OBJECTIVE: To observe the effects of Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture therapy on the expression of hypoxia-inducible factor 1α (HIF-1α) and Nod-like receptor protein 3 (NLRP3) in cerebral ischemia-reperfusion rats, and to explore the mechanism of acupuncture against cerebral ischemia-reperfusion injury. METHODS: Seventy-two male SD rats were randomly divided into a sham-operation group, a model group, an acupuncture group and a non-point acupuncture group, with 18 rats in each one. Using modified Longa thread embolization method, the rat model of acute focal cerebral ischemia was prepared; and after 2 h ischemia, the reperfusion was performed to prepared the model of cerebral ischemia-reperfusion. Immediately after reperfusion, Xingnao Kaiqiao acupuncture method was applied to bilateral "Neiguan" (PC 6) and "Shuigou" (GV 26) in the acupuncture group, while in the non-point acupuncture group, acupuncture was delivered at non-points and all of the needles were retained for 30 min in these two groups. The samples were collected 24 h after reperfusion in the rats of each group. Zea-Longa neurological deficit score was used to evaluate the degree of cerebral neurological impairment, TTC staining was adopted to observe the volume percentage of cerebral infarction, HE staining was provided to observe the morphological changes of brain, and Western blot was applied for detecting the expression of HIF-1α and NLRP3 proteins in the cerebral cortex on the right side. RESULTS: Compared with the sham-operation group, neurological deficit score and volume percentage of cerebral infarction were increased in the model group (P<0.01), and HIF-1α and NLRP3 protein expression was elevated (P<0.01). Compared with the model group, neurological deficit score and volume percentage of cerebral infarction were decreased (P<0.01), and HIF-1α and NLRP3 protein expression was lower (P<0.01) in the acupuncture group. There was no significant difference in above indexes in the non-point acupuncture group compared with the model group (P>0.05). Compared with the sham-operation group, the brain tissue of the rats in the model group and the non-point acupuncture group was loose and edema, and the nuclei were shriveled. The brain tissue morphology in the acupuncture group was similar to that of the sham-operation group. CONCLUSION Acupuncture can alleviate cerebral ischemia-reperfusion injury, and its mechanism may be related to the regulation of HIF-1α/NLRP3 signaling pathway to attenuate inflammatory response.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Huosu Yangwei (HSYW) Formula is a traditioanl Chinese herbal medicine that has been extensively used to treat chronic atrophic gastritis, precancerous lesions of gastric cancer and advanced gastric cancer. However, the effective compounds of HSYW and its related anti-tumor mechanisms are not completely understood. In the current study, 160 ingredients of HSYW were identified and 64 effective compounds were screened by the ADMET evaluation. Furthermore, 64 effective compounds and 2579 potential targets were mapped based on public databases. Animal experiments demonstrated that HSYW significantly inhibited tumor growth in vivo. Transcriptional profiles revealed that 81 mRNAs were differentially expressed in HSYW-treated N87-bearing Balb/c mice. Network pharmacology and PPI network showed that 12 core genes acted as potential markers to evaluate the curative effects of HSYW. Bioinformatics and qRT-PCR results suggested that HSYW might regulate the mRNA expression of DNAJB4, CALD, AKR1C1, CST1, CASP1, PREX1, SOCS3 and PRDM1 against tumor growth in N87-bearing Balb/c mice.

