ABSTRACT

ABSTRACT Background: Periodontal disease is reportedly associated with the risk of various systemic diseases, including pancreatic and lung cancers. However, its association with prostate cancer remains inconclusive. Herein, we explored the association of periodontal disease with the risk of prostate cancer through a meta-analysis. Materials and Methods: MEDLINE, Embase, Web of Sciences and Cochrane Library databases were searched for eligible publications up to April 2020. Multivariate adjusted risk estimates with corresponding 95% confidence intervals (CIs) were extracted and calculated using random- or fixed-effect models. Results: Nine cohort studies involving 3.353 prostate cancer cases with 440.911 participants were identified and included in the meta-analysis. We found that periodontal disease significantly increased the risk of prostate cancer by 1.40-fold (hazard ratio [HR]=1.40, 95% CI: 1.16-1.70; P=0.001; I2=76.1%) compared with normal condition. Interestingly, the risk of developing prostate cancer was not significant in patients treated with periodontal therapy (HR=1.22, 95% CI: 0.86-1.73; P=0.272; I2=65.2%). The results of subgroup analyses were also consistent and significant when stratified by study design and follow-up period, whereas conflicting results were observed in periodontal disease ascertainment stratification. These findings were robust as indicated by sensitivity analyses. Conclusions: Periodontal disease was associated with the increased risk of prostate cancer, whereas no significant association was observed in patients treated with periodontal therapy. Hence, the awareness and importance for maintaining oral health should be improved, and the underlying mechanisms linking periodontal disease and prostate cancer should be fully explored in future research.

ABSTRACT

@#[Abstract] Objective: To investigate the expression of human endogenous retrovirus subfamily H long terminal repeat associating protein 2 (HHLA2) in hepatocellular carcinoma (HCC) tissues and its correlation with the clinicopathological characteristics and prognosis of patients with HCC. Methods: Based on TCGA database, the correlation between HHLA2 mRNA expression and B7 family genes in human HCC tissues was analyzed. HHLA2 expression in 90 pairs of HCC tissues and their adjacent tissues was detected by tissue microarry and immunohistochemical staining. Wilcoxon rank sum test was used to compare the difference of HHLA2 expression between HCC tissues and its adjacent tissues. The chi-square test was used to analyze the relationship between HHLA2 expression in human HCC tissues and clinicopathological features of the patients. Kaplan-Meier survival analysis was performed to analyze the correlation between HHLA2 expression and patients’ overall survival (OS), and the Cox model was used to evaluate the prognostic value of different indices. Results: The expression level of HHLA2 mRNA in HCC tissues was correlated with B7 family CD274, C10orf54, PDCD1LG2, ICOSLG and CD276. The expression level of HHLA2 in HCC tissues was significantly correlated with tumor size (χ2=4.531, P<0.05). The OS of HCC patients with high HHLA2 expression was significantly shorter than that of the patients with lower HHLA2 expression (HR=1.878, 95%CI: 1.066-3.309, P<0.05). The COX model showed that tumor size (HR=2.493, 95%CI: 1.310-4.742, P<0.01) could be used as an independent risk factor for the prognostic prediction of the patients. Conclusion: HHLA2 is significantly correlated with the prognosis of HCC patients, and can be used as a potential target for HCC immunotherapy.

