[Purpose] We studied the pathophysiology of hot flush and cold feet.[Methods] By using an infrared thermometer, we measured the surface temperature of 98 female patients. We classified the patients into 4 groups : Group A patients without hot flushes or cold feet ; Group B patients with hot flushes but without cold feet ; Group C, patients without hot flushes but with cold feet ; and Group D patients with both hot flushes and cold feet. We measured the surface temperature of their tongues, upper abdomen, lower abdomen, and soles.[Results] The tongue temperature in Group B was significantly higher than that in Group A. The difference in the temperatures between the tongue and upper abdomen in Group B was also significantly greater than that in group A. Groups C and D, on the other hand, showed similar surface temperatures. Then, we examined the relationship between tongue temperatures, and the difference in the temperatures between the tongue and sole (Diff T-S) by using a correlation coefficient test : a significant correlation (r=0.77) was observed in Group C but not in Group D. Next, the patients in Group D were divided into 3 subgroups on the basis of their Diff T-S ; we found that these subgroups were characterized by the constitutionally ordinary symptoms (COS) of “yin and yang” and “deficiency and excess.”[Discussion] The occurrence of hot flush with cold feet was shown to depend on the slope of the body temperature, which was influenced by COS.[Conclusion] The occurrence of hot flush is associated with COS.

Calcium intake may play an important role on bone health. The recent national nutritional survey in Japan revealed the gradual decrease in calcium intake to around 480 mg/day. In addition, the patients with low level of vitamin D become too large in proportion. The present perspective proposes to increase calcium intake in Asian population.

BACKGROUND AND OBJECTIVEIt has been proven that close relation was existed between XPD polymorphism G312A and lung cancer risk. However, some of the results are not consistent. The aim of this study is to explore the impact of DNA repair gene XPD polymorphism G312A on lung cancer risk.

METHODSThe literatures eligible from PUBMED, EMBASE, CNKI and WANGFANG database were enrolled in the meta-analysis. Heterogeneity among combined studies was assessed. The pooled OR and 95%CI were calculated. The sensitivity analysis and the publication bias were evaluated by RevMan 5.0 and STATA 11.0.

RESULTSThere were 6554 cases and 8322 controls from 18 studies included in the meta-analysis. In total, individuals with 312A allele and 312AA genotype showed increased lung cancer risk (A vs. G: OR = 1.06, 95% CI: 1.00-1.12; AA vs. AG+GG: OR = 1.20, 95% CI: 1.06-1.36; AA vs. GG: OR = 1.19, 95% CI: 1.04-1.36). In Asians, individuals with 312AA genotype showed 6.15 fold and 6.20 fold increased lung cancer risk in recessive genetic model and homogenous contrast respectively (AA vs. AG+GG: OR = 7.15, 95% CI: 1.90-26.94; AA vs. GG: OR = 7.20, 95% CI: 1.91-27.15). In Caucasians, individuals with 312AA genotype showed a 15% increased lung cancer risk (OR = 1.15, 95% CI: 1.01-1.31).

CONCLUSIONXPD 312A allele is risk allele for lung cancer. Individuals with AA genotype have higher risk of lung cancer, especially in Asians.

Objective: Serum 25−hydroxyvitamin D [25(OH)D] is a vitamin D metabolite and a good indicator of vitamin D nutritional status. Low 25(OH)D levels accelerate age−related bone loss in women. The aim of this study was to assess 25(OH)D levels using population−based samples from women in a community in Japan. Subjects and Methods: Of all 187 adult women living on a solitary island (Niigata, Japan), 150 (80.2%) were enrolled in a cross−sectional study in early June 1998. After excluding 6 subjects who were undergoing treatment for osteoporosis, 144 female subjects were analyzed. Serum 25(OH)D2 and 25(OH)D3 were determined by high−performance liquid chromatography. The sum of 25(OH)D2 and 25(OH)D3 was calculated, yielding 25(OH)D, for which a concentration of less than 30 nmol/L was defined as vitamin D insufficiency. Demographic data such as age, height, weight, and body mass index (BMI) were also recorded. Results: The average age of the subjects was 61.3 years (SD 12.8), ranging from 21 to 87. The average concentrations of 25(OH)D2 and 25(OH)D3 were 0.5nmol/L (SD 3.2) and 64.6nmol/L (SD 17.6), respectively. The number of subjects with 25(OH)D concentration less than 30nmol/L was 4 of 149(2.7%). Serum 25(OH)D concentrations were not significantly correlated with age (r=−0.065, p=0.441) or BMI (r=0.086, p=0.310). Conclusion: The present population−based study confirms adequate levels of 25(OH)D and low prevalence of vitamin D insufficiency in Japanese women. Further research should be directed toward clarifying which dietary factors determine vitamin D nutrition.

