The clinical efficacies were compared after a treatment course.Result The total effective rate was 93.3% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Peng’s eye acupuncture is an effective method in treating headache.

BACKGROUND:Polyvinyl alcohol (PVA) hydrogel with similar porous structure and mechanical properties to the natural cartilage is very suitable for the repair of articular cartilage. However, the pure PVA hydrogel after lyophilization wil be accompanied by the shrinkage of the polymer network and the col apse of the pores, leading to the inhomogeneous performance of the material even in the state of re-swel ing. Addition of the active polymer wil increase the cel adhesion ability of PVA hydrogel. OBJECTIVE:To construct PVA/lota-carrageenan (l-CA) composite materials with different mass fractions of l-CA and evaluate the biocompatibility with vascular endothelial cel s. METHODS:PVA/l-CA composite films with different contents of l-CA were fabricated and then co-cultured with vascular endothelial cel s. Attachment, proliferation and morphological changes of vascular endothelial cel s on the composite were observed by scanning electron microscope and MTT assay to evaluate its biocompatibility. PVA/l-CA three-dimensional scaffold with different contents of l-CA were constructed, and hemolysis experiment was conducted according to the biological evaluation standards of medical devices, and the porosity and pore size were observed using scanning electron microscope. RESULTS AND CONCLUSION:In vitro experimental results showed that the addition of l-CA could significantly increase the biological activity of PVA hydrogel, and promote the cel attachment and proliferation on the scaffold. The hemolysis rate of each experimental group was less than 5%(the accepted safety standard), suggesting that the composite materials were in accordance with the standard of medical devices for hemolysis experiment. These findings indicate that the composite scaffolds with 20%-30%l-CA possess the pore size suitable for cel growth and proliferation and the porosity beneficial for transportation of nutrients and metabolites, which can serve as an excel ent scaffold for tissue engineering.

Dermatomyofibroma is a benign and rare proliferation of myofibroblasts and fibroblasts of the skin.Dermatomyofibroma commonly locates at the shoulder and neck of young adults and adolescents.Other frequently affected anatomic sites are upper arms,thigh,chest wall,back,axillary region and abdomen.Herein,we reported a case of dermatomyofibroma occurred in the nasion.The asymptomatic firm nodule and histopathological features were consistent with dermatomyofibroma.Immunohistochemically,the tumor cells expressed vimentin,HHF35 and α-smooth muscle actin (α-SMA).The patient was followed up for 2 years after excision of the tumors and recurrences were not observed.

Objective:To evaluate the optimized effect of erector spinae plane block (ESPB) combined with general anesthesia when used for the patients undergoing laparoscopic pancreaticoduodenectomy.Methods:Sixty-eight American Society of Anesthesiologists physical status Ⅱ orⅢ patients of both sexes, aged 18-64 yr, with body mass index of 18-24 kg/m 2, scheduled for elective laparoscopic pancreaticoduodenectomy, were divided into general anesthesia group (group G, n=34) and ESPB combined with general anesthesia group (group EG, n=34) using a random number table method.In group E, ultrasound-guided ESPB was performed before induction with general anesthesia, and 0.375% ropivacaine 20 ml was injected into both sides.Total intravenous anesthesia was applied in both groups.Patient-controlled intravenous analgesia (PCIA) with sufentanil 1.5 g/kg in 100 ml of normal saline was performed after surgery.The PCIA pump was set up to deliver a 2 ml bolus dose with a 5-min lockout interval and background infusion at 3 ml/h.Analgesia was performed until 24 h after operation, and the visual analogue scale score at rest was maintained at ≤4.Sufentanil 0.1 g/kg was intravenously injected as rescue analgesic when visual analogue scale score >4.The extubation time and occurrence of intraoperative cardiovascular events were recorded.The amount of sufentanil used during operation and within 24 h after operation was recorded.The time to first pressing the analgesia pump after operation and effective pressing times of PCA within 24 h after operation were recorded.Time to first flatus, first ambulation time and length of postoperative hospital stay were recorded.The development of postoperative adverse reactions such as nausea and vomiting, irritability and respiratory depression within 24 h after operation was recorded. Results:Compared with group G, the incidence of intraoperative hypertension and tachycardia was significantly decreased, the extubation time was shortened, the consumption of sufentanil during operation and within 24 h after operation was reduced, the time to first pressing the analgesia pump was prolonged, the effective pressing times of PCA within 24 h after operation were reduced, time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, and the incidence of nausea and vomiting, irritability and respiratory depression within 24 h after operation was decreased in group EG ( P<0.05). Conclusion:The combination of ESPB and general anesthesia is helpful in achieving an anesthesia mode of lower opioid consumption and more helpful for inhibition of postoperative pain responses and for early postoperative recovery than general anesthesia alone when used for the patients undergoing laparoscopic pancreaticoduodenectomy.

