Objective: To investigate the effect of combining acupuncture and auricular point sticking on heart rate variability (HRV) in patients with post-stroke depression (PSD). Methods: A total of 80 cases with PSD were randomized into a treatment group and a control group. The control group was intervened by oral administration of paroxetine hydrochloride, whereas the treatment group received acupuncture plus auricular point sticking base on the same oral administration. The Hamilton depression rating scale (HAMD) and HRV were measured before and after treatment in both groups. Results: The individual and global scores of HAMD significantly dropped after 8 weeks of treatment in both groups (all P<0.05). In the treatment group, anxiety/somatization factor, sleep disturbance, hopelessness factor, cognition factor and global score were significantly different from those in the control group (all P<0.05). The 24 h standard deviation of all normal-to-normal R-R interval (SDNN), standard deviation of 5-minute average of normal R-R intervals (SDANN), root mean square of successive differences (RMSSD), percent of differences between adjacent normal R-R intervals >50 ms (PNN50) and high frequency (HF) were increased while low frequency (LF) and LF/HF decreased significantly after 8 weeks of treatment in both groups (P<0.05). All items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Combining acupuncture and auricular point sticking can enhance the conventional medical treatment for HRV in patients with PSD.

Bone marrow mesenchymal stem cells (MSCs), multipotent stem cells, can replicate as undifferentiated cells and have the potential to differentiate into different lineages of mesenchymal tissues, including bone, cartilage,endothelial, neural, smooth muscle, skeletal myoblasts, and cardiac myocyte cells. The ischemia-induced death of cardiomyocytes results in scar formation and reduced contractility of the ventricle. Several preclinical and clinical studies have supported the notion that MSCs therapy may be used for cardiac regeneration.When transplanted into the infracted heart, MSCs prevent deleterious remodeling and improve recovery, but the mechanism is not clear. In this work,we review evidence and new prospects that support the use of MSCs in cardiomyoplasty.

To study the protective effect and the mechanism of asiatic acid (AA) from Potentilla chinensis on alcohol hepatic injury in rats. Male Wistar rats were randomly divided into six groups: the normal control group, the AA control group (8 mg · kg(-1) AA), the model group (5.0-9.0 g · kg(-1) alcohol) and high, medium and low-dose AA-treated groups (alcohol + 8, 4, 2 mg · kg(-1) AA). Each group was orally administered with the corresponding drugs once a day for 24 weeks. Approximately 1. 5 hours after the final administration, all rats were killed, and their blood samples and hepatic tissues were collected. The AST and ALT in rat serum and the contents of MPO, TNF-α, IL-1β, SOD, GSH-Px, GSH-Rd and MDA in hepatic tissues were detected. The expressions of NF-κB, TLR4, CD14, MyD88, TRIF and protein expression in hepatic tissues were measured by western blot. The pathological changes in liver tissues were observed by histological examination. The results showed that compared with the model group, the AA-treated groups showed significant decreases in serum ALT, AST and MDA and increases in the activities of SOD, GSH-Px, GSH-Rd and MPO. Moreover, AA markedly inhibited the expressions of TNF-α, IL-1β, TLR4, CD14, MyD88 and NF-κB. The histological examination showed alleviated hepatic issue ijury to varying degrees. In short, asiatic acid (AA) from P. chinensis could protect alcohol-induced hepatic injury in rats. Its mechanism may be related to the inhibition of NF-κB inactivation and the reduction of inflammatory response.

OBJECTIVETo explore the relation of the anogenital distance (AGD) with cryptorchidism in male newborns.

METHODSThis study included 350 male infants delivered in two community hospitals between September 2013 and September 2014. Within 24 hours after birth, a pediatric surgeon measured the AGD of the neonates and determined whether they had cryptorchidism. According to the testicular position, we divided the undescended testes into three types: upper scrotal, inguinal, and non-palpable.

