Objective To investigate the clinical application value of serum tumor markers CA72-4,CA125,CA19-9 and CEA in the diagnosis of colorectal cancer.Methods 4 serum tumor markers CA72-4,CA125,CA19-9 and CEA levels in 50 cases with colorectal cancer(group A),50 cases with benign colorectal lesions(group B) and 50 healthy subjects(group C) were determined by chemiluminescence immunoassay and then analyzed statistically.Results The CA72-4,CA125,CA19-9 and CEA in group A were (18.46 ± 1.28) μg/L,(81.20 ± 5.82) tμg/L,(90.34 ± 5.39) ku/L and (28.44 ± 2.65) μg/L,which were significantly higher than those in group B (t =8.21,8.82,7.99,8.42,P ＜ 0.05) and group C (t =9.01,9.65,9.21,9.62,all P ＜ 0.05) ; while the differences between group B and group C were not significant (P ＞ 0.05).The CA72-4,CA125,CA19-9 and CEA testing positive rates were significantly lower than combined detection (x2 =7.62,9.04,7.79,6.05,all P ＜ 0.05).Conclusion Serum tumor markers CA72-4,CA125,CA19-9 and CEA in the diagnosis of colorectal cancer have important clinical significance,and the combined detection can improve the accuracy of diagnosis of colorectal cancer,which has better clinical value.

AB; and there is not obvious difference in the TLC of 2 kinds of extraction liquid, but there is difference in the GC of volatile oil in them. Conclusion: It is the best combination to extract Rhizoma Coptidis and Cortex Cinnamomi seperately.

WAE. Conclusion SBE method is better than the other three methods in the extraction of Jiaotai Pill components.

Objective:To optimize the extraction condtions in the modification of the formula of Jiaotai Pill. Methods: The semi bionic extraction (SBE) conditions were optimized through homogeneous design while berberine, cinnamic acid, total alkaloids, volatile oil and dry extract were adopted as markers. Results: PH in first extraction was adjusted to 2.20 by the use of HCL solution. And then PH in second and third extraction adjusted to 6.50 and 7.80 , duration of run was 170 min, 80 min and 40 min, respectively. Conclusion: Semi bionic extraction in Jiaotai Pill is approximated to theoretical extraction value.

Objective To investigate the clinical curative effects of duloxetine combined with thioctic acid on diabetic painful peripheral neuropathy. Methods Sixty-two patients with diabetic painful peripheral neuropathy were divided into three groups by random digits table: group A(22 patients, duloxetine combined with thioctic acid group), group B (20 patients,duloxetine group) and group C (20 patients,thioctic acid group). The other treatments were same. All patients were treated for six weeks. The pain remission level and nerve conductive velocity were compared among three groups. Results The pain level in three groups was significantly alleviated after treatment (P ＜ 0.01 ). The general effective rate was 86.4%(19/22),70.0% (14/20) and 50.0% (10/20) in group A,group B and group C,respectively (P ＜ 0.05). Visual analogue scales (VAS) in group A was significantly lower than that in group B and group C from the second week after treatment (P ＜ 0.05 ). Nerve conductive velocity was improved in both group A and group C after treatment (P＜0.01),but there was no significant difference between two groups (P＞0.05). In group B,compared with that before treatment,nerve conductive velocity had no significantly improved after treatment (P＞ 0.05). Conclusion Duloxetine combined with thioctic acid can enhance the clinical curative effects on diabetic painful peripheral neuropathy.

