Abstract
OBJECTIVE To evaluate the effectiveness and safety of Zhenqi Buxue Oral Liquid (ZQ), progesterone capsules, and their combination in treating oligomenorrhea and hypomenorrhea with qi-blood and Kidney (Shen) essence deficiency. METHODS This was a prospective, randomized, multi-center controlled trial between June 2022 to December 2022. Ninety-six oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency were randomly assigned to receive ZQ (ZQ group, 29 cases), progesterone capsules (PG group, 32 cases), or the combined Chinese and Western medicine (COM group, 31 cases) at a ratio of 1:1:1. Patients in the ZQ or PG group took daily 10 mL twice a day of ZQ or 200 mg once a day of progesterone capsules for 10 consecutive days on day 15 of the menstrual cycle respectively, and patients in the COM group received the same ZQ combined with progesterone capsules. The treatment course lasted for 3 months and follow-up was performed at 1 and 3 months after the end of treatment. Primary endpoint was the menstrual Traditional Chinese Medicine Syndrome Scale (TCMSS) scores. Secondary endpoints included pictorial blood loss assessment chart (PBAC) scores, clinical efficacy rate, 36-item Short Form Health Survey (SF-36) scores, sex hormones and thickness of endometrium. Adverse events (AEs) were recorded. RESULTS TCMSS scores after 1- and 3-month treatment in all groups were significantly lower than those at baseline (P<0.05). Only TCMSS scores after 3-month treatment in the ZQ and COM groups continuously decreased compared with those after 1-month treatment in the same group (P<0.01). TCMSS scores after 3-month treatment in the ZQ and COM groups were significantly lower than those in the PG group (P<0.05, P<0.01). Compared with baseline, PBAC scores in the ZQ and COM groups after 3 months of treatment were also significantly higher (both P<0.01). The total effective rates of TCM syndrome of 3-month treatment were significantly improved in all groups compared with that after 1 month of treatment (P<0.05). The total effective rate of the COM group was the highest in the 3rd month of treatment and significantly higher than that of PG group alone (P<0.05). Compared with baseline, only the SF-36 scores of COM group were significantly improved after 3 months of treatment (P<0.05). No serious adverse reactions were observed after treatment. CONCLUSIONS The combination of ZQ and PG, or ZQ only had better effects on reducing TCMSS scores compared with PG, and COM showed the higher total effective rate compared with monotherapy. Besides, COM could effectively improve menstrual blood loss and quality of life. ZQ combined with PG may be an effective and safe option for oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency.

Abstract
Ultrafast control of material physical properties represents a rapidly developing field in condensed matter physics. Yet, accessing the long-lived photoinduced electronic states is still in its early stages, especially with respect to an insulator to metal phase transition. Here, by combining transport measurement with ultrashort photoexcitation and coherent phonon spectroscopy, we report on photoinduced multistage phase transitions in Ta2NiSe5. Upon excitation by weak pulse intensity, the system is triggered to a short-lived state accompanied by a structural change. Further increasing the excitation intensity beyond a threshold, a photoinduced steady new state is achieved where the resistivity drops by more than four orders at temperature 50 K. This new state is thermally stable up to at least 350 K and exhibits a lattice structure different from any of the thermally accessible equilibrium states. Transmission electron microscopy reveals an in-chain Ta atom displacement in the photoinduced new structure phase. We also found that nano-sheet samples with the thickness less than the optical penetration depth are required for attaining a complete transition.

