ABSTRACT
Objective:To explore the distribution characteristics of traditional Chinese medicine （TCM） syndromes of abnormal uterine bleeding associated with ovulatory dysfunction （AUB-O）. Method:A clinical and epidemiological investigation was conducted in 6 688 patients with AUB-O from the provincial， municipal， and county/district hospitals in 29 provinces， autonomous regions， and municipalities across China to identify the distribution characteristics of their TCM syndromes. Result:The AUB-O patients nationwide were mainly differentiated into the kidney Qi deficiency syndrome （17.34%）， the spleen Qi deficiency syndrome （13.25%）， the Qi and blood deficiency syndrome （12.62%）， the Qi deficiency and blood stasis syndrome （8.45%）， and the kidney Yin deficiency syndrome （6.88%）. AUB-O resulted from Qi deficiency， Yin deficiency， and blood deficiency， often involving the kidney， spleen and liver. The analysis of the regional distribution of TCM syndromes in AUB-O patients revealed that kidney Qi deficiency， spleen Qi deficiency， and Qi and blood deficiency were the shared syndromes. However， due to regional discrepancy， the TCM syndrome varied widely from one geographic region to another. The kidney Qi deficiency syndrome was more frequently seen in North China， Northwest China， Southwest China， and East China， but less frequently in central China， Northeast China， and South China. The spleen Qi deficiency syndrome occurred most frequently in central China， while the East China had the highest frequency of Qi and blood deficiency syndrome. The spleen and kidney deficiency syndrome was mostly present in central China， North China， and Southwest China， the Qi deficiency （kidney deficiency） and blood stasis syndrome in Northwest China， South China， and North China， the kidney Yin deficiency syndrome in East China， Northwest China， and Northeast China， the deficiency-heat syndrome in Southwest China and East China， the kidney Yang deficiency syndrome in South China， the liver depression and blood heat syndrome in Northeast China， and the liver depression and spleen deficiency syndrome in central China. The diagnostic criteria for the kidney Qi deficiency， spleen Qi deficiency， Qi and blood deficiency， Qi deficiency and blood stasis， and kidney Yin deficiency syndromes were not significantly different from the previous ones. The distinctive symptoms for the kidney Qi deficiency syndrome were irregular vaginal bleeding， heavy menstrual flow， or shortened menstrual cycle， back soreness and pain， and forgetfulness， while those for the spleen Qi deficiency syndrome mainly included the shortened menstrual cycle， mental fatigue， lack of strength， poor appetite， loose stool， and white tongue coating. The Qi and blood deficiency syndrome were mainly manifested as the shortness of breath， laziness to speak， pale complexion， dizziness， and palpitation. The Qi deficiency and blood stasis syndrome were mainly judged by the scanty menstrual flow frequently or occasionally accompanied by blood clots， mental fatigue， lack of strength， and dark purple tongue. The ovulatory bleeding， dizziness， tinnitus， vexing heat in chest， palms and soles， and night sweat were the characteristic signs for the kidney Yin deficiency syndrome. Conclusion:There exist certain rules in the geographical distribution of TCM syndromes of AUB-O patients， which has provided a reference for the clinical treatment of AUB-O in accordance with the local conditions.

ABSTRACT
The plants of Bletilla are one of the groups in Orchidaceae with the highest economic value. As the traditional Chinese medicinal material, Bletillae Rhizoma exhibits excellent efficacy in hemostatic, antibiosis, detumescent, anticancer activities and regenerating tissue to heal wound, which has great development potential. However, Bletillae Rhizoma is mainly collected from wild resources. At present, the quantity of wild resources of Bletilla plants has sharply decreased and is far from meeting the needs. Resource appraisal and breeding and cultivation of excellent germplasms of Bletilla plants are important for scientific utilization of the resources of the genus. This paper reviewed the following researches of Chinese Bletilla resources: species and distribution, genetic diversity, active ingredient evaluation, breeding, as well as seeding production and cultivation techniques. Suggestions were also provided in further researches on the resources evaluation, sustainable development and efficient utilization of Chinese Bletilla plants.

ABSTRACT
OBJECTIVE To observe the effects of glycogen synthase 3β (GSK-3β) in the regula-tion of NLRP3 inflammasome activation after acute myocardial infarction (MI) in Sprague Dawley(SD) rats. METHODS Ligation of the left anterior descending (LAD) in SD rats was used to establish an acute myocardial infarction model. SD rats were randomly divided into 3 groups (n=10, each group):sham group,MI group,and MI+SB group:the GSK-3β inhibitor(SB216763)was given 1 h by intrave-nous injection(0.6 mg·kg-1·d-1)before surgery.The serum and heart tissue were collected to measure lactate dehydrogenase (LDH) and IL-1β content and mRNA and protein levels of NLRP3, ASC, Cas-pase-1,IL-1β and GSK-3β after 2 days and 7 days operation,respectively.RESULTS The serum levels of LDH and IL-1β in the MI group were significantly higher than those in the sham group(P<0.01),and the MI+SB group was obviously lower than the MI group(P<0.01).In addition,mRNA and protein levels of NNLRP3, ASC, Caspase-1, IL-1β and GSK-3β expressions in MI group were clearly increased (P<0.01) compared with those in sham group.These indicators were significantly decreased in SB+MI group (P<0.01). Interestingly, the indicators were all higher at 7 days than 2 days. CONCLUSION GSK-3β inhibition induces cardioprotection via attenuating the activation of NLRP3 inflammasome after the acute myocardial infarction in rats.
ABSTRACT
PURPOSE: Previous western studies have found Caucasians with skin cancer, either melanoma or nonmelanoma skin cancer (NMSC), have an elevated risk of second primary cancer. Our objective was to assess the risk of second primary cancer in Taiwanese with NMSC. MATERIALS AND METHODS: By using data from Taiwan's National Health Insurance Research Database, we conducted a population-based cohort study to assess the risk of incident second primary cancer in Taiwanese affected by NMSC. RESULTS: We identified 505 subjects with NMSC and 2,020 matched controls. After adjustment for potential confounders including age, sex, urbanization, and Charlson Comorbidity Index, people who had NMSC had a 1.43-fold (95% confidence interval [CI], 1.05 to 1.96) risk for the development of second primary cancer as comparedwith control group. Menwith NMSC had a 2.99-fold (95% CI, 1.00 to 9.10) risk for second primary cancer involving the lip, oral cavity, and pharynx and a 3.51-fold (95% CI, 1.21 to 10.17) risk for second primary cancer involving the genitourinary organs when compared to the control group. By contrast, women with NMSC did not have an increased risk of second primary cancer. CONCLUSION: This study revealed Asians with NMSC have an increased risk of second primary cancer. Our findings can be a useful reference for health care for people diagnosed with NMSC.