Objective:To get norovirus (NoV) GII.6 P protein through prokaryotic expression and prepare the polyclonal antibody.Methods:NoV GII.6 P region gene was amplified and cloned into prokaryotic expression vector pET28a, and the recombinant plasmid was transformed into E. coli BL21 (DE3) competent cell. The recombinant protein GII.6 P was expressed by induced Isopropyl β-D-Thiogalactoside (IPTG) and then purified with Ni-NTA Affinity Column. The binding ability of recombinant GII.6 P was determined by oligosaccharide binding assay and the polyclonal antibody serum was prepared by immunizing BALB/c mice. The titer of GII.6 P polyclonal antibody was determined by ELISA, and the specificity of the antibody was detected by western blot (WB). The effectiveness of GII.6 P polyclonal antibody was assessed. Results:The recombinant GII.6P-pET28a plasmid was constructed successfully and the recombinant GII.6 P protein was expressed with relative molecular mass of 40 ×10 3. The purity of GII.6P protein was more than 90% after purification. The oligosaccharide binding showed that the GII.6 P protein binds to B, le b and H2, but does not bind to A, H1, and le a type; the titer of GII.6 P polyclonal antibody was 1∶160 000. WB indicated that the antibody had high specificity and the cross experiments did not show affinity to GII.4. Conclusions:The GII.6P protein has been expressed successfully and the GII.6 P polyclonal antibody with high titer was prepared, which provides an effective tool for detection and vaccine development for NoV GII.6.

In recent years,challenges persist in the grassroots Party building in the university-affiliated hospitals though increased efforts have been intensified.These challenges include a lack of alignment between Party building and the hospital's central tasks,an absence of distinctive Party building brands,an insufficiently prominent role of Party organizations in hospital development,and inadequate leveraging of the Party construction for promoting medical services and cultivating medical talents.Starting from an exploration of the connotation and significance of constructing framework of"One Integration and Two Highs"in university-affiliated hospitals,this paper conducts an in-depth analysis of the existing problems and their causes within this frame-work.From a holistic perspective,the paper proposes a new path for establishing the"One Integration and Two Highs"frame-work in university-affiliated hospitals,centered around"Seven Integrations":concept integration,organization integration,strength integration,vehicle integration,culture integration,innovation integration,and assessment integration.

Objective:To explore the molecular pathogenesis of a family with hereditary factor Ⅴ (FⅤ) deficiency.Methods:All the exons, flanking sequences, 5′ and 3′ untranslated regions of the F5 of the proband, and the corresponding mutation sites of the family members were analyzed via direct DNA sequencing. The CAT measurement was used to detect the amount of thrombin produced. The ClustalX software was used to analyze the conservation of mutation sites. The online bioinformatics software, Mutation Taster, PolyPhen-2, PROVEAN, LRT, and SIFT were applied to predict the effects of mutation sites on protein function. The Swiss-PdbViewer software was used to analyze the changes in the protein model and intermolecular force before and after amino acid variation.Results:The proband had a heterozygous missense mutation c.1258G>T (p.Gly392Cys) in exon 8 of the F5, and a heterozygous deletion mutation c.4797delG (p.Glu1572Lys fsX19) in exon 14, which results in a frameshift and produces a truncated protein. Her grandfather and father had p.Gly392Cys heterozygous variation, whereas her maternal grandmother, mother, little aunt, and cousin all had p.Glu1572LysfsX19 heterozygous variation. The ratio of proband's thrombin generation delay to peak time was significantly increased. Conservation analysis results showed that p.Gly392 was located in a conserved region among the 10 homologous species. Five online bioinformatics software predicted that p.Gly392Cys was pathogenic, and Mutation Taster also predicted p.Glu1572Lys fsX19 as a pathogenic variant. Protein model analysis showed that the replacement of Gly392 by Cys392 can lead to the extension of the original hydrogen bond and the formation of a new steric hindrance, which affected the stability of the protein structure.Conclusion:The c.1258G>T heterozygous missense mutation in exon 8 and the c.4797delG heterozygous deletion mutation in exon 14 of the F5 may be responsible for the decrease of FⅤ levels in this family.

