Clinical practice guideline for acupuncture and moxibustion: Allergic rhinitis.

Acupuncture is one of the most effective complementary therapies for allergic rhinitis (AR) and has been recommended by several clinical practice guidelines (CPGs) for AR. However, these CPGs mentioned acupuncture without making recommendations for clinical implementation and therapeutic protocols, therefore limiting the applicability of acupuncture therapies for AR. Hence, for the benefit of acupuncture practitioners around the world, the World Federation of Acupuncture-moxibustion Societies have initiated a project to develop the CPG for the use of acupuncture and moxibustion to treat AR. This CPG was developed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, referring to the principles of the World Health Organization Handbook for Guideline Development. During the development of the CPG, the guideline development group (GDG) played an important role. The clinical questions, recommendations and therapeutic protocols were all formulated by the GDG using the modified Delphi method. The CPG contains recommendations for 15 clinical questions about the use of acupuncture and moxibustion interventions. These include one strong recommendation for the intervention based on high-quality evidence, three conditional recommendations for either the intervention or standard care, and 11 conditional recommendations for the intervention based on very low quality of evidence. The CPG also provides one filiform needle acupuncture protocol and five moxibustion protocols extracted based on the protocols presented in randomized controlled trials reviewed by the GDG.

[Regularity of meridian-acupoint reactions of foot three yin meridians in primary dysmenorrhea and secondary dysmenorrhea patients].

OBJECTIVE: To observe the meridian-acupoint reactions of foot three yin meridians in primary dysmenorrhea(PD) and secondary dysmenorrhea(SD) patients, so as to summarize the rules of meridian-acupoint reaction and acupoints selection. METHODS: Thirty-five patients with PD (PD group), 34 patients with SD (SD group) and 35 healthy subjects (healthy group) were recruited. The compression method was used to examine the lower leg segment of the foot three yin meridians. Positive reactions(palpable skin changes, including cords, nodules, depressions) and tenderness of meridians and acupoints were recorded. The visual analogue scale (VAS) was used to evaluate the tenderness severity of acupoints. RESULTS: Compared with the healthy group, the probability of positive reactions and tenderness in foot three yin meridians were higher in PD and SD groups (P<0.01,P<0.05). Compared with the PD group, the probability of positive reactions in Spleen and Liver Meridians were higher in the SD group, with higher probability of tenderness in Liver Meridian(P<0.05). The probability of positive reactions and tenderness in the Spleen Meridian of PD and SD groups was significantly higher than that in the Kidney Meridian (P<0.01), while the probability of tenderness in the Spleen Meridian of the PD group was significantly higher than that in the Liver Meridian (P<0.05). Positive reactions and tenderness were concentrated at Yinlingquan (SP9), Diji (SP8) and Sanyinjiao (SP6) of Spleen Meridian and Xiguan (LR7) and Ligou (LR5) in Liver Meridian of PD and SD groups. In comparison with the PD group, the probability of positive reactions, tenderness and VAS score of SP8 and LR5 of the SD group were higher (P<0.05, P<0.01). CONCLUSION: The positive reaction occurs most frequently in the Spleen Meridian, followed by the Liver Meridian, and least frequently in the Kidney Meridian. The acupoints with positive reaction are different between PD and SD, which suggests that the Spleen Meridian acupoints should be the main acupoints when treating the two kinds of dysmenorrhea, and acupoints should also be selected according to the meridian and acupoint examination results.

Overexpression of LaGRAS enhances phosphorus acquisition via increased root growth of phosphorus-deficient white lupin.

The GRAS transcription factors play an indispensable role in plant growth and responses to environmental stresses. The GRAS gene family has extensively been explored in various plant species; however, the comprehensive investigation of GRAS genes in white lupin remains insufficient. In this study, bioinformatics analysis of white lupin genome revealed 51 LaGRAS genes distributed into 10 distinct phylogenetic clades. Gene structure analyses revealed that LaGRAS proteins were considerably conserved among the same subfamilies. Notably, 25 segmental duplications and a single tandem duplication showed that segmental duplication was the major driving force for the expansion of GRAS genes in white lupin. Moreover, LaGRAS genes exhibited preferential expression in young cluster root and mature cluster roots and may play key roles in nutrient acquisition, particularly phosphorus (P). To validate this, RT-qPCR analysis of white lupin plants grown under +P (normal P) and -P (P deficiency) conditions elucidated significant differences in the transcript level of GRAS genes. Among them, LaGRAS38 and LaGRAS39 were identified as potential candidates with induced expression in MCR under -P. Additionally, white lupin transgenic hairy root overexpressing OE-LaGRAS38 and OE-LaGRAS39 showed increased root growth, and P concentration in root and leaf compared to those with empty vector control, suggesting their role in P acquisition. We believe this comprehensive analysis of GRAS members in white lupin is a first step in exploring their role in the regulation of root growth, tissue development, and ultimately improving P use efficiency in legume crops under natural environments.

[Application of meridian and acupoint diagnosis of three yin meridians of foot in the treatment for gynecological diseases with acupuncture and moxibustion].

With three representative types of gynecological diseases (dysmenorrhea, pelvic inflammation, polycystic ovary syndrome) as examples, the application methods of meridian and acupoint diagnosis for gynecological diseases treated with acupuncture and moxibustion are discussed. During clinical diagnosis and treatment, it is recommended to examine the patient's leg segment along the three yin meridians of foot, aiming to explore the positive reactions of the meridians and acupoints (color, shape, skin temperature, sensory abnormalities, etc.). Acupuncture and moxibustion treatment at this positive reaction place can improve the clinical efficacy. Meridian and acupoint diagnosis could provide basis for meridian syndrome differentiation, thus guiding the selection of acupoint prescriptions; it is also helpful to clarify the deficiency, excess, cold and heat of the disease nature, thus guiding the selection of acupuncture and moxibustion methods. In addition, it is an auxiliary method to estimate the prognosis and outcome of the disease.

