1.Ultrastructural characteristics of synovial effusion cells in some arthropathies.
The Malaysian journal of pathology 2004;26(2):73-87
OBJECTIVE: To evaluate the range of activation changes of polymorphonuclear leukocytes (PMN) and the ratio of apoptosis and necrosis in synovial effusions of patients with various arthropathies, and to reveal possible correlations with clinical variants of joint inflammation. METHODS: Synovial effusions were aspirated from the knee joints of patients with rheumatoid arthritis (RA, 28 cases), and seronegative spondyloarthritides (SSA): Reiter's disease (RD, 9 cases), peripheral form of the ankylosing spondyloarthritis (6 cases) and psoriatic arthritis (6 cases); and primary osteoarthritis (OA, 9 cases). Cytospin preparations were processed for transmission electron microscopy and assessed for the incidence of apoptosis, necrosis, and cytophagocytic cells (CPC) in the synovial fluid (SF). The range of activation changes of the neutrophil granulocytes, the dominating cell population in the arthritic SF, was evaluated. RESULTS: In all arthropathies under investigation most of the synovial effusion cells had intact ultrastructure with a certain amount of apoptotic cells dominating over the cells with signs of necrosis, and a few CPC. The highest rate of apoptosis was discovered in the synovial effusions of patients with RA, the lowest in those with OA, while the rate of CPC among the inflammatory joint diseases was the lowest in RA. In RA the current disease activity correlated with the incidence of apoptotic cells and CPC, while the clinical stage was related only to the CPC rate. These data suggest that in RA, despite exposure to the anti-apoptotic signals, apoptosis of the synovial effusion PMN is maintained at a significantly higher level than in non-rheumatoid arthropathies, both inflammatory (SSA) and degenerative (OA), providing elimination of the neutrophils accumulating in the joint cavity and thus stimulating resolution of the joint inflammation.

OBJECTIVE: To determine in situ using TEM the balance of apoptosis and necrosis in the articular cartilage of patients with inflammatory (rheumatoid arthritis and seronegative spondyloarthritis) and degenerative (osteoarthritis) joint diseases and to establish possible correlation between the cell death rate and the matrix vesicles formation. METHODS: Cartilage samples of the knee joint were obtained from patients with rheumatoid arthritis (RA, 18 cases), osteoarthritis (OA, 22 cases), Reiter's disease (RD, 9 cases), peripheral form of the ankylosing spondyloarthritis (AS, 6 cases) and psoriatic arthritis (PA, 6 cases) during arthroscopy or knee surgery. Normal samples taken from autopsy cases without a history of joint diseases were used as control. Samples were processed for TEM with subsequent semi-quantitative estimation of the cell death rate in the superficial, middle and deep zone of non-calcified articular cartilage, and computer-aided ultramorphometric evaluation of the matrix vesicles of different types. RESULTS: Both apoptotic and necrotic cell death could be identified in the cartilage of patients with inflammatory joint diseases, including seronegative spondyloarthritides and degenerative arthropathies. Apoptosis dominated over necrosis in all examined arthritides, including RA patients in which necrosis of the chondrocyte was the most frequent among arthropathies, while the highest apoptotic cell death rate was discovered in OA in which it correlated with the volume and numeric density of the matrix vesicles. These data provide evidence that apoptosis may contribute to the cartilage breakdown not only in RA and OA but also in the seronegative spondyloarthritides, which had a significantly higher apoptotic rate than the normal cartilage.

Background: Postoperative urinary retention is a commonly encountered problem after anal surgery particularly under spinal anesthesia. Bethanchol chloride, a muscarinic cholinergic receptor agonist was used to determine whether it could prevent this problem.
Methods: One hundred six patients with mean age of 37+ 9 who underwent anal surgery under spinal anesthesia from January to August 2007 were included in this nonblinded randomized prospective experimental study. Forty- six patients were given bethanechol chloride 25mg/tab 1 hour post- op then another dose after 4-6 hours. Those with the urge to void but unable to do so within the hour or had hypogastric pain (VAS > 8) were immediately catheterized and the amount drain recorded.
Conclusion: Although bethanechol chloride did not completely prevent the development of postoperative urinary retention, it use was associated with reduced need for the catheterization.

