Eyelid reconstruction is complex and challenging since it is not only for structural and functional restoration, but also for an acceptable aesthetic result. In full thickness eyelid injuries, it will involve both anterior and posterior lamella. Therefore, when reconstructing the defect, it requires at least two layers; one will be a flap with blood supply, and the other can be a free graft. In this case, a rotational advancement cheek flap and composite graft were used to reconstruct the lower eyelid.

ObjectiveTo evaluate the effect of auscultation, partial pressure of carbon dioxide in end-expiration (PETCO2), transillumination technique to judge whether the endotracheal tube is misplaced into the esophagus. Methods A blinded randomized controlled trial was conducted. Sixty patients with American Society of Anesthesiology (ASA) gradeⅠ-Ⅱundergoing endotracheal intubation in Fengxian Central Hospital admitted from September 2014 to February 2015 were enrolled. Two endotracheal tubes with the same size were respectively inserted into the trachea and esophagus for the same depth after general anesthesia by the same person. Two blinded anesthetists with different experience checked the tube position using three methods including auscultation, PETCO2, and transillumination technique, respectively. The order of the tubes tested (trachea or esophagus) and the method used were randomized according to randomise numbers table. The experienced anesthetists conducted the test first, followed by an inexperienced anesthetist conducting the same methods. The numbers of right and wrong determinations with different methods by different anesthetists were recorded.Results Sixty patients underwent the procedures for 180 times, with intratracheal intubation for 90 times, and esophageal intubation for 90 times. It was shown that the results were not different in two groups [96.7% (174/180) vs. 92.2% (166/180),χ2 = 3.500,P = 0.057]. By using auscultation, the correct rate of experienced anesthetist was higher than that of inexperienced (95.0% vs. 78.3%,χ2 = 5.786,P = 0.013). Using PETCO2, both anesthetists were correct in all cases, and the accuracy was 100%. Using transillumination, the experienced anesthetist was mistaken in 3 cases (accuracy was 95.0%), while the inexperienced mistook in 1 case (accuracy was 98.3%), and no significant difference was found between two groups (χ2 = 0.500,P = 0.250). The correct rate of using transilluminaion was significantly higher than that of using auscultation (χ2 = 7.563,P = 0.004). The sensitivity and specificity of the auscultation was 70.0% and 80.0%, that of transillumination technique was 96.7% and 93.3%,and PETCO2 was 100%, respectively, for two groups.ConclusionsPETCO2 is the most reliable method for determining tube position, and it is superior to auscultation and transilluminaion. Transillumintaion technique is superior to auscultation, irrespective of anesthetists' experience, while the accuracy of auscultation showed an obvious relationship with the anesthetists' experience.

OBJECTIVE: To investigate the curative effects of nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel on burn residual wounds.METHODS: Forty burn patients with residual wounds because of deep second degree burn and full-thickness burn, were randomly divided into control group and management group. There were 20 patients in both groups. The patients of management group were treated by nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel. The patients of control group were treated by saline and paraffin absorbent gauze. Healing time, wound healing rates at different time points,cases of infected wound and results of bacterial culture before and 7 days following treatment, and drug adverse reaction were recorded.RESULTS: The healing time of management group was significantly shorter than the control group (P < 0.01). The wound healing rates of management group was significantly higher than the control group at different time points (P< 0.01). The cases of infected wound was significantly fewer than the control group after treating (P < 0.01). The pathogenic bacteria detection rate was significantly lower than the control group after 7 days (P < 0.01).CONCLUSION: There was better antibacterial activity, decurtating the healing time when the management of nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel on burn residual wounds were put into practice.

