Prediction of pre-eclampsia at St. Mary's hospital lacor, a low-resource setting in northern Uganda, a prospective cohort study. BMC Pregnancy Childbirth 2023; 23:101. [PMID: 36755228 PMCID: PMC9906950 DOI: 10.1186/s12884-023-05420-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Accepted: 02/01/2023] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND Pre-eclampsia is the second leading cause of maternal death in Uganda. However, mothers report to the hospitals late due to health care challenges. Therefore, we developed and validated the prediction models for prenatal screening for pre-eclampsia. METHODS This was a prospective cohort study at St. Mary's hospital lacor in Gulu city. We included 1,004 pregnant mothers screened at 16-24 weeks (using maternal history, physical examination, uterine artery Doppler indices, and blood tests), followed up, and delivered. We built models in RStudio. Because the incidence of pre-eclampsia was low (4.3%), we generated synthetic balanced data using the ROSE (Random Over and under Sampling Examples) package in RStudio by over-sampling pre-eclampsia and under-sampling non-preeclampsia. As a result, we got 383 (48.8%) and 399 (51.2%) for pre-eclampsia and non-preeclampsia, respectively. Finally, we evaluated the actual model performance against the ROSE-derived synthetic dataset using K-fold cross-validation in RStudio. RESULTS Maternal history of pre-eclampsia (adjusted odds ratio (aOR) = 32.75, 95% confidence intervals (CI) 6.59-182.05, p = 0.000), serum alkaline phosphatase(ALP) < 98 IU/L (aOR = 7.14, 95% CI 1.76-24.45, p = 0.003), diastolic hypertension ≥ 90 mmHg (aOR = 4.90, 95% CI 1.15-18.01, p = 0.022), bilateral end diastolic notch (aOR = 4.54, 95% CI 1.65-12.20, p = 0.003) and body mass index of ≥ 26.56 kg/m2 (aOR = 3.86, 95% CI 1.25-14.15, p = 0.027) were independent risk factors for pre-eclampsia. Maternal age ≥ 35 years (aOR = 3.88, 95% CI 0.94-15.44, p = 0.056), nulliparity (aOR = 4.25, 95% CI 1.08-20.18, p = 0.051) and white blood cell count ≥ 11,000 (aOR = 8.43, 95% CI 0.92-70.62, p = 0.050) may be risk factors for pre-eclampsia, and lymphocyte count of 800 - 4000 cells/microliter (aOR = 0.29, 95% CI 0.08-1.22, p = 0.074) may be protective against pre-eclampsia. A combination of all the above variables predicted pre-eclampsia with 77.0% accuracy, 80.4% sensitivity, 73.6% specificity, and 84.9% area under the curve (AUC). CONCLUSION The predictors of pre-eclampsia were maternal age ≥ 35 years, nulliparity, maternal history of pre-eclampsia, body mass index, diastolic pressure, white blood cell count, lymphocyte count, serum ALP and end-diastolic notch of the uterine arteries. This prediction model can predict pre-eclampsia in prenatal clinics with 77% accuracy.

Abstract
Background Preeclampsia has a deleterious effect on renal and liver function, which results in alterations of various biochemical tests. Therefore, the main aim of this study was to evaluate the role of some hepatic and renal biochemical tests in the diagnosis of preeclampsia. Methods A comparative cross-sectional study was carried out on a total of 126 pregnant women after 20th week of gestation who attended at the University of Gondar Comprehensive Specialized Hospital. The participants were divided into two groups as cases and controls. The case group consisted of 63 preeclamptic women, whereas the control group had 63 age and gestational week matched normotensive pregnant women. From each participant, three milliliters of blood was collected, the serum part was separated, and selected biochemical tests were measured using Humastar 800 chemistry analyzer. An independent t-test and receiver operating characteristics were done using SPSS 20 for comparison and diagnostic value determination of different biochemical tests between the study groups. Results The maternal serum aminotransferases, total bilirubin, Creatinine, and Urea levels were all significantly elevated in preeclamptic women compared to normotensive pregnant women. The receiver operating characteristics plots revealed that serum aspartate aminotransferase level had area under the curve of 0.89 (95% CI: 0.84–0.95) and can distinguish preeclampsia patients from normotensive pregnant women at cut-off value of ≥58.5 U/l with 74.6% sensitivity, 87.3% specificity, and 80.9% diagnostic accuracy. Serum Creatinine level had area under the curve of 0.91 (95% CI: 0.86–0.96), which enabled to indicate preeclampsia at a cut-off value ≥0.90 mg/dl with 77.8% sensitivity and 85.7% specificity. Conclusion An increased serum aminotransferases, total bilirubin, creatinine, and Urea levels in pregnant women could indicate the development of preeclampsia, and needs to be investigated. Among biochemical tests, serum Creatinine level was the best diagnostic marker of preeclampsia, followed by serum aspartate aminotransferase level.

