Dietary sodium butyrate positively modulated intestinal microbial community, but did not promote growth of largemouth bass (Micropterus salmoides).

This study investigated the effects of dietary sodium butyrate (NaB) on growth, serum biochemical indices, intestine histology, and gut microbiota of largemouth bass (Micropterus salmoides). A basal diet was formulated and used as the control diet (Con), and five additional diets were prepared by supplementing NaB (50%) in the basal diet at 2.0, 4.0, 8.0, 12.0, and 16.0 g/kg inclusion (NaB-2, NaB-4, NaB-8, NaB-12, and NaB-16 diets). Then, the six diets were fed to triplicate groups of largemouth bass juveniles (2.4 ± 0.1 g) for 8 weeks. NaB supplementation linearly and quadratically affected weight gain (WG) and feed intake (FI) (P < 0.05). The NaB-16 group displayed lower WG (- 6.8%) and FI than the Con group (P < 0.05), while no differences were found in WG and feed conversion ratio between the other NaB groups and Con group (P > 0.05). Serum alkaline phosphatase and lysozyme activities were higher in the NaB groups (P < 0.05), and D-lactate content was lower in the NaB-12 group (P < 0.05) than the control. Intestinal lipase activity in NaB-2, NaB-4 group, and villi width in NaB-8 group were also higher than those in the Con group (P < 0.05). Compared to the Con group, the intestinal abundances of Firmicutes and Mycoplasma were increased and the abundances of Proteobacteria, Achromobacter and Plesiomonas were decreased in NaB-4 and NaB-16 groups (P < 0.05). In conclusion, dietary NaB did not promote the growth of juvenile largemouth bass, but positively modulated the intestinal microbial community.

Efficacy of Getong Tongluo Capsule plus Clopidogrel hydrogen sulfate tablets Therapy Assisted by Home Rehabilitation Guidance in Convalescents from Cerebral Infarction.

Background: Cerebral infarction (CI) is one of the leading causes of death in middle-aged and elderly people, and there is a need to focus on overall rehabilitation during the recovery period of CI in the clinic, to provide a more reliable guarantee for the health of patients. Objective: To observe the therapeutic efficacy of Getong Tongluo Capsule (GTC) plus Clopidogrel hydrogen sulfate tablets (CHST) therapy assisted by home rehabilitation guidance in convalescents from CI, to provide clinical reference and evidence for future CI management. Methods: CI convalescents who visited the Fourth People's Hospital of Haikou City between 2016 and 2021 were selected as the research participants. Based on the assistance of home rehabilitation guidance, 44 patients receiving CHST treatment and 56 patients receiving GTC + CHST treatment were assigned to a control group (CG) and research group (RG), respectively. The blood viscosity of the two groups was compared before and after treatment. In addition, patients were assessed by the National Institutes of Health Stroke Scale (NIHSS), Mini-Mental State Examination (MMSE), Fugl-Meyer Assessment (FMA), Modified Barthel index (MBI), and Self-rating Anxiety/Depression Scale (SAS/SDS) scores. Finally, the adverse reaction rate was counted. Results: The post-treatment blood viscosity decreased in both cohorts and was lower in RG compared with CG (P < .001). Regarding various scale scores, NIHSS, SAS, and SDS were lower in RG than CG, while MMSE, FMA, and MBI were higher (P < .001). The adverse reaction rate was not significantly different between groups (P = .587). Conclusion: GTC + CHST therapy assisted by home rehabilitation guidance is effective in the treatment of CI patients in the convalescent stage and is worth recommending.

