OBJECTIVETo evaluate the clinical efficiency of selective cyclo-oxygenase-2 (COX-2) inhibitor compared to traditional nonselective NSAIDs for the prevention of heterotopic ossification (HO) after total hip arthroplasty (THA).
METHODSBy searching Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials) and Science Citation Index et al, only randomised controlled studies of selective COX-2 inhibitors VS nonselective COX-1 and COX-2 inhibitors for the prevention of HO after THA were included. The quality assessment of included studies was evaluated according to the standard of the Cochrane Collaboration, and the data were analysised by statistic software Stata 10.0. The HO incidence of both groups in different degrees was compared.
RESULTSFour eligible randomised controlled trials of totally 808 patients were included. Meta-analysis results showed that no statistically significant difference was found in overall incidence of HO (RR = 1.08, 95% CI: 0.71-1.64,P = 0.73), incidence of moderate severe HO (Brooker II and III) (RR = 0.83, 95% CI: 0.48-1.42, P = 0.49) and any grade of Brooker classification between two groups. In all included studies, 16 patients receiving nonselective COX inhibitor (4.4%) discontinued treatment because of gastrointestinal toxicity,whereas 10 patients in the selective COX-2 inhibitor group (2.7%) discontinued for gastrointestinal side effects.
CONCLUSIONThe selective COX-2 inhibitors are as equally effective as nonselective NSAIDs for the prevention of HO after THA. Considering the side effects of nonselective NSAIDs, selective COX-2 inhibitors were recommend for the prevention of HO after THA.

OBJECTIVETo observe anti-cancer effects of Jianpi Jiedu Recipe (JJR) on liver cancer (LC) rats with Pi deficiency syndrome (PDS) and its relation with the third complementary-determining region gene spectratyping of TCRVβ-chain (TCRVβCDR3).
METHODSRats were divided into 8 groups according to random digit table, i.e., the blank control group (normal), the PDS group, the LC model group, the LC-PDS group, high, middle, and low dose JJR groups (75.00, 37.50, 18.75 g/kg, respectively by gastrogavage, once per day), the thymus pentapeptide group (5 mg/kg, intramuscular injection, twice per week), 8 in each group. Rats in the normal group were administered with physiological saline by gastrogavage once per day. PDS rat model was prepared by bitter-cold purgation. LC model was prepared by orthotopic transplantation method. Twenty gene subfamilies of TCRβCDR3 in the thymus, liver, and LC tissues were detected by Gene Scan.
RESULTSHigh and middle dose JJR could postpone the growth of LC volume (P < 0.05), with equivalent liver index and thymus index to those of the normal group (P > 0.05). In thymus and liver tissue of the normal group, the number of clones (20 and 19), gene fragment number (220 and 113), Quasi-Gaussian distribution ratio of TCRVβCDR3 gene repertoire (100.0% and 42.1%), and fragment fluorescence peak area (6,539 ± 2,325 and 1,238 ± 439) were at the highest level among the 8 groups. TCRVβCDR3 expressions in thymus and liver tissue of high and middle dose JJR groups were approximate to those of the normal group. They were in the middle of the thymus pentapeptide group, the PDS group, the LC model group, and poorest in the LC-PDS group. TCRVβCDR3 in liver tissue expressed the best in the thymus pentapeptide group.
CONCLUSIONJJR might inhibit the growth of LC cells, and its mechanism might be related to enhancing TCRVβCDR3 spectratype expression.

Abstract: Objective By analyzing the frequency distribution of antihypertensive drug-related genotypes in hypertensionpatients treated in our hospital, so as to provide a clinical basis for individualized treatment of hypertension patients. Methods A total of 72 hypertensive patients treated in Hainan Hospital of PLA General Hospital from June 2021 to April 2022 were collected. PCR-melting curve method was used to detect CYP2D6*10 (c.100 C>T), CYP2C9*3 (c.1075 A>C), ADRB1 (c.1165 G>C), AGTR1 (c.1166 A>C), ACE (I/D), NPPA (T2238C) and CYP3A5*3 (A6986G), and the relationship between different genotypes and biochemical indexes was analyzed. Results According to the statistics of the gene and genotype frequency of each point in 72 patients, the gene frequencies of 7 sites all conformed to Hardy Weinberg equilibrium. There were gender differences in ADRB1 genotypes (χ2 = 5.878, P<0.05). There were statistical differences in triglycerides [AA: 1.4 (1.0, 2.0)mmol/L; AC: 2.2 (1.5, 2.5)mmol/L; P=0.038], total cholesterol [AA: 4.0 (3.1, 4.9) mmol/L; AC: 4.8 (4.0, 5.3) mmol/L; P=0.040] and low-density lipoprotein cholesterol [(AA: 2.4 (1.8, 3.3) mmol/L; AC: 3.2 (2.5, 3.5) mmol/L; P=0.035] among patients with different genotypes of AGTR1 locus. The patients with different genotypes of CYP2C9 locus had significant differences in their alanine transferase (ALT) [AA:16.9 (11.4,30.2) mmol/L; AC:10.4 (9.4, 18.2) mmol/L; P=0.040]. Aftergene-directed individualized therapy, different genotypes of CYP3A5 andAGTR1 affected the heart rate [CYP3A5: AA: (79.3±7.0) beats/min; AG: (69.8±6.8) beats/min; GG: (68.8±7.3) beats/min; P=0.010], systolic blood pressure [AGTR1: AA: (131.3±16.7) mmHg; AC: (140.6±11.8) mmHg; P=0.014] and diastolic blood pressure [CYP3A5: AA: (90.0±8.3) mmHg; AG: (78.7±10.8) mmHg; GG: (74.9±10.7) mmHg; P=0.025; AGTR1: AA: (75.3±10.2) mmHg; AC: (86.3±10.6) mmHg; P=0.001] of patients. Conclusions The related gene loci of antihypertensive drugs are an important basis for guiding the diversification and individualization of clinical medication. Clinicians need to consider the impact of related genes on drug efficacy and adverse reactions when prescribing.