To optimize the immunization strategy against HIV-1, a DNA vaccine was combined with a recombinant vaccinia virus (rTV) vaccine and a protein vaccine. Immune responses against HIV-1 were detected in 30 female guinea pigs divided into six groups. Three groups of guinea pigs were primed with HIV-1 DNA vaccine three times, boosted with rTV at week 14, and then boosted with gp140 protein at intervals of 4, 8 or 12 weeks. Simultaneously, the other three groups of animals were primed with rTV vaccine once, and then boosted with gp140 after 4, 8 or 12 weeks. The HIV-1 specific binding antibody and neutralizing antibody, in addition to the relative affinity of these antibodies, were detected at different time points after the final administration of vaccine in each group. The DNA-rTV-gp140 immune regimen induced higher titers and affinity levels of HIV-1 gp120/gp140 antibodies and stronger V1V2-gp70 antibodies than the rTV-gp140 regimen. In the guinea pigs that underwent the DNA-rTV-gp140 regimen, the highest V1V2-gp70 antibody was induced in the 12-week-interval group. However, the avidity of antibodies was improved in the 4-week-interval group. Using the rTV-gp140 immunization strategy, guinea pigs boosted at 8 or 12 weeks after rTV priming elicited stronger humoral responses than those boosted at 4 weeks after priming. In conclusion, this study shows that the immunization strategy of HIV-1 DNA vaccine priming, followed by rTV and protein vaccine boosting, could strengthen the humoral response against HIV-1. Longer intervals were better to induce V1V2-gp70-specific antibodies, while shorter intervals were more beneficial to enhance the avidity of antibodies.

<p><b>OBJECTIVE</b>To observe the relationship between serum and monocyte-derived-macrophages secreted adipocyte fatty acid binding protein (A-FABP), adiponectin (or A-FABP/adiponectin ratio) and coronary artery disease.</p><p><b>METHODS</b>Three hundred and forty subjects underwent coronary angiography (CAG) were classified into CAD group (n = 211) and non-CAD group (n = 129) according to the CAG results. The severity of coronary artery stenosis was assessed by the numbers of involved coronary artery branches and the sum of the Gensini scores. Fasting venous blood was collected from all subjects and peripheral monocytes were isolated from 20 subjects (10 selected from each group with age-, gender-, and BMI-matched). Peripheral blood monocytes were obtained and stimulated into macrophages with PMA, cell culture supernatant was collected. The concentration of serum/supernatant A-FABP and adiponectin levels were assayed by enzyme-linked immunosorbent assays.</p><p><b>RESULTS</b>(1) A-FABP levels tended to be higher in CAD patients compared to non-CAD subjects [18.3(13.2, 22.8) µg/L vs. 16.4(13.5, 20.4) µg/L, P = 0.088]. The concentration of adiponectin in CAD group was significantly lower than those in non-CAD group [13.9 (9.8, 17.1) mg/L vs. 19.7 (14.5, 27.6) mg/L, P < 0.05]. (2) The A-FABP levels increased and the adiponectin levels decreased as the number of stenotic vessels increased. Gensini scores were positively correlated with serum A-FABP (r = 0.120, P = 0.043) and inversely correlated with adiponectin (r = -0.405, P = 0.007). (3) The difference in A-FABP/adiponectin ratio was more prominent between subjects with CAD and subjects without CAD [(1.51 ± 0.79) µg/mg vs. (0.89 ± 0.30) µg/mg, P < 0.01] and there was a stronger positive correlation of Gensini score to A-FABP/adiponectin ratio(r = 0.531, P = 0.000). (4) Monocyte-derived-macrophages from patients with CAD had higher A-FABP/adiponectin ratio than that in patients without CAD [(0.51 ± 0.19) µg/mg vs. (0.36 ± 0.11) µg/mg, P < 0.05].</p><p><b>CONCLUSIONS</b>Increased levels of serum A-FABP and reduced levels of adiponectin in CAD patients serves as a novel biomarker for the severity of the coronary stenosis. A-FABP/adiponectin ratio is superior to A-FABP or adiponectin alone on predicting CAD risks.</p>
