Objective To investigate the expression and clinical significance of fibroblast growth factor-2 (FGF-2) and human teclomerase reverse transcriptase (hTERT) in non-small cell lung cancer (NSCLC) tissues and analyze the correlation between them.Methods The expression of FGF-2 and hTERT were detected by immunohistochemistry in 90 NSCLC tissues and 20 non-lung carcinoma tissues.The correlation between the expression and clinicopathological features was also analyzed.Results The positive expressions of FGF-2(66.7％ ) and hTERT (75.6％) in NSCLC tissues were significantly higher than that in nonlung carcinoma tissues (15％ and 20％,respectively),P ＜0.01.The expression of FGF-2 and hTERT were significantly related to TNM stages and lymph node metastasis (P ＜ 0.01 ),but not to histological types,sex and age of NSCLC patients ( P ＞ 0.05 ).A positive correlation was found between the expressions of FGF-2 and hTERT in NSCLC(P ＜ 0.01 ).Conclusion The expression of FGF-2 and hTERT in NSCLC,which can be regarded as important references for prognosis of NSCLC,play important roles in the initiation and development of NSCLC.

Objective To observe age-dependent feature of damage of hippocampus to different maturational stages rats after kindling repeated seizures.Methods The effects of 5 daily pentylenetetrazol-induced convulsions in different rats beginning at postnatal day 10,20,60(P10,P20,P60)were evaluated.In the 3 groups,Thionin staining method was utilized to observe morphological changes and cell counting of dentate granule cells,CA3,CA1,and hilar neurons.Timm's method of silver sulfide staining was adopted to observe the mossy fiber sprouting.Results 1.Cell counting of CA1,CA3 and hilar neurons in P10 and P20 groups demonstrated no differences from controls in rats,whereas P60 with daily seizures had a significant decrease in CA1,CA3 neurons(8.22?1.88,5.62?1.68 vs 6.31?1.50,3.62?1.40)(t=2.246,2.587 Pa

Objective To investigate the effects of nutritional support on the hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection. Methods Twenty-nine patients with digestive tract fistula complicated with severe abdominal infection were administered parenteral nutrition (PN) for 4 to 8 days, and then followed by enteral nutrition (EN) or EN + PN. The body weight, serum albumin, transferrin, prealbumin, fibronectin were monitored before and on the 10th and 28th day after nutritional support. Results The levels of serum prealbumin and fibronectin were increased significantly on the 10th day after nutritional support (t = 3.72, 3.52, P <0.01). The body weight, the levels of serum albumin, transferrin, prealbumin and fibronectin were significantly higher than those before nutritional support (t=3.97, 6.57, 7.09, 3.51, 3.58, P<0.01). Conclusion Nutritional support is effective in alleviating hypermetabolism of patients with digestive tract fistula complicated with severe abdominal infection.

The association of polymorphisms of calcium channel?1 subunit ( Cav1.1 ) gene ( - 1551T/C at exon 11 ) with thyrotoxic periodic paralysis (TPP) was investigated by PCR-RFLP.The distributions and frequencies of - 1551TC + CC genotype and C allele in TPP group were significantly higher than those in hyperthyroidism (HT) and normal control (CON) groups.There was no statistic difference between HT and CON groups.Cavl.1 gene - 1551TC + CC genotype and allele may contribute to the development of TPP in male HAN population from North China.

Oral fluid resuscitation in early period of hypovolemic shock is an important measure in the treatment of casualties in the battlefield as well as in mass casualties in lieu of the means of establishing a venous line. The main tasks in the study of oral rehydration resuscitation are the proposition of appropriate prescriptions of the liquids to be given and methods of administration on the basis of a clear elucidation of the mechanism underlying the function of the digestive system in regard to transportation and absorption of the given ingredients. The aim of the study is to fully replenish maximal amount of fluid containing glucose and electrolytes in a convenient, expeditious, and effective way in a minimal span of time, in order to increase circulating blood volume. At the same time, ischemia and tolerance to oral fluids of the gastro-intestinal tract should be improved, electrolyte imbalance and incidence of secondary infection should be alleviated, and finally hypovolemic shock is corrected, so that the victim is kept alive and prepared for further definitive surgical intervention.

