Objective:To observe the influence of multi-disciplinary cooperation and optimization management mode on the negative situation and rehabilitation effect of patients with affective disorder after coronary heart disease and cerebrovascular disease.Methods:A total of 188 patients with emotional disorders caused by coronary heart disease and cerebrovascular disease from January 2017 to December 2018 to our hospital were selected. According to the random number method, 94 cases in the control group adopted the conventional management model, and 94 cases in the experimental group adopted the multidisciplinary collaborative optimization management model. The negative emotions [evaluated by Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS) ] scores before and after management, the coping style (Jalowies) scores, and quality of life [evaluated by World Health Organization Quality of Life-Brief (WHOQOL-BREF) ] scores were compared between the two groups. The clinical rehabilitation effect and satisfaction rate of related management between the two groups were compared.Results:There were no significant differences between the two groups before management of SAS scores, SDS scores, Jalowies scores, and WHOQOL-BREF quality of life scores ( P> 0.05). After management, the SAS scores and SDS scores of the two groups were significantly reduced, and the Jalowies scores and WHOQOL-BREF quality of life scores were significantly increased. After management, the SAS score and SDS score of the experimental group were 47.32±5.68, 49.93±6.49 and 54.95±6.59, 55.33±8.30 in the control group, the difference was significant between two groups ( t value was 8.503, 4.969, P<0.01). The Jalowies scores and WHOQOL-BREF scores of the experimental group were higher than those of the control group ( t value was -27.662--4.290, P<0.01). The total effective rate of rehabilitation in the experimental group was 98.94%(93/94), which was significantly higher than 90.43%(85/94) in the control group, the difference was statistically significant ( χ2 value was 6.760, P <0.05). The total satisfaction rate of the experimental group for management intervention was 100.00%(94/94), which was significantly higher than the total satisfaction rate of the control group, 91.49%(86/94), the difference was statistically significant ( χ2 value was 6.397, P <0.05). Conclusions:In the patients with affective disorder caused by coronary heart disease and cerebrovascular disease, multi-disciplinary cooperation and optimization management mode can significantly reduce the negative emotions of patients after management, improve the way of patients to deal with the disease, effectively improve the clinical rehabilitation effect and the quality of life of patients, improve the satisfaction rate of patients with management, shorten the distance between nurses and patients, and achieve ideal results.

Objective The aim of this study was to investigate the relationship between phosphotyrosine interac-tion domain containing 1 ( PID1 ) gene and variation in intramuscular fat ( IMF ) content and the possibility to generate transgenic animals by testicular injection .Methods Expression vector pIRES2-acGFP-PID1 carrying pig PID1 gene was incubated with transfection reagents and injected into the testes of male New Zealand rabbits .We examined the F1 genera-tion by fluorescence detection , PCR, Western blotting and measuring the IMF content .The F1 generation gave birth to the F2 generation.Then we examined the F2 generation through detecting the positive rate and the IMF content .Results The exogenous PID1 gene and fluorescent protein gene were expressed at different levels both in the F 1 generation and the F2 generation, and the positive rates were 35.88%and 34.33%, respectively.The IMF content was significantly elevated (P<0.05) in the transgenic positive individuals compared with the negative ones and the control group , and the PID1 protein expression was similarly higher .Conclusions The results of this study demonstrate that PID 1 gene affects intramuscular fat content significantly .Moreover, the results of our analysis provide further evidence that transgenic animals can be gener -ated by testicular injection , and the exogenous gene can be inherited steadily .

Pig copper zinc superoxide dismutase (CuZnSOD) is an important antioxidant enzyme. Some studies focused on the function of CuZnSOD gene, but the transcriptional regulation of the CuZnSOD gene is not yet fully elucidated. Therefore, the aims of the study were to determine the core promoter region and to explore its mechanism of transcriptional regulation. The 853 bp DNA sequence of 5'-flanking promoter was amplified by performing PCR. A series of CuZnSOD promoter fragments with gradually truncated 5'-end were produced by nested PCR and inserted into pGL3-Basic vector. The activities of the promoters were measured by the dual-luciferase assay system after transient transfection into the NIH/3T3 cells. The results demonstrated that there were 2 potential transcription start sites in the regions from initiation codon to -87 bp and -266 bp, respectively. The region from -383 bp to +67 bp in CuZnSOD gene promoter showed higher activity than other regions, and further deletion analysis demonstrated that the region from -75 bp to -32 bp contained an essential promoter sequence for pig CuZnSOD gene transcription. In addition, several potential transcription factor binding sites were predicted with bioinformatics method. These results suggest that these transcription factor binding sites may be involved in the transcriptional regulation of CuZnSOD gene.