Abstract
Objective: To analysis the clinical characteristics of"recurrence"RNA positive patients with Coronavirus disease 2019 (COVID-19) and compared with those without"recurrence". Methods: 98 patients with COVID-19 in Wuhan Jinyintan Hospital and designated treatment hospitals in Quanzhou were included in this study from February 2020 to April 2020. There were 55 males and 43 females, aged from15 to 83 years, with a median age of 57.5 years, in which 20 cases were complicated with basic diseases. 15 of these patients had been diagnosed and hospitalized had been found as"recurrence"2019-nCoV RNA positive after discharge while the other 83 cases were all negative. The clinical classification of all patients was common type. Clinical data of the COVID-19 RNA"recurrence"patients were collected, and general situations, symptoms, laboratory examinations and CT images were also observed and analyzed. The patients were divided into 2019-nCoV"recurrent"group and 2019-nCoV"non-recurrent"group. There are 10 males and 5 females in 2019-nCoV"recurrent"group while 45 males and 38 females in"non-recurrent"group (χ²=0.800,P=0.371). The age of 2019-nCoV"recurrent"group (57±21) was higher than that of"non-recurrent"group(53±17). 8 of 15 the COVID-19"recurrent"group patients and 12 of 83"non-recurrent"patients have basic diseases. IgG and IgM of 2019-nCoV, IL-6, procalcitonin, ESR, CRP, BNP and other serum biochemical index levels were measured and compared between groups. Results: (1) The proportion of patients with common type of COVID-19 was 15.3% during 2-week medical observation after discharge. (2) All of the 2019-nCoV"recurrent"patients were hospitalized due to COVID-19 RNA positive, when they were quarantined after discharged from hospital. All the patients with mild symptoms which were clarified as common type, including 5 cases of fever, 6 cases of cough, 5 cases of expectoration, and 2 cases of slight shortness of breath. The time of symptoms appeared on (5.73±2.82) days after discharge. (3) The serum procalcitonin of all 2019-nCoV"recurrent"group patients were normal(all<0.05 ng/ml). The BNP of"recurrent"group (151±171) ng/L, was higher than that of"non-recurrent"group (63±78) ng/L (t = 3.207, P = 0.000). There was no significant difference in laboratory tests like leukocyte [(6.17±2.4) and (6.04±2.41)×109/L], lymphocyte[(1.59±0.52) and (1.32±0.64)×109/L], CRP [(12.54±28.20) and (21.74±25.63)mg/L], ESR [(31.07±28.72) and (34.10±22.16)mm/1 h], AST [(24.73±9.15) and (30.24±23.20)U/L], ALT [(22.60±12.82) and (36.47±34.12)U/L), LDH [(268±208) and (270±164)U/L], D-dimer [(0.60±0.50) and (0.84±0.98)μg/L], ferritin [(294±195) and (395±319)μg/L], IL-6 [(9.17±6.42) and (14.28±17.74)ng/L] and BUN (5.77±2.66) and (4.74±2.81)U/L] between"recurrent"and"non-recurrent"groups (all P>0.05). (4) In"recurrent"group, ground glass, exudative or solid lesions could be found in most of the chest CT performed on re-admission. Meanwhile, fibrosis lesion was relatively rare. (5) There were no secondary transmissions were found to be caused by the 2019-nCoV"recurrent"group patients. Conclusions: Most of the 2019-nCoV patients had underlying diseases and active lesions were still found in CT images, so the possibility of virus replication may still exist. All"recurrent"patients had mild illness which may suggest that they were in recovery stage, and no evidence of transmission is found.

Abstract
Objective: To analyze the epidemic situation and influencing factors of plague in Dehong Dai and Jingpo Autonomous prefectures (Dehong) from 1950 to 2019, for the improvement of strategies on prevention and control of the disease. Methods: The epidemic situation and surveillance data of animal and human plague in Dehong prefecture from 1950 to 2019 were collected and analyzed by descriptive epidemiological methods. Multiple linear regression equations were established by SPSS 20.0 software to analyze the relationship between plague among animals and rat density and flea index, as well as the relationship between human plague and plague among animals. Results: In Dehong prefecture, plague experienced a phenomenon of epidemic-resting-epidemic-resting cycle, between 1950 and 2019. During this period, 614 epidemic spots were identified in 36 townships of five counties/cities,. Human plague had been prevalent for 15 years, with 1 153 human cases and 379 deaths involved. Between 1982 and 2019, 261 319 rodents were captured, of which Rattus flavipectus accounted for 70.95%(185 421/261 319). A total of 70 124 fleas were seized with 76.65%(53 752/70 124), xenopsylla cheopis as fleas. The index of fleas and free fleas were 0.57 and 0.22 respectively. A total of 1 577 strains of Yersinia pestis were isolated from 285 091 animal specimens and 418 strains of Yersinia pestis were isolated from 60 119 groups of fleas, with 255 F1 antibody positive samples were detected from 64 157 sera samples. Neither Yersinia pestis nor the outbreak of plague had been noticed since 2008. Correlations between both animal plagues and rat density, as well as human plague and animals plague were noticed from the regression analysis. Conclusions: The epidemics of plague were with long-term and stable nature, in Dehong prefecture. Affected by many factors, plague seemed in a resting period currently. However, we should be reminded that the fact that outbreak of plague may revive at some uncertaint point. Hence in order to prevent human plague, strategies as careful surveillance programs on animals, need to be strenthened.

