Objective To evaluate the clinical effects and immune function of shenqi 11 flavor capsule as an adjuvant treatment in advanced NSCLC patients during chemotherapy.Methods 58 cases of advanced NSCLC were divided into two groups by mean of digital random table method,with 29 patients in each group.GP scheme chemotherapy was applied to patients in group B,using gemcitabine (1000 mg/m2) on the 1st and 8th day intravenously (procedure should be finished within 30 minutes) and cisplatin (75 mg/m2) on the 1st day intravenously.Each cycle was 3 weeks,two cycles in total.Same scheme was applied to patients in group A and with an addition of shenqi 11 flavor capsule(1.65 g/time,3 times/d) throughout the whole procedure of chemothrapy.Recent curative effect,life quality,toxic reactions and changes in immune indexes of both groups were observed.Results Short-term response rate in group A was 48.27％ and 41.38％ in the group B (x2=0.279,P＞0.05),which showed no significant differences between the two groups.Toxic reactions such as leukopenia,hematochrome decrease and gastrointestinal reactions in the group B were significantly severe compared to group A after chemotherapy(x2 were 4.678,4.549 and 4.687 respectively,P＜0.05).As for immune indexes after chemotherapy,CD3+ (55.21 ± 3.28) ％,CD4+ (38.84±5.13) ％,CD8+ (29.86±4.83) ％,CD4+/CD8+( 1.29± 0.17) and NK cells (20.12± 2.11 ) ％in the group B indicated significant differences compared to those in group A[(62.96±4.12)％、(45.21±3.43)％、(25.23±2.79)％、(1.82±0.21)、(25.78±3.36)％],(P＜0.05).The life quality was 58.62％ in group A and 31.03％ in the group B,which showed significant difference (x2=4.462,P＜0.05).Conclusion Shenqi 11 flavor capsule as an adjuvant treatment in advanced NSCLC patients during chemotherapy can not only improve life quality of patients,alleviate the symptoms,but also enhance their immune function.

Objective To assess the efficacy and safety of lanthanum carbonate in treatment of hyperphosphatemia in end-stage renal disease (ESRD).Methods Randomized controlled trails of lanthanum carbonate in treatment of hyperphosphatemia in ESRD patients were searched in the database of MEDLINE,Cochrane Central Register of Controlled Trials,EMBASE,CNKI,Wanfang database.Data extracted from the literatures were analyzed with the Cochrane Collaboration's RevMan 5.1 software.Results Lanthanum carbonate group was similar with calcium carbonate group in treating hyperphosphatemia[RR =1.00,95 ％ CI (0.92-1.09),P =0.97],and more effective than placebo [RR=4.69,95％ CI (2.63-8.39),P＜ 0.01] (intervention dose≤ 1500 mg) and [RR =18.92,95％ CI (7.42-48.22),P ＜ 0.01] (intervention dose ＞ 1500 mg).In comparison with calcium carbonate group,the incidence of hypercalcinemia of lanthanum carbonate group was lower [RR =0.06,95 ％ CI (0.01-0.72),P =0.03],while the incidence of nausea [RR =1.80,95 ％ CI(0.70-4.64),P =0.22],vomiting [RR =3.94,95％ CI (0.45-34.38),P=0.22] and constipation [RR=0.82,95％ CI (0.49-1.37),P=0.45] were similar.The incidence of nausea and vomiting of lanthanum carbonate group were similar with placebo,with lower incidence of constipation [RR =0.19,95 ％ CI (0.06-0.59),P ＜ 0.01].Conclusions The efficacy of lanthanum carbonate in treating hyperphosphatemia is similar with calcium carbonate.The incidence of hypercalcinemia of lanthanum carbonate is lower than that of calcium carbonate,and the incidence of gastrointestinal adverse effect such as nausea,vomiting and constipation are similar with calcium carbonate.

A series of surveillance and management actions was taken to minimize out-of-plan re-operations. These actions include: 1) Building and completing the surveillance and management mechanism against unplanned re-operations; 2) Building a real-time surveillance and reporting mechanism; 3) Enhancing quality control and continuous improvement at the operating departments; 4) Enhancing the supervision on regulations implementation by quality control departments of the hospital; 5) Enhancing quality control for medical records; 6) Building a feedback mechanism for surveillance results; 7) Building a penalty and reward mechanism. Efforts for one year and a half on such surveillance and management proved successful, as the incidence of out-of-plan re-operations fell from 1.7% before these actions to 1.0% afterwards.

