OBJECTIVETo reconstruct tracheal defect after tumor excision, we used the contralateral musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum.

METHODSThe contralateral musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum was used to reconstruct the tracheal defect when the blood supply to the ipsilateral sternocleidomastoideus was destroyed because of lymphonode clearing or radiotherapy. The pedicle of the musculo-periosteum flap was dissected adequately and the blood supply was protected carefully.

RESULTSAll flaps survived with epithelization and osteogenesis. The endotracheal tubes were pulled out safely without trachea stenosis in all the patients.

CONCLUSIONSThe contralateral musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum could reconstruct the tracheal defect when the ipsilateral blood supply was damaged. This method extends the application of the musculo-periosteum flap.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

adrenocorticalcarcinoma；cortisolhypersecretion；hypokalemia；prognosis 【Objective】To analyze the prognostic determinants of adreno cortical carcinoma（ACC）inadults.【Methods】Alladult patients who were admitted to SunYat-sen Memorial Hospital，SunYat-sen University from December 2011 to March 2017 and pathologically diagnosed ACC were included in this study.Thec linical data and preoperative laboratory examinations of those patients were analyzed retrospectively. Overall survival or disease-free survival was calculated and survivalcurves were plotted by Kaplan-Meier and compared by log-rank test. Harzardratios（HRs） with their 95% confidenceintervals（CIs） were calculated by univariate and multivariate Coxregression model.【Results】The study included 20 adult patients with ACC， with a median follow-up of 13months （6~73 months）. The mean survival time of those patients was 49.2 months（6~73months），with a 1-year survival rate of 70.0%. The results of multivariate Coxregression analysis revealed that the presense of cortisol hypersecretion（HR=23.60，95%CI：2.49-223.79，P=0.006） and hypokalemia（HR=23.60，95%CI：2.49-223.79，P=0.006）were predictors of poorprognosis of ACC. Moreover，in 18 patients with completely resected ACC，the presense of hypokalemia resulted in a worse disease-free survival.【Conclusion】The presense of cortisol hypersecretion and hypokalemiaare independent risk factors associated with poorprognosis of ACC in adults.​

OBJECTIVETo investigate the changes of hipbone biomechanics after the resection of ischiopubic tumors and their relationships with the complications in the convalescent stage, and directing the postoperative pelvic reconstruction.

METHODSDICOM data were used to create an intact hipbone finite element model and postoperative model. The biomechanical indices on the same region in the two models under the same boundary condition were compared. The differences of displacement, stress, and strain of the two models were analyzed with statistical methods.

RESULTSThe distribution areas of the hipbone nodes' displacement, stress, and strain were similar before and after the simulated operation. The sacroiliac joint nodes' displacement (P=0.040) and strain (P=0.000), and the acetabular roof nodes' stress (P=0.000) and strain (P=0.005) of two models had significant differences, respectively.But the sacroiliac joint nodes' stress (P=0.076) and the greater sciatic notch nodes' stress (P=0.825) and strain (P=0.506) did not have significant differences.

CONCLUSIONSThe resection of ischiopubic tumors mainly affect the biomechanical states of the homolateral sacroiliac joint and acetabular roof. The complications in the convalescent stage are due to the biomechanical changes of the sacroiliac joint and the acetabular roof and disappearances of the stabilization and connection functions of the pubic symphysis and superior ramus of pubis.

OBJECTIVETo detect and distinguish Streptococcus mutans (S. mutans) and Streptococcus sobrinus (S. sobrinus) quickly in epidemiology and investigate the distribution of S. mutans in the oral of children with rampant caries.

METHODSDesigned minor groove binder (MGB) probes according to the gtf gene of S. mutans and S. sobrinus. Detected 9 reference strains of Streptococcus mutans group by MGB probes in real time and after cultivation. Evaluated the results of these two methods. 92 dental plaques from pre-school children with rampant caries were detected in real time with MGB probes.

RESULTSThe primers could amplify the target sequences specificity and distinguished S. mutans and S. sobrinus from each other using MGB probes. Though the fluorescence occurred earlier in S. mutans than in S. sobrinus, they had the same results in nature. In 92 children with rampant caries, the detective ratio of S. mutans was 96.7% and that of S. sobrinus was 32.6%. All the samples which could detect S. sobrinus were positive for S. mutans.