Objective To explore the application value of minimally invasive surgery in the treatment of lumbar spinal tuberculosis, and to provide reference for clinical treatment of spinal tuberculosis. Methods Data of 252 cases of patients with lumbar spinal tuberculosis treated by conservative treatment in our hospital from January 2005 to December 2014 were retrospectively analyzed. Patients were divided into four groups on the basis of systemic application of antituberculosis chemotherapy. A total of 154 patients were given simple local chemotherapy of percutaneous placement of focus catheter (group A), 48 patients were received percutaneous perfusion drainage and local chemotherapy (group B), 32 patients underwent percutaneous puncture catheter debridement combined with local chemotherapy (group C), and 18 patients were given percutaneous debridement and internal fixation combined with local chemotherapy catheter (group D). Data of erythrocyte sedimentation rate (ESR), visual analogue scale (VAS), Oswestry disability index (ODI) score and the modified MacNab criteria were recorded before operation and at the end of the follow-up in four groups of patients. Results Of the 252 patients, 228 were followed up and 214 patients achieved clinical cure. The lost access were15 cases in group A, 5 cases in group B, 2 cases in group C and 2 cases in group D. The total rate of lost visit was 9.52%. The follow up duration ranged from 25-126 months. The mean duration of follow-up was 68(60, 76) months. A total 214 cases reached the standard of clinical cure. No complications (retrograde infection and cross infection) were found in all patients during treatment. ESR was statistically decreased to (7.26 ± 3.43) mm/1 h at the last follow-up (t=35.06, P=0.023) compared with that (44.96 ± 12.42) mm/1 h before operation. The VAS and ODI were 1.5(1, 3) and 30(25, 35)% at the last follow-up, which were significantly improved than those [7.5(7.0, 8.0) and 60(55, 65)%] before operation (Z=13.641 and 6.806, P<0.05). According to the improved MacNab criteria, the overall excellent and good rates for patients were 86.4%(197/228) at the last follow-up. Conclusion According to the stepped care and personalized treatment, patients of lumbar tuberculosis are preoperative comprehensive evaluated, and most patients can achieve long-term stability and a better clinical efficacy after interventional and minimally invasive treatment.

Objective To investigate the effect of norcantharidin on growth inhibition and induction of apoptosis of human rectal cancer Colo 320 cells. Methods Norcantharidin (NCTD) in different concentrations were added to rectal cancer Colo 320 cells. Morphological characteristics of apoptosis were observed using the light microscope and transmission electron microscope. The expressions of Bag-1 and Bcl-2 proteins were tested by Western blotting. The growth inhibition of Colo 320 cells on the cell cycle was observed by flow cytometry. Results The apoptosis morphological changes of Colo 320 cells were observed by the light microscope and transmission electron microscopy. Flow cytometry analysis showed that the cell count of G2/M phase in experimental group was higher than that in control group ( <0.05) but the cell counts of G0/G1 and S phases have decreased in experimental group after treatment with NCTD at the concentrations of 5μg/mL, 10μg/mL and 20 μg/mL, and presented dosage dependence relations. The expressions of Bag-1 and Bcl-2 proteins have decreased. Conclusion Norcantharidin has inhibitory effect on rectal cancer Colo 320 cells, and the effect may be related to the cell cycle arrest and apoptosis.

Background Nanoemulsions (NEs) is one of the most popular ophthalmic colloidal drug delivery system due to its long-term stability, low toxicity and irritancy, considerable capacity for solubilization of lipophilic drug molecules and great potential in bioavailability improvement.The cornea pathway is the main route of intraocular absorption after topical use of NEs.Though NEs possess numerous physiological and physicochemical advantages,the use of NEs cannot always obtain satisfactory results.Objective This study was to investigate the impacts of epithelium and stroma on the corneal permeation of topical ophthalmic terbinafine hydrochloride nanoemulsions (TH-NEs).Methods TH-NEs was prepared by the self-emulsification method.The size and Zeta potential of the oil droplets in the formulation were analyzed using a dynamic light-scattering particle size analyzer.The high performance liquid chromatography (HPLC) was used for the in vitro release study.Sixty New Zealand albino rabbits were randomly divided into intact cornea group and cornea epithelium debrided group.The cornea epithelium of the left eyes was debrided in the cornea epithelium debrided group.The TH-NEs were instilled into the lower conjunctival sac of left eyes.Six rabbits were executed from each group 15,30,60,120 and 240 minutes after dosing,respectively.The corneas were collected and analyzed by HPLC.The fluorescein diacetate (FDA) was used to label the TH-NEs.Two C57BL/6 mice with left cornea epithelium debrided and 2 normal mice were used for the fluorescence tracing study.The fluorescence distribution of FDA labeled TH-NEs was observed by a two-photon laser confocal scanning microscope 30 minutes and 60 minutes after single instillation.Results The average size and Zeta potential of the oil droplets were 51.37 nm and-0.232 7 mV respectively,and 0.482％ of encapsulated drugs was released from the TH-NEs after 12 hours.The peak concentrations of TH in the intact cornea and epithelium debrided cornea were (17.85 ± 2.79) μg/g and (4.40± 1.75) μg/g respectively, which occurred 15 minutes postdose.The drug concentrations in the intact cornea were significantly higher than that in the debrided cornea 15,30,60 and 120 minutes after dosing, with significant differences between them (t =9.998,8.658,6.903,7.576;all at P=0.000).The fluorescence was observed in the cornea epithelium when the cornea was intact.The fluorescence intensity in the superior layer of corneal epithelium was obviously higher than that in the deep layers of corneal epithelium 30 minutes and 60 minutes after dosing.No fluorescence was observed in the cornea stroma of both eyes.Conclusions The cornea epithelium is the main of absorption and distribution position of TH-NEs.The cornea stroma is the dominating permeation barrier for the intraocular transportation of the TH-NEs.The cornea stroma may stop the permeation of TH-NEs by molecular exclusion mechanism.
