Liver fibrosis is a necessary stage in the development of chronic liver diseases to liver cirrhosis. Liver cirrhosis is the end-stage change of various chronic liver diseases, and early diagnosis of liver fibrosis has an important value in timely treatment and prognosis. At present, liver biopsy, ultrasound, computed tomography, and magnetic resonance imaging are the main diagnostic methods for liver fibrosis and cirrhosis. Liver biopsy is the gold standard for the diagnosis of liver fibrosis and cirrhosis, but its clinical application is limited by invasiveness and sample error. Conventional noninvasive methods cannot meet the requirements for the diagnosis of liver fibrosis and cirrhosis. Therefore, searching for new serological markers for liver fibrosis and cirrhosis has become a research hotspot. Related studies have shown that serum Golgi protein 73 (GP73) can be used as a serum marker for the diagnosis of liver fibrosis and cirrhosis and has high clinical value. This article reviews the commonly used methods for the diagnosis of liver fibrosis and cirrhosis and elaborates on the biological characteristics of GP73 and its value in the diagnosis of liver fibrosis and cirrhosis.

Objective: To study the mechanism of jindengshanggen (JDSG) oral liquid's anti infectiion effect.Methods: inhibition on bacteria growth, resistance to Escherichia coli endotoxin and measurement of monocytic phagocaryosis in mice were taken. Results: The effects of JDSG oral liquid is probably not due to the inhibition on bacteria growth, but rather due to its stimulation on other anti infection mechanisms in human body. The enhancement of immune response and toxin tolerance may be one of the mechanisms for JDSG oral liquid to cure acute pharynx infection. Conclusions: These results provide a basis for clinical application of JDSG.

Objective:To investigate the changes of cardiomyocyte apoptosis after hypoxia/reoxygenation (H/R) regulated by microRNA-1 (miR-1).Methods:Cardiomyocyte strain H9c2 derived from rat embryonic heart tissue were cultured in vitro. The cells in logarithmic growth phase were divided into blank control group, H/R group, miR-1 mimics+H/R group, miR-1 inhibitor antisense oligonucleotide (ASO)+H/R group and microRNA negative control fragment (miRNA NC)+H/R group. The low sugar DMEM medium containing low concentration of fetal bovine serum (FBS) was used as the medium under anoxic condition. After being cultured in a closed anaerobic incubator at 37 ℃ (95% N 2 and 5% CO 2) for 12 hours, the cells were cultured with the fresh high sugar DMEM medium containing 5% FBS in a closed incubator at 37 ℃ for reproducing cardiomyocyte H/R model. The blank control group was cultured in high glucose DMEM medium containing 10% FBS in 37 ℃ and 5% CO 2 incubator. In miR-1 mimics+H/R group, miR-1 ASO+H/R group and miRNA NC+H/R group, the corresponding transfectants were mixed in high glucose DMEM medium and transfected into cells before H/R model was established, and the final concentration was 50 nmol/L. The blank control group and H/R group were added with DMEM medium at the same time. After the establishment of the model, the expression level of miR-1 was detected by real-time fluorescence quantitative polymerase chain reaction (qPCR). The expression levels of apoptosis-related proteins caspase-9, Bcl-2 and Bax were detected by Western blotting, and cardiomyocyte apoptosis was detected by flow cytometry. Results:Compared with the blank control group, the expression levels of miR-1, caspase-9 and Bax protein and the apoptosis rate of cardiomyocytes were significantly increased, while the expression level of Bcl-2 was significantly decreased, which indicated that the expression of miR-1 and the level of apoptosis were increased in H/R group. Compared with H/R group, the expressions of miR-1, caspase-9 and Bax and the apoptosis rate of cardiomyocytes in miR-1 mimics+H/R group were further increased [miR-1 (2 -ΔΔCt): 11.59±1.48 vs. 2.57±0.38, caspase-9 protein (caspase-9/β-actin): 2.59±0.12 vs. 1.56±0.20, Bax protein (Bax/β-actin): 4.09±0.38 vs. 1.97±0.13, apoptosis rate: (25.23±0.87)% vs. (17.86±0.73)%, all P < 0.01], while the expression of Bcl-2 was decreased (Bcl-2/β-actin: 0.37±0.02 vs. 0.49±0.03, P < 0.01). The expressions of miR-1, caspase-9 and Bax and the apoptosis rate were significantly decreased in miR-1 ASO+H/R group [miR-1 (2 -ΔΔCt): 1.16±0.06 vs. 2.57±0.38, caspase-9 protein (caspase-9/β-actin): 1.05±0.24 vs. 1.56±0.20, Bax protein (Bax/β-actin): 0.93±0.11 vs. 1.97±0.13, apoptosis rate: (11.19±0.85)% vs. (17.86±0.73)%, all P < 0.05], while the expression of Bcl-2 was increased (Bcl-2/β-actin: 0.84±0.17 vs. 0.49±0.03, P < 0.05). There was no significant difference in miR-1 expression, caspase-9, Bax and Bcl-2 protein expressions, and apoptosis rate between H/R+miRNA NC group and H/R group. Conclusion:The expression of miR-1 and level of apoptosis were increased in H/R cells, and miR-1 could aggravate cardiomyocyte apoptosis.

