Sulfur fumigation was a traditional maintenance method for traditional Chinese medicines (TCMs). However , as people have paid more and more attentions on the sulfur dioxide residue in the sulfur fumigated TCMs , China has gradually decreased and banned the sulfur fumigation for TCMs . This study adopted organic elemental analysis for the determination of sulfur contents in multiple TCMs . Elemental analysis can give accu-rate results with little sample amount in a short time . Data analysis indicated that the sulfur content of 0.5% can be set as a criterion for the identification of sulfur fumigated TCMs. Sulfur content of ten unknown TCMs were determined by elemental analysis and identified whether the TCMs have been fumigated by sulfur. The devel-oped elemental analysis method can be used as a screening method for rapid identification of TCMs' quality.

Objective To propose a method for the determination of droxidopa concentration in human plasma by HPLC method for the study of the pharmacokinetics of droxidopa.Methods After a single oral dose of 200 mg droxidopa capsule was administered to 12 healthy Chinese male volunteers,we used perchloric acid to precipitate proteinum and then determined the droxidopa concentration in plasma by HPLC.The pharmacokinetic parameters of droxidopa were calculated by 3P87 software.Results The linear range was 0.025-2 ?g/ml.Pharmacokinetic parameters were: T1/2(108.50?30.78)min,AUC(185.74?26.41) ?g?ml-1?min-1,CL(1.08?0.08)ml/min,Tmax(99.90?10.05)min,Cmax(0.74?0.08)?g/ml.At 10 h after administration,droxidopa was eliminated from the blood almost completely.Conclusion The method we proposed is sensitive,reproducible,and easy to operate.Pharmacokinetics of droxidopa in vivo is fitted to two-compartment model.

To explore the rules of medication for diabetes and diabetic complications based on analysis on 755 traditional Chinese medicine (TCM) prescriptions. The information in 755 papers published from 1995 to 2016 was got including 755 herbal prescriptions, 367 herbs, 33 330 effective cases. Based on the above information, usage frequency of single herb, efficiency and the rules of formulating prescription for different types of diabetes were analyzed and compared using Microsoft Excel 2010 and Clementine 12.0 software. In the treatment of diabetes and its complications, the top four diabetes symptoms are about diabetes, diabetic neurological complications, diabetic nephropathy and diabetic cardiovascular complications, and accounting for 31.62%, 29.82%, 8.87%, and 6.47% of the total number of effective cases. Further analysis of the top four illnesses found that single herb commonly used in the treatment of diabetes was Astragali Radix, Dioscoreae Rhizoma, Rehmanniae Radix, Trichosanthis Radix, Ophiopogonis Radix, etc. The commonly used drugs categories were tonic herbs, heat-clearing herbs and blood activating herbs; The single medicine commonly used in the treatment of diabetic neurological complications was Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma, Radix Salviae Miltiorrhizae et Rhizoma, Cinnamomi Ramulus, etc. The commonly used drugs categories were tonic herbs, blood activating herbs and heat-clearing herbs; The single herb commonly used in the treatment of diabetic nephropathy was Astragali Radix, Dioscoreae Rhizoma, Salviae Miltiorrhizae Radix, Poria, Fructus Corni, etc., the commonly used drugs categories were tonic herbs, blood activating herbs and damp-clearing herbs. The single herb commonly used in the treatment of diabetic cardiovascular complications was Astragali Radix, Salviae Miltiorrhizae Radix, Angelicae Sinensis Radix, Carthami Flos, Chuanxiong Rhizoma, etc., the commonly used drugs categories were blood activating herbs, tonic herbs and heat-clearing herbs. The rules of medication of TCM for diabetes, diabetic neurological complications, diabetic nephropathy and diabetic cardiovascular complications showed similar characteristics, tonic herbs were used the most frequently, supplemented by blood activating herbs, heat-clearing herbs and damp-clearing herbs. However, the principle of formula is a little different for different types of diabetes and diabetic complications, specifically. The prescriptions for diabetes and diabetic neurological complications consist of tonic herbs as the principal, supplemented by blood activating herbs and heat-clearing herbs; The prescriptions for diabetic nephropathy are composed of tonic herbs as the principal, supplemented by blood activating herbs and damp-clearing herbs, as well as tonic herbs and blood activating herbs were equal components in the prescriptions for diabetic cardiovascular complications, supplemented by heat-clearing herbs.

OBJECTIVETo study clinical efficacy of autologous bone graft for acetabular defect of Crowe III and IV hip dysplasia.

METHODSThe 22 patients with 25 hips of DDH (Crowe type III, IV) from March 2010 to May 2013 were retrospectively analyzed. Total hip arthroplasty (THA) combined autogenous bone grafting was performed for all these patients with osteoarthritis secondary to DDH. Among them, 19 patients were females (21 hips) and 3 patients were males (4 hips), ranging in age from 43 to 67 years old, averaged 55 years old. There were 6 hips with Crowe type III and 19 hips with Crowe type IV. Before surgery, all the patients had hip pain, limb shortening and hip limited function of hip joint. After 12 months, the degree of recovery about limb length, functional recovery, autogenous bone graft fusion were observed.

RESULTSAll the patients were followed up and no dislocation were occurred. At 12 months after operation, the average Harris hip joint llzncation score were 83.30±6.13, and 18 cases got an excellent result and 4 good. The length of lower limbs decreased from preoperative (3.20±0.81) cm to 12 months after operation (0.92±0.23) cm (t=14.864, P<0.05).

CONCLUSIONTHA combined with structural femoral head autograft for patients with osteoarthritis secondary to DDH can obtain favorable results, significantly improving the effect of operation treatment.

Objective To observe the clinical efficacy of acupuncture in treating severe pneumonia complicated with gastrointestinal dysfunction (GIDF).Method Sixty patients with severe pneumonia complicated with GIDF were randomized into a treatment group and a control group, 30 cases in each group. The two groups were both given conventional Western medications. In addition, the treatment group was intervened by acupuncture, and the control group by oral administration of Mosapride citrate capsules and enteral nutrition via nasogastric tube. After 7-day treatment, the changes of GIDF score, intraabdominal pressure, bowel sound and gastric retention were observed in the two groups, and the clinical efficacies were compared.Result The total effective rate was 93.1% in the treatment group versus 78.6% in the control group, and the between-group difference was statistically significant (P<0.05). The scores of GIDF and the indexes (intraabdominal pressure, bowel sound, and gastric retention) were significantly changed after the treatment in both groups (P<0.05). The scores of GIDF and the indexes in the treatment group were significantly different from those in the control group after the intervention (P<0.05).Conclusion Acupuncture can promote the recovery of gastrointestinal function in severe pneumonia patients, since it can significantly improve the intraabdominal pressure, bowel sound and gastric retention.
