Objective To investigate the effect of continuing nursing on elderly patients with high risk of pressure sores. Methods High-risk elderly patients with pressure sores healed in our hospital in January 2014 to December 2014 were divided into control group and observation group with 130 cases in each group by random number table. The control group received routine follow-up service, while the observation group were intervened by continuing nursing care. To observe the differences before and after the interventions in both groups on the patient's quality of life and the incidence of pressure sores. Results There was statistically significance on mental function scores (t=12.393, P=0.000), social function score (t=8.459, P=0.000) and overall quality of life score (t=12.750, P=0.000) between the two groups after the interventions. Meanwhile, there was no statistically significance on material life score (t =-1.913, P=0.057) and physical function score (t=-0.328, P=0.744). The difference of the re-occurrence of pressure sores in the two groups was statistically significant (χ2=35.96, P=0.000), either. Conclusions Continuing nursing intervention can obviously reduce the risk the re-occurrence of pressure sores on high-risk elderly patients, in particular to improve the quality of life aspects of mental function and social function in patients, meanwhile with no obvious improvement in that of material life and body functions.

Objective To study the effect of bromocriptine(BRC) on the activation of T lymphocyte stimulated by phytohemagglutinin(PHA).Methods After CD4+ T cell line Jurkat E6-1 cells were stimulated by PHA,prolactin(PRL) and BRC,respectively,the expression of linker for activation of T cells(LAT) and zeta-chain T cell receptor associated protein kinase 70 000(ZAP-70) mRNA of T lymphocytes were checked by RT-PCR.The expression of PRL mRNA of T lymphocytes was detected by Real time PCR.The expression of CD25(cluster of differentiation) as a marker of early activation on the surface of T lymphocytes was detected by flow cytometry,and the activation of nuclear factor-?B(NF-?B) was detected by luciferase reporter system.Results 1.BRC inhibited the expression of ZAP-70 as the common signal molecules both in the T lymphocyte activation pathway and PRL-prolactin-prolactin receptor(PRLR) signal transduction pathway,and decreased the expression of PRL mRNA produced by activation T lymphocytes.2.BRC enhanced the expression of LAT mRNA as another important signal molecular on the T lymphocytes and CD25 on the surface of the T lymphocytes.3.The activation of NF-?B of T lymphocytes was decreased.Conclusions BRC might inhibit the activation of T lymphocytes by inhibiting the expression of ZAP-70,the common signal molecules between T lymphocytes activation and PRL-PRL pathway,and PRL mRNA,the like-T lymphocyte growth factor.

OBJECTIVETo observe and evaluate objectively the clinical effect of Guilong Tongluo Capsule (GTC) in treating chronic inflammatory demyelinating polyneuropathy (CIDP).

METHODSSixty CIDP patients were equally randomized into two groups. The treated group was administered with GTC and prednisone, while the control group with prednisone alone. Changes before and after 3-month treatment in terms of muscle force, functional and sensory disturbance of extremities, as well as scoring by Activity of Daily Living Scale (ADL) and electromyogram (EMG) for nerve conduction velocity were observed and compared.

RESULTSThe total effective rate gained in the treated group and the control group was 90.0% (27/30) and 70.0% (21/30) respectively, showing significant difference between them (chi2 = 14.82, P < 0.01). The improvement in the treated group was superior to the control group in muscle force of lower limb, motive and sensory function of extremities, ADL scores and motive function of ulnar nerve (P < 0.05, P < 0.01).

CONCLUSIONThe curative effect of GTC combined with prednisone in treating CIDP was better than that of prednisone alone.

