OBJECTIVEThis study aims to conduct a survey of the oral health status of disabled individuals in Liangshan Autonomous Prefecture in Sichuan province. This study was also conducted to prepare caries prevention planning in the region.

METHODSOn the basis of the Oral Health Surveys: Basic Methods of WHO and the Third National Oral Health Epidemiological Sample Survey Scheme, we investigated caries infecting disabled individuals who live in one big city (Xichang city), three counties (Bhutto county, Muli Tibetan autonomous county, and Huili county), and 46 towns and villages of Liangshan Autonomous Prefecture in Sichuan province, by multi-stage stratified and cluster sampling.

RESULTSAmong 3,439 disabled individuals, 2,085 were males and 1,354 were females; among these individuals, 815 live in the city and 2,624 live in rural areas. Furthermore, 2,177 were Han natives and 1,262 were Yi natives (ethnic). The caries prevalence rate and mean DMFT of disabled individuals in Liangshan Autonomous Prefecture in Sichuan province were 87.1% and 9.53, respectively. In Yi, the caries prevalence rate and mean DMFT of disabled individuals in Liangshan Autonomous Prefecture in Sichuan province were 85.8% and 9.93, respectively; in Han, the caries prevalence rate and mean DMFT of disabled individuals in Liangshan Autonomous Prefecture in Sichuan province were 87.9% and 9.29, respectively. No significant difference was found in the two groups of native (P > 0.05). A very low filling rate of 0.2% was also recorded.

CONCLUSIONDisabled individuals from Liangshan Autonomous Prefecture in Sichuan province exhibited a high prevalence of caries in permanent teeth. The oral health status of this special group of disabled individuals should be provided intensive care.

According to the super-position principle of the reinforcement of biological activities, a series of novel E-substituted 2, 3-diaryl propenoic acyloxy phosphonate derivatives were designed and synthesized. And the structures of the target compounds were confirmed by IR, 1H NMR, 13C NMR and elemental analysis. Furthermore, the cytotoxicities of all compounds on A-549, SGC-7901 and EC-109 in vitro were evaluated by MTT assay, and some of them showed good antitumor activity. Among the active compounds, especially, the IC50 value of compound 3e was (12.7 ± 1.9) μmol x L(-1) against A-549 cells, similar to cisplatin [IC50 = (8.0 ± 1.5) μmol x L(-1)], compounds 3g and 3k had better inhibition effect on EC-109 cells growth, with the IC50 values of (9.5 ± 1.8) μmol x L(-1) and (11.5 ± 0.9) μmol x L(-1) respectively, and compounds 3i and 3k exhibited good cytotoxic property on A-549, SGC-7901 and EC-109, which were worth further investigation.

OBJECTIVETo determine the effects of irrigation fluid absorption on system hemodynamics, fluid-electrolyte and hormone during mini-percutaneous nephrolithotomy.

METHODSIn this study 128 patients with renal calculus or calculus of superior ureter from January 2007 to February 2008 were collected. Hemoglobin (Hb), hematocrit (Hct), plasma osmotic pressure (POP), fluid-electrolyte, serum creatinine (Cre), renin, angiotensin II and aldosterone were determined before and after operation. Heart rate (HR), mean arterial blood pressure (MAP) and oxygen saturation (SPO(2)) were recorded dynamically every 30 min.

RESULTSThe HR speeded up accompanied with the irrigation time. When compared with before operation, POP, Cl(-), renin and Cre were significantly increased after operation; Hb, Hct and K(+) were significantly decreased after operation; MAP, SPO(2), Na(+), aldosterone and angiotensin II did not change significantly after operation. No serious surgery-related complication occurred in all patients.

CONCLUSIONSIrrigation fluid is absorbed during mini-percutaneous nephrolithotomy. The absorption amount is positively correlated with irrigation time. Changes of hemodynamics, fluid-electrolyte balance and renin may be caused by the irrigation fluid absorption.