Clinical features of acute macular neuroretinopathy induced by Omicron / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the clinical features of acute macular neuroretinopathy(AMN)induced by Omicron.METHODS: A retrospective study. A total of 9 patients(18 eyes)diagnosed with AMN from December 2022 to January 2023 in the Hospital of Chengdu University of Traditional Chinese Medicine were included. Patients underwent spectral-domain optical coherence tomography(SD-OCT), fundus fluorescein angiography(FFA), fundus photography, autofluorescence(AF), infrared reflectance(IR), optical coherence tomography angiography(OCTA)and multicolor, etc. Furthermore, they were followed up for 1～3mo and observed the prognosis.RESULTS: The initial symptom of the Omicron-induced AMN was the sudden onset of central/paracentral scotoma in the eyes with or without impaired vision and metamorphopsia, and the scotoma could persist for at least 3mo. The image features of AMN are as follows. First, the SD-OCT examination showed the rupture of outer retinal layers, scattered hyperreflective lesions, and atrophy of outer retinal layers. In severe cases, hyperreflective lesions were seen in the inner nuclear layer(INL)or with microcystic cavities under the retinal pigment epithelium(RPE). Second, the OCTA examination demonstrated the decreased blood flow density of the deep capillary plexus(DCP)of the macula. Third, the IR examination showed the weak reflection of lesion areas. Fourth, the fundus photography demonstrated the localized brown wedge-shaped lesion.CONCLUSIONS: The Omicron-induced AMN is mostly found in young females, and the characteristic manifestation of fundus is damage to the outer retinal layers. The extent of fundus lesions is related to the systemic inflammatory response and ocular microcirculatory changes after infection. The multimodal fundus image examination and a history of Omicron infection are helpful to diagnose the Omicron-induced AMN.

Zingiber officinale: A Systematic Review of Botany, Phytochemistry and Pharmacology of Gut Microbiota-Related Gastrointestinal Benefits.

Ginger (Zingiber officinale Rosc.) is a traditional edible medicinal herb with a wide range of uses and long cultivation history. Fresh ginger (Zingiberis Recens Rhizoma; Sheng Jiang in Chinese, SJ) and dried ginger (Zingiberis Rhizoma; Gan Jiang in Chinese, GJ) are designated as two famous traditional Chinese herbal medicines, which are different in plant cultivation, appearances and functions, together with traditional applications. Previous researches mainly focused on the differences in chemical composition between them, but there was no systematical comparison on the similarity concerning research achievements of the two herbs. Meanwhile, ginger has traditionally been used for the treatment of gastrointestinal disorders, but so far, the possible interaction with human gut microbiota has hardly been considered. This review comprehensively presents similarities and differences between SJ and GJ retrospectively, particularly proposing them the significant differences in botany, phytochemistry and ethnopharmacology, which can be used as evidence for clinical application of SJ and GJ. Furthermore, the pharmacology of gut microbiota-related gastrointestinal benefits has also been discussed in order to explore better ways to prevent and treat gastrointestinal disorders, which can be used as a reference for further research.

Multidisciplinary treatment of pancreatic cancer: a case report.

Background: Carcinoma of the head of pancreas has a high malignant degree and the 5-year survival rate at 5%. For unresectable pancreatic cancer, the 5-year survival rate is even lower. The clinical diagnosis of pancreatic cancer is difficult, and surgical indications are difficult to grasp. Moreover, perioperative and postoperative management is complex, and patients with different conditions need more attention to implement a comprehensive diagnosis and treatment strategy. In the diagnosis and treatment of pancreatic cancer and even other cancers, multi-disciplinary diagnosis and treatment can provide reasonable, personalized and more effective plans for patients so that cancer patients can receive better treatment and improve their quality of life. The multi-disciplinary diagnosis and treatment model can respond to the complex needs to individual patients. Case Description: This model is designed according to each patient's comprehensive situation, including their clinical symptoms, biochemical indicators, body mass index, and psychological status, and the tumor position, pathological tissue typing, and invasion scope. Complications of tumors can be reduced if treatment is controlled and if radical treatments are used within a broader comprehensive care model, thereby improving the quality of life of patients to prolong their survival. In our case report, the overall survival is much longer than un-resectable pancreatic cancer (median overall survival 6-9 months. The female patient was 53 years old. Her chief complaints were yellow skin, yellow urine, and absorption emaciation for 1 month. The preliminary diagnosis was postoperative pancreatic cancer. CT reexamination suggested portal vein liver metastasis. Repeated gastrointestinal bleeding occurs over the course of the disease. Postoperative review suggested recurrence, and she was admitted to First Affiliated Hospital, Army Medical University. During the treatment, the disease progressed to gastrointestinal bleeding, ascites, and jaundice. Conclusions: After multidisciplinary treatment (MDT) discussion, targeted treatment strategies were developed to improve the symptoms and improve the quality of life of the patients.

