International Eye Science 2016;16(10):1902-1904
AIM: To investigate the clinical effect of compound anisodine on patients with paralytic strabismus and the influence on malondialdehyde ( MDA ) and superoxide dismutase ( SOD) .
●METHODS: Seventy cases diagnosed with paralytic strabismus from Jun. 2008 to Dec. 2014 were selected as treatment group; another 70 cases with paralytic strabismus from Oct. 2000 to Jan. 2008 were chosen as control group. The control group was given with conventional therapy, and treatment group was additionally injected with compound anisodine subcutaneously on the basis of the control group. Treatment lasted for two courses about 28days. The effect of compound anisodine on patients with paralytic strabismus was evaluated and the serum level of MDA and SOD was also measured before and after treatment.
●RESULTS: ln treatment group, 54 cases were cured (77%), 14 cases improved (20%) and 2 cases had no response ( 3%) and total efficiency reached to 97%. ln control group, 32 cases were cured ( 46%) , 21 cases improved ( 30%) and 17 cases had no response ( 24%) and total efficiency was 76%. The cure rate and total efficiency of treatment group were significantly higher than that of control group (P<0. 05). Before treatment, the level of SOD and MDA was equal in two groups. After treatment, increased SOD level and decreased MDA level was observed in both groups. However, compound anisodine were significantly increased SOD level and reduced MDA level when compared with conventional therapy (P<0. 05).
●CONCLUSION: The compound anisodine shows the beneficial effect on patients with paralytic strabismus. Compound anisodine may exert the effect via increasing SOD and reducing MDA.

Chinese Journal of General Surgery 2013;28(9):705-708
Objective To investigate the effect of early embryonic mouse pancreatic tissue transplantation in the treatment of mouse experimental diabetes.Methods C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups:transplantation group,in which,five to seven pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule,and sham-operated (SO) control group,in which,0.05 ml RPMI1640 culture medium was injected into mouse renal capsule.When blood glucose level of the transplantation group mouse was ≤ 11.2 mmol/L,the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose surge.In vitro,levels of insulin secretion were measured in serum,E16.5 pancreatic tissue and graft (3.3 mmol/L and 16.7 mmol/L) glucose stimulation by ELISA.Histology and immunohistochemistry were observed before or after pancreatic tissue transplantation to detect insulin and glycagon production.Results (1) The glucose level decreased significantly in the TX group after 4-6 weeks of transplantation (13.4 ± 6.5 vs 28.9 ± 2.5,P < 0.05),and the body weight gaining (P < 0.05).Compared to SO group,glucose level decreased significantly (P < 0.001).The graft can modulate insulin secretion; (2) Insulin can be detected in E16.5 embryonic mouse.Insulin and glycagon were produced more in TX group than pretransplantated pancreatic tissue.Conclusions E16.5 embryonic mouse pancreatic tissue transplantation effectively controls serum glucose level and restore the nondiabetic pattern of weight gaining in diabetic mouse.
7.Advance of clinicopathological and molecular research of triple negative breast cancer
China Oncology 2013;(8):603-608
Triple negative breast cancer (TNBC) is characterized by the lack of expression of hormone receptors, as well as human epidermal growth factor receptor 2 and displays special biological and clinicopathological characteristics. This subtype is aggressive in nature with high histological grade. Besides invasive ductal carcinoma,several special histological types have also been found. The features of the TNBC subgroup roughly parallel those of the basal-like subgroup. Due to the lack of molecular targets, this subgroup has no chance of endocrine treatment and target therapy. Currently, the treatment of TNBC is dominated by chemotherapy based on anthracycline with suboptimal efficacy. Overall, the prognosis has remained quite poor. Emerging evidence indicates that patients regimens with triple negative breast cancer usually displays high rate of early recurrence and distant metastasis. Both the diseasefree survival and overall survival rates are low. Although this subtype which shows same immunohistologic pattern, great heterogeneity still exists within the group causing distinctions in morphology, prognosis, and more importantly, drastically different reactions to same treatment protocol. In recent years, TNBC has been widely concerned by both clinician and pathologist. Several targeted drugs for corresponding signal pathway as well as the subtype of triple negative breast cancer have been widely studied. This article focused on the advances in clinicopathological characteristics, new subtypes and treatment of triple negative breast cancer.
