ObjectiveTo observe the effect of monosialo gangliosides-1 (GM-1) and Radix salviae miltiorrhizae (RSM) on neonatal hyposemic ischemic encephalopathy (HIE).Methods62 cases of HIE were randomly divided into treatment group and control group, and both groups received conventional therapy. Injection of RSM and GM-1 were added into the treatment group in 7～10 days therapy. ResultsHigh curative effect, average curative effect and total curative effect in the treatment group of 31 cases were 80.6%, 16.1% and 96.8%, while that in control group of 31 cases were 32.3%, 51.6% and 83.9% respectively. There was significant difference in the high curative effect and total effect between the two groups (P<0.05). ConclusionThe treatment combined with RSM and GM-1 can enhance the curative effect on HIE without any side effect.

BACKGROUND: Total isoflavones of pueraria (TIP) possesses estradiol-like structures and has inhibition effect on bone loss or osteopenia in ovariectomized rats. However, studies have demonstrated that the prevention and treatment effect of TIP on osteoporosis in ovariectomized rats is poor, especially in single utilization. OBJECTIVE: To investigate the combination effect of TIP and vitamin D on the treatment of osteoporosis in ovariectomized rats. METHODS: Totally 81 female sprague-drawly (SD) rats of 3-month-old were randomly assigned into 9 groups. Exception those in the sham-surgery group, all rats were prepared for ovariectomized models. Vitamin D or low-, middle- and high-dose TIP or low-, middle- and high-dose TIP combined with vitamin D were intragastric administrated in the vitamin D, TIP or combination groups, respectively. There was no drug medication in the model and sham-surgery groups. The uterus coefficient was calculated at 3 months after medication. The serum alkaline phosphatase (ALP) activity, calcium, phosphonium, bone gla protein, estradiol levels, as well as bone mineral density of femur was determined. RESULTS AND CONCLUSION: Compared with the model group, the uterus coefficient and estradiol level was obviously increased in the middle- and high-dose TIP groups and all combination groups (P < 0.05); the ALP and bone gla protein levels significant decreased (P < 0.05); and the bone mineral density of central and distal femur were notably increased (P < 0.05); in particular, the result was more manifest in the high-dose combination group. TIP and vitamin D presented with synergism in uterus coefficient, estradiol, ALP, bone gla protein levels and bone mineral density of distal femur, but the effect was not significant in the calcium and phosphonium levels in the TIP and/or vitamin D groups. The findings demonstrated that Tip combined with vitamin D can induce synergism on prevention and cure of osteporosis in ovariectomized rat.

Objective To investigate the imaging and clinical features of Percheron artery infarction.Methods The clinical manifestations,imaging data,treatment,and prognosis of 10 patients with Percheron artery infarction were analyzed.Results All 10 patients had acute onset and had different degrees of consciousness disorders,including vertical gaze palsy (n =3),language disorder (n =3),limb weakness (n =6),and memory impairment (n =4).MRI showed bilateral thalamus infarction.Midbrain V-sign in one patient was observed.Cerebral angiography revealed that one patient had Percheron artery infarction.All 10 patients were improved and discharged,but left with varying degrees of sequelae.Conclusions Percheron artery infarction is rare in clinical practice.The diagnosis is mainly based on clinical manifestations and imaging examinations.Cerebral angiography can diagnose the disease.

Objective To study the relationship of concentraions of trace elements and the SOD, GSH-Ps activities in plasma following severe burn injury, and provide witness for clinical treatment of trace elements disorder in burned patients. Methods The plasma and urine from 67 severely burned patients in our hospital were collected on day 2, 4, 6, 8, 10, 15, 20, 30 after hospitalization. Trace element levels were determined by atomic absorption spectrophotometry. The vital force of SOD and GSH-Px were measured in plasma with the kits provided by Nanjing Jiancheng bioengineering research institute. Results The ion concentration of Cu in serum got higher and that of Zn got lower after burn, but that of Mn, Se was of no significance. The concentration of Cu, Zn, Mn, Se in urine were increased. The enzymatic activities of T-SOD and Cu, Zn-SOD as well as GSH-Px decreased from the early period to the metaphase. Conclusion For a great deal of oxygen free radicals released by tissues, SOD and GSH-Px were consumed and their concentration decreased in early stage after burn. Due to the trace elements released into blood by destroyed tissues and their increased excretion from urine, tissues could not generate adequate antioxidase, resulting in weak ability against inflammation and poor tissue repair. Our result provides a theoretical clue for the replenishment of trace elements for severely burned patients in early and middle stage and offer a clue to pathology and etiological treatment of burn.

Objective To analyze the relationship between methylenetetrahydrofolate reductase (MTHFR)C677T,A1298C and methionine synthase reductase(MTRR)gene polymorphism with abnormal pregnancy history.Methods 549 normal women (control group)and 300 women with the abnormal pregnancy history(observation group)were taken as the subjects by adopting the case control research method.The oral mucosa epithelial cells were collected for extracting genomic DNA.The MTHFR and MTRR gene polymorphisms were detected by the gene sequencing method.Results The distribution frequency of MTHFR 677TT genotype in the abnormal pregnancy group was significantly increased compared with the control group (10.00% vs.3.46%,χ2 =15.25,P <0.01);the distribution frequency of MTHFR-1298CC genotype in the abnormal pregnancy group was significantly in-creased compared with the control group (11.00 vs.4.01%,χ2 =15.66,P <0.01);the distribution frequency of MTRR A66G gen-otype had no statistical difference between the two groups(χ2 =3.02,P =0.082).The interactive analysis of 2 genes indicated that simultaneous carrying the MTHFR A1298C mutation site and MTRR A66G mutation site increased the possibility of abnormal pregnancy occurrence (OR=1.52,P =0.011).Conclusion MTHFR C677T and A1298C have a certain correlation with female ab-normal pregnancy occurrence.

Objective To establish animal models in order to provide an experimental study basis for both the pathogenesis study and taking effective prevention scheme for doxorubicin extravasation injury. Methods A total of 20 Kunming mice for experiments on doxorubicin extravasation injury were divided in-to four groups, I.e., high dose group(2 g/L), medium dose group(1 g/L), low dose group(0.5 g/L) and the control group (injection with water). Dosages were administered with subcutaneous injection on both sides of mice abdomen. The adverse reaction of body, damage areas of extravasation injury, recovery period were observed and histopathologic slides of animal models on both 4 days and 11 days after experiment were performed and compared. Results No significant adverse body reaction was observed after injection for all groups. The damage areas due to extravasation injury were dosage and concentration dependent. In addi-tion, significant differences in recovery period were observed for mice in different groups, that is, the higher injection concentration and dose led to the longer recovery period. Results from the histopathologic study in-dicated that the putrescence of damage area was developed in high dose group mice, and the ulcer occurred after 4 d of dosage in medium dose group mice, respectively. In contrast, no ulcer was observed in low dose group mice. Conclusions It would be feasible to establish a prevention model for mice on doxorubicin extravasation injury by subcutaneous injection at a dosage of 0.05ml(1 g/L).
