ABSTRACT

Objective: To investigate the factors affecting the success of conversion therapy in patients with initially unresectable colorectal cancer liver metastases (CRLM) in order to provide evidence-based medical evidence for formulating individualized treatment strategies for patients. Methods: A retrospective case-control study was used in this study. Clinical data of 232 patients with initially unresectable CRLM receiving first-line systemic treatment in Sun Yat-sen University Cancer Center from January 2013 to January 2020 were collected, including 98 patients of successful conversion and 134 patients of failed conversion as control. Conversion therapy scheme: 38 patients received FOLFOXIRI regimen chemotherapy (irinotecan, oxaliplatin, calcium folinate and fluorouracil), 152 patients received FOLFOX regimen (oxaliplatin, calcium folinate and fluorouracil), 19 patients received FOLRIRI regimen (irinotecan, calcium folinate and fluorouracil), 23 patients received systemic chemotherapy combined with fluorouridine hepatic artery infusion chemotherapy; 168 patients received targeted therapy, including 68 of bevacizumab and 100 of cetuximab. Logistics analysis was used to compare the factors affecting the success of conversion therapy. The Kaplan-Meier method was used to calculate progression-free survival (PFS), and the Log-rank test was used for survival comparison. Results: Among 232 patients, 98 patients had successful conversions and 134 patients had failed conversions with a successful conversion rate of 42.2%, meanwhile 30 patients underwent simple hepatectomy and 68 underwent hepatectomy combined with intraoperative radiofrequency ablation. After first-line chemotherapy, 111 patients (47.8%) were partial remission, 57 patients (24.6%) were stable disease, and 64 patients (27.6%) were progression disease. During the median follow-up of 18.8 (1.0-87.9) months, 148 patients were dead or with tumor progression. The median PFS time of patients with successful conversion was longer than that of patients with failed conversion (31.0 months vs. 9.9 months, P<0.001). Univariate analysis found that the bilobar distribution of liver tumors (P=0.003), elevated baseline carcinoembryonic antigen (CEA) levels (P=0.024), tumor invasion of the portal vein (P=0.001), number of metastatic tumor>8 (P<0.001), non-FOLFOXIRI (P=0.005), and no targeted therapy (P=0.038) were high risk factors for the failed conversion therapy. The results of multivariate logistics analysis indicated that the number of metastatic tumor >8 (OR=2.422, 95%CI: 1.291-4.544, P=0.006), portal vein invasion (OR=2.727, 95%CI: 1.237-4.170, P=0.008) were the independent risk factors for failed conversion therapy, while FOLFOXIRI regimen (OR=0.300, 95%CI: 0.135-0.666, P=0.003) and targeted drugs (OR=0.411, 95%CI: 0.209-0.809, P=0.010) were independent protective factors for successful conversion therapy. Conclusions: The number of metastatic tumor and portal vein invasion are key factors that affect the outcomes of conversion therapy for initially unresectable CRLM. If a patient can tolerate chemotherapy, a combination program of three-drug and targeted therapy is preferred for the active conversion therapy.