Objective:To analyze the salary level, change trend and salary satisfaction of nurses in tertiary public hospitals in China.Methods:The data was derived from three round third-party evaluation of the China Healthcare Improvement Initiative at 136 tertiary public hospitals from December 2017 to January 2018, March 2019 and January to March 2021. The self-reported salary, expected salary and salary satisfaction rate of nurses were analyzed.Results:The sample sizes of the three evaluations were 27 575, 27 568 and 25 197, representing the salary situation in 2017, 2018 and 2020 respectively. In 2017, 2018 and 2020, the actual average annual salary of nurses was 81 600 yuan, 100 000 yuan and 110 000 yuan respectively, the expected average annual salary was 140 000 yuan, 160 000 yuan and 160 000 yuan respectively, and the ratio of expected salary to actual salary was 1.72, 1.60 and 1.45 respectively. In 2017, 2018 and 2020, the proportion of nurses satisfied with their current income was 34.0%, 33.7% and 43.6% respectively. In 2020, nurses in the eastern region, other specialized hospitals, senior professional titles and graduate degrees had highest annual salary.Conclusions:The salary level and satisfaction rate of nurses in tertiary public hospitals in China show a slow growth trend, and the gap between actual salary and expected salary is gradually narrowing.

OBJECTIVETo explore an optimum method on postoperative recovery of general-anesthesia gynecological laparoscopic surgery.

METHODSOne hundred and twenty cases of gynecological laparoscopic surgery were randomly divided into three groups, 40 cases in each one. The sensitive points of bilateral Shenmen (TF4), Zigong (TF2), Wei (CO4), Dachang (CO7) and so on were selected in all three groups one night before the surgery. The sticking with magnetic beads was applied in the group A. The magnetic beads were in-pair stuck at front-back corresponding location of both ears in the group B. The same-appearance plaster was put at the corresponding acupoints in the group C. The intubation anesthesia was applied in all three groups and postoperative recovery of gynecological laparoscopic surgery was observed.

RESULTSThe postoperative visual analogue scale (VAS) was (1.77 +/- 1.65) in the group A and (1.80 +/- 1.96) in the group B, which was both lower than (2.62 +/- 1.46) in the group C (both P < 0.01). The occurrence rate of nausea and vomiting was 25.0% (9/36) in the group A and 20.0% (8/40) in the group B, which was both lower than 50.0% (19/38) in the group C (both P < 0.01). The recovery of borborygmus on postoperative 1st and 3rd day in the group A and B was faster than that in the group C (both P < 0.05), while time of fart and defecation in the group A and B was earlier than that in the group C (both P < 0.05). The score of state-trait anxiety inventory in the group A and B was lower than that in the group C (both P < 0.05), but the differences of each item between the group A and B were not obvious (both P > 0.05).

CONCLUSIONThe auricular point sticking could support analgesia of general-anesthesia gynecological laparoscopic surgery, which could relieve anxiety mood, reduce occurrence of nausea and vomiting and improve function of stomach and intestine to benefit postoperative recovery. However, the effect of in-pair sticking of auricular point with magnetic beads at front-back acupoints was not obviously strengthened.
