Objective To analyze the dietary habits, energy intake and expenditure, anthropometrics, and body composition of the outpatients visiting the weight loss clinic of Beijing Hospital.Methods We pro-spectively enrolled 89 consecutive patients with body mass index ( BMI) ≥24 kg/m2 from November 2014 to August 2015 in the weight loss clinic of Beijing Hospital.There were 35 male and 54 female, with the mean age of (45.8 ±16.4) years.We divided them into two groups:the diabetes group (n=35) and the non-diabetes group (n=54), and compared the dietary habits, energy intake and expenditure, anthropometrics and body composition between the two groups.Results Regardless of diabetes, the overweight and obese patients all ate fast, mostly finishing a meal in about 10 minutes.They preferred Chinese food and meat, and disliked hot food.The frequency of dinning out in the non-diabetes group (3-5 times per week) was higher than that in the diabetes group (1-2 times per week) .Compared with the diabetes group, the non-diabetes group had higher fat-to-energy ratio [(34.9 ±7.6)%vs.(30.8 ±5.9)%], but lower carbohydrate intake [(232.2 ±59.7) g vs.(283.6 ±89.5) g], carbohydrate-to-energy ratio [ (47.9 ±8.3)%vs.(53.4 ±7.1)%], and the ratio of resting metabolic rate to body weight [ (66.9 ±9.6) kJ/(d? kg) vs.(71.1 ±7.9) kJ/(d? kg)] (all P<0.05).There were no statistically significant differences between the two groups in total energy intake, pro-tein intake, high quality protein intake, fat intake, protein-to-energy ratio, and resting metabolic rate (all P>0.05).Anthropometrics showed that the mean BMI of the patients was (32.8 ±4.4) kg/m2, with the maxi-mum being 53.5 kg/m2.The hip circumference [ (117.15 ±9.9) cm vs.(111.1 ±8.2) cm], upper arm circumference [ (36.4 ±3.8) cm vs.(34.0 ±3.3) cm], and triceps skinfold thickness [ (36.1 ±8.9) mm vs.(31.6 ±8.8) mm] were larger in the non-diabetes group than in the diabetes group (all P<0.05), but the mean age was lower in the non-diabetes group [ (41.7 ±16.9) years vs.(52.9 ±13.1) years) (P=0.01).There were no statistically significant differences between the two groups in body weight, BMI, waist circumference, neck circumference, and bilateral hand grip strength (all P>0.05).According to body compo-sition analysis, the body weight [ (94.8 ±18.3) kg vs.(86.9 ±17.2) kg], body fat mass [ (39.7 ± 11.3) kg vs.(33.5 ±8.9) kg], body fat percentage [ (41.7 ±6.5)%vs.(38.5 ±6.7)%], and visceral fat area [ (145.3 ±24.8) cm2 vs.(130.7 ±27.5) cm2 ] were larger in the non-diabetes group than in the di-abetes group ( all P<0.05) .There were no statistically significant differences between the two groups in BMI and skeletal muscle mass (both P>0.05).Conclusion Compared with diabetes patients, overweight and obese non-diabetes patients may be younger, having worse dietary habits, and having larger body fat mass, body fat percentage, and visceral fat area.

Objective To investigate the safety and efficacy of technical modification for laparoscopic repair of giant hiatal hernias.Methods A total of 49 patients with giant hiatal hernia underwent modified laparoscopic repair by dissecting sac, closing hiatal, mesh placement and fundoplication from June 2010 to May 2014.The operation time, hospitalization time, postoperative complications, upper gastrointestinal imaging and improvement of postoperative symptoms were observed.Results The average operation time was (103.6 ±31.7) min(88-173min).The average length of post operation hospitalization was (4.2 ± 1.8) d (range,3-12d).Postoperative complication occurred in 4 patients,including pleural effusion (1 patient),respiratory failure (1 patient), difficulty in swallowing (2 patients)with complication occurrence rate being 8.2％ (4/49).No conversion or death occurred.The average time of follow-up was (28.3 ± 12.7) months (6-50 months) in 49 cases.During the follow-up, main symptoms were relieved and no recurrence was found by barium swallow.Conclusion Technical modification for laparoscopic repair of giant hiatal hernias is safe and effective.

Rat models of diabetes were established by injecting streptozocin intraperitoneally.According to random number table,three groups were divided:normal group,diabetic group,and fisetin-treated group.After 24 weeks,all rats were sacrificed.Biochemical parameters of blood and urine samples were tested.The pathological changes were observed by paraffin sections staining with HE.The expression of extracellular matrix proteins was analyzed via PAS and Masson staining.Location of p300 protein expression was analyzed by immunohistochemistry.The protein expressions of p300 and MMP-2 were determined by Western blotting.The mRNA expressions of MMP-2 were analyzed via real-time PCR.The biochemical parameters and kidney pathological images in fisetin-treated group were better than those in diabetic group.The expression of extraeellular matrix proteins was lower than that in diabetic group.Immunohistochemistry analysis showed that among three groups the expression of p300 was mainly in glomeruli,and was also expressed in cell nucleus and cytoplasm and the coloration of fisetin-treated group was weakened as compared with diabetic group.Western blotting analysis showed that the expression of p300 protein in fisetin-treated group was lower than that in diabetic group(P＜O.05).The expressions of MMP-2 mRNA and MMP-2 protein were higher than those in diabetic group (P ＜ 0.05).It is suggested that fisetin may attenuate diabetes associated abnormalities in the kidney of rats,owing probably to inhibiting the expressions of p300 and enhancing the expressions of MMP-2.

