Objective : Objective To investigate the demand for health management and influencing factors among occupational population at high risk of stroke, so as to provide insights into the development of stroke health management strategies among occupational population. Methods: Occupational population aged 40 to 60 years who participated in health examination were sampled from three tertiary hospitals in Luzhou City, Sichuan Province using a quota sampling method in the ratio of 4∶1∶1, from August to December 2020. Participants' blood biochemistry tests and health examination were collected through the examination reports, and the participants at high risk of stroke were screened using the assessment criteria for high-risk of stroke. Participants' general information and demand for health management were collected using questionnaire surveys. In addition, factors affecting the demand for health management were identified using a multivariable logistic regression model. Results: A total of 3 003 people who participated in health examination were investigated, and 1 062 participants met the assessment criteria for high risk of stroke, accounting for 35.36%. There were 1 000 men (94.16%) and 62 women (5.84%), with a mean age of (49.26±4.97) years. There were 414 professional and technical staff (39.50%). There were 709 participants (66.76%) with demand for health management, with the top three in the demand as health checkups (915 participants, accounting for 86.16%), health consultation (601 participants, accounting for 56.60%) and exercise guidance (560 participants, accounting for 52.73%), and 210 participants (19.77%) received health management. Multivariable logistic regression analysis showed that occupational population at high risk of stroke who received health management were more likely to have the demand for health management (OR=2.158, 95%CI: 1.479-3.149). Conclusions The occupational population at high risk of stroke have the demand for health management. Having received health management may affect the demand for health management among occupational population at high risk of stroke.

Objective To explore the effects of probiotics on feeding intolerance and early growth and development of premature infants.Methods Eighty premature infants were randomly assigned into 2 groups,the other 40 infants as therapy group,another 40 infants as control group.All infants in 2 groups were given general care and treatment.At the same time,probiotics was administered orally or via a orogastric tube to infants in therapy group within 24 hours after birth.The parameters of head circumference,length and body weight on day 28 of life and the time to achieve full enteral feeding and to regain birth weight were all recorded.The incidence of feeding intolerance of both groups were analyzed.Potential adverse effects associated with probiotics were also monitored.Results The incidence of feeding intolerance was significantly lower in probiotics-treated infants(27.5%) compared with that of control group(52.5%)(?2=5.208 3 P

Proteasome inhibitors have shown remarkable success in the treatment of hematologic neoplasm. There has been a lot of attention to applying these drugs for solid tumor treatment. Recent preclinical study has signified the effectiveness on cell proliferation inhibition in lung adenocarcinoma treated by carfilzomib (CFZ), a second generation proteasome inhibitor. However, no insight has been gained regarding the mechanism. In this study, we have systematically investigated the CFZ functions in cell proliferation and growth, cell cycle arrest, and apoptosis in lung adenocarcinoma cells. Flow cytometry experiments showed that CFZ significantly induced G2/M cell cycle arrest and apoptosis in lung adenocarcinoma. MTS and colony formation assays revealed that CFZ substantially inhibited survival of lung adenocarcinoma cells. All results were consistently correlated to the upregulation expression of Gadd45a, which is an important gene in modulating cell cycle arrest and apoptosis in response to physiologic and environmental stresses. Here, upregulation of Gadd45a expression was observed after CFZ treatment. Knocking down Gadd45a expression suppressed G2/M arrest and apoptosis in CFZ-treated cells, and reduced cytotoxicity of this drug. The protein expression analysis has further identified that the AKT/FOXO3a pathway is involved in Gadd45a upregulation after CFZ treatment. These findings unveil a novel mechanism of proteasome inhibitor in anti-solid tumor activity, and shed light on novel preferable therapeutic strategy for lung adenocarcinoma. We believe that Gadd45a expression can be a highly promising candidate predictor in evaluating the efficacy of proteasome inhibitors in solid tumor therapy.

