Rare Sagittal Compensatory Balance in Neuromuscular Scoliosis Complicated by Hydrocephalus: A Case Report.

Objective: This case report aims to present a rare case of thoracic lordosis and lumbar kyphosis and describe the posterior instrumented scoliosis correction performed. Case presentation: A 59-year-old female presented with low back pain. She had undergone ventriculoperitoneal shunt placement 8 years ago. I scored 76 on the Wechsler Adult Intelligence Scale. MRI of the lumbar spine showed spinal canal stenosis at L3/4, L4/5, and L5/S1. Full spine X-ray revealed thoracic lordosis and lumbar kyphoscoliosis， the coronal imbalance, and the sagittal compensatory balance. In order to avoid the risk of brain swelling and paraplegia, pedicle subtraction osteotomies (PSO) in the L2 and lumbar posterior instrumented scoliosis correction were performed under electroencephalogram and neuro electrophysiological monitoring. Shoulder imbalance was observed 1 year after surgery, but there was no loss of lumbar correction. Conclusion: In future cases of complex spinal deformity, it is important to observe whether there is cerebral ventricular dilatation on MRI before the operation. If severe thoracic lordosis is combined with lumbar scoliosis, over-correcting the lumbar scoliosis should be avoided to prevent shoulder imbalance.

Exogenous and Endophytic Fungal Communities of Dendrobium nobile Lindl. across Different Habitats and Their Enhancement of Host Plants' Dendrobine Content and Biomass Accumulation.

Both the biosynthesis and array of bioactive and medicinal compounds in plants can be influenced by interactions with endophytic and exogenous fungi. However, the composition of endophytic and exogenous fungal communities associated with many medicinal plants is unknown, and the mechanism by which these fungi stimulate the secondary metabolism of host plants is unclear. In this study, we conducted a correlative analysis between endophytic and exogenous fungi and dendrobine and biomass accumulation in Dendrobium nobile across five Chinese habitats: wild Danxia rock, greenhouse-associated large Danxia stone, broken Danxia stone, broken coarse sandstone, and wood spile. Across habitats, fungal communities exhibited significant differences. The abundances of Phyllosticta, Trichoderma, and Hydropus were higher in wild habitats than in greenhouse habitats. Wild habitats were host to a higher diversity and richness of exogenous fungi than were greenhouse habitats. However, there was no significant difference in endophytic fungal diversity between habitats. The differences between the fungal communities' effects on the dendrobine content and biomass of D. nobile were attributable to the composition of endophytic and exogenous fungi. Exogenous fungi had a greater impact than endophytic fungi on the accumulation of fresh weight (FW) and dendrobine in D. nobile. Furthermore, D. nobile samples with higher exogenous fungal richness and diversity exhibited higher dendrobine content and FW. Phyllosticta was the only genus to be significantly positively correlated with both FW and dendrobine content. A total of 86 strains of endophytic fungi were isolated from the roots, stems, and leaves of D. nobile, of which 8 strains were found to be symbiotic with D. nobile tissue-cultured seedlings. The strain DN14 (Phyllosticta fallopiae) was found to promote not only biomass accumulation (11.44%) but also dendrobine content (33.80%) in D. nobile tissue-cultured seedlings. The results of this study will aid in the development of strategies to increase the production of dendrobine in D. nobile. This work could also facilitate the screening of beneficial endophytic and exogenous fungal probiotics for use as biofertilizers in D. nobile.

A combination of electroacupuncture and auricular acupuncture for postoperative pain after abdominal surgery for gynaecological diseases: A randomized controlled trial.

