.93±10.06) years, respectively, and the male: fe-male ratios in the GSC-B and GSC-M groups were 17.5:1.0 and 2.6:1.0, respectively. The time intervals from initial surgery to the diag-nosis of GSC in the two groups were (390.95±95.18) and (64.53±73.15) months, respectively; the numbers of lymph nodes harvested in the GSC-B and GSC-M groups were 17.6±12.5 and 6.2±6.5, respectively; and the ratios of well differentiation to poor differentiation in the GSC-B and GSC-M groups were 0.89:1 and 0.20:1, respectively. The differences between all the above factors were statistically significant (P<0.05). Comparison of clinicopathological features of the anastomotic site group and non-anastomotic site group: there was no statistical difference between all the clinicopathological features (P>0.05). Univariate analysis showed that distant metastasis and R0 resection were prognostic factors in the patients with GSC. Multivariate analysis showed that R0 resection was an independent prognostic factor in the patients with GSC. Conclusions: The clinicopathological features of patients in the GSC-B and GSC-M groups were different. Patients with GSC would not benefit from palliative surgery if they could not receive radical surgery. R0 resection is an independent prognostic factor for patients with GSC.

Objective:To compare the effects of citrate and heparin anticoagulation on coagulation function and efficacy in children with septic shock undergoing continuous blood purification (CBP), and to provide guidance for CBP anticoagulation in children with septic shock.Methods:A case control study was conducted. Thirty-seven children with septic shock admitted to the pediatric intensive care unit (PICU) of the First Affiliated Hospital of Gannan Medical University from July 2019 to September 2022 were enrolled as the research subjects. The patients were divided into citrate local anticoagulation group and heparin systemic anticoagulation group according to different anticoagulation methods. The baseline data, the level of coagulation indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib), D-dimer] before treatment and 1 day after weaning from CBP, serum inflammatory mediators [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), hypersensitivity C-reactive protein (hs-CRP), procalcitonin (PCT)], bleeding complications during CBP and 7-day mortality were collected.Results:A total of 37 cases were enrolled finally, including 17 cases with citric acid local anticoagulation and 20 cases with heparin systemic anticoagulation. There was no statistically significant difference in general data such as gender, age, and body weight of children between the two groups. There were no statistically significant differences in baseline levels of coagulation indicators and inflammatory mediators before treatment of children between the two groups. One day after weaning from CBP, both groups showed varying degrees of improvement in coagulation indicators compared with those before treatment. Compared with before treatment, the PT of the heparin systemic anticoagulation group was significantly shortened after 1 day of weaning (s: 11.82±2.05 vs. 13.64±2.54), APTT and TT were significantly prolonged [APTT (s): 51.54±12.69 vs. 35.53±10.79, TT (s): 21.95±4.74 vs. 19.30±3.33], D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 4.94±3.94), with statistically significant differences (all P < 0.05). While in the citrate local anticoagulation group, only APTT was significantly prolonged after treatment compared with that before treatment (s: 49.28±10.32 vs. 34.34±10.32, P < 0.05). There were no statistically significant differences in other coagulation indicators compared with before treatment. Compared with the citric acid local anticoagulation group, the PT of the heparin systemic anticoagulation group was significantly shortened after treatment (s: 11.82±2.05 vs. 13.61±3.05, P < 0.05), and the D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 3.77±2.38, P < 0.01). The levels of inflammatory mediators in both groups were significantly reduced 1 day after CBP weaning compared with those before treatment [citric acid local anticoagulation group: hs-CRP (mg/L) was 12.53±5.44 vs. 22.65±7.27, PCT (μg/L) was 1.86±1.20 vs. 3.30±2.34, IL-6 (ng/L) was 148.48±34.83 vs. 202.32±48.62, TNF-α (ng/L) was 21.38±7.71 vs. 55.14±15.07; heparin systemic anticoagulation group: hs-CRP (mg/L) was 11.82±4.93 vs. 21.62±8.35, PCT (μg/L) was 1.90±1.08 vs. 3.18±1.97, IL-6 (ng/L) was 143.81±33.41 vs. 194.02±46.89, TNF-α (ng/L) was 22.44±8.17 vs. 56.17±16.92, all P < 0.05]. However, there was no statistically significant difference between the two groups (all P > 0.05). There was no statistically significant difference in bleeding complication during CBP and 7-day mortality in children between the citrate local anticoagulation group and the heparin systemic anticoagulation group (5.9% vs. 30.0%, 17.6% vs. 20.0%, both P > 0.05). Conclusions:Heparin for systemic anticoagulation and regional citrate anticoagulation can significantly reduce the levels of IL-6, TNF-α, hs-CRP and PCT in children with septic shock, and relieve inflammatory storm. Compared with citric acid local anticoagulation, heparin systemic anticoagulation can shorten the PT and reduce the level of D-dimer in children with septic shock, which may benefit in the prevention and treatment of disseminated intravascular coagulation (DIC).
