Objective To explore the new way of the differential diagnosis of malignancy-related and non-malignant ascites.Methods 152 patients included 66 cases of liver cirrhosis, 21 cases of tuberculousperitonitis, 38 cases of hepatocellular carcinoma and 27 cases of other malignant tumors with ascites were studied. The levels of tumor markers (AFP, CEA, CA19-9 and CA125) in sera and ascites were measured.Results The diagnostic sensitivity of AFP, CEA, CA19-9 and CA125 in the malignancy-related ascites were 75 0%, 73 8%, 63 6% and 66 7%, respectively. And the specificity were 86 4%, 77 6%, 88 4% and 74 1%, respectively. The level of serum AFP, CEA, CA19-9 and CA125 were remarkably higher in malignancy-related ascites than that in non-malignant ascites(P

0.05 ) respectively. Before and after irradiation in the group of 100 mJ, the ratio of G 2+ /P 2+ was 1.667?0.128 and 2.135?0.156( P 0.05 ). Conclusion: The normal pulsed Nd:YAG laser irradiation alone can not increase acid residence of the enamel.

Objective To investigate bone strength in adults,and explore its influencing factors. Methods One hundred and ninety-one adults undergoing health examinations were selected.The questionnaires about milk intake and exercise conditions were performed,the body weight,fat mass,body mass index(BMI)and calcaneal bone strength were measured,and the relationship between each parameter and bone strength was analysed. Results Bone suength decreased with age increase,and was higher in males than that in females.Bone strength of overweight to obese adults was higher than that with normal body weight(P<0.05).Bone strength of adults with high milk intake was higher than that of those with low milk intake(P<0.05).Multivariate analysis revealed that age was negatively related to bone strength,females were more susceptible to bone strength decrease,and BMI and milk intake were positively related to bone strength. Conclusion Gender,age,BMI and milk intake are main influencing factors for bone strength.Bone strength decreases with age increase,and increase of BMI and milk intake will benefit bone strength,especially for females.

This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.

Objective To study mother and infant's iodine metabolism and thyroid function during lactation with different iodine intakes. Methods Wistar rats were randomly assigned to four groups with severe iodine deficiency (SID), mild iodine deficiency (MiID), normal iodine (NI), and excessive iodine (ExI) intake respectively. All rats were fed on an iodine deficient food and drinking water with different quantities of potassium iodide for 3 months until mating. The urinary iodine, milk iodine, blood iodine, and thyroid hormones (TH) were detected in lactating mother and the offspring rats 14 days after birth. Thyroid weight of mother rats was determined. Thyroid morphology of mother and their offsprings was observed. Results ( 1) Iodine contents in urine, milk, and blood of lactating rats and the offsprings were increased with the increase of iodine supplied in diet. But the change in amplitude between groups was decreased in the other; urine iodine > milk iodine > blood iodine. (2) Serum TT4[ (16. 7±12. 0 vs 36.4±15. 0) nmol/L, P<0.05] was significantly decreased, but TSH [(5.73±2.90vs 1. 38±0.30)mIU/L, P<0.01]and TT3/TT4(6.6±2.7 vs 2. l±0.3,P<0.01) were increased in lactating rats of SID group compared with NI, so as TT4( 10.6±2. 3 vs 16.4±4. 7) nmol/L, P<0.05 ] of offspring rats in SID, but were not in MiID and ExI groups. (3 ) Histological studies showed that small follicular thyroid nodules with follicular hyperplasia occurred in both lactating rats and their offsprings in the SID group, mild swelling in MiID group and polymorphism changes appeared in mother rats of ExI group, but no significant difference appeared in offsprings compared with NI group. Conclusions Severe iodine deficiency will lead to hypothyroidism in mother and infant, but normal iodine nutrition and thyroid function in mother and offspring were maintained through the compensatory action of mother and child in mild iodine deficiency and iodine excess.

Objective To discuss the influence of preoperative family purge care for the quality of life of patients with long type of congenital Hirschsprung′s disease (HD) who had enterocolitis history in neonatal period. Preoperative family purge care, which can shorten the HD postoperative treatment, improve the quality of life. Methods A total of 40 cases of patients with long type of congenital HD who had enterocolitis history in neonatal period received 1-stage radical preoperative by family phone call. Nineteen cases from January 2010 to February 2013 were as normal group and 21 cases from March 2013 to April 2016 were as improved group. Routine family purge nursing care 3-6 months were used in both the groups, while the combined nursing care of expanding anus were used in the improved group in addition. Evaluated the effects of postoperative observation indicates: the first defecation time, length of hospital stay, time needed for expanding anus, patency rate of defecation and not patency rate in 9-12 days, need enema intervention to assist defecate rate after postoperative 1 year, the recurrence of enterocolitis at 1-3 years after operation. Results The first defecation time, length of hospital stay, time needed for expanding anus were (39.15±8.23) h, (7.89±0.82)d, (5.17±0.98) min in normal group, (23.79± 7.54) h, (7.10± 0.29) d, (3.15±0.73) min in improved group, and there were significant differences between two groups (t=6.13, 5.46, 15.54, all P<0.01). The patency rate of defecation and not patency rate in 9-12 days were 12/19, 7/19 in normal group, 100.00%(21/21), 0 in improved group, and there were significant differences between two groups (χ2=9.38, P<0.01). The intervention rate of no need for enema, occasionally enema, often enema were 2/19, 12/19, 5/19 in normal group, 76.19%(16/21), 23.81%(5/21), 0 in improved group, and there were significant differences between two groups (χ2=18.25, P<0.01). There was no significant difference in the recurrence of enterocolitis at 1, 2, 3 years after operation between two groups (χ2=2.33, P>0.05). Conclusions Patient with long type of congenital HD who had enterocolitis history in neonatal period neonatal period,received family enema and expanding anus in 3- 6 months before 1-stage radical preoperative can shorten the postoperative HD treatment, improve the quality of life.