Objective To investigate the effect of angiotensin Ⅱ (Ang Ⅱ) type 1 receptor blocker (ARB) on 12-lipoxygenase (12-LO) activity and P-cadherin expression in type 2 diabetic rat glomeruli.Methods Podocytes were stimulated by 107 mol/L Ang Ⅱ for 24 hours.12(S)-HETE (1mg· kg 1 · d-1) and Ang Ⅱ (400 ng· kg-1· min-1) were infused to rats by osmotic mini-pump for 1 week and 2 weeks respectively.Rats fed with high fat diet received low dose streptozotocin (STZ) to make type 2 diabetes and divided into 2 groups:low dose STZ (DN group),low dose STZ + ARB treatment (Losartan group).Rats fed with regular chow were used as control group.All the rats were sacrificed after 6 weeks.Urine,blood,kidney cortical tissue and isolated glomeruli by sieving method were collected at the end of study respectively.ELISA,RT-PCR and Western blotting for related target were performed respectively.Results Ang Ⅱ increased 12(S)-HETE levels in podocytes and glomeruli (all P ＜ 0.01).Ang Ⅱ levels in the glomeruli were significantly increased by 12(S)-HETE stimulation (P ＜0.01).Blood glucose,kidney/body weight and 24 hour urinary protein were increased in DN group compared with that in control group (all P ＜ 0.01).However,urine protein,Kidney/body weight were decreased in Losartan group compared with DN group (all P ＜ 0.05).Increment of 12(S)-HETE content and decrement of P-cadherin expression were observed in DN glomeruli compared with that in control group(all P ＜ 0.01).These abnormalities were prevented by administration of the losartan (all P ＜ 0.05).Conclusions Ang Ⅱ can down-regulate glomerular P-cadherin expression via activation of 12-LO.ARB can ameliorate the progression of DN via up-regulation of glomerular P-cadherin through inhibition of 12-LO activation in type 2 DN rats.

Objective To investigate the effects of 12-lipoxygenase (12-LO) and angiotensin Ⅱ (Ang Ⅱ) on the CIP/KIP family of cyclin-dependent kinase inhibitors (CKIs) p21,p27 and p57 related to cell hypertrophy.Methods Mesangial cells were treated with high glucose for 24 hours and 48 hours respectively.12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] and Ang Ⅱ were infused to rats by osmotic mini-pump for 1 week and 2 weeks respectively.Rats fed high fat diet were received low dose streptozotocin (STZ) to make type 2 diabetes (DN).The rats were divided into normal control group,DN group,DN+Ang Ⅱ type 1 receptor blocker (ARB) group or 12-LO inhibitor (CDC) group.DN+ARB rats were treated by losartan for 6 weeks,and DN+CDC rats were treated for 8 weeks.Urine albumin and protein expressions of p21,p27 and p57 were detected by ELISA and Western blotting respectively.Glomeruli injury and expressions of p21 and p27 were detected by PAS staining and immunohistochemistry respectively.Results High glucose increased p21 and p27 protein expression in mesangial cells significantly compared with the relative control (all P ＜ 0.05),but had no effect on p57.Ang Ⅱ increased p27 protein expression in gloneruli significantly (P ＜ 0.05),but had no effect on p21 and p57 protein expression.12(S)-HETE increased both p21 and p27 protein expression in glomeruli significantly (all P ＜ 0.05),but had no effect on p57 protein expression.Blood glucose,kidney/body weight,urinary protein,and glomerular p21 and p27 protein expressions were increased in DN group (all P ＜ 0.05) compared with those in control group,with little change of p57 protein expression (P ＜ 0.05).Moreover,glomerular hypertrophy and extra cellular matrix accumulation were observed in DN group.However,urine protein,kidney/body weight,renal injury,but not blood glucose,were decreased in DN+ARB group and DN+CDC group compared with DN group respectively (P＜ 0.05).Further DN+CDC rats had decreased both p21 and p27 protein expressions in glomeruli,but DN+ ARB rats only had decreased p27 protein expression (all P ＜ 0.05).Conclusions 12-LO may induce both p21 and p27 protein expression in DN glomeruli,but Ang Ⅱ may induce only p27 expression.

Objective To study the clinical efficacy of Nd∶YAP laser in the treatment of acute localized pericardial periodontitis. Methods A total of 120 patients with acute localized pericardial periodontitis were randomly divided into 3 groups, including Nd∶YAP laser group, minocycline group and control group (iodine glycerol group). All patients were underwent pretreatment of intracrevicular washing with 3.0％hydrogen peroxide and normal saline alternately. After the pretreatment, the patients in the Nd∶YAP laser group were given 3 min local Nb:YAP laser irradiation (1 time/d for 3 times), in the minocycline group were injected with minocycline hydrochloride ointment (1 time), and in the control group were treated with 2％iodine glycerol (1 time/d for 4 times) in gingival sulcus. One day after the treatment, the gingival index (GI), pain visual score (VAS), and opening degree of all patients were recorded, and the therapeutic effect was observed 5 days after the treatment. Results Compared with the minocycline group and the control group (iodine glycerol group), the GI value and VAS value of the Nd∶YAP laser group decreased and the openmouthed size increased (all P<0.05). At 5 days after the treatment, the patients in the Nd∶YAP laser group and the minocycline group had significant improvement in local gingival sulcusinflammation, and the total effective rate was 90％and 85％, which was significantly better than the control group (all P<0.05) and no significant difference in efficacy between the two groups (P>0.05). Conclusions The Nd∶YAP laser treatment inacute wisdom tooth pericoronitis can significantly reduce pain and improve openmouthed size, and has a good clinical efficacy.