ABSTRACT

Objective:To explore the application effect of segmented teaching combined with Kirkpatrick model evaluation in the teaching of specialized nurses of peripherally implanted central venous catheter (PICC).Methods:A total of 60 trainees in the PICC specialized nurse training class in PICC Clinic of Cancer Hospital Affiliated to Nantong University from June 2020 to September 2020 were selected in the study, and they were randomly divided into a control group and a study group, with 30 nurses in each group. The control group conducted traditional training for PICC specialized nurses, and the research group used segmented teaching. After training, the Kirkpatrick model was used to evaluate the response level, learning level, behavior level and result level of the training effect of the two groups of PICC specialized nurses. SPSS 22.0 was used for t test and chi-square test. Results:Through the segmented teaching training, the evaluation results of the Kirkpatrick model showed that the effect of the PICC specialized nurse training was significantly better in the study group than that in the control group in terms of response level, learning level, behavior level and result level. The study group's satisfaction with the training program and teaching content scored higher than that of the control group, with statistically significance ( P<0.001). The research group nurses' mastery of theoretical knowledge and practical skills and humanistic care scores were higher than those of the control group, with significant differences ( P<0.001). After the training, the self-behavior assessment scores of the two groups increased, and the improvement of the research group was more obvious. When the nurses of the research group returned to the hospital clinical work after training, their professional identity, PICC teaching and guidance ability, treatment, nursing service quality, the recognition of patient and family members and the effectiveness of the department were improved to varying degrees, the corresponding measures could be carried out in the hospital, and the development of PICC technology was promoted. Conclusion:The combination of segmented teaching and Kirkpatrick model evaluation can effectively meet the training needs of PICC specialized nurses and make a full range of effect evaluations to improve the quality of PICC specialized nursing services.

ABSTRACT

Objective:To classify the symptom characteristics of young and middle-aged peritoneal dialysis patients and to explore the differences of demographic functional status and social function of patients with different symptom categories.Methods:A total of 179 peritoneal dialysis patients from 3 peritoneal dialysis centers in Shanghai were investigated from December 2019 to August 2020 by General Information Questionnaire, Peritoneal Dialysis Symptom Distress Scale. Latent class analysis was used to classify young and middle-aged peritoneal dialysis patients according to symptom characteristics. Multiple Logistic regression was used to explore the differences of demographic and disease characteristics of different categories of patients.Results:Peritoneal dialysis patients could be divided into three potential categories according to symptom characteristics ( P<0.05). According to the conditional probability of each category, they were named "low symptom group" (111 cases,62.0%), "high psychological-moderate physical symptom group" (22 cases, 12.3%), "high symptom group" (46 cases,25.7%). There were differences in working status ( OR=0.029, P<0.01), education level ( OR=152.799, P<0.01), duration ( OR=81.307, P<0.05), diabetic nephropathy ( OR=80.619, P<0.01) and CCI score ( OR=91.188, P<0.01) distribution among different potential categories of young and middle-aged peritoneal dialysis patients. Conclusions:There are three types of potential symptoms in young and middle-aged patients undergoing peritoneal dialysis. In clinical practice, medical staff should focus on the psychological status of young and middle-aged patients with low educational background and early stage of dialysis, and encourage them to return to work; at the same time, they should regularly evaluate the symptom burden of patients with diabetic nephropathy and high complication index peritoneal dialysis patients, in order to provide targeted intervention measures to prevent the progression of the disease.

ABSTRACT

The Chinese herbal medicines contained in Guipitang (GPT) were retrieved in the databases, including traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP), encyclopedia of traditional Chinese medicine (ETCM), bioinformatics analysis tool for molecular mechanism of traditional Chinese medicine (BATMAN-TCM), and database for associated traditional Chinese medicine, gene, and disease information using text mining (TCMGeneDIT), and the compounds and their potential targets were obtained. Disease enrichment analysis on the potential targets of GPT was carried out to obtain the diseases potentially treated by GPT using MetaCore. Disease enrichment results showed that the potential diseases treated by GPT included encephalopathy, gastrointestinal diseases, nutritional/metabolic diseases, tumors/cancers, cardiovascular system diseases, endocrine system diseases, immune system diseases, drug-related side effects/adverse reactions, and congenital/hereditary diseases. On these grounds, the diseases treated by GPT were reviewed. The results of the previous research on diseases treated by GPT were consistent with analysis results of network pharmacology. The modern applications of GPT clinically went beyond its original indications, but its applications were based on the clinical manifestation of qi and blood deficiency in the heart and spleen, presenting the characteristic of "same treatment for different diseases". This study is expected to provide a reference for the further research and development of GPT.