Schisandrin B promotes TH1 cell differentiation by targeting STAT1.

Schisandrin B (Sch B) is the major active ingredient of the traditional Chinese medicine Schisandra chinensis and has antitumor activity, anti-inflammatory activity. CD4+ Th subsets orchestrate immune responses to plenty of pathogen infections and participate in the pathogenesis of many immune-related diseases. However, little is known about the relationship between Sch B and T cell differentiation. Here, we showed that Sch B might participate in T cell receptor signaling pathway by using the TCMIO database. Importantly, Sch B promoted TH1 cell differentiation. Furthermore, Sch B did not affect TH2 cell and Treg differentiation. Mechanismly, Sch B increased the level of IFN-γ of CD4+ T cells by upregulating the phosphorylation of STAT1 protein. Then, STAT1 promoted T-bet expression in CD4+ T cells. In conclusion, Sch B modulates the differentiation of naïve CD4+ T cells into TH1 subset by STAT1/T-bet signaling, which may have the potential for the treatment of T cell-mediated-immune diseases.

Neobavaisoflavone-mediated TH9 cell differentiation ameliorates bowel inflammation.

Neobavaisoflavone (Neo), is the active constituent of the herb Psoralea corylifolial, used in the traditional Chinese medicine, and has anti-inflammatory activity, but whether Neo could regulate colitis remains unclear. T helper 9 (TH9) cells, a subset of CD4+ T helper cells characterized by secretion of IL-9, have been reported to be involved in the pathogenesis of many autoimmune and inflammatory diseases, but whether Neo could control TH9 cell differentiation also remains unclear. Here, we found that Neo could decrease IL-9 production of CD4+ T cells by targeting PU.1 in vitro. Importantly, Neo had therapeutic effects on DSS-induced colitis. Furthermore, we identified TH9 cells as the direct target of Neo for attenuating bowel inflammation. Therefore, Neo could serve as a lead for developing new therapeutics against inflammatory bowel disease.

Metabolomics of Spleen-Yang deficiency syndrome and the therapeutic effect of Fuzi Lizhong pill on regulating endogenous metabolism.

ETHNOPHARMACOLOGICAL RELEVANCE: Spleen-Yang deficiency (SYD) is one of the primary causes of many digestive diseases, such as ulcerative colitis (UC), and irritable bowel syndrome (IBS), but its endogenous metabolic characteristics are still unclear. Fuzi Lizhong pill (FLZP) is well-known for its powerful capacity for treating SYD; however, its mechanisms require further study. AIM OF THE STUDY: Herein, our present study aimed to investigate the essence of SYD from the perspective of metabolomics, and tried to reveal the anti-SYD action mechanisms of FLZP. MATERIALS AND METHODS: Firstly, the compound factor modeling method with the principle of "indiscipline in diet + excessive fatigue + intragastric administration of Senna water extracts" was used to establish Sprague Dawley (SD) rats as SYD model. Then, the visceral index, motilin (MTL), malonaldehyde (MDA), Interleukin 1 alpha (IL-1α), and Interleukin 6 (IL-6) levels were used to verify the anti-SYD effect of FLZP. In addition, serum samples were analyzed by UPLC-QE/MS metabolomics technique. Finally, the metabolic pathways associated with specific biomarkers were analyzed to research the possible mechanism underlying the action of FLZP. RESULTS: The expression of MTL, MDA, IL-1α, and IL-6 were regulated by FLZP, which suggested that it has relieved diarrhea and gastrointestinal motility disorder caused by SYD and had an anti-peroxidation, anti-inflammatory, and immune regulation effect. A total of 75 metabolites were found to be the potential biomarkers of SYD. Moreover, FLZP regulates 21 metabolites and 10 vital pathways including the tricarboxylic acid (TCA) cycle, sphingolipid metabolism, and histidine metabolism. CONCLUSION: SYD primarily causes disorders of amino acid metabolism, lipid metabolism, carbohydrate metabolism, metabolism of cofactors and vitamins, nucleotide metabolism, and translation. In addition, FLZP regulated carbohydrate, lipid, and amino acid metabolisms, gastrointestinal motility, digestive juice secretion, immune regulation, as well as antioxidant effects. Hence, FLZP had a good therapeutic effect on treatment of SYD. It might be a promising therapeutic agent for the treatment of SYD-related diseases.

