BACKGROUND: Total hip arthroplasy is an effective method to treat hip disease caused by ankylosing spondylitis. Long-term fol ow-up studies have shown that there have been hip function problems after total hip arthroplasy, and it stil lacks of perfect rehabilitation programs. OBJECTIVE: To systematical y review the influential factors for dysfunction after total hip arthroplasy in ankylosing spondylitis patients. METHODS: The first and second authors retrieved PubMed and Sciencedirect Databases, CNKI, and Wanfang digital database for relevant articles published from January 1970 to July 2015. The key words were “arthroplasty, replacement, hip, spondylitis, ankylosing, function”. Final y, relevant articles were included. RESULTS AND CONCLUSION: A total of 40 articles were summarized, including 8 Chinese articles and 32 English articles. After total hip arthroplasy, hip function problems were mainly associated with patient’s factors, disease, surgery, prosthesis, postoperative recovery and postoperative complications. Avoiding above relevant factors can improve joint function after total hip arthroplasy for ankylosing spondylitis patients, and improve patient’s quality of life.

Objective:To investigate the epidemiological and clinical features of patients with hemorrhagic fever with renal syndrome (HFRS) from 2017 to 2019.Methods:Seventy-five patients with HFRS from the Department of Infectious Diseases, The First Affiliated Hospital of Anhui Medical University during January 1, 2017 to December 31, 2019 were included. The data of epidemiology, clinical symptoms, blood routine, urine routine, serum creatinine, liver function and other laboratory examination indexes were retrospectively analyzed. The measurement data with skewness distribution were expressed by M( QR) and compared by nonparametric test. Multivariate logistic regression analysis was used to analyze disease-related risk factors. Results:The 75 patients were mainly located in the western and northern regions of Anhui Province. A total of 37 cases (49.3%) were infected during November, December and January next year. Fifty-four (72.0%) patients were farmers and 10(13.3%) patients had a clear history of rodent contact. Only 19(25.3%) patients had typical clinical manifestations of "three red and three pain" . Fifty-eight (77.3%) patients had elevated white blood cell count, 67(89.3%) patients had decreased platelet count, 55(73.3%) patients had urinary protein + + + , 65(86.7%) patients had abnormal urinary occult blood, and 67(89.3%) patients had elevated serum creatinine. The serum creatinine and potassium levels in 31 severe and critical patients were 495(301) μmol/L and 4.14(0.77) mmol/L, respectively, which were both higher than those in 44 mild and moderate patients (235(289) μmol/L and 3.65(1.02) mmol/L, respectively). The differences were both statistically significant ( Z=-3.187 and -2.796, respectively, both P<0.01). Multivariate logistic regression analysis showed that serum creatinine (odds ratio ( OR)=1.005, 95% confidence interval ( CI)1.002-1.008) and serum potassium ( OR=2.632, 95% CI 1.098-6.313) were independent risk factors for disease severity. All patients received comprehensive medical treatment, and 27 patients received renal replacement therapy. Sixty-eight patients had good prognosis and four patients died. Conclusions:HFRS is still common in the rural area in winter and spring. Patients with atypical clinical manifestations and severe and critical patients should be intensively monitored.

Objective To observe the dynamic changes of Notch1 protein expression in the subventricular zone (SVZ) after traumatic cerebral injury (TBI) in rats,and to explore the correlation between Notch signaling pathway and neural stem cells (NSCs) proliferation after TBI.Methods Ninety-six SD rats were randomly divided into sham-operated group (only opening the scalp and shall window,n=16),control group (without any treatment,n=16) and experimental group (establishing medium-sized TBI models with Feeney's free fall method,n=64);rats in the experimental group were divided into 4 sub groups according to the execution times (one,three,7 and 14 d after TBI,n=16).Immunofluorescence staining was performed to detect the Notchl/nestin labeled cell expressions in SVZ of rats,and Notch1 protein expression was detected by Western blotting.Results Immunofluorescence results showed that the Notch1/nestin double staining positive cells in the right SVZ brain tissues of the experimental group on the first day of TBI had peak level,which was 2-3 times of the control group;and then,it gradually declined and basically returned to normal on 144 day of TBI;the differences between the 4 subgroups were statistically different (P＜0.05).The positive cell counts in the subgroups of first,third,and 74 d after TBI were statistically different as compared with those in the control group and sham operated group (P＜0.05).Western blotting results indicated that there was no significant difference in the Notch1 protein expression between control group and sham operated group;Notch1 protein expression in SVZ of the experimental group had peak level on the first day of TBI,gradual decline was noted after that,and normal level was noted on the 14th d of TBI.Conclusion TBI can activate the Notch1 protein expression,which induces the opening of Notch signaling pathway so as to affect the regulation of NSCs proliferation.

