Objective To explore the reversion of astragaloside and NMDA receptor antagonist against the hyperphosphorylation of protein Tau induced by fetal intrauterine distress in neonatal rats.Methods The analysis of variance of factorial design was setted up two intervention factors which were fetal intrauterine distress (two levels:no disposition;a course of fetal intrauterine distress)and the drugs (three levels:iv Saline;iv astragaloside;iv MK -801).When the neonatal rats grew to 12weeks,the hippocampus was removed from the neonatal rats.Detected the content of glutamate in the hippocampus of rats by high performance liquid chromatography.The expression of protein Tau which includes p -AT8Ser202 and GSK -3β1H8 in the hippocampus of rats were detected by the methods of immunohistochemistry staining.Results Fetal intrauterine distress could significantly up -regulate the content of glutamate,which was not affected by MK -801,in the hippocampus of neonatal rats which was reduces by the astragaloside (P <0.05).And both influences presented subtracting effects (P <0.05).Fetal intrauterine distress and the drugs do not affect the total protein Tau in the hippocampus of rats (P <0.05).Fetal intrauterine distress could up -regulate the hyperphosphorylation of protein Tau in the hippocampus of neonatal rats which could be reduced by astragaloside and MK -801 (P <0.05).And the influences between fetal intrauterine distress and the drugs presented subtracting effects (P <0.05 ).Conclusion Our results indicate that fetal intrauterine distress reduce the hyperphosphorylation of protein Tau in neonatal rats though up -regulating the content of glutamate.GSK-3βis the key protein in this signaling pathway.

Objective: To approach a better solution for enhancing the therapeutic results of acupuncture therapy in the treatment of Tourette syndrome, by observing the clinical results of combined scalp with body acupuncture and mono-body acupuncture. Methods: Fifty-seven patients were randomized into a treatment group (31 cases) and a control group (26 cases). The patients in the treatment group all received combined scalp-body acupuncture treatment, while the patients in the control group were given mono-body acupuncture treatment, for 1 month as a treatment session. At the end of the third treatment session, the Yale Global Tic Severity Scale (YGTSS) would be compared between pre- and post-treatment. Results: In the treatment group, 2 patients were clinically cured, 4 showed markedly effective, 18 showed effective, and 7 failed, making a total therapeutic rate of 77.4%. In the control group, 0 were clinically cured, 3 showed markedly effective, 9 showed effective, 14 failed, making a total therapeutic rate of 46.2%. There was a significant difference between the two total therapeutic rates (P<0.05). Conclusion: The combination of scalp and body acupuncture had a better therapeutic result than the mono-body acupuncture therapy in the treatment Fifty-of Tourette syndrome.

OBJECTIVE:To investigate the clinical etiology,serum type and drug resistance of lung cancer complicated with pulmonary Haemophilus influenzae (Hi) infection,in order to provide reference for infection prevention and rational drug use. METHODS:Clinical data of 8025 inpatients with lung cancer complicated with pulmonary infection in our hospital from Jan. 2009 to Jun. 2016 were collected,and the clinical etiology of pulmonary Hi infection was analyzed. The slide agglutination method was used for serotyping,nitrocefin slip method was used to detect β-lactamase,K-B method was used for drug sensitivity test,WHO-NET 5.6 software was used to deal with the results of drug sensitivity test. RESULTS:Eleven factors as age,clinical classifica-tion,invasive operation,surgery,radiotherapy and chemotherapy,hospitalization time,use of broad-spectrum antibiotics or hor-mones and other were closely related to pulmonary Hi infection in lung cancer patients(P<0.05 or P<0.01). Among 8025 speci-mens,104 strains of Hi were detected with detection rate of 1.30%. Serum type NTHi accounted for 44.23%. Separable strains were mainly b type(22.12%),followed by f type(17.31%)and a type(11.54%). Among 104 strains of Hi,56 strains of β-lac-tamase were detected with enzyme-producing rate of 53.85%. Drug resistance of 104 strains of Hi to ampicillin,amoxicillin,com-pound sulfamethoxazole and chloramphenicol were all higher than 35%;drug resistance of Hi toβ-lactamase inhibitors,cephalospo-rins,carbapenems,azithromycin and other antibiotics were all lower than 20%. Drug resistance of β-lactamase producing stains to ampicillin,amoxicillin,compound sulfamethoxazole and chloramphenicol were all higher than those of non-producing strains,with statistical significance (P<0.01). There was no statistical significance in drug resistance to other antibiotics between producing stains and non-producing strains(P>0.05). CONCLUSIONS:The clinical etiology of pulmonary Hi infection in patients with lung cancer is complicated. The serum type of the isolate is mainly NTHi;enzyme production situation is not optimistic,but Hi keeps a low rate of drug resistance to most antibiotics. β-lactamase inhibitors,cephalosporins,carbapenems and azithromycin are first choice for the treatment of Hi infections.