BACKGROUND: Postoperative pain following laparotomy for gynaecological diseases is a common problem that requires effective management to ensure patient satisfaction and recovery. Despite the wide use of acupuncture for pain management, knowledge of its efficacy in managing postoperative pain is limited. Previous literature used either acupuncture or auricular acupuncture alone. However, the combined use of acupuncture and auricular acupuncture have not been studied yet. PURPOSE: This study examined the efficacy and feasibility of combined electroacupuncture and auricular acupuncture compared to a sham control in reducing pain during 5 days after a laparotomy for gynaecological diseases. This combined therapy was hypothesized to provide greater pain reduction than previous studies with less frequent treatment. STUDY DESIGN: Randomized sham-controlled, patient- and- assessor-blinded trial. METHODS: This trial recruited 72 patients scheduled for laparotomy in Hong Kong. Either acupuncture (n = 36) or non-invasive sham acupuncture (n = 36) was performed on the patients preoperatively (1 session) and postoperatively (once a day, up to 6 sessions). The primary outcome was pain at rest, measured using a numerical rating scale from postoperative days 0-5. Secondary outcomes such as analgesics consumption were also assessed. A data and safety monitoring board (DSMB) was established. RESULTS: All 72 randomized patients were included in the analysis. The acupuncture group had a smaller pain score at rest at 22 hrs (mean = 2.6) than the sham control group (mean = 4.0) (Post hoc intention to treat analysis, Linear regression, mean difference = -1.4, 95% confidence interval = [-0.2] -2.7, p = 0.029). No statistically significant between-group difference was found in other outcomes. No serious adverse event was observed. CONCLUSION: Perioperative acupuncture treatments are safe and feasible, but the efficacy of acupuncture is inconclusive.

Lactoferrin Is a Potential Activator of the Vitamin D Receptor in Its Regulation of Osteogenic Activities in C57BL/6J Mice and MC3T3-E1 Cells.

BACKGROUND: Lactoferrin (LF) has been shown to promote bone anabolism, and the vitamin D receptor (VDR) mediates the effects of vitamin D on bone. We hypothesized that LF improves bone health by increasing VDR expression. OBJECTIVES: We sought to determine the role of VDR activation in LF-induced osteogenic activity in vivo and in vitro and the underlying molecular mechanisms. METHODS: Sixty male C57BL/6J mice (aged 4 wk) were randomly assigned into 6 groups and fed vitamin D-deficient (VDD; 0 IU/kg) or vitamin D-normal diet (VDN; 1000 IU cholecalciferol/kg) and administered placebo or LF (100 or 1000 mg/kg body weight) by gavage for 24 wk. Trabecular bone structure was analyzed using micro-CT, and VDR expression was assessed by immunohistochemistry. In vitro, MC3T3-E1 cells were treated with 100 µg LF/mL to evaluate its effect on VDR expression. Finally, the direct recruitment of LF to the Vdr promoter was confirmed by chromatin immunoprecipitation assay. In addition, cells were transfected with pGL3-basic Vdr vector for monitoring Vdr promoter activation using luciferase assays. RESULTS: LF supplementation at 100 and 1000 mg/kg revealed an ∼6.5% (P < 0.05) increase in bone mineral density in mice on VDD diet and exhibited an enhanced expression of VDR in bone compared with control. This increased expression of VDR was also observed in the bone of mice on the VDN diet, but the effect was more pronounced in VDD diet. In vitro, compared with the control group, Vdr mRNA expression was 18 times greater (P < 0.05) and peaked at 2 h posttreatment of LF. By cotransfection of the pGL3-basic Vdr vector, LF induced luciferase activity by 30% (P < 0.05) in MC3T3-E1 cells. CONCLUSIONS: In vivo and in vitro, LF, a potential activator of VDR, promotes osteogenesis. This suggests that dairy products, which are rich in LF, may serve as a functional food to improve bone health.

Chemomodulatory effect of neferine on DMBA-induced squamous cell carcinogenesis: Biochemical and molecular approach.

