Objective To investigate the therapeutic effect of modified S-P approach without disconnecting the rectus femoris in patients with Pipkin typeⅠandⅡfractures. Methods The clinical data of 58 patients with Pipkin type Ⅰ and Ⅱfractures were retrospectively analyzed. Among the patients, 29 patients were treated with conventional S-P approach (conventional group), and 29 patients were treated with modified S-P approach (modified group). The incision length, operation time, bleeding, visual analogue score (VAS), postoperative complications and hip joint function at the final follow-up were compared between 2 groups. Results The patients of 2 groups had not incision infection, and showed primary. X-ray of 3 months after surgery showed fracture healing. There was no statistical difference in the time of follow-up between conventional group and modified group:(16.1 ± 5.2) months vs. (15.8 ± 5.6) months, P>0.05. The incision length, bleeding, VAS 3 d and 4 weeks after surgery in modified group were significantly lower than that in conventional group:(8.1 ± 0.8) cm vs. (12.3 ± 1.2) cm, (144.3 ± 16.5) ml vs. (172.4 ± 21.6) ml, (4.5 ± 1.1) scores vs. (5.9 ± 1.5) scores and (1.6 ± 0.7) scores vs. (2.4 ± 0.8) scores, and there were statistical differences (P<0.05). There were no statistical differences in operation time, VAS 3 months after surgery, incidence of postoperative complications and excellent and good rate of hip joint function at the final follow-up between 2 groups (P>0.05). Conclusions The modified S-P approach without disconnecting the rectus femoris is a better method in patients with Pipkin type ⅠandⅡ fractures, and it has the advantages of revealing more clearly, minimal invasion, lower bleeding and slight postoperative pain.

Ultrasmall superparamagnetic iron oxide (USPIO), as the contrast agent of MRI, possesses two major properties: long half time in the plasma and specific binding with macrophages. Compared with gadolinium, widely-used in clinic presently, USPIO has its unique advantages in diagnosis of central nervous system diseases, though which still need further clinical verification. This article reviews the application of USPIO in MRI diagnosis of some central nervous system diseases.

Aim To study the dopaminergic neuroprotection of quercetin-3-O-sophoroside and total flavonoids derived from Poacynum hendersonni in MPTP-induced mice model of Parkinson's disease.Methods To inject MPTP intraperitoneal to C57/bl6 mouse at 30 mg·kg~(-1)·d~(-1) 5 days for PD model preparation, qercetin-3-O-sophoroside(25 mg·kg~(-1))and total flavonoids(250 mg·kg~(-1))were treated through intragastric administration 7 days before.Watching the mice behavior change through autonomic activities and pole test after final treatment, dopamine content in striatum was determined with fluorescence photometer.The neurons pathological change in substantia nigra(SN)was observed by pafaffin slice and immunohistochemistry staining to analyze the dopaminergic neuroprotective effects of Poacynum hendersonni.Results Treatment of quercetin-3-O-sophoroside for 7 days in advance, can improve PD mice motivation and dopamine concentration in striatum, tyrosine hydroxylase immune-reactive neurons in SN increased as well.Conclusion Quercetin-3-O-sophoroside can attenuate the impairment of MPTP in mice model of PD.

According to years of treatment experience on herpes zoster,combined with its current onset characteristics as well as modem medicine,the authors probed into the relation between liver depression and herpes zoster on the following two aspects:one was liver depression and healthy qi (immunity) ; the other was liver depression and the incidence of herpes zoster.We considered that long-term liver depression impairs healthy qi.Then herpes zoster appears because detriment of healthy qi leading to decreased immunity,reactivation and reproduction of virus.Liver depression is a significant factor for the onset of herpes zoster.