Anticancer activity of sugiol against ovarian cancer cell line SKOV3 involves mitochondrial apoptosis, cell cycle arrest and blocking of the RAF/MEK/ERK signalling pathway. Arch Med Sci 2020; 16:428-435. [PMID: 32190154 PMCID: PMC7069438 DOI: 10.5114/aoms.2017.71420] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Accepted: 09/09/2017] [Indexed: 12/30/2022] Open
Abstract
INTRODUCTION Ovarian cancer is one of the leading causes of cancer-related deaths in women. Treatments for ovarian cancer include surgery followed by chemotherapy. However, the survival rate for ovarian cancer is still not satisfactory. Moreover, the current chemotherapy has numerous associated side effects. Therefore there is an urgent need to look for novel and more viable treatment options. Against this backdrop the present study was designed to evaluate the anticancer activity of sugiol against ovarian cancer cells. MATERIAL AND METHODS Cell viability was assessed by CCK8 assay, apoptosis by DAPI, AO/ER and annexin V/PI staining. Mitochondrial membrane potential and cell cycle analysis was performed by flow cytometry. Cell migration was investigated by wound healing assay. Protein expression was monitored by western blotting. RESULTS The results of the present study indicated that sugiol exerts significant (p < 0.0001) anticancer effects on SKOV3 cancer cells with an IC50 of 25 μM. However, sugiol exhibited less cytotoxicity against normal ovarian cells with an IC50 of 62.5 μM. The anticancer effects of sugiol were found to be due to G0/G1 cell cycle arrest and mitochondrial apoptosis. Sugiol also inhibited cell migration of SKOV3 cells dose dependently. Moreover, the results showed that sugiol could inhibit the RAF/MEK/ERK signalling pathway in a dose-dependent manner. CONCLUSIONS The results of the present study indicate that sugiol exerts potent anticancer effects on SKOV3 cells via induction of cell cycle arrest, mitochondrial apoptosis and inhibition of the RAF/MEK/ERK signalling pathway.

Abstract
A ferroelectric liquid crystal (FLC) cell with continuously alignment structure is realized by a polarization hologram method for fabricating a Pancharatnam-Berry (PB) lens, which is employed as a concave/convex lens. The PB phase can be maintained by the optical axis in-plane switching; meanwhile, its diffraction efficiency can be tuned in a certain range by electrically controlling azimuthal angle and optical biaxiality of the smectic helical structure realized by deformed helix ferroelectric liquid crystals. The measured diffraction efficiency of the fabricated device is up to 87% and the response time can be 300μs with a low electric voltage. The FLC PB lens can have potential applications in existing optical devices and the realization of FLC with continuous alignment structure can be further used for other LC-based optical devices.

Abstract
Objective: To understand the genotype of the Yersinia (Y.) pestis strains isolated from Heqing county, Yunnan province in 2017 and provide evidence for the prevention and control of plague in this area. Methods: Ten Y. pestis strains isolated from Heqing were typed by the detections of different region (DFR) and clustered regularly interspaced short palindromic repeats (CRISPRs) as well as multiple-locus variable-number tandem repeat analysis (MLVA). And the results were compared with those of the 93 Y. pestis strains from the adjacent plague foci of Heqing obtained from the established database for clustering analysis. Results: The results showed that Heqing strains had the same type of DFR (Genomovar 05) and CRISPRs (Cluster Ca7, Type 22) with isolates from the plague focus in Lijiang. Heqing strains and Lijiang strains were in the same cluster in MST and only VNTR loci N2117 and M23 of Heqing strains were different from that of Lijiang strains. Conclusion: The Y. pestis strains isolated from Heqing in 2017 were highly homogenous with the strains isolated from wild rodents in plague focus in Lijiang, and Heqing plague might be the result of further southward spread of Lijiang plague.

