Objective To explore the value of serum procalcitonin (PCT) for early evaluation of the severity in bacterial infection, and compare it with C-reactive protein(CRP), white blood cell(WBC) and temperature to understand their strengths and weaknesses. Methods A sample of 139 impatients with bacterial infection from July 2009 to June 2010 in our hospital were divided into four groups, including local bacterial infection group(Group A, n = 50), sepsis group(Group B, n = 51), severe sepsis group(Group C, n = 21) and septic shock group (Group D, n = 17) according to ACCP/SCCM consensus conference and the clinical manifestation. Twenty noninfectious patients during the same time were recruited as control(Group E, n = 20)PCT, CRP,WBC and temperature were evaluated in all patients before treatment and PCT were measured 5 days after treatment. Results During the early period of the bacterial infection, PCT was highest in Group D ([42.36±48.49] × 10-6 g/L),which was higher than that of (4.66 ±2.46) × 10-6 g/L in Group C,( 1.08 ± 0. 68) × 10 -6 g/L in Group B and (0. 09 ± 0. 05) × 10 -6 g/L in Group A(Ps ＜ 0. 05), PCT in the four infectious groups were all higher than the control group([0. 05 ± 0. 01 ] × 10-6 g/L)(Ps ＜ 0. 05). No significant difference in CRP between Group D and Group C, neither did between Group C and Group B (Ps ＞0. 05). No significant difference was found in WBC between Group D and Group C,neither did between Group D and Group B (Ps ＞ 0. 05). Temperature in Group D was not significantly different to Group C(P ＞ 0. 05). After 5 days' treatment, PCT decreased in the four infectious groups than before. Conclusion The level of PCT can be used to evaluate the severity of infection during the early period of bacterial infection, which is better than CRP,WBC and temperature. PCT decreases after effective treatment,which can help monitor the patients' condition.

ve To compare the advantage and disadvantages of spectrophotometry assay, microwave di-gestion and standard circumfluence method for determination of chemical oxygen demand (COD) in various water samples. Methods The levels of COD of the water samples were determined by spectro-photometry, microwave di-gestion and standard circumfluence method respectively. Results The relative standard variations were 4.3% ~ 9.59% for spectrophotometry, 3.58% ~5.61% for microwave digestion method and 4.03% ~ 4.27% for standard circumfluence method. The recovery rates of adding standard material were 90% -95% , 90% ~96% and 90% ~98% respectively. Conclusion The microwave digestion method showed easy, rapid and accurate. It presented good practical prospect in monitoring environmental samples.

BACKGROUND:The tensile and stress-relaxation mechanical properties of sciatic nerve injury after repaired with autologous nerve and poly(lactic acid-glycolic acid) (PLGA) scaffold are rarely reported. OBJECTIVE:To analyze the tensile and stress relaxation characteristics of sciatic nerve injury after the transplantation of autologous nerve and PLGA scaffold. METHODS:Sixty sciatic nerves were extracted from the fresh cadavers dead within 24 hours, processed into 35 mm samples, and were then randomly divided into three groups. The nerve samples in control group received no intervention;the nerves in artificial and autologous groups were modeled into 20 mm defects, followed by repaired with PLGA scaffold and autologous nerve, respectively. Afterwards, the tension and stress-relaxation tests were performed in each group. RESULTS AND CONCLUSION:The stress in each group descended fast at the first 600 seconds, then descended slowly and was closed to the horizontal level until 7200 seconds, and the stress-relaxation curves in each group were in logarithmic decrease. The order of the elastic limit load, elastic limit stress, maximum load, maximum stress, elastic limit strain and maximum strain during tension was as follows:control group>artificial group>autologous group (P<0.05). Our results indicate that the PLGA scaffold holds good tension and stress-relaxation properties, which meets the mechanical requirements of the biomaterials used for sciatic nerve repair.

OBJECTIVE:To investigate clinical efficacy and safety of goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing levonorgestrel intrauterine system (LIS). METHODS:A total of 140 adenomyosis pa-tients with severe dysmenorrheal were selected from Sanya Family Planning Technology Service Center during Jan. 2014-Jan. 2016, and then divided into control group and observation group according to lottery method,with 70 cases in each group. Both groups re-ceived LIS within first 7 d of menstruation,and observation group was given Goserelin acetate sustained-release implant 10.8 mg subcutaneously via anterior abdominal wall one week before placing. Therapeutic efficacy was evaluated 6 months later. The im-provement of dysmenorrhea was compared between 2 groups. The uterine volume,COX dysmenorrhea score (CMSS),menstrual volume,hemoglobin (Hb) and CA125 content were compared between 2 groups before and after treatment. The occurrence of ADR was also compared. RESULTS:The rate of dysmenorrheal improvement in observation group was 95.71％,which was signifi-cantly higher than 81.43％of control group,with statistical significance(P<0.05). Before treatment,there was no statistical signif-icance in above indexes between 2 groups (P>0.05). Compare to before treatment,CMSS score,menstrual volume and CA125 content of 2 groups were decreased significantly after treatment,while Hb content was increased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in uterine volume between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR(10.00％ vs. 14.29％)between 2 groups(P>0.05). CONCLUSIONS:Goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing LIS can effectively relieve dysmenorrheal,reduce menstrual volume and improve Hb and CA125 levels,but do not increase the risk of ADR.

Objective To study the relationship between cardiovascular diseases (CVD) and ischemia modified albumin (IMA) in patients with type 2 diabetes mellitus (T2DM).Methods Ninety-six patients with T2DM were selected as T2DM group retrospectively,and 60 cases of healthy physical examination were selected as control group,the patient' s medical history data were collected,the IMA was detected and Doppler ultrasound examination was performed.The relationship between serum IMA level and some laboratory parameters were analyzed.Results Twenty-eight cases (29.2％,28/96) occurred CVD among 96 cases of T2DM patients.The level of IMA in T2DM group was higher than that in control group [(58.25 ± 11.84) kU/L vs.(23.38 ± 6.41) kU/L],there was significant difference (P ＜ 0.05).The levels of IMA in T2DM combined with CVD group (28 cases) and T2DM not combined with CVD group (68 cases) were(91.46 ± 13.63),(47.91 ± 9.38) kU/L; the level of IMA in T2DM combined with CVD group was higher than that in T2DM not combined with CVD group and control group,there was significant difference (P ＜ 0.05).All patients completed echocardiography,Spearman correlation analysis between IMA and echocardiography indicators showed that the level of IMA was positively correlated with left ventricular end-diastolic diameter (r =0.546,P =0.031),interventricular septal thickness (r =0.427,P =0.039),posterior wall diameter of left ventricle at end-diastolic (r =0.582,P =0.026) and left venifieular mass index (r =0.339,P =0.042),and IMA was negatively correlated with ejection fraction of left ventricle (r =-0.561,P =0.024).Multivariable Logistic regression analysis showed that IMA,high-sensitivity C reactive protein,diabetes duration,fasting blood glucose levels were independent risk factors for CVD.Conclusions Serum IMA level is significantly higher in T2DM patients.IMA level is a related risk factor for CVD.
