ObjectiveTo investigate whether Jiedu Huoxue prescription can induce macrophage autophagy and inhibit inflammatory response to stabilize vulnerable plaques of atherosclerosis (AS) by regulating phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodThirty ApoE-/- mice fed with high-fat diet were randomly assigned into model, low-, medium-, and high-dose (5.35, 10.7, and 21.4 g·kg-1·d-1, respectively) Jiedu Huoxue prescription (Chinese medicine), and rapamycin (2 mg·kg-1·d-1) groups. Six ApoE-/- mice fed with common diet were used as the control group, and 6 C57BL/6J mice fed with common diet as the blank group. The drugs or equal volume of normal saline were administrated by gavage after 7 weeks of modeling, and the treatment lasted for 4 weeks. The serum levels of lipids and inflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1) and interleukin-6 (IL-6)] were measured. Hematoxylin-eosin (HE) staining was employed to observe the pathological changes of the vascular wall of the aortic root. Immunohistochemistry was employed to detect the expression of macrophages/monocytes monoclonal antibody (MOMA-2) and α-smooth muscle actin (α-SMA). Transmission electron microscopy was employed to count the autophagosomes in the aorta, and Western blot to determine the protein levels of Beclin-1, LC3, PI3K, Akt, and mTOR. ResultCompared with the control group, the model group showed elevated serum levels of lipids, MCP-1, and IL-6 (P<0.05), inhibited expression of MOMA-2 and α-SMA (P<0.05, P<0.01), up-regulated protein level of Beclin-1 (P<0.05), and down-regulated protein levels of PI3K, Akt, and mTOR (P<0.05, P<0.01). The model group presented obvious atherosclerotic plaques on the inner wall of the aorta, infiltration of inflammatory cells in the plaque, thickened and disarranged vascular intima where the plaque was attached, decreased autophagosomes and mitochondria, and destroyed mitochondrial structure. Chinese medicine and rapamycin groups showed lower levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, MCP-1, and IL-6 (P<0.05), higher level of high-density lipoprotein cholesterol (P<0.05), inhibited expression of MOMA-2 and α-SMA (P<0.05, P<0.01), higher protein levels of Beclin-1 and LC3Ⅱ (P<0.05, P<0.01), and lower protein levels of PI3K, Akt, and mTOR (P<0.05, P<0.01) than the model group. Moreover, Chinese medicine and rapamycin groups showed only a small number of atherosclerotic plaques on the inner wall of the aorta, reduced infiltration of inflammatory cells and thickness of the blood vessel wall, and increased autophagosomes and autophagic lysosomes. ConclusionJiedu Huoxue prescription can improve lipid metabolism, enhance macrophage autophagy, and reduce AS-induced inflammation to improve the stability of vulnerable plaques in AS mice by inhibiting the PI3K/Akt/mTOR signaling pathway.

The paper explores the evolution of "bone-approaching" acupuncture, its effect target and mechanism. The concrete operation procedure of "bone-approaching" method is recorded originally in Huangdi Neijing (Inner Canon of Yellow Emperor) as short needling and Shu needling (referring to the category of the five needling technique). The periosteum is the most effective stimulation target of "bone-approaching" acupuncture for analgesia, regaining consciousness and regulating spirit. The "bone-approaching" acupuncture is not only prominently effective on bone bi syndrome, but also has the unique effect on painful, encephalogenic and emotional diseases. The paper summarizes and improves "bone-approaching" acupuncture, i.e. "touching bone surface" with needle tip by slow insertion, "touching bone surface" without pain by swift insertion and "touching bone" with needle body by oblique insertion. It contributes to the inheritance, development and supplementation to the bone needling techniques in Huangdi Neijing and is significant for broadening the clinical application range of acupuncture.

The ribose and phosphorus contents in Haemophilus influenzae type b (Hib) capsular polysaccharide (CPS) are two important chemical indexes for the development and quality control of Hib conjugate vaccine. A quantitative 1H- and 31P-NMR method using a single internal standard was developed for simultaneous determination of ribose and phosphorus contents in Hib CPS. Hexamethylphosphoramide (HMPA) was successfully utilized as an internal standard in quantitative 1H-NMR method for ribose content determination. The ribose and phosphorus contents were found to be affected by the concentration of polysaccharide solution. Thus, 15-20 mg·L-1 was the optimal concentration range of Hib CPS in D2O solution for determination of ribose and phosphorus contents by this method. The ribose and phosphorus contents obtained by the quantitative NMR were consistent with those obtained by traditional chemical methods. In conclusion, this quantitative 1H- and 31P-NMR method using a single internal standard shows good specificity, accuracy and precision, providing a valuable approach for the quality control of Hib glycoconjugate vaccines.

