ObjectiveTo explore the clinical effectiveness of intralesional glucocorticoid therapy on infantile hemangioma in proliferative stage,and variance of vascular endothelial growth factor(VEGF) expression in the hemangioma tissues.MethodsExperimental group:5 cases were injected with triamcinolone acetonide 3 days before operation,5 cases were done 6 days before operation,5 cases were done 9 days before operation and 5 cases were done 2 weeks before operation(the dose of injection was 1 mg/cm2 per time,but not exceeding 2 mg/kg).Control group:5 infantile hemangioma cases in involuting stage and 5 infantile hemangioma cases in proliferative stage did not received any therapy.The specimen of the hemangioma were collected to detect the expression of VEGF by two-step immunohistochemistry.Every optical slice was detected by 5 campus visualis of high power lens.ResultsObserving the specimen dyed by HE in the light microscope,there was no significant difference between injected group and non-injected group.But by means of immunohistochemistry,the expression of VEGF could been down regulation by the glucocorticoid(F=17.919 1P

Melanin is formed by oxidative polymerization of phenolic compounds,basically different kinds of melanin come from different organisms.DOPA melanin and DHN melanin have same physical and chemical characters although they have different biosynthetic pathway.DHN melanin is common in plant fungi and plays an important role on infection.The melanin accumulates in the fungal cell walls and prevents organic and inorganic molecules penetrating out,that insures appressorium's pressure and infection ability.This paper has reviewed the kinds and characters,especially discussed the role of melanin during pathogen infection based on our some research.

Armillariella tabescens EJLY2098 was induced to produce ?-mannanase with konjac fine flour (Amorphopallus rivieri) as single carbon source. This induced enzyme was then purified using DEAE ion exchange chromatography and named atMAN47. Zymologic analysis showed that the molecular weight of this ?-mannanase was approximately 47 kD. The enzyme was stable when pH ranged from 5.0 to 6.5 and could be activated by Na+ and Ba2+. With an optimal temperature of 50?C. Action mode analysis of TLC revealed that the enzyme belonged to the endo-?-mannanase family. Being a meta-acid endo-?-mannanase, it was suitable to be applied to feed industry with a promising future as an enzyme preparation.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

The cardiovascular circulation feedback control treatment instrument (CFCTI) is an automatic feedback control treatment system, which has the function of monitoring, alarming, trouble self-diagnosis and testing on the line in the closed loop. The instrument is designed based on the successful clinical experiences and the data are inputted into the computer in real-time through a pressure sensor and A/D card. User interface window is set up for the doctor's choosing different medicine. The orders are outputted to control the dose of medicine through the transfusion system. The response to medicine is updated continually. CFCTI can avoid the man-made errors and the long interval of sampling. Its reliability and accuracy in rescuing the critical patients are much higher than the traditional methods.

OBJECTIVETo investigate the effects of intensive insulin therapy on insulin resistance(IR) and serum proteins after radical gastrectomy.

METHODSTwenty-two gastric cancer patients were randomly divided into the control (n=11) and intensive insulin therapy group (n=11), and underwent distal radical subtotal gastrectomy under epidural anesthesia. Fasting blood glucose (FBG), fasting insulin (FINS) and serum proteins were assayed preoperatively and at day 1, 3, 7 postoperatively. Insulin resistance index was calculated using homeostasis model assessment (HOMA). The length of hospital stay and postoperative complications were recorded respectively.

RESULTS(1)The levels of FBG, FINS, lnHOMA-IR (P<0.01,P<0.05) and the incidence of insulin resistance were remarkably decreased by intensive insulin therapy after the surgical procedure.(2)The levels of serum transferrin (TRF), prealbumin (PRE) and retinal binding protein (RBP) in the intensive insulin therapy group were significantly improved as compared to control group after operation(P<0.05). (3) The duration of fever, antibiotic use, passage of gas by anus, length of hospital stay and the occurrence of postoperative complications were also significantly lower than those in control group(P<0.01,P<0.05).

CONCLUSIONCompared to routine therapy, the intensive insulin therapy has more beneficial effects on the patients undergone distal radical subtotal gastrectomy in decreasing the insulin resistance, improving the status of nutrition and preventing postoperative complications.

OBJECTIVETo investigate association of CD14-159C/T polymorphism with expression of leukocyte CD14 mRNA and plasma soluble CD14 (sCDI4) level in severe burn patients.

