Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.

To explore the clinical characteristic and intervention strategies for pregnancy complicated with heart failure. The clinical data of 67 pregnant women with heart failure during January 1998 to December 2010 were collected and analyzed.The rate of heart failure in pregnancy with heart diseases was 31％ (67/216).The causes of pregnancy complicated with heart failure were peripartum cardiomyopathy ( n =33,49％ ) and hypertensive disorder complicating with pregnancy heart disease( n =28,42％ ).Heart failure in pregnancy appeared at an average of (36.0 ± 2.7 ) weeks.The average terminating time of pregnant women with heart failure was ( 36.5 ± 2.1 ) weeks.Cesarean section was the main safe choice of delivery for pregnant women with heart failure.The average weight of newborns for pregnant women with heart failure was(2517 ±541 )g.The rate of neonatal asphyxia was 22％ (11/50).Strengthening routine antenatal examination and treating pregnant complications timely can prevent and reduce the incidence of heart failure.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11％vs. 53.61％, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

Aim Toinvestigatetheroleofbrain-de-rived neurotrophic factor(BDNF)-tyrosine receptor ki-nase B (trkB ) signaling pathway in the therapeutic effects of ketamine on diabetic neuropathic pain.Meth-ods Forty-eightWistarrats,aged3months,weighing 200~250 g,were equally randomized into 4 groups(n=12 ):control group (C group ), saline group (S group),ketamine group (K group)and ketamine +ANA-12 group (KA group ).Rats in S,K and KA groups were intraperitoneally injected with a single of streptozotocin(STZ)65 mg·kg-1 to construct diabetic neuropathic pain model.After twenty-eight days,rats in S,K and KA groups were intraperitoneally injected with saline, ketamine 10 mg·kg-1 and ketamine 10 mg·kg-1 +ANA-12 0. 5 mg·kg-1 for consecutive 7 days, respectively. On the 8th day, mechanical withdrawal threshold(MWT)of rats was measured.Af-ter that,the rats were immediately sacrificed,and dor-sal ganglion of lumbar spine and prefrontal cortex (PFC)were harvested for measuring BDNF,p-trkB/trkB,synaptophysin and spine density by Western blot andglogistaining.Results ComparedwithCgroup, rats in S group significantly decreased MWT,BDNF, p-trkB/trkB,synaptophysin and spine density in dorsal ganglion and PFC (P <0. 05 ).Compared with S group,rats in K group showed a significant increase of MWT,BDNF,p-trkB/trkB,synaptophysin and spine density in the all observed regions(P<0. 05 ).On the contrary,rats in KA group showed a significant de-crease of MWT and BDNF,p-trkB/trkB,synaptophys-in and spine density as compared with K group in all regions(P<0. 05 ).Furthermore,BDNF was positive-ly correlated with spine density in all regions (P <0.05).Conclusion BDNF-trkBsignalingpathway mediates ketamine-induced therapeutic effects in dia-betic neuropathic pain.

Objective To compare clinical features,pulmonary functions,chest imaging and prognosis between combined pulmonary fibrosis and emphysema syndrome (CPFE) and idiopathic pulmonary fibrosis(IPF) without emphysematous changes in elderly patients.Methods 88 elderly IPF patients in Beijing hospital from January 2000 to October 2012 were divided into CPFE (n=30) and IPF (n =58) groups according to the CT imaging.Clinical features,blood gas analysis,pulmonary function,chest CT and survival time were compared between the two groups.Results 30 CPFE patients with the mean age of(75.5 ±7.6) years and 58 IPF patients without emphysema with the mean age of(73.7±6.8) years were enrolled.The proportions of male patients,smoking history and mortality were higher in CPFE patients than in IPF group(86.7％ vs.63.8％,28 vs.36,76.7％ vs.43.1％,x2 =5.09,9.74,8.98,P＜0.05 or 0.01).CPFE patients had a higher force vital capacity(FVC) and total lung capacity(TLC) as compared with IPF group [(2.6±0.9) L vs.(2.1± 0.5) L,(5.4±1.9) L vs.(4.4±1.1) L,t=2.69,2.35,P＜0.01 or 0.05].There were no significant differences in forced expiratory volume in one second(FEV1) and the diffusion capacity for carbon monoxide(DLCO) between the two groups.The main type of emphysema by HRCT scan were centrilobular emphysema in CPFE patients.There were lower median survival time in CPFE group than in IPF group [(3.0±0.2) years vs.(4.0±1.0) years,x2=4.50,P＜0.05].Conclusions The majority of elderly CPFE patients are males and smokers.The lung volume is increased in elderly CPFE patients as compared with IPF patients.Centrilobular emphysema is the primary type in CPFE patients.The prognosis is worse in elderly CPFE patients than in IPF patients.