Objective To analyze the clinical features of the hospitalized children with laboratory-confirmed influenza in Suzhou. Methods The demographic information, laboratory test results, clinical features, treatments and outcomes of the hospitalized children with laboratoryconfirmed influenza were collected retrospectively. The data were analyzed using chi square test,Cochran-Armitage trend test. Results Four hundred and eighty hospitalized children were diagnosed with laboratory-confirmed influenza during the period of 2005 to 2009. Among these cases, 414 were subtype A and 66 were subtype B. The positive rate was 2.66%. Four hundred and nineteen cases (87.29 %) were ≤ 5 years old. Most of the cases developed during winter (from December to April the next year) and summer (from July to August). The age and sex distribution didn't vary from year to year (x2=9. 7768,x2 = 8. 7573; both P＞0.05). The mean disease course was (16.22± 9.41)days, and the mean hospitalization duration was (7.89 ±2.97) days. The percentages of patients with symptoms of fever, dyspnea and diarrhea or requiring oxygen treatment decreased with age (Z =4. 9430, Z=2. 1021, Z=3. 2073 and Z=2. 3277, respectively; all P＜0.05). The percentages of cases with concomitant pneumonia and upper respiratory infection also decreased with age (Z =-3. 8762 and Z=-3. 5095, respectively; both P＜0.01). Fifteen point five percent (60/387 cases)of the cases were co-infected with pneumococcus and 15. 0% (72/480 cases) were co-infected with respiratory syncytial virus (RSV). The level of C-reactive protein was significantly higher in cases with bacterial co-infection than those with viral co-infection (Z= -3.1290, P ＜ 0. 01 ).Conclusions Hospitalized children with influenza are more common in winter and summer in Shuzhou.Many patients are co-infected with pneumococcus or RSV. The symptoms are more severe in younger children.

Objective: The extract technologies for the components of Fuzhuang Capsules were optimized. Methods: Four methods: the semi bionic extraction (SBE), the water extraction (WE), the semi bionic extraction by precipitation with alcohol (SBAE) and the water extraction by precipitation with alcohol (WAE) were used to extract Fuzhuang Capsules, with panaxadiol, panaxatriol, ? sitosterol, icariine, betaine, total sugar and dried extractive taken as the marker, under the same conditions of drug granularity, solvent amount, decocting temperature, filtration, concentration, etc., and then four methods were compared and studied. Results: Through the comprehensive evaluation of seven markers, their comprehensive values Y decreased in the order of SBE, WE, SBAE and WAE. Conclusion: SBE is better than the other three methods in the extraction of the components of Fuzhuang Capsules, which is showed by the fact that the pH values of the water for the 1st, 2nd and 3rd decoctions are 3.4, 7.5 and 8.4, and the extraction times are 2.0h, 1.5h, and 1.5h respectively.

Objective Severe preeclampsia (sPE), which is usually complicated by small-for-gestational-age (SGA) and immature labor , remains a leading cause of maternal and neonatal mortality and morbidity. This study was to investigate the risk factors of SGA in sPE. Methods We retrospectively analyzed 100 cases of sPE, 35 with SGA (the case group) and the other 65 without it ( the control group ) .We conducted single-factor analysis on the general characteristics and potential impact factors of the patients , i-dentified the independent risk factors of SGA using the un-conditional stepwise logistic model , and assessed the value of umbilical arter-y S/D ratio and proteinuria ration in the diagnosis of sPE with SGA with the ROC curve . Results Compared with the control group , the case group had more cases of early-onset sPE ( P =0.010 ), earlier gestational and delivery weeks (P<0.001), lower neonatal weight at birth ( P<0 .001 ) , higher rate of admission to and longer stay in the neonatal ICU (P<0.001), and higher incidence of neo-natal complications (P<0.05).The case group also showed signifi-cant increases in comparison with the control in the umbilical artery S/D ratio (2.95 ±0.75 vs 2.31 ±0.47, P<0.05), frequency of S/D ratio ≥95th percentile (22.86% vs 6.15%, P<0.01), and rate of proteinuria ≥5 g/24 h (42.86% vs 20.00%, P<0.05).The S/D ratio ≥95th percentile (OR=6.02, 95%CI:2.32-16.78) and proteinuria≥5 g/24 h (OR=1.65, 95%CI:1.56-3.01) were found to be the risk factors of sPE with SGA.The area under the curve was 0.852 for the combination of S/D ra-tio and proteinuria ration in the diagnosis of sPE with SGA (P<0.05). Conclusion Umbilical artery S/D ratio≥95th percentile and proteinuria ≥5 g/24 h contribute to the early prediction, prevention, and prognosis of sPE, and is valuable for the diagnosis of sPE with SGA.
