Objective To investigate the tendency of diapause symptoms in breast cancer patients during their chemotherapy. Method Sixty-four breast cancer patients with chemotherapy participated in the study by using Pittsburgh sleep quality index (PSQI), the cancer fatigue scale (CFS), the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) to assess their sleep, fatigue, anxiety and depression at every first day from the second course to sixth one of chemotherapy. Results The diapause symptoms including fatigue, sleep disorders, anxiety and depression varied with the therapeutic course progressing. The conditions in sleep quality, fatigue and depression were the poorest at the diapause of the fourth course and the condition of anxiety was the poorest at the diapause of the third course. Conclusion The medical staff should attach importance to the patients'physical and mental problems brought by the process of chemotherapy, strengthen the regulation of psychosomatic symptoms during chemotherapic diapause, and give reasonable control and intervention before the symptoms deteriorating.

OBJECTIVETo compare the therapeutic effects of pricking blood therapy combined with acupuncture and routine western medicine on herpes zoster.

METHODSTwo hundred and forty cases were randomly divided into 2 groups, 120 cases in each group. The treatment group were treated with acupuncture combined with pricking blood therapy on the point with the most pain, and cupping and surround needling; the control group with external application and oral administration of Aciclovir plaster and Aciclovir tablets, respectively. Their therapeutic effects were compared.

RESULTSThe total effective rate was 92.5% in the treatment group and 55.8% in the control group with a very significant difference between the two groups (P < 0.01). The time of producing killing pain, stopping vesication and scabbing in the treatment group was shorter than that in the control group.

CONCLUSIONThe pricking blood therapy combined with acupuncture is an effective therapy for herpes zoster.

Abstract: Objective　To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods　A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results　There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions　The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

OBJECTIVETo study the inhibitory effect of paeoniflorin (PAE) on TNF-α-induced TNF receptor type I (TNFR1)-mediated signaling pathway in mouse renal arterial endothelial cells (AECs) and to explore its underlying molecular mechanisms.

METHODSMouse AECs were cultured in vitro and then they were treated by different concentrations PAE or TNF-α for various time periods. Expression levels of intercellular cell adhesion molecule-1 (ICAM-1) were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 6-h TNF-α 30 ng/mL), the low dose PAE group (cultured by 2-h PAE 0.8 μmo/L plus 6-h TNF-α 30 ng/mL), the middle dose PAE group (cultured by 2-h PAE 8 μmol/L plus 6-h TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 6-h TNF-α 30 ng/mL) with Western blot analysis. Nuclear translocation of transcription factor NF-κB (NE-κB) was detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 45-mm TNF-α 30 ng/mL), and the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 45-min TNF-α 30 ng/mL) by immunofluorescent staining. Expression levels of the phosphorylation of extracellular signal-regulated (protein) kinase (ph-ERK) and p38 (ph- p38) were detected in the normal group (cultured by serum-free culture media) and the high dose PAE group (2-h PAE 80 μmol/L culture) by Western blot. NF-κB inhibitor-α (IκBα) protein expressions were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 30-min TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 30-min TNF-α 30 ng/mL), the p38 inhibitor group (SB group, pretreatment with SB238025 25 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min), the ERK inhibitor group (PD group, treated by PD98059 50 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min) by Western blot.

RESULTSCompared with the normal group, ICAM-1 protein expression levels obviously increased (P < 0.01). Compared with the TNFα group, ICAM-1 protein expression levels were obviously inhibited in the high dose PAE group (P < 0.05). Protein expression levels of ph-p38 and ph-ERK were obviously higher in the hIgh dose PAE group (P < 0.05). Compared with the normal group, IκBα protein expression levels obviously decreased in the TNF-α group (P < 0.01). Compared with the TNFα group, TNF-α-induced IκBα degradation could be significantly inhibited in the high dose PAE group (P < 0.01); the inhibition of PAE on IκBα degradation could be significantly inhibited in the SB group (P < 0.05). NF-κB/p65 signal was mainly located in cytoplasm in the normal group. NF-κB/p65 was translocated from cytoplasm to nucleus after stimulated by 45 min TNF-α in the TNF-α group, while it could be significantly inhibited in the high dose PAE group.

CONCLUSIONSPAE inhibited TNF-α-induced expression of lCAM-1. Its action might be associated with inhibiting TNFR1/NF-κB signaling pathway. p38 participated and mediated these actions.

