Objective To study the diagnosis and treatment of the inappropriate antidiuretic hormone secretion(SIADH) syndrome after cerebral injury. Methods A retrospective analysis was conducted on 12 patients suffered from SIADH after cerebral injury. The clinical features were similar to common hyponatremia, no specific manifestation. Most of the hyponatremia were detected by routine examination. The first of all,sodium losing in these patients with hyponatremia was routine supplied according the amont of true salt losing.If natremia was not raised or still more descended 2～3 days after treatment, and amount of supplying salt was correspond to that of natriuresis, SIADH should be considered,using restricting water therapy,substituted for salt supplement.furosemide plus albumin were the first choice for dehydration therapy. Results 24～48h after restricting water and natrium, 12 patient's natremia level was back up in different degree. Except for 2 death whose natremia was not corrected completely, 8 patient's natremia was corrected completely in 1 week, 1 patient's in 14 days, and 1 in 3 months after injury. Conclusions Diagnosis of SIADH is very difficult before treatment, but effective treatment can be obtained if we adopt correcting strategy. In these patients, the diagnosis of SIADH was confirmed with the course of treatment,we call it as therapeutic diagnosis.

BACKGROUND:Intraocular refractive operation with phakic intraocular lens implantation has been used in highly refractive errors patients with over-high diopter and thinner corneal thickness, which has the advantages of reversibility and retain the eye's accommodation. OBJECTIVE:To evaluate the safety and stability of posterior chamber phakic intraocular lens implantation in comparison with Lasik correction for high myopia. METHODS:Total y 126 col ege students with high myopia, 63 males and 63 females, aged (21.87±1.18) years, were randomly divided into test and control groups. In the test group, col ege students received posterior chamber phakic intraocular lens implantation, while those in the control group were subject to Lasik correction. During 1-year fol ow-up, naked vision, corrected visual acuity, contrast sensitivity, and postoperative untoward reaction were observed, and the effectiveness and safety indexes were calculated in the two groups. RESULTS AND CONCLUSION:The effectiveness and safety indexes in the test group were both superior to those in the control group (P<0.05). After 1 year of fol ow-up, the contrast sensitivity light and dark environment in the test group was significantly improved, which was also higher than that in the control group. Decreased night vision and glare was found in five cases of the control group and one case of the test group. These findings indicate that posterior chamber phakic intraocular lens implantation is safe and effective that can improve the visual quality in clinic.

AIM: To investigate the inhibitory effects of genistein(Gen) on mouse allergic contact dermatitis(ACD).METHODS: The animal model of ACD was induced by DNFB.The effects of different doses of Gen on mouse ear swelling,body weight,histopathological changes in mouse ear skin,thymus index and spleen index were observed.RESULTS: All groups of Gen inhibited mouse ear swelling induced by DNFB significantly.The infiltration of inflammatory cells and thymus index were also reduced.However,the increase in mouse body weight was not affected.Low dose of Gen increased spleen index,high dose of Gen decreased spleen index.CONCLUSION: Genistein has significant inhibitory effects on mouse ACD induced by DNFB.

Objective To investigate whether transplantation of embryonic stem cell-derived cardiac myocytes (ESCMs) directly into the infarcted myocardium could improve the cardiac function in the rats.Methods Cell culture medium with or without ESCMs was injected into the borders of car- diac scar tissue one week after experimental infarction.Cardiac performance was evaluated 4 weeks later by means of echocardiography after ESCMs (n=16) or medium (n=12) injection.Results Im- munostaining confirmed the presence of?-actinin,?-MHC,and cTnI in the beating EBs.RT-PCR analysis of EBs revealed the expression of cardiac-specific genes,including cardiac Nkx 2.5,GATA-4 and?-MHC.ESCMs implantation significantly improved fractional shortening compared with medium- treated hearts (P

OBJECTIVETo explore the effect of half circle external fixation for the treatment of open tibial fractures.

METHODSFrom March 2005 to March 2011, 94 patients with open tibiofibula fractures were treated by closed manipulative or Kirschner-wire poking reduction with half circle groove external fixation including 63 males and 31 females with an average age of 39 years old ranging from 17 to 65 years old. Among these patients, 5 cases were cross shaped fractures, 19 were oblique form and spiral fractures, 70 cases were comminuted fractures. According to the fracture Gustilo classification, 49 cases were type IIIA, 45 were type IIIB. The incidence of wound infection, fracture healing time were observed. The function was evaluated according to the Johner-Wruhs standard.

