OBJECTIVE To study the clinical effect of preventing and treating sterile phlebitis(abacterial phlebitis,SP) by infrared irradiation after peripherally inserted central catheterization(PICC).METHODS Totally 122 inpatients from the Zhejiang Provincial People′s Hospital were divided into two groups randomly,the control group and the experimental group.The control group was only treated with usual care after PICC,while the experimental group with both infrared irradiation and usual care.The incidence rate of SP and its correlation factor were compared between the two groups.RESULTS None in the experimental group got SP.Nevertheless,the control group got a 21.9%incidence rate.The development of SP mostly own to impassable intubation or repeating intubation.CONCLUSIONS For those patients with impassable intubation or repeating intubation during PICC operation,infrared irradiation shows greatly helpful and can obviously prevent the SP and diminish patients′ fee.

Objective To investigate the correlation among mammographic features, and estrogen /progesterone receptor(ER,PR) of the breast cancer.Methods The mammographic features of 60 cases of breast cancer confirmed by surgery and histology were analyzed retrospectively. The specimens of mastectomy of the breast cancer were stained with immunohistochemistry,the expression of estrogen receptor (ER) and progesterone receptor (PR) were measured .The relationship between the immunohistochemical pathologic results and mammographic features were analyzed. Results Among the 60 cases of breast cancers, X-ray types mass of breast cancer were correlated with the expression of PR (P

Objective To clone express and purify Schistosoma japonicum fructose?1 6?bisphosphate aldolase SjFBPA in E. coli and observe its expression in different developmental stages of S. japonicum. Methods FBPA gene was amplified from S. japonicum adult worm cDNA by using PCR. The amplified product was recombined into pET28a plasmid and inducibly expressed with IPTG in E. coli BL21. SDS?PAGE and Western blotting were employed to analyze and identify the recombinant protein SjFBPA rSjFBPA . Then rSjFBPA was purified by chromatographic purification and its purity was analyzed by SDS?PAGE. The protein concentration of rSjFBPA purified was measured by the BCA method. Furthermore SjFBPA mRNA was ana?lyzed in different developmental stages of S. japonicum by RT?PCR. Results SjFBPA was successfully amplified by using PCR and identified by restriction enzyme digestion and sequencing. The Western blotting analysis confirmed that the recombinant pro?tein could specifically reactive to the anti?His?tag monoclonal antibody. The concentration of the purified recombinant protein was about 4 mg/ml. The result of RT?PCR showed that SjFBPA mRNA was expressed in cercaria schistosomulum adult worm and egg of S. japonicum. Conclusion SjFBPA is successfully recombined and expressed in a prokaryotic system and SjFBPA mRNA is expressed in cercaria schistosomulum adult worm and egg of S. japonicum.

Objective To discuss the value of diagnosing gastrointestinal dysfunction in.critically ill children.Methods Seventy-six critically ill patients were reviewed,48 cases combined with gastrointestinal dysfunction.Plasma D-lactate,intestinal fatty acid binding protein(IFABP)of serum and urine were performed in all patients,detected the sensitivity and specificity,ealculated the area under the ROC curve (AUC).Results Plasma D-Iactate level≥9.63 mg/L had a sensitivity of 85.2%,specificity of 70.9%,and AUC of 0.822 for diagnosing gastrointestinal dysfunction.Serum IFABP level≥0.129μg/L had a sensitivity of 65.2%,specificity of 63.8%,and AUC of 0.744 for diagnosing gastrointestinal dysfunction.Urine IFABP ≥0.330μg/Lhad a sensitivity of 78.3%,specificity of 72.3%,and AUC of 0.820 for diagnosing gastrointestinal dysfunction.There was no significant difference in AUC between plasma and urine IFABP(P＞0.05),there was no significant difference in AUC between serum D-lactate and serum IFABP(P＞0.05).Conclusions Plasma D-Lactgte,serum and urine WABP may be useful markers as warning gastrointestinal dysfunction of critically ill children.Plasma D-lactate and urine IFABP level may be more sensitively,but they need to be further studied.