BACKGROUND: Neferine (NEF) is nontoxic, bisbenzylisoquinoline alkaloid is derived from the seed embryo of lotus, a familiar medicinal plant. Although several mechanisms have been planned, an evident antitumor action pathway of NEF on the oral tumor is still not known. In the current study, we aimed at investigating the protecting effect of NEF against experimental oral carcinoma and clarify its possible mechanism through the induction of apoptosis, proliferation, and inflammatory signaling pathways. METHODS: The experimental hamsters were divided into four groups (I-IV) containing six hamsters each. The group I was control group, group II and III hamsters treated with 7,12-dimethylbenz(a)anthracene (DMBA) (0.5%) alone, thrice in a week for 10 weeks, and group III and IV hamsters received oral supplementation of NEF at a concentration of 15 mg/kg bw. All the hamsters were sacrificed after 16 weeks. RESULTS: Our results revealed that DMBA treated hamsters exhibited 100% oral tumor cell formation with high-tumor incidence (TI), tumor number (TN), tumor volume (TV), decreased levels of antioxidants, increased status of lipid peroxidation (LPO), and modulated the activities of liver marker agents as well as NF-kB, cell proliferation (PCNA), and p53 proteins. NEF supplementation in DMBA treated hamsters, resulted in delayed lesion synthesis, and brought back the levels of the biochemical parameters. In addition, immunostaining of NF-kB, PCNA, and p53 showed that they were inhibited by NEF. CONCLUSION: Thus, NEF might be considered a better chemopreventive drug in an experimental model of home-based primary care (HBPC). More research is necessary to study other pathways implicated in oral carcinomas and their modulation by NEF.

Favorable outcome of adjunctive traditional Chinese medicine therapy in liver cirrhosis: A large cohort study in Southwest China.

OBJECTIVE: To assess the effects of traditional Chinese medicine (TCM) on the survival of patients with liver cirrhosis (LC) in Southwest China. DESIGN: Single-center, ambispective cohort study conducted from 2012 to 2019. SETTING: Traditional Chinese Medicine Hospital of Dianjiang Chongqing, Southwest China. MAIN OUTCOME MEASURE: The primary outcome was the effect of TCM on the survival of patients with LC, as assessed with survival analysis and Cox regression model. RESULTS: Among the 691 patients with LC, 364 (52.68 %) received TCM treatment. The mean (standard deviation) follow-up period was 3.53 (1.62) years for non-TCM users and 4.17 (1.53) years for TCM users (P =  0.184). Multivariate analysis revealed that the use of TCM was associated with a significantly decreased risk of mortality (adjusted hazard ratio [HR] = 0.41, 95 % confidence interval [CI] = 0.30 - 0.54) compared with no TCM use. Similarly, the cumulative mortality rates were significantly lower among TCM users, across various subgroups of LC aetiologies. Among the commonly used TCM prescriptions, Xiao Chaihu Tang (XCHT, adjusted HR = 0.17, 95 % CI = 0.07 - 0.42), Yinchen Wuling San (adjusted HR = 0.31, 95 % CI = 0.14 - 0.66), Biejia Ruan Gan Jian (adjusted HR = 0.31, 95 % CI = 0.13 - 0.75), and Chaihu Shu Gan San (adjusted HR = 0.33, 95 % CI = 0.19 - 0.57) were the most effective in improving survival. CONCLUSIONS: Our results provide evidence for supporting that adjunctive TCM therapy may potentially improve the survival of patients with liver cirrhosis, and XCHT was the most effective TCM prescription in this study.

Changes in milk yield and composition of colostrum and regular milk from four buffalo breeds in China during lactation.

BACKGROUND: Chinese local buffalos are mainly used as draft animals because of their low productivity but their crossbreeding with Murrah and Nili-Ravi breeds can produce offspring with a greatly improved milk yield. However, no studies have reported the characteristics of milk produced during lactation by these crossbred buffalo. RESULTS: This study investigated changes in yield, and the physicochemical composition of milk of Murrah, Nili-Ravi, Murrah×local, Murrah×Nili-Ravi×local buffalos with milk yields of 1022.49 ± 90.26 kg, 1193.02 ± 97.65 kg, 805.46 ± 76.57 kg and 1499.35 ± 105.32 kg respectively over a 210-day period. The protein, fat, ash and total solids contents of milk from the hybrids decreased, but the yield of these nutritional components increased because of the greater improvement in milk yield. As lactation progressed, lactose content increased, but this change was not significant after the 15th day postpartum; the protein content decreased whereas fat content increased significantly during the first three days; ash content changed significantly during the first 24 h postpartum but further changes were not significant. Gel electrophoresis was used to identify the protein profile with no difference found between the four breeds. CONCLUSION: After crossbreeding, the milk production of triple-crossbred buffalo was higher than Murrah, Nili-Ravi and the local Chinese buffalo, making it a potential resource for the Chinese dairy market. The results of this experiment will provide basic data for making better use of buffalo milk, planning crossbreeding programs, and establishing standards for buffalo milk. © 2019 Society of Chemical Industry.