Abstract
Preeclampsia is a multisystemic disorder which accounts for the high prevalence of maternal and perinatal morbidity and mortality, especially in middle and low-income countries. Currently, the primary intervention is the urgent delivery of the fetus, hence it would be advantageous to identify those who are likely to develop preeclampsia and the maternal and fetal outcomes. However, an array of risk factors makes these challenging. This review explores the potentials of liver biomarkers in predicting the occurrence and outcome of preeclampsia, which could be beneficial in reducing the burden of the disease. Liver dysfunction in preeclampsia results in a severe condition, hence liver function tests are specific predictors of outcome.

Abstract
OBJECTIVE To determine if second trimester mean platelet volume (MPV) and serum uric acid are reasonable predictors of preeclampsia (PE) or not, in patients at moderate and low risk. METHODS This prospective study was conducted on 9522 women at low or moderate risk for developing PE who underwent dual measurements of MPV and serum uric acid at late first trimester (10-12 weeks) and at second trimester (18-20 weeks) and subsequently divided into two groups; PE group (n = 286) who later developed PE and non-PE group (n = 9236). Test validity of MPV and serum uric acid was the primary outcome measure. Data were collected and analyzed. RESULTS Second trimester MPV is a good predictor for development of PE at a cutoff value of 9.55 fL with area under the curve (AUC) of 0.86, sensitivity of 95.2%, specificity of 66.7%, positive predictive value (PPV) of 87%, negative predictive value (NPV) of 85.7%, and accuracy of 86.7%. Second trimester serum uric acid is a good predictor for development of PE at a cutoff value of 7.35 mg/dL, with AUC of 0.85, sensitivity of 95.2%, specificity of 55.6%, PPV of 83.3%, NPV of 83.3%, and accuracy of 83.3%. Combination of both tests has a sensitivity of 100%, specificity of 22.2%, PPV of 75%, NPV of 100%, and accuracy of 76.7%. CONCLUSION Second trimester MPV and serum uric acid alone or in combination could be used as a useful biochemical markers for prediction of PE based on their validity, simplicity, and availability.

Abstract
Preeclampsia (PE) is a pregnancy complex disease, distinguished by high blood pressure and proteinuria, diagnosed after the 20th gestation week. Depending on the values of blood pressure, urine protein concentrations, symptomatology, and onset of disease there is a wide range of phenotypes, from mild forms developing predominantly at the end of pregnancy to severe forms developing in the early stage of pregnancy. In the worst cases severe forms of PE could lead to systemic endothelial dysfunction, eclampsia, and maternal and/or fetal death. Worldwide the fetal morbidity and mortality related to PE is calculated to be around 8% of the total pregnancies. PE still being an enigma regarding its etiology and pathophysiology, in general a deficient trophoblast invasion during placentation at first stage of pregnancy, in combination with maternal conditions are accepted as a cause of endothelial dysfunction, inflammatory alterations and appearance of symptoms. Depending on the PE multifactorial origin, several in vitro, in vivo, and in silico models have been used to evaluate the PE pathophysiology as well as to identify or test biomarkers predicting, diagnosing or prognosing the syndrome. This review focuses on the most common models used for the study of PE, including those related to placental development, abnormal trophoblast invasion, uteroplacental ischemia, angiogenesis, oxygen deregulation, and immune response to maternal-fetal interactions. The advances in mathematical and computational modeling of metabolic network behavior, gene prioritization, the protein-protein interaction network, the genetics of PE, and the PE prediction/classification are discussed. Finally, the potential of these models to enable understanding of PE pathogenesis and to evaluate new preventative and therapeutic approaches in the management of PE are also highlighted. Impact statement This review is important to the field of preeclampsia (PE), because it provides a description of the principal in vitro, in vivo, and in silico models developed for the study of its principal aspects, and to test emerging therapies or biomarkers predicting the syndrome before their evaluation in clinical trials. Despite the current advance, the field still lacking of new methods and original modeling approaches that leads to new knowledge about pathophysiology. The part of in silico models described in this review has not been considered in the previous reports.

