Simultaneous concurrence of subacute thyroiditis and Graves' disease is rare.We present one case of subacute thyroiditis with Graves' disease and combine with other reports to explore the clinical characteristics and therapeutic considerations.If subacute thyroiditis is considered coexisting simultaneously with Graves' disease,radioactive iodine uptake,thyroid autoantibody,fine-needle aspiration of thyroid gland,thyroid nuclide imaging examination,etc,should be done to make correct diagnosis and to adjust the therapeutic plan.

Objective To discuss effectiveness of gracilis muscle flap for treatment of degree 3 and 4 pressure ulcers on ischial tuberosities for elderly patients.Methods From January 2010 to June 2015,19 elderly patients with pressure ulcers on the ischial tuberosities were enrolled,including 11 males and 8 females with an average age of 71.3 years ranging 62 to 86 years.The average course of disease was 9.6 months ranging 2 to 23 months,including 7 cases of degree 3 and 12 cases of degree 4 according to the National Pressure Ulcer Advisory Panel (NPUAP).All cases were treated by gracilis musle flap after debridement.Results All muscle flaps survived without necrosis,2 cases had wound dehiscence after operation and were healed after symptomatic treatment,and the 17 wounds were healed for first intention.All patients were followed up for 6 months to 5 years.Pressure ulcer on the ischial tuberosities recurred in 1 case after operation and was healed by debridement and suture.Pressure ulcers did not recur in the rest cases.Conclusions Gracilis muscle flap in the treatment of degree 3 and 4 pressure ulcers on the ischial tuberosities has remarkable curative effect and high cure rate in elderly patients,it is worthy of clinical application.

Objective To investigate the clinical efficiency of applying tibial artery perforator flap to treat anterior medial incision poor healing one-stage after Pilon fracture.Methods From June,2012 to August,2015,13 cases of anterior medial incision poor healing after Pilon fracture,with tendon or plate exposure in patients and without acute infection,treated by tibial artery perforator flap to repair wound one-stage after thorough debridement.Results All the wounds were repaired by tibial artery perforator flap after a thorough debridement.There was flap necrosis in distal 1/3 part of flap in 1 case,which gained healing after debridement and skingrafting.The remaining 12 cases of flaps survived well.All patients were followed up for 5-14 months (mean 9.8 months),the flaps or skin grafts survived well,without tissue infection,osteomyelitis and other complication,and the functional recovery of the ankle was basically normal.Conclusion It is a simple and effective method by using posterior tibial artery perforator flap to treat anterior medial incision poor healing one-stage with non-acute infection after Pilon fracture on the basis of thorough debridement,worthy of clinical application and promotion.

Objective To discuss the clinical effect of the phase-one treatment scheme for traumatic osteomyelitis in tibia by combining flap,vancomycin-loaded calcium sulfate and autogenous iliac bone.Methods From January,2009 to July,2014,49 patients which had traumatic osteomyelitis in tibia and met the inclusive criteria were investigated and treated.By taking these patients as treatment group A(34 cases),they were treated by adopting the phase-one treatment scheme of combing tissue flap,vancomycin-loaded calcium sulfate and autogenous iliac bone.Fifteen patients who were treated by using the phase-one treatment scheme,namely,removing the lesion,implanting vancomycin-loaded calcium sulfate and repairing the defect by means of tissue flap,were chosen as control group B.Concerning treatment group A,drainage fluid was collected after operation every day to measure the concentration of vancomycin until drainage tube was removed.All the patients were followed up to study the following indexes:the standing time of drainage tube,the healing time of fracture,infection control rate,bone nonunion rate and other complications.Results All cases were followed up during 17 to 40 months after operation and no amputation was conducted for the affected limb.To repair soft tissue defect,flap and direct suture were adopted for 25 and 9 cases respectively in group A;The results indicated that all flaps survived,the poor healing of flap defect was observed for 2 cases which were healed after dressing change.However,to repair soft tissue defect,all group B cases used flaps;results revealed that distal flap necrosis was found in 2 cases applying neurocutaneous flap,with defect exudation and infection while the 2 cases were cured after debridement and dressing change without performing a second flap operation.In group A,3 cases recurred during 5 months to 2 years after operation;in group B,it was 1;other complications included pintract infection,nonunion,numbness of anterolateral thigh,hematocele in iliac 1 region.In group B,refracture occurred for 2 cases at the original lesion location 18 and 25 months after healing and was cured after plate refixation and the graft of autogenous iliac bone;intraoperative pathology validated no recurrence of osteomyelitis.The standing time of drainage tube was (12.53±4.56) days on average for group A while (17.07±3.87) days for group B;The difference was statistically significant (P＜0.05).The healing time of fracture was (6.20±2.16) months on average for group A while(8.36±2.84) months for group B.The difference was statistically significant(P＜0.05).Conclusion In one stage treatment of localized and diffused traumatic osteomyelitis,the scheme of combining tissue flap,vancomycin-loaded calcium sulfate and autogenous iliac bone effectively shortened the healing time of fracture,increased the healing strength,and reduced the exudation after operation,without increasing infection recurrence rate.The scheme was superior to merely implanting vancomycin-loaded calcium sulfate.