Alteration of the colostrum whey proteome in mothers with gestational hypothyroidism.

BACKGROUND: Gestational hypothyroidism (G-HypoT) is one of the most common thyroid diseases in pregnant women. Human milk, which closely links the mother with infant, is an important factor to the infant health. Here, we analyzed the colostrum whey proteome of women with or without G-HypoT. METHODS AND RESULTS: Using high-mass accuracy and high-resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS), 1055 proteins were identified. Tandem Mass Tags (TMT) analysis identified differentially expressed proteins between G-HypoT and non-G-HypoT mothers. Of 44 proteins identified, 15 proteins were significantly increased in G-HypoT colostrum whey, while 29 were significantly decreased. Analysis revealed that enzymes involved in carbohydrate metabolism, and that reflect the metabolic activities in breastfeeding women, including fructose-1, 6-bisphosphatase 1, phosphoglycerate mutase 1 were down-regulated. Cell structural proteins, biomarkers of mammary integrity development, including Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and actin were lower in G-HypoT colostrum whey. However, immune protein fragments like Ig gamma-3 chain C region increased in G-HypoT colostrum whey. CONCLUSION: These results implied that G-HypoT may changed human colostrum whey protein in composition level, decreasing levels of metabolic proteins and cell-structure proteins, while increasing levels of immune-related proteins, which may compromise or reflect mothers' and infants' health.

Yin Yang 1 plays an essential role in breast cancer and negatively regulates p27.

Yin Yang 1 (YY1) is highly expressed in various types of cancers and regulates tumorigenesis through multiple pathways. In the present study, we evaluated YY1 expression levels in breast cancer cell lines, a breast cancer TMA, and two gene arrays. We observed that, compared with normal samples, YY1 is generally overexpressed in breast cancer cells and tissues. In functional studies, depletion of YY1 inhibited the clonogenicity, migration, invasion, and tumor formation of breast cancer cells, but did not affect the clonogenicity of nontumorigenic cells. Conversely, ectopically expressed YY1 enhanced the migration and invasion of nontumorigenic MCF-10A breast cells. In both a monolayer culture condition and a three-dimensional Matrigel system, silenced YY1 expression changed the architecture of breast cancer MCF-7 cells to that resembling MCF-10A cells, whereas ectopically expressed YY1 in MCF-10A cells had the opposite effect. Furthermore, we detected an inverse correlation between YY1 and p27 expression in both breast cancer cells and xenograft tumors with manipulated YY1 expression. Counteracting the changes in p27 expression attenuated the effects of YY1 alterations on these cells. In addition, YY1 promoted p27 ubiquitination and physically interacted with p27. In conclusion, our data suggest that YY1 is an oncogene and identify p27 as a new target of YY1.

Immoderate inhibition of estrogen by anastrozole enhances the severity of experimental polyarthritis.

Aromatase inhibitors have become the standard of care for the adjuvant treatment of postmenopausal, hormone-sensitive breast cancer. Meanwhile, more and more breast cancer patients who are treated with aromatase inhibitors as adjuvant therapies often experience arthralgias and musculoskeletal aching, in some cases, have necessitated discontinuation of treatment. We therefore use a rat model of human RA to test the hypothesis that anastrozole, an aromatase inhibitor, could enhance arthritis. The parameters used for analyzing the disease severity included paw volume, radiology, histopathological examination, markers for cytokine profile, immunophenotypic assays, and immune response to type II collagen. Administration of anastrozole significantly increased the severity of arthritis. Anastrozole induced the increased levels of proinflammatory cytokines, IFN-gamma, IL-12, and the decreased levels of IL-4, IL-10 secretion. We further found that anastrozole suppressed the differentiation of naive T cells to Treg cells, and it blocked the balance of IgG2a/IgG1 in peripheral blood. Meanwhile, estradiol concentration was the lowest in the anastrozole group. In a well-established model of postmenopausal RA, anastrozole potently promote the progression of arthritis and the associated development of osteoporosis. This potential problem should alert the oncologists and other health professionals.
