Clinical and imaging efficacy observation of closed reduction and plaster splint fixation in the treatment of ge-rontal patients with distal radius fractures / 中国基层医药

Objective To discuss the clinical efficacy of closed reduction and plaster splint fixation ( CRPSF) in the treatment of gerontal patients with distal radius fractures ( DRF) .Methods 76 elderly patients with DRF who treated by CRPSF were selected .According to AO classification of fractures ,the patients were divided into three groups,the A group had 27 cases;B group had 26 cases,C group had 23 cases.The treatment effect was evalua-ted by analyzing the follow-up data,the corresponding imaging measurement parameters and clinical scores .Results All patients had 12-month clinical and imaging follow-up.In the last follow-up, the arm-shoulder-hand dysfunction score and palmar angle ,ulnar deviation angle of A and B group were significantly better than those of C group , the differences were statistically significant(all P0.05).In the last follow-up,the satisfaction score of C group was slightly lower than that of the A or B group,but had no statistically significant difference (P>0.05).Conclusion CRPSF in the treatment of gerontal pa-tients with DRF has good function and imaging effects ,and the improvement level has a certain relationship with the degree of fracture,but has no significant impact on the patients'satisfaction.

Impact on membrane separation process of volatile oil-bearing water body of notopterygii rhizoma et radix by inorganic salting pretreatment / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the best pretreatment condition of inorganic salting on volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation.</p><p><b>METHOD</b>The simulative system of volatile oil-bearing water body of Notopterygii Rhizoma et Radix was pre-treated before membrane separation by salting. The best conditions of salting were determined by selecting types and amounts of inorganic salt as investigate factors and comparing membrane flux and oil retention rate.</p><p><b>RESULT</b>The best pretreatment condition of inorganic salting on volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation was to add 2% sodium chloride (NaCl) according to the amount of oil-bearing water body. Gas chromatographic fingerprint showed that inorganic salting did not affect the active ingredient of volatile oil.</p><p><b>CONCLUSION</b>Adding NaCl to volatile oil-bearing water body of Notopterygii Rhizoma et Radix before membrane separation can optimize membrane processes by improving membrane flux.</p>

Comparison of essential oil enriched with ultrafiltration method and extraction method respectively from essential oil-in-water emulsion of Citri Reticulatae Pericarpium Viride by GC-MS / 中国中药杂志

<p><b>OBJECTIVE</b>To study on the separation from essential oil-in-water emulsion of Citri Reticulatae Pericarpium Viride by ultrafiltration and acetoacetate extraction methods respectively, and the comparison of the oil yields and chemical compositions.</p><p><b>METHOD</b>Essential oil-in-water emulsion of Citri Reticulatae Pericarpium Viride was separated by ultrafiltration and acetoacetate extraction methods respectively, and the chemical compositions were analyzed and compared by GC-MS.</p><p><b>RESULT</b>Ultrafiltration method could enrich essential oil more and its chemical compositions were more similar to the essential oil prepared by steam distillation method.</p><p><b>CONCLUSION</b>Ultrafiltration method is a good medium to separate essential oil from essential oil-in-water emulsion of Citri Reticulatae Pericarpium Viride.</p>

Study on correlation between physical and chemical parameters of oil-bearing water bodies and ultrafiltration membrane flux in four simulative system of traditional Chinese medicine volatile oil / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the correlation between physical and chemical parameters of oil-bearing water bodies and ultrafiltration flux in the four simulative system of traditional Chinese medicine ( TCM) volatile oil.</p><p><b>METHOD</b>Four simulative systems of TCM oil-bearing water bodies such as Tsao-ko Amomum Fruit were selected as the experimental subjects. The membrane separating under the best conditions was carried out, membrane flux, physical and chemical parameters of stock solution and permeate were collected, and SPSS computer software was used for data processing.</p><p><b>RESULT</b>The membrane separation significantly changed the physical and chemical properties of oil-bearing water bodies, resulted in lower electrical conductivity and turbidity and pH value increased; Physical and chemical parameters also affected the membrane process significantly, and the flux varied with the electrical conductivity, pH, turbidity and viscosity.</p><p><b>CONCLUSION</b>There is significant correlation between physical and chemical parameters of oil-bearing water bodies and their ultrafiltration flux in the four simulative systems of TCM volatile oil.</p>

Optimization of Reverse Osmosis Process of Oil-Bearing Water Bodies Ultrafiltrate from Compound Chuanxiong Capsules / 中国中医药信息杂志

Objective To investigate the effect of liquid temperature, pressure, concentration, pH parameters on the membrane process and rejection in the process of using reverse osmosis membrane to concentrate oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules, and optimize the process. Methods With oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules volatile oil as the research object, the changes in flux under different operating parameters was measured. Results For this system, suitable operation parameters was as follows: pressure was 1.6 MPa, temperature was 35～ 40 ℃, pH was 9～10. Conclusion Using reverse osmosis membrane to concentrate oil-bearing water bodies ultrafiltrate of Compound Chuanxiong Capsules volatile oil, better flux and rejection can be obtained at the appropriate operating conditions.