Objective To explore the significance of motor unit number estimation (MUNE) by using multiple point stimulating technique to evaluate patients with Hirayama disease (HD).Methods Multiple point stimulating technique was used to estimate the motor unit number of abductor pollicis brevis and abductor digiti minimi in 35 normal subjects [14-33 years old,mean (20.9 ±4.0) years old,33 men and 2 women]without nerve and muscle disease and 69 patients definitely diagnosed as HD [16-35 years old,mean (21.46 ±6.61 ) years old,67 men and 2 women].The differences between the two groups were examined by Fisher's exact test and t test.Results There were 42 patients with atrophy and 27 patients with normal clinical manifestation of left hand.For right hand there were 54 patients with atrophy and 15 normal.For controls,the MUNE value of left abductor pollicis brevis was 226.97 ± 30.59,while that of right side was 22g.31 ± 25.35.The MUNE value of left abductor digiti minimi was 237.43 ± 30.78,while that of right side was 240.20 ± 37.73.For HD patients,the MUNE of left abductor pollicis brevis and abductor digiti minimi was 145.66 ± 126.10 ( t =5.07,P ＜ 0.01 ) and 102.20 ± 112.67 ( t =9.31,P ＜ 0.01 )respectively,while those of right hand was 149.72 ± 117.80 ( t =5.31,P ＜ 0.01 ) and 64.23 ± 69.27 ( t =16.76,P ＜0.01 ) respectively.MUNE of left abductor digiti minimi in 17 patients that was below 200 among 27 patients with normal clinical manifestation (x2 =9.57,P =0.002).MUNE of right abductor digiti minimi in 12 patients that was below 200 among 15 patients with normal clinical manifestation ( x2 =4.64,P =0.03).Conclusions The differences of MUNE values by multiple point stimulating technique between the normal subjects and the HD patients is significant,which suggests this method is very useful to evaluate HD in the early state.

【Objective】 To study the expression of leptin mRNA in Chinese obese subjects using dot blot hybridization with a digoxigenin labele d probe. 【Methods】 11 Chinese nonobese subjects (bodymass index, BMI 21.0 kg/ m2±1.5 kg/m2) and 12 Chinese obese subjects(BMI 28.5 kg/m2±2.3 kg/m 2) parti cipated in the study. The human leptin cDNA probe was labeled wih digoxigenin(DI G) b y the random priming method. Expression of leptin mRNA in abdominal adipose tiss ue has been examined using dot blot hybridization with this probe. 【Results】 T he expression of leptin mRNA was significantly higher in obese subjects than in non-obese ones (312.8±108.9 vs 175.9±81.5, relative units, P<0.0 5), an d correlated with BMI (r=0.56, P<0.05). 【Conclusions】 Leptin mRNA le vel is high in obese subjects, and correlated with BMI.

[Objectives]To investigate the protective effects of recombinant Trichinella spiralis excretory-secretory 53ku pro-tein(rTsP53)on acute lung injuries in mice.[Methods]Thirty Balb/c mice were randomly divided into normal group. ALI group and rTsP53 group(n=10,respectively). Macrophages were harvested by bronchoalveolar lavage. Mortality in 72 hours was counted and compared. Pathological damage of lung tissues was observed by HE staining and graded by Smith score. Wet/dry ratio was measured. The bronchoalveolar lavage fluid concertration of IL-6 and IL-4 was measured by ELISA. The mRNA expression of TNF-α,iNOS, IL-10 and Arg-1 in alveolar lavage macrophages was detected by RT-PCR.[Results]72 h mortality of ALI mice was 70%,which was reduced to 30% in mice received rTsP53 treatment. Compared with ALI mice,the pathological damage of in rTsP53 treated-mice was improved and Smith score was declined ,combined with descending W/D ratio. IL-6 level of alveolar lavage fluid was elevated in ALI mice compared with normal group. And alveolar lavage macrophage was polarized to M2 sub-type,appeared as higher mRNA expression of TNF-α and iNOS and lower level of IL-10 and Arg-1. Bronchoalveolar lavage fluid concentration of IL-6 was declined and IL-4 was elevated in rTsP53-treated mice compared with ALI group. The macrophages of alveolar wash had higher mRNA expression of IL-10 and Arg-1,while lower level of TNF-α and iNOS,manifesting M2 polarization characteristics.[Conclusion]Recombinant T.spiralis P53 protein could protect mice from acute lung injuries induced by LPS via modulating M2 macrophage polarization,which play a role in depression of inflammatory reaction and tissue repairment.