RESULTSAll patients were followed up for 14 to 63 months (averaged 29 months). The wound healing time was from 16 to 39 weeks (means 21.4 weeks). No fracture nonunion, osteomyelitis and calf compartment syndrome occurred. The wounds of 81 cases were healed at the first period,deep wound infection occurred in 2 cases. According to the function Johner-Wruhs evaluation criteria:the result was excellent in 52 cases, good in 37 cases, fair in 5 cases.

CONCLUSIONClosed manipulative or Kirschner-wire poking reduction and half circle groove external fixation can reduce the infection rate of open tibiofibula fractures. For open tibiofibula comminuted fractures, after the half circle groove external fixation for 3 to 6 weeks, a middle Kirschner-wire was removed according to fracture end healing situation to make fixation dynamic and promote fracture healing.

The optimum conditions of baicalin hydrolysis into baicalein by immobilized beta-glucosidase in a two-phase system was studied and the yield was observed. A two-phase system comprising of sodium acetate buffer and chloroform was determined by comparing the solubleness of baicalein in different solvents and partition coefficient of baicalein in related aqueous-organic two-phase system. beta-Glucosidase was immobilized by the crosslinking-embedding method using sodium alginate as the carrier The optimum reaction temperature, pH value, Michaelis constant, the thermal stability and pH stability were assayed. By comparing the yield of baicalin hydrolysis into baicalein by immobilized beta-glucosidase in two-phase system, the optimum reaction conditions were determined-the optimum reaction temperature, pH value and time were 50 degrees C, 5.0 and 10 h, respectively. The yield of baicalein was 85.28%. Compare with one-phase system, two-phase system had an advantage in reaction rate and yield.

AIM: To study the suppressive effect of glycyrrhizin (GL), a Chinese medicine, on DNFB-induced contact hypersensitivity in mice. METHODS: BALB/c mice were divided into 5 groups according to different medication: GL 1 (11 mg/kg) group; GL 2 (22 mg/kg) group; GL 3 (44 mg/kg) group; dexamethasone (DXM, 0.75 mg/kg) group; and normal saline group. For induction of contact hypersensitivity (CHS) to DNFB, mice were sensitized to abdomen and challenged to right ear by epicutaneously DNFB. Each mouse was administrated intraperitoneally on day 1 to day 5 with different medication. The suppression of mice CHS by different medication were evaluated 24 hours after elicited, according to ear thickness difference, ear weight difference and pathological change of challenged ear section. Thymus index and spleen index were calculated to see the effect on mouse immune system to CHS. RESULTS: Compared with normal saline group, the ear thickness difference and ear weight difference were both significantly reduced in GL1, GL2, GL3 and DXM groups (P

Objective Myofascial pain syndrome (MPS) is a common muscle function disturbance.This study was to investigate the clinical value of acoustic radiation force impulse (ARFI) imaging in assessing the therapeutic effect of acupuncture for patients with trapezius MPS.Methods A total of 116 patients diagnosed with trapezius MPS received acupuncture therapy once a day for 10 days in Pudong Hospital from August 2015 to June 2016.Using ARFI imaging, we recorded the shear wave velocity (SWV) of the trapezius and obtained the short-form McGill Pain Questionnaire (SF-MPQ) scores of the patients before, at the end of, and at 7, 15 and 30 days after treatment.Then, we analyzed the interaction and correlation between the SWV values and SF-MPQ scores of the patients at different time points.Results Both the SF-MPQ scores and SWV values were first decreased, falling to lowest values (5.19 points and 1.43 m/s) at 7 days after treatment, and then increased again.The interaction between the SF-MPQ scores and SWV values were significantly different at different time points (Finteraction=2.553, Pinteraction=0.038), and there was a strong linear correlation between the two indexes (r=0.755, P=0.000).Conclusion ARFI imaging combined with SF-MPQ has a certain clinical value in assessing the effect of acupuncture on trapezius MPS.