OBJECTIVE: The study aimed to evaluate efficacy of tiotropium as add-on therapy on top of standard regimens for uncontrolled asthma, specifically in terms of FEV1, morning and evening PEF, reduction in exacerbations, rescue medication use, and quality of life improvement.
METHODS: A search was done for eligible trials after which validity screen and data extraction was performed. Results were presented as mean differences, standard errors, and 95% confidence intervals, and graphically as forest plots. Estimates were pooled using the random effects model with I2 and Chi2 tests used to assess heterogeneity. Adverse events were reported as dichotomous variables.
RESULTS: Four studies were included totaling 1617 participants. The tiotropium group had statistically significant improvement in FEV1 (95% Cl, 0.14 [0.09, 0.19], p<0.00001), morning (95% Cl, 20.03 [11.71, 28.35], p<0.00001) with trend towards benefit in reduction of rescue medications (95% Cl, 0.12 [-0.17,0.4],p=0.42) and quality of life improvements (95% Cl, 0.1 [-0.05,0.25], p=0.20). Homogeneity (I2= 0%, Chi2= 0.47-3.22) was found across studies.
CONCLUSION: Tiotropium is associated with significant improvement in pulmonary function among patients with uncontrolled asthma, with possible benefit in reduction of rescue medications and quality of life improvement.

OBJECTIVE: To evaluate the safety, effectiveness and health-related quality of life (HRQoL) parameters of A1chieve study participants in the Philippine cohort, who were treated with BIAsp 30.
METHODOLOGY: A1chieve is a non-interventional, six-month, observational study of 66,726 people with type 2 diabetes mellitus (T2DM), including both insulin users and non-insulin users, started on insulin detemir, insulin aspart, or BIAsp 30 in 28 countries across four continents. The present study evaluates the safety, effectiveness and HRQoL in 1,252 subjects from the Philippine cohort of the A1chieve study who were treated with BIAsp 30.
RESULTS: At baseline, the mean age, duration of diabetes and mean BMI were found to be 55.5±11.7 years, 7.2 ± 5.6 years and 25.4 ± 5.3 kg/m2, respectively. Seventy-eight percent (78%) of subjects were insulin naïve and 22% were prior insulin users. At baseline, glycemic control was poor (HbA1c = 9.9%) in the entire cohort. Overall there was a 2.7% reduction in mean HbA1c and 44.2% subjects achieved the HbA1c target of <7.0%, after 24 weeks of therapy with BIAsp 30. There were significant reductions in total cholesterol, LDL-cholesterol, triglycerides and systolic blood pressure after 24 weeks of therapy with BIAsp 30. There was no increase in the incidence of hypoglycemia among insulin-naïve subjects, while there was a marked reduction in hypoglycemia (4.93 to 2.53 events/person-year) among prior insulin users at 24 weeks.
CONCLUSION: BIAsp 30 is safe and efficacious for initiating and intensifying insulin therapy for Filipino T2DM patients.

