Exploration on acupuncture treatment ideas for knee osteoarthritis from the perspective of Dongyuan needling technology / 中国针灸

The treatment ideas with acupuncture for knee osteoarthritis (KOA) are explored on the base of Dongyuan needling technology. Regarding the rules of acupoint selection, Zusanli (ST 36) is predominant, the back-shu points are used for the disorders related to the invasion of exogenous factors, and the front-mu points are for the cases caused by internal injury. Besides, the xing-spring points and shu-stream points are preferred. In treatment of KOA, besides the local points, the front-mu points, i.e. Zhongwan (CV 12), Tianshu (ST 25) and Guanyuan (CV 4), are selected specially to tonifying the spleen and stomach. The earth points and acupoints on the earth meridians (i.e. Yinlingquan [SP 9], Xuehai [SP 10], Liangqiu [ST 34], Dubi [ST 35], Zusanli [ST 36] and Yanglingquan [GB 34]) are optional to coordinate yin and yang, essence and qi , and regulate the qi movement of spleen and stomach. The shu-stream points of liver, spleen and kidney meridians (Taichong [LR 3], Taibai [SP 3] and Taixi [KI 3]) are chosen to promote meridian circulation and regulate zangfu functions.

Chronic spontaneous urticaria treated with bloodletting therapy and auricular point sticking on the base of xuanfu theory: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical therapeutic effect and the impacts on recurrence rate on chronic spontaneous urticaria (CSU) between the combined treatment of bloodletting therapy and auricular point sticking on the base of xuanfu theory and the oral solution of levocetirizine hydrochloride.@*METHODS@#A total of 86 patients with CSU were randomized into an observation group (43 cases, 1 case dropped off) and a control group (43 cases, 3 cases dropped off). In the observation group, bloodletting therapy at Dazhui (GV 14), Feishu (BL 13), Geshu (BL 17) and Pishu (BL 20) was combined with auricular point sticking at lung (CO14), kidney (CO10), shenmen (TF4) and heart (CO15), etc. This combined treatment was given once every two days. In the control group, the oral solution of levocetirizine hydrochloride was prescribed, 10 mL each time, once daily. The treatment lasted for 4 weeks in the two groups. Before and after treatment, urticaria activity score 7 (UAS7), the score of dermatology life quality index (DLQI) and the levels of serum immune globulin E (IgE), interleukin 4 (IL-4) and interferon γ (IFN-γ) were compared in the patients between the two groups. The clinical therapeutic effect was evaluated in patients of the two groups and the recurrence rate was followed up 4, 8 and 12 weeks after treatment separately.@*RESULTS@#After treatment, the scores of UAS7 and DLQI, as well as the levels of serum IgE and IL-4 were all reduced as compared with those before treatment in the two groups (P<0.05), and the level of serum IFN-γ was increased (P<0.05). The total effective rate was 83.3% (35/42) in the observation group and was 85.0% (34/40) in the control group. There was no statistical significance for the difference in the clinical therapeutic effect between the two groups (P>0.05). Eight and 12 weeks after treatment, the recurrence rates were 21.1% (4/19) and 26.3% (5/19) in the observation group, lower than 55.0% (11/20) and 65.0% (13/20) in the control group, respectively (P<0.05).@*CONCLUSION@#The combined therapy of bloodletting and auricular point sticking on the base of xuanfu theory relieves the clinical symptoms, regulates the levels of serum IgE, IL-4 and IFN-γ and improves the quality of life in the patients with CSU. The clinical therapeutic effect of this combined treatment is similar to the oral solution of levocetirizine hydrochloride. But, the recurrence rate of the combined treatment of bloodletting and auricular point sticking is lower and its long-term curative effect is better.

Expert Consensus on Otorhinolaryngology Head and Neck Diseases Responding Specifically to Traditional Chinese Medicine / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） and western medicine have their respective advantages and limitations in the diagnosis and treatment of common otorhinolaryngology head and neck diseases. Although the integrated TCM and western medicine exhibits definite curative effects， there is no consensus on the otorhinolaryngology head and neck diseases responding specifically to TCM or integrated TCM and western medicine， as well as the diagnosis and treatment schemes. The China Association of Chinese Medicine （CACM） thus organized the otorhinolaryngology head and neck specialists of both TCM and western medicine to discuss the etiology， pathogenesis， and clinical diagnosis and treatment methods of common otorhinolaryngology head and neck diseases with the results of multiple clinical trials taken into account. The acute pharyngitis， chronic pharyngolaryngitis， paraesthesia pharyngis， hysterical aphasia， allergic rhinitis， subjective tinnitus， and otogenic vertigo were confirmed to respond specifically to TCM or integrated TCM and western medicine. Then a mutually agreed diagnosis and treatment scheme and recommendation with integrated TCM and western medicine was formulated as a reference for clinical practice， thus benefiting more patients.

