1.Correlation between Ultrasonography and Pathology in Expansive Type of Hepatocellular Carcinoma
Chinese Journal of Ultrasonography 1995;4(6):247-250
Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.

Objective To provide the anatomical basis for treatment of comminuted fractures of the radial head with bending steel miniplates by observations of the proximal end of the radius (PEOTR) in adults and to investigate the effect of its application. Methods The PEOTR and the dynamic relationship between the articular circumference of the radial head and the ulnar radial notch were studied with 32 pairs of specimen of the dried radii and ulnae in adults. From Jan 1988 to Mar 1998, eleven cases of comminuted fractures of the radial head were treated with bending steel miniplates procedure; there were seven males and four females, with an average age of 35 years. According to Mason's grading, 9 cases were classified as Type Ⅲ radial head fractures, 2 cases as Type Ⅳ radial head fractures. Results The average length of the PEOTR was 41.6 mm. The radial neck deviated from the radial shaft at an angle of 164?. Then at the neutral position, the greatest range of pronation and supination of the forearm, the range of contact of radians and the range of non contact radian between the articular circumference of the radial head and the ulnar radial notch were 69?,108?,45? and 138?, respectively. The period of follow up in all cases was 20-38 months. All had bony union, with an average healing time of 8.5 months. Evaluation was done according to the criterion made by Broberg and Morrey. The result was excellent in 6 cases, good in 4 cases, and fair in 1 case. Conclusion The treatment of comminuted fractures of the radial head with bending steel miniplates is a safe and effective method.

AIM:To establish a HPLC method for determining contents of tetrahydropalmatine and pepper alkali in Zhitong Capsule(Rhizoma Corydalis,Fructus Piperis,Radix Paeoniae alba,etc.)to control its quality.METHODS:The samples were extracted in water by ultrasonic wave,and then extracted by aether to refine after being acidized by 1 mol/mL HCl.Following that the pH of water solution was adjusted to 9.0-10.0 by NH_3?H_2O,and then extracted by aether again.After that,the aether solution was collected to evaporation to dryness and metered by methanol.The sample solution was determined by high performance liquid chromatography on a Hypersil ODS 2 C_ 18 column(4.6 mm?250 mm,5 ?m)with mobile phase composed methanol-0.1% phosphoric acid water solution(the pH was adjusted to 6.0 by triethylamine)(55∶45).The flow rate was 1.0 mL/min,the column temperature was at 30 ℃ and the signal from 0 to 14.5 minutes were acquired at 280 nm,and that from 14.5 to 22 minutes were detected at 328 nm.RESULTS:The resolution of tetrahydropalmatine and pepper alkali was good,with no miscellaneous peak.The linear range was at 0.196-1.96 ?g(r=0.999 6)for tetrahydropalmatine,0.03-0.3 ?g(r=0.999 7)for pepper alkali.The average rate of recovery of tetrahydropalmatine was 97.74%(RSD= 0.42%,n=6),and that of pepper alkali was 104.51%(RSD=2.01%,n=6).CONCLUSION:The method is simple,reliable,accurate and can be applied to the quality control of the preparation.

In experimental group, gushukang was prescribed, 10 g/time and twice a day. In the control, jingfukang was prescribed, 6 g/time,twice per day. The course of treatment was 6 months.MAIN OUTCOME MEASURES: To observe the improvement of therapeutic effects, X-ray manifestation, bone density, serum calcium and phosphorus before and after treatment in two groups.RESULTS: The therapeutic effects were obtained in both groups. The effective rate was 93% in treatment group, better than the control (75%) ( P < 0.05). Concerning to remote ultrasonic conductive speed in radius(SOS), it was(3 934 ± 125) and(3 990 ± 105) m/s before and after treatment respectively in experimental group; and was(3 935 ± 110) and(3 940 ± 123) m/s in the control, indicating significant difference( P < 0. 05) . The difference in SOS before and after treatment in the control was not significant ( P > 0.05).There was no remarkable difference in serum calcium and phosphorus before and after treatment in two groups( P > 0.05).CONCLUSION: Gushukang, Chinese herbal patent for kidney tonification,provides better therapeutic effects on senile cervical spondylosis complicated with osteoporosis.

The safety of Chuangyuling (CYL) dressing-a multifunctional medicine carrying biomaterial was evaluated in order to provide foundation for the application of CYL as material used in the wound healing. The traditional Chinese medicine (TCM) extract solution was compounded with scaffolds (gelatin and Bletilla hyacinthine gum), and then frozen and dried to form spongy and porous material CYL. According to the standard of biological evaluation of medical devices that was instituted by the ministry of health of China, the biological evaluation of CYL dressing was conducted. The results showed that all the contents of biological evaluation test consisting of acute toxicity, skin irritation, sensitization and cytotoxicity met the requirement of standards. It was concluded that the biomaterial carrying TCM (CYL dressing) is safe for application of wound healing.

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease, characterized by progressive respiratory distress, intractable hypoxemia, respiratory failure and so on, with high mortality rate and lack of effective prevention and treatment strategies. In recent years, mesenchymal stem cell (MSC) can be used in the treatment of acute lung injury (ALI), which cannot only replace the damaged lung epithelial cells, but also promote tissue repair and alleviate ARDS by secreting anti-inflammatory and anti-fibrosis factors. This review focuses on the related mechanisms and signal pathways of MSC and its paracrine factors in the treatment of ARDS by regulating the balance of macrophage polarization.

Objective To determine the specific recognition of Echinococcus granulosus (E.g.) cyst fluid crude antigen (EgCF) and antigen B (EgB) by serum specific IgG and IgE using Western blotting during anaphylactic shock induced by E. g. in sheep, and to investigate the importance of defined characteristics and molecular weight of the specific antigens. Methods EgCF was obtained through local slaughterhouses in Urumqi from the cysts of infected sheep liver. Western blotting was used to analyze total specific IgG and IgE antibodies in serum from sheep infected with E.g. using either crude antigen of E. g. and EgB, and to understand specific recognition of hydatid cyst antigens by serum total IgG and specific IgE. Results SDS-PAGE and Western blotting showed that there were differences between EgB and EgCF in electrophoresis pattern. EgB was recognized by IgG from sera of infected sheep in a series of bands with molecular weight ranging from 31, 43 to 66.2 kDa. No binding of IgG against EgCF was observed in any serum from the infected sheep during anaphylactic shock. In contrast, specific IgE antibodies in E. g. infected sheep obviously recognized the single 43 kDa subunit of EgCF, but no binding of specific IgE against EgB was observed in sera of the infected sheep. Conclusion EgCF is consisted of antigenic components in which there is a specific antigen against IgE with a molecular weight of over 43 kDa. This component may lead to an anaphylactic shock induced by E. g. . EgB is a specific antigen against the total IgG but not to the specific IgE.
