BACKGROUND: At present, studies concerning human umbilical cord blood mesenchymal stem cells (UCB-MSCs) transplantation for repair of rat spinal cord injury, brain tumor, and myocardial infarction have been reported, and studies that human UCB-MSCs were induced differentiation into osteogenic cells under certain conditions have also been reported at home and abroad. But application of UCB-MSCs transplantation in the treatment of osteonecrosis of animals has not yet been reported. OBJECTIVE: To observe the repair results of recombinant lentivirus vector tracing enhanced green fluorescent protein (EGFP)-transfected UCB-MSCs transplantation in treatment of ischemic necrosis of the femoral head in rabbits. METHODS: Bone morphogenetic protein-2 gene plasmid, recombinant lentivirus vector carrying EGFP and UCB-MSCs were co-cultured. Rabbit models of femoral head defects were made and randomly divided into 3 groups. There was no treatment in the normal group, control group with bone defects and experimental bone defects filled with UCB-MSCs tracing transfected by recombinant lentivirus vector carrying EGFP. At 4 and 8 weeks after treatment, the imaging and histological of the femoral head were observed.RESULTS AND CONCLUSION: Imaging and histology results showed that there were osteogenic response and new bone formation in the experimental group at 4 weeks, and the bone defects were basically repaired at 8 weeks after treatment. In the control group, the bone defects filled with fibrous connective tissue fiber connective tissues at 4 weeks, and the osteosclerosis could be found surrounding femoral head, bone defects filled with fibrous connective tissue fibers and bone trabecula distributed disorderly. The recombinant lentivirus vector tracing EGFP-transfected into UCB-MSCs has strong effects bone conduction and can repair ischemic necrosis of the femoral head.

To study the implementation of the epidemic prevention by the authorities of the concession and late Qing dynasty through investigation of the prevention and treatment of pestilence in Shanghai from 1872 to 1911, this paper analyzes the issues concerning municipal administration, inspection and disinfection, food sanitation, vaccination, regulatory legislation and health promotion, etc. The experiences are summarized in the study. The lessons drawn from what the concession authority did to prevent pestilence imply that the implementation of health promotion should be carried out according to the variation of the time, location and population, and that traditional Chinese medicine should be involved in the prevention and treatment of pestilence.

We reported a case of trisomy 18 with Abernethy malformation diagnosed by prenatal ultrasound, which was confirmed by chromosome karyotyping after cordocentesis and fetal autopsy. At 24 gestational weeks, fetal sonography revealed a fetus with multiple malformations (cleft lip/cleft palate of left side, left radial dysplasia, hooked hands, bilateral pes valgus, ventricular septal defect, and congenital extrahepatic portocaval shunt), which was diagnosed as trisomy 18 syndrome with Abernethy malformation. The fetus's karyotype was 47, XX+18.