Purpose:To evaluate the feasibility of irradiat ion to the metastatic retroperitoneal lymph nodes using three-dimensional confo rmal radiotherapy (3-DCRT) and to assess the irradiation side effects. Methods:From Jun. 1997 to Sep. 2000, 52 patients of metastatic retroperitoneal lymph nodes were treated with 3-DCRT.These patients had receive d radical therapy for their primary tumors. 50 of them had been proved by pathol ogical examination. Radiotherapy was designed by Elekta company’s 3-D treatmen t plan. Dose volume histography (DVH) was used to verify and optimize the radiat ion plan. Using 5～6 conformal portals,the total irradiation dose was 40 Gy an d delivered at 4～5Gy per fraction every other day,to a total of 8～10 fractions in 16～20 days. The immediate responses and side effects were evaluated accordi ng to the WHO and RTOG criterion system. Results:According to Karnofsky criterion system the median scor e was raised 21.3. Three months after irradiation, the complete ,partial and tot al response rates were 38.6%(27/70), 54.3%(38/70)and 92.9%(65/70),respect ively. The early response was related to the target volume and pathological clas sification. The smaller the target volume, the better the response(? 2 = 1 5.211,P=0.004).The anaplastic carcinoma cases had better results than the squamous carcinomas and adenocarcinomas(? 2 =13.455,P=0.009).The 1- ,2- and 3- year survival rates were 59.6%(31/52)、23.1%(12/52)and 9.6%(5/ 52),respectively. Conclusions:Three dimensional conformal radiotherapy can be con sidered as an effective and feasible approach for the treatment of metastatic r etroperitoneal lymph nodes,and no serious complications were observed.

Objective To investigate the effective and inexpensive therapy to partial denture arches with seriously interlaced occlusion. Methods Occlusal reconstructions with fixed and removable prosthesis were taken to cure partial denture arches with seriously interlaced occlusion. Masticatory efficiency was measured and X-rays of Schillers position were taken before and after therapy. Results After therapy masticatory efficiency was raised. And the function of TMJ was better. Conclusion Occlusal reconstruction with fixed and removable prosthesis is an effective way to cure partial denture arches with seriously interlaced occlusion.

Objective To explore the application value of layered suture technique in laparoscopic common bile duct exploration with primary suture. Methods A total of 216 patients received laparoscopic common bile duct exploration with primary suture in our hospital from March 2007 to March 2013.Of these cases, layered suture technique was utilized in 89 patients and single-layer suture was used in 127 patients.The operation time, postoperative hospital stay, and postoperative complications were compared between the two groups. Results Two groups of patients were operated smoothly, with no conversions to laparotomy.Postoperative recovery was smooth.The operative time was not significantly different between the two groups of patients (t=-0.931, P=0.353). The postoperative hospital stay and incidence of postoperative bile leakage were significantly lower in layered suture group than those in single-layer suture group [(5.9 ±1.7) d vs.(7.7 ±1.8) d,t =7.400, P=0.000;3.4%(3/89) vs.20.5%(26/127), χ2 =13.167, P=0.000].In the single-layer suture group, the incidence of postoperative bile leakage was significantly higher in patients complicated with acute cholangitis [45.4%(10/22) vs.15.2%(16/105),χ2 =8.429, P=0.004], whereas in the layered suture group, the incidence of postoperative bile leakage was insignificantly different among patients with and without acute cholangitis [7.1%(1/14) vs.2.7%(2/75),χ2 =0.002, P=0.964]. Conclusion Application of layered suture technique in laparoscopic common bile duct exploration with primary suture is feasible and safe, with advantages of less bile leakage and shorter hospital stay.
