OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.

AIM:To investigate the effect of insulin on vascular smooth muscle cells (VSMCs) proliferation and to evaluate the intracellular signaling pathways involved.METHODS:VSMCs separated from Sprague-Dawley rats were used in this study. The proliferation of VSMCs induced by insulin was assayed by [3H]-thymidin incorporation. The protein expression and activity of p-ERK1/2 were determined by immunblot and [?-32P]ATP incorporation.RESULTS:Insulin induced cell proliferation in a concentration-dependent manner. The proliferative effect of insulin on VSMCs was inhibited partly by LY294002 (48.8%),an inhibitor of PI-3 kinase,and the ERK1/2 inhibitor PD98059 (43.6%),respectively. Moreover,phosphorylation of ERK1/2 and activity of ERK1/2 induced by insulin were also inhibited partly by LY294002.CONCLUSION:PI-3 kinase and ERK1/2 are involved in insulin induced VSMCs proliferation.

Objective To study the difference in therapeutic effects and side effects of ibuprofen versus indomethacin for symptomatic patent ductus arteriosus (PDA) in the premature infants.Methods Meta analysis was used to qualitatively and quantitatively evaluate the data extracted from 6 public papers about comparative study of ibuprofen and indomethacin.Results The rate of ductal closure was similar with the two treatment regimes (intravenous ibuprofen and indomethacin).In side effects on PDA,the incidence of oliguria induced by ibuprofen was significantly lower than that of indomethacin though there were no difference in other side effects.Conclusions The efficacy of ibuprofen for the early treatment of PDA in preterm infants is similar with indomethacin,and has low incidence of oliguria.

BACKGROUND: Direct anterior minimum invasive surgery (DAMIS) total hip arthroplasty has been considered as the total hip arthroplasty that is most consistent with the minimally invasive standards. In theory, there is a low incidence of complications in the DAMIS total hip arthroplasty. However, because minimally invasive surgery demands high surgery skills, the incidence rate of complications is high in the early period of its learning curve. Lateral decubitus position DAMIS was considered to provide a better perspective, so that, the incidence of surgical complications may be reduced. OBJECTIVE: To explore the feasibility of lateral decubitus position DAMIS for total hip arthroplasty. METHODS: Totally 62 cases from the Department of Orthopedics, First Affiliated Hospital of Gannan Medical University between April 2013 and April 2016 were retrospectively analyzed, and randomly assigned to two groups: lateral decubitus position group (n=31) and supine position group (n=31). Incision length, operative time, intraoperative blood loss, acetabular cup angle, hospital stay, Harris scores, Visual Analogue Scale score, and SF-36 score were compared between the two groups. Complications at postoperative 1 year were recorded. RESULTS AND CONCLUSION: (1) Operative time was longer and intraoperative blood loss was more in the lateral decubitus position group than in the supine position group (P < 0.05). There were no statistically significant differences in incision length and hospital stay between the two groups (P > 0.05). (2) There were no significant differences in the incidence of postoperative complications between the two groups (P >0.05). (3) There were no significant differences in the anteversion and abduction angles of acetabular cup between the two groups (P > 0.05). (4) There were no significant differences in Harris hip score, Visual Analogue Scale score, and SF-36 the quality of life scores between the two groups before surgery and 1 year after surgery (P > 0.05). (5) In conclusion, DAMIS total hip arthroplasty can abandon special traction bed when patients are in lateral decubitus position. The short-term effects are the same with supine DAMIS total hip arthroplasty.

Interleukin-2 (IL-2) therapy often results in potentially life-threatening side effects including hypotension. However, the mechanism has not been completely elucidated. In order to determine whether IL-2 modifies vascular tone, we investigated the effect of IL-2 on rat thoracic aorta rings and the underlying mechanisms. Effects of IL-2 on the contraction of high KCl and phenylephrine (PE) preconstricted rat thoracic aorta with or without endothelium were determined by organ bath technique. To explore the mechanism, nitric oxide synthase inhibitor L-N(G)-nitroarginine methyl ester (L-NAME), guanylyl cyclase inhibitor methylene blue, and cyclooxygenase inhibitor indomethacin were used. IL-2 (10-1000 U/ml) caused concentration-dependent relaxation of aorta rings preconstricted with PE (10 micromol/L) in endothelium-intact rings, but had no effect on KCl (120 mmol/L) preconstricted rings. Removal of the endothelium, or pretreatment with L-NAME (0.1 mmol/L) or methylene blue (10 micromol/L) or indomethacin (10 micromol/L), inhibited the relaxation of IL-2. The results indicate that the relaxation by IL-2 in rat aorta ring is endothelium-dependent and is possibly mediated by the NO-guanylyl cyclase pathway and cyclooxygenase-dependent pathway.

OBJECTIVETo observe the protective effect of active fractions of Huanglian Jiedu Decoction (HJD) on primary cortical neuron injury after oxygen-glucose deprivation (OGD)/reperfusion (R) injury. Methods Using macroporous resin method, HJDFE30, HJDFE50, HJDFE75, and HJDFE95 with 30%, 50%, 75%, and 95% alcohol were respectively prepared. Then the content of active components in different HJD fractions was determined with reverse phase high-performance liquid chromatography (RP-HPLC). The OGD/R injury model was induced by sodium dithionite on primary cortical neurons in neonate rats. MTT assay was used to observe the effect of four fractions (HJDFE30, HJDFE50, HJDFE75, and HJDFE95) and seven index components of HJD on the neuron viability.

RESULTSRP-HPLC showed active component(s) contained in HJDFE30 was geniposide; baicalin, palmatine, berberine, and wogonside contained in HJDFE50; baicalin, berberine, baicalein, and wogonin contained in HJDFE75. The neuron viability was decreased after OGD for 20 min and reperfusion for 1 h, (P <0. 01), and significantly increased after administered with HJD, HJDFE30, HJDFE50, and HJDFE75 (P <0. 05, P <0. 01). Geniposide, baicalin, baicalein, palmatine, wogonside, and wogonin could increase the cortical neuron viability (P <0. 05, P <0. 01).

CONCLUSIONSHJDFE30, HJDFE50, and HJDFE75, as active fractions of HJD, had protective effect on primary cortical neuron injury after OGD/R. Furthermore, geniposide, baicalin, and baicalein were main active components of HJD.

Chinese medicinal formulae (CMF) were usually used in the clinics of traditional Chinese medicines (TCM), which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. However, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were usually neglected. The put-forward of integrative pharmacology provided a feasible approach to solve the problem of the fragmentation of TCM. For the past years, we applied the strategy of integrative pharmacology to study Yuanhu Zhitong prescription( YZP) systematically, and established two modes, chemical fingerprints-metabolism fingerprints-network targets and intestinal absorption-activity evaluation-data mining, to establish the interaction rule between the chemical composition and biological activity from multiple levels, such as the calculation and in vitro/vivo, which provided proof for the quality control, pharmacodynamic material basis and pharmacological action of YZP. In this paper, we summarized the related progresses of the research of YZP.