ABSTRACT

Objective: Explore the usage of anti-hypertension drugs and the rationality of hypertension prescription among the primary health centers in Dongcheng District, Beijing. Method: This cross-sectional and retrospective study was applied to analyze the hypertension prescriptions from the 8 community health centers in Dongcheng District. The anatomical, therapeutic and chemical classification (ATC) codes were used to determine the drug category. ATC information was used to filter data containing antihypertensive drugs, and group the number and proportion of ATC categories. The type of drug was judged by its generic name. According to the diagnosis information in the prescription, the prescription containing the Western medicine diagnosis of hypertension was screened out. The comorbidities of hypertension in the study included 7 types of diseases including diabetes, chronic kidney disease, coronary heart disease, heart failure, atrial fibrillation, stroke, and dyslipidemia. The analysis of prescription rationality included rationality of combination medication, rationality of drug dosage and rationality of drug price. The agreed daily dose (DDD) method was used to analyze the rationality of drug dosage. The drug utilization index (DUI) was used as a quantitative indicator to estimate the rationality of medication, and overdose was expressed by DUI>1. The reasonableness of the drug price was judged based on the price of the drug and whether it was a drug in the "4+7" plan. Results: A total of 658 140 prescriptions were extracted as the final data set, involving 7 categories and 60 commonly used anti-hypertensive drugs, and the corresponding cost of medication was ¥96.58 million. Drugs were prescribed according to comorbidities, and the choice followed the international guidelines. Calcium channel blockers (CCB) were the most prescribed drugs in the prescriptions of patients with comorbidities, and α-adrenergic receptor antagonists were the least prescribed drugs. The proportion of diuretics prescribed in hypertensive patients complicating with heart failure was 21.17% (505/2 385), which was much higher than that of patients complicating with other comorbidities (P<0.05). The proportion of diuretics prescribed in hypertension patients complicating with dyslipidemia was lower than that of patients with other comorbidities (2 639 (0.94%), P<0.05), and β-blockers (BB) or angiotensin Ⅱreceptor blockers (ARB) were more likely to be selected (BB: 59 348 (21.08%), ARB: 51 356 (18.24%))in these patients. The proportion of BB in prescriptions for hypertension patients with chronic kidney disease was lower than that of patients with other comorbidities (P<0.05). The proportion of BB in prescriptions for hypertension patients with coronary heart disease was higher than that of other comorbidities (P<0.05). Hypertension patients with atrial fibrillation or stroke accounted for a higher proportion of CCB prescriptions (P<0.05). Single antihypertensive drug prescriptions accounted for the highest proportion, 61.19% (402 745/658 140). Two-combination prescriptions accounted for the highest proportion of combination prescriptions, 72.19% (184 392/255 395). CCB based two-combination prescriptions accounted for the highest proportion, 122 350(66.36%). ARB-based tri-combination prescriptions accounted for the highest proportion, 48 915(89.50%),followed by CCB based tri-combination prescriptions (44 732(81.85%)).There were 2 174 (0.33%) prescriptions with unreasonable combination therapies and DUI>1 were found in 48 out of 60 commonly used drugs. In all possible antihypertensive drugs, only 40.92% (109 227/266 993)followed the "4+7" plan. Conclusions: The anti-hypertensive agents from these prescriptions in the primary health centers are diverse, and the choice is generally complied with the guidelines, but some unreasonable situations existed, especially on the combined anti-hypertensive medication, overdose, and"4+7"plan is not followed completely.

ABSTRACT

OBJECTIVE@#To investigate the risk factors of vertebral refracture after percutaneous kyphoplasty (PKP) for osteoprotic vertebral compression fractures (OVCFs), and to provide reference for clinical prevention.@*METHODS@#A retrospective analysis of 228 OVCFs patients who met the inclusion criteria admitted from November 6, 2013 to December 14, 2018. There were 35 males and 193 females, with a male-to-female ratio of 3∶20, and aged 58 to 91 years with an average of (69.70±7.03) years. All patients were treated with PKP and had complete clinical data. According to whether refracture occurred after operation, they were divided into refracture group (24 cases) and non refracture group (204 cases). Factors that may be related to refracture (including gender, age, surgical segment, number of vertebral bodies in the surgical segment, whether combined with degenerative scoliosis, whether anti-osteoporosis treatment) were included in the univariate analyses, and the single factor analysis of statistically significant risk factors was carried out with multiple Logistic regression analysis to further clarify the independent risk factors for vertebral body refracture after PKP. Survival analysis was performed using the time of vertebral refracture after PKP as the end time of follow up, the occurrence of refracture after PKP as the endpoint event, and the presence or absence of degenerative lateral curvature as a variable factor.@*RESULTS@#All 228 patients were followed up for 1.8 to 63.6 months with an average of (28.8±15.6) months, and the refracture rate was 10.5%(24/228). There were statistically significant differences between two groups in age, number of operative vertebral bodies, whether combinedwith degenerative scoliosis and whether anti osteoporosis treatment (@*CONCLUSION@#Combined scoliosis is an independent risk factor for refracture after OVCFs vertebroplasty, and it is also a possible high-risk factor for refracture after surgery.

