Objective To explore the clinical characteristics of neonatal group B streptococcal sepsis (GBS)sepsis in order to provide the guide for early diagnosis and appropriate treatment.Methods A retro-spective review was performed and a total of 33cases of neonatal GBS sepsis were identified in the NICU of Children′s Hospital of Quanzhou from March 2011to October 2014.The perinatal factors,clinical characteris-tics,laboratory finding,treatment and prognosis were analyzed.Results A total of 33cases of neonatal GBS sepsis were identified.The incidence of neonatal GBS sepsis was 2.0‰(33/16448)among all the NICU pa-tients admitted at the same period.All 21cases of early-onset GBS sepsis were term infants,which had 13ca-ses of respiratory distress,11cases of anhelation and 10cases of cyanosis as main initial clinical symptoms. Among 12late-onset cases,8occurred in term infants,10with ardent fever as the main initial clinical symp-toms,6combined with purulent meningitis.All the GBS strains were sensitive to vancomycin,then penicillin combined with meropenem therapy was effective.Of the 33patients,18cured,9discharged with improve-ment,2died,4patients died during hospitalization after being given up because of serious complication,total mortality was 18.2%.Conclusion The clinical manifestations of neonatal GBS sepsis are usually obviously and fatally,and with a high mortality.Antepartum prophylaxis,early diagnosis and timely sensitive antibiotics therapy are vital for reducing the incidence of complications and mortality of neonatal GBS sepsis.

Curcumin is the main active component in turmeric, which possesses many pharmacologic effects, including anti-in-flammatory, antioxidant, anti-tumor, anti-atherosclerosis, liver and kidney protection and so on. However, due to its poor bioavail-ability, its clinical application is limited. Therefore, the methods for improving the bioavailability of curcumin were reviewed by refer-ring to a large number of literatures. The bioavailability of curcumin can be improved by different administration routes and various dos-age forms. The review provides theoretical basis and research ideas for the development of new drugs.

0.05). Conclusion IBS may be related to the changes of the serum level of PYY,but not to the changes of PYY receptor.

Objective To observe the changes of peptide YY (PYY) and its receptors in rats with ulcerative colitis (UC) by detecting both the serum level of PYY and jejunum epithelial cells in UC rats. Methods Rats were randomly divided into UC group, diarrhea-irritable bowel syndrome (D-IBS) group and control group. We measured the serum level of PYY by radioimmunoassay and made radioligand analysis of two basic parameters reflecting the characteristics of PYY receptors: dissociation constant (Kd) and maximum binding capacity (Bmax). Results The serum level of PYY was higher in UC and D-IBS groups than in normal group (P<0.001), and it was higher in UC group than in D-IBS group (P<0.001). However, the values of Kd and Bmax in UC group did not differ significantly from those in D-IBS and normal groups (P>0.05). Conclusion The serum level of PYY in UC group was significantly higher than that in normal group and D-IBS group; therefore, we assume that the change of serum PYY level may be related to not only the symptom of diarrhea but also inflammation. Kd and Bmax in neither UC group nor D-IBS group were significantly different from those in normal group, which indicates that the symptom and inflammation in UC may have nothing to do with the changes of PYY receptors.

Objective To evaluate the role of spinal c?Jun N?terminal kinase ( JNK ) signaling pathway in incisional pain in rats. Methods Sixty?three adult male Sprague?Dawley rats, weighing 200-250 g, were randomly divided into 3 groups ( n=21 each) using a random number table: incisional pain group ( IP group) , dimethyl sulfoxide ( DMSO) group, and JNK inhibitor SP600125 group ( SP group) . A 1?cm longitudinal incision was made through skin, fascia and muscle of the plantar aspect of the hindpaw in anesthetized rats. In group DMSO, 10% DMSO 10 μl was injected intrathecally at 30 min before surgery. In group SP, SP600125 25 μg (in 10 μl of 10% DMSO) was injected intrathecally at 30 min before sur?gery. Six rats in each group were sacrificed, and the mechanical paw withdrawal threshold ( MWT) and thermal paw withdrawal latency ( TWL) were measured at 24 h before establishment of the model and 2, 6, 24, 48 and 72 h after establishment of the model. After measurement of the pain threshold at 24 h before establishment of the model and 6, 24, 48 and 72 h after establishment of the model, the lumbar segment of the spinal cord was removed for determination of the expression of phosphorylated JNK ( p?JNK) by im?munofluorescence. Results The MWT was significantly lower, the TWL was shorter, and the expression of p?JNK was lower at each time point after establishment of the model than at 24 h before establishment of the model in group IP (P<0?05). Compared with group IP, the MWT was significantly increased, the TWL was prolonged, and the expression of p?JNK was down?regulated at each time point after establishment of the model in group SP ( P<0?05) , and no significant change was found in the parameters mentioned a?bove in group DMSO ( P>0?05) . Conclusion Spinal JNK signaling pathway is involved in the develop?ment and maintenance of incisional pain in rats.

