We only prolongated the course of shock from 2h to 5h, without predi- sposing the dogs. At 5h after hemorrhagic shock, the experimental results were asfollows: The ultrastructural damages were not only detected in the lung but also in theheart, liver, intestine and kidney etc. Major pathological lesions were: swelling of paren-chymal cells in various organs, vacular degeneration, and de-connection of cells. The laterwas shown as disintegration of hepatocyte-conjunction and disappearance of microvilli. Theorganelles of various cells ruptured to different degrees, for example, mitochondria swelledand its crista dissolved, endoplasmic reticulum dilated and de-granulated. In addition, thefibril of cardiac muscle thinned and dissolved, the capillary endothelial tight-conjunctionsof lung and intestine ruptured etc. The quantity of entero-endotoxin in plasma increasedin accordance with prolongation of shock, and its quantity was most abundant in portalvein, the next was artery and the last was hepatic vein. All experimental results showedthat the entero-endotoxin was related to the changes of ultrastructure of various organs.

Objective To construct a baculovirus expression vector for expression of human Ro60 cDNA. Methods Ro60 cDNA was cloned from Hela cell RNA with RT-PCR and was inserted into plasmid pFastBac HTc. Plasmid pFastBac HTc-Ro60 was then transformed into E. coli DH10Bac competent cells for transposition. The constructed recombinant was determined by both blue-white colony screening and PCR analysis. Results A 1.56kb Ro60 cDNA was obtained from Hela cell RNA and was successfully inserted to plasmid pFastBac HTc. DNA sequencing and restriction enzyme analysis revealed that both open reading frame and sequence of the cDNA were identical to Ro60 sequence previously published. Specific transposition and virus recombination were obtained in the vector Bacmid-Ro60. Conclusion Ro60 cDNA has been successfully cloned and constructed to baculovirus expression vector, which is useful for protein expression and further study of this autoantigen in the pathogenesis of lupus erythematosus.

Objective To study the effect of fluoride varnish on microconsistency of enamel after under irradiation in vitro. Methods Normal enamel samples were randomly divided into four groups: control group,irradiation group,fluoride varnish group and fluoride varnish-irradiation group.The microconsistency of enamel surface before and after treatment,after anti-caries test was measured by type MH-5 durometer. Results Fluoride varnish had an inhibitory effect on the decrease of enamel microconsistency etched with lactate buffer.The microconsistency in irradiation group was obviously lower than that in control group(P

Objective To investigate the prognosis of two subtypes of subacute cutaneous lupus erythematosus (SCLE). Methods Forty patients with subacute cutaneous lupus erythematosus were followed-up for 3 to 14 years. The clinical and laboratory findings, the response to treatment and the prognosis in these cases were comparatively analyzed. Results During the follow-up period, the patients with annular erythema subtype of SCLE showed recurrent annular skin lesions and mild systemic manifestations. Some patients gradually developed sicca symptoms. On the other hand, most patients with papulosquamous subtype of SCLE developed systemic LE manifestions. 21.7％ of the patients in the annular erythema group had mild nephritis which could be controlled by lower dose of corticosteroids and no patients died. However, 64.7％ of the patients in the papulosquamous group had moderate to severe lupus nephritis, which required higher dose of corticosteroids or immunosuppressive agents to control. Among them, One patient died and 3 patients developed uremia. Conclusion Annular erythema subtype of SCLE is milder and has a better prognosis than that of papulosquamous subtype.

[Objective]To measure adult normal femur specimen in order to obtain accurate femoral resection and match the distal femoral in total knee arthroplasty.[Method](1)Forty-seven adult normal femur specimens of central Chinese were used for taking digital pictures in both anteroposterior and medialateral position.Five angles were measured through drawing lines of fixed point.(2)The exact position of the entry point was defined by the two wires on the specimens.[Result](1)The five angles reflect distal femoral anatomy features on the frontal plane and sagittal plane.(2)The mean value of distance from the entry point to the center of the intercondylar notch was 6.21 mm and the distance from the entry point to the anterior margin of the femoral posterior cruciate ligament(PCL) insertion is found to be 6.7 mm.[Conclusion](1)The distal one-third of femora was found to be outward bowing on frontal plane and forward bowing on Sagittal plane.Especially,the forward bowing is more remarkable than Outward bowing.So,when the position of intramedullary guide stick is decided by distal femoral anatomy,the axis alignments on frontal and Sagittal planes are both important.(2)During total knee afthroplasty the exact position of entry point may be defined by the Center of the intefcondylar notch and femoral PCL insertion.

Objective To detect the expression of the tryptase in the plasma,and study the meaning in brain traumatic patients.Methods There were two groups:the brain traumatic group(40 patients)and the control group (20 health people).The content of plasma tryptase was determined by fluorescence enzyme immunoassay..Results The level of plasma tryptase had no statistical significance in control group(2.97 ±1.05)μg/L compared with the brain traumatic group(3.03 ±1.39)μg/L,however there had statistical significance comparing with sever brain traumatic patients(3.84 ±0.52μg/L)(t =3.32,P <0.05).4 cases of death in patients with severe head injury group content of tryptase (5.85 ±1.05)μg/L,which was significantly higher than the group of 16 cases of injury in severe head injury after 2 months still alive with the content of serum tryptase (2.49 ±0.52)μg/L,the difference was statistically significant (t =8.13,P <0.01).Conclusion The plasma tryptase level in sever brain traumatic patients increased significantly,and might be of importance for treatment strategies and prognosis.