BACKGROUND/AIMS: Studies on the micronutrient status of Asian patients with inflammatory bowel disease (IBD) are scarce. We evaluated the prevalence of micronutrient deficiency and verified the risk factors for micronutrient deficiency in Korean patients with IBD. METHODS: We measured the serum levels of 25-hydroxyvitamin D3 [25-(OH)D], zinc, and selenium to analyze the clinical risk factors for micronutrient levels below the reference values. In addition, we compared the 25-(OH)D levels of patients with IBD to those of age- and sex-matched healthy controls. RESULTS: Among the 83 patients, 74 (89.2%) had suboptimal serum 25-(OH)D levels. The mean plasma 25-(OH)D level in patients with IBD was significantly reduced compared to that of the healthy controls (12.3±6.2 ng/mL vs 20.0±6.7 ng/mL; p<0.001). The proportions of patients with lower serum zinc and selenium levels were 39.0% and 30.9%, respectively. Female sex (p=0.012) and Crohn’s disease (p=0.012) were associated with vitamin D deficiency. Patients younger than 40 years were at increased risk for zinc deficiency (p=0.045). Female sex (p=0.015) and low serum albumin level (<3.3 g/dL) (p=0.047) were risk factors for selenium deficiency. CONCLUSIONS: Many Korean patients with IBD have vitamin D, zinc, and selenium deficiencies, suggesting the necessity for monitoring levels of these micronutrients.

OBJECTIVE: There has been no prospective study that examined intramuscular injection of high-dose vitamin D in Korean adults. The aim of this study was to assess the efficacy and safety of high-dose vitamin D3 after intramuscular injection in Korean adults with vitamin D deficiency. METHODS: This study was a 24-week, prospective, multicenter, randomized, double-blind, placebo-controlled trial. A total of 84 subjects ≥19 and <65 years of age were randomly allocated to either the vitamin D3 or placebo group in a 2:1 ratio. After randomization, a single injection of plain vitamin D3 200,000 IU or placebo was intramuscularly administered. If serum 25-hydroxyvitamin D (25[OH]D) concentrations were <30 ng/mL on week 12 or thereafter, a repeat injection was administered. RESULTS: After a single intramuscular injection of vitamin D3 to adults with vitamin D deficiency, the proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 12 weeks was 46.4% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). The proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 24 weeks was 73.2% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). Mean change in serum 25(OH)D concentrations at weeks 12 and 24 after vitamin D3 injection was 12.8 ± 8.1 and 21.5 ± 8.1 ng/mL, respectively, in the vitamin D3 group, with no significant changes in the placebo group. Serum parathyroid hormone concentrations showed a significant decrease in the vitamin D3 group but no change in the placebo group. CONCLUSION: Intramuscular injection of vitamin D3 200,000 IU was superior to placebo in terms of its impact on serum 25(OH)D concentrations, and is considered to be safe and effective in Korean adults with vitamin D deficiency.

OBJECTIVETo investigate the association between vitamin D deficiency and risk of gestational diabetes mellitus (GDM) in pregnant Chinese women.

METHODSA nested case-control study was conducted. Clinical and biochemical data were analyzed for 200 subjects with GDM and 200 subjects with normal glucose tolerance (NGT).

RESULTSThe median (interquartile range) serum 25-hydroxyvitamin D (25OHD) levels were 22.39 (17.67, 29.38) and 25.86 (19.09, 34.88) nmol/L in the GDM and NGT groups, respectively. Rates of 25OHD deficiency or insufficiency were significantly higher in the GDM group than in the NGT group. Subjects with 25OHD levels <25 nmol/L had a 1.8-fold higher risk of GDM compared with subjects with higher vitamin D levels. In the GDM group, serum 25OHD was independently associated with HbA1c and insulin resistance after adjusting for confounding factors. In the NGT group, serum 25OHD was independently associated with fasting plasma glucose and systolic blood pressure after adjusting for maternal age and other confounding factors.