ABSTRACT

As the first line of defense between the intestinal environment and the outside world, the intestinal mucosal barrier is essential for maintaining the intestinal homeostasis. The intestinal mucosal barrier injury will change the intestinal permeability and allow bacterial translocation and the entry of endotoxins into blood, thus triggering a series of inflammatory responses, followed by the injury of related tissues and the aggravation of primary diseases. The spleen, the acquired foundation, is responsible for maintaining the internal and external balance of the body and resisting external evils. Its physiological function is similar to that of the intestinal mucosal barrier. Spleen deficiency easily leads to intestinal mucosal barrier dysfunction. Therefore, replenishing Qi, invigorating spleen, and restoring the efficacy of spleen and stomach qi in defensing and governing transportation and transformation are the keys to prevent and treat intestinal mucosal barrier injury. In recent years, studies have shown that the spleen-invigorating Chinese medicinals repair the intestinal mucosal injury by promoting the expression of intestinal epithelial tight junction proteins, regulating the intestinal immune function, microbial flora, and metabolites, and supplementing the intestinal nutrition, enabling them to gradually become a research hotspot. After reviewing the relevant articles published in China and abroad, this paper expounded the common syndrome types of traditional Chinese medicine (TCM), the changes in intestinal mucosal barrier induced by spleen deficiency, the repairing effects of spleen-invigorating Chinese medicinals on intestinal mucosal barrier injury, in order to provide some clues for the research on the treatment of intestinal mucosal barrier dysfunction-related diseases with spleen-invigorating Chinese medicinals.

ABSTRACT

Objective:To observe the effect of the tactile vibration feedback system on the balance and walking function of the unilateral transitional amputees with prostheses. Methods:From October, 2019 to November 2020, eleven unilateral transtibial amputees with prostheses were selected from our hospital. They performed daily activities for three hours wearing tactile vibration feedback system designed by our department. The patients were evaluated by Performance Oriented Mobility Assessment (POMA), gait analysis and outdoor 1000 meters complex road walking test before and after treatment. Results:The balance score of the POMA improved (Z = -2.264, P < 0.05), the gait score and total score of the POMA increased significantly (|t| > 6.249, P < 0.001) after treatment. Gait analysis showed that the step length of the affected side improved, the bilateral step time and double support phase shortened, and the walking speed increased (|t| > 2.250, |Z| > 2.756, P < 0.05) after installation. The outdoor 1000 meters complex road walking test showed that the total steps, energy consumption and time decreased (|t| > 2.412, |Z| > 2.045, P < 0.05). All the patients finished the trail, and no discomfort appeared. Conclusion:The tactile vibration feedback system could safely and effectively improve the balance and walking function of the unilateral transtibial amputees with prostheses.

ABSTRACT

OBJECTIVE: To analyze the relationship between the neurobehavioral functions of individuals exposed to low-level lead and the levels of serum copper-related proteins glutathione S-transferase M1(GSTM1), hypoxia inducible factor-1 alpha(HIF1α), cyclooxygenase 1(COX1) and metallothionein(MT), and to screen biomarkers for changes in neurobehavioral function caused by occupational lead exposure. METHODS: A total of 194 workers who exposed to low-level lead(lead-exposed group) and 120 workers without lead exposure(control group) were selected from a battery factory as the research subjects by judgment sampling method. The inductively coupled plasma-mass spectrometry was used to determine blood lead levels of the two groups, and the State of Mood Scale(POMS) was investigated to assess the emotional state. The computerized neurobehavioral evaluation system in Chinese version 3(NES-C3) was used to test the neurobehavioral ability index(NAI) of related indicators of learning memory and mental activity. Enzyme-linked immunosorbent assay was used to detect the levels of copper-related protein in serum. After using principal component analysis to extract the principal components of emotional state, learning memory and mental activity, multiple linear regression was used to analyze the influencing factors of neurobehavioral function. RESULTS: The blood lead level of the lead-exposed group was increased [(57.15±11.12) vs(177.86±80.04) μg/L, P<0.01], and the incidence of symptoms such as dizziness, memory loss, sleep disturbance, fatigue, weakness, cold sweats in extremities, cold extremities, tingling of extremities, tingling sensation in the distal extremities, tetany, instability of holding things, metallic taste in the mouth, nausea and vomiting, anorexia, constipation, abdominal distension, abdominal pain, toothache/tooth loosening were increased(all P<0.01) compared with the control group. Meanwhile, the scores of tension-anxiety, depression-dejection, fatigue-inertia, anger-hostility, confusion-bewilderment of POMS were increased(all P<0.01), and the scores of vigor-activity were decreased(P<0.01). The NAI of the lead-exposed individuals in the NES-C3 test of 6 indicators(series addition and subtraction, visual retention, memory scanning, listening to digital breadth, visual simple reaction time, target tracking) were lower than that of the control group(all P<0.01). The serum levels of GSTM1 and HIF1α of the lead-exposed group decreased(all P<0.01), and the COX1 and MT levels increased(all P<0.01) compared with the control group. The serum GSTM1, HIF1α, COX1 and MT of the lead-exposed group were correlated with their emotional state, learning and memory and mental activity to varying degrees(all P<0.05). The results of multiple stepwise linear regression showed that serum COX1 level was an independent influencing factor of emotional state(P<0.01), serum GSTM1, COX1 and lead working years were independent influencing factor of learning and memory(all P<0.05), and work length with lead exposure and alcohol consumption was an independent influencing factor of mental activity(all P<0.05). CONCLUSION: Low-level lead exposure can cause central nervous system symptoms in workers, and the change in neurobehavioral function and serum levels of copper-related proteins GSTM1, HIF1α, COX1 and MT. Serum levels of GSTM1 and COX1 can be used as candidate biomarkers for indicating neurobehavioral function caused by lead exposure.