Abstract
Objective: To analysis the treatment effect of the ulnar osteotomy and ring-shaped ligament reconstruction for the treatment of old Monteggia fracture in children by using Meta analyze, and the difference of clinical curative effect was compared in order to provide the basis for the selection of clinical treatment options for old Monteggia fractures in children. Methods: We searched databases such as CNKI, Wanfang database, Medline, PubMed, Embase and Science through computer, at the same time, the references of relevant documents were retrieved manually, and the data processing was carried out by the RevMan5.3 statistical software provided by the Cochrane cooperation network by incorporating the exclusion criteria. The results were obtained and analyzed. Results: A total of 17 standard literature, 438 cases, 224 cases of ulnar osteotomy, 214 cases with ring ligament repair and reconstruction were obtained. The operation scheme, which was mainly based on the lengthening of ulna osteotomy, was superior to the reconstruction of ring ligament reconstruction. The complications and second operation rates of the former was less than that of the latter. Conclusion: The surgical methods for the reconstruction of the ulna osteotomy and the ring-shaped ligament have advantages and disadvantages. The choice of the operative plan for the old Monteggia fracture should be based on the following factors: the time of the old Monteggia fracture formation, the degree of the ulnar and radial deformity and the familiarity of the operative method.

Abstract
OBJECTIVE To investigate the effect and possible mechanisms of olmesartan medoxomil on atherosclerosis of apolipoprotein E knockout (ApoE(-/-)) mice. METHODS Sixteen 6-week-old male ApoE(-/-) mice were randomly divided into atherosclerosis model group fed with high fat diet, and olmesartan medoxomil intervention group fed with high fat diet and olmesartan medoxomil (10 mg·kg(-1)·day(-1,) per gavage). Eight C57BL/6 mice were fed with normal diet, and treated for 12 weeks.The blood pressure and the serum level of lipid were detected; the aorta were removed, oil red staining for plaque area, Hematoxylin and eosin (HE) staining for plaque morphology, Elastica van Gieson (EVG) staining for elastin, and picrosirius red (PSR) for collagen respectively; and the expression of cathepsin S (Cat S), smooth action protein (ASMA) and macrophage surface molecule-3 (Mac-3) were detected by immunohistochemisty analysis. RESULTS Serum cholesterol and low density lipoprotein levels were significantly higher in atherosclerosis model group than in control group[(15.08±1.64) vs (2.06±0.15) mmol/L, (15.60±1.05) vs (0.00±0.00) mmol/L] (all P<0.01), while triglyceride level was similar between the two group.In contrast to model group, the mice in intervention group showed no statistical difference in blood pressure and plasma lipid levels, while the plaque areas in the aorta were significantly decreased (P<0.05) as well as the expression of Cat S and Mac-3[(2.4±1.2) vs (8.8±3.2)%, (2.2±1.2) vs (7.2±2.8)%] (all P<0.01). In addition, the elastin levels, collagen contents, and the expression of ASMA remained significantly higher compared with model group (P<0.05). CONCLUSION Olmesartan medoxomil could slow down the atherosclerosis process, the possible mechanism was implicated with the suppression of Cat S and decreased inflammatory responses alongside the increased elastin and collagen contents.

Abstract
In this article, we disclose a fork grating (FG) based on the photo-aligned ferroelectric liquid crystal (FLC). The Digital Micro-mirror Device based system is used as a dynamic photomask to generated different holograms. Because of controlled anchoring energy, the photo alignment process offers optimal conditions for the multi-domain FLC alignment. Two different electro-optical modes namely DIFF/TRANS and DIFF/OFF switchable modes have been proposed where the diffraction can be switched either to no diffraction or to a completely black state, respectively. The FLC FG shows high diffraction efficiency and fast response time of 50µs that is relatively faster than existing technologies. Thus, the FLC FG may pave a good foundation toward optical vertices generation and manipulation that could find applications in a variety of devices.