OBJECTIVETo explore the correlation between Pi and Shen by observing the relationship between the metabolism of aristolochic acid (AA) and mRNA and protein expression levels of organic anion transporting polypeptide (oatp) superfamily member 2a1 and 2 b1 (oatp2al and oatp2bl) in renal, small intestinal, and large intestinal tissues of Pi deficiency syndrome (PDS) model rats.
METHODSTotally 46 Sprague-Dawley (SD) rats were randomly divided into four groups, i.e., the blank group (n = 12), the PDS group (n = 22), the AA-I group (n = 6), and the PDS AA-I group (n = 6). PDS model was established by subcutaneously injecting Reserpine at the daily dose of 5 mg/kg for 16 successive days. Carotid intubation was performed in 6 rats selected from the blank group and the PDS group. Pharmacokinetics of AA-I were detected at 5, 15, 30, 45, and 60 min after gastrogavage of AA-I. AA-I concentrations in renal, small intestinal, and large intestinal tissues of 10 rats selected from the PDS group were determined. Normal saline was administered to 6 rats selected from the PDS group and the blank group by gastrogavage. Renal, small intestinal, and large intestinal tissues were collected in the AA-I group and the PDS AA-I group at 60 min after gastrogavage of AA-I. mRNA and protein expression levels of oatp2a1 and oatp2b1 in each tissue were detected using real-time polymerase chain reaction (RT- PCR) and Western blot.
RESULTSCompared with the blank group, plasma concentrations of in vivo AA-I were obviously higher in the PDS group at 15, 30, 45, and 60 min after gastrogavage of AA-I with statistical difference (P < 0.05). Plasma concentrations of AA-I were obviously decreased at 60 min after gastrogavage of AA-I; AA-I concentrations in renal and large intestinal tissues were elevated; AA-I concentrations in small intestinal tissues were obviously reduced in the PDS group. There was no statistical difference in mRNA expression levels of oatp2a1 and oatp2b1 in the aforesaid three tissues of rats between the blank group and the PDS group. Compared with the blank group, mRNA expression levels of oatp2a1 and oatp2b1 decreased in small intestinal tissues of the AA-I group, and the mRNA expression level of oatp2a1 in large intestinal tissues significantly decreased (P < 0.05, P < 0.01). Compared with the PDS group, mRNA expression levels of oatp2a1 and oatp2b1 increased in renal tissues of the PDS AA-I group (P < 0.05); mRNA expression levels of oatp2b1 increased in large intestinal tissues of the PDS AA-I group (P < 0.05).
CONCLUSIONSThe difference in AA-I metabolism might be associated with changed expression levels of oatp2a1 and oatp2b1 in renal, small intestinal, and large intestinal tissues under Pi deficiency induced loss of transportation. Shen and Dachang played important roles in substance metabolism under Pi deficiency state, which proved Pi-Shen correlated in Chinese medical theories.

BACKGROUNDThe research of cancer in patients on hemodialysis (HD) in China has not been reported. The aim of this study was to investigate the clinical and histological features and outcomes of cancer in Chinese HD patients.
METHODSThe study subjects were 49 cancer patients (1.4%) out of 3448 end stage renal disease (ESRD) patients maintained on HD at China-Japan Friendship Hospital from October 1997 to July 2011.
RESULTSUrinary tract cancer (74%) was the most common followed by gastrointestinal tract cancer (12%), breast cancer (6%), lung cancer (4%), thyroid cancer (2%), and hematologic cancer (2%). Thirty-three patients (67%) had urinary tract transitional cell carcinoma (TCC) and 29 of them had aristolochic acid nephropathy (AAN) as underlying disease. Death occurred in eight patients out of 49, and the survival rate of HD patients with cancer was similar to those without cancer (P = 0.120).
CONCLUSIONThe urinary tract TCC is the most common cancer in HD patients with AAN in one of the centers of northern China.