Objective: To compare the therapeutic efficacy of Han-uvulopalatopharyngoplasty (HUPPP) combined with radiofrequency ablation of tongue base or HUPPP with traction of tongue base on moderate to severe patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: This is a multicenter randomized controlled trial. From March 2017 to July 2019, moderate to severe OSAHS patients from three clinical center in Shanghai who were intolerant to continuous positive airway pressure (CPAP) and with velopharyngeal and glossopharyngeal plane obstruction were enrolled in this study. According to the surgical type, they were 1∶1 randomized to HUPPP plus radiofrequency ablation of tongue base group (Ablation group) or HUPPP plus traction of tongue base group (Traction group). All patients completed over-night standard Polysomnography (PSG), upper-airway assessment (Friedman classification, Müller test, CT and cephalometric examination), preoperative routine examination, Epworth Sleepiness Scale (ESS) and Quebec sleep questionnaire (QSQ). Six to 12 months after operation, all the above-mentioned examinations were repeatedly performed. Changes of aforementioned variables before and after operation were assessed. Results: A total of 43 patients with moderate to severe OSAHS were enrolled in this study. One patient lost to follow-up, the remaining 21 were allocated to Ablation group and 21 were allocated to Traction group. The total therapeutic efficacy of all patients was 69.05% (61.90% in Ablation group and 76.19% in Traction group), but there was no statistical significance between the two groups (P= 0.317). The value of sleep scale score (ESS and QSQ), objective sleep variables (apnea-hypopnea index, oxygen saturation, percentage of time with blood oxygen less than 90% in total sleep time, oxygen desaturation index and micro-arousals) and upper airway cross-sectional area (palatopharyngeal and retrolingual area) of the two groups were improved (P<0.05), but the differences between the two groups were not statistically significant (P>0.05). Conclusion: For moderate to severe OSAHS who had glossopharyngeal plane obstruction, both HUPPP plus radiofrequency ablation of tongue base or HUPPP plus traction of tongue base are effective treatment for OSAHS, and the curative effect is similar. The choice of surgical type could be selected according to patient's or surgical conditions.

INTRODUCTIONHepatitis B virus (HBV) reactivation has been reported in B-cell lymphoma patients with resolved hepatitis B (hepatitis B surface antigen [HBsAg]-negative and hepatitis B core antibody [HBcAb]-positive). This study aimed to assess HBV reactivation and hepatitis occurrence in diffuse large B-cell lymphoma (DLBCL) patients with resolved hepatitis B receiving rituximab-containing chemotherapy compared with HBsAg-negative/HBcAb-negative patients to identify risk factors for HBV reactivation and hepatitis occurrence and to analyze whether HBV reactivation and hepatitis affect the survival of DLBCL patients with resolved hepatitis B.
METHODSWe reviewed the clinical data of 278 patients with DLBCL treated with rituximab-containing therapy between January 2004 and May 2008 at Sun Yat-sen University Cancer Center, China. Predictive factors for HBV reactivation, hepatitis development, and survival were examined by univariate analysis using the chi-square or Fisher's exact test and by multivariate analysis using the Cox regression model.
RESULTSAmong the 278 patients, 165 were HBsAg-negative. Among these 165 patients, 6 (10.9%) of 55 HBcAb-positive (resolved HBV infection) patients experienced HBV reactivation compared with none (0%) of 110 HBcAb-negative patients (P = 0.001). Patients with resolved hepatitis B had a higher hepatitis occurrence rate than HBsAg-negative/HBcAb-negative patients (21.8% vs. 8.2%, P = 0.013). HBcAb positivity and elevated baseline alanine aminotransferase (ALT) levels were independent risk factors for hepatitis. Among the 55 patients with resolved hepatitis B, patients with elevated baseline serum ALT or aspartate aminotransferase (AST) levels were more likely to develop hepatitis than those with normal serum ALT or AST levels (P = 0.037, P = 0.005, respectively). An elevated baseline AST level was an independent risk factor for hepatitis in these patients. Six patients with HBV reactivation recovered after immediate antiviral therapy, and chemotherapy was continued. HBcAb positivity, HBV reactivation, or hepatitis did not negatively affect the survival of DLBCL patients.
CONCLUSIONSDLBCL patients with resolved hepatitis B may have a higher risk of developing HBV reactivation and hepatitis than HBsAg-negative/HBcAb-negative patients. Close monitoring and prompt antiviral therapy are required in these patients.

Gap junctions play a critical role in electrical synchronization and exchange of small molecules between neighboring cells; connexins are a family of structurally related transmembrane proteins that assemble to form vertebrate gap junctions. Hyperglycemia changes the structure gap junction proteins and their expression, resulting in obstruction of neural regeneration, vascular function and wound healing, and also promoting vascular atherosclerosis. These pathogenic factors would cause diabetic foot ulcers. This article reviews the involvement of connexins in pathogenesis of diabetic foot.
