OBJECTIVETo compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.

METHODSThirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.

RESULTSAfter treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).

CONCLUSIONEncircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.

Objective: To investigate the efficacy and toxic reaction of the accelerated hyperfraction radiotherapy for esophageal carcinoma. Methods: Eighty patients with esophageal carcinoma were randomized into the conventional fraction group (CF,40 cases) and the accelerated hyperfraction group (AHF,40 cases) from January 1994 to May 1995. CF group received a fraction dose of 2 Gy once a day, 5 times a week and to a total dose of 70 Gy. AHF group received the same dose as the CF group during the first two thirds of the therapeutic course(40 Gy),then followed by a fraction dose of 1.5 Gy one time twice a day, with an interval of more than 6 hours, and to a total dose of 30 Gy. The total dose of 2 stages was 70 Gy. The same 10 mV linear accelerator X ray radiotherapy was used in both groups. Results: The 3 year actual survival and tumor local control rates in the group AHF were significantly improved compared with group CF, being 42.5% vs 25% and 52.5% vs 25% respectively. There were no significant differences in radiation reactions and complications between 2 groups. The radiation treatment could be completed without any break. Conclusion: The accelerated hyperfraction radiotherapy can improve the tumor local control and survival rates in esophageal carcinoma. The radiation reactions and complications with the AHF radiotherapy are not significantly greater than with the CF radiotherapy. The patients can tolerate the AHF radiotherapy. [

Objective To overcome the fact that SRV-NM virus can only multiple and amplify through partially pu-rified jaagsiekte retrovirus inoculated intratracheally in sheep but it cannot be augmented using in vitro cell culture, we con-structed JSRV-NM pseudovirions based on high efficiency packing system of lentivirus. Methods Lentivirus of three high efficiency packing plasmids system pMD.G, pCMV-HIV 8.2 and pHIV-eGFP was developed, and JSRV-NM-env coated plasmid pCMVJSRV-NM was used to substitute VSV-G virus coated plasmid pMD.G then co-transfected into 293T cells to replicate, package and produce restructured JSRV-NM pseudovirions. Gene expression of pseudovirion was determined through WPRE using real time PCR; Virus infectivity was detected through inoculating JSRV-NM pseudovirions into 24 pore plates. Results We construct JSRV-NM pseudovirions successfully based on the lentivirus system. JSRV-NM pseudo-virions can also be concentrated to higher titer (108 TU/mL detected by real time PCR by ultracentrifugation without signifi-cant loss of activity. JSRV-NM and VSV-G pseudovirions infected on Hela cells (both MOI= 3) respectively and no obvi-ous difference were shown on their infection efficiency detected by real time PCR. Conclusion Based on lentivirus system, JSRV-NM pseudovirions can be multipled and amplified in 293T cell culture in vitro. JSRV-NM pseudovirions is stable without loss its infection activity and the requirements of biological laboratory safety II was also met. JSRV-NM pseudoviri-ons will provide a useful tool for further study of JSRV-NM-env infection across species or its induction of lung adenocarci-noma.

ObjectiveTo assess the relationship of filaggrin expression with atopic diathesis and disease severity in patients with alopecia areata (AA).MethodsThirty-seven patients with AA aged (26.3 ± 10.6) years were enrolled in this study.Atopic diseases were noted in 8 of these patients.Clinical data and laboratory test resuhs were reviewed.Immunohistochemical staining was performed to quantify the expression of filaggrin protein in scalp biopsy specimens from all of the 37 patients with AA and from 10 human controls,and fluorescence-based semiquantitative reverse transcription-PCR to detect the expression of filaggrin mRNA in scalp biopsy specimens from 22 patients with AA and 13 healthy controls.Data were statistically analyzed by Mann Whitney U test,chi-square test,and Spearman's rank correlation test.ResultsThe expressions of filaggrin protein and mRNA were significantly lower in patients with AA than in the controls(P ＜ 0.05 or 0.01 ),and the decrease seemed more obvious in patients with large areas of lesions,long duration of disease,and nail abnormalities,but the degree of decrease was unrelated to the complication with atopic diseases.No significant differences were observed in sex ratio,age at onset,disease duration,area of hair loss,the prevalence of family history or incidence of nail abnormalities and increase in serum IgE and eosinophils,between patients with atopic diseases and those without.ConclusionsThe expressions of filaggrin protein and mRNA are decreased in patients with AA,suggesting that filaggrin may participate in the development of AA and is correlated with the severity of AA.