Aim To explore the growth inhibition effects of jasmonates on human neuroblastoma SH-SY5Y cell line,and to investigate its mechanisms.Methods After administration of 0.5~2.5 mmol?L-1 jasmonates for 6~24 hrs, the growth inhibition rates of SH-SY5Y cells were studied by MTT colorimetry.Cell cycle phases were assayed by propidium iodide staining flow cytometry. Cellular apoptosis was inspected by Hoechst 33258 fluorescent staining and Annexin V-FITC and propidium iodide staining flow cytometry.Gene expressions of PCNA, cyclin D1 and N-myc were determined by reverse transcription polymerase chain reaction.Results Jasmonates inhibited the growth of SH-SY5Y cells in a dose-and time-dependent manner,while the methyl jasmonate was the most efficient. After administration of 0.5 to 2.5 mmol?L-1 of methyl jasmonate for 24 hrs,the growth inhibition rates of cells reached 5.75%~88.7%(P

OBJECTIVETo investigate the correlation between intrahepatic eovalently closed circular (ccc)DNA of hepatitis B virus (HBV) and pathogen-and patient-related parameters.

METHODSUltrasound-guided liver biopsies were obtained from 60 patients with chronic HBV infection. Levels of intrahepatic HBV cccDNA and serum HBV DNA were measured by quantitative fluorescence PCR. Level of serum hepatitis B surface antigen (HBsAg) was measured by chemiluminescence immunoassay. Clinical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (AKP), albumin, globulin (GLO), white blood cell, platelet, prothrombin-international normalized ratio, were measured by standard assay. Demographic information was recorded.The correlation between intrahepatic HBV cccDNA and pathogen-and patient-related parameters was assessed.

RESULTSIntrahepatic HBV cccDNA level was negatively correlated with age, GLO, ALT and grade of necroinflammation. Patients with age of 30 years or more showed significantly higher level of HBV cccDNA level than patients under 30 years-old (7.44±0.58 and 5.66±1.35; t=7.157, P less than 0.001). Intrahepatic HBV cccDNA level was positively correlated with serum HBV DNA level (r=0.916, P less than 0.001) and serum HBsAg level (r=0.727, P less than 0.001). The median ratio of HBV cccDNA to HBV DNA was 1.18, and of HBV cccDNA to HBsAg was 1.67.

CONCLUSIONIntrahepatic HBV cccDNA levels decrease with age, level of ALT, level of GLO and grade of liver necroinflammation, but increase with level of serum HBV DNA and level of serum HBsAg. To a certain extent, serum HBV DNA and serum HBsAg levels may be a sufficient marker of intrahepatic HBV cccDNA levels.

OBJECTIVE:To provide reference for the further research and development of bamboo juice. METHODS:Comb-ing the ancient and modern literatures,the processing historical evolution,origins,technology,chemical ingredients,quality stan-dards and efficacy were analyzed,the problems were found and solutions were put forward. RESULTS:Bamboo juice's processing can be traced back to the Liang Dynasty,still being used today with light bamboo juice. And now,varieties of bamboos(Phyllo-stachys glauca,Phyllostachys viridiglaucescens,Pleioblastus amarus,and Neosino calamus,etc.) were processed into medicine. The research for the chemical ingredients was mainly for the changes of bamboo juice with different varieties and amino acids,phe-nols,organic acids and inorganic elements in bamboo juice with different technologies,and there was no comprehensive study on the material basis of bamboo juice. Its quality standards must be improved. Although there was comparative study for the traditional processing technology and modern technology in chemical ingredients,the study did not compare the efficacy of its material founda-tions. The research for the efficacy of bamboo juice only involved relieving cough and resolving phlegm,and its relieving convul-sion,resuscitation,calming diabetes and other pharmacological effects haven't been reported. CONCLUSIONS:In the future, in-dept research can be carried out from the aspects of standardizing the name,base source and processing technology parameters, improving quality standards,strengthening basic research of effective substances,and improving traditional technology and equip-ment level.

