Objective To investigate the clinical efficacy of acupuncture plus Chinese herbal medicine in treating allergic rhinitis. Methods One hundred and thirty-five patients with allergic rhinitis were randomly allocated to combination, acupuncture and Chinese herbal medicine groups, 45 cases each. The combination group received treatment with acupuncture plus Chinese herbal medicine; the acupuncture group, treatment with acupuncture alone; the Chinese herbal medicine group, treatment with Chinese herbal medicine alone. IgE, IL-4, IL-5 and TNF-αlevels and clinical symptom and sign total score were observed in the three groups before and after treatment. The clinical therapeutic effects were compared between the three groups. Results There were statistically significant pre-/post-treatment differences in IL-4, IL-5, TNF-αand IgE levels in the three groups (P<0.05). There were statistically significant post-treatment differences in IL-4, IL-5 and IgE levels between the combination group and the Chinese herbal medicine or acupuncture group (P<0.05). There was a statistically significant pre-/post-treatment difference in clinical symptom and sign total score in the three groups (P<0.05). There was a statistically significant post-treatment difference in clinical symptom and sign total score between the combination group and the Chinese herbal medicine or acupuncture group (P<0.05). The total efficacy rate was 91.1%in the combination group, 71.1%in the Chinese herbal medicine group and 66.7%in the acupuncture group. There was a statistically significant difference in the total efficacy rate between the combination group and the Chinese herbal medicine or acupuncture group (P<0.05). Conclusions Acupuncture plus Chinese herbal medicine has a better therapeutic effect on allergic rhinitis. It can effectively relieve the clinical symptoms and signs and reduce IgE, IL-4 and IL-5 levels in the patients.

Objective:To compare and analyze the volatile components in different medicinal parts of silktree Albizzia julibrissin and their relative contents .Methods:Chromatography-mass spectrometry using headspace solid phase microextraction combined with gas method ( HS-SPME-GC-MS) was used to analyze the volatile components in the bark and flowers of silktree Albizzia julibrissin and the relative contents were calculated by a peak area normalization method .Results:In the bark and flowers of silktree Albizzia julibris-sin, totally 30 and 33 compounds were respectively identified , which respectively accounted for 73.20%and 88.29%of the total vola-tile.A total of 15 components, including alkanes, alkenes, aldehydes, furans, alcohols and acids were in the bark and flowers of silk-tree Albizzia julibrissin, among them, the content of cineole was the highest (bark:15.02%and flowers:21.9%).Conclusion:The HS-SPME technique can be used to analyze and compare the volatile components in the bark and flowers of silktree Albizzia julibrissin, which provides scientific basis for the reasonable development and application of the bark and flowers of silktree Albizzia julibrissin.

Objective To evaluate the effects of nutritional intervention on the incidence of malnutrition in patients on maintenance hemodialysis (MHD).Methods Totally 196 patients on MHD were randomly assigned to nutritional intervention group (n =98) and control group (n =98).Nutritional intervention or free diet were given in these two groups.The incidence of malnutrition in these two groups was recoded.Results The baseline age,biochemical indicators,and incidence of malnutrition were matched in these two groups (P ＞0.05).After 6 months,although the number of the patients with malnutrition [35.7％ (35/98)] was slightly increased in the intervention group,it showed no significant difference when compared with the baseline level [33.7％ (33/98),P ＞0.05].In the control group,however,the incidence of malnutrition [59.2％ (58/98)] significantly increased (P ＜0.05).The incidence of malnutrition was significantly lower in the intervention group than in the control group (P ＜ 0.05).Conclusion Nutritional intervention can lower the incidence of malnutrition in patients on MHD.

Researchers have long focused on the adaptive behavior,quality of life,dual diagnosis,personality motivation and families of persons with mental retardation,but failed to address virtue and well-being.Unlike even a decade ago,we can now well afford to turn the emphasis to the positive,internal states of those with mental retardation.Using the breakthroughs in positive psychology,these findings such as positive trait or positive experience,can proposes a new research agenda to mental retardation.Mental retardation can play an important role in positive psychology,but it needs the research and data support in future.