ABSTRACT

OBJECTIVE@#To investigate the effect of glycolytic enzyme pyruvate kinase type 2 (PKM2) on the proliferation and apoptosis of human leukemia HL-60 cells.@*METHODS@#si-PKM2 plasmid was transfected into HL-60 cells (set as si-PKM2 group), and blank vector transfected cells were set as control group (si-Ctl group). The expression levels of PKM2 mRNA and protein in si-Ctl group and si-PKM2 group were detected by RT-qPCR and Western blot. CCK-8 cell detection kit was used to detect the proliferation ability of the cells in the two groups. Flow cytometry was used to detect the changes of cell cycle and apoptosis. Western blot and RT-qPCR were used to detect the changes of p-Akt and p-mTOR protein levels in PI3K/Akt/mTOR signaling pathway and the changes of glycolysis-related mRNA levels of the cells in the two groups. The changes in glucose consumption and lactic acid production of the cells were assayed. Over expressed PKM2, HL-60 cells were treated with PI3K inhibitor LY294002 or galactose, the changes in cell proliferation ability, cell cycle and apoptosis, as well as changes in glucose consumption and lactic acid production were detected.@*RESULTS@#Interfered by si-PKM2, mRNA and protein levels of PKM2 in si-PKM2 group significantly decreased, and proliferation ability of the cells was also reduced (P<0.05). After PKM2 knockdown, the cells were significantly blocked at G@*CONCLUSION@#PKM2 knockdown can inhibit the proliferation and induce apoptosis of HL-60 cells, and its molecular mechanism may be related to the PKM2-mediated PI3K/Akt/mTOR-glycolysis, which suggesting that PKM2 may serve as a molecular target for the prevention and treatment of leukemia.

ABSTRACT

OBJECTIVE@#To investigate the efficacy of self-made arthroscopic single channel in the treatment of carpal tunnel syndrome.@*METHODS@#Sixty patients with primary carpal tunnel syndrome treated from January 2014 to December 2019 were divided into arthroscopic group and traditional open operation group. There were 30 cases in arthroscopic group, including 12 males and 18 females, aged (47.5±4.5) years and the course of disease was (6.6±4.2) months. There were 30 cases in the traditional operation group, including 10 males and 20 females, aged (48.5±3.5) years, and the course of disease was (5.6±4.4) months. Both groups were unilateral. According to the anatomy of wrist joint and the characteristics of transverse carpal ligament and arthroscopy, the instruments including cannula, inner heart and hook knife were designed. The patients in two groups were treated with decompression of transverse carpal ligament using arthroscopy combined with self-made instruments and traditional open sergery. The incision length, operation time, intraoperative bleeding, hospitalization cost, hospitalization time and recovery time of the two groups were observed and compared. Boston Carpal Tunnel Questionnaire (BCTQ) score was used to evaluate the clinical efficacy of arthroscopy combined with self made instruments in the treatment of carpal tunnel syndrome.@*RESULTS@#Compared with the traditional group, the arthroscopic group had significant advantages in incision length, operation time, intraoperative bleeding and hospital stay, but the total cost of hospitalization was increased. The Boston score was significantly higher in the arthroscopic group than that in the traditional group at 1 month after operation, but not at 3 and 6 months after operation.@*CONCLUSION@#Arthroscopy combined with self-made instruments in the treatment of carpal tunnel syndrome is more reliable, minimally invasive and simplified than open surgery, but the patients should be clearly diagnosed and appropriately selected before operation to achieve satisfactory clinical effect.