Objective:To investigate the clinical management value of chitinase 3-like 1 protein(CHI3L1) in hepatocellular carcinoma (HCC) by studying the expression of CHI3L1 in peripheral blood, liver cancer and paired adjacent non-tumor tissues.Methods:Retrospective study. From 2013 to 2017, 405 patients with HCC in Third Affiliated Hospital of Naval Medical University were enrolled into the study. Meanwhile, 112 patients with liver cirrhosis (LC), 114 health subjects were included as disease and health controls. CHI3L1 in peripheral blood was detected by ELISA kit. Tissues array was made by collecting 90 pairs of tumor tissues and matched paracancer tissues, from HCC patients who were conformed by pathology. The expression of CHI3L1 in HCC tissues was analyzed by immunohistochemistry. Differences between independent groups were tested by Mann-Whitney U test or Kruskal Wallis H test, Pearson correlation analysis was used for analyzing the relationship between two subjects, and matched rank sum test was used for cancer tissue and adjacent tissue comparison. Results:The median (quartile) of CHI3L1 protein in LC group, HCC group and NC group was 195.8 (103.3,330.4) μg/L,118.2 (74.9,201.0) μg/L,46.8 (30.7,66.4) μg/L independently. The protein level of CHI3L1 in LC group was significantly higher than that in HCC group and health control group ( Z=5.186,12.928, P<0.001). HCC group was significantly higher than that in health control group ( Z=10.788, P<0.001). The level of CHI3L1 in HCC group was not related to whether liver cirrhosis was accompanied ( Z=-0.286, P=0.775). The level of serum CHI3L1 was positively correlated with noninvasive fibrosis markers (HA, PⅢNP, Ⅳ-C, FIB-4 index) ( r=0.202,0.159,0.299 and 0.221, P<0.05) and negatively correlated with ALB( r=-0.326, P<0.05) while positively correlated with AST and PT( r=0.138, 0.160, P<0.05). Positively correlation was observed between CHI3L1 and tumor size ( r=0.284, P<0.001). CNLC stage [CHI3L1 level in advanced group125.2(81.9,228.5)μg/L was higher than that in early group112.0(70.2,169.2)μg/L ( Z=-2.326, P=0.018)], but no correlation with microvascular invasion( Z=-1.531) and tumor capsule(χ 2=0.818, P>0.05). In 73 cases of HCC tissues, the positive rate of CHI3L1 was 78% (57/73) in cancer tissues and 83%(61/73) in paired adjacent non-tumor tissues. The staining intensity score of paracancer tissue 1.5(1.5,2.5) was higher than that of cancer tissue 1.5(1.5,2.0)( Z=-2.053, P=0.040). Conclusions:The tissue source of CHI3L1 protein in HCC includes cancer tissue and paracancerous tissue. The detection of serum CHI3L1 level is helpful to evaluate tumor load assessment and disease stratification management in HCC.

OBJECTIVE: To explore the effect of 1,2-dichloroethane(1,2-DCE) induced apoptosis on the expression of related proteins in human neuroblastoma cells(SH-SY5 Y cells). METHODS: SH-SY5 Y cells were cultured in complete medium with 1,2-DCE at final concentrations of 0,10,20,30,40,50,60,70 and 80 mmol/L. After being cultured for24 hours,the apoptosis of SH-SY5 Y cells was tested by flow cytometry using annexin Ⅴ-fluorescein isothiocyanate and propidium iodide. Western blot was used to detect the protein expression of P53,B cell lymphoma/leukmia-2(BCL-2)and BCL-2 associated X protein(BAX). RESULTS: At 1,2-DCE concentrations of 0-80 mmol/L,the total apoptosis rate of SH-SY5 Y cells increased with 1,2-DCE concentrations in a dose-dependent manner(P < 0. 01). At 1,2-DCE concentrations of 30-80 mmol/L,the early apoptosis rate and total apoptosis rate of SH-SY5 Y cells increased significantly than the control group(P < 0. 05). Compared with the other groups,the protein expression of P53 was the lowest when the1,2-DCE concentration was 20 mmol/L(P < 0. 05),and the protein expression of BCL-2 and the BCL-2/BAX ratio were the lowest when the 1,2-DCE concentration was 70 mmol/L(P < 0. 05). There is no dose-response relationship in the1,2-DCE concentrations and the protein expression levels of P53,BCL-2 and BAX,and BCL-2/BAX ratio. Linear multiple regression analysis revealed that the total apoptosis rate of SH-SY5 Y cells treated with 1,2-DCE was associated with the protein expression of P53 and BCL-2,and BCL-2/BAX ratio(P < 0. 05). CONCLUSION: 1,2-DCE could inhibit the apoptosis of SH-SY5 Y cells. The mechanisms may be related to the changes of P53 and BCL-2 protein expression,and BCL-2/BAX relative amount.

