Acute myocardial infarction (AMI) is caused by acute occlusion of the coronary artery. The partial necrosis of the myocardium is caused by severe and prolonged ischemia,which is characterized by persistent and severe chest pain, the high mortality rate. Fast recovery can be achieved the coronary artery blood circulation by emergency percutaneous coronary intervention (PCI), can improve myocardial is-chemia, save moribund myocardium. The medical profession is generally believed that on the basis of en-suring the safety of patients with AMI, the normal rehabilitation should be carried out as soon as possible. In this article, the domestic in recent years, AMI emergency PCI in early postoperative rehabilitation treatment method, the intensity and evaluation index of three aspects were summarized. The starting time of the early rehabilitation of AMI patients in foreign countries is earlier than our country. As we all know that via radial artery PCI has the smaller puncture and more convenient hemostasis, so there is no doubt that it can pro-vide favorable conditions for recovery of patients. Therefore, it is necessary to expand the research field in order to determine the best rehabilitation opportunity and the most excellent rehabilitation program , so as so determine the best recovery time and the most excellent rehabilitation program in patients with AMI after PCI operation.

Objective To investigate the effects of Shuxuetong on hemodynamics and serum sICAM-1,IL-6,TNF-α in patients with cerebral infarction.Methods A hundred patients with cerebral infarction were randomly divided into observation group and control group from Jan 2011 to Jan 2015.Fifty patients in control group were treated with conventional therapy alone and 50 patients in observation group were treated with conventional therapy combined with intravenous injection with Shuxuetong.The changes of hemodynamics were observed before and after treatment and the levels of serum sICAM-1,IL-6,TNF-α were detected by enzyme linked immunosorbent assay (ELISA).Results No statistical significance was found in hemodynamics of control group before and after treatment (P ＞0.05).The indexes of hemodynamics in observation group were significantly improved compared with those in observation group before treatment and those in control group after treatment (P＜ 0.05).The levels of serum sICAM-1,IL-6,TNF-α were significantly reduced in two groups after treatment (P ＜0.01) and the levels of serum sICAM-1,IL-6,TNF-α after treatment were significantly lower in observation group than those in control group (P＜0.01).Conclusion Shuxuetong can effectively improve the indexes ofhemodynamics and reduce the levels of serum sICAM-1,IL-6 and TNF-α.It has a positive effect on the treatment of cerevral infarction.

Objective To investigate the effect of Rho GDP dissociation inhibitor 2 (RhoGDI2) and Bcl-2 in pathogenesis of hypoxic-ischemic brain damage (HIBD).Methods Neonatal 7-day-old Sprague Dawley rats were randomly divided into sham-operation control group,HIBD 6 h group and HIBD 48 h group (n =10 per group).The apoptosis rate of brain cell was measured by flow cytometer and the expression of RhoGDI2 mRNA and Bcl-2 mRNA were detected by Real-time RT-PCR.Results ( 1 ) The ligated cerebral hemisphere of neonatal rats showed obvious edema at 48 h after hypoxia-ischemia.( 2 ) Apoptotic cell appeared at 6 h in HIBD group,the apoptosis rate was ( 1.40 ± 0.12 ) ％.The apoptosis rate obviously increased to (15.86 ±0.98)％ at 48 h after HIBD,which showed a significant increase compared to sham-operation control group ( P ＜ 0.01 ).( 3 ) The expressions of both RhoGDI2 mRNA and Bcl-2 mRNA were 4.12 ±0.74 and 2.55 ± 0.65 respectively in sham-operation control group.In HIBD group,the expressions of both RhoGDI2 mRNA and Bcl-2 mRNA began to decrease at 6 h after HIBD ( 3.19 ± 0.77,1.96 ± 0.36) and decreased furthermore at 48 h after HIBD ( 1.04 ±0.18,1.06 ±0.17 ).The differences of expression levels among three groups were statistically significant (P ＜0.01 ).(4) The expression of RhoGDI2 mRNA positively correlated with the expression of Bcl-2 mRNA ( r =0.831,P ＜ 0.05 ).Conclusion With the emerging of apoptosis after HIBD,the expressions of both RhoGDI2 mRNA and Bcl-2 mRNA are decreased.The imbalance of expression of RhoGDI2 is involved in pathogenesis of HIBD by regulating Bcl-2 expression.