BACKGROUNDIn a previously identified locus linked to hypertension on chromosome 15q, we identified three blood pressure candidate genes: insulin-like growth factor 1 receptor gene (IGF1R), myocyte specific enhancer factor 2A gene (MEF2A), and paired basic amino acid cleaving enzyme 4 gene (PACE4). In this study, we tested their associations with hypertension using haplotype analysis.

METHODSA total of 288 unrelated individuals, including 163 high diastolic blood pressure (DBP) subjects and 125 normal DBP subjects were enrolled in this case-control study. Twenty single nucleotide polymorphisms (SNPs) in the three genes were genotyped using polymerase chain reaction followed by restriction enzyme digestion. Haplotype analysis was accomplished in the following stages: (1) pair-wise linkage disequilibrium test among SNPs on the same gene was performed to explore blocks in which recombination is very unlikely to happen; (2) Estimation-Maximization algorithm was applied to estimate haplotype frequencies in each block; (3) the chi-square test was used to examine the specific haplotype difference, and a permutation test was used to examine the overall haplotype profile difference between cases and controls in each block.

RESULTSAn estimated haplotype "CCCCG" frequency in the haplotype block on the PACE4 gene was significantly higher in high DBP cases than in controls (P < 0.01). The overall estimated haplotype profile in this block was also significantly different between the cases and the controls (P < 0.001). This association indicates.

CONCLUSIONSThis study for the first time demonstrated that PACE4 gene may play an important role in the regulation of DBP. This association indicates that variations influencing DBP resides in or near this genomic region.

BACKGROUNDInflammation is a major cause of restenosis after coronary stenting. Intercellular adhesion molecule-1 (ICAM-1) is an important adhesion molecule that plays a key role in the tight adhesion between leukocytes and vascular endothelium. The object of this study was to investigate the association between the K469E polymorphism of the ICAM-1 gene and restenosis after coronary stenting in North Chinese population.

METHODSThe ICAM-1 K469E polymorphism was genotyped using polymerase chain reaction-restriction fragment length polymorphism method in 124 patients who had undergone coronary stenting and coronary angiography at least 3 months earlier. Information on clinical risk factors and procedure-related data were also collected.

RESULTSOf 124 enrolled patients in total, there were 72 cases of in-stent restenosis. The restenosis rate in this population was 58.1%. The frequencies of the three possible genotypes of the ICAM-1 K469E polymorphism were: KK genotype 50.8%, EE genotype 41.9%, and EK genotype 41.9%. Among restenosis patients, the frequency of the KK genotype was 58.3% and the frequency of E allele carriers was 41.7%. Among non-restenosis patients, the frequency of the KK genotype was 40.4%, and the frequency of E allele carriers was 59.6%. The distribution of these two genotype groups between restenosis and non-restenosis patients was significantly different (P = 0.049). Using multivariate logistic regression, the difference between the two groups was more apparent. The odds ratio of KK homozygotes vs E allele carriers was 2.6, with 95% confidence interval 1.2 - 5.8 (P = 0.018). After grading of risk factors, we found that the KK genotype was a stronger predictor of in-stent restenosis in obesity or hyperlipemia patients, with an odds ratio of 9.3 and 3.7, respectively (P < 0.05).

CONCLUSIONIn our study population, KK homozygotes of the ICAM-1 codon 469 mutation had a higher risk of restenosis after coronary stenting, especially in the case of obese or hyperlipemia patients.

BACKGROUNDThe emergence of drug-eluting stents (DES) has dramatically reduced the incidence of in-stent restenosis. This study was conducted to evaluate the safety and efficacy of sirolimus-eluting cobalt-chrome stents (Firebird 2) for treating patients with coronary artery disease.

METHODSSixty-seven patients with de novo or non-stented restenostic coronary lesions were chosen to receive the Firebird 2 stent as the final treatment (Firebird 2 group). Another 49 consecutive patients were implanted with bare cobalt alloyed stents (Driver, Medtronic) within the previous six months and served as historical controls (control group). Baseline clinical characteristics, angiographic features, procedural results, 30-day, 6-month and 12-month clinical follow-up regarding the occurrence of major adverse cardiac events (MACE), as well as the primary endpoint of late lumen loss at 6-month angiographic follow-up were compared between the two groups.