Objective:To develop an HPLC-MS/MS method for the determination of rosuvastatin in plasma and study the relative bioavailability and bioequivalence of the capsules and tablets in Chinese healthy volunteers. Methods: A single oral dose (20 mg of the test or reference preparation) was given to 24 male healthy volunteers in a randomized crossover study. The plasma concentration of rosuvastatin was determined by HPLC-MS/MS. The pharmacokinetic parameters were calculated and the bioavailability and bioequiva-lence of the two preparations were evaluated by DAS 3. 0 software. Results:After a single dose, the pharmacokinetic parameters of ro-suvastatin capsules and tablets were as follows:Tmax was (3. 56 ± 1. 68) h and (3. 63 ± 1. 56) h, Cmax was (21. 17 ± 13. 74) ng· ml-1 and (26.33 ±23.22) ng·ml-1, t1/2 was (10.68 ±5.50) h and (9.04 ±6.00) h, AUC0-t was (219.31 ±146.09) ng·h· ml-1 and (252. 43 ± 194. 96) ng·h·ml-1 , AUC0-∞ was (225. 32 ± 146. 76) ng·h·ml-1 and (257. 24 ± 194. 61) ng·h·ml-1 , respectively. The 90% confidential interval of AUC0-t, AUC0-∞ and Cmax was 81. 1%-106% , 81. 8%-105. 4% and 77. 9%-104. 5%, respectively. The mean relative bioavailability of the test preparation(the capsules) to the reference preparation(the tablets) was (100. 7 ± 54. 1)%. Conclusion:The test and reference preparations are bioequivalent.

A label-free electrochemical immunosensor using hollow structure nanomaterials based on its ordered porous and big surface area was designed. Au nanocage, with good conductivity, catalysis, and biocompatibility, was prepared and modified on the surface of glassy carbon electrode with graphene to immobilize antibody of microcystin directly. In the absence of microcystin, biosensor can obtain high current response signal of electrochemical probe ( [ Fe( CN) 6 ] 3-/4-. When microcystin was combined with its antibody specifically, the charge density and mass transfer resistance on the surface of electrode increased, resulting in a decrease of the corresponding peak current of [ Fe ( CN ) 6 ] 3-/4-. This change was in proportion to the concentration of microcystin indirectly. Experiment conditions such as cultivation time of antigen and concentration of antibody were optimized. The results showed wide linear range of 0. 05 μg/L-1. 0 mg/L and the detection limit of 0. 017 ng/mL. This sensor has good stability and simple production procedure. This sensor provides a new and simple means for the ultrasensitive determination of microcystins in real water samples.

Objective:To explore the behavioral preferences of pregnant women in Quzhou to obtain newborn health information, so as to provide a reference for relevant departments to formulate policies.Methods:From January 2020 to April 2021, convenience sampling was used to select 226 pregnant women who gave birth in Quzhou Hospital of Traditional Chinese Medicine as the research object. The self-designed Behavior Preference of Pregnant Women to Obtain Newborn Health Information Questionnaire was used to investigate pregnant women through the form of online return visits. A total of 226 questionnaires were issued, and 215 valid questionnaires were returned with the valid response rate of 95.13%.Results:Among 215 pregnant women, they thought it was difficult to obtain information on the prevention and treatment of common diseases (such as diaper rash, impetigo) , distinguishing and nursing of physiological phenomena (such as jaundice, galactorrhea) , form and content of early education, mental behavior building and premature infant health monitoring. These 215 pregnant women preferred to obtain newborn health information from the WeChat public platform/ application (APP) , brochures/billboards, online teaching and expert consultation.Conclusions:Pregnant women have diverse needs for newborn health information, and they prefer many ways to obtain it. In clinical practice, we should broaden the ways of obtaining specialized information to provide pregnant women with scientific and accurate newborn health information.
