OBJECTIVE: To observe the clinical efficacy of nasal vestibule eczema by using beclomethasone dipropionate in combination with He-Ne laser therapy. METHOD: The 200 cases of nasal vestibule eczema patients were randomly divided into treatment and control groups. The control group received the rub beclomethasone dipropionate cream treatment one time per day. The treatment group supplemented with He-Ne laser irradiation treatment on the basis of the control group on the same treatment, alsoone time per day. Then the results were analyzed. RESULT: The total effective rate was 100.0% in treatment group, while 75.0% in the control group. The difference between the two groups was statistically significant (P < 0.05). CONCLUSION Beclomethasone dipropionate cream combined with He-Ne laser irradiation therapy on nasal vestibule eczema is significant, and easily to operate, with significant anti-inflammatory, anti-itch, analgesic effects.

Objective To study the treatment of intra-abdominal hypertension syndrome (IAHS) secondary to fulminant acute pancreatitis(FAP). MethodsWe retrospectively analyse therapeutic results of 14 IAHS cases secondary to FAP during the period of 1998～2003. ResultsFour out of the 6 cases receiving nonoperative therapy died with motality rate of 67.7% (4/6). Two out of the 8 cases treated by early surgery died. The motality rate was 25% (2/8), which was significantly different from that treated conservatively . ConclusionModerate to severe IAHS cases secondary to fulminant acute pancreatitis should undergo exploration in the early phase of disease to improve the prognosis of FAP.

Objective To investigate the relationship between NF-kB activity of pancreatic acinar cells(PAC) and blood inflammatory cytokines ( IL-2, IL-6, IL-10, TNF-? and ICAM-1) in rat's ANP. Methods Fourty rats were randomly divided into two groups: ANP model group and contrast group. ANP was induced by retrograde injection of 5% sodium taurocholate into the pancreatic duct. NF-KB activity in the cell nuclear and IkBa activity in the cell spasm of PAC were measured by EMSA and Western-blot. Inflammatory cytokines were measured by ELISA. Results ANP model's NF-KB activity increased [(31.4?5.7) ?mol/L vs. (8.3?2.4) ?mol/L.(39. 4 ? 6. 4) ?mol/L vs. (10.7 ?2.6) ?mol/L.

Objective:To explore the significance of the clinical target volume (CTV) dose optimization in the upper and middle neck in protecting the laryngopharynx, anterior and posterior rings during intensity-modulated radiotherapy (IMRT) and multimodal imaging system for nasopharyngeal carcinoma.Methods:Clinical data of 298 nasopharyngeal carcinoma patients admitted to Jiangsu Cancer Hospital from 2016 to 2018 were retrospectively analyzed. According to the following five strategies of CTV dose optimization in the upper and middle neck: group A, complete optimization of bilateral cervical lymph nodes (CLNs), that is, the CTV doses of bilateral CLNs were 50.4 Gy; group B, complete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the contralateral CLNs was 60 Gy; group C, incomplete optimization of bilateral CLNs, that is, the CTV doses of bilateral CLNs were 50.4 Gy, while the suspicious positive CLNs were selectively boosted to 60 Gy; group D, incomplete optimization of unilateral CLNs, that is, the CTV dose of unilateral CLNs was 50.4 Gy and the suspicious positive CLNs were selectively boosted to 60 Gy, and the CTV dose of contralateral side was 60 Gy; group E: no optimization, that is, the CTV doses of bilateral CLNs were 60 Gy.Results:Among 298 patients, 215 patients received dose optimization and 83 cases did not receive dose optimization. In the dose optimization schemes, 114 cases were assigned in group A, 36 cases in group B, 60 cases in group C and 5 cases in group D. The median (range) follow-up time was 28.5(6.0-46.3) months. The overall survival rate was 95.6%, the progression-free survival rate was 84.2% and the locoregional control rate of CLNs was 98.0%. Local relapse of CLNs occurred in six patients, including 1 case of retropharyngeal lymph node, 4 cases of Ⅱ area and 1 case of Ⅳ area. The P values of average dose of laryngopharynx in group A, group B, group C and group D compared with that in group E were<0.001, 0.016, 0.001 and 0.572, respectively. The P values of the average dose of the anterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.011, <0.001 and 0.805, respectively. The P values of the average dose of the posterior ring in group A, group B, group C and group D compared with that in group E were<0.001, 0.004, <0.001 and 0.252, respectively.Conclusions:Combined with the metastatic rules of CLNs and multimodal imaging system, it is safe to optimize the CTV dose of the upper and middle neck during IMRT in nasopharyngeal carcinoma patients, which can significantly reduce the doses of laryngopharynx, anterior and posterior rings, thereby providing evidence for reducing the CTV dose in the upper and middle neck.

Quantitative RT(reverse transcriptase) assay was established to detect the reverse transcriptase in plasma of thirty-four Chinese Banna minipig inbred in this work. The protocol was given in the RT kit (Roche), using HIV-1 as the positive control of the kit and supernatant of PK-15 as the PERV positive control respectively. The results show that positive reverse transcriptase reaction can be detected in the plasma of the pigs, but the levels are much lower than that of HIV-1 and lower than that of PERV in supernatant of PK-15.

OBJECTIVE: To evaluate the surgical outcomes of laparoscopic splenectomy and to investigate the learning curve of laparoscopic splenectomy. METHODS: Forty cases of laparoscopic splenectomy (performed by W.Y. between September 2008 and August 2010) in our general surgery department were reviewed, and the cases were divided equally into 4 groups (group I, II, III, IV) according the time sequence of the operations. The operating time, blood loss, conversion to open surgery, conversion to hand-assisted laparoscopic splenectomy, postoperative hospital stay, postoperative liquid diet recovery time, intra- and postoperative complications and the operative frequency were compared. RESULTS: There were no statistical differences among the groups in age and gender (P>0.05). The operating time, blood loss and postoperative hospital stay of groups III and IV were significantly less than those of groups I and II (P<0 .05). Postoperative liquid diet recovery time appear to show a gradual shortening trend from Group I to Group IV, but the differences were not at standard statistical thresholds (P>0.05). Frequency of conversion to open surgery, of conversion to hand-assisted laparoscopic splenectomy, of complications among the four groups were also not statistically different (P>0.05). The operative frequency of group I-IV increased from 1.25/month to 2.5/month. CONCLUSION The learning curve of laparoscopic splenectomy for surgeon who was experienced in open splenectomy and laparoscope cholecystectomy is approximately 20 cases, and the operative frequency is about 1.33/month.

Mesenchymal stem cells from bone marrow of Rhesus monkey (RhBMSCs) were isolated by density gradient centrifugation, purified by adherence separation, and further identified by phenotype and karyotype analysis. Growth characteristics of RhBMSCs were investigated by observation of cell proliferation and detection of apoptosis. Density gradient centrifugation and adherence separation revealed a simple method to obtain fairly pure RhBMSCs. Fusiform was the most common form of cell under observation, and cell karyotype was normal. Phenotyping assay revealed that the RhBMSCs are highly positive (99.2%) for CD29 when compared with the low positive rates (less than 3.2%) for CD34, CD45 and HLA-DR, which indicated a successful isolation of high purity RhBMSCs and a vigorous activity of cells to proliferate. But the proliferation activity of RhBMSCs gradually decreased following the increasing of cell generations. The methods and results of isolation, expansion, identification and growth characteristics of RhBMSCs were discussed in this paper, which may be helpful to understanding the bone marrow mesenchymal stem cells of human, and may serve as the groundwork for orientated differentiation of RhBMSCs and tissue repairment on experimental animal model of rhesus monkey.