Background Intraorbital implantation of coralline porous hydroxyapatite (CHA) is a favorable cosmetic method after enucleation.However,the low degree of vascularizatiou in implant results in implant infection and exposure.Studies showed that a collagen composite sponge treated by basic fibroblast growth factor (bFGF/ collagen composite sponge) can promote angiogenesis.However,whether bFGF/collagen composite sponge improves the vascularization of CHA implants is unclear.Objective This study was to investigate the accelerating effect of bFGF collagen composite sponge on vascularization of orbital implant made of CHA using 99Tcm-methylene diphosphate (MDP) scan.Methods Forty-five New Zealand rabbits were randomly assigned to 3 groups.Evisceration of eyeball was performed on the left eyes of rabbits,and naked CHA,collagen composite sponge wrapped CHA and bFGF/collagen composite sponge wrapped CHA were implanted into the orbit respectively in 3 groups.99Tcm-MDP of 3 mCi was injected in the rabbits via ear vein in 2,4,6,8 and 12 weeks,and the vascular enhancement intensity on implants was observed 3 hours after injection.The ratio of average radioactive count from the area of interest with the same size between the left eyes and the right eyes was calculated.The implants were extracted for histopathological examination in the 12 weeks.Results As the lapse of postoperative time,the inflammation response gradually disappeared and no exposure of implants was seen during the 12-week duration.A similar vascular development strength was found in the area of interest among the 3 groups 2 weeks after surgery.However,the vascular development was significantly enhanced in the left eyes compared the right eyes from 4 to 6 weeks,with the highest intensity in the 8th week in the naked CHA group and collagen composite sponge wrapped CHA group.In the bFGF/ collagen composite sponge wrapped CHA group,the strongest image was in the 6th week after operation.The ratios of average radioactive count between the left eyes and the right eyes were significantly higher in the bFGF/collagen somposite sponge wrapped CHA group compared with the naked CHA group and collagen composite sponge wrapped CHA group (all at P＜0.05),and ratios of average radioactive count of the collagen composite sponge wrapped CHA group was significantly higher than that of the naked CHA group (all at P＜0.05).New blood vessels ingrowed toward the center of the implants through the coralline porous under the optical microscope.Conclusions Both bFGF (20 μg)/collagen composite sponge and collagen composite sponge can accelerate the ingrowth of vessel in the CHA,but the promoting effect of bFGF collagen composite sponge is prominent.

Objective:To observe the changes of plasma oxytocin (OT), arginine vasopressin (AVP) and anxiety after exercise intervention in male opioids-dependent patients.Methods:Forty-five male opioids addicts who met the inclusion criteria and voluntarily participated in exercise rehabilitation were enrolled.According to stratified random sampling, all subjects were divided into exercise group ( n=22) and control group( n=23). Exercise group attended aerobic exercise combined with resistance training intervention, 5 times per week for 8 weeks.Aerobic exercise was mainly treadmill and elliptical, while resistance training was based on strength and endurance training.Subjects completed self-rating anxiety scale (SAS) and Chinese perceived stress perception scale (CPSS) before and after intervention, as well as physical fitness tests. Besides, plasma OT and AVP levels were detected.Independent sample t-test, paired sample t-test, and Chi-square test were conducted by using SPSS 20.0 software. Results:Before the intervention, there were no significant differences between the two groups in demography, drug history, SAS, CPSS, plasma OT and AVP(all P>0.05). The overall anxiety detection rate was 66.67%, the scores of SAS and CPSS were both higher than the Chinese norm, and the difference was significant(both P<0.01) . After the intervention, the levels of plasma AVP, the scores of SAS and CPSS in the exercise group (AVP(19.57±2.23)pg/ml, SAS(50.17±10.09), CPSS(36.59±6.36)) were significantly lower than those in the control group (AVP(22.53±2.56)pg/ml, SAS(57.12±12.00), CPSS(43.09±5.57), all P<0.05), and plasma OT((61.98±5.27) pg/ml) was significantly higher than that in the control group ((54.64±7.62) pg/ml)( P<0.01). Compared with baseline, maximal oxygen uptake(VO 2max), 1 min push-ups and sitting body flexion increased significantly in the exercise group (all P<0.05). Conclusion:Opioids drug addicts were prone to excessive stress and anxiety and other negative emotions in the process of drug withdrawal. Eight-week aerobic combined with resistance exercise changed the plasma OT and AVP levels of opioids addicts, effectively alleviated the perceived stress, improved the anxiety state and their health related fitness level.