Salivary Pepsin as an Intrinsic Marker for Diagnosis of Sub-types of Gastroesophageal Reflux Disease and Gastroesophageal Reflux Disease-related Disorders

Background/Aims@#To determine the value of salivary pepsin in discriminating sub-types of gastroesophageal reflux disease (GERD) and GERD-related disorders. @*Methods@#Overall, 322 patients with different sub-types of GERD and 45 healthy controls (HC) were studied. All patients took Gastroesophageal Reflux Disease Questionnaire (GerdQ) and underwent endoscopy and 24-hour esophageal pH monitoring and manometry. Salivary pepsin concentration (SPC) was detected by using colloidal gold double-antibody immunological sandwich assay. Oral esomeprazole treatment was administrated in the patients with non-erosive reflux disease (NERD) and extra-esophageal symptoms (EES). @*Results@#Compared to HC, patients with erosive esophagitis, NERD, EES, EES plus typical GERD symptoms, or Barrett’s esophagus had a higher prevalence of saliva and SPC (all P < 0.001). There was no significant difference in the positive rate for pepsin in patients with functional heartburn or GERD with anxiety and depression, compared to HC. After esomeprazole treatment, the positive rate and SPC were significantly reduced in NERD (both P < 0.001) and in EES (P = 0.001 and P = 0.002, respectively). Of the 64 NERD patients, 71.9% (n = 46) were positive for salivary pepsin, which was significantly higher than the rate (43.8%, n = 28) of pathological acid reflux as detected by 24-hour esophageal pH monitoring (P = 0.002). @*Conclusions@#Salivary pepsin has an important significance for the diagnosis of GERD and GERD-related disorders. Salivary pepsin and 24-hour esophageal pH monitoring may complement with each other to improve the diagnostic efficiency.

Divergent effects of lycopene on pancreatic alpha and beta cells / 生理学报

Lycopene is an antioxidant which has potential anti-diabetic activity, but the cellular mechanisms have not been clarified. In this study, different concentrations of lycopene were used to treat pancreatic alpha and beta cell lines, and the changes of cell growth, cell apoptosis, cell cycle, reactive oxygen species (ROS), ATP levels and expression of related cytokines were determined. The results exhibited that lycopene did not affect cell growth, cell apoptosis, cell cycle, ROS and ATP levels of alpha cells, while it promoted the growth of beta cells, increased the ratio of S phase, reduced the ROS levels and increased the ATP levels of beta cells. At the same time, lycopene treatment elevated the mRNA expression levels of tnfα, tgfβ and hif1α in beta cells. These findings suggest that lycopene plays cell-specific role and activates pancreatic beta cells, supporting its application in diabetes therapy.

OBJECTIVE@#To compare the infuences on circadian rhythm of blood pressure in the patients with non-dipper essential hypertension between the combined treatment of time acupuncture and western medication and the simple western medication.@*METHODS@#A total of 70 patients with non-dipper essential hypertension were randomized into an acupuncture plus western medication group (35 cases, 2 cases dropped out) and a western medication group (35 cases). In the western medication group, levamlodipine maleate tablets were taken orally, 2.5 mg each time, once daily. In the acupuncture plus western medication group, on the base of the treatment as the western medication group, acupuncture was applied specially in the period of the day from 7:00 am to 9:00 am. The acupoints included Fengchi (GB 20), Zhongwan (CV 12), Tianshu (ST 25), Hegu (LI 4), Quchi (LI 11), Zusanli (ST 36), etc. Acupuncture was given once daily, 5 treatments a week. The duration of treatment in the two groups was 4 weeks. The clinic blood pressure before and after treatment, 24 h ambulatory blood pressure and the levels of serum melatonin (MT) and 5-serotonin (5-HT) were observed in the two groups.@*RESULTS@#The total effective rate of anti-hypertension was 75.8% (25/33) in the acupuncture plus western medication group, better than 54.3% (19/35) in the western medication group (<0.05). The 24 h average systolic blood pressure, the daytime average systolic blood pressure, the daytime average diastolic pressure, and the nighttime average systolic blood pressure were all reduced after treatment in the two groups (<0.05). The reduction effect of the aforementioned 4 indexes in the acupuncture plus western medication group was much more obvious as compared with the western medication group (<0.05). After treatment, the serum level of MT was increased and 5-HT decreased in the patients of two groups (<0.05). The serum level of MT in the acupuncture plus western medication group was higher than that in the western medication group and the level of 5-HT was lower than the western medication group (<0.05).@*CONCLUSION@#Time acupuncture therapy in the period of the day from 7:00 am to 9:00 am, combined with western medication effectively reduce blood pressure and regulate the levels of serum MT and 5-HT so as to maintain the circadian rhythm of blood pressure in patients with non-dipper essential hypertension. The therapeutic effect of this combined treatment is superior to simple western medication.

