Objective To investigate the application of the double loop double button plate fixation on treatment of patients with complete acromioclavicular joint dislocation.Methods Twenty-six cases with Rockwood type Ⅲ complete acromioclavicular joint dislocation were selected as our subjects who hospitalized from Jan.2011 to Jul.2013 and underwent using dual loop button plate technology of double fixation and reconstruction of coracoclavicular ligament fixation.There were 19 males and 7 females.Their age ranged from 18 to 62 years old and average was 30.2 years old.Adopt Lazzcano standard score was used to evaluate the shoulder joint function.Results X-ray examination showed the acromioclavicular joint of all patients were fixed in right place.Shoulder function was back to normal after 1 to 2 months and no pain or mild pain were showed in some patients.Twenty-four cases were followed up for 6-24 months,and the average followed up periods was 18.2 months.According to Lazzcano standard score to assess the function of shoulder join.Twenty cases were excellent and 4 cases were in good.The excellent and good rate was 100％.Conclusion Dual loop button plate technique is proved to be a good approach in the treatment of complete acromioclavicular joint dislocation with small trauma,stable fixation.Meanwhile patients can perform early functional exercise and no recurrent dislocation without the need of internal re-fixation.

Objective To evaluate the administration of dinoprostone suppositories in induced labor for full-term pregnancy women with hypertensive disorders.Methods One hundred and nine full-term pregnant women admitted in Jiaxing Maternal and Child Health Care Hospital from February 2010 to December 2011 were included in the study.The subjects included 43 cases with pregnant hypertension (group A),36 cases with mild preeclampsia (group B),30 cases with severe preeclampsia (group C),and 30 full-term normal puerpera were also included (group D).Dinoprostone suppositories were placed in the vagina for induction.The cesarean delivery rate and perinatal prognosis were compared among the four groups.Results The cesarean delivery rate in group C was higher than other 3 groups; there was no significant difference among groups A,B and D.The rates of fetal distress and postpartum hemorrhage in group C were higher than those in other 3 groups; there were no significant differences in rates of fetal distress and postpartum hemorrhage among group A,B and D,while there was no difference in rate of neonatal asphyxia among all groups.Conclusion Dinoprostone is effective and safe in inducing labor for full-term pregnancy women with hypertensive disorders.

Postherpetic neuralgia (PHN) is a difficult medical issue and symptomatic treatment with medication is common. One case of PHN was cured by nerve avulsion and microtherm plasma nerve block. The male patient was 48-year-old with PHN on the right side of the nose, suffering recurrent pains within one year. The symptoms occurred irregularly and lasted for several minutes to hours every time. Electroacupuncture and Chinese medicine treatments in other hospitals made little efficacy. Physical examination showed skin of right side of the nose and nasal mucosa was normal and all laboratory reports confirmed negative. After microtherm plasma treatment in nasal cavity and corresponding area of nasal septum, the pain disappeared.

In order to observe the effects of pentoxifylline and povine iodine on preventing postoperative intestinal adhesions (POIA),the authors used eighty SD rats as the models of intestinal adhesions and divided them into four groups:control group,pentoxifylline group,povine iodine group,and combining drugs group Each group contained twenty rats The results showed that the adhesions of each group were different and the consequence of adhesive degree (from serious to slight) was control group,povine iodine group,pentoxifyllin group,and combining drugs group It is demonstrated that pentoxyfilline and povine iodine have significant effects on preventing POIA; and the combination of the two drugs can have a synergetic effect on POIA

The effects of sepsis on the liver include hypoxic hepatitis caused by ischemia and shock, liver cell damage caused by excessive inflammation, and cholestasis caused by changes in bile metabolism. Among them, cholestasis is a common complication in patients with sepsis. Cholestasis and jaundice in patients with sepsis are associated with an increased risk of infection, leading to an increased mortality rate. So far, the exact mechanism of sepsis with cholestasis is still unclear, so this article briefly reviews the mechanism of cholestasis during the early stage of sepsis.

Glutathione is an important component of the UW cold storage solution, but it is oxidized during storage. The experimental study has been carried out to determine the effect of air oxygen on stability of glutathione solution. The results of this study demonstrated that the main cause of decreasing concentration of sulfhydril glutathione is the air oxygen on surface of and within solution

The aim of this study was to establish stable expression of human thyroid stimulating hormone receptor (TSHR) alpha-subunit (hTSHRA) on human embryonic kidney 293T (HEK 293T). HEK 293T cell lines with stable expression of hTSHRA could be used for detecting affinity between hTSHRA and potential TSHR blocking-peptide. We firstly constructed hTSHRA gene into lentiviral vectors GV218. The sequence comparison indicated that we had constructed GV218-hTSHRAA. Western blot demonstrated the 52 kD aim band of hTHSRA on over-expressed HEK 293T cells. GV218-hTSHRA constructions and pHelper were then co-transfected into HEK 293T cells to form packaging plasmid. The HEK 293T cells that stably expressed hTSHRA could also express green fluorescent pro tein. The titer of lentiviral packaging vector is 2 x 10(8) TU/mL with qPCR. The lentiviral packaging vector thereafter was transfected into HEK 293T cells again. The hTSHRA expressed on the HEK 293T cells. Human TSHRA stab ly expressed on HEK 293T upon continuously passaging. Therefore, we established hTSHRA stable expression on HEK 293T cells by constructing GV218-hTHSR lentiviral packaging vector. It is a useful tool for studying TSHR affinity with anti-thyroid peptide.