ABSTRACT

OBJECTIVE@#To explore the influencing factors in children with chronicity immune thrombocytopenia (ITP), and to provide basis for judging the prognosis and treatment in children with ITP.@*METHODS@#The clinical data of children with ITP admitted to The Second Affiliated Hospital of Anhui Medical University in the past 5 years were retrospectively analyzed and followed up for more than 1 year. According to the inclusion criteria, the eligible cases (328 cases in total) were selected and collected through medical record system retrieval, outpatient clinic and telephone follow-up. Independent influencing factors affecting the prognosis of children with ITP were obtained through single-factor and multi-factor logistic analysis, and their predictive value for the prognosis of ITP in children were evaluated.@*RESULTS@#Of 328 children with ITP, 208 were newly diagnosed with ITP (64%), 54 were persistent ITP (16%), 66 were chronic ITP (20%), and the remission rate within 1 year was 79.9%. The results of univariate analysis showed that, age, pre-morbidity history of infection and vaccination, antinuclear antibodies, initial absolute lymphocyte count(ALC) and treatment options were related to the prognosis of the children (P<0.05). Multivariate analysis showed that the history of infection and vaccination before onset, initial treatment options, and ALC at the time of initial diagnosis were independent factors affecting the prognosis of children with ITP (P<0.05). The time for platelet recovery to 100×10@*CONCLUSION@#The initial treatment plan combined with IVIG can reduce the occurrence of chronicity in children with ITP, and its efficacy is better than that of the single corticosteroids group (the platelet recovery time is shorter); history of preceding infection or vaccination, ALC at the time of initial diagnosis are independent factors affecting the prognosis of children with ITP, and the combination of the two shows a better predictive value for the prognosis.

ABSTRACT

To evaluate the effects of Hydroxypropyl methylcellulose acetate succinate(HPMCAS MF) on absorption of silybin(SLB) from supersaturable self-nanoemulsifying drug delivery system which was pre-prepared at the early stage experiment. The cell toxicity of self-emulsifying preparation was evaluated by the MTT method, and the in vitro membrane permeability and absorption promoting effect of the self-emulsifying preparation were evaluated by establishing a Caco-2 cell monolayer model. The in vivo and in vitro supersaturation correlation was evaluated via the blood concentration of SLB. The results of MTT showed that the concentration of the preparation below 2 mg·mL~(-1)(C_(SLB) 100 μg·mL~(-1)) was not toxic to Caco-2 cells, and the addition of polymer had no significant effect on Caco-2 cells viability. As compared with the solution group, the transport results showed that the P_(app)(AP→BL) of the self-emulsifying preparation had a very significant increase; the transport rate of silybin can be reduced by polymer in 0-30 min; however, there was no difference in supersaturated transport between supersaturated SLB self-nanoemulsion drug delivery system(SLB-SSNEDDS) and SLB self-nanoemulsion drug delivery system(SLB-SNEDDS) within 2 hours. As compared with SLB suspension, pharmacokinetic parameters showed that the blood concentration of both SLB-SNEDDS and SLB-SSNEDDS groups were significantly increased, and C_(max) was 5.25 times and 9.69 times respectively of that in SLB suspension group, with a relative bioavailability of 578.45% and 1 139.44% respectively. C_(max) and relative bioavailability of SLB-SSNEDDS were 1.85 times and 197% of those of SLB-SNEDDS, respectively. Therefore, on the one hand, SSNEDDS can increase the solubility of SLB in gastrointestinal tract by maintaining stability of SLB supersaturation state; on the other hand, the osmotic transport process of SLB was regulated through the composition of its preparations, and both of them could jointly promote the transport and absorption of SLB to improve the oral bioavailability of SLB.