Objective:To explore the value of current indications for fetal pulmonary valvuloplasty (FPV) by summarizing the postnatal diagnosis, treatment, and prognosis of fetuses with pulmonary atresia with intact ventricular septum (PA/IVS) and right ventricular hypoplasia (RVH).Methods:This prospective study was conducted at the Heart Center of Women and Children's Hospital, Qingdao University from September 2018 to March 2021, which included pregnant women who were (1) with fetal PA/IVS and RVH; (2) unable to receive FPV due to fetal position or gestational age despite the indications; (3) given integrated pre- and postnatal management. Prenatal fetal echocardiography assessment, postnatal diagnosis, treatment, and follow-up were summarized using Wilcoxon matched-pair signed-rank test.Results:A total of 35 singleton pregnant women were diagnosed with fetal PA/IVS and RVH by ultrasonic cardiogram and admitted during the study period. Among the 28 fetuses meeting the FPV indications, 18 underwent FPV, while the other 10 did not due to inappropriate fetal position or gestational age. After excluding four terminated pregnancies, the rest six cases were enrolled. The median gestational age at the initial prenatal fetal echocardiography diagnosis was 28.9 weeks (28.3-30.4 weeks). Compared with the initial evaluation, the fetal right ventricular to left ventricular length/diameter ratio [0.8 (0.6-0.9) vs 0.6 (0.5-0.8)] and tricuspid regurgitation velocity [4.7 m/s (3.2-5.1 m/s) vs 4.1 m/s (3.3-4.8 m/s)] were increased, while tricuspid valve Z value [－0.8(－1.6-0.8) vs 0.4 (－0.3-1.9)] and single-ventricular predictive score [0.5 (0.0-2.0) vs 2.0 (1.0-3.0)] were decreased when re-evaluated six weeks later ( T were－2.21, 2.00,－2.20, and 2.00; all P<0.05). All of the six fetuses were born alive with a median gestational age of 38.9 weeks (37.3-40.1 weeks). The median weight was 3 425 g (3 100-4 160) g after being transferred to cardiac intensive care unit. The median age was 12.5 d (0.0-20.0 d) at the first surgical intervention. The median follow-up duration was 15 months (11.8-18.5 months). At initial diagnosis, the single-ventricular predictive score was 1-2 points in four fetuses, and =3 points in two fetuses. There was no death during follow-up. Four patients achieved anatomical biventricular circulation, one achieved clinical biventricular circulation, and one still needed further follow-up, with single-ventricular predictive score at initial diagnosis of 1-3, 3, and 2 points, respectively. Conclusions:The prognosis is good in fetuses with PA/IVS and RVH who have FPV indications but do not receive intrauterine intervention, which suggests that the current FPV indications may be too broad, and a more suitable FPV indication need to be further explored given the difficulty of implementing FPV.

Purpose: Cavernous nerve injury induced erectile dysfunction (ED) is a refractory complication with high incidence in person under radical prostatectomy. Studies have shown that relaxin-2 (RLX-2) plays a vital role of endothelial protection, vasodilation, anti-fibrosis and neuroprotection in a variety of diseases. However, whether penile cavernous erection can benefit from RLX-2 remains unknown. The purpose of the experiment was to explore the effects of RLX-2 on ED in the rat suffering with bilateral cavernous nerve injury (BCNI). Materials and Methods: The rats were divided into three groups: Sham group was underwent sham operation, BCNI+RLX group or BCNI group was underwent bilateral cavernous nerve crush and then randomly treated with RLX-2 (0.4 mg/kg/d) or saline by continuous administration using a subcutaneously implanted micro pump for 4 weeks respectively. Then, erectile function was evaluated by electrical stimulation of cavernous nerves. Cavernous nerves and penile tissues and were collected for histological evaluation. Results: Erectile function of rats with BCNI was partially improved after RLX-2 treatment. The BCNI group had lower expression of relaxin family peptide receptor (RXFP) 1, p-AKT/AKT, p-eNOS/eNOS ratios than sham operation rats, but RLX-2 could partially reversed these changes. Histologically, the BCNI+RLX group had a significant effect on preservation of neurofilament, neuronal glial antigen 2 of penile tissue and nNOS of cavernous nerves when compared with BCNI group. RLX-2 could inhibited the lever of BCNI induced corporal fibrosis and apoptosis via regulating TGFβ1-Smad2/3-CTGF pathway and the expression of Bax/Bcl-2 ratio, caspase3. Conclusions RLX-2 could improve erectile function of BCNI rats by protecting cavernous nerve and endothelial function and suppressing corporal fibrosis and apoptosis via RXFP1 and AKT/eNOS pathway. Our findings may provide a promising treatment for refractory BCNI induced ED.

Objective: To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. Methods: From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. Results: A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (P=0.016), and perceived seriousness was decreased by 0.73 (P=0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, P=0.001) and diastolic blood pressure was decreased by 4.07 mmHg (P=0.014), respectively. The β (95%CI) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (P<0.05). Conclusion Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.
