Objective: The differences in the compounds between Lysimachia christinae and Desmodium styracifolium were compared in order to provide the references for pharmacodynamic differences of them. Methods: The RP-HPLC-UV and RP-HPLC-ELSD fingerprints of L. christinae and D. styracifolium were established, and the common peaks of two kinds of fingerprints were compared. Results: The HPLC-UV fingerprints of L. christinae were obviously different from the HPLC-ELSD fingerprints, and the strong peaks detected in UV were not the same as what detected in ELSD, so were those of D. styracifolium. There were 14 and 5 common peaks, respectively in the HPLC-UV and HPLC-ELSD fingerprints of L. christinae, while 28 and 18 common peaks, respectively in the HPLC-UV and HPLC-ELSD fingerprints of D. styracifolium. The similarities of chromatograms of D. styracifolium were better than those of L. christinae. Four common peaks were identified in the HPLC-UV fingerprints of L. christinae and D. styracifolium, and two common peaks in their HPLC-ELSD fingerprints. Conclusion: It is better using HPLC-ESLD to establish the fingerprints of L. christinae and D. styracifolium. The chemical constituents of L. christinae were significantly different between the different batches. However, little variation was found in the chromatograms between the different batches of D. styracifolium. The two plants may contain two same compounds with high content, which may have the function as the substantial bases of their treatments for the same indication. However, they may have their special efficacies.

Lysimachiae Herba and Desmodii Styracifolii Herba are common traditional Chinese medicines for treating lithiasis. Both of them have efficacies of clearing heat, diuresis and eliminating calculi. However, there are some differences in their clinic applications. The former is mainly used to treat hepatolithiasis, gallstones, jaundice, stranguria and gout; Whereas the latter is mainly used to treat urinary calculus. In this paper, the pharmacological effects of Lysimachiae Herba and Desmodii Styracifolii Herba on removing calculus, choleresis, anti-inflammation and oxidation resistance were compared and analyzed based on document retrieval. In conclusion, both of them show the preventive and therapeutic effects on kidney stones and gallstones. Particularly, Desmodii Styracifolii Herba has a better effect in treating the kidney stones, while Lysimachiae Herba has a better effect in treating cholesterol gallstones.

?AIM: To compare postoperative anti -inflammation effect and safety between bromfenac sodium eye drops and pranoprofen eye drops in patients after laser epithelial keratomileusis ( LASEK) .? METHODS: In the prospective, randomized and controlled study, 100 patients ( 200 eyes ) undergoing LASEK were randomized into the bromfenac sodium group (100 eyes) and control group (100 eyes).Patients in bromfenac sodium group received bromfenac sodium hydrate ophthalmic solution eye drops twice a day in 3d before surgery and 2wk after surgery, while the patients from the control group were given proanoprofen eye drops 4 times a day in the same period.At 1, 3, 5d, 1 and 3mo after surgery, irritative symptoms grade, duration of irritation, time for corneal epithelial healing, cornel haze, uncorrected visual acuity and intraocular pressure ( IOP ) were observed and compared between the two groups. Quantitative data were analyzed using independent samples t-test and ranked data were statistically analyzed using the Mann-Whiteney rank sun test.?RESULTS:There was no significant difference between two groups in irritative symptoms grade ( P =0.317 ), neither was existed between two groups in uncorrected visual acuity after surgery (P>0.05).There was no statistical significance in the time for corneal epithelial healing between two groups (P=0.551).?CONCLUSION: Bromfenac sodium eye drops ( 1g/L ) can achieve the same therapeutic effect as pranoprofen eye drops after LASEK.

The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.

Objective: To study the effects of betaxolol hydrochloride (BH) cationic liposomes on intraocular pressure (IOP), blood pressure ( BP) and heart rate ( HR) in rabbits to lay foundation for the development of new BH eye preparations. Methods:N-trimethyl chitosan (TMC60) was used as the coating material, the BH-loaded cationic liposomes (TMC60-BHL) were prepared. Total-ly 24 healthy rabbits were randomly divided into 4 groups using number method. Unilateral carotid artery intubation was carried out in the rabbits and connected a physiological recorder. TMC60-BHL, uncoated BHL, the marketed BH eye drops ( the positive control) and sterilized distilled water ( the negative control) with the volume of 50 μl was respectively used in one eye of the rabbits. IOP was detected by an ophthalmotonometer, and BP and HR were determined by the physiological recorder at the predetermined time intervals. Results:In the ipsilateral eyes, the maximum decrease in IOP for uncoated BHL and TMC60-BHL was 23. 00% and 26. 65%, respec-tively. In the contralateral eyes, the maximum decrease in IOP for uncoated BHL and TMC60-BHL was 18. 54% and 24. 33%, respec-tively. Compared with that of the positive control (19. 01%,15. 19%), the IOP decrease effect of uncoated BHL and TMC60-BHL was significant higher(P<0. 05), and that of TMC60-BHL was the highest(P<0. 05). BP and HR were both reduced in the various BH groups, while there was no notable difference when compared with those in the negative group(P>0. 05). Conclusion:TMC60-BHL shows significant IOP decrease effect without notable effect on BP and HR, which is valuable to be studied further.

Objective To investigate the role of plasma ? endorphin(? EP) in the regulation of cellular immunity, mainly IL 2R expression and IL 2 production in rat splenic cells, following traumatic hemorrhagic shock(T HS). Methods ①Wistar rats with T HS were used and sacrificed at 0, 1, 3, 6, 12 and 24 h after T HS. Plasma specimens were collected and ? EP levels in plasma were detected. Rats with sham operation were served as the controls. ②Models of in vitro experiment were used. Spenic cells were isolated and mixed from four normal rats and cocultured with shock plasma or shock plasma+? EP antiserum. ConA induced splenic cell IL 2 production and IL 2R expression were observed. Results ①Level of plasma ? EP increased remarkably after T HS immediately, peaked at 1 h, showed decreasing tendency and restored to pre shock level 24 h after T HS. ②Shock plasma significantly suppressed ConA induced splenic cell function; Levels of plasma ? EP were negatively correlated with IL 2 production and IL 2R expression in spenic cells; Compared with that in SP group, splenic cell function elevated markedly in SP+? EP antiserum group, but was still lower than that in controls. Conclusion The increased plasma ? EP following T HS is involved in the suppression of cellular immunity.