Abstract
The occurrence of thrombocytopenia in 5% of pregnant women at delivery, described as gestational thrombocytopenia, is well documented. A commonly believed concept is that gestational thrombocytopenia is the result of gradually decreasing platelet counts in all women during pregnancy. The goal of our study was to evaluate the data supporting this concept. To learn what is known about platelet counts throughout normal pregnancies, we systematically reviewed all publications describing platelet counts during pregnancy. We identified 3,039 studies; 46 reporting ≥30 women with normal pregnancies were included in our analyses. The combined mean platelet counts from all studies supported the concept that platelet counts decrease during pregnancy and increase postpartum: first trimester, 251,000/µL (95% CI, 238,000-264,000/µL); second trimester, 238,000/µL (95% CI, 222,000-253,000/µL); third trimester, 224,000/µL (95% CI, 213,000-235,000/µL); delivery, 237,000/µL (95% CI, 209,000-264,000/µL); 4-8 weeks postpartum, 247,000/µL (95% CI, 207,000-287,000/µL). However, individual studies were inconsistent. Eleven longitudinal studies compared platelet counts on the same women at different times during gestation: seven reported a decrease; four reported no change. Ten cross-sectional studies compared platelet counts of different women at different times during gestation: five reported a decrease; five reported no change. Five studies compared platelet counts of pregnant to nonpregnant women: three reported that platelet counts were lower in pregnant women; one reported no difference; one reported that platelet counts were higher in pregnant women. These inconsistent data emphasize the need to accurately describe platelet counts throughout normal pregnancies. Accurate data are essential for evaluating the clinical importance of thrombocytopenia during pregnancy.

Abstract
The aim of the present study was to determine the preventive effects of the polysaccharide of Larimichthys crocea swim bladder (PLCSB) on CCl4-induced hepatic damage in ICR mice. The in vitro preventive effects of PLCSB on CCl4-induced liver cytotoxic effect were evaluated in BRL 3A rat liver cells using the MTT assay. The serum levels of AST, ALT, and LDH in mice were determined using commercially available kits. The levels of IL-6, IL-12, TNF-α, and IFN-γ were determined using ELISA kits. The pathological analysis of hepatic tissues was performed with H and E staining, and the gene and protein expressions were determined by RT-PCR and Western blotting, respectively. PLCSB (20 μg·mL(-1)) could increase the growth of BRL 3A rat liver cells treated with CCl4. The serum levels of AST, ALT, and LDH were significantly decreased when the mice were treated with two doses of PLCSB, compared with the control mice (P < 0.05). PLCSB-treated groups also showed reduced levels of the serum pro-inflammatory cytokines IL-6, IL-12, TNF-α, and IFN-γ. PLCSB could decrease the liver weight, compared to the CCl4-treated control mice. The histopathology sections of liver tissues in the 100 mg·kg(-1) PLCSB group indicated that the animals were recovered well from CCl4 damage, but the 50 mg·kg(-1) PLCSB group showed necrosis to a more serious extent. The 100 mg·kg(-1) PLCSB group showed significantly decreased mRNA and protein expression levels of NF-κB, iNOS, and COX-2, and increased expression of IκB-α compared with the CCl4-treated control group. In conclusion, PLCSB prevented from CCl4-induced hepatic damage in vivo.