METHODSSeventy-seven patients with total burn surface area equal to or over 30% TBSA were hospitalized in the First Hospital Affiliated to the PLA General Hospital and Beijing You'anmen Hospital from June 2004 to June 2006. Blood samples were collected on 1st, 3rd, 5th, 7th, 14th, 21st, and 28th postburn day (PBD) for determination of CD14-159C/T polymorphism by PCR-subsequent restriction fragment length polymorphism (RFLP) analysis,plasma level of sCD14 and leukocyte CD14 mRNA expression were measured by ELISA and RT-PCR.

RESULTSFrequency of the T and C allele was 59.1%, 40.9%, respectively. Seven cases (9.1%) were homozygote (CC genotype), 49 cases (63.6%) were heterozygote (TC genotype), and 2 cases (27.3%) were TT homozygous allele,which reached the Hard-Weinberg equilibrium. Three cases with CC homozygote, 38 cases with TC heterozygote, and 15 cases with TT homozygous allele were complicated with sepsis, ending in MODS in 1, 19, 10 cases, respectively. Expression of leukocyte CD14 mRNA +/- 35, re- spectively), which were markedly higher than that in patients with CC homozygote during 7th-21st PBD (P < 0.05 or 0.01). The plasma level of sCD14 in patients with CC homozygote was significantly lower than that in patients with TC heterozygote on 5 PBD (85 +/- 46 microg/L vs 134 +/-43 mmicrog/L, P < 0.01), which were higher in patients with TC heterozygote and TT homozygous allele than that in patients with CC homozygote on 21st, 28thh PBD (P < 0.01). Conclusions In CD14 gene promoter-159C/T polymorphism, the gene and protein expression of CD14 in patients with TT, TC genotype are much higher than those in patients with CC homozygote. CD14 gene promoter-159 C/T polymorphism with TT homozygote may be one of the major markers in extensive burn patients in whom infection may progress to MODS. Compared with other genetypes, the incidence of MODS in sepsis patients with TT genotype increase markedly.

OBJECTIVETo explore the mid-term surgical results of arterial revascularization for femoro-popliteal arterial occlusive disease (lesion type C and D).

METHODSFrom January 2005 to February 2009, 191 arterial bypass had been performed on 170 patients (21 cases bilateral). There were 108 male and 62 female, age ranged from 45 to 85 years old with an average of 67 years old. The operative indication was claudication in 78 cases, rest pain in 62 cases, ischemic ulcer in 19 cases, and distal tissue necrosis in 11 cases. Arterial angiography were performed on all cases. According to TASC II document, type C lesions were seen in 127 limbs, type D lesions were seen in 64 limbs. Autogenous greater saphenous vein bypass in situ were done on 15 limbs, autogenous greater saphenous vein bypass reversed in 20 limbs, revascularization with artificial prosthesis in 128 limbs, composite grafts consisting of a prosthetic conduit with a distal venous segment in 28 limbs.

RESULTSThere were no 30-day mortality. Follow-up periods ranged 6 to 36 months with an average of (24 + or - 6) months. Seventy-three cases were lost during follow-up periods, follow-up rate was 57% (109/191). Primary patency rate was 84.4% (92/109). The patency rate was 88.2% with artificial prosthesis, 70.8% with greater saphenous vein (in situ or reversed). Secondary patency rate was 89.9%.

CONCLUSIONSArterial revascularization with artificial prosthesis is main treatment for diffused superficial femoral artery occlusive disease (TASC II type C and D lesion) with satisfied surgical results.

OBJECTIVETo observe the distribution features of tender points in knee of patients with knee osteoarthritis in order to provide evidences for the treatment and diagnosis.

METHODSFrom November 2011 to December 2012,86 patients with knee osteoarthritis were recruited, including 21 males and 65 females, ranging in age from 45 to 85 years old, with an average of (59.98 +/- 8.23) years old. The course of disease ranged from 3 months to 15 years. The tender points and its distributions were determined by finger press carefully on their knees. Data of studying was analyzed by frequency statistics and Hierachical cluster analysis.

RESULTSThe distribution of tender points in the knee osteoarthritis was mainly in the interior region and anterior area such as in apex of patella, adductor tubercle and et al. According to the results of hierachical cluster analysis, the tender points could be divided into two categories the first cluster was in the interior region of knee, the second cluster was in the lateral region.

CONCLUSIONThe findings demonstrated that cluster analysis statistical method can be used for classification of the distribution of tender points. The distribution features of tender points in knee osteoarthritis are related to the anatomic site in knee.
