ObjectiveTo study the effect of early rehabilitation nursing on secondary disturbance in hemiplegics after stroke.Methods140 patients were randomly divided into two groups , rehabilitation nursing group (70 cases) and control group (70 cases). Patients in the rehabilitation nursing group were given clinical treatment and regularly convalescent nursing, while those in control group were given clinical treatment and unguided self-training. Evaluation was performed in pre-treatment and 12 weeks post-treatment respectively.ResultsSecondary disturbance rate in the rehabilitation nursing group was significant lower than that in the control group (P<0.01). The motor scores and ADL scores measured by Barthel Index in both groups raised after 12 weeks treatment, but the scores in the early rehabilitation nursing group were obviously superior to those in the control group (P<0.01).ConclusionEarly rehabilitation nursing for hemiplegics afte sroke may prevent or lessen the secondary disturbance, as well as obviously improve motor function of the limbs and ADL.

Background Establising the culture model of Müller cells for obtaining the highly putified target cells is essential for the study about the physiology and pathology of retinal Müller cells. The exsiting purifing method for culturing Müller cells is dissatisfactory. Objective This study was to establish a method to obtain high purifing Müller cells. Methods The retina from 5 clean newborn SD rats were isolated and digested by 0. 01% trypsin and cultured in DMEM containing 10% fetal bovine serum. The cellular suspension was then prepared,and the target cells were screened using flow cytometry based on the size and the quantity of cells. Cultured and passaged cells were identified by transmission electron microscope and light microscope. Immunocytochemistry was used to detecte the expression of GFAP in cultured cells for the determination of type and purity of the cells. Results The cells showed the similar shape to retinal Müller cells after primarily culture with the large volume, and some small other types of cells could been seen. The growth of cells was quickly 3 weeks later. The fibroblasts were removed using sticking-wall by steps,and neurons were eliminated following passage. Aboundent of cellular organs were seen under the transmission electron microscope. The positive response rate of the cells for CFAP was 100%. Conclution Flow cytometry offer a rapid and feasible approach for purifying Muller cell and it builds the foundation for further study about Müller cells.

ObjectiveTo explore the relationship among 25-hydroxyvitamin D,serum calcium,calcium-sensing receptor,and breast cancer. Methods The expressions of calcium-sensing receptor (CaSR) in primary breast cancer,breast benign tumors,and normal breast tissue beside tumors were determined by immunohistochemistry S-P method as well as the concentration of serum 25 (OH) D and serum calcium in breast cancer and breast benign tumors by Enzyme-linked immunosorbent assay (ELISA),Tribromoarsenazo Ⅲ method.ResultsSerum 25 (OH) D level of breast cancer was significantly lower than the breast benign tumors [ (34.13 ± 14.14) nmol/L vs (50.29 ± 25.65 ) nmol/L,t =2.870,P =0.001 ].Serum level of 25 ( OH ) D in lymph node metastasis positive patient was lower than that in negative group [ (30.8 ± 9.71 ) nmol/L vs (43.7 ± 23.59) nmol/L,t =2.467,P =0.021 ].The positive expression of CaSR in breast cancer(88.9％ )was higher than breast benign tumors(60％,x2 =6.717,P ＜ 0.01 ) and normal breast tissue beside tumors (60％,x2 =5.628,P ＜ 0.05 ).ConclusionsConcentration of serum 25 (OH)D and expression of calcium-sensing receptor in the tissues may be associated with occurrence,development and prognosis of breast cancer.

