This paper mainly discussed the present situation of the pension mode transformation from traditional family pension to social pension. The existing ethical issues in pension institution include: old filial piety thought deeply rooted;institutional care services cannot be carried out caused by unfair distribution balance; humanistic thought of human ethical care implementation does not do well; some agencies have occasional bad behavior. Therefore, this paper proposed some advices based bioethical perspective:for old people and their children, advo-cate the new filial piety;pension institutions not only improving the quality of the hardware but also should strength-en humanistic ethics concern;establish and perfect the laws and regulations, combining the rule of law with moral and ethical;the relevant government departments should insist on and strengthen the principle of fair justice.

In recent years , with the development of medical health and the progress of economy , the citizens'demands for daily health are improved continually , and health services need to be rapid development .However , in the principle of medical ethics and humanism humanistic care of patients , it is easy to ignore the other two key as-pects -the medical staff and patients with the family .This paper analyzed the emotion and psychology of patients'families and medical staff in caring for the patients and corresponding solutions , so that the three can effective communication to build a harmonious doctor -patient relationship , and then promote patient recovery and be advan-tageous to the long-term development of the reform of health services .

Objective To explore the clinical application of GlideScope video laryngoscope combined with fiberoptic bronchoscope for double-lumen endobronchial tube intubation in patients with difficult glottis exposure.Methods Forty patients undergoing scheduled for thoracic surgery (24 males,1 6 females,aged 24-78 years,falling into ASA Ⅰ or Ⅱ,Mallampati classification Ⅲ or Ⅳ, were randomly divided into two groups (n=20 each):GlideScope video laryngoscope combined with fiberoptic bronchoscope group (group GF)and Macintosh laryngoscope group (group M).In group GF,GlideScope video laryngoscopy combined with fiberoptic bronchoscope was used to guide the double-lumen tube bronchial intubation and then bronchoscope was used to check the placement of the tube.In group M,the double-lumen endobronchial tube was intubated with conventional macintosh laryngoscope,and then the placement of the tube was checked by bronchoscope.The results of the Cormack and Lehane grade measuring the degree of glottic opening during laryngoscopy,the intuba-tion time consumed,one-time intubation success rate,patients manoeuvre needed to aid tracheal intu-bation and endotracheal intubation related complications within 48 hours after operation were recorded and compared between the two groups.Results Compared with group M,the Cormack and Lehane grade was significantly better (P < 0.01 ), intubation time consumed was significantly shorter [(104.3±1 1.1)s vs.(138.6 ± 33.0)s](P < 0.01 ),one-time intubation success rate was higher (90% vs.55%)(P <0.05 ),fewer patients needed manoeuvre to aid tracheal intubation (20% vs. 90%)(P < 0.01 )and postoperative complications of hoarseness and pharyngalgia within 48 hours were significantly fewer (5% vs.35%,25% vs.75%)in group GF(P <0.05 ).Conclusion Com-pared with conventional method, GlideScope video laryngoscope combined with fiberoptic bronchoscope used to guide double-lumen endobronchial tube intubation in patients with difficult glottis exposure may improve the success rate of intubation,reduce the stress response of intubation and postoperative complications of hoarseness and pharyngalgia.

This study was aimed to observe the changes of dendritic spine density in different regions of brain among spleen-yindeficiency dementia (SYDD) model rats, in order to investigate the effects ofZi-Bu Pi-Yin Recipe (ZBPYR) on dendritic spines. Spleen-yindeficiency (SYD) rats were modeled by classical method. And incubatedβ-Amyloid 1-40 (Aβ1-40) was injected into the hippocampus of each rat to make SYDD model, which received the administration of ZBPYR. Golgi staining was used to stain dendritic spine in different regions of brain in rat model for the observation of the amount and shape. The results showed that dendritic spine density in different regions of hippocampus and cortex in SYDD group was reduced than that of the SYD group. Compared with the dementia group and the SYDD group, the dendritic spine density in different regions of hippocampus and cortex of the SYDD + ZBPYR group was increased. Compared with the blank control group, the dendritic spine density in different regions of hippocampus and cortex in rats from the dementia group was reduced. It was concluded that there were different degrees of reducing in the dendritic spine density of different brain regions in SYDD group. ZBPYR improved the learning and memory impairment, which might be related to the maintenance of dendritic spine density in different brain regions.