From the view of medical professionals, this paper explored the standards of residents′ competency cultivation in Zhuhai using Delphi method. The research outcome that consisted of 53 factors and 6 dimensions was obtained after two rounds of expert consultation. There are 6 first-level indexes including professionnalism and body-mind quality, clinical practice skill, the competency of lifelong learning and self-improvement, humanistic medicine practice skill, medical knowledge, and the competency of promoting the medical system to develop. As well, there are 18 second-level indexes and 29 third-level indexes. The standards stated that the clinical prac-tice skill would not be the main part of residents′competency cultivation. Qualified residents should reach the na-tional standard of the clinical practice skill but also the other five indexes.

Objective To assess the disease severity and prognosis value by observing the kinetic change of serum procalcitonin(PCT)and PCT clearance rate(PCTc)in the patients with ventilator associated pneumonia (VAP). Methods A single-center prospective observational study was conducted. A total of 128 patients with VAP admitted into intensive care unit(ICU)of First Affiliated Hospital of Xinjiang Medical University from February 2012 to June 2014 were enrolled. The patients were divided into recovery group(n=88)and deterioration group(n=40) according to the therapeutic outcome. The acute physiology and chronic health evaluationⅡ(APACHEⅡ)scores were estimated within 24 hours when VAP was diagnosed. The serum PCT(PCT1,PCT5,PCT7,PCT9)and PCTc(PCTc5, PCTc7,PCTc9)were examined at 1,5,7 and 9 days after the VAP was diagnosed. The diagnostic and predictive performance of PCT,PCTc and APACHEⅡ scores were assessed by the receiver operating characteristic curve (ROC). Results APACHEⅡscores in recovery group were significantly lower than those in the deterioration group (14.49±5.30 vs. 18.90±5.30,t=-4.349,P=0.000). There was no significant difference in PCT level(μg/L)at 1 day after VAP was diagnosed between recovery group and deterioration group〔2.84(0.81,6.43)vs. 3.50(0.97,10.27), Z=-1.431,P=0.152〕. With prolonged treatment,PCT was gradually decreased in recovery group,while remained at higher level in deterioration group,which was significantly lowered at 5 days after VAP diagnosed in recovery group compared with that in the deterioration group〔1.28(0.65,3.13)vs. 2.39(0.78,9.35),Z=-2.012,P=0.044〕. PCTc maintained higher level in recovery group which was gradually increased with the improvement of the disease, and PCTc in deterioration group was lowered which was gradually decreased with the development of the disease. PCTc at 5,7,9 days in recovery group was significantly higher than that in deterioration group〔5 d:50.43(20.39,80.60)%vs. -56.68(-286.28,172.92)%, Z=-2.250, P=0.024;7 d:54.01(5.70,102.30)% vs. -76.91(-335.03, 181.21)%,Z=-2.561,P=0.010;9 d:63.88(25.93,101.80)%vs.-133.49(-547.20,280.16)%,Z=-3.133, P=0.002〕. The area under ROC curve(AUC)of PCT5,PCT7,PCT9 predicting the prognosis was 0.591,0.683, 0.746,respectively〔95% confidence interval(95%CI)was 0.456-0.726(P=0.161),0.557-0.808(P=0.005), 0.631-0.860(P=0.000)〕. When PCT9 was 5.65μg/L,the sensitivity of 95%and the specificity of 61%. The AUC of PCTc5,PCTc7 and PCTc9 was 0.648,0.685,0.729,respectively〔95%CI was 0.513-0.783(P=0.028),0.555-0.815(P=0.006),0.607-0.851(P=0.001)〕. When PCTc9 was 92%,the sensitivity was 98%and the specificity was 71%. The AUC of APACHEⅡscore was 0.693(95%CI 0.578-0.808,P=0.003). When APACHEⅡscore was 19.5,the sensitivity was 77%and the specificity was 58%. Conclusions The increased levels of PCT in patients with VAP were associated with the poor control of infection and may indicate the deterioration of VAP,it also can reflect the activity of lung infection in time. Keep observing the dynamic change of PCT and analyzing PCTc is more useful. The PCTc levels may provide evidence of disease progression and helpful in risk stratification in patients with VAP,and lower level of PCTc may accompany serious infection and predict poor prognosis.

To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.