Schisandrin B-mediated TH17 cell differentiation attenuates bowel inflammation.

Schisandrin B (Sch B) is the major active constituent of the traditional Chinese medicine Schisandra chinensis and has anti-inflammatory activity, but the target of Sch B remains unclear. T helper 17 (TH17) cells have been involved in the pathogenesis of many autoimmune and inflammatory diseases. Here, we showed that Sch B could decrease IL-17A production of CD4+ T cells by targeting STAT3 in vitro. Importantly, Sch B has therapeutic effects on DSS-induced acute and chronic colitis, CD4+CD45RBhigh T cell-induced colitis. Furthermore, we identified TH17 cells as the direct target of Sch B for mediating its anti-inflammatory activity. Sch B could serve as a lead for developing new therapeutics against TH17 cells or IL-17A cytokine-driven diseases.

Feasibility Analysis of Wumeiwan in Treatment of Advanced Biliary Tract Cancers / 中国实验方剂学杂志

Biliary tract cancers are group of highly heterogeneous malignant tumors derived from gallbladder and bile duct epithelium， including gallbladder cancer and cholangiocarcinoma， with a high degree of malignancy. When diagnosed， the course of disease often develops to the middle and late stage， with a poor prognosis. It is difficult to treat the advanced biliary tract cancers， with a lack of unified chemotherapy standard and targeted drugs. Traditional Chinese medicine（TCM） compound has multi-target， multi-link and multi-path characteristics， with effects in stabilizing tumor， alleviating clinical symptoms， alleviating side effect of radiotherapy and chemotherapy， and improving the quality of life. Especially in the treatment of advanced cancer patients， it plays an irreplaceable role. Therefore， it is concerned by many researchers. According to TCM， the pathogenesis of patients with advanced biliary tract cancers are mainly due to asthenia of healthy Qi and sthenia of pathogenic factors， Yin-Yang disharmony， and simultaneous occurrence of cold and heat. The location of the disease is related to liver， gallbladder， spleen， stomach and kidney. Because the advanced biliary tract cancers are similar to Jueyin syndrome in disease location， course and disease， Wumeiwan is often used in clinical treatment. Based on "theory， method， prescription and medicine" of TCM， Wumeiwan has the effect in regulating cold and heat， clearing the upper and lower temperature， warming the liver and supporting Yang， attacking and supplementing simultaneously， balancing the liver， spleen and kidney， which conforms to the TCM syndrome characteristics of advanced biliary tract cancers， according to modern Chinese medicine pharmacology， many effective ingredients in Wumeiwan have the effects in inducing tumor cell apoptosis， inhibiting tumor cell proliferation and reducing tumor cell proliferation， reducing inflammatory response in the body， inhibiting angiogenesis， reversing multidrug resistance of tumor cells and regulating immunity. This paper analyzes the feasibility of treatment of advanced biliary tract cancers with Wumeiwan from the perspective of traditional Chinese and Western medicine， so as to provide reference for clinical comprehensive treatment of advanced biliary tract cancers and the experimental study of TCM.

Effectiveness and Safety of Moxibustion Robots on Primary Dysmenorrhea: A Randomized Controlled Pilot Trial / 中国结合医学杂志

OBJECTIVE@#To conduct a pilot trial to explore the effectiveness and safety of moxibustion robots in treating primary dysmenorrhea (PD) and evaluate its feasibility in clinic.@*METHODS@#A total of 70 participants with PD were allocated to either moxibustion robot (MR) group (35 cases) or manual moxibustion (MM) group (35 cases) using computer-generated randomization. One acupoint Guanyuan (CV 4) was selected to receive moxa heat stimulation. Two groups of participants were given 3 menstrual cycles of MM and MR treatment respectively (once a day, 5 days a session) and received another 3 menstrual cycles follow-up. The degree of pain was evaluated by short-form McGill pain questionnaire (SF-MPQ) and the symptoms of dysmenorrhea were evaluated by Cox Menstrual Symptom Scale (CMSS). The safety was measured by the occurrence rate of adverse events (AEs), including burns (blisters, red and swollen), itching, bowel changes, menstrual cycle disorder, menorrhagia and fatigue, etc. RESULTS: A total of 62 patients completed the trial, 32 in MR group and 30 in MM group. Compared with baseline, scores of SF-MPQ and CMSS significantly decreased in both groups (P0.05). The total occurrence rate of AEs in MR group was 2.1%, which was significantly lower than MM group (7.2%, P<0.05).@*CONCLUSIONS@#MR has the same effect as MM at SF-MPQ and CMSS in patients with PD. However, MR is safer than MM (Trial registration No. ChiCTR1800018236).