Objective To investigate the antiproliferation and induction differentiation of human gas- tric carcinoma which human gastric lower-differentiation mucinous carcinoma MGC-803 cells transplanted in- to nude mice by using rosiglitazone(ROS),and to preliminarily explore the mechanism of differentiation. Methods The mice were randomly divided into five groups:model,ATRA,ROS 25 mg?kg~(-1),ROS 50 mg/kg, ROS 100 mg/kg.After that the volumes were measured and inhibition rates were calculated.The cell cycle was detected by FCM.The protein expression level of Mucin SAC was detected by immunohistochemistry. Results The volume of tumor decreased significantly in ROS treatment groups,the differences had statistical significance compared with model group(P0.05).The xenograft tumors of ROS groups demonstrated the characteristics of differentiation.Xenograft tumor cells were arrested in G_0/G_1 phase,and the cells in S phase decreased significantly,and up-regulated Mucin SAC gene expression.Conclusion ROS could inhibit the growth of tumor,and the effect were dose-dependent with ROS.ROS could induce the differentiation of Xenograft tumor cells of gastric cancer.Its mechanism might be related to the inhibit of transition from G_1 to S phase,degrade the activity of proliferation,regulate the expres- sion of Mucin 5AC.

3T3-LI preadipocytes were induced to differentiate and 3T3-L1 adipocyte or preadipocytes were incubated with oleate or palmitate overnight.RT-PCR was used to measure adiponectin receptor(AdipoR)1 and AdipoR2 mRNA levels.The results showed that the AdipoRl and AdipoR2 expressions were differentiation- dependent.Oleate only suppressed AdipoR mRNA expression in preadipocyte but not in adipocyte.However,high concentration of palmitate reduced AdipoR mRNA expression in both 3T3-LI preadipocyte and adipocyte.

Professional terms are the key points in the teaching of pharmaceutical English.By taking the strategies of comparing amphibious words,analyzing morphemes,emphasizing on phonetics,providing study material in real context and strengthening review,the teaching of pharmaceutical vocabulary can be efficiently performed and interest in learning stimulated.

To explore the new method of discriminating Cistanche deserticola, Cynomorium songaricum and Orobanche pycnostachya by using PCR amplification of specific alleles. 30 samples of the different C. deserticola, 21 samples of C. songaricum and O. pycnostachya were collected. The total DNA of the samples were extracted, the ITS sequences from C. deserticola, C. songaricum and O. pycnostachya were amplified by PCR and sequenced unidirectionally. These sequences were aligned by using ClustulW. Specific primer was designed according to the ITS sequences of specific alleles, and PCR reaction system was optimized. Additionally, compare with the identification of specific PCR method and DNA sequence analysis method. The result showed that the 331 bp identification band for C. deserticola and the adulterants not amplified bands by a single PCR reaction, which showed good identification ability to the three species. PCR amplification of specific alleles can be used to identify C. deserticola, C. songaricum and O. pycnostachya successfully.

Objective To study the expression and change of neuropeptide substance P (SP) during the wound healing of deep partial thickness scalding in diabetic rats. Methods Eighty-four Wistar rats were randomly divided into diabetes mellitus group (n=42) and control group (n=42). Diabetic rat models were established by intraperitoneal injection of streptozotocin (STZ) in diabetes mellitus group, and those in control group were intraperitoneally injected with aseptic citrate buffer solution. Deep partial thickness scalding with diameter of 2 cm on the back were prepared in all the rats. The pre-scalding and post-scalding wound specimens of different time points were obtained, and the percentages of wound closure were calculated. The wound specimens were also obtained for immunohistological staining to compare the areas with positive staining of SP, and ELISA was employed to detect the expression of SP in the wound tissues. Results The percentage of wound closure was significantly lower in diabetes mellitus group than that in control group from 7 days post-scalding (P< 0.01). The areas with positive staining of SP in diabetes mellitus group were much smaller than those in control group at different time points, which was most significant on the seventh day post-scalding[(1 350.93±99.28) μm2 vs(1 715.86± 103.41) μm2](P < 0.01). The expression of SP in the wound tissues was significantly lower in diabetes mellitus group than that in control group at different time points, which was most significant on the seventh day post-scalding[(114.04±9.96) vs(143.39±8.94)](P<0.01). Conclusion The significantly lower expression of SP in wound site may be one of the causes of delayed wound healing in diabetic rats.