This study was conducted to develop an optimal strategy to achieve long-term survival after a liver resection for a hepatocellular carcinoma by analyzing the actual survival of 54 patients who underwent liver resections at least 5 years ago. The mean age was 50.5 years with a male-to-female ratio of 5 : 1. The positive rates for HBsAg and anti-HCV were 60.4% (32/53) and 10% (1/10), respectively. Seventy-eight percent of the patients had co-existing chronic liver disease. Seventy percent of the patients had either TNM stage III or IV cancer. Fifteen patients (27.8%) survived longer than 5 years after the operation. The median survival time of the 54 patients was 27 months. Prognostic factors of statistical significance were the Child class, gross type and size of the tumor, intrahepatic metastasis, portal vein invasion, serosal invasion, tumor grade, TNM stage, radicality of the operation, cancer recurrence, and disease-free interval. Although the prognosis for the patients with tumors larger than 5 cm was poor, two patients whose tumors were larger than 10 cm with satellite nodules survived longer than 5 years after undergoing complete tumor removal. For the 26 cases with no intrahepatic metastasis, there was no survival difference between the lobectomy group and the segmentectomy/subsegmentectomy group (43% vs. 42%). In those cases with satellite nodules in one segment of the liver, 80% of the lobectomy group lived longer than 5 years while none of the patients in the less-than-lobectomy group survived long-term (p=0.0060). Cancer recurred in 77.8% of the patients. It was the main cause of late death after surgery. Eighty-one percent of the recurrences occurred within 2 years after the operation. Nearly all the recurrences developed in the remnant liver. Among 15 long-term survivors, 6 patients experienced recurrence between the periods of 26 and 76 months after resection. A total of 4 patients (9.5%) out of these 42 patients were subjected to repeat resection for the recurrent tumor. One of these four patients underwent a third resection for a recurrence after the repeat resection. Although the extent of hepatic resection turned out to be a prognostic factor of little significance overall, the recurrence rate of the lobectomy group tended to be lower than that of the less-than-lobectomy group among the subset of long-term survivors (p=0.0572). For long-term survival, a systematic segmentectomy/ subsegmentectomy is adequate for those tumors without intrahepatic metastasis, while the presence of satellite nodules in that segment mandates a standard hepatic lobectomy. For long-term recurrence-free survival, a hepatic lobectomy is probably needed, even for tumors with no intrahepatic metastasis.

This paper established a near-infrared spectroscopy quantitative model for simultaneous quantitative analysis of coptisine hydrochloride, dehydrocorydaline, tetrahydropalmatine, corydaline and glaucine in Corydalis Rhizoma. Firstly, the chemical values of the five components in Corydalis Rhizoma were determined by the reversed-phase high performance liquid chromatography (RP-HPLC) with UV detection. Then, the quantitative calibration model was established and optimized by fourier transformation near-infrared spectroscopy (NIRS) combined with partial least square (PLS) regression. The calibration model was evaluated by correlation coefficient (r), the root-mean-square error of calibration (RMSEC) and the root mean square of cross-validation (RMSECV) of the calibration model, as well as the correlation coefficient (r) and the root mean square of prediction (RMSEP) of prediction model. For the quantitative calibration model, the r, RMSEC and RMSECV of coptisine hydrochloride, dehydrocorydaline, tetrahydropalmatine, corydaline and glaucine were 0.941 0, 0.972 7, 0.964 3, 0.978 1, 0.979 9; 0.006 7, 0.003 5, 0.005 9, 0.002 8, 0.005 9; and 0.015, 0.011, 0.020, 0.010 and 0.022, respectively. For the prediction model, the r and RMSEP of the five components were 0.916 6, 0.942 9, 0.943 6, 0.916 7, 0.914 5; and 0.009, 0.006 6, 0.007 5, 0.006 9 and 0.011, respectively. The established near-infrared spectroscopy quantitative model is relatively stable, accurate and reliable for the simultaneous quantitative analysis of the five alkaloids, and is expected to be used for the rapid determination of the five components in crude drug of Corydalis Rhizoma.

Moderate to severe unilateral ptosis has previously been treated with levator resection or frontalis sling and cosmetic double fold in the opposite eyelid. This method often resulted in undesirable asymmetrical lid lag phenomenon in down gaze. From December 1991 to December 1994, we treated 65 cases of unilateral ptosis with frontalis sling or levator resection, and simultaneously cosmetic frontalis sling have been performed in the unaffected normal eyes of 41 patients and cosmetic double fold have been performed in the unaffected normal eyes of 11 patients. After 6 months of operation, authors survey the patients content. The number of cases of content were 4(36.36%) in 11 cosmetic double fold group and 31(75.6%) in 41 cosmetic frontalis sling group. The content after cosmetic frontalis sling was higher than cosmetic double fold. Asymmetrical lid lag phenomenon on downward gaze which is inevitable complication postoperatively was reduced by means of cosmetic frontalis sling of unafeected normal eye in unilatral ptosis. The authors expect that the patient will be more satisfied with the result of symmetrical lid lag in down gaze after cosmetic frontalis sling of unaffected normal eye in aesthetic aspect.