Objective: To investigate the current status of occupational mental health and job satisfaction in university teachers in Shenyang, China and related influencing factors. Methods: A total of 1500 teachers from 6 universities in Shenyang were randomly selected as study subjects from November 2013 to January 2014. Self-administered questionnaires were used to investigate mental health, including effort-reward imbalance questionnaire, Minnesota Satisfaction Questionnaire, Center for Epidemiological Survey-Depression Scale, and Psychological Capital Questionnaire. Results: Of all teachers, 58.9% had depressive symptoms. Depressive symptoms in university teachers were negatively correlated with the scores of psychological capital, supervisory commitment, and perceived organizational support (r=-0.461, -0.306, and -0.366, all P<0.01) and were positively correlated with the score of occupational stress (r=0.414, P<0.01) . Job satisfaction was positively correlated with psychological capital, perceived organizational support, and supervisory commitment (r=0.650, 0.715, and 0.636, all P<0.01) and negatively correlated with occupational stress (r=-0.475, P<0.01) . The direct effects of occupational stress, perceived organizational support, and supervisory commitment on job satisfaction were -0.30, 0.26, and 0.14, respectively, and their indirect effects were -0.0176, 0.0656, and 0.0368, respectively. The direct effects of occupational stress, perceived organizational support, and supervisory commitment on depressive symptoms were 0.20, -0.08, and -0.05, respectively, and their indirect effects was 0.033, -0.123, and -0.069, respectively. Conclusion Occupational mental health is closely associated with job satisfaction in university teachers in Shenyang, and psychological capital has a mediating effect on perceived organizational support, supervisory commitment, occupational stress, job satisfaction, and depressive symptoms.

Objective The aims of this study were to determine the expression of Ki-67 and PTEN in oral adenoid cystic carcinoma( OACC) and its relationship with clinicopathological features,and to explore the re-lationship between the expression of Ki-67 and PTEN. Methods Forty cases of oral adenoid cystic carcinoma were collected from the pathological laboratory in our hospital. Another 15 cases of normal gland in patients with oral adenoid cystic carcinoma were selected as the control group. The expression of Ki-67 protein and PTEN in adenoid cystic carcinoma was detected by immunohistochemistry. Results The positive rate of Ki-67 protein in oral adenoid cystic carcinoma was 70%(28/40),which was significantly higher than that in the control group(2/15)(P<0. 05). The positive rate of PTEN in oral adenoid cystic carcinoma was 63%(25/40),which was signif-icantly higher than that in the control group 20%(3/15)(P <0. 05). They were associated with histological types,metastasis,lymph node metastasis and neural invasion,and not correlated with age,gender and tumor loca-tion. The expression of Ki-67 and PTEN in oral adenoid cystic carcinoma may have a significant correlation. Conclusion The expression of Ki-67 and PTEN in adenoid cystic carcinoma is high,and their occurrence and development in adenoid cystic carcinoma play an important role in the process of evolution and metastasis. Ki-67 and PTEN proteins may be markers of oral adenoid cystic carcinoma.