RESULTSTotally 39 cases of cryptorchidism were found in the 350 newborns. The AGD of the cryptorchidism infants was significantly shorter than that of the normal neonates ([2.01 ± 0.22] vs [2.35 ± 0.19] cm, P < 0.01), and statistically significant differences remained even when preterm and low birth-weight infants were excluded ([2.32 ± 0.14] vs [2.06 ± 0.19] cm; (2.37 ± 0.17) cm vs (2.12 ± 0.12) cm, all P < 0.01). The newborns with higher-position cryptorchidism had a shorter AGD, though with no significant difference (F = 0.434, P > 0.05). No significant differences were observed in the AGD between unilateral and bilateral cryptorchidism ([1.96 ± 0.13] vs [2.02 ± 0.17] cm, P > 0.05).

CONCLUSIONShorter AGD is associated with a higher incidence of cryptorchidism in male newborns. AGD could serve as a potential biomarker for disruption of androgen action during the male programming window period.

OBJECTIVETo investigate the infection rate and genotypes of Mycoplasma pneumoniae (MP) by examining bronchoalveolar lavage fluid from children with community acquired pneumonia (CAP).

METHODSPolymerase chain reaction (PCR) was used for detecting MP in bronchoalveolar lavage fluid from 220 children hospitalized with CAP, and the accuracy was confirmed by quantitative real-time PCR. Positive samples were digested with HaeⅡ and Hae Ⅲ and compared with standard strain to analyze the genotypes of MP from positive samples. The accuracy of genotyping was confirmed by sequencing the amplified products of some randomly selected positive samples.

RESULTSThe positive rate of MP in 220 samples was 55.0% (121/220). MP infection occurred mostly in preschool and school-age children (63.5%, 101/159), and the lowest positive rate was seen in children aged under 6 months (20%, 1/5). The positive rate showed no significant differences between sexes and between seasons. Sixty randomly selected MP-positive samples showed a genotype of P1 type 1 after restriction digestion, which was further confirmed by sequencing of 4 samples.

CONCLUSIONSMP is one of the main pathogens of pneumonia in children, and the MP infection rate is significantly correlated with age. The dominant genotype of MP in children is P1 type 1.

OBJECTIVETo investigate non-invasive prenatal genetic diagnosis of beta-thalassaemia using a single fetal nucleated erythrocyte (NRBC) from maternal blood by comparing with the genotype obtained from chorionic villus or amniocytes, and to evaluate the diagnostic results in reliability and feasibility of this method.

METHODSMaternal blood samples were obtained from 28 pregnant women at risk of beta thalassaemia during 9 - 34 weeks of gestation. NRBCs in maternal blood were enriched by single density gradient separation, stained with benzidine, and then collected by micromanipulation individually. After primer extension preamplification (PEP) of the entire genome from each single NRBC, short tandem repeat (STR) genotype was analyzed after further amplification of this gene. Single NRBC was tested individually to identify if it was fetal or maternal in origin by STR genotype of NRBC and its corresponding parents. beta-globin DNA fragments were amplified with nested-PCR using PEP product of a single fetal NRBC that was determined to be fetal in origin. Fetal beta-globin genotypes were analyzed by reverse dot-blot hybridization (RDB), the accuracy was evaluated by comparing with genotype which had been determined on DNA obtained from chorionic villus (CVS) or amniocytes.

RESULTSA total of 298 NRBCs were found in all of 28 pregnant women at a range of 4 to 13 per 5 ml venous blood. After PEP, about 43.6% of NRBCs were determined to be fetal in origin by STR typing. Using PEP product of a single fetal NRBC as template, beta-globin DNA fragment was examined on agarose gel after nested-PCR, amplification efficiency was 90.8% (118/130). Fetal beta-globin genotypes were achieved successfully in all cases with RDB. Comparing with the genotypes which were obtained from CVS or amniocytes, the rate of diagnostic accuracy was 85.7% (24/28).

CONCLUSIONSPEP technique and STR genotype analysis provide effective method for identification of single nucleated erythrocyte from maternal blood in origin. With the techniques PEP and RDB, fetal beta-globin genetic diagnosis was achieved using a single fetal NRBC from maternal blood. The method had a high accuracy and reliability in diagnosis. It may become an optional approach to non-invasive prenatal diagnosis of beta-thalassemia.
