Objective To evaluate the effect of the individualized health management on senile mental disorders.Methods 421 patients with senile mental disorders were randomized into two groups:the intervention group (n =213) received routine antipsychotic drugs treatment,health education and individual health management,and the control group(n=208) received only population health education and routine drug antipsychiatric treatment.Results The Brief Psychiatric Rating Scale (BPRS) scores in two group were significantly higher after treatment than before treatment (all P＜0.01).The BPRS score in each period after treatment were significantly higher in intervention group than in control group (all P＜0.01).The mini mental state examination (MMSE) score in two treatment groups were significantly higher after treatment than before treatment (all P＜0.01).The MMSE score in each period after treatment were significantly higher in intervention group than in control group (all P＜0.05).Conclusions The individualized health management in senile mental disorders is not only feasible,but also effective.

In order to investigate the ipsilateral lymphadenectomy for inhibiting rejection in rat corneal transplantation, corneal allogenic transplantation models were established in rats. Eighteen female Wister rats were used as donors, and 36 Sprague Dawley rats as recipients. After penetrating corneal transplantation, recipients were randomly divided into 3 groups: group A (control group); group B, the ipsilateral lymphadenectomy group; group C, the bilateral lymphadenectomy group. Among 12 rats in each group, the corneas of 2 rats in each group were used for pathological study at day 14 after the transplantation, and the remaining 10 rats were used for studying corneal rejection by a slit lamp. The time points when allograft rejection occurred were recorded and mean survival time (MST) was compared. The results showed that MST in groups B and C was 46.30 +/- 9. 464 days and 44.43 +/- 7. 604 days, respectively, which was significantly prolonged as compared with that in group A (10.71 +/- 1.567 days, P < 0.01). There was no significant difference in MST between groups B and C (P > 0.05). It was concluded that both bilateral and ipsilateral lymphadenectomy therapies could effectively inhibit the corneal allograft rejection. Ipsilateral lymphadenectomy is a less complex surgical procedure and is just as effective in preventing rejection.

To study corneal lymphangiogenesis after corneal transplantation, corneal allogenic transplantation models were established in rats. 8 female Wister rats were used as donors, and 16 Sprague Dawley (SD) rats were used as recipients and 2 SD served as controls. Corneal lymphangiogenesis and hemangiogenesis was examined by electron microscopy 1 and 2 weeks after corneal penetrating transplantation, and the expression of lymphatic vessel endothelial receptor (LYVE-1) was examined 1, 3, 7, 14 days after the transplantation respectively. In addition, 19 allograft failed human corneas were examined by 5'-nase-alkaline phosphatase (5'-NA-ALP) double-enzyme-histochemistry staining to detect corneal lymphangiogenesis and hemangiogenesis. By immunohistochemistry for LYVE-1, it was found that blown lymphatics were localized in the stroma 3 days after the corneal transplantation. With electron microscopy, new lymphatic vessels and blood vessels were found 1 and 2 weeks after the corneal transplantation. By 5'-NA-ALP enzyme-histochemistry, corneal hemangiogenesis was found in all allograft failed human corneas and 5 of 19 (26.3 %) cases had developed corneal lymphangiogenesis. It is concluded that corneal lymphangiogenesis is present after corneal transplantation, which may play an important role in allograft rejection.

This paper is to report the study of the microscopic and macroscopic he-morrheological changes and the conditions of the nail-fold microcirculation in 30 patients with severe viral hepatitis. Normal 'individuals, patients with acute icteric hepatitis, and those with chronic active hepatitis were employed as the controls.The changes observed in the patients with severe viral hepatitis were as follows: The reduced viscosity of the whole blood and the plasma viscosity increased markedly, the dispersion rate of the blood viscosity values increased as the clinical state of the patient became more severe, and the factors increasing the blood viscosity (namely, increase of the amount of immune globulin, pro-longation of the electrophoretic time of RBC, increase of RBC sedimentation rate), and the factors decreasing the blood viscosity (namely, decreases of he-matocrit reading, fibrinogen, and the aggregation ratio of platelets) existed simultaneously. The changes of the flow condition and velocity of the nail-fold microcirculation were in close correlation with the increase of blood viscosity and the severity of the disease.The causes and the mechanism of the above-mentioned changes were discussed.

