Objective To investigate the emergency treatment measures of spontaneous frontotemporal intracerebral hematoma.Methods Retrospectively analyzed the rescue process and surgical experiences of 27 patients with spontaneous frontotemporal intracerebral hematoma combined with subarachnoid hemorrhage or ventricular hemorrhage.Twenty-three cases underwent surgery;4 cases with cerebral hernia under general anesthesia underwent craniotomy hematoma clearance,aneurysm clip and decompressive craniectomy;7 cases with previous history of hypertension,considered with hypertensive intracerebral hemorrhage,was performed with craniotomy hematoma clearance and decompressive craniectomy in the emergency under general anesthesia; 12 cases of middle cerebral artery aneurysms bleeding,chosen craniotomy hematoma clearance and aneurysm clip;4 cases found nothing by digital subtraction angiography (DSA) or CT angiography (CTA),were given conservative treatment,one of them was found arteriovenous malformations after 1 month,which was treated by γ-ray.Results After the surgery,2 cases died due to severe cerebral infarction,25 cases were followed up for 6 months,according to the Glasgow outcome scale(GOS) classification:17 cases with good prognosis,7 cases with poor prognosis,1 case with vegetative state.Conclusions Cerebral hernia formation in patients with spontaneous frontotemporal intracerebral hematoma should relieve cerebral hernia and mass effect as soon as possible,early surgery to save lives.Which of them without brain hernia,after diagnosis by CTA or DSA,choice suitable treatment.Sufficient preoperative evaluation,suitable surgical timing and good microsurgical techniques can improve the prognosis.

Objective To explore the relation between rheumatoid arthritis (RA) and the meteorological factors.Methods All RA cases in the group were followed for 12 months,patients were follow-up for every two weeks.In each followed-up,all RA cases were evaluated by the disease activity score-28 (DAS28) and the improved Jamieson questionnaire,and the correlation of the DAS28 and the average values of meteorolo-gical factors (temperature,humidity,atmospheric pressure,relative humidity,wind speed) by Pearson correlation coefficient.The moderate-severe activity cases were evaluated by chi-square test of different seasons.Results One hundred and eighty-eight cases completed the observation,One hundred and sixty-four cases were in moderate disease activities (x2=9.42,P=0.022).Sixty-eight cases were distributed in winter,which was significantly higher than other three seasons.The average temperature and wind speed was negatively related to the DAS28 (r=-0.743,P＜0.01; r=-0.576,P=0.003).Conclusion The activity of RA has the characteristics of seasonal changes,and is easily being aggravated in winter.Many factors may influence RA,including temperature and wind speed.Creating an appropriate micro-climate environment is beneficial for RA patients to reduce the disease activity.

Objective To evaluate the role of fetal brainstem-vermis (BV) and brainstem-tentorium (BT) angles in differential diagnosis of fetal cereballar vermis anomalies by three-dimensional ultrasonography. Methods A total of 335 normally developed fetuses at 18-34 gestational weeks were examined prospectively in Prenatal Ultrasound Center of Suzhou Municipal Hospital from July 2013 to July 2014 by three-dimensional ultrasonography scanning. The BV angles and BT angles were measured at the mid-sagittal sections of fetal heads which were obtained by three-dimensional ultrasonography. Sixteen fetuses with abnormal cerebellar vermis were selected. The BV angles and BT angles were measured and compared with the measurements of normal group. Results In normal fetuses, the mean of BV angles was (3.3±1.7)° , ranging from1.0 to 10.0°;the mean BT angle was (31.5±6.9)° , and ranging from 16.6 to 57.8° . In 16 cases of abnormal cerebellar vermis, 4 cases of Dandy-Walker Malformation (DWM) showed significantly upward rotated cerebellar vermises, the BV angles increased significantly (88.9±18.1)° , the cerebellar tentoriums were superior displaced, the BT angles increased remarkably (89.0±12.8) ° ;6 cases of Dandy-Walker variant (DWV) showed upward rotated cerebellar vermises, with increased BV angles (23.7±5.2) ° , and slightly increased BT angles (54.5±12.0)°;6 cases of Blake′s pouch cyst (BPC) showed upward rotated cerebellar vermises were, mildly increased BV angles (16.7±1.8)° , and slightly increased BT angles (50.3±8.2)° . The comparison results showed:BV angles increased with increasing severity of the condition in BPC, DWV and DWM;BT angles increased significantly in DWM. Conclusions The measurements of BV angles and BT angles are valuable in the differential diagnosis of fetal cereballar vermis anomalies. From 19 gestational weeks, a BV angle>60° is strongly suggestive of a Dandy-Walker malformation, while a measurement>10.0° and<20° favors the diagnosis of Blake′s pouch cyst.