Objective To explore the prophylactic effect of methylprednisolone combined with granisetron on postoperative nausea and vomiting.Methods Two hundred patients scheduled for lumpectomy of breast were randomly divided into four groups with 50 cases each.The patients in group M1 received a pre-anesthesia intravenous doses of methylprednisolone 25 mg,the patients in group M2 were injected methylpredsisolone 25 mg repeatedly four hours later,in group D received a pre-anesthesia doses of dexamethasone 5 mg,in group N normal saline 2 ml.All the four groups of patients received granisetron 3 mg intravenously at the end of surgery.The incidence of nausea and vomiting in the 24 hours were observed.Results The PONV incidences of group M1,M2,D,N were 36%,18%,38% and 58%.Both group M1,M2 and D significantly decreased the total inci-dence of PONV (P <0.05)in the 24 h.The incidence of PONV was significantly lower in group M2, compared with group M1 and group D respectively (P <0.05).Conclusion Methylprednisolone-gran-isetron combination is as equally effective as dexamethasone-granisetron combination for preventing PONV in lumpectomy,but repeated methylprednisolone after 4 h is more effective than dexametha-sone and single-used methylprednisolone.

Objective:To detect serum level of complement factor B (CFB), and to explore its correlations with clinical parameters and prognosis in children with primary IgA nephropathy (IgAN).Methods:A total of 204 children with primary IgAN confirmed by kidney biopsy in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from December 2014 to April 2017 were included in IgAN group.During the same period, 84 healthy children were included in healthy control group.Their mean age was (11.0±3.5) years and (10.9±3.2) years, respectively.Patients in IgAN group were divided into low CFB group (102 cases) and high CFB group (102 cases) according to the medium serum level of CFB measured by enzyme-linked immunosorbent assay. Spearman′ s coefficient was employed to analyze correlation amongst various parameters.Multivariable-adjusted Cox proportional ha-zards models were used to evaluate the relationship between serum CFB level and prognosis in children with IgAN. Results:Serum CFB levels were significantly higher in IgAN group than that in healthy control group [290.9 (186.2-453.9) mg/L vs.218.9 (155.0-321.3) mg/L, Z=-3.372, P=0.001]. Serum levels of CFB were negatively correlated with serum albumin ( r=-0.388, P<0.001) and estimated glomerular filtration rate ( r=-0.416, P<0.001), but positively correlated with serum creatinine ( r=0.305, P<0.001) and 24 h urinary protein ( r=0.456, P<0.001) in IgAN group.The incidences of crescents (C1-2) (70.6% vs.29.4%, χ2=34.588, P<0.001) and C 3 deposition (+ + -+ + + ) (63.7% vs.44.1%, χ2=7.892, P=0.005) were significantly higher in high CFB group than those in low CFB group. Kaplan- Meier analysis showed that high CFB levels predicted worse renal outcome in pediatric IgAN patients ( χ2=17.509, P<0.001). Multivariate Cox regression analysis showed that the high CFB level was the independent risk factor for the poor renal outcome ( HR=2.517, 95% CI: 1.284-4.932, P=0.007). Conclusions:High serum levels of CFB are associated with decreased renal function, increased urinary protein excretion, crescentic formation and poor renal outcome in pediatric IgAN patients.

Objective:To investigate changes in serum C3d and C5b-9 levels in elderly patients with idiopathic membranous nephropathy(IMN)and their correlations with prognosis.Methods:Two hundred thirty-one elderly patients with IMN and 96 non-elderly patients with IMN confirmed by kidney biopsy at the First Affiliated Hospital of Zhengzhou University from January 2015 to May 2017 were enrolled.During the same period, 118 healthy individuals receiving health checkups were included as controls.Patients were divided into the low C3d group( n=112)and the high C3d group( n=113)according to the median level of serum C3d.Serum C3d and C5b-9 levels were measured by enzyme-linked immunosorbent assays. Results:Serum C3d and C5b-9 levels in elderly IMN patients were 0.23(0.15, 0.45)mg/L and 0.28(0.20, 1.23)mg/L, respectively, which were higher than those in healthy controls[0.18(0.13, 0.22)mg/L, 0.22(0.16, 0.26)mg/L, respectively]( Z=-4.261 and -6.213, P<0.001). Serum C3d levels in elderly and non-elderly IMN patients were correlated negatively with the estimated glomerular filtration rate( r=-0.155 and -0.426, P=0.019 and 0.000), but positively with serum creatinine, anti-phospholipase A2 receptor(PLA2R)antibody levels and 24 h urinary protein( r=0.184, 0.326, 0.407, 0.321 and 0.145, P=0.005, 0.001, 0.000, 0.001 and 0.027). Kaplan-Meier survival analysis showed that the cumulative renal survival rate in elderly IMN patients was lower in the high C3d group than in the low C3d group(47.8% vs.70.8%, Log Rank χ2=7.399, P=0.007). Multivariate Cox regression analysis showed that high C3d levels were an independent risk factor for poor renal outcomes in elderly IMN patients( HR=2.288, 95% CI: 1.082-4.839, P=0.030). Conclusions:High serum C3d levels are associated with increases in urinary protein excretion and anti-PLA2R antibody levels, renal function decline, and poor renal outcomes in elderly IMN patients.