8.Research on aberrant expression of HOX in gastrointestinal neoplasms and its mechanism
International Journal of Surgery 2012;39(6):396-399
Homebox genes are known to determine cell proliferation and differentiation and subsequently regulate the occurrence,development and prognosis of many tyhpes of malignant tumors in human.Some recent studies have shown that homebox genes are abnormally expressed in the esophageal,gastric,coloreetal and other gastrointestinal tumors.In this review,we consider that homebox genes may regulate the occurrence,development of gastrointestinal tumors by interacting with transcription factors in vivo and abnormal epigenetic modifications.Therefore,homebox genes are closely related to gastrointestinal tumors.

Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2014;(1):50-54
Objective To observe the effect of penehyclidine hydrochloride (PHCD) combined with mechanical ventilation on inflammatory response in rats with acute respiratory distress syndrome(ARDS)induced by hydrochloric acid(HCl)inhalation. Methods 32 adult healthy male Sprague-Dawley(SD)rats were randomly divided into four groups:sham operation group,ARDS model group,PHCD group(intraperitoneal injection of 0.5 mg/kg PHCD at 30 minutes before HCl instillation)and mechanical ventilation group〔mechanical ventilation was given after PHCD treatment,ventilator settings were as follows:tidal volume(VT)=4 mL/kg,respiratory rate(RR)= 70 beats/min,the time ratio of inspiration to expiration(I:E)=1:2,fraction of inspired oxygen concentration(FiO2)=0.21〕,8 rats in each group. The rat ARDS model was created by HCl(0.1 mol/L,1.2 mL/kg) intratracheal instillation. After mechanical ventilation for 4 hours,the experiment was stopped. Arterial partial pressure of oxygen(PaO2)was measured,and the oxygenation index as well as lung wet/dry weight ratio(W/D)were calculated respectively. The pathological changes in lung tissues were observed under light microscope,and the pathological score was evaluated. The levels of myeloperoxidase(MPO),interlukin-8(IL-8)and nuclear factor-κB (NF-κB)in homogenate of lung tissues were all measured respectively by enzyme linked immunosorbent assay (ELISA). Results In rats of ARDS model group, there were significant infiltration of inflammatory cells, collapse of extensive pulmonary alveoli and hyaline membrane formation in lung tissues,but the edema in pulmonary mesenchymal tissue and congestion of micro vessels were not obvious. Compared with sham operation group,the lung tissue pathological score(9.88±2.03 vs. 1.38±0.92),lung W/D ratio(7.67±0.96 vs. 4.08±0.65)were significantly increased(both P<0.01),while oxygenation index〔mmHg(1 mmHg=0.133 kPa):213±29 vs. 428±28〕was markedly decreased in model group(P<0.01);and the concentrations of MPO(μg/L:34.18±3.99 vs. 20.92±1.40), IL-8(ng/L:864±53 vs. 583±91)and NF-κB(ng/L:1 229±133 vs. 803±130)in homogenate of lung tissues were significantly higher in model group(all P<0.01). The pathological changes in lung tissues including inflammatory cell infiltration,collapse of alveoli and pulmonary edema,etc. were obviously improved when treated by PHCD or mechanical ventilation and the lung pathological score and W/D ratio were significantly decreased compared with those of model group,oxygenation index in these two groups were both significantly increased,meanwhile, the concentrations of MPO,IL-8 and NF-κB were sharply decreased when compared with those of model group (all P<0.05). The degree of improvement in all above indexes were greater in mechanical ventilation group than those in PHCD group(lung injury score:5.63±1.85 vs. 7.63±1.67,lung W/D ratio:5.35±1.05 vs. 6.46±1.17, oxygenation index:325±57 vs. 272±44,MPO:25.80±3.36 vs. 29.88±3.93,IL-8:736±53 vs. 802±53, NF-κB:984±75 vs. 1 109±118,all P<0.05),however they did not reach the levels of the sham operation group (P<0.05 or P<0.01). Conclusion PHCD can inhibit the inflammatory response in ARDS rats induced by HCl inhalation,thus it may protect the lung tissue from injury induced by HCl,and the protective role of PHCD plus menchanical ventilation is superior to that of PHCD only.