ABSTRACT

BACKGROUND@#Generic drugs are bioequivalent to their brand-name counterparts; however, concerns still exist regarding the effectiveness and safety of generic drugs because of small sample sizes and short follow-up time in most studies. The purpose of this study was to evaluate the long-term antihypertensive efficacy, cost-effectiveness and cardiovascular outcomes of generic drugs compared with brand-name drugs.@*METHODS@#In a multicenter, community-based study including 7955 hypertensive patients who were prospectively followed up for an average of 2.5 years, we used the propensity-score-matching method to match the patients using brand-name drugs to those using generic drugs in a ratio of 1:2, 2176 patients using brand-name drugs and 4352 patients using generic drugs.@*RESULTS@#There were no significant differences between generic drugs and brand-name drugs in blood pressure (BP)-lowering efficacy, BP control rate, and cardiovascular outcomes including coronary heart disease and stroke. The adjusted mean (95% confidence interval [CI]) of systolic BP (SBP)-lowering was -7.9 mmHg (95% CI, -9.9 to -5.9) in the brand-name drug group and -7.1 mmHg (95% CI, -9.1 to -5.1) in the generic drug group after adjusting for age, sex, body mass index, number of antihypertensive drugs and traditionally cardiovascular risk factors. Among patients aged <60 years, brand-name drugs had a higher BP control rate (47% vs. 41%; P = 0.02) and a greater effect in lowering SBP compared with generic drugs, with the between-group difference of 1.5 mmHg (95% CI, 0.2-2.8; P = 0.03). BP control rate was higher in male patients using brand-name drugs compared with those using generic drugs (46% vs. 40%; P = 0.01). Generic drugs treatment yielded an average annual incremental cost-effectiveness ratio of $315.4 per patient per mmHg decrease in SBP compared with brand-name drugs treatment.@*CONCLUSIONS@#Our data suggested that generic drugs are suitable and cost-effective in improving hypertension management and facilitating public health benefits, especially in low- and middle-income areas.

ABSTRACT

Genetic as well as genomic study has advanced the development of precision medicine. We are marching on the road for right patients who are receiving more and more right treatment at right time. In hypertension field, precision medicine is available, actionable and affordable. First and the most practical advancement is monogenic hypertension, the disease-genes have been found for at least 17 types of monogenic hypertension. These patients can be precisely treated according to their carried gene mutation. Secondly, pharmacogenetic and pharmacogenomic guided anti-hypertensive drug selection, very promising but lack of clinic outcome data to support widely clinical application. Majority of hypertension are due to multiple genetic and environmental factors. GWAS fund some genetic variants related to primary hypertension, but these variants can only be responsible for 1-10% of blood pressure variation. We have a long way to go in exploring the real cause of primary hypertension.

ABSTRACT

The main symptom of chronicprostatitis/chronic pelvic pain syndrome (CP/CPPS) include perineal pain or discomfort, lower urinary tract symptom, mental and psychological problems, and sexual dysfunction (SD). Numerous studies confirmed a higher probability than normal in people suffering from the CP/CPPS accompanied by SD. It was characterized by repeated attacks and difficulty in curing. As a heterogeneous syndrome, the available evidence fails to indicate its pathogenesis and first-line diagnosis and treatment. This article reviews the epidemiological characteristics, pathogenesis, diagnosis and treatment of CP/CPPS with SD, and further explores the combined treatment of UPOINT(S) clinical phenotype classification system and multimodal therapy.

ABSTRACT

Postoperative intra-abdominal adhesion is one of the most common complications in the postoperative period. Current remedies are very ineffective to prevent the pathological outcomes except steroid hormones. Rhynchophylline is deemed as a pharmacologically active component from traditional Oriental medicine Uncaria rhynchophylla (Miq.) Jacks. (Rubiaceae). This study was designed to investigate the preventative effect of rhynchophylline on the abdominal adhesions in rats. Rhynchophylline relieved the experimental abdominal adhesion and decreased the levels of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the blood serum in a dose-dependent manner. The levels of transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF) were reduced significantly in the peritoneal fluid. The potential mechanism of the activity is related to inhibition of the TGF-β1/Smad signaling pathway.

ABSTRACT

Objective To investigate the effect of the novel curcumin-loaded chitosan liposomes on rabbit alkaline burns. Methods Curcumin-loaded chitosan liposomes were prepared with a film method. The particle sizes, zeta potentials and encapsulation efficiencies of liposomes were determined. Rabbits were randomly divided into four groups: the physiological saline group, the blank chitosan coated liposomes group, the dexamethasone group, and the curcumin-loaded chitosan liposomes group. The rabbit corneal alkaline burn models were built and respectively processed with the above medicines. The corneal neovascularization (CNV) and proportion of corneal epithelium healing were analyzed with the slit-lamp microscope and digital photographs. The expression of vascular endothelial growth factor (VEGF) was examined with an immunohistochemical method. Results The curcumin-loaded chitosan liposomes had the particle size of 96.6±14.7 nm, with the average zeta potential of 58.8±2.3 mV, and the encapsulation efficiency of 51.41±1.1%. The CNV was effectively inhibited and the expression of VEGF decreased due to the curcumin-loaded chitosan liposomes and dexamethasone. Furthermore, the curcumin-loaded chitosan liposomes improved epithelial healing of corneal more effectively than dexamethasone. Conclusion The encapsulation efficiency of the curcumin-loaded chitosan liposomes was high. The effects of the curcumin-loaded chitosan liposomes on inhibition of CNV and improvement of healing of cornea epithelium were obvious. Curcumin-loaded chitosan liposomes are novel ophthalmic delivery formulations for the treatment of corneal alkaline burns.