Objective:To investigate the influencing factors of operation time for laparos-copic sleeve gastrectomy (LSG) and analyze the learning curve of LSG in sarcopenic obesity (SO) and non-sarcopenic obesity (NSO).Methods:The retrospective cohort study was conducted. The clinical data of 240 obesity patients who underwent LSG in the Fujian Medical University Union Hospital from January 2018 to June 2022 were collected. There were 52 males and 188 females, aged (30±8)years. Patients underwent L3 vertebral body horizontal axial computer tomography (CT) scanning before and after receiving LSG to accurately segment muscles and fats. Observation indicators: (1) treatment and follow-up; (2) influencing factors of operation time for LSG; (3) cumulative sum (CUSUM) of learning curve; (4) comparison of clinical data between patients in the initial and profi-cient stages. Measurement data with normal distribution were represent as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(IQR), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Univariate and multivariate analyses were conducted using the Logistic regression model. The CUSUM of learning curve was calculated and the fitting process was conducted on scatter plot of learning curves. Results:(1) Treatment and follow-up. Of the 240 patients, there were 97 cases of SO and 143 cases of NSO. All 240 patients underwent LSG successfully, without conversion to open surgery. The operation time of 240 patients was (108±23)minutes. None of patient died during the perioperative period and all patients underwent follow-up during the postoperative 6 months. (2) Influencing factors of operation time for LSG. Results of multivariate analysis showed that SO was an independent factor influencing operation time for LSG ( odds ratio=2.207, 95% confidence interval as 1.207-4.038, P<0.05). (3) CUSUM of learning curve. Results of CUSUM of operation time in patients of SO and NSO showed that the best fit equation of patients of SO was y=-4E-08x 6+1E-05x 5-0.001 1x 4+0.063 1x 3-1.89x 2+28.126x-48.671 (x means the number of surgical cases), with goodness-of-fit R 2 as 0.833, and the best fit equation of patients of NSO was y=3E-09x 6-1E-06x 5+0.000 2x 4-0.010 9x 3+0.063 8x 2+12.053x-65.025 (x means the number of surgical cases), with goodness-of-fit R 2 as 0.716. Based on the trend of CUSUM of learning curve of operation time, the peak value of number of surgical cases in patients of SO and NSO was 81 and 36, respec-tively, which was used to divide the learning curve as two stages of the initial stage and the proficient stage. (4) Comparison of clinical data between patients in the initial and proficient stages. ① Of the 97 patients of SO, there were 81 cases and 16 cases in the initial stage and the proficient stage of LSG, with the operation time, postoperative duration of hospital stay as (119±23)minutes, (5.9±2.3)days and (106±21)minutes, (4.7±0.5)days, showing significant differences between them ( t=2.074, 2.147, P<0.05). ②Of the 143 patients of NSO, there were 36 cases and 107 cases in the initial stage and the proficient stage of LSG, with gender (female), height, preoperative body mass, defatted body mass, operation time, postoperative duration of hospital stay, body mass at postoperative 6 month, body mass index (BMI) at postoperative 6 month, percentage of excess weight loss (EWL%) at postoperative 6 month, cases with EWL% >100% at postoperative 6 month, excess BMI at post-operative 6 month as 20, (170±10)cm, (110±25)kg, (57±12)kg, (108±22)minutes, (6.1±1.6)days, (80±16)kg, (27.63±4.22)kg/m2, 83%±35%, 9, 1.99(6.03)kg/m2 and 87, (164±8)cm, (99±20)kg, (52±12)kg, (100±19)minutes, (4.7±1.1)days, (71±16)kg, (25.89±4.48)kg/m2, 103%±42%, 48, 0.31(5.82)kg/m2, showing significant differences between them ( χ2=9.484, t=3.266, 2.424, 2.141, 2.137, 5.821, 2.740, 1.993, -2.524, χ2=4.432, Z=-2.300, P<0.05). Conclusions:SO is an independent factor influencing operation time for LSG. It is suggested that the surgeons need to finish 81 cases and 36 cases master LSG in patients of SO and NSO.
