Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

Objective To assess the quality of life in patients with gynaeeological tumors and provide basis for clinical nurse.Methods 80 patients were investigated by the World Health Organization' s Quality of Life Questionnaire-Brief Version (WHOQOL-BREF) before and after operation.Results The patients had significantly lower scores in physiological and social relationship domains than the Chinese norms [(10.55 ±3.52) vs( 15.10 ± 2.30),( 10.93 ± 1.72) vs ( 13.93 ± 2.06 ) ;t =15.40,12.13,respectively; P ＜ 0.01 ].The patients had higher scores in environmental domain than the norms [(25.93 ± 3.93 ) vs ( 12.14 ± 2.08 ) ; t =49.07 ;P ＜0.01 ].No difference was found in scores in psychological domain between the patients and the norms (P＞0.05).No differences were found in the scores of all four domains among different types of gynaecological tumors (P＞0.05).Conclusions The quality of life will be damaged after suffering from gynaecological tumors,clinical nurses should improve self ability to promote patient rehabilitation and quality of life.

Objective To evaluate the development of the sphincter muscle complex(SMC)and defecation function in pediatric patients with congenital anorectal malformations(ARM).Methods A total of 64 children underwent MRI,among whom 39 were patients with ARM,and the others were patients without ARM undergoing MRI because of other dieases.The dimensions of the SMC in different planes were evaluated with different sequences and coils.The relationship between the SMC development and the defecation function was investigated.Results In control group,the absolute value of SMC width was (3.63?0.22)mm,which had a high correlation with age(r=0.998,P0.05).The SMCs in intermediate ARM patients[muscle index(MI)=0.47?0.05]and low ARM patients(MI=0.49? 0.05)were well developed.The SMCs in a portion of patients with high ARM(MI=0.28?0.06)were poorly developed,when MI≤0.18,anorectal contraction pressurewas significantly lower(t=3.55, P0.18[(0.85?0.20)vs(2.24?1.02)kPa].The length of anal canal with high-pressure[(10.88?3.64)vs(20.26?4.34)mm]was shorter(t=5.18,P0.18,the anorectal angle was less than 90 degrees,and normal continent function was found in 21 of 23 cases(91%).Conclusion MRI can be employed to evaluate the development of SMC in patients with ARM,MI was an objective criteria to evaluate the development of SMC.When MI≤0.18, maldevelopment of SMC will be highly suspected.

OBJECTIVE To explore the effect of water extract of notopterygium incisum (WN) on neuropathic pain and its molecular biological mechanism.METHODS Pain behavior test to detect the effects of WN on thermal hyperalgesia and me-chanical hyperalgesia in acute pain and chronic constriction injury(CCI)induced neuropathic pain model.Immunohistochemis-try and qPCR were used to detect the expression of TRPV1 .Calcium imaging was used to detect calcium influx of capsaicin (TRPV1 agonist) in CCI mice after oral administration of WN.RESULTS WN significantly reduced the thermal hyperalgesia and mechanical hyperalgesia in acute pain model and CCI model (P<0.001).The expression of TRPV1 in protein level and mRNA level in DRG neurons were significantly inhibited by administration of WN(P<0.05).The response of DRG neurons to capsaicin was significantly inhibited by the treatment of WN(P<0.001).CONCLUSION WN alleviated CCI-induced me-chanical allodynia and thermal hypersensitivity via modulating TRPV1 .Our results revealed a new molecular biological mecha-nism of analgesia effect to traditional Chinese medicine.

This study was aimed to summarize and analyze the morphology, immunophenotype, cytogenetics, molecular biology (MICM), tyrosine kinase (TK) gene mutations and clinical features of acute myeloid leukemia (AML) with complex variant of t(8;21). A retrospective study was performed for 20 AML patients with complex variant of t(8;21) in our hospital from January 1994 to April 2012, including analysis of clinical feature, immunophenotype, chromosome karyotype, treatment regimen, as well as the overall survival (OS) and relapse-free survival (RFS). Mutations of C-KIT, FLT3-ITD, FLT3-TKD and JAK2V617F were detected by genomic DNA PCR and the sequencing was per-formed in 13 AML patients with complex variant of t(8;21). The results showed that (1) the incidence of 20 AML patients with complex variant of t(8; 21) was 2.4% of total t(8; 21) AML patients. In 20 AML patients with complex variant of t(8;21), 1 case was M1, 17 cases were M2, 2 cases were M4; 10 cases were myeloid phenotype and the other 3 were myeloid plus lymphoid phenotype. There were 16 kinds of cytogenetics additional involvement of chromosomal breakpoints: lp22, 1p32, 2q35, 2q14, 3p25, 5q13, 6p22, 7q21, llq11, 1lq13, 12q14, 12q24, 12p12, 14q32, 15p13, 20q12. (2) C-KIT aberrations were detected in 30.8% cases, all mutated in exon 17 (mutkit 17), only 1 case had JAK2V617F mutation. The result of FLT3 mutation screenings in AML patients with complex variant of t(8; 21) was negative. Of 5 patients with gene mutations, 1 patient (20%) achieved complete remission (CR), the median RFS and median OS time were 6.5 months and 8.9 months respectively. Of the 8 patients without gene mutations, 6 patietns (75%) achieved CR; the median RFS and median OS time were 26.6 months and 27.7 months respectively. It is concluded that the AML patients with complex variant of t(8;21) shows typical features of t(8;21) AML, but the existence of the tyrosine kinase-related gene mutation has important implications on remission rate and long-term survival of patients treated by induction chemotherapy.

