Objective To investigate the effect of Dexamethasone on microtubule - associated protein 1 light chain 3(LC3)expression of cells and neurons in cerebral cortex of juvenile Wistar rats with sepsis. Methods Models of juvenile Wistar rats with sepsis were established through cecal ligation and puncture(CLP). Totally 60 cases of 30 -day - old juvenile male Wistar rats were randomly divided into sham - operation group(10 cases),non - treated group (25 cases)and Dexamethasone group(25 cases). Twelve hours after CLP,rats in Dexamethasone group were injected with Dexamethasone(1 mg / kg)via tail vein every other day,with a total of 3 times. The same dose of saline was used in the non - treated group. All rats were killed at the age of 40 days. Expressions of LC3 and neuronal nuclei(NeuN)of cells in cerebral cortex of rats were detected by using immunofluorescence assay,and the number of positive cells was calculated by using image analysis system software. Expressions of LC3 - Ⅰ and LC3 - Ⅱ protein were measured by a-dopting Western blot. Results Three hours after CLP,rats appeared to be curled up and showed piloerection and shi-vering and the neurobehavioral score in non - treated group was significantly lower than that in sham - operation group (t = 9. 895,P = 0. 000). Twelve of 25 rats in Dexamethasone group died in 10 days after CLP(48% ),while 8 of 25 rats in non - treated group died(32% ),and the difference was not statistically significant between the 2 groups(χ2 =1. 333,P = 0. 248). The immunofluorescence staining and image analysis showed the percentage of LC3 positive cells in non - treated group was significantly increased(0. 606 7 ± 0. 030 1 vs 0. 353 3 ± 0. 025 8,t = 15. 644,P = 0. 000;0. 606 7 ± 0. 030 1 vs 0. 270 3 ± 0. 019 4,t = 22. 450,P = 0. 000). In non - treated group,the LC3 expression of cells in the cerebral cortex of rats was up - regulated,and the LC3 - Ⅱ/ LC3 - Ⅰ ratio was significantly higher than that in sham operation group and Dexamethasone group(0. 413 3 ± 0. 022 5 vs 0. 205 0 ± 0. 015 2,t = 18. 802,P = 0. 000;0. 413 3 ± 0. 022 5 vs 0. 185 0 ± 0. 023 5,t = 17. 206,P = 0. 000). The LC3 positive neurons in the cerebral cortex of rats were less in sham operation group and Dexamethasone group. The LC3 positive neurons were more in non - treated group than that in sham operation group and Dexamethasone group(0. 580 0 ± 0. 020 0 vs 0. 298 3 ± 0. 014 7,t =27. 783;P = 0. 000;0. 580 0 ± 0. 020 0 vs 0. 261 7 ± 0. 017 2,t = 28. 614;P = 0. 000). Conclusions The LC3 expres-sion of cells in the cerebral cortex of juvenile Wistar rats with sepsis was up - regulated,LC3 - Ⅱ/ LC3 - Ⅰ ratio in-creased,and the number of LC3 positive neurons also increased,while Dexamethasone could have inhibitory effect on them.

Objective To evaluate if Ⅵ region lymph nodes metastasis status can be a reliable indicator in prediction of lateral lymph nodes metastasis in papillary thyroid carcinoma (PTC) with negative cervical lymph nodes (cN0).Methods Retrospectively reviewed the medical records from January 2003 to October 2011 of 73 patients with PTC who underwent prophylactic lateral neck dissection (Ⅱ-Ⅴ region or Ⅱ-Ⅳ region).The relationship between cervical lymph nodes metastasis and lateral lymph nodes metastasis was assessed.Results The rate of lateral lymph nodes metastasis was 16.4％(12/73).The rate of Ⅵ region lymph nodes metastasis was 42.5％(31/73).Multivariate analysis showed that Ⅵ region lymph nodes metastasis was the risk factor of lateral lymph nodes metastasis in cN0 patients with PTC(OR =7.3,P=0.020).Conclusion Ⅵ region lymph nodes metastasis status can be a reliable indicator of lateral lymph nodes metastasis in cN0 patients with PTC.

Objective To evaluate the pattern of lateral cervical metastases and to investigate the risk factors for lateral cervical lymph node metastases in paoiuary thyroid carcinoma patients with clinical negative lateral neck lymph node.Methods 73 patients with paoiuary thyroid carcinoma who underwent prophylactic lateral neck dissections(level Ⅱ-Ⅵ or level Ⅱ-ⅣandⅥ) were reviewed retrospectively on their medical records paoiuary thyroid carcinoma.None of patients in this study had a clinically positive lymph node.Neck dissection specimens were obtained for histological analysis for node metastasis with respect to the individual neck levels.Results Occult metastases in lateral neck were observed in 12(16.4 ％)patients.9.6 ％,0,13.6 ％,9.6 ％,0,4.8 ％ and 42.4 ％ patients had histologically positive lymph nodes in levels Ⅱa,Ⅱb,Ⅲ,Ⅳ,Va,Vband Ⅵ respectively.In multivariate analysis,lymphatic metastases in level Ⅵ was associated with lateral neck metastasis(OR=7.3,P=0.020)in cN0 patients with paoiuary thyroid carcinoma.Conclusion Levels Ⅲ,Ⅱa and Ⅳwere the most common stages showing occult lymph node metastases.Prophylactic lateral neck dissections may be omitted in the treatment of cN0 PTC patients ff level Ⅵ lymphatic metastases are not found on histological exam.