As the body ages， the immune system will undergo a series of changes， which are termed "immunosenescence" and are embodied in immune cells. Previous studies have shown that the immune cells involved in the regulation of immunosenescence include intrinsic immune cells and adaptive immune cells. Intrinsic immune cells are neutrophils， monocytes/macrophages， myeloid-derived suppressor cells， dendritic cells， natural killer cells， etc.， and the underlying mechanisms involve the regulation of cell number， phagocytosis， chemotaxis， adhesion， the function of toll-like receptor （TLR）， antigen presentation， macrophage polarization， cytotoxicity， migration， etc. The adaptive immune cells include T-lymphocytes and B-lymphocytes， and the underlying mechanisms involve the regulation of cell development， proliferation， differentiation， cell number， telomerase activity， self-reactive antibodies， etc. Immunosenescence is the manifestation of aging in the human body and is also an important target for delaying aging by Chinese medicine and western medicine. In recent years， scholars have found some classical prescriptions and their active components （such as Dushentang and total saponins in Panax ginseng leaves， and Shengmaiyin and anwulignan and total saponins in P. ginseng stems and leaves） can regulate immunosenescence by targeting the immune cells and interfering with their molecular regulatory mechanisms. In addition， the mechanisms of the classical prescriptions in regulating immunosenescence are closely related to autophagy. The representative prescription embodying the therapeutic principles of resolving blood stasis and promoting regeneration， Dahuang Zhechongwan， can delay D-galactose-induced renal aging in mice， and its underlying mechanisms are related to the regulation of the number and activity of thymic immune cells and improvement of the protein expression of autophagy-related markers and inflammatory cytokines in the kidney. Therefore， exploring the effects of the classical prescriptions and their active components by targeting the mechanisms of immunosenescence will become a new direction for investigating and developing anti-aging drugs.

Objective:To investigate the protective effect of Naoxin'an capsule （NC） against glial cell activation and inflammatory damage in brain of rats with chronic cerebral hypoperfusion-induced vascular cognitive impairment （VCI）. Method:One hundred and fifty rats were randomly divided into a sham operation group （n=20） and a modeling group （n=130）. Following the modeling with the two vessels occlusion （2-VO） technique， 87 successfully modeled rats were randomly divided into the model group， positive drug group （aricept， 0.5 mg·kg^-1）， and low-， medium-， and high-dose （0.18， 0.36， 0.72 g·kg^-1） NC groups， with 17-18 rats in each group. After intragastric administration of NC for eight weeks， the Morris water maze test and passive avoidance test were conducted to detect the effects of NC on learning and memory ability of VCI rats. Changes in neuronal structure of rat hippocampal CA1 area were observed by hematoxylin-eosin （HE） staining， and the neuronal apoptosis in hippocampus by terminal deoxynucleotidyl transferase （TdT）-mediated dUTP nick end labeling （TUNEL） staining. Western blot assay was used to detect the expression levels of glial fibrillary acidic protein （GFAP）， ionized calcium-binding adapter molecule 1 （Iba-1）， phosphorylated p38 mitogen-activated protein kinase （p38 MAPK）， and phosphorylated nuclear factor κB （NF-κB）， followed by the measurement of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the brain by enzyme-linked immunosorbent assay （ELISA）. Result:Compared with the sham operation group， the model group displayed obviously decreased spatial learning and memory ability and memory retention ability （P<0.05， P<0.01）， neuronal damage in hippocampal CA1 area， enhanced neuronal apoptosis （P<0.01）， up-regulated GFAP and Iba-1 （P<0.01）， elevated phosphorylation of p38 MAPK and NF-κB （P<0.01）， and increased IL-1β and TNF-α （P<0.01）. Compared with the model group， NC at each dose significantly improved the spatial learning and memory ability and memory retention ability of VCI rats （P<0.05， P<0.01）， ameliorated the neuronal damage in hippocampus CA1 area， reduced the apoptosis rate of nerve cells （P<0.05， P<0.01）， down-regulated the expression of GFAP and Iba-1 （P<0.01）， decreased the phosphorylation levels of p38 MAPK and NF-κB （P<0.05， P<0.01）， and lowered TNF-α and IL-1β levels （P<0.01）. Conclusion:NC alleviates the inflammatory damage of the central nervous system caused by activated p38 MAPK and NF-κB and improves chronic cerebral hypoperfusion-induced VCI in rats by inhibiting the activation of microglia and astrocytes.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).