Objective To explore the predictive value of primary tumor site for loco?regional recurrence ( LRR) in early breast cancer patients with one to three positive axillary lymph nodes after radical surgery. Methods The clinical data of 656 patients pathologically diagnosed with pT1?2 N1 M0 breast cancer who received radical surgery without postoperative radiotherapy in our hospital from 1998 to 2010 were retrospectively analyzed. In those patients, 156 had primary tumor located in the inner quadrant, 45 in the central quadrant, and 455 in the outer quadrant. LRR and local recurrence?free survival ( LRFS) were end points. The Kaplan?Meier method was used to estimate LRR and LRFS rates. The log?rank test was used for survival difference analysis and univariate prognostic analysis. Multivariate analysis was performed using the Cox regression model. Results The 5?and 10?year sample sizes were 416 and 191, respectively. The 5?and 10?year LRR rates were 8?6% and 12?9%, respectively, while the 5?and 10?year LRFS rates were 86?2%and 76?4%, respectively. The univariate analysis indicated that age, pT stage, Ki67 level, molecular classification, and primary tumor in the inner quadrant were significant influencing factors for LRR ( P=0?000,0?006,0?017,0?004,0?000). The multivariate analysis showed that age no greater than 35 years, primary tumor in the inner quadrant, and non?luminal subtype in molecular classification were independent prognostic factors for LRR and LRFS ( P=0?0012,0?012,0?005) . With an increasing number of risk factors ( ≥ 2 ) , patients with primary tumor in the inner quadrant had a dramatically increased LRR rate and a reduced LRFS rate, while patients with primary tumor in the outer or central quadrant kept the same LRR and LRFS rates. Conclusions The primary tumor site holds promise for prediction of LRR and LRFS in patients with pT1?2N1M0 breast cancer after radical surgery. Patients with primary tumor located in the inner quadrant have a high LRR rate and a low LRFS rate, which provides an excellent predictor for the risk of recurrence in patients with high?risk breast cancer.

Objective To investigate the effect of staging treatment for diabetic leg ulcer by vacuum sealing drainage surgery (VSD) combined with perforator flap.Methods From Aug.2013 to Aug.2015,21 patients (in glycemic stability) with diabetic leg ulcer received the sustained VSD suction after a thorough debridement at the first phase and used perforator flap to repair the wound at second phase.Results After a thorough debridement and the sustained VSD suction,all the wounds were repaired with perforator flaps at the second phase.Postoperative flaps of 19 cases survived completely.Postoperative flaps of 2 cases appeared 1/4-1/5 area necrosis of distal flap and healed well after clear debridement.All patients were followed up in glycemic stability and all the flaps survived well without complications such as osteomyelitis and soft tissue infection.Conclusion Based on glycemic stability,VSD combined perforator flap in treatment of diabetic leg ulcers can control the infection and wound closure,which is worthy of clinical application and promotion.