Objective To investigate the changes of serum apolipoprotein A-I and its clinical significance to acute respiratory infection.Method Totally 44 patients with acute respiratory infection were divided into three groups according to various concentration of Serum apolipoprotein A-I.They were procaleitonin(PCT)＜0.5 ng/ml group,0.5 ng/ml≤PCT＜2 ng/ml group and PCT≥2 ng/ml group.We measured apolipoprotein A-I,C-reactive protein,procalcitonin and albumin within 24 hours after admission.Results With the increase of serumPCT,the production of ApoA-I and albumin were down-regulated,while CRP up-regulated.Conclusions Apolipoprotein A-I has a sound relationship with the acute respiratory infection.It can be used as one of the diagnostic criteria in severe infection patients who have disorders of lipometabolism.

Objective To investigate the safety and effectiveness of mesh and non-mesh techniques in laparoscopic repair of large hiatal hernias (LRLHH).Methods A retrospective clinical controlled study of mesh and non-mesh techniques in LRLHH form January 2006 to August 2014 was performed.Results A total of 83 and 36 patients were recruited to mesh and non-mesh group respectively.There were no significant differences in operation time,operation bleeding volume,hospitalization time or complications between the two groups.Main symptoms were significantly improved during the postoperative long-term follow-up in both groups.The improvement of dysphagia in mesh group showed no significant difference [22.9％ (19/83) VS 12.0％ (10/83),P=0.066],however,non-mesh group showed significant difference [30.6％ (11/36) VS 5.6％ (2/36),P=0.006].Rate of dysphagia alleviation in non-mesh group was significantly higher than that in mesh group [25.0％ (9/36) VS 10.8％ (9/83),P =0.048].Mesh-related complications of esophageal erosions occurred in 5 patients (6.0％) in mesh group,including esophageal stenosis in 3 patients,esophageal-cardiac stricture in 1 patient.Recurrent hernia occurred in 1 patient (1.2％) in mesh group and 3 patients (8.3％) in non-mesh group (P =0.082).Conclusion LRLHH with mesh should be individualized.The use of mesh in LRLHH reduces the recurrence rate,but may lead to some complications.

OBJECTIVE: To explore the function of outer hair cells and its influencing factors in the workers of occupational exposure to low frequency electric and magnetic fields. METHOD: 502 high-strength LF EMFs-exposed workers were taken as the study subjects. The field intensity indicator and noise analyzer were employed for the examination of the electromagnetic energy intensity and noise value at the working sites. Self-administered questionnaires were adopted. Universal hearing screening by distortion product otoacoustic emission (DPOAE) and pure tone audiometry (PTA) were done. 100 workers who had abnormal POAE were taken as the observation group and 100 workers who had normal DPOAE were taken as the control group. The workers need be confirmed with ABR testing when the pure tone threshold of two consecutive frequencies were above 20 dB HL or DPOAE detection in any frequency did not pass. Multiple factor analysis with logistic regression was performed for the risk factors. RESULT: The average electric power density in job locations was 21-38 KV/m, which was higher than national standard (< 5 kv/m). Average noise-level in job locations was 52-65 dBHL, which was within the standard (< 85 dB(A). Questionnaire presented that low frequency electric and magnetic fields might increase the incidence of headache, insomnia and tinnitus in the observed group. The incidence of abnormal DPOAE was higher in the subjects of the observed group (P < 0.01). At 676, 933, 3616, 5 130, 7253 Hz, the DPOAE amplitudes of the observed group workers were significantly lower than the control group. Multivariate analysis showed that the risk factors of abnormal DPOAE included exposure of EMF, length of service, daily exposure time, conservatory measures might be protective factors. CONCLUSION The changes of DPOAE indicated that the exposure to low frequency electric and magnetic fields had a subtle, discreet and localized impairing effects on outer hair cells. Exposure of low frequency electric and magnetic fields, length of service, daily exposure time might be risk factors, conservatory measures might be protective factors.

Objective To explore the best way for clinical screening of primary aldosteronism (PA).Methods Three hundred and three suspected cases of PA were collected and divided into groups of primary aldosteronism group, essential hypertension group, and nonsecreting cortical adrenal tumor group.The plasma aldosterone concentration/plasma renin concentration ratio ( ARR) was used to draw the receiver operating characteristic ( ROC) curve and obtain the best cut-off point.Furthermore, the current screening schemes for PA were compared.Results Upright ARR yield had larger areas under the ROC curve than plasma aldosterone concentration or plasma renin concentration under all conditions of testing. The best cut-off point of upright ARR[(pg/ml)/(μIU/ml)] for the diagnosis of PA was 43.45.During the two postural stimulation tests,the two upright ARR exceeded 43.45 with the highest diagnostic sensitivity of PA reaching 0.94.During the two upright tests ARR was less than 43.45, with a sensitivity of 0.74, and a specificity of 0.94.Conclusion To screen for PA in high-risk populations, twice postural stimulation test is recommended.As long as the upright ARR is above 43.45, PA may be considered and further confirmation is needed to prevent misdiagnosis.