ABSTRACT

Objective To investigate the effect of recombinant human bone morphogenetic protein 2 (rhBMP-2) on the osteogenic activities of human osteosarcoma cell line SaOS-2. Methods SaOS-2 cells were exposed to rhBMP-2 for 12,24,48 h at 0(control) ,2,20,200 μg/L, respectively. The mRNA expression of alkaline phosphatase(ALP) and bone gla(BCP) were detected by real time polymerase chain reaction. Results The mRNA expression of ALP and BGP of SaOS-2 cells increased gradually with rhBMP-2. The mRNA expression of ALP of the 20 μg/L group exposed for 48 h(1.60 ± 0.64), and the 200 μg/L group exposed for 12,48 h(1.70 ± 0.41, 1.80±0.19) were significantly higher than those of control (12 h: 0.80±0.25, 48 h: 0.74±0.21, allP<0.05). The mRNA expression of BGP of the 2 μg/L group exposed for 24 h(1.67 ± 0.33), the 20 μg/L group exposed for 12,24 h(2.42 ± 0.13,1.82 ± 0.14) and the 200 μg/L group exposed for 12,24 h(1.46 ± 0.11,1.24 ± 0.07) were significantly higher than those of control( 12 h: 1.01 ± 0.14, 24 h: 0.84 ± 0.12, all P< 0.05). Conclusions rhBMP-2 can promote the mRNA expression of ALP and BGP of SaOS-2 cells. They have a dose-response relationship, but represent a different dose-response effect.

ABSTRACT

<p><b>OBJECTIVE</b>To study the factors influencing mother-infant vertical transmission of hepatitis B virus (HBV).</p><p><b>METHODS</b>A total of 635 pregnant women with chronic hepatitis B or chronic asymptomatic HBV carriers were enrolled. The rate of HBV infection was compared between the infants born from the pregnant women of different HBV-DNA load, different ways of delivery and different liver functions at birth and 3 months after birth. The newborn infants were routinely injected with hepatitis B immunoglobulin (200 IU) and hepatitis B vaccine (10 μg) within 12 hrs of birth. The newborns presenting HBV infection within 24 hrs of birth by serum test were re-injected with hepatitis B immunoglobulin (200 IU) 14 days after birth.</p><p><b>RESULTS</b>The rate of HBV infection in infants with maternal HBV-DNA load >10(5) copies/mL was higher than in those with maternal HBV-DNA load ≤ 10(5) copies/mL at birth (14.4% vs 4.1%; P<0.01) and 3 months after birth (4.7% vs 0; P<0.01).The rate of HBV infection at 3 months was lower than at birth in both groups. The rate of HBV infection in infants born by natural labor was higher than in those born by caesarean birth at birth (P<0.05), however, by 3 months after birth, the rate of HBV infection between the two groups was similar. The rate of HBV infection was higher in infants born to chronic asymptomatic HBV carrier mothers than that in infants born to chronic hepatitis B mothers at birth (P<0.01), but there were no significant differences in the two groups 3 months later.</p><p><b>CONCLUSIONS</b>The maternal HBV-DNA load is correlated with the rate of HBV infection of infants. It might thus be an effective way to reduce the rate of HBV infection in infants by decreasing maternal HBV-DNA load. With the administration of hepatitis B immunoglobulin and hepatitis B vaccine, the delivery way and the liver function of pregnant women may not to be factors influencing mother-infant HBV vertical transmission.</p>

ABSTRACT

Benign prostate hyperplasia (BPH) and chronic prostatitis (CP) are common diseases in males, and BPH is often complicated by CP. This review focuses on the relationship of BPH with CP and their epidemiology, pathogenesis and clinical features. Patients with BPH or CP are more likely to be subjected to another disease. Inflammation may be involved in the development of BPH. Compared with simple BPH, patients with CP-complicated BPH have significantly higher scores on age, prostate weight, prostate volume, and IPSS. Some related therapies are also evaluated, such as selective use of the alpha1-receptor blocker, 5alpha-reductase inhibitor, antibiotics, ultrasound microbubble contrast agents, and so on.