BACKGROUND: Angiotensinogen (AGT) gene is the firstly discovered candidate gene for essential hypertension, both the T174M and M235T polymorphisms locate at the second exons of AGT gene, and there is existence of linkage disequilibrium. The polymorphism at A-6G and G-217A sites in promotor region plays an important role in regulating the gene expression, and the products of keep close correlation with the level of blood pressure. OBJECTIVE: To investigate the association between the polymorphism of AGT gene at A-6G, T174M and G-217A sites and the risk for the attack of essential hypertension in Chinese Han population, DESIGN: A cluster sampling and case-control analysis. SETTINGS: Department of Geriatrics and Department of Cardiology, the First Affiliated Hospital of Nanjing Medical University; Southern Research Center of National Human genome; Department of Cardiology, Dongtai People's Hospital of Jiangsu Province. PARTICIPANTS: The experiment was carried out in the countryside of Dongtai county, Yancheng city, Jiangsu province. All the subjects were selected from the countryside of Dongtai county, Yancheng city, Jiangsu province. Totally 177 patients with essential hypertension who had never accepted any drug treatment, were taken as the essential hypertension group, and hypertension was diagnosed according to the diagnostic standard of hypertension set by WHO/ISH in 1999 (systolic blood pressure ≥ 140 mm Hg and/or diastolic blood pressure ≥ 90 mm Hg); Another 86 normal person were taken as the normal control group. ② Inclusive criteria: The enrolled subjects should be Han nationality; long-term local residents but not from other places; able to answer questions clearly; diagnosed by disease history, clinical symptoms, physical signs and assistant examinations; have complete data of investigation of uniform questionnaires by face-to-face interview (including demographic information, profession history, family history and life styles of smoking, drinking, drinking tea, etc.). ③ Exclusive criteria: The patients with secondary hypertension in the essential hypertension group, subjects having family hisory of hypertension in the normal control group, and those with chronic diseases of liver and kidney, and diabetes mellitus in both groups were excluded. METHODS: Peripheral venous blood samples (3 mL) were collected, and DNA was extracted from human peripheral blood with FlexiGene DNA Kit (250). The Primer3 software was applied to design primers, and the polymorphism sites in the primer sequence were excluded. After multiplex polymerase chain reaction (PCR), 3 μL products were selected to detected the amplified results by agarose gel electrophoresis. The successfully amplified PCR products were purified with the QIAquick PCR Purification Kit, and the purified products were fragmentized with Dnase Ⅰ . The fragmentized products of enzyme digestion were labeled with fluorescein by deoxynucleotide terminal transferase. Two allele specific probes and one mismatched probe were designed respectively for each single nucleotide polymorphism. The chips were prepared with the OmniGridTM 100 TLC samler, each probe was repeated for three times to form three matrix. The hyridization solution was degenerated at 95 ℃ for 10 minutes, and then immediately cut on ice. 10 μL hybridization solution was added onto the chip matrix, hybridized at 50 ℃ for 2 hours, then washed and dried. The chips were scanned with the GenePix 4000B laser confocal scanner (Figure 2),and the intensity of the fluorescent signal for each probe was extracted with GenePix Pro, and the allele score of each single nucleotide polymorphism was calculated to judge the genotype. MAIN OUTCOME MEASURES: ① Comparison of the frequencies of genotype distribution at each polymorphism site of AGT gene in both groups; ② Correlation analysis of the polymorphism of AGT gene at A-6G and T-174M sites with the risk for the attack of essential hypertension; ③ Effects of the polymorphism of AGT gene at A-6G, T-174M and G-217A sites on blood pressure.RESULTS: According to the intention-to-treat analysis,all the 263 subjects were involved in the analysis of results. ① At the A-6G site of AGT gene, the frequencies of AA, AG and GG genotypes (P=0.014) and A and G alleles (P=0.004, OR=0.44) had significant differences between the essential hypertension group and normal control group; At the T174M site, the frequencies of CC, CT and TT genotypes (P=0.031) and A and G alleles (P=0.014, OR=0.55) were significantly different; At the G-217A site, no obvious differences were found in the GG, AG and AA genotypes (P=0.722) and G and A alleles (P=0.403, OR=0.80). ② The risk of essential hypertension in the individuals carrying AA genotype of A-6G polymorphism and CC genotype of T174M polymorphism was reduced by 57% (95%CI= 0.23-0.82, P= 0.010) and 56% (95%CI= 0.25-0.79, P= 0.006) respectively. ③ There were no significant differences in the systolic blood pressure, diastolic blood pressure and mean arterial pressure among different genotypes at the A-6G, T174M sites and G-217A sites (F=0.100- 2.911, P ＞ 0.05). CONCLUSION: The AA genope at A-6G and the CC genotype at T174M site of AGT gene may reduce the risk for the attack of essential hypertension in Chinese Hun population, and no significant correlation was found between the genotype of G-217A polymorphism and the attack of essential hypertension.

Objective: To investigate the brain function and their correlation with sleep beliefs and attitudes in adolescents with drug naive insomnia by using fractional amplitude of low frequency fluctuation, so as to provide a reference for the mechanism and treatment of insomnia. Methods: An insomnia group ( n =21) recruited first episode, drug naive, adolescents with insomnia who met the diagnostic criteria of the American Diagnostic and Statistical Manual of Mental Disorders(DSM-V). Healthy subjects matched with age, gender, and educational background were selected as the control group ( n =20). Pittsburgh Sleep Quality Index Scale (PSQI), Brief Version of Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16), 24 Items Hamilton Depression Scale (HAMD-24), 14 Items Hamilton Anxiety Scale (HAMA-14) were evaluated. Fractional amplitude of low frequency fluctuation was used for analysis, and Pearson correlation analysis was employed to quantify the correlation between peak values of brain regions with significant differences and the clinical scale scores of the two groups. Results: Compared with the control group, ractional amplitude of low frequency fluctuation(fALFF) values in the insomnia group were significantly decreased ( P <0.01, Alphaism corrected) in the left dorsolateral prefrontal lobe (L-DLPFC, MNI coordinates: -12, 60, 21, t =-3.85, K =495) and the left precuneus (MNI coordinates: -3, -54, 51, t =-4.29, K =417). The fALFF value of L-DLPFC in the insomnia group was positively correlated with DBAS-16 score ( r= 0.47 , P = 0.04 ). Conclusion Abnormalities in the L-DLPFC region suggest that adolescents with insomnia may suffer from impaired regulation of emotional and cognitive activities related to sleep.