Abstract
This study was designed to investigate the changes of high-mobility group box-1 (HMGB1) expression and its effects on regulating the angiogenesis of ovarian cancer. HMGB1 eukaryotic expression plasmid and artificially synthesized small interfering ribose nucleic acid (siRNA) were constructed to transfer SKOV3 cell, respectively. Western blot was adopted to investigate the changes of HMGB1, CXCL12 and vascular endothelial growth factor (VEGF) before and after the transfection and flow cytometry (FCM) was applied to detect SKOV3 apoptosis. Results revealed that the apoptosis rates of SKOV3 cell were 32.8±2.2%, 33.9±1.9% and 11.7±1%, respectively, in the control group, no-load group and transfection group after 2-d cisplatin treatment (10 μg/mL). The apoptosis rate in the transfection group was obviously lower than that in the control group and no-load group (p = 0.00) while no significant difference was found in the apoptosis rate in the other two groups (p = 0.75). Furthermore, the apoptosis rates of SKOV3 cell in the SKOV3 group, negative control group, SKOV3-ribose nucleic acid interfere (RNAi) group were 7.9±0.5%, 8.3±0.8% and 29.5±1.3% respectively. The apoptosis rate was notably higher in SKOV3-RNAi group than in the SKOV3 group and negative control group (p < 0.001) while no significant difference was found in the apoptosis rate in the other two groups (p = 0.89). Thus, it can be concluded that HMGB1 interference can reduce VEGF and CXCL12 expression in ovarian cancer cells, but increase the apoptosis of ovarian cancer cells. Moreover, HMGB1 is highly expressed in cytoplasm and karyon.

Abstract
Brain natriuretic peptide (BNP) is used as a marker of cardiac dysfunction to predict heart failure mortality. The significance of the prognostic ability of BNP for liver cirrhosis remains unknown, although the levels of BNP seen in cirrhosis are high. We aimed to determine whether the BNP level is related to the stage of cirrhosis and could serve as a prognostic marker of cirrhosis (predict the 1-year all-cause mortality). We recruited 92 patients at different stages of cirrhosis and 81 controls matched by age and gender for this study. At admission, cardiac physical examination and BNP measurements were performed. Upon discharge, the 89 patients were followed up for 12 months. The median BNP levels of patients with cirrhosis were 167.0 pg/mL, which were significantly higher than those of the control group (167.0 vs 34.8 pg/mL, P = 0.001). Serum BNP levels were positively correlated with the Child score, the grade of esophageal varices, a history of spontaneous bacterial peritonitis, and the presence of ascites and collateral circulation. BNP levels above the median were associated with an increased occurrence of death within 12 months of discharge (log rank P = 0.025), as determined by univariate and multivariate Cox regression analyses. Esophageal varices, large/medium volume ascites, and BNP levels were related to the clinical outcome (P = 0.034, 0.030, and 0.025, respectively). Together, these results suggested that serum BNP levels are significantly correlated with the stage of cirrhosis, suggesting that BNP levels might serve as a significant predictor for 1-year all-cause mortality.

Abstract
Brachymystax lenok is a cold freshwater fish accustomed to inhabit relatively high concentration of dissolved oxygen and clean upper streams. Here we present 13 polymorphic microsatellite primer pairs from rainbow trout to amplify in 32 B. lenok individuals from Ussuri River of China. The number of alleles ranged from two to seven with an average of 3.9 per locus. Observed heterozygosity ranged from 0.0625 to 0.9677. One locus showed significant deviation from Hardy-Weinberg equilibrium. These 13 loci will provide a good basis for investigation of B. lenok population structure and genetic diversity in different distribution region.