<p><b>OBJECTIVE</b>Quantitative ultrasound (QUS) is a new method of evaluating Children's bone status, including bone mineral density and bone strength. The bone nutrition during fetal and early neonatal period is very important for the human bone development of whole life. The objective of this study was to evaluate the clinical application of QUS for newborn infants and to obtain the QUS data for normal neonates including premature infants.</p><p><b>METHODS</b>An ultrasound bone sonometer, Omnisense, produced by Sunlight company of Israel, was applied to measure the bone speed of sound (SOS) of tibia in 157 neonates including 68 premature infants in the first week of life.</p><p><b>RESULTS</b>(1) No significant difference in SOS was found between male (n = 88, SOS = 2968 +/- 115 m/s) and female infants (n = 69, SOS = 2956 +/- 105 m/s) (P = 0.524). The SOS of premature infants (n = 68, mean gestational age 33.0 +/- 2.5 weeks) and full-term infants (n = 89, mean gestational age of 39.4 +/- 1.3 weeks) were 2935 +/- 96 m/s and 2984 +/- 116 m/s, respectively, at birth and there was significant difference between them (P = 0.005). (2) There were significant differences of SOS in neonates who were born in different seasons (F = 4.377, P = 0.005); the significant difference remained (F = 3.933, P = 0.010) after the influences of gestational age and birth weight were eliminated. The SOS in neonates born in spring (March, April and May) and summer (June, July and August) were significantly lower than that of those born in autumn (September, October and November) and winter (December, January and February). The SOS in neonates born in summer was about 2.3% (75/2999) was lower than that of those born in winter. (3) Significant difference of SOS was observed between neonates with different birth weight [< 1500 g (n = 11), SOS = 2968 +/- 115 m/s; and > 2500 g (n = 86), SOS = 2980 +/- 113 m/s; P = 0.042]. (4) Significant correlations were found between SOS and gestational age (r = 0.270, P = 0.005), and between bone SOS and birth weight (r = 0.232, P = 0.015) in appropriate for gestational age (AGA) infants (n = 109); however, no such significant correlations were found in small for gestational age (SGA) infants or large for gestational age (LGA) infants. Multiple regression analysis showed that gestational age and the birth season were two important factors which may contribute to bone SOS of neonates at birth (n = 157, F = 8.515, P < 0.001, adjusted R(2) = 0.141), when the analysis was carried out with SOS as dependent variable and gestational age, birth weight, chronological age, calf length and the birth season as independent variables.</p><p><b>CONCLUSION</b>QUS is a new method which is suitable for evaluating the bone status of neonates and it is free of radiation, non-invasive, the machine is portable and easy to manipulate at infant bed side. The present study suggests the need for particular care for the bone status in premature infants and supplement of vitamin D in pregnant women.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To detect the mutations of autosomal dominant polycystic kidney disease gene 2(PKD2)in Chinese.</p><p><b>METHODS</b>The white blood cell genomic DNA from patients of 94 Chinese autosomal dominant polycystic kidney disease(ADPKD) pedigrees was isolated and amplified by polymerase chain reaction(PCR). The PCR products were analyzed by denaturing high-performance liquid chromatography(DHPLC). The samples with abnormal profiles were sequenced.</p><p><b>RESULTS</b>Eight mutations were identified, including 2 nonsense mutations, 2 deletion mutations,1 insertion mutation and 3 missense mutations. Two nonsense mutations occurred in exon 5(1249C-->T) and exon 13(2407C-->T),both resulted in a stop codon. The insertion was in exon 2(636-637 ins T),and the deletion mutations were in exons 12(2348-2351 del AGAA) and 13(2401 delete A),resulting in the reading frame shift. Three missense mutations were in exons 1(G568-->A),4(C964-->T),and 5(G1168-->A), which caused amino acid changes (190Ala-->Thr,322Arg-->Trp,390Gly-->Ser).</p><p><b>CONCLUSION</b>The method of DHPLC was used in detecting mutations successfully and 8 mutations in PKD2 were identified. It will be useful in the molecular diagnosis of ADPKD in advance of the cysts formation and birth.</p>