Objective: To study the role of activating transcription factor 2 (ATF-2) in the growth of mandibular condyle cartilage. Methods: Primary chondrocytes of condyle were cultured. Expression plasmid of ATF-2 and plasmid bcl-2 promoter were transfected into chondrocytes. Luciferase assay and Western blot were used. Results: The absence of ATF-2 in mandibular condyle chondrocytes resulted in a decline in bcl-2 promoter activity, reduction in bcl-2 protein level. Conclusion: The results strongly imply that ATF-2 is required for adequate bcl-2 expression, and play a significant role in controlling growth plate chondrocyte progression.

OBJECTIVETo investigate the effect of Fructus psoraleae on the differentiation of cultured osteoblast MC3T3-E1 cell isolated from neonatal mouse's calvarium.

METHODF. psoraleae preparation was extracted with distilled water. A mouse osteoblast cell line MC3T3-E1 was used as a cell model for screening potency. Cultured MC3T3-E1 osteoblasts were divided into 4 groups: control and F. psoraleae extract 0.02, 0.2, 2 (crude drug) g x L(-1), change the medium and extract every 3 days. The content of ALP and type I collagen were measured. The expression of ALP, type I collagen and osteocalcin mRNA in MC3T3-E1 cell was detected by real-time PCR.

RESULTThe activity of ALP was stimulated by extract of F. psoralea at doses 0.2 g x L(-1), and the content of type I collagen was encouraged at doses 0.2 g x L(-1) . The extract of F. psoralea enhanced the expression of ALP, type I collagen and osteocalcin mRNA in MC3T3-E1 cell. The expression of ALP mRNA was enhanced by extract of F. psoralea at doses 0.2 g x L(-1) for 7-14 d, and the expression of type I collagen and osteocalcin mRNA was enhanced at doses 0.2 g x L(-1) for 14-21 days.

CONCLUSIONF. psoralea can stimulate the differentiation of osteoblasts in vitro. It will offer a reference for the active mechanism research.

Aim To explore the effects and mecha-nisms of choro-oxime derivatives on spatial learning and memory impairment in Kunming mice and SD rats induced by scopolamine and Aβ1-42 , respectively. Methods 40 Kunming mice were randomly divided into 5 groups: control group, model group, donepezil treatment group, arimoclomol treatment group and TCO-2 treatment group. There were 8 mice in each group. Mice of control group were established by intra-peritoneal injection of saline, and mice of other groups were injected with scopolamine and caused memory im-pairment. Both control group and model group were treated with solvent by intraperitoneal administration;donepezil treatment group received donepezil by intra-gastric administration; arimoclomol treatment group and TCO-2 treatment group were given the correspond-ing drugs by abdominal injection, respectively. The solvent and drugs were given at the same time every morning for 8 days. Spatial learning and memory abili-ty were tested by Morris water maze from the fifth day of the drugs administration. 40 SD rats were divided into 5 groups the same as the dementia model men-tioned above. Mice of control group were established by intracerebroventricular injection of saline, and mice of other groups were injected with insoluble Aβ1-42 to be induced of memory impairment. Solvent and drugs were also delivered as mentioned above. Morris water maze was carried out from the fifth day of the drug de-livery. After that, acetyl cholinesterase activity of hip-pocampus was tested with acetyl cholinesterase reagent kit; the content of Aβ1-42 in hippocampus was meas-ured by ELISA assay kit;the expression of phosphoryl-ated tau proteins was detected by Western Blot. Re-sults In both two dementia models, choro-oxime de-rivatives could improve the spatial learning and memory ability, shorten the escape latency and increase the times of crossing the former platform. Choro-oxime de-rivatives could also inhibit the acetyl cholinesterase ac-tivity in animal brain, decrease the concentration of Aβ1-42 and the expression of phosphorylated tau pro-teins in the dementia rats’ hippocampus. Conclusions Spatial learning and memory deficits induced by sco-polamine and Aβ1-42 could be reversed by choro-oxime derivatives. It may be concerned with enhancement of the cholinergic system functions and reduction of the levels of Aβ1-42 and phosphorylated tau proteins in the brain.

Objective: To investigate the influences of enteral and parenteral nutrition suppled by gut on the gut microecology of the rats with abdominal infection. Methods: 14 Sprague-Dawley(SD)rats with abdominal infection models made with cecal ligation and perforation method were divided into two groups: parenteral nutrition (PN group, n=7) and PN+enteral nutrition (EN group, n=7) . The components of nutrition solutions in the two groups were isonitrogen and isocaloric. The rats were killed in the sixth day. The feces in cecum were cultured for anaerobic bacterial growth and analysed by bacterial group DNA fingerprint spectrum with random amplified polymorphic DNA . Results: ①The total death rate of the rats was 69.6%. Abdominal cavity abscess, liver abscess, and pulmonary infection commonly appeared in the model rats. ②The number of germs cultured in EN group was higher than in the PN group, but the quantity of Cl Perfrigens was higher , too. The gene stripe of probiotics group in EN group was similar to that in normal rats showed in the DNA fingerprint spectrum, but was significantly different in PN group with strange stripes. Conclusion: Application of early EN may correct the intestinal flora disturbance resulted from PN and increase the quantity of intestinal flora, but it can't control the species and may increase some conditional pathogenic bacteria .