Objective:To evaluate the effects of a booster immunization with a candidate tetanus toxoid, reduced diphtheria toxoid and acellular pertussis combined vaccine (Tdap) in a rat model after primary vaccination with diphtheria, tetanus, acellular pertussis and Sabin strain inactivated poliovirus combined vaccine (DTacP-sIPV) or diphtheria, tetanus, acellular pertussis, inactivated poliovirus and haemophilus type b combined vaccine (DTacP-IPV/Hib) for further preclinical study.Methods:Wistar rats were randomly divided into three groups and respectively immunized with a self-developed DTacP-sIPV, a marketed DTacP-IPV/Hib and normal saline at 0, 1, and 2 months of age. Serum levels of antibody against each component in each group were detected before immunization and after each dose. A booster dose of the candidate Tdap was given 10 months after primary immunization. Serum levels of antibody against each component in each group were detected before, 1 month and 6 months after the booster immunization.Results:One month after three doses of primary immunization, the geometric mean titers (GMT, Log2) of antibodies against diphtheria toxoid (DT), tetanus toxoid (TT), pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN) in the DTacP-sIPV group were 17.41, 18.34, 18.11, 19.93 and 13.91, respectively, and the seroconversion rates of these components all reached 100%. Ten months after primary immunization, the GMTs of antibodies against DT, TT, PT, FHA and PRN decreased to 15.17, 14.26, 13.60, 14.51 and 10.39, respectively, and the seroconversion rates remained above 89%. One month after booster immunization, the GMTs of antibodies against DT, TT, PT and FHA in the DTacP-sIPV and DTacP-IPV/Hib groups were 16.49/17.26, 16.80/17.63, 16.70/17.74 and 18.48/19.26, respectively, and the seroconversion rates of these components all reached 100% with no significant difference between the two groups ( P>0.05). The GMTs of anti-PRN antibody in the DTacP-sIPV and DTacP-IPV/Hib groups were 13.07 and 11.00, and the seroconversion rates were 100% and 88%, which were higher in the DTacP-sIPV group than in the DTacP-IPV/Hib group ( P<0.05). Six months after booster immunization, the GMTs of antibodies against DT, TT, PT, FHA and PRN in the DTacP-sIPV and DTacP-IPV/Hib groups decreased to 15.74/14.87, 15.07/15.14, 14.84/15.73, 16.62/16.37 and 11.44/9.96, respectively, and the seroconversion rates remained above 88%. Conclusions:Booster vaccination with the candidate Tdap vaccine induces humoral immune response following primary immunization with DTacP-sIPV or DTacP-IPV/Hib in the Wistar rat model, while the antibody titer decreases with time.

AIM: To observe the clinical efficacy of 8-0 polypropylene scleral-sutured fixed intraocular lens(IOL)suspension implantation with the double knots technique in aphakic eyes.METHODS: Retrospective case series study. The data of 30 aphakic cases(31 eyes, 22 males)that underwent IOL suspension in our hospital from January 2021 to November 2022 were collected. The suspension of IOL(AcrySof IQ or Tecnis ZCB00)was performed by 8-0 polypropylene scleral-sutured with the double knots technique. The visual acuity, intraocular pressure(IOP), IOL position and complications with at least 6 mo of follow-up were observed.RESULTS: The mean preoperative uncorrected visual acuity(UCVA, LogMAR)and best-corrected visual acuity(BCVA, LogMAR)were 2.53±0.78 and 0.35±0.26, respectively, which were 0.58±0.26 and 0.36±0.27 at 6 mo postoperatively, respectively. And the differences in UCVA were statistically significant(t=15.408, P<0.01), whereas the difference in BCVA was not(t=-1.677, P=0.104). There were no intraoperative complications, with IOL position all centered, but 3 eyes had IOL tilt, 2 eyes had intraocular hypertension, 5 eyes had corneal edema, and 1 eye had suture exposure postoperatively. There were no complications such as hyphema, vitreous hemorrhage, macular edema, corneal endothelial decompensation, hypotony, choroidal detachment, retinal detachment, fulminant superior choroidal hemorrhage, endophthalmitis, or others.CONCLUSION: The 8-0 polypropylene scleral-sutured fixed intraocular lens suspension implantation with the double knots technique can improve the postoperative visual acuity of aphakic patients, and fewer complications, which is an option for the treatment of aphakia, dislocation of the lens and ligament abnormalities.