OBJECTIVETo explore the level of serum uric acid (UA) in children with obstructive sleep apnea/hypopnea syndrome (OSAHS).

METHODBetween Sep. 2008 and Mar. 2010, 138 children with OSAHS were enrolled in study group. Sixty-five children with accessory auricle or ptosis of upper lid were enrolled into the control group. Furthermore, according to apnea/hypopnea index (AHI) or obstructive apnea index (OAI) the study group was further divided into three subgroups (mild, moderate and severe group). At last, the study group and control group were divided into two groups according to the body mass index (BMI), separately. The fasting serum UA level was compared among the different groups. Then the correlation between the serum UA level and AHI, BMI, oxygen desaturation index, least arterial oxygen saturation (LSaO(2)) and the percentage of total sleep time with arterial oxygen saturation < 0.92 was also analyzed in OSAHS children with or without overweight and obesity respectively.

RESULTThe difference of serum UA level between the study group and control group (z = -0.443), and the difference among the three groups (χ(2) = 1.241) was not significant(P > 0.05). The serum UA level in overweight and obese children [study group, 273.0 (238.3 - 357.3); control group, 298.0 (253.0 - 336.0)] was significantly higher than that in children with normal BMI [study group, 246.5(215.8 - 300.0); control group, 266.0 (224.0 - 303.3)] (z = -2.084, -2.214, P < 0.05). That serum UA level did not correlate with the above index of OSAHS was observed in children with or without overweight and obesity in study group (P > 0.05).

CONCLUSIONFindings of higher serum UA level were not observed in children with OSAHS. There was no correlation between serum UA level and the above indices of OSAHS. The serum UA level in overweight and obese children was significantly higher than that in children with normal BMI.

BACKGROUNDAntimicrobial peptides, including cathelicidin LL-37, human beta defensin (HBD)-2, and HBD-3, are important elements of the innate immune response and involved in modulation of the adaptive immunity, and they also play an important role in cutaneous defense against Mycobacterium tuberculosis.

METHODSThe fresh skin tissues and paraffin-embedded biopsy samples from three cutaneous tuberculosis, two tuberculids, and ten healthy individuals were collected. The expressions of LL-37, HBD-2, and HBD-3 mRNA in the lesions of three cutaneous tuberculosis and two tuberculids were detected by quantitative real-time polymerase chain reaction; the protein expressions were detected by immunohistochemistry and Western blotting methods.

RESULTSThe expressions of LL-37 mRNA and protein in the lesions of cutaneous tuberculosis and tuberculids were similar to that of normal skin. The expression of HBD-2 mRNA had an increasing trend in the lesions of cutaneous tuberculosis and tuberculids compared with that of normal skin; however, the expression of HBD-2 protein in the lesions of cutaneous tuberculosis had a decreasing trend compared with that of normal skin, and the expression of HBD-2 protein in the lesions of tuberculids was similar to that of normal skin. The expressions of HBD-3 mRNA and protein in lesions of cutaneous tuberculosis and tuberculids were similar to that of normal skin.

CONCLUSIONSOur study indicated that the expression of HBD-2 and HBD-3 mRNA and protein in lesions of cutaneous tuberculosis may be not consistent with that of tuberculids. However, an inherent limitation of the present study was that the sample size was small, and the roles and regulation mechanisms of LL-37, HBD-2, and HBD-3 in cutaneous tuberculosis and tuberculids need to be further investigated.

OBJECTIVEThe exercise rehabilitation in patient with chronic heart failure (CHF) is standard clinical practice, but it is rare using CardioPulmonary Exercise Testing (CPET) guide to prescribe exercise rehabilitation in China.

METHODSWe performed symptom limited maximal CPET in 10 patients with CHF, randomly divided into two groups: 5 patients as control without exercise and 5 exercise patients used Δ50%W intensity to exercise 30 min/d, 5 d/w, x12 w. Before and after 12 w rehabilitation, we evaluated functions.