Development and application of a moxibustion instrument with multi-jointed manipulator / 中国针灸

In view of the limitations of the existing moxibustion instruments, i.e. possible accidental injury when using moxibustion instruments, the negative effects of products from moxibustion instruments on treatment efficacy and health of medical staff and patients, a moxibustion instrument with multi-jointed manipulator is designed. This moxibustion instrument could accurately control the temperature, maintain a safe moxibustion distance, automatically process the burning ashes of moxa and selectively handle moxa smoke. The experimental results shows that this instrument could maintain the constant temperature of target acupoint, reduce the risk of empyrosis, and reasonably deal with the products of moxibustion. The purification rate of moxa smoke is 44.9%, which not only ensures the therapeutic effect of moxa smoke, but also reduces the negative effects of high-concentration moxa smoke on the health of medical staff and patients.

Effects of different doses of metformin on bone mineral density and bone metabolism in elderly male patients with type 2 diabetes mellitus.

BACKGROUND: Diabetes is a chronic disease, which may cause various complications. Patients with diabetes are at high risk of bone and joint disorders, such as osteoporosis and bone fractures. In addition, it became widely accepted that diabetes has an important impact on bone metabolism. Metformin is a commonly used and effective first-line treatment for type 2 diabetes. Some glucose-lowering agents have been found to have an effect on bone metabolism. The present study explored if different doses of metformin have an effect on bone mineral density (BMD) and bone metabolism in type 2 diabetes. AIM: To investigate the effects of different doses of metformin on BMD and bone metabolism in elderly male patients with type 2 diabetes mellitus. METHODS: A total of 120 elderly male outpatients with type 2 diabetes mellitus who were admitted to our hospital were included in the study from July 2018 to June 2019. They were randomly assigned to an experimental group and a control group with 60 patients in each group. Patients in the experimental group were given high dose metformin four times a day 0.5 g each time for 12 wk. Patients in the control group were given low dose metformin orally twice a day 0.5 g each time for 12 wk. The changes in bone mineral density and bone metabolism before and after treatment and the efficacy rate of the treatment were compared between the two groups. RESULTS: There was no significant difference in the efficacy rate between the two groups (P > 0.05). Before the treatment, there was no significant difference in BMD and bone metabolism between the two groups (P > 0.05). However, after the treatment, BMD and bone metabolism were improved in the two groups. Moreover, BMD and 25-hydroxyvitamin D were significantly higher in the experimental group than in the control group, and N-terminal/midregion and ß-isomerized C-terminal telopeptides were significantly lower in the experimental group than in the control group (all P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P > 0.05). CONCLUSION: Both high and low dose metformin can effectively control the blood glucose levels in elderly male patients with type 2 diabetes mellitus. However, the benefits of high dose metformin in improving BMD and bone metabolism level was more obvious in patients with type 2 diabetes mellitus.

[Preparation and in vitro quality evaluation of curcumin supersaturated self-nanoemulsion].