Objective To compare the advantages and disadvantages of non-irrigation and irrigation in the surgical approach of chronic subdural hematoma (CSDH),thus to provide reference for clinical treatment of CSDH.Methods Clinical data of 102 patients with CSDH were retrospectively analyzed.According to the different operation methods,the patients were divided into the non-irrigation group(52 cases) and the irrigation group(50 cases).The blood loss during the procedure,operative time,length of stay and postoperative complication rate between the two groups were compared,and the causes of postoperative complications were analyzed.Results The blood loss during the procedure,operative time and length of stay in the non-irrigation group were (6.73 ± 1.17) mL,(15.06 ± 2.64) min and (10.74 ± 2.20) d,respectively,which in the irrigation group were (19.52 ± 3.18) mL,(38.54 ± 6.95) min and (10.44 ± 2.07)d,respectively,there were statistically significant differences between the two groups in the blood loss during the procedure and the operative time (t =-27.11,-22.72,all P ＜ 0.05),there was no statistically significant difference between the two groups in the length of stay (t =0.70,P ＞ 0.05).The incidence rates of postoperative complication in the non-irrigation group and irrigation group were 8.00％ and 7.69％,respectively,there was no significant difference between the two groups (x2 =0.003,P ＞ 0.05).Conclusion Each of the two methods has its own advantages and disadvantages in the treatment of CSDH.Compared with burr hole irrigation,burr hole non irrigation has the advantages of less blood loss and shorter operative time.However,burr hole non-irrigation is more likely to suffer serious complication.We should select suitable surgical approach by the specific circumstances of the patients.The causes of postoperative complications of CSDH are varied.In particular,there is an important relationship between the non-standard operation and postoperative complications.

Objective To compare the pathological changes of the kidney in two-kidney one-clip hypertension and spontaneous hypertension rats so as to provide some experimental basis for clinical prevention and treatment of primary and secondary hypertension. Methods Conventional histopathology and elastic staining methods were used to observe the morphological changes of kidney tissues and renal arterioles from two-kidney one-clip (2K1C) and spontaneously hypertensive rats (SHR) of different weeks of age. Results The blood pressure of 2K1C rats after 4 weeks of operation reached (187?24)mmHg,which was significantly higher than that of controls (P

Objective:To study the radiation-sensitizing effects of nimotuzumab and X-ray radiotherapy on human esophageal carcino-ma KYSE450 cells. Methods:Human esophageal carcinoma cells KYSE450 were treated with nimotuzumab, irradiation, and the combi-nation of both. Cell growth inhibition was evaluated by MTT assay, and cell cycle distribution and apoptosis were analyzed by flow cy-tometry assay. Cell radiosensitivity was tested by clonogenic assay, and the survival curve was fitted using multi-target single-hit mod-el. The combination and accelerated radiation groups were tested by microarray technology, and the differentially expressed genes were screened among the two groups. Results:The growth of KYSE450 cells was inhibited in three groups, namely, the group treated with nimotuzumab, the group treated with irradiation, and the group treated with both. The group treated with both nimotuzumab and irradiation resulted in the highest inhibition rate (35.25%±5.62%) compared with that of the nimotuzumab (16.12%±8.73%) and ir-radiation groups (27.64%± 6.66%) (F=10.953, P<0.001). The highest rates of G2 phase arrest and cell apoptosis were observed in the group treated with the combination of nimotuzumab (29.37%±7.29%) (F=17.299, P<0.001) and irradiation (18.80%±2.03%) (F=85.691, P<0.001). Multi-target single-hit model showed that the values of SF2, Do, and Dq in the group with both treatments were smaller than those of the irradiation group with sensitization enhancement ratio of 1.63, which confirmed the radiosensitization effect of ni-motuzumab on KYSE450 cells. Microarray technology analysis found that nimotuzumab can enhance the radiosensitivity of esophageal squamous cell carcinoma by cutting the genes of EGF/PDGF signaling pathways. Conclusion:This experiment shows that nimotuzumab can effectively inhibit the growth of human esophageal cancer cell KYSE450. Nimotuzumab can also promote apoptosis and G2 phase arrest when combined with X-ray radiotherapy, thereby enhancing the radiosensitivity of KYSE450 cells. This effect is associated with cutting the genes of EGFR signaling pathways.

Objective To understand the effect of health management to enhance the community hypertensive patients' self-efficacy. Method With the method of stratified random sampling, 347 patients who come from communities were diagnosed as hypertension were selected as research subjects from the range of Yingze in Taiyuan of Shanxi province. There were 191 males and 156 females, the age ranged from 38 to 72 (55.90±9.60) years. The self efficacy promotion plan was conducted on high blood pressure patients. A comparison before and after six months of health management was made among the self efficacy scores, daily life scores, health behavior scores, drug behavior scores, medical compliance behavior scores by using self-efficacy scale. Excel 2007 and SPSS 19.0 were used for data analyses. Result Before the implementation of health management, the self efficacy scores of research subjects were 26.96 ± 0.77. After the implementation of health management, the value increased to 29.51 ± 0.86 (t=-41.23, P<0.05). In four dimensions, daily life (before and after management 6.85 ± 0.20 and 7.49 ± 0.31, t=-40.66), drug behaviors (before and after management 7.52 ± 0.21 vs. 7.98 ± 0.23, t=-26.93) and medical compliance behavior scores (before and after management 5.26±0.15 vs. 6.78±0.19, t=-115.97) were higher than those before the health management except health behaviors (before and after management 7.25 ± 0.40 vs. 7.26 ± 0.40, t=-1.94, P<0.05). Conclusion Health management regulated the self care behavior of patients with hypertension, improved the patients' compliance and enhanced self efficacy, which played an important role in controlling the development of disease.
