The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

Urinary brain-derived neurotrophic factor (BDNF),an ubiquitous neurotrophin,was found to rise in patients with benign prostatic hyperplasia (BPH).We hypothesized that the urinary level of BDNF could be a potential biomarker for lower urinary tract symptoms (LUTS) in patients with BPH.Totally,76 patients with BPH-caused LUTS and 32 male control subjects without BPH were enrolled.International Prostate Symptom Score (IPSS) was applied to assess the symptom severity of LUTS.Urodynamic tests were performed for the diagnosis of underlying detrusor overactivity (DO) in the patients with BPH.Urine samples were collected from all subjects.Urinary BDNF levels were measured using enzyme-linked immunosorbent assays and normalized by urinary creatinine (Cr) levels.Seventy-six BPH patients were divided into moderate LUTS group (n=51,7＜IPSS ≤ 20) and severe LUTS group (n=25,IPSS＞20) according to the IPSS.Of the 76 BPH patients,DO was present in 34 (44.7％)according to the urodynamic test.The urinary BDNF/Cr levels were significantly higher in BPH patients with moderate LUTS (8.29±3.635,P＜0.0001) and severe LUTS (11.8±6.44,P＜0.0001) than normal controls (1.71±0.555).Patients with severe LUTS tended to have higher urinary BDNF/Cr levels than patients with moderate LUTS (11.8±6.44 vs.8.29±3.635,P=0.000).The conditions of BPH with LUTS correlated with elevated urinary BDNF levels,and urinary BDNF levels were even higher in BPH-DO patients.The results of this study have provided evidence to suggest that urinary BDNF level test could evaluate the severity of LUTS in BPH patients,and BDNF level can be used as a biornarker for the diagnosis of DO in BPH patients.

Secondary metabolites are the result of that plant interaction with biological and non-biological factors in the long-term evolution process, and play an important role in plant growth, development and physiology. The effective components of medicinal plant are usually the secondary metabolites in plant cells, and the synthesis of them are affected by a variety of factors, such as environmental impact. Acquirement of the secondary metabolites via callus culture has the advantage of low cost and less environmental impact. The synthesis and accumulation of medicinal plant secondary metabolites are not only controlled by light, temperature and pH, but also infected by germplasm, plant growth regulator and elicitor. This article presents a review of the influencing factors, and provides a basis for further study and development.

OBJECTIVETo investigate the dynamic changes of the epididymal size 1 year after vasectomy.

METHODSFifty male volunteers received vasoligation. Before and at 1, 2, 3, 6, and 12 months after operation, we measured the size and detected the internal echoes of the epididymis using color Doppler ultrasonography.

RESULTSThe bilateral epididymides were both thickened post-operatively in all the 50 cases, with statistically significant differences between the baseline and the 1st month, the 1st and the 2nd month, the 2nd and the 3rd month, or the 3rd and the 6th month after surgery (all P < 0.01), but not between the 6th and the 12th month (P > 0.05).

CONCLUSIONWithin 6 months after vasectomy, the bilateral epididymides manifested a progressive thickening, but basically restored their balance of secretion-absorption after 6 months.

OBJECTIVETo investigate the effects of exposure of paraquat and maneb on the behavior, the morphology and electrical activity of the Substantia nigra and striatum, and to discuss the relationship between this two pesticides and Parkinson's disease.

METHODS37 rats were divided randomly into 3 groups: control group (n = 11), paraquat (10 mg/kg) group (n = 13) and combinative group of paraquat (10 mg/kg) and maneb (30 mg/kg) (n = 13), and were exposed twice a week for 6 weeks by intraperitoneal injection. The behavior of animals in the declined-plane, the vertical-grid and the open-field test were observed. The morphology of substantia nigral neurons were investigated by HE pathology. The spontaneous discharge of striatum neurons were recorded after exposure.

RESULTSCompared to the control group and the pre-exposure group, both the numbers of animals sliding down from the declined-plane and the latency of rats' moving on the vertical-grid significantly increased, and the animals' autonomic movement decreased significantly (P < 0.05, P < 0.001). After the combinative exposure, the neurons of the Substantial nigra pars compacta (SNPc) were progressively impaired, the cell density of the paraquat group [(82.17 ± 12.91) n/mm(2)] and the combined group [(41.15 ± 6.44) n/mm(2)] were lower than that in control group (143.10 ± 20.85 n/mm(2)] (P < 0.01). In the paraquat group (5.97 ± 7.30 Hz) and the combined group [(6.95 ± 9.87) Hz], the average discharge rates of the striatum neurons were increased significantly compared to the control group [(1.78 ± 5.05) Hz] (P < 0.01). The bursting discharge was increased significantly in the combined group (22.3%) compared to the control group (9.8%) and the paraquat group (5.6%) (P < 0.05, P < 0.01).

CONCLUSIONThe co-exposure of paraquat and maneb could induce similar symptoms to Parkinsonism syndrome of rats such as rigidity, moving reduction and etc, and the combined exposure had a certain enhanced effect compared to alone paraquat exposure. The combinative exposure of paraquat and maneb could cause neural loss in SNPc and it is involved with the enhanced electrophysiological activity in striatum. The synergy toxicity of paraquat and maneb in nigrostriatal system is related to Parkinson's disease.

OBJECTIVETo explore the effect of Scalp acupuncture on serum neuron specific enolase (NSE) and S-100β concentrations, and incidence rates of postoperative delirium (POD) and postoperative cognitive function (POCD) of elderly patients undergoing hip replacement.

METHODSEighty-four patients undergoing scheduled hip replacement under combined spinal-epidural anesthesia (CSEA) were assigned to the control group (group C) and the scalp acupuncture group (group S) according to random digit table, 42 cases in each group. In group S, scalp acupuncture was additionally performed according to International Standardized Scheme for Scalp Acupuncture. Scalp acupuncture was performed during the operation from the MS1 middle line of forehead [1 cun before Shenting (GV24), including Shenting (GV24)] and MS5 middle line of vertex [from Baihui (DU20) to Qianding (DU21), including Baihui (DU20) and Qianding (DU21)]. The operation time and post-operative length of stay were observed. The midazolam dosage, hemorrhage amount, fluid transfusion amount, urine amount, use rates of ephedrine and atropine during the operation were also observed and compared between the two groups. The occurrence rate of POD and POCD at post-operative day 3 (T₁), week 1 (T₂), month 3 (T₃), and month 6 (T₄) were measured. Eighteen patients were randomly selected to collect blood from internal jugular vein before anesthesia t₀), immediately after ending the surgery (t₁), 6 h after operation (t₂), 24 h after operation (t₃), and 48 h after operation (t₄), respectively. Serum levels of NSE and S-100β were correspondingly measured.

RESULTSThere was no statistical difference in the operation time, midazolam dosage used during the operation, hemorrhage amount, fluid transfusion amount, urine amount, use rates of ephedrine and atropine (P > 0.05). Compared with group C, the post-operative length of stay was shortened in group S (P < 0.05). The incidence rate of POD and that of POCD at each time point were lower in group S (P < 0.05). The expression level of NSE decreased at t₂, t3, and t₄, and the expression level of S100β also decreased at t₁, t₂, t₃, and t₄(P < 0.05). There was no statistical difference in expression levels of NSE or S100β between the two groups at other time points (P > 0.05).

CONCLUSIONScalp acupuncture could attenuate central nervous system lesion and improve POCD of elderly patients undergoing hip replacement.