In order to improve the supersaturation and maintenance time of drug dispersion in curcumin self-nanoemulsion(CUR-SNEDDS), precipitation inhibitors(PPIs) were introduced to prepare curcumin supersaturated self-emulsion(CUR-SSNEDDS). The composition of CUR-SNEDDS prescriptions was selected through the solubility test, the compatibility of oil phase and surfactant, the investigation of the emulsifying ability of the surfactant and the drawing of the pseudo-ternary phase diagram. Analytic hierarchy process was used in combination with central composite design-response surface method to optimize the prescription. The type and dosage of precipitation inhibitors(PPIs) were selected to maintain the supersaturated concentration and duration of CUR in artificial gastrointestinal fluids. At the same time, polarizing microscope was used to evaluate the crystallization inhibition effect and the quality and in vitro release behavior of CUR-SSNEDDS. The prepared CUR-SSNEDDS prescription was capryol 90-kolliphor RH40-transcutol HP-Soluplus(7.93∶66.71∶25.36∶5), with the drug loading of(65.12±1.25) mg·g~(-1). CUR-SSNEDDS was transparent yellow, and the nanoemulsion droplets were spherical with uniform distribution. The emulsification time was(21.02±0.13) s, the average particle size was(57.03±0.35) nm, the polydispersity index(PDI) was(0.23 ± 0.01), and the Zeta potential was(-18.10±1.30) mV. CUR-SSNEDDS significantly inhibited the generation and growth of crystals after in vitro dilution. The supersaturation could be maintained above 10 within 2 h, and the dissolution rate and degree of CUR in artificial gastrointestinal fluid were significantly increased. Soluplus could effectively maintain the supersaturated state of CUR and enhance CUR dissolution in vitro.

RESULTS: In this study, the interaction of chemical compounds between licorice and toxic herbal medicine, pharmacological effect of licorice, and the effect of licorice on pharmacokinetics of toxic compounds are considered as the main mechanisms underlying the effects of licorice in combination preparations. Besides, ethnobotany, ethnopharmacological uses and chemical constituents have been summarized. CONCLUSION: This work comprehensively reviews the state on ethnobotany, ethnopharmacological uses, phytochemicals, combined applications, quality control and toxicology of licorice. It will provide systematic insights into this ancient drug for further development and clinical use.

Laparascopic Ladd's procedure as treatment alternative, when parenteral or prolonged hospital nutrition is not an option for superior mesenteric artery syndrome.

OBJECTIVES: Superior mesenteric artery syndrome (SMAS) is an uncommon cause of duodenal obstruction in pediatric patients. It is extremely rare in young infants. The classic treatment for SMAS has been an open or laparoscopic duodenojejunostomy when conservative medical therapy failed to resolve the obstruction. We herein reported 3 cases of SMAS in infants treated by laparoscopic Ladd's procedure. The advantages and feasibility of laparoscopic Ladd's procedure applied for SMAS in infants were discussed. METHODS: Three cases of infants with SMAS subjected to laparoscopic Ladd's procedure in our hospital were collected from January 2014 to December 2015. The patients' age, operative time, postoperative hospital observation, resumption of full diet, and postoperative complications were analyzed. RESULTS: The median age at operation was 8 months (range, 6-9 months). The mean body weight was 7.9 kg (range, 6.5-8.8 kg). The mean operative time was 66.7 min (range, 65-75 min). The mean postoperative hospital stay was 4.3 days (range, 4-5 days) and the follow-up was 20.7 months (range, 12-34 months) without any specific postoperative complications. CONCLUSION: Based on our reports, laparoscopic Ladd's procedure is a reliable and practicable minimally invasive surgery for in infants with SMAS.

Effect of Active Components of Traditional Chinese Medicine in Resisting Gallbladder Carcinoma / 中国实验方剂学杂志

Allbladder cancer is highly malignant and has few effective therapeutic drugs. Traditional Chinese medicine (TCM) has attracted the attention from researchers because of its multi-target, multi-link, multi-channel and less toxic side effect. In recent years, the basic studies of gallbladder cancer have made certain achievements in active components of TCM. Relevant experimental studies have extended to the lever of cells, molecules and genes. The main mechanism of experimental research include inhibiting tumor cell proliferation, inducing tumor cell apoptosis, inhibiting cell metastasis, inhibiting cell migration, influencing signal transduction pathway, enhancing sensitivity of chemotherapeutic drugs, and inhibiting tumor angiogenesis. The existing experimental studies have showed that active components of TCM have certain curative effect on gallbladder cancer, but with many problems. For example, although the extract of active components of TCM shows an anti-tumor activity, the specific composition and chemical molecular structure are still unclear. Most studies focus on the level of in vitro cell experiments, but only a few in vivo experimental studies have been carried out in animals. Therefore, more in-depth studies need to be carried out in the future. Currently, most of the mechanisms of anti-gallbladder cancer of active components of TCM are classical signaling pathways. The next step is to find new signaling pathways and new targets. In addition, under the guidance of TCM theory, the future studies of TCM compound can bring advantages of TCM against tumor into full play. The experimental study on the mechanism of action of active components of TCM in the treatment of gallbladder cancer is summarized as follows, which is helpful for researchers to understand the current experimental studies on active components of TCM in gallbladder cancer, in order to conduct more in-depth studies. Basic experimental studies on gallbladder cancer can provide theoretical basis for clinical treatment.