OBJECTIV E To study composition an d content changes of volatile components during the bleaching process of Atractylodis macrocephala with the water of washing rice. METHODS The raw products of A. macrocephala and bleached products of 5 different bleaching stages were prepared (in the first and second stages ,raw products were bleached with 9-fold volumn of the water of washing rice for 12 h and 24 h,respectively;in the third ,fourth and fifth stages ,the raw products were firstly bleached with 9-fold volumn of the water of washing rice for 24 h,and then bleached with 9-fold volumn of clean water for 12,24 and 48 h,respectively);the bleaching temperature was set at 26 ℃. The volatile components of raw products of A. macrocephala and its bleached products of 5 different bleaching stages were qualitatively analyzed by using headspace gas chromatography-mass spectrometry. The relative percentage of each component was calculated by peak area normalization method. RESULTS A total of 49 volatile components were identified from raw products of A. macrocephala and its bleached products of 5 different bleaching stages,including 20 common volatile components such as terpinolene ,cyperene and atractylon ,etc. Among them ,33,31,28, 30,28 and 29 volatile components were identified from the raw products of A. macrocephala and the bleached products of the first to fifth stages ,the relative percentages of which were 66.218% ,64.711% ,79.410% ,65.419% ,67.101% ,66.818% , respectively;among them ,the relative percentage of atractylon in bleached products was the highest in the fourth stage (41.206%),but was the lowest in the third stage (35.926%). Compared with the raw product ,16 volatile components such as pethylbrene and β-vetivenen were added in the bleaching process ,while 8 volatile components such as ethyl palmitate and β-maaliene were not detected. However ,5 volatile components including 11-rotundene and (-)-valeranone in the bleaching process showed a trend of disappearance-emergence and disappearance-emergence-disappearance. CONCLUSIONS In the third stage,the total relative percentage of each volatile component and the relative percentage of representative dry component as , atractylone are the lowest in bleached products of A. ; macrocephala,i.e. the bleaching technology of relieving the dry property of A. macrocephala e with the water of washing rice is bleaching with 9-fold volumn of the water of washing rice for 24 h,and then bleaching with 9-fold volumn of clean water for 12 h.

Objective: To study the prevalence and characteristics of overweight and obesity among Chinese children aged 0-5 years, in 2010-2013. Methods: Data was from the'China Nutrition and Health Surveillance-0-5-Years-Old Children and Lactating Women'project in 2013. Stratified multistage cluster sampling method was used to select 55 districts/counties from 30 provinces (autonomous regions, municipalities) with the sample size of children as 32 862. Definition of overweight and obesity were according to both the WHO 2006 growth standard in children less than 5-year-old and the WHO 2007 growth reference in children of 5-years-old. Results: were calculated by complex weight based on national census from the National Bureau of Statistics in 2010. Results The overall prevalence of overweight was 8.4% among the 0-5-year-old in 2013, with 9.4% in boys and 7.2% in girls. Both of the rates from urban and rural areas were the same, as 8.4%. The prevalence rates of overweight in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups appeared as 13.0%, 11.1%, 8.3%, 6.0%, 4.8%, 3.9% and 15.9%, respectively. The rates of overweight in low, medium and high income families were 8.0%, 8.8% and 8.9%, respectively. The prevalence of obesity was 3.1% among the 0-5-year-old, with 3.6% in boys and 2.5% in girls. There was no significant difference seen in urban (3.3%) and rural areas (2.9%). The prevalence rates for obesity in the 0-, 6-, 12-, 24-, 36-, 48- and 60-71 months age groups were 5.8%, 3.8%, 2.5%, 1.6%, 1.2%, 1.3% and 7.8%, respectively. The rates of obesity in low, medium and high income families were 2.8%, 3.3% and 3.5%, respectively. Conclusion: The prevalence rates of both overweight and obesity were increasing among the 0-5-year-olds in China, suggesting that it is necessary to timely conduct the surveillance and intervention programs on overweight and obesity in this target population.

The genus Rhodococcus is of considerable interest in recent years, stemming from their diverse applications in biodegradation, bioremediation, biotransformation and biosurfactant. Using Nocardia/Rhodococcus-Escherichia coli shuttle plasmid pNV18.1 as the backbone vector, we tested the driven efficiency of promoters Ptac and PlacZ of E. coli and Pami-1/Pami-2 of R. ruber in host R. rhodochrous ATCC 33278 by overexpression of nitrile hydratase. Results showed that the specific activity of nitrile hydratase per dry cell weight in engineered Rhodococcus strains driven by Ptac, Pami-1, Pami-2 and PlacZ was 7.5, 6.3, 5.3 and 1.8 times of that in the wild, respectively. It indicated that these promoters could be well recognized by RNA polymerase of Rhodococcus. We further expressed the beta-galactosidase reporter gene (lacZ) in R. ruber driven by promoter PlacZ. Results indicated that lacZ was an appropriate reporter gene for genetic or metabolic engineering research of Rhodococcus.