Objective To apply the virtual reality in balance function training for Parkinson's Disease (PD). Methods From October, 2013 to January, 2016, 31 patients with balance disorders after PD were divided into two groups:the treatment group (n=17) received virtual reality balancing games training, while the control group (n=14) received routine balance training. They were assessed with Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), static fall index (SFI), limits of stability (LOS), dynamic fall index (DFI) and modified Barth-el Index (MBI) before and four weeks after treatment. The frequency of falls in the next six weeks was recorded. Results The scores of BBS, TUGT, SFI, LOS, DFI and MBI improved significantly in both groups after treatment (P<0.05), and improved more in scores of BBS (t=2.095), TUGT (t=-2.091), DFI (t=-2.182), LOS scores (t=2.202) and MBI (t=3.036) in the treatment group than in the control group (P<0.05). There was positive correlation between scores of BBS and MBI (r=0.899, P<0.001). The frequency of falls was less in the treatment group than in the control group (P<0.05). Conclusion Virtual reality balance training can improve the balance function for PD.

Objective To observe and compare the different orthotopic models of papillary thyroid cancer ( PTC) cell lines of RET/PTC1 rearrangement and BRAFV600E mutation in nude mice. Methods Human PTC cell lines TPC-1, BHP5-16 and BHP2-7 were used. The genotypes of RET/PTC1 rearrangement and BRAFV600E mutation were determined by realtime-PCR and DNA sequencing analysis. The cells(2×105) were injected into the thyroid gland of nude mice. The nude mice were executed at 4th, 12th week, and then their thyroid tumors were removed and weighed. The levels of thyroid hormone were detected using chemiluminescent immunoassay. Results Both TPC-1 and BHP2-7 cells were identified as RET/PTC1 rearrangement by real time-PCR, and the expression of RET/PTC1 rearrangement in BHP2-7 cell was higher than that of TPC-1 cell. BRAFV600E mutation was found in BHP5-16 cell by DNA sequencing analysis, but was not found in TPC-1 and BHP2-7 cells. There were different characteristics in three orthotopic nude model groups. Tumorigenic rates of TPC-1 and BHP5-16 groups were 100%, but the growth of tumor was more rapid in BHP5-16 group than that in TPC-1 group, with more weight tumor. The changes of thyroid hormone levels in BHP5-16 group and TPC-1 group were the same, which were normal at 4th week and sharply decreased at 12 th week(P<0. 05). However, the tumorigenic rate of BHP2-7 group was only 6. 25%. Compared with normal control group, there was no statistical difference in the levels of thyroid hormone in BHP2-7group(P>0. 05). Conclusions It showed difference in the orthotopic models of PTC cell lines of RET/PTC1 rearrangement and BRAFV600E mutation in nude mice. BRAFV600E mutation has obvious impacts on increasing tumorigenic rate and promotion of tumor growth in the orthotopic model. It should not be ignored that advanced thyroid tumor will lead to the destruction of thyroid function.

ObjectiveTo investigate the effects of maternal thyroid dysfunction during pregnancy caused by iodine deficiency of different degrees on doublecortin ( DCX ) and synaptophysin ( p38 ) expressions in fetal brain.Methods Wistar female rats were randomly divided into four groups:adequate iodine ( AI),mild iodine deficiency ( MiID ),moderate iodine deficiency ( MoID ),and severe iodine deficiency ( SID ),according to the total daily iodine supply( fed on an iodine deficient diet with different dosages of KI added in drinking water).Three months later the rats were mated.Serum TSH and thyroid hormones were determined in maternal rats on gestational day 20 using chemiluminescent immunoassay.The iodine contents in urine and histological changes of thyroid gland were observed in pregnant rats.The mRNA and protein levels of DCX and synaptophysin ( p38 ) were analyzed in fetal brain by using real time quantitative RT-PCR and western blotting respectively.Results( 1 ) Iodine contents in urine of pregnant rats were reduced with the decrease of their iodine supply.Compared with group AI,serum TSH was significantly increased [ ( 2.95 ± 1.70 vs 1.31 ± 0.55 ) mU/L,P ＜ 0.05 ],and both TT4 and FT4 were significantly decreased [ ( 14.3±4.1 vs 28.4±19.3 ) nmol/L,P＜0.05 ] and [ ( 10.8±3.6 vs 20.2±8.0) pmol/L,P＜0.01 ] in pregnant rats of SID group.Whereas,a slight rise in TSH,and a mild decline in both TT4and FT4 were found in MoID and MiID groups.However,there were no significant changes in TT3 and FT3 levels among these four groups.( 2 )Histological characteristics of thyroid gland in pregnant rats showed a typical goiter with small follicular hyperplasia and lack of colloid in SID group,moderate follicular hyperplasia with decreased colloid in MoID group; but mild cellular hyperplasia without decrease in follicular size and colloid in MiID group.( 3 ) The mRNA levels of DCX were increased in fetal brains of three iodine deficiency groups compared with AI group,but a statistical significance was found in MoID group.The protein levels of DCX in all experiment groups were significantly increased.Both mRNA and protein expressions of synaptophysin ( p38 )were significantly down-regulated in three iodine deficiency groups.Conclusions Maternal thyroid dysfunction caused by iodine deficiency,even by mild or moderate iodine deficiency,may lead to retardation of fetal neuronal and synaptic growth.
