Objective To investigate the effect of exercise on calcium modulin in myocardial sarcoplasmic re-ticulum of animal type 1 diabetes model in rat. Methods A total of 40 Spragne-Dawley rats were randomly dividedinto 4 groups : a normal control group, an exercise training group, a diabetes group and a diabetes plus exercise-traininggroup. At the end of 4- week-exercise training after the establishment of the diabetes model by intraperitoncal injectionof sterptozotocin, the animals were sacrificed and the level of blood glucose, insulin, blood fat and glycosylated serumprotein were tested. The gene expression of calcium modulin proteins was measured by reverse transcription-polymerasechain reaction, and the Western blotting technique was used to measure the protein of sarcoplasmic endoplasmic reticu-lure Ca<'2+> -ATPase (SERCA2) and phaspholamban (PLB). Results The level of biochemical indicator of exercisegroup is not affected when comparing with that of the control group, but significantly changed in diabetic group ( P <0. 01 ) ; The level of blood glucose, insulin, blood fat and glycosylated serum protein were ameliorated in diabetic rats inthe exercise training group. No significant changes in mRNA level of SERCA2, PLB and ryanodine receptor type 2(RYR2) were observed between control and diabetic group, the same to protein expression of SERCA2 and PLB. Butexpression of calcium modulin mRNA was significantly increased in exercise group and diabetic rats in the exercisetraining group comparing with that of the control and diabetic groups ( P < 0.01 ), the same to protein expression ofSERCA2 and PLB. Conclusion Exercise exerted good protective effects on the myocardial injury with 1 type diabetesrat, which might attribute to the upregnlated expression of SERCA2, PLB and RYR2 in diabetic rat heart.

Objective To observe the preventive efficacy and safety of dexmedetomidine with parecoxib sodium on the patients with postoperative hyperalgesia induced by remifentanil. Methods A total of 100 female patients undergoing elective surgery under general anesthesia were as-signed into four groups according to the table of random number:the control group (group C),the parecoxib sodium group (group P),the dexmedetomidine group (group D)and the parecoxib sodium combined with the dexmedetomidine group (group DP).The vital signs were monitored and the total intravenous anesthesia was performed.All the patients were give intravenous injection of 0.2μg·kg-1 ·min-1 remifentanil and 4-12 mg·kg-1 ·h-1 propofol to maintain the anesthesia.Patients in group P were given 40 mg parecoxib sodium 30 minutes before the end of the operation.Patients in group D were give intravenous injection of 0.6μg·kg-1 ·min-1 dexmedetomidine consistently till 30 min before the end of the operation.Patients in group DP were given 0.6 μg·kg-1 ·min-1 till 30 min before the end of the operation and were given 40 mg parecoxib sodium.The VAS scores were re-corded at 1,2,6,12,24 hours.The cases of agitation,rigors,nausea and vomiting and increasing of analgesics were recorded.Results The postoperative VAS scores in group P,group D and group DP were significantly lower than group C(P <0.05).The postoperative VAS scores in group DP were significantly lower in group P and group D (P<0.05).Cases of agitation and rigors in group D and group DP were less than group C(P <0.05).The increasing of analgesics in group DP was much higher than other groups(P<0.05).Conclusion After induced,patients were given intravenous in-jection of 0.6 μg·kg-1 ·min-1 dexmedetoniding consistently till 30 min before the end of the opera-tion were given 40 mg parecoxib sodium can effectively prevent hyperalgesia after remifentanil anes-thesia without significant increase in revival time and obtain a better sedation.

Herpes simplex virus (HSV), a member of the Herpesviridae family, is a significant human pathogen that results in mucocutaneous lesions in the oral cavity or genital infections. Acyclovir (ACV) and related nucleoside analogues can successfully treat HSV infections, but the emergence of drug resistance to ACV has created a barrier for the treatment of HSV infections, especially in immunocompromised patients. There is an urgent need to explore new and effective tactics to circumvent drug resistance to HSV. This review summarises the current strategies in the development of new targets (the DNA helicase/primase (H/P) complex), new types of molecules (nature products) and new antiviral mechanisms (lethal mutagenesis of Janus-type nucleosides) to fight the drug resistance of HSV.