RESULTSThe demographic characteristics were similar between the two groups despite more patients in the Firebird 2 group who underwent previous percutaneous coronary intervention (22.4% vs 8.2%, P = 0.0418) and who had diabetes mellitus (29.9% vs 12.2%, P = 0.0253). In the Firebird 2 group, the mean diameter of the reference vessel was smaller ((2.79 +/- 0.46) mm vs (2.98 +/- 0.49) mm, P = 0.0175) and more stents were implanted for each lesion (1.28 +/- 0.52 vs 1.10 +/- 0.30, P = 0.0060). Other angiographic, procedural results and the device success rate were similar between the two groups. The MACE rate at 30-day and 3-month was the same, but significantly fewer MACE occurred in the Firebird 2 group at 6- and 12-month follow-up (1.5% vs 12.2% at 6 month, P = 0.0168; 1.5% vs 26.5% at 12 month, P < 0.0001). The primary endpoint of late lumen loss at 6-month angiographic follow-up was significantly reduced in the Firebird 2 group (in-stent: (0.05 +/- 0.09) mm vs (0.98 +/- 0.61) mm; in-segment: (0.05 +/- 0.18) mm vs (0.72 +/- 0.59) mm; P < 0.0001) than the control group. One patient in the Firebird 2 group had in-segment restenosis (1.3%) while the rate in the control group (38.1%) was significantly higher, P < 0.0001. Intravascular ultrasound examination was performed in 70.1% of patients in the Firebird 2 group and revealed that the percentage of volumetric obstruction was (1.26 +/- 1.05)%. No stent thrombosis was observed in either group at 12-month follow-up.

CONCLUSIONThe Firebird 2 sirolimus-eluting cobalt alloyed stent is safe and feasible in treating patients with coronary artery disease.

BACKGROUNDDrug-eluting stents (DES) have been shown to significantly reduce clinical events and angiographic restenosis in the treatment of coronary artery disease (CAD). This study was conducted to assess the long-term efficacy and safety of the polymer-based sirolimus-eluting cobalt-chromium Firebird 2 stents in the treatment of patients with CAD.

METHODSThis first-in-man study using the Firebird 2 stent is a prospective, historically-controlled multicenter clinical study, which enrolled 67 patients with CAD who were treated with the sirolimus-eluting cobalt-chromium stent (Firebird 2, Microport Shanghai, Firebird 2 group), compared to another 49 patients treated with a bare cobalt alloy stent (Driver, Medtronic, control group). Continued 2-year clinical follow-up was performed after getting the initial 6-month angiographic and 1-year clinical follow-up. The incidence of major adverse cardiac events (MACE) including cardiac death, reinfarction and target lesion revascularization (TLR) and stent thrombosis were compared between the two groups.

RESULTSAll patients in the Firebird 2 group (100.0%) and 48 patients in the control group (98.0%) completed the 2-year clinical follow-up. At the 1-year follow-up the use of the Firebird 2 stent was highly effective, resulting in a significant 94% decrease of TLR (26.5% in the control group and 1.5% in the Firebird 2 group, P<0.0001). A significant difference in TLR was maintained at 2-year follow-up, Firebird 2 group 1.5% and the control group 31.3% (P<0.0001). Between 1- and 2-year post-stenting, no more TLR occurred in the Firebird 2 group compared with two cases in the control group (P>0.05). There was a 1.5% incidence of MACE at 1- and 2-year follow-up in the Firebird 2 group, compared with 26.5% and 33.3% in the control group, respectively (all P<0.0001). The cumulative 1- and 2-year MACE free survival rates were 98.5% in the Firebird 2 group vs 73.5% and 66.7% in the control group (log rank P<0.0001). No case of stent thrombosis occurred during 2-year follow-up in the Firebird 2 group, compared with one case that suffered a definite stent thrombosis in the control group at 19-month post-stenting: this patient presented with unstable angina pectoris and was treated by balloon angioplasty.

CONCLUSIONSCompared with the bare cobalt alloy stent, the Firebird 2 sirolimus-eluting cobalt-chromium stent is safe and effective in treating patients with CAD. The use of this stent was associated with a sustained clinical benefit and significantly lower rate of TLR and MACE up to 2 years post-stenting.
