Objective Nasal administration,as a common means of treatment of respiratory diseases,may normally cause bronchospasm,cough and other adverse reactions,the efficiency of nasal nebulizers has been criticized as well.This paper aims to develop a medicine atomizing device,pharmaceutically atomized in solving the existing problems,providing a modern instrument for treatment of respiratory diseases by traditional Chinese medicine.Methods The device could prepare medicine by decoction and filtration,which means this unit is divided into two functional modules,medicine preparation and herbal atomization.1 200 W heating plate is placed in decoction unit and is programmed to fit traditional decoction protocol.Steam and ultrasonic nebulised medicine are combined in atomizing unit.Another non-contact infrared heating unit also located in to control the temperature precisely.Different forms of traditional Chinese medicine and different filtration methods were selected to optimize the atomizing effect.Results An implementation of two sequence of filtration enabled optimization of atomizing.After 15 volunteers'trial,this device functioned well on Bama nasal medical protocol,and could effectively avoid the adverse reactions of the traditional way of cold fog atomizing.Conclusions The nasal nebulizer equipment on which Chinese herbal medicine treatments could directly performed,produced atomized mist particle size suitable for nasal treatment,and by generating warm steam to avoid the common clinical administration caused choking to hypoxia and other adverse reactions.Meanwhile,instrument has a friendly interactive feature to meet the clinical requirements for medicine nebulizer treatment.

Objective To analyze the clinical characteristics of hospital acquired mycotic pneumonia in elderly patients (aged≥ 80 years).Methods The clinical data were reviewed on 64 cases of elderly patients aged 80-93 years with hospital-acquired infection of mycotic pneumonia from June 2007 to July 2011.According to the results of sputum culture,therapy plan was made and antibiotic drugs were selected.Results Among these 64 patients,Candida mycoderma (62.5 ％,40 cases) occupied the first place and C.glabrata (20.3％,13 cases) was the second place (x2 =127.50,P＜0.01).Their chest x-ray or CT films were not characteristic,but lamellar shadows (68.8％,44cases) and cotton-like shadows (40.6 ％,26 cases) were found in the majority.60 cases (93.8 ％ ) of these patients had more than 3 complications,and 58 cases (90.6％) of them took over 2 kinds of antibiotics.The improvement rate of these patients was 81.3％ (52 cases)and mortality rate was 18.8％(12 cases).Conclusions Elderly patients (aged≥ 80 years) with hospital acquired infection of mycotic pneumonia have high incidence and mortality rate.The key point to cure is to make an early diagnosis and treat them as early as possible.

This review introduces the mechanism and advantages of laser acupuncture and moxibustion, the biological effect of low-level laser, the characteristics of acupuncture point area and the experimental laws of biological effect.On this basis, the existing problems in clinical application of laser acupuncture and laser acupuncture apparatus are pointed out.The combination therapy method with various wavelength are also discussed, and future development directions in the study are prospected.

Myofascial pain syndrome (MPS) is a common skeletal muscle pain and dysfunction,characterized by the presence of myofascial pain points (MTrPs).At present,the main method of locating MTrPs is palpation which has lower intra-rater reliability,and lacks an objective evaluation approach for therapeutic effects.Therefore,the research on objective evaluation of the characteristics of MPS has been receiving great attention.These studies involve stiffness of trigger points,fascia thickness,surface temperature and other aspects through various methods,such as ultrasonic imaging,magnetic resonance imaging,infrared thermal imaging.In this paper,the research progress and methods of MPS in imaging were surveyed,which can provide the basis for the clinical diagnosis and objective evaluation of therapeutic effects.

ObjectiveTo observe the clinical effect of acupoint application on lipid metabolism in elderly diabetics with hyperlipidemia.Methods60 elder diabetics were divided into two groups.In the drugs group,patients were purely treated with simvastatin or lipanthyl.In the acupoint group, patients received acupoint application.The serum total cholesterol(TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipeprotein (HDL-C), aPoprotein A(ApoA) and apoprotein B(ApoB) ere measured respectively.Adverse events were observed.ResultsThe levels of TC、TG、LDL-C、ApoB were significantly dechned(all P ＜0.01 ～0.05).However,the rates of reduce lipid had no significant difference in two groups(P ＞0.05).The levels of HDL-C and ApoA were increased in the drugs group,but the homologous levels in the acupoint group showed no significantly change(all p ＞ 0.05).The adverse reaction in the acupoint group was significantly lower than that in the drugs group(P ＜0.05).ConclusionAcupoint application could decrease the blood lipid spectrum in the senile diabetics with hyperlipidemia.This therapeutics could reduce adverse drug reactions.

Objective To design a laser acupuncture instrument with dual wavelength and multi-channel,under the guidance of traditional Chinese medicine acupuncture theory and according to low-level laser induced effect in bio-tissues and compatibility characteristics of acupuncture points.Methods Using SCM and semiconductor laser,hardware circuitry was designed to achieve the basic functions of the instrument,and the corresponding PC software was developed.Results The laser acupuncture treatment for several acupuncture points could be carried out at the same time with the same or different laser parameters (wavelength,power density,continuous/pulse),and each channel could output 635 nm and 808 nm laser,with continuous adjustable power.Conclusions The dual wavelength multi-channel laser acupuncture instrument can meet the needs of compatibility during clinical acupuncture treatment and is easy to operate.

There is a considerable increase in incidence of proximal humerus fractures.Locking plates are widely applied in the treatment of proximal humerus fractures due to their superior advantages.However,they may still lead to a high incidence of complications,especially in complex proximal humerus fractures.Reconstruction of medial support for a proximal humerus fracture can reduce complications effectively.At present,there is no consensus on the optimal method for medial support.The methods commonly used for medial support as an auxiliary fixation of proximal humerus fracture include screw support,bone transplantation,bone substitute and dual plates,all of which are discussed in this review.