Objective To compare the treatment outcome of underwent surgery plus radiotherapy and radiotherapy/chemoradiotherapy plus salvage surgery for stage Ⅲ/Ⅳ laryngeal carcinoma,to investigate an optimized treatment for the patients of stage Ⅲ/Ⅳ laryngeal carcinoma.Methods Clinical data from 103 patients with stage Ⅲ (39 cases) or stage Ⅳ (64 cases) laryngeal carcinoma were retrospectively analyzed.The patients were divided into surgery plus radiotherapy group (S±R,46 cases) and radiotherapy/chemoradiotherapy plus salvage surgery group (R±S,57 cases).Overall survival,relapse free survival,and laryngeal preservation rate were used to compare the treatment outcome between two groups.Multivariate regression models were used to analyze the independent factors for survival and laryngeal preservation rate.Results Survival rate was higher in S±R group than in R±S group [2 year overall survival/relapse free survival 74.7 ％ (34/46) / 72.4 ％ (33/46) vs 46.4 ％ (26/57) / 40.9 ％ (23/57),P ＜ 0.05].Laryngeal preservation rate was higher in R±S group than in S±R group [93.0 ％ (15/46) vs 32.6 ％ (53/57),P ＜ 0.05].Multivariate analysis demonstrated that treatment modality and T stage were independent factors for long-term survival,while treatment modality was the only an independent factor for laryngeal preservation rate.Conclusions Surgery plus radiotherapy result in better survival and lower laryngeal preservation rate than radiotherapy/chemoradiotherapy plus salvage surgery in treatment of stage Ⅲ/Ⅳ laryngeal carcinoma.Surgery plus radiotherapy should be the first choice for treatment of locally advanced laryngeal carcinoma.Improvement of the quality of life could be achieved by laryngeal preservation surgery and phonation reconstruction procedures.

Objective To study the values of neck dissection for thyroid carcinoma who received nonstandard operation and help to choose good re-operation methods. Methods Retrospective investigation was carried out in 38 cases of neck dissection for thyroid carcinoma patients who received nonstandard operation during 1997 to 2005, and 32 cases were treated with neck dissection. Results Pathological results confirmed there were 73.68 % with residual tumor, positive rate of thyroid was 47.38 %, and that cervical lymph node was 57.89 %. Conclusion The residual rate of cervical lymph nodes of reoperated patients with thyroid carcinoma was relatively higher, so neck dissection for thyroid carcinoma who received nonstandard operation was necessary.

Objective To investigate the distribution and genetic characteristic of etiological agents among children with hand,foot and mouth disease(HFMD)in Shanghai and neighbor areas in 2008.Methods Throat swabs were collected from the inpatients with HFMD from May to June 2008 in Pediatrics Hospital affiliated to Fudan University,Shanghai,and Deqing,Zhejiang Province.Cerebral spinal fluid(CSF)from some patients were collected as well.Vero,MRC-5 and RD ceils were used to isolate the possible pathogens by observing cytopathic effect(CPE).Enterovirus genus,Coxsaekie virus group A type 16(CoxA16)and enterovirus type 71(EV71)were detected by reverse transcriptase-polymerase chain reaction(RT-PCR),and finally identified by sequencing.Results A total of 107 swabs and 22 CSF samples were collected from all 100 inpatients.Swabs of 50 children caused CPE observed.Among them,enteroviruses accounted for 74.0%(37/50),which including 26 (52.0%)of EV71,10(20%)of CoxAl6 and 1(2.0%)of CoxB3,and 13(26.0%)of other pathogens.All the 26 EV71 strains were similar with the isolates from Zhejiang Province and Fuyang,Anhui Province in 2008,which belonged tO genotype Cl all the 10 CoxAl6 strains belonged to genetic lineages C.Conclusions The causative agents of HFMD are complicated.CoxA16 and EV71 are predominant among children with HFMD in Shanghai and neighbor areas in 2008,while the pathogens of some patients are still unknown.

Objective To report the clinical results and the advantages/disadvantages of anterolateral thigh flap (ALT) and forearm flap (FAF) in reconstruction of head and neck defect after cancer ablation. Methods 20 FAFs and 12 ALTs were performed to repair the head and neck tumor ablation defects. Of the 20 FAFs, 7 were used for repair of the through and through buccal defects, 4 for circumferential bypopharyngeal defects, 2 for plate defects, 1 for parotid area skin defect, 4 for floor of the mouth defects, and 2 for defect, of the base of the tongue, while of the 12 ALTs, 3 were used for repair of the defects of the base of the tongue, 4 for plate defects, and 5 for the floor of the mouth and/or lower gum defects. Survival of the flaps, function of the recipient site, and impact to the donor site were compared between these two groups to analyze the advantages/disadvantsges and key technique details of these two flaps. Results 19 FAFs totally survived. Vascular crisis occurred in 2 cases of FAF, of which 1 flap survived after conservative treatment, while the other 1 developed partial necrosis. All the 12 ALTs survived, without vascular crisis. 2 of the 14 planed ALTs were abandoned and replaced by FAFs, of which 1 because of absence of the perforating branch and the other 1 because of injury of the perforating branch. Secondary defects of the ALTs could be closed primarily, while secondary defects of the FAFs should be closed with skin grafts. Conlusion Both ALT and FAF can be performed with high survival rate. Each has its own advantages. Selection of the donor site deponds on situation of the defect and purpose of the reconstruction.