Objective To evaluate the myocardial protective effect of dexmedetomidine in the pediatric patients undergoing total correction of tetralogy of Fallot.Methods Forty ASA physical status Ⅱ] or Ⅲ pediatric patients of both sexes,aged 9 months-5 yr,weighing 7-21 kg,scheduled for elective total correction of tetralogy of Fallot under cardiopulmonary bypass,were randomly divided into 2 groups (n =20 each):control group (C group) and dexmedetomidine group (D group).Anesthesia was induced with iv injection of midazolam,sufentanil,etomidate and rocuronium.The patients were endotracheally intubated and mechanically ventilated.After intubation,dexmedetomidine was infused intravenously at 0.6 μg· kg-1 · h-1 until the end of operation in group D,while the equal volume normal saline was given instead of dexmedetomidine in group C.Venous blood samples were obtained before operation,at the end of operation and at 24 h after operation for determination of plasma TNF-α and IL-6 concentrations.The occurence of anoxic spells was recorded.Results The concentrations of plasma TNF-α and IL-6 were significantly lower at the end of operation and 24 h after operation in group D than in group C(P ＜0.05).The incidence of anoxic spells was 0 in group D,however it was 20％ in group C.Conclusion For the pediatric patients undergoing total correction of tetralogy of Fallot under cardiopulmonary bypass,dexmedetomidine infused at 0.6 μg· kg-1 · h-1 during operation can exert myocardial protective effect with clinical significance.

Objective To investigate the effect of mesenchymal stem cells (MSCs) on subcutaneous xenograft tumors in mice with Lewis lung cancer. Methods MSCs isolated from bone marrow of C57BL/6 mice were made into single cell suspension and were cultured in vitro. The cells of the 4th to 5th passage were used for the subsequent experiments. Fifty six C57BL/6 mice were inoculated subcutaneously with Lewis lung cancer cells, and were grouped into Group D0 (MSCs were given simultaneously with inoculation)and Group D10(MSCs were given 10 d after inoculation). Group D0 included three subgroups (n=8): Group 1 with inoculation of tumor cells, Group 2 with inoculation of tumor cells and MSCs, and Group 3 with inoculation of tumor cells and tail intravenous injection of MSCs. Group D10 included four groups: Group 4 with inoculation of tumor cells and injection of MSCs in tumors, Group 5 with equivalent PBS (the control of Group 4), Group 6 with inoculation of tumor cells and tail intravenous injection of MSCs, and Group 7 with equivalent PBS (the control of Group 6). The time of tumor formation and the volume of tumor were observed and compared among the groups. ResultsIn Group D0, earlier onset of tumor development was observed in Group 2 as compared to Group 1 and Group 3 (P<0.05), while there was no significant difference on the volume of tumor in the three groups (P>0.05). In Group D10, the volume of tumors were larger in Group 4 compared to the control (P<0.05), while there was no significant difference on the volume of tumors between Group 6 and the control (P>0.05). Conclusion Inoculating mixture of MSCs and Lewis lung cancer cells accelerates tumor formation,and injection of MSCs in tumors stimulates the growth of tumors.

Objective To evaluate the effectiveness and safety of open tension-free hernioplasty and two kind of laparoscopic hernia repair for the treatment of primary unilateral inguinal hernia. Methods Patients suffering from primary unilateral inguinal hernia were randomly divided into 3 groups to undergoopen operation with mesh-plug and patch or transabdominal preperitoneal hernioplasty (TAPP) or totally extraperitoneal hernioplasty (ZEP). Results From February 2006 to February 2009, a total of 164patients were divided into 3 groups, with 62 undergoing open tension-free mesh-plug hernia repair, 50receiving TAPP and 52 receiving TEP. Postoperative patients were then followed up for a period of(16±8)months. The average operating time for the patients in the open mesh repair group was significantly shorter compared to the other two groups (P＜0.01 ). The cost in the open mesh repair group was also significantly lower than the other two groups (P＜0.01). The pain scores in open mesh group were significantly higher than those in the other two groups (P＜0.01). The hospital stay and the recovery time were both significantly longer in the open mesh repair group (P＜0.01) compared to the other two groups. No major complications and recurrence was found in neither groups. Conclusions Open tension-free mesh-plug hernia repair, TAPP and TEP are all safe and effective for the treatment for patients with primary unilateral inguinal hernia. TAPP and TEP are superior to open tension-free mesh-plug hernia repair as these two procedures involve less postoperative pain and fast recovery.