OBJECTIVE: To develop a genotyping method for the Junior blood type and report on a rare blood type with Jr(a-). METHODS: Healthy O-type RhD+ volunteer donors of the Shenzhen Blood Center from January to May 2021 (n = 1 568) and a pedigree with difficult cross-matching (n = 3) were selected as the study subjects. Serological methods were used for proband's blood type identification, unexpected antibody identification, and antibody titer determination. Polymerase chain reaction-sequence specific primer (PCR-SSP) method was used for typing the proband's RhD gene. ABCG2 gene coding region sequencing and a PCR-SSP genotyping method were established for determining the genotypes of the proband and his family members and screening of Jra antigen-negative rare blood type among the 1 568 blood donors. RESULTS: The proband's ABO and RhD blood types were respectively determined as B and partial D (RHDDVI.3/RHD01N.01), Junior blood type Jra antigen was negative, and plasma had contained anti-D and anti-Jra. Sequencing of the ABCG2 gene revealed that the proband's genotype was ABGG201N.01/ABGG201N.01 [homozygous c.376C>T (p.Gln126X) variants], which is the most common Jr(a-) blood type allele in the Asian population. Screening of the voluntary blood donors has detected no Jr(a-) rare blood type. Statistical analysis of the heterozygotes suggested that the allelic frequency for ABCG2*01N.01 (c.376T) was 0.45%, and the frequency of Jr(a-) rare blood type with this molecular background was about 0.2‰. CONCLUSION A very rare case of partial DVI.3 type and Jr(a-) rare blood type has been identified. And a method for identifying the Junior blood type through sequencing the coding regions of the ABCG2 gene and PCR-SSP has been established.

Objective    To compare the subaxillary small incision thoracotomy (SSIT) with video-assisted thoracic surgery (VATS) for patients with lung cancer. Methods    Retrospective analysis of 142 patients with lung cancer in Department of Thoracic Surgery, The First People's Hospital of Neijiang from January 2014 to April 2016 was conducted. There were 86 males and 56 females, aged 40-77 years. Patients were divided into a VATS group (n=72) and a SSIT group (n=70). The following postoperative data were evaluated: operation time, number of dissected lymph nodes, intraoperative bleeding, postoperative chest drainage volume, drainage duration, postoperative ambulation time, average hospital stay, postoperative complications, hospitalization cost, early postoperative incision pain (visual analogue scale, VAS) and other indicators. Results    There were no statistically significant differences between the two groups in the operation time (120.8±20.4 min vs. 126.2±21.6 min, P=0.124), the dissected lymph node (11.1±2.0 vs. 11.4±1.9, P=0.333) and the postoperative complications rate (13.9% vs. 15.7%, P=0.759). Laparoscopic intraoperative bleeding and postoperative drainage volume were significantly less in the VATS group than those in the SSIT group (123.2±26.9 ml vs. 156.4±24.0 ml, P<0.001; 227.0±75.5 ml vs. 334.3±89.1 ml, P<0.001). Postoperative drainage duration, postoperative ambulation time and hospital stay were shorter in the VATS group than those in the SSIT group (2.5±0.5 d vs. 3.1±0.6 d, 1.5±0.5 d vs. 2.2±0.6 d, 6.5±0.5 d vs. 7.4±0.6 d, all P<0.001). The average hospitalization cost of the VATS group was significantly higher than that of the SSIT group (42 338.9±8 855.7 yuan vs. 32 043.7±7 178.1 yuan, P<0.001). There was no significant difference in the operation cost and anesthesia cost between the two groups (P>0.05). The early postoperative pain of laparoscopic group was less, but the difference was not statistically significant (P>0.05). Conclusion    The hospitalization cost of the SSIT is lower than that of thoracic surgery, which may be beneficial to the appilication in primary hospitals.