Objective To carry out mutation analysis of deafness-associated genes for deaf newborns and their parents, and to estimate the recurrence risk for their parents to have deaf descendants.Methods Suspected cases of inherited deafness were identified by neonatal hearing screening and questionnaires. Genomic DNAs of suspected cases and their parents were extracted from their peripheral blood samples . Common deafness-associated genes(i.e. GJB2,SLC26A4 and 12S rRNA genes)were amplified by polymerase chain reaction(PCR),and those PCR products were sequenced for the mutation analysis.Results From 2013 to 2016, 193 cases of deafness were found in neonatal hearing screening,29 cases of suspected as hereditary deafness were screened,and 17 out of 29 cases were found to have mutations in deafness-associated genes(detection rate:58.62%). GJB2 homozygous mutations were identified in two cases and their parents,and the recurrence risk to have deaf descendants was 100%. Four cases of suspected hereditary deafness had GJB2 homozygous mutations,and their parents were both GJB2 mutation carriers. There was one case with SLC26A4 homozygous mutations,and their parents were both SLC26A4 mutation carrier. Two cases were detected to have GJB2 V371 homozygous mutations,and their parents were both GJB2 V371 mutation carriers. For those seven parents carrying deafness-associated mutations above,the recurrence risk of deafness for their descendants was 25%.Conclusion In addition to hearing screening,the genetic diagnosis of deafness-associated genes is helpful to clarify the cause of suspected neonatal hereditary deafness,and can provide objective reproductive counseling and guidance for those deaf parents or parents with deaf children.

OBJECTIVE: To explore clinical effect of arthroscopy-assisted rotator cuff tendon transfer in treating irreparable rotator cuff tears (IRCT). METHODS: From May 2015 to May 2018, 23 patients with unrepairable rotator cuff tears were treated with arthroscopy-assisted rotator cuff tendon transfer, and 21 patients were followed up finally, including 8 males and 13 females, aged from 48 to 82 years old with an average of(64.3±9.1) years old;the courses of disease ranged from 6 to 36 months with an average of (14.0±6.4) months. American Rotator and Elbow Surgeons Score(ASES) and Constant-Murley score were used to evaluate clinical efficacy before surgery and at the latest follow-up. RESULTS: All 21 patients were followed up for 36 to 54 months with an average of (39.4±4.4) months. Axillary incision of 1 patient was redness, swelling and exudation after surgery, which healed after 3 weeks of dressing change, and exudate culture was negative. At the latest follow-up, MRI showed partial tearing of the metastatic tendon in 2 patients, but pain and movement of the affected shoulder were still better than before surgery. ASES increased from preoperative (41.0±9.6) scores to the latest follow-up (75.6±14.0) scores, and had statistical difference (t=10.50, P<0.01). Constant-Murley score increased from (49.8±7.1) scores before operation to (67.5±11.6) scores at the latest follow-up (t=11.27, P<0.01). CONCLUSION Arthroscopic assisted latissimus dorsalis tendon transposition restores physiological and anatomical structure of glenohumeral joint by reconstructing balance of horizontal and vertical couples of shoulder joint, thus achieving the stability of the shoulder joint, relieving shoulder pain and improving shoulder joint function.

AIMTo clarify the ultrastructural changes of penile tunica albuginea (TA) in streptozotocin (STZ)-induced diabetic rats.

METHODSIntraperitoneal injection of STZ was used to induce diabetes mellitus (DM) in 12 Sprague Dawley rats. Ten rats (age and weight-matched) were used as control. Blood samples from the tail snips of the rats were used for the determination of serum glucose levels with SureStep Plus Blood Meter. At week 4 and 10 after the injection, half of the rats in each group were sacrificed and penile samples were obtained from the middle third of the penile shaft for the examination of TA under scanning electron microscopy.

RESULTSIn the diabetic group, the serum glucose levels were higher (P<0.01 at both time points) and the TA were thinner (P<0.05) than those of the controls. In the control group, the fibers of TA were rich and arranged regularly and undulated, while in the diabetic group, the fibers were diminished, lost the undulations and were arranged irregularly.

CONCLUSIONIn rats, DM appeared to impair the penile TA ultrastructures and this impairment could contribute to diabetic erectile dysfunction in part by impairing the veno-occlusive function.

OBJECTIVETo investigate the potential effects on cognitive function, prognosis, and neuropeptide levels of patients in response to combination therapy with ornithine aspartate plus naloxone for hepatic encephalopathy.

METHODSEighty-four consecutive patients diagnosed with hepatic encephalopathy were randomly divided into two equal groups. The control group (n = 42) received traditional medical treatment, and the research group (n = 42) received the traditional medical treatment as well as the combination therapy with ornithine aspartate plus naloxone. The supplemental treatment was comprised of daily intravenous injection of 10-15 g ornithine aspartate in 250 ml of 5% glucose plus intravenous drip of 3 mg naloxone in 100 ml of 5% glucose, and was given in 7-day cycles for one or two cycles. The cognitive function of patients was assessed by Hasegawa Intelligence Scale (HDS) and Mini-Mental State Examination (MMSE) questionnaires. The effective rate and time duration from coma to consciousness were recorded. Changes in blood ammonia level, markers of liver function, and neuropeptide levels were measured by standard biochemical assays. Intergroup differences were assessed by the Chi-squared test.