Objective To estimate the operative risk and outcomes of colorectal cancer patients 80 years of age and older. Methods Colorectal cancer resection was performed in 99 patients 80 years of age and older between Dec. 1987 and June 2005. The informations about clinical data, co-morbidity,complications, operative mortality and survival were retrospectively analyzed. The patients were followed-up for 45.12 months (range 1-136) months. Results Of 99 patients, co-morbidity was found in 43 patients (43.4% ) and complication in 10 patients (10.1%). No patient died of operation.Eighty patients completed the follow-up study. The overall 3-year survival rate and disease-free survival rate were 64.3% and 61.1%, respectively. Whereas the overall 5-year survival rate and disease-free survival rate were 52.8% and 52.1%, respectively. In univariate analysis, curative or palliative operation, tumor differentiation, cancer embolism in the vasculature, tumor staging and complications were proved to be significant prognostic factors. Multivariate survival analysis,however, showed that only the curative or palliative operation was independent factor for survival.Conclusions The high risk of co-morbidity for patients 80 years of age and older is not the obstacle to cancer resection.These patients will have satisfactory outcomes via optimal treatment and operation.

Objective To explore the effects of low density lipoprotein(LDL) containing immune complexes(IC) on the mRNA expression of matrix metalloproteinase-1(MMP-1) and matrix metalloproteinase-1(TIMP-1) in U937 cells.Methods U937 cells were incubated with native LDL,oxidized LDL or LDL-IC,respectively.mRNA expression of matrix metalloproteinase-1(MMP-1) and tissue inhibitor of metalloproteinase-1(TIMP-1) in U937 cells were measured by reverse transcriptase polymerase chain reaction(PT-PCR).Results Normal U937 cells hardly expressed MMP-1,but highly expressed TIMP-1.N-LDL had no effect on the expression of MMP-1 and TIMP-1 mRNA.Ox-LDL can induce slightly expression of MMP-1 and markedly down-regulate expression of TIMP-1.Similarly,nature and oxidized LDL-IC had significantly more effect on the mRNA expressions of MMP-1 and TIMP-1 than that of control(P

Objective To discuss the value of glucocorticoid steroids (GCs) in the treatment of patients with severe community-acquired pneumonia (SCAP) complicated with septic shock.Methods A prospectively controlled randomized trial was conducted.Fifty-eight SCAP patients complicated with septic shock admitted to emergency intensive care unit (ICU) of China-Japan Friendship Hospital from May 2014 to February 2016 were enrolled.The patients were randomly divided into conventional treatment group (n =29) and GCs group (n =29).Fluid resuscitation,vasopressors,mechanical ventilation if needed,antibiotics and other general treatment including symptomatic treatment and eliminating phlegm were given to patients in both groups.Beside the treatment mentioned above,80 mg methylprednisolone once a day for 7 days was added to patients in GCs group.The changes in oxygenation index (PaO2/FiO2) and C-reactive protein (CRP) at 1,4,8 days after treatment as well as the imaging improvement in both groups were observed.Discharge or death was set as a cut-off point,the average time of temperature controlling,duration of mechanical ventilation,time of vasopressors usage and 28-day mortality were observed.The incidence of hyperglycemia,infection and hemorrhage of digestive tract were observed.Results There were no statistically differences in gender,age and body mass between the two groups,indicating that baseline data for the two groups were balanced.PaO2/FiO2 after treatment in the two groups was gradually increased,and it was significantly higher at 8 days after treatment in GCs group than that of conventional treatment group [mmHg (1 mmHg =0.133 kPa):426.46 ± 86.97 vs.363.00 ± 83.96,P ＜ 0.05].CRP after treatment in the two groups was gradually decreased,and it was significantly lower at 4 days and 8 days after treatment in GCs group than that of conventional treatment group (mg/L:95.78 ± 47.38 vs.124.72 ± 51.01,57.60 ± 47.44 vs.88.85 ± 48.18,both P ＜ 0.05).Radiographic imaging improved rate at 4 days and 8 days after treatment in GCs group was significantly higher than that of conventional treatment group (55.2％ vs.27.6％,75.9％ vs.51.7％,both P ＜ 0.05),and average time of temperature controlling (days:3.94 ± 2.39 vs.7.22 ± 3.11),time of vasopressors usage (hours:13.64 ± 6.47 vs.28.34 ± 12.56),and the average hospitalization days (days:28.50 ± 8.61 vs.36.21 ± 15.26)in GCs group were significantly shorter than those of conventional treatment group (all P ＜ 0.01).There was no significant difference in duration of mechanical ventilation between GCs group and conventional treatment group (days:13.39 ± 2.62 vs.16.16 ± 5.85,P ＞ 0.05).28-day mortality of the two groups was 10.3％ equally (P ＞ 0.05).No significant differences in the incidences of hyperglycemia (10.3％ vs.6.9％),infection (51.7％ vs.55.2％) and gastrointestinal bleeding (3.4％ vs.0) were found between GCs group and conventional treatment group (all P ＞ 0.05),indicating that glucocorticoid steroids could not increase the common side effects.Conclusion GCs is an important adjuvant treatment of patients with SCAP complicated with septic shock.