Objective To investigate the pathogenesis,diagnosis,treatment and prognosis of aort-oesophageal fistula(AEF).Methods Retropective analysis was performed on 6 patients presenting with AEF between January 2002 and December 2014,and relative literature was reviewed on its pathogenesis,di-agnosis,prognosis and treatment.Results Five men and 1 woman with a mean age of 49 (range,27-71 years)were recruited to the study.One case of AEF was caused by esophageal foreign body,2 cases were caused by aneurysm while the other 3 patients presented AEF after aortic surgery.All 6 patients showed he-matemesis,among whom 3 presented sentinel hemorrhage,1 presented exsanguination after sentinel hemor-rhage,2 presented sudden exsanguination.Among 4 patients with sentinel hemorrhage,2 accompanied with chest pain,1 with dysphagia and 1 with fever.Two patients had a history of hypertension.Diagnostic rate was nearly 100% by gastroscopy or CT/CTA.Four patients died from hemorrhagic shock and 2 patients re-covered from surgery.Conclusion AEF should be seriously considered for patients with a history of hyper-tension,aortic disease or esophageal foreign body presenting sentinel hemorrhage,chest pain,dysphagia,fa-tal exsanguination followed by symptom-free interval.Prompt examinations and aggressive surgery are of great significance for survival.

AIM:To investigate the effects of atorvastatin reloading in pre-percutaneous coronary intervention ( PCI) period on endothelial progenitor cell ( EPC) count and inflammatory cytokine expression in the stable angina pectoris patients who had previously received long-term statin treatment.METHODS:The patients with stable angina pectoris that had received long-term statin therapy and planned to accept PCI were randomized into 3 groups:80 mg atorvastatin 12 h and 40 mg 2 h before coronary angioplasty (80 mg reloading), pre-operatively with 40 mg/d atorvastatin for 7 d (40 mg re-loading) , and without atorvastatin reloading ( no reloading ) .CD45 -/CD133+/CD34 +, CD45 -/CD34 +/KDR+ and CD45 -/CD144 +/KDR+EPCs in 100 μL peripheral blood were determined by flow cytometry 1 h prior to PCI and 1 h, 6 h and 24 h after PCI.The serum concentrations of soluble intercellular adhesion molecule 1 ( sICAM-1) , C-reactive protein ( CRP) and troponin I ( TnI) were analyzed immediately prior to and 24 h after PCI.RESULTS:(1) In 80 mg reloading group, the numbers of circulating CD45 -/CD133 +/CD34 +and CD45 -/CD34 +/KDR+early differentiation stage EPCs 1 h and 6 h after coronary angioplasty was significantly elevated compared with those before PCI (P<0.05).(2) In control group, the serum concentrations of sICAM-1 and CRP 24 h after PCI were significantly elevated ( P<0.05) compared with preoperative values.(3) The rise in serum TnI concentration from pre-to post-operation in 80 mg reloading group was lowerthan that in control group.CONCLUSION: The method of atorvastatin reload before PCI affects the number of EPCs inperi-operative period.High dose of atorvastatin application before PCI triggers early EPC circulation.The serum levels ofpost-operative inflammatory cytokine sICAM-1 as well as CRP are reduced by atorvastatin reloading before PCI.

The difficulty of neural localization during operation often leads to the increased risk of nerve injury, which results in neurological dysfunction, so how to accurately locate the nerves in surgeries, such as operations for patients with recurrent parotid tumors and prostate surgery, has become one of the key factors for the success of the operation. There are many methods to locate nerves in real time during operation, among which fluorescence imaging has attracted more and more attention due to its unique advantages of high sensitivity, easy to use, low cost and no radiation. In this article, the related research progresses of fluorescence imaging in neural localization are reviewed.

The expression of VEGF-C and molecular mechanisms of lymphangiogenesis in rat cornea after alkali injury was studied. The rat alkali injured corneal models were made. Under electron microscopy, the lymphatic vessels in the rat injured corneas were examined. The expression of VEGF-C proteins was detected by using immunohistochemical assay at day 1, 3, 5, 7, 9 after injury. The expression levels of VEGF-C mRNA were quantified with reverse transcription polymerase chain reaction (RT-PCR). The results showed that the lymphatic vessels were found in the injured rat corneas 14 days after the injury. The VEGF-C protein was detectable 3 days after injury, reached the peak 5 days after injury, and gradually decreased. In the control group, no VEGF-C proteins were detected. The VEGF-C mRNA was minimally detected in the normal rat corneas, but it was highly expressed 5 days after the injury. The difference was statistically significant. It was concluded that VEGF-C might be one of the most important relevant factors in corneal lymphangiogenesis after alkali injury.