Objective To study the diagnostic value of combined detection of serum CEA,CA199,CA125,AFP and fecal occult blood(FOB) in Dukes B stage colon carcinoma.Methods The above indicators in 56 patients with colon carcinoma (colon carcinoma group),35 patients with colonic polyp benign disease and 41 healthy individuals undergoing physical examination were measured.Then the sensitivity,and specificity of single index detection and their combined detection were analyzed.Results The levels and positive rates of CEA,CA199,CA125 and FOB in the colon cancer group were significantly higher than those in the colonic polyp group and healthy control group (P＜0.05),but the AFP level and positive rate had no statistical difference compared with the colonic polyp group.Serum CEA,CA125,CA199 and FOB were selected into the Logistic regression equation.The corresponding areas under the curve (AUC) were 0.745,0.886,0.792 and 0.864 respectively;the positive detection rates were 48.2 ％,35.7 ％,39.3 ％ and 78.6 ％ respectively.The combined detection could increased the specificity,sensitivity and AUC to 87.5 ％,92.1％ and 0.957,which were more superior to that in the single index detection.Conclusion The combined detection of serum CEA,CA199,CA 125 and FOB can provide the powerful basis for early diagnosing colonic cancer.

OBJECTIVETo retrospective analysis the complications after treatment of metacarpal and phalangeal fractures with internal fixation, and propose measures to prevent or reduce surgical complications.

METHODSFrom July 2007 to October 2009, 342 patients with metacarpal and phalangeal fractures were treated with internal fixation,including 203 males and 139 females with an average age of 30.4 years old ranging from 18 to 56 years. There were 217 right hands and 125 left hands, 38 cases of the first metacarpal fracture, 47 cases of the second metacarpal fracture, 52 cases of the third metacarpal fracture, 40 cases of the forth metacarpal fracture, 39 cases of the fifth metacarpal fracture, 43 cases of the proximal phalangeal fractures, 52 cases of the middle phalangeal fractures, and 48 case of the distal phalangeal fractures. The fractures were fixed with K-wires in 129 patients, mini plates in 153 cases, screws in 48 cases, wires in 12 cases.

RESULTSAll 324 patients were followed up for 3 to 15 months (averaged 8.5 months) and complications occurred in 74 patients (22.84%). The main complication was unhealthy wound healing in 24 patients (7.4%), others was adhesion of tendon in 54 patients (16.67%), malunion in 34 patients (10.49%), nonunion in 13 patients (4.01%) and shortening of metacarpal and phalangeal in 21 patients (7.41%).

CONCLUSIONThe important reasons responsible for complications are iatrogenic factors such as unsuitable implant selection, unskillful surgical technique and improper post-operative functional rehabilitation.

OBJECTIVETo explore the relationships between the expression of transgelin in dendritic cells (DCs) pulsed with hepatocellular carcinoma lysates and the functions of the DCs.

METHODSDCs derived from healthy human white blood cells were divided into 3 groups: one was pulsed with high metastatic potential hepatocellular carcinoma cell line (MHCC97H) lysates, one with lysates of a low metastatic potential cell line (MHCC97L), and one un-pulsed DCs served as the control. The morphology of the DCs was observed by confocal microscopy and scanning electron microscopy. The phenotypes of the DCs were detected by flowcytometric analysis. The mixed leucocyte reaction (MLR) test and IL-12 secretion of DCs in the supernatants of MLR were employed to determine the functions of the DCs; the expression of transgelin was detected by Western blot.

RESULTSThere were no morphological changes in the different DCs, but the levels of HLA-DR, CD80, CD83, CD86, MLR and IL-12 and transgelin were significantly higher in the two pulsed groups than those in the control group (P less than 0.01). In MHCC97H pulsed DCs, their CD80, CD83, CD86, and the expression of transgelin were also higher than those in the control group (P less than 0.05). The expression of transgelin was significantly higher in the MHCC97H pulsed group than in the MHCC97L loaded group, but CD80, CD83, CD86 and the level of IL-12 were all lower in the MHCC97H loaded DC group in comparison with those in the MHCC97 pulsed group (P less than 0.05).

CONCLUSIONThe expression of transgelin in DCs pulsed with HCC lysates is related to the functions of the DCs.