[Acupuncture for secondary dysmenorrhea of adenomyosis: a prospective case-series study].

OBJECTIVE: To observe the clinical effect of acupuncture by stages on secondary dysmenorrhea of adenomyosis through prospective case-series study. METHODS: A total of 36 cases of adenomyosis patients with moderate-to-severe dysmenorrhea were treated with acupuncture by stages. The acupoints of Diji (SP 8), Sanyinjiao (SP 6), Ciliao (BL 32) and Shiqizhui (EX-B 8) were selected and acupuncture was given once a day during menstrual period; the acupoints of Guanyuan (CV 4), Zigong (EX-CA1), Sanyinjiao (SP 6) and Zusanli (ST 36) ect. were selected and acupuncture was given twice per week during non-menstrual period. All the treatment was given for three menstrual cycles. The visual analogue scale (VAS), Cox menstrual symptom scale (CMSS), Endometriosis Health Profile-5 (EHP-5) scores and the menstrual blood volume of pictorial blood loss assessment chart (PBAC) were observed before treatment and at the 1st, 2nd and 3rd menstrual cycle into treatment. Before treatment and at the 3rd menstrual cycle into treatment, the volume of uterus was measured by transvaginal ultrasound and the correlation among the quality of life, the severity of pain and symptoms was analyzed. RESULTS: The VAS, CMSS and EHP-5 scores at the 1st, 2nd and 3rd menstrual cycle into treatment were lower than those before treatment (P<0.01, P<0.05), and the PBAC scores were reduced but without statistical different (P>0.05). Compared before treatment, at the 1st, 2nd and 3rd menstrual cycle into treatment, the PBAC scores were reduced in patients with PBAC>100 points (P<0.01). Compared between 2nd and 1st menstrual cycle into treatment, between 3rd and 2nd menstrual cycle into treatment, the VAS, CMSS scores were all decreased (P<0.01, P<0.05). There was a significant positive correlation between the severity score of CMSS and EHP-5 at the corresponding time points of the 1st, 2nd and 3rd menstrual cycle into treatment (P<0.01). CONCLUSION: The acupuncture by stages has significant analgesic effect in patients with secondary dysmenorrhea of adenomyosis, and has the advantages of relieving the menstruation-related symptoms, regulating menstrual blood volume and improving the quality of life.

A wetland plant, Phalaris arundinacea, accumulates nitrogen and phosphorus during senescence.

Secondary pollution resulting from shoot death is a difficult problem that complicated the application of wetland plants for water purification in northern wetlands. Phalaris arundinacea, a perennial herb with an obviously declining stage, or senescence, is a species that is often selected for water purification in Northern China; however, whether it reduces the secondary pollution risk via nitrogen (N) and phosphorus (P) accumulation during senescence or not remains unclear. To investigate this question, an experiment was conducted with containerized plants during the winter of 2016, after roughly half the leaves on the plants had withered. The experimental observations and analyses were conducted within 0, 2, 4, 6, and 8 weeks of the initiation of senescence. Results revealed that leaves continued to wither and shoot death occurred during weeks 4 to 6 and 8 to 10, respectively. However, no significant differences occurred in fresh biomass or in N and P accumulations of a single plant during senescence. The root biomass, root weight per volume, and total N content increased significantly, while total P content remained stable when leaves withered, respectively. H+-ATPase, a key enzyme for ion transportation, decreased after the leaves withered. However, root activity, evaluated by absorption surface per root volume, remained stable, and percentage of fine root length (diameter < 1 mm) increased significantly during senescence. In conclusion, the root activity and morphology enables P. arundinacea to accumulate N and P during senescence, which makes it a good choice for water purification in northern wetlands.

Treatment of gastric precancerous lesions with Weiansan.

AIM: To observe the curative effect of Weiansan (WAS) on gastric precancerous lesions (GPL) and H pylori elimination. METHODS: Seventy-six patients with GPL were randomly divided into two groups: WAS group (n = 42) and Weifuchun (WFC) group (n = 34). The patients in the WAS group were administered 5 g WAS 3 times a day, and the patients in the WFC group took WFC (4 tablets) 3 times a day. To monitor inflammation of gastric mucosa, degree of glandular atrophy (GA), intestinal metaplasia (IM) and dysplasia, and H pylori infection, all patients underwent gastroscopy and biopsy with pathological examination before and after treatment. Fifty male Sprague-Dawley (SD) rats were used in animal experiments. Of these, 10 served as the control group (n = 10), 40 were given ranitidine combined with N-methyl-N(1)-nitro-N-nitrosoguanidine (MNNG) for 12 wk and divided into 4 groups randomly: model group (n = 10), high-dose WAS group (n = 10), low-dose WAS group (n = 10) and WFC group (n = 10). Twelve weeks later, all rats were killed and a 2 cm multiply 1 cm tissue was taken from the lesser curvature of the gastric antrum. H pylori infection was determined by the fast urease method. RESULTS: The curative effect in WAS groups was similar to that in WFC groups. There was no statistical difference in degree of GA, IM and dysplasia between WAS and WFC groups. The rate of H pylori infection in the model group (positive/negative: 9/1) was significantly higher than that in the control group (positive/negative: 1/9) (P < 0.01). H pylori elimination in the high-dose WAS group (positive/negative: 4/6) and low-dose WAS group (positive/negative: 6/4) was similar to that in the WFC group (positive/negative: 4/6) (P > 0.05). CONCLUSION: WAS improves clinical symptoms by suppressing GA, IM and dysplasia and eliminating H pylori.