Objective:To prepare a virus-like particle (VLP),containing Hepatitis B virus core antigen (HBcAg) and N-terminal peptides of the L2 protein of human papilloma virus (HPV),and investigate the immunogenicity of the VLP in mice and the protection against different strains of HPV .Methods:A fusion gene was synthesized to insert a DNA fragment ,coding for the N-terminal epitopes of the L2 protein of HPV16,into the HBcAg coding sequence;HBc-L2 fusion protein was highly expressed in E.coli using the pET9a and BL21(DE3) expression system;the purified fusion protein was used to immunize BALB/c mice and antibody titers against the L2 epitopes in mouse sera were determined by indirect ELISA;the levels of neutralizing antibodies against both HPV 16 and 18 were also analyzed.Results:HBc-L2 fusion protein was expressed in E.coli and purified,with the purity >80%,by ammonium sulfate pre-cipitation and CL-4B gel filtration;analysis of the purified fusion protein ,using size exclusion chromatography with multi-angle laser light scattering detection ( SEC-MALS) and electron microscope ,revealed that HBc-L2 was assembled into a stable VLP structure auto-matically following its expression;immunization of BALB/c mice with the purified VLPs resulted in high antibody titers in mouse sera against the L2 epitopes;furthermore,it was demonstrated that the sera from the immunized mice had neutralization activities against both HPV16 and HPV18.Conclusion:The immunogenicity of the L2 epitopes was highly enhanced by the construction of HBc-L2 fusion protein and the formation of the VLP structure;the fusion protein was also capable of inducing protections against different serotypes of HPV,therefore,it could be a potential HPV vaccine with a broad coverage and low production cost .

BACKGROUND: Artificial humeral head replacement is an effective method for the treatment of complex proximal humeral fractures, which has received good results in relieving pain. However, the final functional recovery is unpredictable. OBJECTIVE: To compare biomeshanical stability between anatomical and overlapping reconstruction of the greater tuberosity in cadaveric humeral head replacement models.METHODS: Eight pairs of fresh-frozen shoulder cadavers (16 shoulder joints) were match-paired into two groups. Standardized humeral head replacement procedure was performed in all specimens, and anatomical and overlapping reconstruction of thegreater tuberosity was adopted in each group respectively. For overlapping group, the greater tuberosity was reattached to the proximal humeral shaft in an overlapping style, which was achieved by an additional 5 mm bone osteotomized from the medial cortex of the humeral diaphysis. Custom mounting apparatus and fixation jigs were designed for designated shoulder motion.RESULTS AND CONCLUSION: When the shoulder was external rotated to neutral position, the mean displacement of greater tuberosity in the anatomical reconstruction group was smaller than that of the overlapping reconstruction group (P < 0.05). When the gleno-humeral joint was elevated to 30～ and 60～ forward flexion (accounting for 45° and 90° shoulder forward flexion), there was no significant difference of greater tuberosity displacement between the anatomical group and overlapping group. The findings demonstrated that, although overlapping reconstruction can increase the bone healing area between the greater tuberosity and the humeral diaphysis, there may be some loss in mechanical stability as the trade-off. Even though we strictly follow the standardized postoperative rehabilitation protocol after humeral head replacement, prominent displacement between the greater tuberosity relative to the humeral diaphysis was detected. Accordingly, postponing of the postoperative rehabilitation program after humeral head replacement for a decent period may improve tuberosity healing.

This study aimed at investigating the dose-effect relationship of SFI between the blood viscosity and the early-and mid-stage cardiogenic shock and the mediatory effect on rats.The end or root of left anterior descending coronary arteries (LADCA) was ligatured to establish the rat model of the early-and mid-stage cardiogenic shock.The blood viscosity indexes included low shear rate (LSR,10/s),middle shear rate (MSR,60/s),high shear rate (HSR,150/s) of the whole blood viscosity and plasma viscosity (PV),being observed 60 mins after the venous administration of 0.10,0.33,1.00,3.30,10.00 and 20.00 mL·kg-1 SFI (low dosage range:0.1-1.0 mL·kg-1,middle dosage range:1.0-10 mL·kg-1,high dosage range:10-20 mL·kg-1) with a blood rheometer.Dose-response curves were fitted by GraphPad Prism 6.0 software,the dose-response relationship of SFI between the blood viscosity and the early-and mid-stage cardiogenic shock in rats was evaluated to calculate the dose threshold parameters of the indexes.It was found that the blood viscosity indexes were improved with the dosage of 10 mL·kg-1 SFI in rats with the early-stage cardiogenic shock,while the dose-response curves of LSR,MSR and HSR at the early stage all presented favorable s shapes.Most of the effective dose range [D]2o-[D]80 and the threshold dose [D]20 were between 3.3 and 6.3 mL· kg-1.The four indexes of blood viscosity were improved with the administration of 10 and 20 mL·kg-1 SFI in mid-stage model rats with favorable s shapes in the dose-response curves.Most of the effective dose range and the threshold dose were in the range of 3.3 to 10.0 mL·kg-1.In conclusion,most of the dose-response curves of blood viscosity indexes in early-and mid-stage cardiogenic shock rats presented favorable s shapes with the threshold dose between 3.3 and 10.0 mL·kg-1,indicating an effective middle dosage range,which was converted into clinical dosage about 37.1 to 112 mL each day.The research provided an experimental basis for clinical medication.