RESULTSThe HDS and MMSE scores of the research group were significantly higher than those of the control group after therapy. The effective rate, time duration from coma to consciousness, blood ammonia, the liver function markers alanine aminotransferase, gamma-glutamyl-transpeptidase and total bilirubin, and the neuropeptides arginine vasopressin and beta-endorphin were remarkably improved after treatment in the research group, as compared with that in the control group.

CONCLUSIONSupplementing the traditional treatment for hepatic encephalopathy with ornithine aspartate plus naloxone combination therapy provides better therapeutic outcome than traditional treatment alone.

OBJECTIVETo construct COL1A1-targeted short hairpin RNA (shRNA) vector with pSilencer 4.1-CMV neo siRNA expression vector and to evaluate its effect on proliferation and migration of gastric cancer BGC-823 cells in vitro.

METHODSThree COL1A1-shRNA plasmids (COL1A1-shRNA-1, COL1A1-shRNA-2, COL1A1-shRNA-3), targeting different sites of COL1A1 gene, were constructed using pSilencer 4.1-CMV neo siRNA expression vector and transfected into gastric cancer BGC-823 cells. Real time quantitative RT-PCR and Western blot were performed to detect expression levels of COL1A1. MTT and Transwell migration assays were employed to evaluate the effects of COL1A1 gene silence on cell proliferation and migration.

RESULTThree recombinant plasmids targeting COL1A1 were constructed successfully. The expressions of COL1A1 in BGC-823 cells, including mRNA and protein levels, were significantly inhibited by the COL1A1-shRNA transfectants, which resulted in a clear reduction of cell proliferation and migration capacity.

CONCLUSIONThe COL1A1-shRNA can effectively knock down gene expression and inhibit proliferation and migration of gastric cancer BGC-823 cells.

OBJECTIVETo investigate the relationship between alanine aminotransferase (ALT) levels and metabolic syndrome (MS) in nonalcoholic fatty liver disease (NAFLD).

METHODSA total of 26527 subjects who received medical health checkup in our hospital from January 2005 to July 2007 were enrolled in the study. The diagnosis of fatty liver was based on ultrasound imaging. MS was defined according to the criteria of the Adult Treatment Panel III. ALT, triglyceride (TG), high density lipoprotein cholesterol (HDL-c), fasting plasma glucose (FPG), height, weight, waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured in each subject to analyze the relationship between MS and ALT activity.

RESULTS(1) The prevalence of NAFLD in men (30.94%) was significantly higher than that in women (15.65%); (2) The incidence of MS in NAFLD (33.83%) was significantly greater than that in non-NAFLD (10.62%); (3) Of the 6470 subjects with NAFLD, in the age-adjusted partial correlation analysis, there were statistically significant correlations between the ALT levels and most metabolic risk factors in each sex (P<0.01), except that ALT levels had no correlation with HDL-c in women. Moreover, in the multiple stepwise regression analysis, SBP lost its significance, and WC, body mass index (BMI), age, DBP, TG and FPG were independently associated with ALT levels in both sexes (P<0.05). HDL-c remained significant and was independently related to ALT levels in men; (4) ALT levels were significantly higher in subjects with MS compared to those without MS (P<0.001). Mean ALT levels increased with the number of MS components in each sex (P<0.05 for trend).

CONCLUSIONWe found a strong relationship between ALT levels and MS in NAFLD and revealed that the cluster of MS components might be the predictor for ALT elevations.

OBJECTIVETo observe the effects of antisense RNA of connective tissue growth factor (CTGF) on rat liver fibrosis.

METHODSGene recombinant techniques were used to construct a rat antisense RNA of CTGF recombinant plasmid which could be expressed in eukaryotic cells. The recombinant plasmids were encapsulated with lipofectamine and then transducted into a carbon tetrachloride (CCl4) induced rat liver fibrosis model. Expression of CTGF was assessed by RT-PCR, Western blot and immunohistochemistry. Immunohistochemistry was used to identify type I and III collagens. HE stained liver slides were used for pathological study.

RESULTSThe mRNA and protein expression of CTGF in the fibrotic liver transfected with antisense-CTGF were significantly decreased compared with those of the controls (P<0.01). The depositions of type I and type III collagens were also decreased (P<0.05). Antisense-CTGF also minimized the pathological fibrosis in the rat livers (P<0.01).

CONCLUSIONThe results demonstrate that the antisense RNA of CTGF recombinant plasmid has certain effects in preventing liver fibrosis and makes it a possible candidate for use in future gene therapy.