OBJECTIVETo explore the distribution and influence factors of protein C (PC), protein S (PS) and antithrombin (AT) activities and to determine the prevalence of their deficiencies in the Chinese Han healthy population.

METHODSHealthy volunteers including blood donors and individuals for routine check-up were recruited from 4 Chinese medical centers. The plasma levels of PC, PS and AT activities were measured. The plasma levels of activities were measured by chromogenic substrate assay (AT and PC) and clotting assay (PS).

RESULTSA total of 3493 healthy Chinese adults had been recruited in this study. Males had higher PS and PC activities than females, especially for PS (P < 0.01). PC activities increased with age in both sexes but decreased in men after 50 years old. There was no significant change with age were of PS in 50 years old, while there was a decline in males and a rise in females above 50 years old. AT tended to increase with age in women but decreased with age in men after 50 years old. Based on the age and gender, the general prevalence of PC, PS and AT deficiencies in the general Chinese Han population were 1.15%, 1.49% and 2.29%, respectively.

CONCLUSIONPC, PS and AT activities have correlation with age and gender in Chinese Han population. Reference range should be laid down and deficiencies should be identified

OBJECTIVETo explore the factors associated with retention in a community-based methadone maintenance treatment(MMT) among drug users in Urumqi.

METHODSWith national MMT guideline( drift) for heroine addicted drug users, local heroine-dependent people were admitted to community-based MMT program affiliated to Xinjiang Uigur Autonomous Region Center for Mental Health. Data on outpatients' social-demo characteristics, baseline behaviors on drug use and daily stabilized dose of drugs were entered to MMT database.

RESULTSUp to 10, Feb. , 2006,353 persons withdrew MMT treatment among 709 heroin dependant drug users. Between 11, Aug., 2005 and 10, Feb., 2006, with median duration as 77 days, cumulative drop-out rate of 90 days and 180 days after first dose of MMT were 73.8% among 455 and 99.4% among 355 drug users, respectively. The incidence of drop-outs was 29.8 per 100 person-month. The median length of stay (days) in MMT was 68.0 (95% CI: 59.0- 78.0). Correlates of retention were found as: Being Uigur(HR = 1.35;95% CI :1.09-1.67), duration of drug use (HR =0.74; 95% CI:0.55-0.99) and stabilized dose(HR = 0.60;95% CI: 0.48-0.74) was found in multiple Cox proportional hazard regression model.

CONCLUSIONRetention of MMT among drug users in Urumqi was low. Uigur people should be given individual counseling to help them increase the compliance rate. Within the ranges of clinic dosage, adjustment of the methadone dose on an individual base might serve as an appropriate approach to increase the effectiveness of the program.

OBJECTIVETo investigate the expressions of STAT5 phosphorylation in CD34(+)CD38(-)CD123(+) bone marrow cells of the patients with myelodysplastic syndromes (MDS), and then evaluate the level of activation of STAT5 associated with cell proliferation in MDS clone cells.

METHODSThe bone marrow mononuclear cells (BMMNC) were extracted from 36 MDS patients and 14 normal controls. The mean fluorescence intensities (MFI) of phosphorylated STAT5(P-STAT5) in CD34(+)CD38(-)CD123(+) and CD34(+)CD38(-)CD123(-)cells, with or without the stimulation of 10 U/ml EPO, were examined by flow cytometry (FCM).

RESULTSWithout stimulation, the P-STAT5 MFI in CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients was 113.71 ± 67.22/173.05 ± 102.78, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (58.84 ± 27.51/68.99 ± 50.42, P < 0.01, P < 0.05) and the normal controls CD34(+)CD38(-)CD123(-) cells (63.06 ± 21.06, P < 0.05), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal control CD34(+)CD38(-)CD123(-) cells; With the EPO stimulation, the P-STAT5 MFI in CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients was 144.04 ± 58.11/239.45 ± 152.05, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (68.41 ± 25, 10/64.21 ± 23.43, P < 0.01) and the normal controls CD34(+)CD38(-)CD123(-) cells (75.21 ± 27.02, P < 0.01), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal control CD34(+)CD38(-)CD123(-) cells; The P-STAT5 MFI in the CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients with or without EPO stimulation were 21.80/28.86, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (7.42/5.50, P < 0.01, P < 0.05) and the normal controls CD34(+)CD38(-)CD123(-) cells (6.39, P < 0.05), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal controls CD34(+)CD38(-)CD123(-) cells; There was no significant difference of P-STAT5 MFI with or without EPO stimulation and the increased P-STAT5 MFI between the CD34(+)CD38(-)CD123(+) cells of low and high risk MDS.

CONCLUSIONSTAT5 associated with cell proliferation was activated in CD34(+)CD38(-)CD123(+) bone marrow cells in MDS, which had more significant reactions to EPO than CD34(+)CD38(-)CD123(-) cells, indicating that CD34(+)CD38(-)CD123(+) bone marrow cells might be the real malignant MDS clone cells in MDS.