ABSTRACT

To verify the appropriate preparation process of extracts for the solid substance benchmark of Linggui Zhugan Decoction. The extracts were prepared by different preparation processes, namely the traditional process(process 1), the extract combined with volatile oil separated from traditional process extract liquid(process 2), the modern secondary reflux extraction process(process 3) and the process that volatile oil was extracted first, then prepared according to the traditional process, and combined with extract(process 4); based on the characteristic spectrum, index components of cinnamaldehyde, glycyrrhizin, ammonium glycyrrhizinate, cinnamic acid, and the dry extract rate of process 1, the differences and similarities of four extracts were compared. The results showed that the similarity of the characteristic spectrum of process 2, process 4 and process 1 were all greater than 0.97, while there was no significant difference for the content of 4 quality control components and dry extract rate; the similarity of the characteristic spectrum of process 3 and process 1 was 0.91, the absolute peak area of 13 out of 21 peaks and the relative peak area of 7 peaks increased significantly, and the content of 3 out of 4 quality control components and dry extract rate also significantly increased. In conclusion, the material standards of extracts by the process 2 and 4 are consistent with that of the traditional process, so the two processes are suitable.

ABSTRACT

Protein kinase C(PKC) is a type of protein kinase widely involved in cell proliferation and development, but the developmental mechanism in the gonads of androgynous animals is still unclear. In order to explore the role of protein kinase C in the development of Whitmania pigra germ cells, the Wh. pigra PKC(Wp-PKC) gene was cloned, bioinformatics analysis was conducted, and fluorescent quantitative PCR was used to analyze the expression of female and male gonads. The results showed that:(1)The cloned Wp-PKC had a full length of 2 580 bp, a relative molecular weight of 76 555.19, and contains an open reading frame encoding 670 amino acids, Wp-PKC was closely related to Danio rerio PKC-α and rat PKC-γ. The similarity of amino acid sequence was 55% and 58%.(2)The protein encoded by Wp-PKC had no signal peptide and was a hydrophilic protein. The secondary structure is mainly composed of random coils, α-helices, extended chains, folds and folds, with the largest proportion of random coils and α-helices. Wp-PKC protein does not contain a transmembrane domain. Multiple sequence alignment and domain prediction analysis show that Wp-PKC contains 4 conserved domains of classical protein kinase C.(3)Fluorescence quantitative results showed that the expression of Wp-PKC in Wh. pigra gonads was positively correlated with the development of germ cells, and the expression in male gonads was significantly higher than that in female gonads. In summary, Wp-PKC is a classic PKC, and Wp-PKC may promote the development of Wh. pigra, especially the development of male gonads, and provide references for further research on the developmental mechanisms of Wh. pigra.

ABSTRACT

OBJECTIVES@#This study aimed to assess the influence of different types of rapid maxillary expansion on root resorption (RR).@*METHODS@#Literature searches were carried out electronically in five English and two Chinese databases. Randomized controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies, and case-control studies were included. The data were extracted by three authors. The risk of bias in the RCTs and nonrandomized studies were assessed in accordance with corresponding scales.@*RESULTS@#Among the 400 articles identified, seven were included for the final analysis. Three studies were graded as high value of evidence, while two and another two studies were graded as moderate value and low value, respectively. According to the available evidence, the tooth-borne maxillary expansion caused more obvious RR of anchorage teeth than the bone-borne one. In addition, the Haas-type palatal acrylic pads could not effectively reduce the degree of RR. The difference in the design of the retainer between the tooth-borne maxillary expansion (the use of a band or wire framework to connect the anchorage tooth) did not cause the difference in the incidence and degree of RR.@*CONCLUSIONS@#Clinical evidence suggested that bone-borne maxillary expansion may decrease the amount of RR, while the amounts of resorption did not significantly differ between Haas and Hyrax and between different retainer types of Hyrax.

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.