RESULTSThere were no significant difference between two groups patients (P > 0.05). The exercise duration was increased from 8 min to 23 min after rehabilitation (P < 0.001); distance 6 minutes walking was increased from 394 m to 470 m (P < 0.05); score of Minnesota quality of life was decreased from 25 to 3 in exercise group (P < 0.01). However, there were nosignificant changes in control group (P>0.05) and their changes were smaller than those in exercise group (P < 0.01).

CONCLUSIONThe CPET guiding exercise rehabilitation is safe and effective for patients with CHF.

Polyhydroxyalkanoates (PHA) is a family of microbially synthesized polyesters consisting of various 3-hydroxyalkanoate monomers. Aeromonas hydrophila 4AK4 could be able to synthesize PHA copolymer consisting of 3-hydroxybutyrate (3-HB) and 3-hydroxyhexanoate (3-HHx). No data has been reported about the ability to synthesize the PHA with other monomers in A. hydrophila. In this study, propionic acid, valeric acid, heptanoic acid, nonanoic acid and undecanoic acid were used together with gluconate to find out whether A. hydrophila 4AK4 could synthesize the PHA consisting of odd carbon atom number monomers. The result showed that A. hydrophila 4AK4 could not growth when supplied with propionic acid, valeric acid, heptanoic acid and nonanoic acid and only undecanoic acid could be used to synthesize PHA. Wild type and recombinant A. hydrophila 4AK4 harboring phaA (beta-ketothiolase) and phaB (acetoacetyl-CoA reductase) were cultivated with undecanoic acid and glucose or undecanoic acid and gluconate served as carbon sources. PHA consisting of 3-HB and 3-hydroxyvalerate (3-HV) could be produced by both wild type and recombinant A. hydrophila 4AK4 and the latter could produce PHA with more 3-HB monomer. When the ratio of glucose or gluconate to undecanoic acid was 1:1, the cell dry weight (CDW) of A. hydrophila 4AK4 reached 1.14 g/L and PHA content was 60% of the CDW after cultivation for 24 h. When lauric acid and undecanoic acid were served as co-substrate, A. hydrophila 4AK4 could produce copolyester consisting of 3-HB, 3-HV and 3-HHx. Along with the increase of undecanoic acid proportion in the mixed carbon source, the 3-HV content of copolymer was increased while the 3-HB and 3-HHx content were decreased. In all cases, the CDW decreased along with the increase of undecanoic acid concentration, which indicated that undecanoic acid was not very good for A. hydrophila 4AK4 growth.

OBJECTIVETo investigate the treatment of postoperative chyle leak after surgery for digestive malignancies.

METHODSFrom December 2008 to February 2012, in the Sun Yat-sen Memorial Hospital of Sun Yat-sen University, clinical data of 19 patients with chyle leak after digestive system cancer surgery were retrospective analyzed.

RESULTSNineteen cases of chyle leak were all identified between the second and the fourth postoperative day and were all initially managed with conservative treatment including early fasting, parenteral nutrition(PN), 24-hour continuous infusion of somatostatin, and low pressure suction drainage. Eight patients were treated successfully for 6 to 10 days with a significant reduction of the daily drainage volume. Ten patients had enteral nutrition(EN) and their drain tubes were repeatedly washed with 30 ml of compound meglumine diatrizoate injection every day until the drainage volume decreased to 200 ml/day. The time to resolution of chyle leak in these ten patients ranged from 12 to 24 days. One patient had no significant decrease in fluid drainage and developed abdominal distension after one week of conservative treatment. Surgical closure of chyle leak was performed on the 11th postoperative day, abdominal cavity drainage tube was removed on the 4th postoperative day. The patient was discharged home in good condition.

CONCLUSIONMost postoperative chyle leak after surgery for digestive malignancies can be successfully managed with conservative treatment. Somatostatin and the drainage are the main therapeutic approaches. When chyle leak is not resolved with conservative treatment, surgical treatment should be considered to prevent serious complications.