Effect of Traditional Chinese Medicine in Regulating Immune Mechanism of Chronic Urticaria / 中国实验方剂学杂志

Chronic urticaria (CU) is one of common diseases of dermatology. It has the clinical characteristics of allergy, multiple, recurrent and persistent recovery. The clinical symptoms of patients are mainly pruritus and wheal, and concurrent with vascular edema, some patients may even suffer from chest tightness, nausea and other systemic symptoms. Its pathogenesis is still unclear, and it is generally considered to be related to autoimmune, chronic infection, coagulation mechanism, vitamin D deficiency and so on. Among them, autoimmunity may be one of the important causes for chronic urticaria. Clinical studies mostly focus on immunoglobulin E, T cell subsets CD4+ T cells, CD8+ T cells, cytokines interleukin-2, interferon-γ, and complement C3, C4. Western medicine therapies mostly use antihistamines. The first generation of antihistamines have an obvious inhibitory effect on central nervous system, and side reactions, such as sedative and anticholinergic Effect. Although the second generation has a reduced inhibitory effect on central nervous system, it is easy to cause heart toxicity and relapse after drug withdrawal. Therefore, it is particularly important to find a safe and effective traditional Chinese medicine(TCM) therapy. Urticaria belongs to the category of " hidden rashes" in TCM. The etiology and pathogenesis are insufficient endowment of body elements, insufficient external defense or improper diet, damp-heat connotation. Classic prescriptions and self-prepared formulas, such as Jade Screen Powder, shall be used in the treatment of phlegm and blood stasis, with a clear clinical effect and a low recurrence rate. In addition, by reducing the level of immunoglobulin E in patients, improving CD4+ T cells, CD8+ T cell levels, regulating the levels of related cytokines, increasing the levels of complement C3, C4, these therapies could reduce IgE levels, release of anaphylatoxins, stimulation of mast cells and inflammatory reactions, and regulate the body' s immune function, with a satisfactory efficacy. Therefore, the author has summarized the clinical researches on the mechanism of traditional Chinese medicine in regulating chronic urticaria in past five years.

Effects of IL-17 on expression of GRO-α and IL-8 in fibroblasts from nasal polyps / 华中科技大学学报（医学）（英德文版）

Recent studies indicated that interleukin (IL)-17, growth-related oncogene (GRO)-α and IL-8 play an important role in the pathogenesis of nasal polyps. However, the effects of the increased amount of IL-17 and the production of GRO-α and IL-8 in human nasal polyp fibroblasts are not completely understood. This study aimed to determine the effects of the increased IL-17 on the changes of GRO-α and IL-8 expression in human nasal polyp fibroblasts and further investigate the mechanism of neutrophil infiltration in nasal polyps. Nasal polyp fibroblasts were isolated from six cases of human nasal polyps, and the cells were stimulated with five different concentrations of IL-17. Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of GRO-α and IL-8. The mRNA of GRO-α and IL-8 was expressed in unstimulated controls and remarkably increased by stimulation with IL-17. Moreover, the levels of GRO-α and IL-8 produced by fibroblasts were increased gradually with the increases in IL-17 concentrations. The present study showed that nasal fibroblasts can produce GRO-α and IL-8, and their production is remarkably enhanced by IL-17 stimulation, thereby clarifying the mechanism of the IL-17 mediated neutrophil infiltration in nasal polyps. These findings might provide a rationale for using IL-17 inhibitors as a treatment for nasal inflammatory diseases such as nasal polyps.

Lung function parameters, eosinophil counts in induced sputum, concentration of exhaled nitric oxide and the Asthma Control Test scores were recorded, at regular intervals in the follow-up period. Twenty-one healthy volunteers were enrolled as control group and underwent examination of eosinophil counts in induced sputum, lung function and concentration of exhaled nitric oxide.</p><p><b>RESULTS</b>Sixty-three subjects from treatment group completed follow-up period for one year or longer. Mean FEV(1) value of the 63 subjects was (2.75 ± 0.54) L at baseline, (2.97 ± 0.56) L and (3.07 ± 0.52) L at month 3 and month 6, respectively, and maintained as (3.14 ± 0.51) L in the following six months. Mean FENO decreased from (61 ± 25) parts per billion (ppb) at baseline to (32 ± 19) ppb at month 3 (P < 0.05), and continued to decrease to (22 ± 12) ppb at month 6, the difference being significant when compared to both baseline and control group ((13 ± 8) ppb). Mean eosinophil counts decreased to (0.032 ± 0.011) × 10(6)/ml at month 3, which was significantly different from baseline ((0.093 ± 0.023)×10(6)/ml) and the control group ((0.005 ± 0.003)×10(6)/ml (both P < 0.05). The eosinophil counts in induced sputum correlated positively with concentration of FENO in the first six months (all P < 0.05). The concentration of FENO had a significant negative correlation with FEV(1) value (all P < 0.05) in any time point in the follow-up period. The Asthma Control Test scores were 18 ± 5, 19 ± 7, 23 ± 2, 24 ± 1 and 24 ± 1 at months 1, 3, 6, 9 and 12, respectively, which were significantly different from the score at baseline (14 ± 3) (P < 0.05). The most rapid clinical effect was observed at the second month after treatment.</p><p><b>CONCLUSION</b>Eosinophil counts in induced sputum and FENO are sensitive parameters to detect airway inflammation and may be useful in evaluating the efficacy of treatment and adjusting medication regimens.</p>