Objective To evaluate the damage of von Willebrand factor (vWF) induced by shear stress in BPX-80 centrifugal blood pump, and determine whether it can be used as a reference pump for vWF damage research. Methods An in vitro hemolysis test platform was established according to the ASTM standards. The BPX-80 centrifugal blood pump was tested for 8 hours by using fresh porcine blood. The hemolysis level and vWF damage of hourly blood samples were then evaluated and compared with the static control group. ResultsThe hemolysis index of BPX-80 was stable and low during the test; vWF polymer with high molecular weight had a small amount of degradation, and showed no significant difference compared with the static control group; there was no significant change in the concentration of vWF antigen, which was basically consistent with the trend of the static control group. Conclusions BPX-80 centrifugal blood pump has good blood compatibility and can be used as the reference pump for vWF damage and hemolysis evaluation, thereby providing guidance for the design and optimization of new blood pumps.

Objective: To investigate the effects and mechanisms of microRNA-146a (miR-146a) on osteogenic differentiation of human periodontal ligament cells (hPDLC) stimulated by lipopolysaccharide (LPS) of Porphyromonas gingivalis (Pg). Methods: hPDLC were cultured in vitro and induced to the phase of osteogenic differentiation. These cells were divided into five groups: non-osteogenic differentiation cells, osteogenic differentiation cells, osteogenic differentiation cells treated with Pg LPS, osteogenic differentiation cells treated with Pg LPS and miR-146a mimic, osteogenic differentiation cells treated with Pg LPS and miR-146a negative control. Osteogenic markers and mineralization were detected via quantitative real-time PCR (qPCR) and alizarin red staining, respectively. Meanwhile, non-radioactive transcription factor assay was applied to explore the nuclear activity of nuclear factor kappa B (NF-κB) p65 in nuclear extracts of hPDLC. Results: Compared with cells of osteogenic differentiation in non-LPS-stimulated groups, Pg LPS could decrease the markers of osteogenic differentiation of hPDLC such as collagen Ⅰ (Col-Ⅰ), alkaline phosphatase (ALP), Runt-related transcription factor-2 (RUNX2) and osteocalcin (OCN) (P<0.05), inhibit mineralization, and stimulate NF-κB p65 nuclear activity expression (non-LPS stimulated group: 1.023±0.217, LPS stimulated group: 6.252±0.613, P=0.008). However, compared with cells in Pg LPS/miR-146a negative control group, miR-146a increased Col-Ⅰ (P=0.007) and OCN (P=0.049) mRNA expression, rather than ALP (P=0.167) and RUNX2 (P=0.580) at day 3; miR-146a also upregulated mRNA levels of Col-Ⅰ, ALP, RUNX2 and OCN (P<0.05) at day 7 and day 14, and enhance mineralization. Meanwhile, miR-146a mimic could decrease the nuclear activity of NF-κB p65 induced by Pg LPS in hPDLC (miR-146a: 2.427±0.354, negative control: 5.863±0.482, P=0.019). Conclusions miR-146a could reverse the inhibitory effects of Pg LPS on osteogenic differentiation of hPDLC through enhancing the expression of osteogenic markers and decreasing inflammatory pathway in hPDLC.

Objective: To analyze the trends and hotspots in research related to microbiomes and microbes of dental caries; in addition, the study seeks to provide a reference for caries research. Methods: We searched the Web of Science Core Collection (WOSCC) to extract relevant literature in the field of microbiomes and microbes of dental caries published from 2014 to 2023. We used bibliometric visualization evaluation methods such as CiteSpace to conduct visualized analysis of factors that include the number of publications, journals, countries, authors, institutions, co-cited references, and keywords. Results: A total of 3 192 references were extracted, including 2 664 articles and 528 reviews. The number of annual publications is increasing. The United States and China lead the number of publications, with the United States demonstrating a greater capacity for international collaboration. The top 10 journals in percentage of literature are mainly in the field of dentistry followed by the field of microbiology. The author cooperation networks with the highest number of publications include the network led by Zhou Xuedong of Sichuan University, and the network led by Xu Hockin H.K and Weir Michael D of the University of Maryland, Baltimore. The research on microbiomes and microbes of dental caries focuses on the cariogenic toxicity and interaction of microorganisms, oral microbiomes, and the relationship between dental caries and systemic diseases. The articles with high citation frequency mainly involve topics such as dental caries, oral biofilm, oral microbiota, and Streptococcus mutans. Keyword research showed that “dental caries,” “Streptococcus mutans,” “bacteria,” “dental plaque,” and “antibacterial activity” have been the primary focus of research in the last decade. The number of keywords, such as “health” and “oral health,” is on the rise. The latest emergence of “gut microbiome/microbiota” suggests that the oral gut microbiome axis is at the forefront of research in this field, and researchers’ focus is gradually shifting toward the connection between dental caries and systemic diseases. Conclusion Over the last decade, the number of publications in the field microbiomes and microbes of dental caries has increased annually. This research trend will be the multi-omics of the overall oral microbiome, and new research methods and techniques will contribute to the field of cariology.