Objective To investigate the status of infection and distribution of rabies virus (RV) in different epidemic areas in China. Methods Brain specimens from animals and suspected patients were collected at the districts of high-, medium- and low incidence rates of human rabies and detected by both direct Immunofluorescence assay (DFA) and RT-PCR. Results 254 of 3007 specimens of dog brains showed RV positive by DFA (positive rate of 8.4% ). Among these 254 samples, 78 showed positive (positive rate of 30.7% ) by RT-PCR. 93 specimens from dogs and cats that had attacked human beings, 63 of them showed positive by DFA (positive rate of 67.7%) and all of them were also positive by RT-PCR. In addition, RV could also be detected in Apodemus agrarius,ferret badger, and suspected patients specimens from the districts under survey. There was no statistical difference between the infection rates of RV in different provinces and regions with different incidence of rabies. Conclusion There might be a relatively high infection rate of RV among the domestic dogs/cats in the endemic areas in China. Wild animals might have been infected with RV in the districts under survey.

OBJECTIVETo compare the difference of effects on SiO(2)-induced alveolitis and early fibrosis between bone marrow-derived mesenchymal-like stem cells (BM-MSCs) and BM-MSCs transfected by pcDNA3.1-HGF and to explore the mechanism of this effects.

METHODSThe Primary BM-MSCs from Wistar male young rats were cultured and labeled by 4, 6-diamidino-2-phenylindole (DAPI). Fifty Wistar rats were randomly divided into 3 groups:model group (10 rats),which was administered with SiO(2) by the trache, the next day,injected PBS via the tail vein; BM-MSCs group (20 rats),which was administered with SiO(2) by the trache, the next day,injected with 1 ml suspension of BM-MSCs via the tail vein; pcDNA3.1-HGF plus BM-MSC group (20 rats),which was administered with SiO(2) by the trache, the next day,injected with 1 ml suspension of BM-MSCs transfected by pcDNA3.1-HGF via the tail vein. On the 14th and 28th days after treatment, half of the animals were sacrificed, respectively, and the lungs were harvested for frozen section to observe the cell marked by DAPI. HE staining under a fluorescent microscope, and to observe the pulmonary alveolitis and fibrosis by HE and Masson staining under a light microscope. Western blot assay was used to detect the expression of HGF in rat lungs. The expression levels of tumor necrosis factor-α (TNF-α) in pulmonary tissues were analyzed quantitatively by ELISA. The contents of HYP in pulmonary tissues were analyzed quantitatively by sample hydrolysis method.

RESULTSOn the 14th and 28th days after treatment, the scores of pulmonary alveolitis and early fibrosis in pcDNA3.1-HGF plus BM-MSCs group were 2.36 ± 0.17, 2.8 ± 0.14 and 0.1 ± 0.11, 1.16 ± 0.13, which were significantly lower than those (1.68 ± 0.17, 1.58 ± 0.31 and 0.54 ± 0.15, 1.36 ± 0.13) in BM-MSCs group, also which were significantly lower those (2.36 ± 0.17, 2.80 ± 0.14 and 0.64 ± 0.09, 1.84 ± 0.17) in model group (P < 0.05); On the 14th and 28th days after treatment, the TNF-α contents of pulmonary tissues in pcDNA3.1-HGF plus BM-MSCs group were 280.4 ± 23.11 and 249.78 ± 22.33 pg/mg, which were significantly lower than those (341.58 ± 35.34, 442.29 ± 36.76 pg/mg and 319.51 ± 17.84, 348.53 ± 33.95 pg/mg) in BM-MSCs and model groups (P < 0.05); On the 14th and 28th days after treatment, the HYP contents of pulmonary tissues in pcDNA3.1-HGF plus BM-MSCs group were 0.46 ± 0.04 and 0.65 ± 0.05 µg/mg, which were significantly lower than those (0.63 ± 0.04, 1.04 ± 0.07 µg/mg and 0.72 ± 0.60, 1.39 ± 0.60 µg/mg) in BM-MSCs and model groups (P < 0.05).

CONCLUSIONThe effects of BM-MSCs transfected by pcDNA3.1-HGF on suppressing pulmonary alveolitis and early fibrosis induced by SiO2 were better than those of BM-MSCs. The mechanism may be associated with the reduced pulmonary inflammation.