Objective:To analyze relationship between 13q14 deletion and prognosis in initial-treatment patients with multiple myeloma (MM).Methods:The follow-up data of 121 patients with newly diagnosed MM admitted to the First People's Hospital of Xiangtan City from January 2012 to December 2016 were collected and divided into deletion group ( n=39) and non deletion group ( n=82) according to the deletion of 13q14.The prognosis situations were compared among patients with different 13q14 deletion. Univariate analysis was performed for 3-year overall survival (OS) and progression free survival (PFS) in patients with MM. Results:As of the follow-up time, the 3-year OS rate, 3-year OS, 3-year PFS rate, 3-year PFS and median PFS were 71.90%(87/121), 5.8-36 months, 47.93%(58/121), 2.3-36 months and 34.8 months, respectively. The age, hypoproteinemia, high lactic dehydrogenase (LDH) and 13q14 deletion were independent influencing factors of OS ( P<0.05). The age, high LDH and 13q14 deletion were independent influencing factors of PFS ( P<0.05). The 3-year OS rate and 3-year PFS rate in 13q14 deletion group were 61.54%(24/39) and 25.64%(10/39), lower than those in non-deletion group ( P<0.05). Conclusions:The short-term prognosis is poor in initial-treatment MM patients with 13q14 deletion. Conducting risk stratified treatment for patients based on common influencing factors of OS and PFS is conducive to improving their prognosis.

Objective: To investigate the expression of HSPC238 in cervical intraepithelial neoplasia and cervical cancer.Methods:We collected 76 cases of cervical cancer,105 cases of CIN and 28 cases of normal cervical epithelial.Then we inves-tigated the expression of HSPC238 by using immunohistochemistry and compared the significant differences between them.Results:There was no significant difference in the expression of HSPC238 between the cervical cancer and normal cervical epithelial ( Z=-0.242,P>0.05).However,there was significant difference between the cervical intraepithelial neoplasia and normal cervical epithelial (χ2=19.159,P<0.01) and the expression of HSPC238 was correlated with the grades of CIN.The expression of HSPC238 decreased when the grade of CIN was increasing.( rs=-0.327,P<0.01 ).Conclusion:The low expression of HSPC238 might be correlated with the development of cervical neoplasia.

Objective To explore the relationship between sudomotor function and peripheral artery disease (PAD),and to evaluate the effectiveness of sudomotor function testing to screen diabetic patients at high risk of PAD comparing to ankle-brachial index (ABI) and toe-brachial index (TBI).Methods A total of 263 diabetes mellitus (DM) outpatients in the 306th Hospital of PLA from August 2014 to April 2015 were enrolled in the study.ABI and TBI were measured by the Doppler method.Sudomotor function was evaluated by measuring the electrochemical skin conductance (ESC) of the hands and feet using the Sudoscan instrument.Cardiovascular autonomic neuropathy (CAN) was assessed and recorded as cardiac autonomic neuropathy risk-score (CAN-RS) by Sudoscan.Results ESC values of the feet and hands were positively correlated with ABI and TBI.The diabetes patients with abnornal ABI and TBI had significantly lower hand ESC [(45.63±12.87) μS vs.(68.10±17.40) μS,(59.17±19.58) μS vs.(68.57±17.11) μS;P＜ 0.05] and feet ESC [(44.54±25.48) μS vs.(70.92±19.46) μS,(59.21±24.52) μS vs.(71.71±19.02) μS;P＜ 0.05],and higher CAN-RS[(49.17± 15.41)％ vs.(36.33±16.25)％,(44.90±16.09)％ vs.(35.39±16.05)％;P＜ 0.05],than diabetes patients with normal ABI and TBI.Using ABI as the gold standard,the areas under the receiver operating characteristics (ROC) curve of the diagnostic performance of hands ESC,feet ESC and CAN-RS to identify PAD were 0.87,0.84 and 0.74,respectively (P＜0.001).Conclusion Sudomotor function testing can be helpful and beneficial to identify PAD in patients with diabetes.
