China Pharmacy 2005;0(15):-
OBJECTIVE: To study the effects of Semen Litchi on the expressions of S180 and EAC tumor cells and Bax and Bcl-2 proteins in rats. METHODS: EAC, S180 and hepatic carcinoma tumor-bearing mice models were established in mice by inoculating them with tumor strains. EAC, S180 and hepatic carcinoma suspensions were diluted respectively with normal saline in a ratio of 1∶1 for the preparation of tumor-bearing ascites suspension. Each rat was subcutaneously inoculated with the mixture 0.2 mL via axilla 24 hours before medication, with the whole sterile operation finished within 60 minutes. After treated with Semen Litchi for 10 consecutive days, the growth of EAC, S180 and hepatic carcinoma in mice was observed. RESULTS: The growth of EAC and S180 and hepatic carcinoma cells in mice was significantly inhibited by Semen Litchi. CONCLUSION: Semen Litchi can inhibit the growth of S180 and EAC tumor cells in vitro and in vivo, and its antitumor effect is related to its ability to promote apoptotic of tumor cells.

China Pharmacy 2001;0(11):-
OBJECTIVE: To study the effects of extracts of the seed of Litchi (ESL) on the expression of estradiol receptor (ER) and progestogen receptor (PR) in mammary tissue and apoptosis of mammary glandular cells in rats with hyperplasia of mammary glands (HMG). METHODS: The HMG model was induced by intramuscularly injecting with 0.5 mg?kg-1 estradiol benzoate for 25 days, subsequently intramuscularly injecting with 4 mg?kg-1 progesterone for 5 days. 60 healthy nonfertile SD rats were divided into normal group, model group, rujieping group and high-dose, medium-dose and low-dose ESL groups, treating with distilled water, distilled water, 3.3 g?kg-1 Rujieping and 44, 22, 11 g?kg-1 ESL via i.g. gtt once a day for 30 days, respectively. Immunohistochemical method was applied to observe the expression of ER and PR in rat mammary tissue and apoptosis of mammary glandular cells. Uterus index was also calculated. RESULTS: High-dose and medium-dose of ESL can inhibit the expression of ER and PR of mammary gland in HMG rats and induce apoptosis of mammary glandular cells(P

China Pharmacy 2005;0(24):-
OBJECTIVE: To explore the antioxdant action of Xiangsha liujun pill in hyperlipidemia model rats. METHODS: Hyperlipidemia model was established by intragastric administrating emulsion in rats. The levels of blood lipids, serum SOD activity and MDA content in rats before and after intragastric administration of Xiangsha liujun pill were measured. RESULTS: Xiangsha liujun pill markedly inhibited the concentrations of serum total cholesterol (TC), trglyceride (TG), low-density lipoprotein (LDL) and high-density lipoprotein (HDL), promoted the activity of SOD and decreased the content of MDA (P
5.Determination of Ritodrine in Human Plasma by LC-MS
China Pharmacy 2005;0(20):-
OBJECTIVE:To establish an LC-MS method for the determination of the ritodrine content in human plasma.METHODS:The determination was performed on Agilent Eclipse Plus C18 column with the column temperature kept at 40 ℃.The mobile phase consisted of methanol-water(95∶5,containing 0.02 mol?L-1 ammonium formate)with a flow rate of 0.5 mL?min-1.The extraction agent was acetic ether-dichloromethane(4∶1).A triple quad mass spectrometer system equipped with an electro spray ionization ion-trap source was used as the detector and operated in the positive ion model.Selected reaction monitoring(SRM)was employed to detect ritodrine(m/z 288.2→121.1)and the internal standard dobutamine(m/z 302.1→107.0).RESULTS:The linear range of ritodrine was 0.25~100 ng?mL-1(r=0.999 1),with the lower limit of quantification at 0.25 ng?mL-1.Both the intra-day RSD and inter-day RSD were less than 15%.The methodological recovery was 98.00%~103.44%.CONCLUSION:The method is sensitive,accurate,reproducible,specific and suitable for the pharmaceutical study of ritodrine.

OBJECTIVE:
To investigate the clinical features of fungal rhino-sinusitis.
METHOD:
Clinical data of 189 patients suffering from fungal rhino-sinusitis treated by functional endoscopic sinus surgery was analyzed retrospectively. The analyzed data included clinical type, age of onset, predilectionsite, reason, and surgical outcome.
RESULT:
Among the 189 patients with fungal rhino-sinusitis,181 cases were fungal ball,6 cases were allergic fungal rhino-sinusitis, 1 case was acute invasive fungnal rhino-sinusitis, 1 case was chronic invasive fungnal rhino-sinusitis. One hundred and twenty-eight cases were in the maxillary sinus (123 cases were unilateral, 5 cases were bilateral). Nineteen cases were in the ethmoid sinus. 31 cases were in the sphenoid sinus. Two cases were both in the maxillary sinus and ethmoid sinus, 1 case was both in the maxillary sinus and sphenoid sinus. Two cases invasive fungnal rhino-sinusitis had diabetes history. All the patients treated by functional endoscopic sinus surgery, 184 cases without recurrence, 5 cases suffered re-operation.
CONCLUSION
The incidence of fungal rhinosinusitis is showing a rising trend, fungal ball is the highest. The sinusitis patients whom we highly doubt for fungal infection should be confirmed by using sinonasal secretion smear, cultivation and histopathological examination. Surgical treatment should completely remove the fungal masses, to avoid reoperation.

Calcaneal fractures, common injury to foot, usually require surgery if complicated with an obvious displacement. Since open reduction and internal plate fixation often leads to wound infection, more and more minimally invasive surgery has been adopted for calcaneal fractures. As a minimal invasive treatment, intramedullary fixation can be used to treat calcaneal fractures of Sanders types Ⅰ-Ⅳ. Calcanail and C-Nail are 2 major types of intramedullary nails that have been used to treat calcaneal fractures in Europe and the United States since 2011. This article reviews the basic structural features, biomechanical properties, surgical procedures and clinical efficacy of these intramedullary nails.

Objective To testify the limitation of Sanxiao differentiation and to prove the objectivity and practicability of three-typed syndrome differentiation by mining data of common diabetic symptoms and symptomatic flocks from the gathered cases of type 2 diabetes mellitus. Methods The diagnotherapeutic data of 533 cases of type 2 diabetes were collected applying structurally clinical informational gathering system. Then the symptoms, symptomatic flocks and correlated symptoms of typical Sanxiao symptoms were analyzed. Result Among those symptoms, weakness was the tiptop of 473 cases, accounting for 88.74%. 303 cases with thirst and pleased drink, among which 32.23% had both polyuria together with polyphagia and hungary. 106 cases had polyuria (19.89%), 26.46% of which were thirst and pleased drink accompanied with polyphagia and hungary. 77 cases were polyphagia and hungary (14.45%), among which 35.37% had both polyuria together with thirst and pleased drink. 2.25% cases had Sanxiao symptoms at the same time. The frequency of deep and thready pulse was the most aommonly one, which accounted for 133 cases (24.95%). Tongue quality mainly appeared dull and red (218 cases, 40.9%). Among the symptomatic flocks, tongue quality weak and white often accompanied by thirst, please drink and weakness. Conclusions The theory of treatment based on syndrome differentiation of Sanxiao exists localization in the regarding the complexity of type 2 diabetes symptoms and symptomatic flocks. The three-typed syndrome differentiation possesses the objectivity and practicability.