Abstract
BACKGROUND/OBJECTIVES D. candidum is a traditional Chinese food or medicine widely used in Asia. There has been little research into the anticancer effects of D. candidum, particularly the effects in colon cancer cells. The aim of this study was to investigate the anticancer effects of D. candidum in vitro and in vivo. MATERIALS/METHODS The in vitro anti-cancer effects on HCT-116 colon cancer cells and in vivo anti-metastatic effects of DCME (Dendrobium canidum methanolic extract) were examined using the experimental methods of MTT assay, DAPI staining, flow cytometry analysis, RT-PCR, and Western blot analysis. RESULTS At a concentration of 1.0 mg/mL, DCME inhibited the growth of HCT-116 cells by 84%, which was higher than at concentrations of 0.5 and 0.25 mg/mL. Chromatin condensation and formation of apoptotic bodies were observed in cancer cells cultured with DCME as well. In addition, DCME induced significant apoptosis in cancer cells by upregulation of Bax, caspase 9, and caspase 3, and downregulation of Bcl-2. Expression of genes commonly associated with inflammation, NF-κB, iNOS, and COX-2, was significantly downregulated by DCME. DCME also exerted an anti-metastasis effect on cancer cells as demonstrated by decreased expression of MMP genes and increased expression of TIMPs, which was confirmed by the inhibition of induced tumor metastasis in colon 26-M3.1 cells in BALB/c mice. CONCLUSIONS Our results demonstrated that D. candidum had a potent in vitro anti-cancer effect, induced apoptosis, exhibited anti-inflammatory activities, and exerted in vivo anti-metastatic effects.

Abstract
The aim of the present study was to determine the preventive effect of the traditional Chinese medicine, Dendrobium candidum Wall ex Lindl. (D. candidum), on CCl4-induced hepatic damage in mice. The CCl4-induced hepatic damage mice were treated with D. candidum, and the serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), triglyceride (TG) and total cholesterol (TC) were determined. In addition, serum cytokine levels of interleukin (IL)-6, IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ were analyzed with kits, while liver tissues were analyzed using hematoxylin and eosin staining and reverse transcription polymerase chain reaction (RT-PCR). Furthermore, the contents of D. candidum were determined by nuclear magnetic resonance (NMR). D. candidum was demonstrated to successfully prevent hepatic damage in mice. The serum levels of AST, ALT and LDH were significantly decreased when the mice were treated with 200 and 400 mg/kg D. candidum, as compared with the control mice (P<0.05). The lowest enzymatic activities were exhibited in the 400 mg/kg D. candidum group, which produced similar results to the positive control drug, silymarin. In addition, in the 400 mg/kg D. candidum group, the highest levels of TG and TC were observed among the treated groups. D. candidum-treated groups also demonstrated reduced levels of the serum proinflammatory cytokines, IL-6, IL-12, TNF-α and IFN-γ. The sections of liver tissue examined during histopathology in the high concentration 400 mg/kg D. candidum group recovered well from CCl4 damage; however, the sections in the 200 mg/kg D. candidum group revealed necrosis to a more serious degree. RT-PCR analysis was conducted on inflammation-associated genes, including nuclear factor (NF)-κB, IκB-α, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2, in the livers of the mice. The 400 mg/kg D. candidum group demonstrated significantly decreased mRNA expression levels of NF-κB, iNOS and COX-2, but an increased expression level of IκB-α when compared with the CCl4-treated control group. Furthermore, using NMR, 11 compounds were identified in the D. candidum leaf, whose functional contents may aid the preventive effect observed in the current study. Therefore, D. candidum may potentially contribute to the prevention of CCl4-induced hepatic damage in vivo.

Abstract
The preventive effect of polysaccharide of Larimichthys crocea swimming bladder (PLCSB) and the increase of this effect by use of resistant starch (RS3) as the carrier for PLCSB on azoxymethane (AOM) and dextran sulfate sodium (DSS)-inducing colon carcinogenesis in C57BL/6 mice has been studied. RS3 microspheres carrying PLCSB (RS3 + PLCSB) were produced and evaluated as a potentially improved colon carcinogenesis therapy for this study. The body weight, colon length, and colon weight of mice were determined, and colonic tissues were histologically observed. The serum levels of proinflammatory cytokines and the inflammation and apoptosis-related genes in colonic tissue were also tested. The PLCSB or RS3 + PLCSB significantly suppressed AOM and DSS-induced body weight loss, colon length shortening and decreased the colon weight to length ratio. PLCSB or RS3 + PLCSB reduced the levels of the serum pro-inflammatory cytokines IL-6, IL-12, TNF-α, and IFN-γ to a greater extent compared with the control mice, and the levels of RS3 + PLCSB were more close to the normal mice than PLCSB treated mice. Histopathological examination of sections of colon tissues showed that the RS3 + PLCSB group recovered well from colon carcinogenesis; however, the tissue sections of the stachyose + starch could reduce the necrosis degree. PLCSB significantly induced apoptosis in tissues of mice (p < 0.05) by up-regulating Bax, caspase-3, and caspase-9, and down-regulating Bcl-2. The expression of genes associated with inflammation-related NF-κB, iNOS, and COX-2 genes, was significantly down-regulated, and IκB-α was up-regulated (p < 0.05). These results suggest that PLCSB is a potent preventive against in vivo colon carcinogenesis and that PLCSB with an RS3 carrier could increase the preventative effect in mice.