Objective To observe the effects of human retinal pigment epithelium conditioned medium(HRPE-CM) on the biological characteristics of human retinal stem cells(HRSCs). Methods HRSCs were exposed to HRPE-CM and cultivated in three different cultures,including the control,epidermal growth factor(EGF) + basic fibroblast growth factor(bFGF) and HRPE-CM.Cell counting was performed to explore the effects of different culture media on the proliferation of HRSCs,and their properties as neural stem cells were further identified. Results Compared with control group,HRPE-CM significantly promoted the proliferation of HRSCs(P

Background The ultrastructure change and growth of corneal nerve after laser in situ keratomileusis (LASIK) are some influent factors to the stability of tear film and the sensibility of cornea.Some relevant studies are lack up to now.Objective This study is to observe the changes of ultrastructure of corneal epithelium and regeneration of corneal nerve fiber.Methods LASIK was performed on the lateral eyes of 48 New Zealand white rabbits.Rabbit eyes were excavated at instant in postoperation,one day,seven days,one,three and six months after LASIK.Change of corneal ultrastructure and corneal nerve staining were examined under the scanning electron microscope (SEM) and transmmision electron microscope (TEM) at the time points mentioned above.The numbers of microvilli of corneal epithelial cells in different postoperative time were analyzed.10% AuCl was used to evaluate the growth status of corneal nerve in different time after LASIK.Results Irregularity of microvillus of corneal epithelial cells,degrease of cell density were seen under the TEM and some cavities could been observed in the instant of postoperation.The connection abnormality of intercells,dropsy and rupture of microvillus were presented under the SEM,However,the ultrastructure of corneal epithelial cells was almost normal in 7 days after LASIK.The numbers of microvillus in corneal epithelial cells were significantly declined in the postoperative instant group compared with preoperative group (P＜0.05),but no evidently difference was found in postoperative 1 day and 7 days groups compared with preoperative group(P＞0.05).Corneal nerve staining showed that in 1 day after surgery,nerve plexus was deprivation and boundary of nerve injury was clear and nerve fibers were cut off.After one month some reborn nerve fiber grew into the cornea flap.Reborn corneal nerve fiber can be seen at center laser ablation area after six months of LASIK.Conclusion The ultrastructure change of corneal epithelial cells in the early stage after operation may be a important factor causing dry eye symptom following LASIK.The growth fashion of corneal nerve fibers is from the cutting edge to the center of corneal flap.

Objective To explore the effect of the thyroid morphologic change,the initiating treatment time and the thyroid function(serum FT_4,TSH)on mental development in children with congenital hypothyroidism (CH).Methods After diagnosed,52 cases of CH were orally administrated with L-T_4,then their mental and physical development were monitored and thyroid morphologic changes were observed by thyroid imaging(~(99m)TcO_4) and type B ultrasonography.The Bayley test was performed at the age of 10 to 30 months and expressed as mental developmental index(MDI)and psychomotor developmental index(PDI).Analysis was conducted upon treatment timing and thyroid morphologic changes.Results The MDI in those cases with morphologic abnormalities treated within 90 days was significantly lower than that with normal morphology(91?20 vs 105?15,P

AIM To establish the model of exudative pleurisy induced by alternatively activating complement and to study protection of anti inflammatory drugs on it. METHODS Purified cobra venom factor (CVF) was injected into the pleura, and then exudate volumn, total leukocyte count, protein content and histamine concentration were determined. RESULTS CVF, injected into rat pleura at dose of 0 08～2 mg?kg -1 , induced exudative inflammation in dose dependent and time dependent manner. Both diphehydramine and isoprenaline reduced significantly exudate volume, total leukocyte count, protein content and histamine concentration, while indomethacin, dexamethasone and cyclophosphamide also reduced exudate volume, total leukocyte count and protein content, although they did change the release of histamine. DLF, one of the toxic components in cobra venom, potentiated CVF induced inflammation. CONCLUSION CVF can induce significantly exudative pleurisy sensitive to anti inflammatory agents. DLF has augmentation on CVF induced inflammation.
