OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.

METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.

RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.

Pulmonary fibrosis is a chronic and progressive lung disease that poses a threat to human health. Current treatment options are limited, highlighting the urgent need for more effective therapeutic strategies. Tetrandrine (TET), a bis-benzylisoquinoline alkaloid extracted from Stephania tetrandra, has been known for its anti-inflammatory and anti-fibrotic effects, but its specific mechanisms remain unclear. This study investigated the anti-fibrotic effects of TET in a chronic model of pulmonary fibrosis, aiming to delineate the molecular mechanisms underlying TET-mediated inhibition of fibroblast activation. The results showed that TET significantly alleviated the pathological changes in a murine model of multiple bleomycin-induced pulmonary fibrosis and effectively inhibited TGF-β1-induced fibroblast activation. Mechanistically, TET predominantly inhibited the TGF-β/SMAD signaling pathway and diminished intracellular reactive oxygen species (ROS) levels. Utilizing CRISPR-Cas9 library screening, we identified that angiotensin II type 1 receptor associated protein (AGTRAP) and membrane palmitoylated protein 6 (MPP6) played important roles in TET's suppressive impact of ROS levels, with the knockout of two genes attenuating TET's antifibrotic activity. All animal treatment procedures were approved according to the Committee on the Ethics of Animal Experiments of the Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (IMB-20230406D507). This research not only elucidates the pharmacological mechanism of TET but also provides a novel therapeutic avenue for the treatment of pulmonary fibrosis.

Objective:To find out predictors of the testicular ischemia caused by incarcerated inguinal hernia and evaluate the ischemic injury of the testis more accurately, which can indicate testicle exploration in time or prevent unnecessary testicle exploration.Methods:Pediatric patients (median: 9 months) undergoing operation of unilateral incarcerated inguinal hernia and ipsilateral testicular exploration from 1 Jul. 2013 to 30 Jun. 2019 were retrospectively investigated. Age at surgery, incarcerate duration, degree of intestinal and testicular injury, times of manual reduction and preoperative ultrasound data were collected. Statistical analysis was performed by SAS 9.4 (Copyright ? 2016 SAS Institute Inc.Cary, NC, USA) .Results:460 patients (median: 9 months) , of which 57 (12.39%) (median: 1.4 months, interquartile range 0.8-10.7 months) had severe testicular injury, and their average incarceration time was (23.9±9.3) h. Univariate logistic regression revealed that increased times of manual reduction, ultrasound scores, incarcerate duration and degree of intestinal injury were positively correlated with the degree of testicular ischemia, while age at surgery was negatively correlated with the degree of testicular ischemia ( P<0.05) . A model for calculating the probability of severe testicular ischemia injury was established: P= through multivariate analysis with backward stepwise logistic regression and 10-fold cross-validation was used for preliminary verification of the model. Conclusion:This study provides a relative reliable model to predict the risk of irreversible testicular ischemia due to incarcerated inguinal hernia using readily available clinical characteristics in young pediatrics with testicular ischemia.

OBJECTIVETo observe the long-term effect of plasma-derived HBV vaccine.

METHODSThe effect of a plasma-derived HBV vaccine which was given to children born in 1986 in Huangpu district in Shanghai were followed up once every two years and testing for HBsAg, anti-HBs and anti-HBc was carried out. Compared to background results from cross-sectional survey of hepatitis B virus in 1984 and 1985 (as internal control) as well as finding of survey targeted in non-plasma-derived HBV vaccine of children born in the same time in the nearby area from results investigated in 1991 (as external control), positive rate was calculated to assess the effect of protection.

RESULTSThe population immunized was followed up for 23 years and 5993 blood samples were collected. During the period of follow-up, the positive rate of anti-HBs decreased from 89.01% to 18.77% and the average level was 40.39%. The average positive rate of anti-HBc was 1.87%. The annual positive rate fluctuated around the average level. HBsAg positive rate remained less than 1.00% (0.46% - 0.98%), with an average of 0.62% (37/5993). Ranges of positive efficacy were from 81.37% to 95.78% against background control and 72.76% against external control.

CONCLUSIONThe plasma-derived HBV vaccine showed a good long-term protective effect and there was no need for boosting the immunization 23 years later.