[PMID: 17306362 DOI: 10.1016/j.marenvres.2006.12.005] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2006] [Revised: 11/21/2006] [Accepted: 12/12/2006] [Indexed: 05/14/2023]
Abstract
We examined the variation in aboveground biomass accumulation and tissue concentrations of nitrogen (N), phosphorus (P), copper (Cu), zinc (Zn) and lead (Pb) in Phragmites australis (common reed), Spartina alterniflora (salt cordgrass), and Scirpus mariqueter throughout the growing season (April-October 2005), in order to determine the differences in net element accumulation and distribution between the three salt marsh macrophytes in the Yangtze River estuary, China. The aboveground biomass was significantly greater in the plots of S. alterniflora than in the plots of P. australis and S. mariqueter throughout the growing season (P<0.05). In August, the peak aboveground biomass was 1246+/-89 gDW/m(2), 2759+/-250 gDW/m(2) and 548+/-54 gDW/m(2) for P. australis, S. alterniflora and S. mariqueter, respectively. The concentrations of nutrients and heavy metals in plant tissues showed similar seasonal patterns. There was a steady decline in element concentrations of the aboveground tissues from April to October. Relative element concentrations in aboveground tissues were at a peak during the spring sampling intervals with minimum levels during the fall. But the concentrations of total nitrogen and total phosphorus in the belowground tissues were relatively constant throughout growing season. Generally, trace metal concentrations in the aboveground tissues of S. mariqueter was the highest throughout the growing season, and the metal concentrations of S. alterniflora tissues (aboveground and belowground) were greater than those of P. australis. Furthermore, the aboveground pools of nutrients and metals were consistently greater for S. alterniflora than for P. australis and S. mariqueter, which suggested that the rapid replacement of native P. australis and S. mariqueter with invasive S. alterniflora would significantly improve the magnitude of nutrient cycling and bioavailability of trace metals in the salt marsh and maybe transport more toxic metals into the water column and the detrital food web in the estuary.

Abstract
It was proposed by FDA that, the increase of survival rate and the improvement of quality of life must both be considered in cancer treatment. Based on the questionnaire designed by European Organization for Research and Treatment of Cancer (EORTC), the author studied the quality of life in 102 cases of prostate cancer and in 102 controls. With factor analysis method, a 30-item questionnaire was divided into six aspects to evaluate patients' quality of life: (1) activities of daily life; (2) family and social life; (3) physical symptoms of prostate cancer; (4) fatigue and malaise; (5) psychologic disturbance and distress and (6) sexual dysfunction. The results showed that there was statistical importance between each item when comparing case and control groups which proved the questionnaire an appropriate approach in assessing quality of life in patients with prostate cancer.

Abstract
In America and many European countries, prostate cancer is the most common cancer and the second leading cause of cancer death in men. Among 10-30% of all the men older than 50 years of age, a silent microscopic form of prostate cancer may be harbored. This high rate is similar throughout the world. However, few epidemiologic studies of prostate cancer have implicated its risk factors. A 1:1 matched case-control study looked into risk factors of prostate cancer. A total number of 102 cases of prostate cancer and 102 controls were surveyed. The results showed that high body mass index, history of urinary diseases, coitus frequency > 3 times per week, hormone drug use, and number of children > 3 are identified as risk factors of prostate cancer statistically, but physical labor, exercise, and age of first nocturnal emission > 18 are protective factors of prostate cancer.

Abstract
A 1:1 matched case-control study was conducted to investigate the etiological factors of childhood leukemia. It was found that there were five risk factors: (1) children living in the environmental pollution area, OR (95% CI) = 2.84 (1.14-7.10); (2) exposure to extreme low frequency electronmagnetic field (ELF), OR (95% CI) = 2.01 (1.18-3.42); (3) history of postnatal X-ray exposure, OR (95% CI) = 4.53 (1.68-12.21); (4) history of taking chloramphenicol, OR (95% CI) = 3.60 (1.62-8.01); (5) history of taking, antipyretic or analgesic drugs, OR (95% CI) = 1.93 (1.09-3.42). A protective factor was also discovered. Mothers often eating fish, pork and other meat foods, OR (95% CI) = 0.33 (0.18-0.59). The analysis of the population attributable risk showed that 91% of the childhood leukemia cases might attribute to these five risk factors. The interaction among these etiological factors was estimated. Results showed that there was a positive interaction between the X-ray exposure and chloramphenicol on additive model, the relative excess risk due to interaction (RERI) of childhood leukemia was 3.04.