Abstract
Kuding tea (Ilex kudingcha C.J. Tseng) is drunk widely in China. The in vitro anticancer effects of Kuding tea were evaluated in TCA8113 human tongue carcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 200 μg/ml, Kuding tea exhibited an inhibitory effect of 75% in TCA8113 cells, which was higher than that observed at concentrations of 100 and 50 μg/ml (41 and 10% inhibition, respectively). Reverse transcription-polymerase chain reaction (RT-PCR) and western blot analyses of the apoptosis, inflammation and metastasis genes and proteins in Kuding tea-treated cancer cells were performed. Kuding tea significantly induced apoptosis in TCA8113 cancer cells (P<0.05) by upregulating Bax, caspase-3 and caspase-9 expression, and downregulating Bcl-2 expression. Expression of the NF-κB, iNOS and COX-2 genes that are associated with inflammation was significantly downregulated by Kuding tea, which demonstrated its anti-inflammatory properties. Kuding tea also exerted an anti-metastatic effect on cancer cells. This was demonstrated by the decreased expression of matrix metalloproteases (MMPs) and the increased expression of tissue inhibitors of metalloproteinases (TIMPs), and confirmed by the inhibition of the metastasis of U14 squamous cell carcinoma cells in imprinting control region (ICR) mice. The ICR mouse buccal mucosa cancer model was established by injecting the mice with U14 cells. Following injection, the wound at the injection site was topically treated with Kuding tea. It was observed that the tumor volumes for the group treated with Kuding tea were smaller than those from the control mice. Analysis of the sections of buccal mucosa cancer tissue demonstrated that the buccal mucosa cancer degrees of the Kuding tea-treated mice were weaker than that in the control mice. Similar results were observed in the lesion sections of the cervical lymph nodes. Based on these results, Kuding tea exhibited successful in vitro anticancer effects in TCA8113 cells and in vivo buccal mucosa cancer preventive activity.

Abstract
The antitumor activity of Juemingzi (Cassia tora L.) was investigated in mice that were fed various concentrations of the compound. Although mice fed a low concentration (50 mg/kg b.w.) of Juemingzi exhibited a high tumor weight, the higher feeding concentrations (100 and 200 mg/kg b.w.) were associated with lower weight tumors. The growth rate of mouse splenocytes that were treated with 200 mg/kg b.w. Juemingzi was determined using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide assay. This rate of proliferation was higher than that achieved with 100 and 50 mg/kg b.w. Juemingzi treatment by fetal bovine serum, lipopolysaccharide or concanavalin A. Compared with the lower concentrations of Juemingzi treatment, 200 mg/kg b.w. Juemingzi significantly (P<0.05) reduced aspartate aminotransferase, alanine transaminase and blood urea nitrogen levels. A high concentration of Juemingzi (200 mg/kg b.w.) significantly (P<0.05) increased the levels of tumor necrosis factor-α and interleukin-1β cytokines compared with those of the mice that were treated with 100 and 50 mg/kg b.w. Juemingzi.