Methods 21 consecutive patients with refractory ascites, 16 men and 5 women with mean age of 45 years (range 22-69 years) were followed up for an average of 337 days (range 50-1323 days). Asites/ abdomen circumference, serum parameters, stents function, time of followed up and survival rate were analized. Results The ascites was significantly reduced as compared with basal values (P

Objective To assess the clinical value of pre-operative embolization for nasopharyngeal angiofibroma. Methods 13 patients with nasopharyngeal angiofibroma confirmed by surgery and biopsy were retrospectively analysed. Bilateral carotid artery angiograpy was perfomed for demonstration of the arterial supply of tumor. According to the size and different caliber of arteries, embolization were seperately undertaken by different types of coil via 4.1or 5F Head-Hunter catheter. The embolization efficacy, embolization was evaluated by amount of blood loss. Results After coil embolization , no complication happened ranging 1～4 days (mean 2 days) in all 13 patients and then all the tumor masses were totally resected with mean blood loss of (584.6?379.4) ml (range 250～1500 ml). Conclusions Preoperative coils embolization is safe, reliable with less complication especially for reducing intraoperative blood loss and promoting the prognosis.

Objective To evaluate the efficacy and safety of caspofungin in the treatment of invasive fungal disease (IFD) in advanced age patients. Methods A retrospective analysis of the clinical data was conducted. IFD patients who had received caspofungin treatment in elderly wards were included. Results From January 2007 to August 2009, 29 IFD patients aged 80-100 years (mean 89 ) were treated with caspofungin. Except that one patient dead on the first drug administration day, there were 28 evaluable patients, 13 were cured (46.4%), 6 were markedly improved (21.4%), 3 progressed (10.8%) and 6 dead (21.4%). The overall effective rate was 67. 8%. Of 13cured patients, 12 were Candida bacreremia, 1 was Candida albicans disease of lung. Of 6 dead patients, 2 were Candida bacteremia, 1 was Candida albicans disease of lung and 3 was suspected of lung IFD. One patient performed that alanine aminotransferase was increased, considering drug-related impairment of liver function. Conclusions Caspofungin is effective and safe in the treatment of IFD in advanced age patients.

Objective To construct and evaluate the effects of 4C characteristic home health care services model on the health of puerperas and fetuses.Methods A total of 162 puerperas and neonates were recruited,assigned by random nember table to routine community care condition and 4C characteristic home health care condition matched on the type and degree of health condition as well as the puerperas' culture background.The health condition of puerperas and neonates were investigated and compared between the two groups 42 days after delivery.Results The incidence of breast bilges,cracked nipple,re-visit the doctor,re-admission,anxiety and depression were significantly lower in the home health care group than routine community care group [3.7％ (3/81) vs.23.5％ (19/81),2.4％ (2/81) vs.17.3％ (14/81),2.5％ (2/81) vs.16.0％ (13/81),1.2％ (1/81) vs.16.0％ (13/81),(37.35±10.72) scores vs.(41.73±10.55) scores,(39.53±13.19) scores vs.(43.94±13.44) scores,x2=21.753,18.378,8.890,11.259,t=2.621,2.108,P ＜ 0.05 or 0.01].The success breastfeeding rates,correct rate of related knowledge and master degree of newborn,self-nursing newborn skills and puerperas and relatives' satisfaction scores were significantly higher in the home health care group than routine community care group [71.6％ (58/81) vs.37.0％ (30/81),95.1％ (77/81) vs.59.3％ (48/81),91.4％ (74/81) vs.53.1％ (43/81),（92.31±3.61) scores vs.(89.83±5.43) scores,x2=21.202,29.506,29.569,t=3.423,P＜ 0.01].In additon,the rate of re-visit the doctor,re-admission and omphalitis were significantly lower in home health care group than the routine community care group [2.5％ (2/81) vs.13.6％ (11/81),6.2％ (5/81) vs.23.5％ (19/81),4.9％ (4/81) vs.22.2％ (18/81),x2=6.774,9.172,9.288,P＜0.01 or 0.05].Conclusions 4C characteristic home health care reduced the probability of breast problems and unhealthy emotions for the puerperas,reducing the severity of jaundice as well as omphalitis for fetuses,reducing the probability of re-visit the doctor and re-admission for the puerperas and neonates,which can increase patients' satisfactory and promoting the mothers and their families to master self-nursing and newborn nursing skills and the other related knowledge.

Aim To evaluate the effect of 15-hydroxy eicosatetraenoic acid(15-HETE) on the tension of isolated internal carotid artery(ICA) rings in normoxic or hypoxic rats in order to find out the pathophysiological effect of 15-HETE in ischemic/hypoxic brain tissues.Methods Sixteen healthy Wistar rats were randomly divided into two groups(n=8): group A with normal oxygen supply(FiO_2 21%) and group B with hypoxia(FiO_2 10%).9 days later,the rats were killed and the ICA rings were prepared.15-HETE in different concentration were added accordingly,and the after washing up,blockers of different kinds of K~+ channels such as 2 mmol?L~(-1) 4-AP,10~(-2) mol?L~(-1) TEA and 10~(-6) mol?L~(-1) GLYB were added to the KH solution separately,followed by the administration of 10~(-6) mol?L~(-1) 15-HETE.The isometric tension was recorded using a four-channel force-displacement transducer.Results The ICA tension was significantly increased both in groups A and B by 15-HETE in concentration-dependent manner(P0.05,n=8).Furthermore,10~(-2) mol?L~(-1) TEA,10~(-6) mol?L~(-1) GLYB had little effects on the tension of rings.Application of 10~(-6) mol?L~(1) 15-HETE after administration of TEA or GLYB induced nearly the same increase in ICA tone as it happened in the group administered with 10~(-6)mol?L~(-1) 15-HETE alone.Conclusion 15-HETE can induce brain vasoconstriction especially under the hypoxic condition.Voltage-dependent potassium channels play an important role in 15-HETE induced constriction.