Vitamin D status and determinants among children aged 6 to 23 months in 4 poverty-stricken ethnic minority areas of Yunnan Province / 中华疾病控制杂志

Objective To investigate the vitamin D (VD) level and determinants among young children aged 6 to 23 months in 4 poverty-stricken ethnic minority areas of Yunnan Province. Methods Multistage stratified cluster sampling method was used. 1 255 young children aged 6-23 months from 3 to 4 towns of Jianchuan County, Yiliang County, Mojiang County and Lushui County. Questionnaires on caregivers, physical and serum 25(OH)D measure were achieved. VD level and influencing factors were described and analyzed. Results Overall VD level was 20.6(16.3,25.4) ng/ml. The proportion of VD deficiency, VD insufficiency and VD sufficiency were 7.1%, 39.2% and 53.7% respectively. The risk of VD insufficiency elevated with children’age increasing or no VD supplement (P<0.05). Hani minority can decrease the risk of VD deficiency and insufficiency (all P<0.05). Thus, the risk of VD deficiency and insufficiency in children of female, Lisu or Bai minority, or in children who had no nutritional package supplement would increase (all P<0.05). Conclusions The VD level of children aged 6-23 months in poverty-stricken ethnic minority areas of Yunnan Province was low. VD insufficiency was dominating. The intervention of VD deficiency and insufficiency may focus on the children of female, Lisu minority, Bai minority or older than 18 months. This study highlight that enhancing caregivers’ knowledge of VD nutrition, adding VD and nutritional package supplement actively are beneficial to improve VD nutrition of young children in minority poverty areas of Yunnan.

Periostin involved in the activated hepatic stellate cells-induced progression of residual hepatocellular carcinoma after sublethal heat treatment: its role and potential for therapeutic inhibition.

BACKGROUND: Incomplete thermal ablation may induce invasiveness of hepatocellular carcinoma (HCC). Here, we investigated whether activated hepatic stellate cells (HSCs) would accelerate the progression of residual HCC after sublethal heat treatment, and thus sought to identify the potential targets. METHODS: Hepatocellular carcinoma cells were exposed to sublethal heat treatment and then cultured with the conditioned medium from activated HSCs (HSC-CM). The cell proliferation, migration, invasion and parameters of epithelial-mesenchymal transition (EMT) were analyzed. In vivo tumor progression of heat-treated residual HCC cells inoculated with activated HSCs was studied in nude mice. RESULTS: HSC-CM significantly enhanced the proliferation, motility, invasion, prominent EMT activation and decreased apoptosis of heat-exposed residual HCC cells. These increased malignant phenotypes were markedly attenuated by neutralizing periostin (POSTN) in HSC-CM. Furthermore, exogenous POSTN administration exerted the similar effects of HSC-CM on heat-treated residual HCC cells. POSTN induced the prominent activation of p52Shc and ERK1/2 via integrin ß1 in heat-exposed residual HCC cells. Vitamin D analog calcipotriol blocked POSTN secretion from activated HSCs. Calcipotriol plus cisplatin significantly suppressed the activated HSCs-enhanced tumor progression of heat-treated residual HCC cells via the inhibited POSTN expression and the increased apoptosis. CONCLUSIONS: Activated HSCs promote the tumor progression of heat-treated residual HCC through the release of POSTN, which could be inhibited by calcipotriol. Calcipotriol plus cisplatin could be used to thwart the accelerated progression of residual HCC after suboptimal heat treatment.