Abstract
In order to study the risk factors associated with female breast cancer, two 1:2 matched case-control studies were conducted from 1986 to 1993 in five cities in Hubei province and from 1991 to 1994 in Pingdingshan coal mining districts in Henan province. The results of multivariate conditional logistic regression analysis showed that history of breast diseases, number of births, age of first birth were major risk factors for breast cancer in urban inhabitants. Their adjusted attributable risks (PARs) were 0.3917, 0.3564, 0.1414 respectively. The combined population attributable risks (PAR) for the three factors was 0.7419. History of breast disease, number of births, menstrual disorder, family history of breast cancer were major risk factors in the Mining districts. Their PARs were 0.1487, 0.4781, 0.1282, 0.0791 respectively. PAR for four factors was 0.6952.

Regulation of human chorionic gonadotropin secretion and messenger ribonucleic acid levels by follistatin in the NUCC-3 choriocarcinoma cell line. Endocrinology 1994; 134:2431-7.

Abstract
In this study, the NUCC-3 choriocarcinoma cell line was used as an in vitro placental cell model to investigate the effects of follistatin on basal and GnRH-stimulated hCG secretion and/or its subunit mRNA levels. Follistatin (1.5-100 ng/ml; 48 h) alone did not affect basal hCG secretion or its subunit mRNA levels. GnRH increased hCG secretion and hCG beta-subunit mRNA levels in a dose-dependent manner, with maximal effects (2.37- and 2.4-fold increases, respectively) at a dose of 10(-8) M after 24 h of culture (P < 0.001). The time-course study showed that the increase in hCG secretion induced by GnRH occurred between 6-48 h after treatment. Follistatin (6-100 ng/ml; 48 h) significantly suppressed GnRH-stimulated hCG secretion and hCG alpha- and beta-subunit mRNA levels, with maximal suppression of 73.1%, 106.9%, and 129.1%, respectively (P < 0.001). In addition, follistatin (25 ng/ml) inhibited hCG secretion in response to phorbol 12-myristate 13-acetate (100 nM) by 90.3%. However, follistatin had no effect on hCG secretion evoked by forskolin (10 microM), and no change in hCG secretion was observed after treatment with a calcium ionophore (A23187; 10 microM) alone or in combination with follistatin. Furthermore, there was no significant difference in the half-lives of hCG alpha and -beta mRNA induced by GnRH alone compared with those induced by GnRH plus follistatin (P > 0.1), indicating that follistatin did not affect the stability of hCG alpha and -beta mRNA. Our data suggest that follistatin inhibits GnRH-stimulated hCG secretion as well as hCG alpha- and beta-subunit mRNA levels in the NUCC-3 choriocarcinoma cell line by decreasing the rate of transcription through the second messenger transduction system-protein kinase-C, rather than by affecting the stability of mRNA. These findings indicate that follistatin may play an important role in the regulation of hCG production in the placenta during pregnancy.

Abstract
Between March and August 1986 in Huangshi City, serum samples were collected from 316 apparently healthy barbers as a study group, as well as from 361 healthy employees of department stores as a control group. They were tested for hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs) and antibody to hepatitis B core antigen (anti-HBc) by enzyme-linked immunoadsorbent assays. Barbers showed a prevalence higher than that in controls for HBsAg (16.8 vs. 9.2%, P less than 0.01), anti-HBs (67.1 vs. 45.9%, P less than 0.001), and anti-HBc (39.2 vs. 21.2%, P less than 0.001). The prevalence of at least one marker of hepatitis B virus (HBV) infection was significantly higher in barbers than in controls (86.1 vs. 61.7%, P less than 0.001). Although the socioeconomic status and education level did not correlate with the frequency of HBV markers, the prevalence of HBsAg increased in parallel with the duration of practice. Because of their high risk for HBV infection, barbers need to be screened for markers of HBV infection on a routine basis, and are prime candidates for immunoprophylaxis with hepatitis B vaccine.