Abstract
Bamboo salt, a Korean folk medicine, is prepared with solar salt (sea salt) and baked several times at high temperatures in a bamboo case. In this study, we compared the preventive effects of bamboo salt and purified and solar salts on hepatic damage induced by carbon tetrachloride in Sprague-Dawley rats. Compared with purified and solar salts, bamboo salts prevented hepatic damage in rats, as evidenced by significantly reduced serum levels of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase (P < 0.05). Bamboo salt (baked 9×) triggered the greatest reduction in these enzyme levels. In addition, it also reduced the levels of the proinflammatory cytokines interleukin (IL)-6, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α. Histopathological sections of liver tissue demonstrated the protective effect of bamboo salt, whereas sections from animals treated with the other salt groups showed a greater degree of necrosis. We also performed reverse transcription-polymerase chain reaction and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-α, and IL-1β in rat liver tissues. Bamboo salt induced a significant decrease (~80%) in mRNA and protein expression levels of COX-2, iNOS, TNF-α, and IL-1β, compared with the other salts. Thus, we found that baked bamboo salt preparations could prevent CCl4-induced hepatic damage in vivo.

Abstract
Ilex kudingcha C.J. Tseng (Kudingcha) is a traditional Chinese drink consumed in East Asia. The present study evaluated the in vitro anticancer effects of Kudingcha in MCF-7 human breast adenocarcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 200 μg/ml, Kudingcha inhibited the growth of the MCF-7 cells by 81%. This was a greater degree of inhibition than that observed at concentrations of 100 and 50 μg/ml (58 and 19%, respectively). To elucidate the inhibitory mechanisms underlying the anticancer effect of Kudingcha in cancer cells, the expression of genes associated with apoptosis and inflammation were measured using RT-PCR. Kudingcha significantly induced apoptosis, as determined by 4,6-diamidino-2-phenylindole (DAPI) staining, by upregulating Bax, caspase-3 and caspase-9, and downregulating Bcl-2. The expression of the NF-κB, iNOS and COX-2 genes associated with inflammation was significantly decreased (P<0.05) by Kudingcha, thus demonstrating its anti-inflammatory properties. Kudingcha has been reported to exhibit inhibitory effects of tumor metastasis induced in 26-M3.1 colon carcinoma cells in BALB/c mice. The results demonstrated that Kudingcha had potent in vitro anticancer effects; it induced apoptosis, had anti-inflammatory activities and exerted in vivo anti-metastatic effects. Additionally, the anticancer, anti-inflammatory and anti-metastatic effects of Kudingcha were stronger at high concentrations than at low concentrations.

Abstract
The buccal mucosa is the site with the highest risk of contracting a malignancy in habitual betel quid chewers who expose the buccal mucosa to high doses of carcinogens. Of all oral cancers, those of the buccal mucosa are associated with the poorest prognoses. Therefore, it would be helpful to have an animal model to evaluate new treatment modalities for buccal mucosa cancer. In the present study, we evaluated whether the imprinting control region (ICR) mouse animal model could be employed as a cancer model for buccal mucosa cancer. Sixty male ICR mice were randomly divided into two groups, a normal group (n=10) and a cancer-induced group (n=50). Each mouse in the cancer group was inoculated with 0.05 ml U14 cancer cell suspension (1×107/ml) on the buccal mucosa. Histological staining and gene expression assays revealed that neck lymph node metastasis animal models were established. After 20 days, the cheek tumor formation rate of the ICR mice reached 100%. Furthermore, the neck lymph node metastasis rate was 53%. We identified that U14 cells produce strong metastasis in ICR mice. Metastasis of the tumor to the lymph node began with carcinoma metastasis encroaching on the marginal sinus. Then it infiltrated to the cortex and medulla and the infiltration continued until the normal lymph node structure was completely damaged. This animal model may be employed in medical research on buccal mucosa cancer and cervical lymph node metastasis. In conclusion, our findings indicate that U14 cell-induced mouse buccal mucosa cancer may be a potential cancer model for human buccal mucosa squamous cell carcinoma.

