1.Studies on the Active Constituents and Their Contents of stem and Leaf of Qianhu by RP-HPLC
Chinese Traditional and Herbal Drugs 1994;0(01):-
Chemical constituents of the aerial parts of Qianhu were compared with those present in the roots by RP-HPLC. It was found that the constituents in aerial parts of Peucedanum praeruptorum are similar and higher in content than that in the roots. So it is possible that the aerial parts can be used instead of the roots of the plant. But the chemical constituents in the aerial parts and the roots of P. decursivum are quite different, rendering it impossible to use the aerial parts instead of the roots of the plant.
4.A report of 18-month follow-up study on a case of classic maple syrup urine disease
Journal of Clinical Pediatrics 2013;(10):968-971
Objectives To explore the long-term prognosis, treatment (especially dietary treatment) of classic maple syrup urine disease. Methods The complications and dietary treatment were observed by follow-up study of a classic MSUD patient. Results The patient have obvious damage in nervous system. However, reasonable dietary leucine tolerance therapy after the neonatal period can effectively reduce the metabolic crisis and complications. A mutation in BCKDHB gene was detected in the patient by genetic testing. Conclusion It is suggested that dietary restriction and monitoring of branched-chain amino acids are helpful to reduce the development of acute metabolic crisis and complications and improve the quality of life.

Swertio elongata S. W. Lioa dt T. N. He (Gentianaceae) has been found to be effective in the treatment of liver disease. The present investigation resulted in tho isolation and structure elucidation of four xanthone glycoside, two secoiridoid glycosides and a lignan glycoside in the plant. According to the chemical transformation, spectral (UY, IR, 1H and 18CNMR, MS) properties and comparison with reference samples, the structures of four xanthone glycosides were established as:4-?-D-glucopyranosyl-1, 3, 6, 7-tetrahydroxyxanthone (Ⅶ), 2-?-D-glucopyranosyl-1,3,6, 7-tetrahydroxyxanthone (Ⅵ), 8-O-?- D- glucopyranosyl-1,3, 5-trihydroxyxanthone (Ⅳ) and ?-O-?-D-glucopyranosyl-1, 5-dihydroxy-3-methoxyxanthone (Ⅴ). The structures or two secoiridoid glycosidcs were identified as swertiamarin (Ⅱ) and desacetylcentapicrin (Ⅰ). The structure of lignan glycoside was identified as (+) hydroxypinoresinol-1-?- D-glucosid. (Ⅲ).

BACKGROUND:Tissue patch is used to increase bone mass after mandibular molar extraction, which is conducive to late-stage repair, but it is unexpectedly found that after implantation of tissue patch, incidence of dry socket is significantly reduced.OBJECTIVE:To assess the efficacy of tissue patch for the control of dry socket caused by mandibular molar extractionvia the method of systematic review. METHODS:MEDLINE (OVID), CENTRAL, EMBASE and CBM were searched for clinical randomized controled trials and clinical controled trials. The keywords were “dry socket, tissue patch, acelular dermis matrix, tooth extraction” in English and Chinese. The references of the included studies and 19 Chinese dental journals were hand-searched. Two reviewers independently assessed the risk of bias using Cochrane Colaboration’s tool, and extracted data. Meta-analysis was delivered with Revman 5.1.RESULTS AND CONCLUSION:Eight studies, including five randomized controled trials and three clinical controled trials, were included. Totaly 2 052 participants were involved. Seven of the included studies had moderate risk of bias and one had high risk of bias. Meta analysis showed that implantation of the tissue patch into the extraction socket could reduce 86% of the risk of dry socket (relative risk=0.14, 95% confidence interval [0.08, 0.26], P < 0.000 01). Sensitivity analysis showed that this outcome was relatively stable. Implantation of tissue patch into extraction socket could significantly reduce the risk of dry socket, but more randomized controled trials are needed.

OBJECTIVE:To explore quality control of plasma concentration monitoring for sodium valproate and to improve the quality of pharmaceutical monitoring.METHODS:The statistical and continuous analysis of sodium valproate control data from our hospital of 2008 were conducted using fluorescence polarization immunoassay(FPIA).RESULTS:Mean recovery and RSD were 98.37% and 1.94% for low control samples,99.33% and 2.88% for medium control samples,98.17% and 4.10% for high control samples.The RSD of sample was lower than 5% and in line with the requirement for biological sample determination in Chinese Pharmacopoeia.CONCLUSION:FPIA is a comparatively accurate and stable method for plasma concentration monitoring of sodium valproate.

10.Disease modifiers and novel markers in hepatitis B virus-related hepatocellular carcinoma
Journal of Liver Cancer 2024;24(2):145-154
Chronic hepatitis B (CHB) infection is responsible for 40% of the global burden of hepatocellular carcinoma (HCC) with a high case fatality rate. The risk of HCC differs among CHB subjects owing to differences in host and viral factors. Modifiable risk factors include viral load, use of antiviral therapy, co-infection with other hepatotropic viruses, concomitant metabolic dysfunctionassociated steatotic liver disease or diabetes mellitus, environmental exposure, and medication use. Detecting HCC at early stage improves survival, and current practice recommends HCC surveillance among individuals with cirrhosis, family history of HCC, or above an age cut-off. Ultrasonography with or without serum alpha feto-protein (AFP) every 6 months is widely accepted strategy for HCC surveillance. Novel tumor-specific markers, when combined with AFP, improve diagnostic accuracy than AFP alone to detect HCC at an early stage. To predict the risk of HCC, a number of clinical risk scores have been developed but none of them are clinically implemented nor endorsed by clinical practice guidelines. Biomarkers that reflect viral transcriptional activity and degree of liver fibrosis can potentially stratify the risk of HCC, especially among subjects who are already on antiviral therapy. Ongoing exploration of these novel biomarkers is required to confirm their performance characteristics, replicability and practicability.