Objective To analysis causes of the serious complications after the operation of the lower leg perforator pedicle screw flap, and to explore the corresponding countermeasures. Methods From June, 2012 to Au-gust, 2016, 60 cases of soft tissue defect of ankle and foot were repaired with propeller flaps pedicled with perforator of lower legs. with the area were soft tissue defect ranged from 3.0 cm ×2.0 cm to 19.0 cm ×9.0 cm, and all with bone exposure. Two cases of traumatic tissue defect, 7 cases were chronic osteomyelitis of the distal tibia, 13 cases were in-cision infection and necrosis after the operation of ankle joint fracture and Pilon fracture, 10 cases were simple inci-sion necrosis after calcaneal fracture, 18 cases were calcaneal osteomyelitis, 1 case were soft tissue defect after the ankle tumor operation, 6 cases were soft tissue necrosis after the Achilles tendon rupture, and 3 cases were soft tissue defect of the dorsum with infection. The posterior tibial artery perforator pedicled propeller flap was used in 18 cases. The pedicle of the vascular pedicle was 6.0-18.0 cm from the medial malleolus, the flap rotation was 135 °-180° . There were 42 cases of the perforator pedicle propeller flap of the peroneal artery, 5.0-18.0 cm from the pedicle of the vascular pedicle and 120°-180° rotation in the flap. The area of the flap was 9.0 cm ×3.0 cm-34.0 cm ×18.0 cm. There were 32 cases of direct suture in the donor site and 28 cases of free skin grafting. Results The color, swelling, elasticity, capillary reaction and healing of donor site were observed after operation. There was no flap ischemia occurred in 60 patients. Fourteen cases had venous reflux obstruction, all of which had swelling above II degree, 8 cases had swelling above III degree with obvious purple blood stasis, resulting in partial flap necrosis in 4 cases, all necrosis in 1 case, including 4 cases of free skin grafting, 1 case of flap transplantation and repair. There were 3 cases of necrosis after skin grafting in the flap area, all of which were partial necrosis. There was case of necrosis of the wound surface after di-rect suture of the donor site and 1 case of skin disintegration after disassembly, and all wounds healed after the replace-ment of the wound and the external use of the dried blood powder. All the 60 patients were followed-up for 12 to 30 (mean, 24.5)months. The flaps survived and the donor site scars healed well. The range of motion of the ankle was from-10°to 10°(mean, 5.6 °) and the flexion of the plantar was from 20 °to 50 °(mean, 37.8 °). Fourteen patients with venous reflux disorder were followed up for 15 to 28(mean, 22.3)months. The flap and skin graft survived well. Ankle dorsiflexion ranged from-10° to 10 °(mean, 2.4 °) and plantar flexion from 20° to 45 °(mean, 35.6 °). There was no obvious limp in walking. Conclusion Although the overall effect of the lower leg perforator pedicle propeller flap to repair the soft tissue defect of the foot and ankle is satisfactory, there are still various serious complications, which are mainly due to ia-trogenic. Doctors should strictly follow the basic principles of skin flap surgery from preoperative to postoperative, and during operation and postoperative management, so as to reduce the incidence of complications.

Objective:To determine the reliability and validity of the Chinese version of Fagerstrom Test for Nicotine Dependence (FrND) scale among smoking male inpatients with schizophrenia.Methods:Two hundred and twenty smoking male inpatients,who met criteria for schizophrenia of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ),were consecutively included.FTND scale and Russell's Reasons for Smoking Questionnaire (RRSQ) were used to assess subjects'severity of nicotine dependence and addiction score of the dimension of reason for smoking,respectively.According to the principle of voluntariness,37 subjects were selected and re-assessed with FTND scale after two-week interval.Reliability,correlation and factor analyses were used to examine the reliability and validity.Results:The Cronbach α (internal consistency) and two-week re-test reliability coefficients of FTND scale were 0.68 and 0.72 (P ＜0.01),respectively.The criterion related validity coefficient with addiction score of RRSQ was 0.53 (P ＜0.01).Two common factors were abstracted from the scale factor analysis,accounting for 52.4％ of the total variance.There were statistically significant differences between patients with different duration of illness,number of hospitalizations and age of smoking initiation (P ＜0.05).Conclusion:The Chinese version of FTND scale for smoking male inpatients with schizophrenia has a relatively low internal consistency and good re-test reliability,criterion related validity,construct validity and empirical validity.