CONCLUSIONThe primers and probe designed from gtf genes of S. mutans and S. sobrinus can amplify the target sequence and distinguish them from each other in real time.

OBJECTIVETo study the inhibitory effects of celecoxib, a cyclooxygenase-2 inhibitor, on the proliferation of hepatocellular carcinoma cells.

METHODSThe in vitro inhibitory effects of celecoxib at different concentrations and for different treatment time lengths on human liver cancer cell line SMMC-7,721 were observed with MTT assay, and flow cytometry was performed to detect the cell cycle changes. The in vivo tumor inhibition effect of celecoxib was evaluated in Kunming mice bearing transplanted tumor derived from liver cancer cell line H22 transplantation.

RESULTCelecoxib significantly inhibited the in vitro growth of human liver cancer cell line SMMC-7721 in a time- and dose-dependent manner. A 36-hour celecoxib treatment (40 micromol/L) resulted in decreased SMMC-7721 cell proliferation and an increase of the cell percentage in G1 phase from 44.7% to 49.9% with decreased cell percentage in S and G(2)/M phases from 55.4% to 50.1%. In the mice bearing H22 transplanted tumor, celecoxib showed significant inhibitory effect on the growth and local metastasis of the transplanted tumor.

CONCLUSIONCelecoxib can inhibit the proliferation of different liver cancer cell lines both in vitro and in vivo, and therefore may serve as an important candidate drug for prevention and treatment of hepatocellular carcinoma.

Aims: The South China Sea (SCS) harbours a rich biodiversity. However, few studies have been published on its diverse communities, particularly its microbial counterparts. As key players behind many of the vital processes carried out in the ocean, microbes are the focus of this study, placing particular emphasis on community composition, structure, and function. Methodology and results: By employing next generation shotgun sequencing technologies (Illumina HiSeq2000), we assessed the taxonomic structure and functional diversity of the prokaryotic communities in surface waters collected from 3 representative sites in the Eastern SCS: Sarawak (Kuching), Sabah (Kota Kinabalu), and Philippines (Manila). Comparisons were undertaken to similar studies from coastal and open ocean environments. All 3 locations were dominated by members of the Proteobacteria (Alpha- and Gamma-) and Cyanobacteria (Synechococcus sp. and Prochlorococcus sp.). The highest proportion of Gammaproteobacteria was found in Sarawak, representing an approximate 20% of total sequences. Archaeal assemblages were made up largely of Euryarchaeota and unclassified sequences, while Crenarchaeota and Thaumarchaeota were present in much smaller proportions, except in the Philippines where Thaumarchaeota made up almost 40% of the entire taxa. Conclusion, significance and impact of study: The majority of the microbial communities adhered to a core set of functional genes across the different locations. However, differences existed particularly in Sarawak waters which are hypothesized to be due to local environmental parameters such as riverine influence. The results obtained from this study provide the first comparison of prokaryotic communities in the surface waters of the eastern SCS and will serve as a good platform for prospective studies in the field of environmental science.

Objective To understand the variation of thyroid hormones in each trimesters of pregnancy in women.Methods A total of 1 839 pregnant women in different trimesters were enrolled and thyroid hormones including FT3,FT4,TT3, TT4,TSH,TGAb and TPOAb were measured.The reference range of hormone in each trimester was calculated.Results There were statistically differences in all thyroid hormones among all trimesters of pregnancy women (P<0.05 )except for TT4 between the early and middle trimesters (P>0.05 ).The median of FT3 and FT4 were gradually reduced as the pregnant trimester grew up while the median of TSH had the adverse tendency.The median of TT3 was highest during the middle trimester (1.47 nmol/L).TT4 median was lowest during the late trimester (80.67 nmol/L).The TSH level of pregnant women over 30 years old was significantly lower than that of below 30 age group during all trimesters(P<0.05 ). There were significant differences in FT4,TT3 and TT4 level among early and middle trimesters among different ages groups(P<0.05 ).The positive rates of TGAb and TPOAb during late trimester (4.74% and 1.63%)were significantly lower than those of early trimester (1 4.40% and 5.56%)and middle trimester (1 4.40% and 5.56%)(P<0.05 ). Conclusion Significant differences of thyroid hormones are found not only in different stages of pregnancy,but also in different ages.Therefore,establishing trimester-specific reference data of thyroid hormones during different pregnency may be important for clinical practice.