Abstract
Cassia tora L. (Jue-ming-zi) is a traditional Chinese medicine widely used in East Asia. The in vitro anticancer effects of Jue-ming-zi were evaluated in TCA8113 human tongue carcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 1.0 mg/ml, Cassia tora L. inhibited the growth of TCA8113 cells by 72%; this inhibiton was greater than that by 0.5 and 0.25 mg/ml Cassia tora L. (43 and 16%, respectively). To elucidate the inhibitory mechanisms underlying the anticancer effect of Cassia tora L. in cancer cells, the expression of genes associated with apoptosis, inflammation and metastasis were measured using RT-PCR and western blot analysis. Cassia tora L. significantly induced apoptosis in cancer cells (P<0.05) by upregulating Bax, caspase-3 and caspase-9, and by downregulating Bcl-2. The expression of genes associated with inflammation, including NF-κB, iNOS and COX-2, was significantly downregulated (P<0.05) by Cassia tora L., demonstrating its anti-inflammatory properties. Cassia tora L. also exerted a significant anti-metastatic effect on cancer cells as demonstrated by decreased mRNA expression of matrix metalloprotease (MMP) genes and increased expression of tissue inhibitors of metalloproteinases (TIMPs), and as confirmed by the inhibition of induced tumor metastasis induced in 26-M3.1 colon cells in BALB/c mice. Our results demonstrated that Cassia tora L. exhibited the most potent in vitro anticancer effects, induced apoptosis, had anti-inflammatory activities and exerted in vivo anti-metastatic effects. Additionally, the anticancer, anti-inflammatory and anti-metastatic effects of the higher Cassia tora L. concentrations were stronger compared with those of the lower Cassia tora L. concentrations tested.

Abstract
Hawk tea (Litsea coreana Levl. var. lanuginose) is a traditional Chinese drink similar to green tea. In the present study, the preventive effects of Hawk tea on hepatic damage induced by carbon tetrachloride (CCl4) were studied in Sprague-Dawley rats. Silymarin was used as a positive control. Hawk tea was successfully shown to prevent hepatic damage in the rats. Serum levels of AST, ALT and LDH were significantly decreased when the rats were treated with varying concentrations of Hawk tea compared with silymarin (P<0.05). The lowest enzyme activities were exhibited in the 400 mg/kg Hawk tea group. This group showed reduced levels of the serum proinflammatory cytokines IL-6, IFN-γ and TNF-α. In particular, the IFN-γ level decreased markedly compared with the other concentration groups. The histopathology sections of liver tissue in the 400 mg/kg Hawk tea group recovered well from the CCl4 damage, but the sections of the other concentration groups showed necrosis to a more serious degree. Reverse transcription-polymerase chain reaction (RT-PCR) and western blot analyses of the inflammation-related genes iNOS, COX-2, TNF-α and IL-1β in the rat livers were tested. The 400 mg/kg Hawk tea group showed significantly decreased mRNA and protein expression levels of iNOS, COX-2, TNF-α and IL-1β compared with the control group. Accordingly, 400 mg/kg Hawk tea potentially contributes to the prevention of CCl4-induced hepatic damage in vivo. A 200 or 100 mg/kg dose of Hawk tea also demonstrated preventive effects against hepatic damage.

Abstract
OBJECTIVE To examine whether plasma levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) during the first 20 weeks of pregnancy can predict preeclampsia in the second half of pregnancy. METHODS The study population included 150,10 registered births. Receiver operating characteristic (ROC) curve analysis was used to describe the relationship between different values of AST and ALT during the first 20 weeks of pregnancy in the prediction of preeclampsia. RESULTS Using ROC curve analyses, elevated ALT levels were significantly associated with both mild preeclampsia (p < 0.001) and severe preeclampsia (p = 0.032). However, an ALT level of 50 IU/L had a sensitivity of only 3.3% (despite a specificity of 97%) in the prediction of severe preeclampsia. While no significant association was noted between AST levels and mild preeclampsia (p = 0.669), elevated levels of AST during this period were significantly associated with severe preeclampsia (p = 0.027). However, AST of 50I U/L had a sensitivity of only 2.0% (despite a specificity of 98%) in the prediction of severe preeclampsia. CONCLUSIONS Higher levels of the liver enzymes AST and ALT during the first 20 weeks of pregnancy are associated with higher risk for the development of severe preeclampsia in the second half of the pregnancy. Nevertheless, there is no clinical cutoff value that can be practically used for the prediction of preeclampsia.

Ever since it was first linked with the pathophysiology of pre-eclampsia, uric acid has been a routine test requested by many care-givers managing pregnant women with hypertensive disease of pregnancy for almost 100 years. Existing evidence however suggests that it has no definitive role in prediction, diagnosis or management of pre-eclampsia. We argue against routine uric acid testing in pregnancies complicated by hypertension not only because it has become a fruitless academic exercise but also because ceasing its routine use will ensure cost-savings for the health services.