Objective To investigate the effect of hepatitis B virus (HBV) on the immune function of natural killer (NK) cells.Methods Healthy human peripheral blood-derived NK cells were cultured alone,or co-cultured with plasmacytoid dendritic cell (pDC) (NK∶ pDC=5∶1) for 48 h with or without HepG 2.2.15-derived HBV.Cell activation was assessed by flow cytometry.The specific enzyme linked immunosorbent assay (ELISA) and intracellular cytokine staining (ICS) were used to determine the cytokine production,the cytotoxic effect of NK cells on the carboxyfluorescein diacetate succinimidyl ester (CFSE)-labelled K562 target cells as well as the granzyme and perforin levels in NK cells.Paired results were analysed using Wilcoxon signed rank test.Results HBV did not affect interleukin (IL)-12/IL-18 and IL-18/interferon α (IFNα)-induced interferon γ (IFNγ) production by NK cells when NK cells were cultured alone (both P＞0.05).However,HBV significantly inhibited pDC-induced IFNγ production by NK cells (146.1 pg/mL),while CpG enhanced pDC-induced IFNγ production by NK cells significantly (1135.4 pg/mL,P=0.0005).HBV did not affect pDC-induced NK cell activation and cytotoxicity to K562 target cells as well as intracellular granzyme and perforin levels.ConclusionHBV does not activate but inhibits pDC-induced NK cell function,which may contribute to the persistence of HBV infection.

This study aimed to explore the outcomes of progestin-primed ovarian stimulation protocol (PPOS) in aged infertile women who failed to get pregnant in the first IVF/ICSI-ET cycles with GnRH-a long protocol.A self-controlled study was conducted to retrospectively investigate the clinical outcomes of 104 aged infertile patients who didn't get pregnant in the first IVF/ICSI-ET treatment by stimulating with GnRH-a long protocol (non-PPOS group),and underwent PPOS protocol (PPOS group) in the second cycle between January 2016 and December 2016 in the Center for Reproductive Medicine,Renmin Hospital of Wuhan University.The primary outcomes included clinical pregnancy rate of frozen-thawed embryos transfer (FET) in PPOS group,and good-quality embryo rate in both groups.The secondary outcomes were fertilization rate,egg utilization rate and cycle cancellation rate.The results showed that there were no significant differences in basal follicle stimulating hormone (bFSH),antral follicle count (AFC),duration and total dosage of gonadotropin (Gn),number of oocytes retrieved,intracytoplasmic sperm injection (ICSI) rate,fertilization rate,and cycle cancellation rate between the two groups (P＞0.05).However,the oocyte utilization rate and good-quality embryo rate in PPOS group were significantly higher than those in non-PPOS group (P＜0.05).By the end of April 2017,62 FET cycles were conducted in PPOS group.The clinical pregnancy rate and embryo implantation rate were 22.58％ and 12.70％,respectively.In conclusion,PPOS protocol may provide better clinical outcomes by improving the oocyte utilization rate and good-quality embryo rate for aged infertile patients who failed to get pregnant in the first IVF/ICSI-ET cycles.

AlM:To discuss the protective effect ofα-mangostin on retinal light damage in mice.METHODS:Totally 30 Balb/c mice, aged 6~8wk, were randomly divided into the control group, light-exposure group and α-mangostin group. Every group contained 10 mice. Mice of α-mangostin group were treated with alpha-mangostin at the dose of 30mg/( kg · d ) body weight by intragastric administration daily for 7d, and then exposed to white light at the 5th d. The light-exposure group and α-mangostin group were exposed to 5 000 ± 200lx white light-emmiting diodes (LEDs) for continuously 1h to establish the mice model of retinal light damage. Flash -electroretinograme was recorded 72h after light exposure. The changes in retinal morphology of mice were observed by light microscopy. Retinas were extracted to detect the malondialdhyde ( MDA ) content change of the retinal homogenate.RESULTS: Flash-electroretinogram ( F-ERG ) showed that retinal dysfunction was less severe in α-mangostin group than in light-exposure group ( P<0. 05 ). Light microscopy test showed that retina structural damage was less severe in α-mangostin group than in light-exposure group (P<0. 05). The level of MDA in retinal tissue of α-mangostin group was significantly lower when compared with light-exposure group (P<0. 05).CONCLUSlON: α-mangostin inhibits lipid peroxidation induced by light damage and protect retina against light damage.
