Objective To study disfunction of activated T cell from peripheral blood and explore its role on pathogenesis in patients with refractory mycoplasma pneumoniae pneumonia (MPP).Methods T cell subsets and expression of membrane molecule on activated T cell in peripheral blood were measured in 26 refractory MPP patients by using immunofluorescence and flowcytometry,and compared with those of 18 control healthy children.Results The percentage of CD4~+ cell from peripheral blood in refractory MPP children was significantly lower than that in control group(P0.05).Conclusions There are disfunctions of T cell in refractory MPP patients in acute period,and the abnormal T cell activated disfunction may play an important role on pathogenesis.

Summary: Receptor mediated gene delivery is a new gene transfer strategy. Asialoglycoprotein receptor (ASGP-R), the receptor of asialoorosomucoid (Asor), is specially expressed on the surface of hepatocyte. In this paper, the nuclide 131I was combined with Asor to form a kind of soluble nuclide-protein complex, which can be specifically endocytosed into hepatocyte by ASGP-R. After intravenous injection of the complex into experimental animals, the deposition of Asor in vivo and the targeting quality of hepatocyte was detected by ECT. This research testified the feasibility of targeting Asor complex delivery to hepatocyte mediated by ASGP-R in vivo, and provided foundation for the genetic diagnosis and gene therapy of hepatic cell-related diseases.

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.

Aim To observe whether the activation of aldehyde dehydrogenase 2 ( ALDH2 ) can protect a-gainst diabetes induced liver injury in rat model, and analyze the role of JNK pathway in the liver protection induced by activation of ALDH2 . Methods All male SD rats were randomly divided into three groups: nor-mal control group ( Con ) , diabetes group ( DM ) and ethanol + diabetes group ( EtOH + DM ) . After 8 weeks, the fasting blood glucose ( FBG) level, glyco-sylated hemoglobin ( HbA1c) level, serum AST and ALT levels were measured. The changes of hepatic pa-thology were observed by hematoxylin and eosin ( HE) staining method. The protein expressions of ALDH2, JNK and p-JNK in liver tissue were measured. Result Compared with control group, in DM group, the lev-els of FBG and HbA1c, serum AST and ALT levels were increased significantly. The structure of liver mor-phology was destroyed, disarranged and unclear, the hepatocyte was swollen, and a large number of inflam-matory cells were infiltrated. ALDH2 protein expres-sion was decreased, while the expressions of JNK, p-JNK and the ratio of p-JNK/JNK were increased. Com-pared with DM group, in EtOH+DM group, the levels of FBG and HbA1c, serum AST and ALT levels were decreased. The expression of ALDH2 protein was in-creased, accompanying with the decrease of JNK, p-JNK protein expressions and the ratio of p-JNK/JNK. Conclusion Activation of ALDH2 can protect the liv-er against diabetes induced liver damage in rat model, which may be relevant with inhibiting the JNK path-way.

BACKGROUND: Deep vein thrombosis (DVT) of the lower limbs is one of the severe complications of total hip replacement (THR)during the perioperative period. The incidence rate was high. The effect of primary disease on the DVT after THR in the elderly remains poorly understood.OBJECTIVE: To explore the effect of primary disease on DVT after THR in the elderly.METHODS: 147 cases with unilateral THR aged 64-93 years, were included and divided into two groups. Fracture group contained 68 cases, which of them were all traumatic femoral neck fracture ones. Osteopathia group contained 79 cases, and they had no traumatic injury. We selected total hip prostheses according to their physiological age, preoperative socialization ability,substantia ossea and life expectancy. Biological prosthesis in 5 cases and mixed prosthesis in 12 cases were used, while the others used bone cement prosthesis. If the patient had pain and/or swelling on the injured limb, with or without Homans/Neuhofs sign, we did the pressurized ultrasonic Doppler to examine whether the patient had got DVT.RESULTS AND CONCLUSION: In the fracture group, 32 cases had swelling in the injured limbs, and 20 cases with pain, 15 cases with Homans/Neuhofs sign, and 29 DVT cases were confirmed by the pressurized ultrasonic Doppler. One femoral neck fracture case of THR had no DVT clinical signs and was dead 17 days later. The autopsy found that it was an mixed type combined of pulmonary embolism; Osteopathia group: 20 cases had swelling in the injured limbs, and 11 cases of pain, 9 cases of Homans/Neuhofs sign, 20 DVT cases were confirmed by the pressurized ultrasonic Doppler. The blood coagulation state was greater, and the incidence rate of DVT in the lower limbs was greater in the fracture group compared with osteopathia group (P ＜ 0.05). These indicated that femoral neck fracture is a high risk factor for DVT development in lower limb affer THR in the elderly.

ObjectiveTo investigate the prevalence of nutritional risk and perioperative nutritional support status in the gastrointestinal cancer surgical patients.Methods Adult inpatients from the gastrointestinal cancer surgery department of our hospital were consecutively enrolled from May to September 2010.Nutritional Risk Screening 2002 ( NRS 2002) was performed at admission,and data of the nutritional support and complications during hospitalization were collected.The relationship between nutritional risk and postoperative complications was analyzed.ResultsA total of 195 patients were eligible.At admission,43.6％ (85/195) patients were at riskOf the patients at risk,totally 11.7％ (10/85) patients received preoperative nutritional support,and 100％ (85/85) patients received postoperative nutritional support; of the patients not at risk,no patients received preoperative nutritional support,and 84.5％ (93/110) patients received postoperative nutritional support.The overall rates of postoperative complications were 19.1％ ( 13/68 ) in the patients at risk while 7.1％ (9/127 )in the patients not at risk ( P =0.02).ConclusionsNutritional risk in gastrointestinal cancer surgical patients was high.The application of nutritional support was inappropriate in these patients.The nutritional risk is associated with higher postoperative complications.Dissemination of evidence-based guidelines should be enhanced.