CONCLUSION25OHD insufficiency is very common in Chinese women. Low 25OHD status may be associated with insulin resistance and act as a risk factor for GDM.

OBJECTIVE: The aim of the present study was to perform a subgroup analysis of data from a phase II global, multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of bitopertin, a glycine reuptake inhibitor that activates N-methyl-D-aspartate receptors by increasing the concentration of glycine in the synaptic cleft, in Japanese and non-Japanese patients with schizophrenia and predominant negative symptoms. METHODS: Patients with schizophrenia and predominant negative symptoms on one or two antipsychotic drugs, including atypical antipsychotic drugs (olanzapine, risperidone, quetiapine, aripiprazole, and paliperidone) as the primary treatment, received bitopertin (10, 30, or 60 mg/day) or placebo once daily for 8 weeks as an add-on treatment. Efficacy was assessed using the Positive and Negative Syndrome Scale (PANSS) negative symptom factor score (NSFS). RESULTS: The efficacy of bitopertin (10 mg and 30 mg) was similar between Japanese and non-Japanese patients. In the bitopertin 60-mg group, no difference from the placebo group was observed in Japanese or non-Japanese patients. The response to placebo was lower in Japanese patients, and there was a trend towards a greater difference in the change in PANSS NSFS between the placebo group and the 10-mg and 30-mg groups among Japanese patients. The safety profile of bitopertin was favorable in Japanese and non-Japanese patients. CONCLUSION: According to this subgroup analysis from a global phase II study of bitopertin, there was no difference in terms of efficacy and safety between Japanese and non-Japanese patients.

In order to analyze the genotype of RhD-negative blood donors with immune antibodies in Harbin, the voluntary blood donors from 1 April 2008 to 30 september 2011 were detected serologically to determine the RhD-negative donors. The blood donors confirmed to be RhD negative were detected to screen the immune antibodies, the samples with immune antibodies were analyzed by PCR-SSP and DNA sequencing to detect RhD genotype. The results showed that the 12 cases of the immune antibodies (0.95%) were screened out from 1265 cases of RhD-negative donors, among which 9 cases showed anti-D-antibody, 3 cases showed anti-(D+C) antibody; 10 cases were RhD-negative, 2 cases were RHD 711D(el)C. It is concluded that RhD negative and RHD 711D(el)C are easy to be immunized to produce the immune antibodies; RhD-negative population, especially women should be highly aware of avoiding mis-transfusion of RhD-positive blood, and also avoiding multiple pregnancies resulting in newborn's hemolytic disease.

OBJECTIVES: The aim of this study was to examine the efficacy, safety, and adherence of ibandronate (IBN) treatment with or without vitamin D supplementation for 3 years in Japanese women with postmenopausal osteoporosis. METHODS: This prospective investigation included 27 patients treated with IBN alone (monotherapy group) and 29 patients receiving IBN and alfacalcidol (ALF) (combination group). Bone metabolism and bone mineral density (BMD) were measured before and at 18, 24, 30, and 36 months of therapy. Treatment discontinuation and fracture occurrence were assessed as well. RESULTS: Lumbar 1–4 BMD (L-BMD) was significantly increased in the monotherapy and combination groups by 3.9% and 7.2%, respectively, at 36 months, with significant gains in total hip BMD (H-BMD) of 3.7% and 4.9%, respectively. There were significant differences in L-BMD improvement between the groups at 18, 24, and 30 months (P < 0.05) and at 36 months (P < 0.01). Compared with pretreatment levels, the percentage changes of L-BMD and H-BMD were significant at all time points in the combination group and at all points apart from L-BMD at 36 months in the monotherapy group. In the monotherapy group, 14 patients dropped out during 3 years and 2 vertebral fractures occurred during the first year. In the combination group, 16 cases dropped out during 3 years and 1 nonvertebral fracture was noted during the first year. CONCLUSIONS: Our findings suggest that combination therapy of IBN and vitamin D is superior to monotherapy with regard to L-BMD improvements for 3 years, with both groups showing comparable safety and adherence to treatment.
