Objective:To analyze the relationship between the optimal surgical margin value and clinical prognosis of transoral robotic surgery（TORS） in treating human papillomavirus（HPV） -positive oropharyngeal squamous cell carcinoma. Methods:A single-center, prospective, observational cohort study was conducted, enrolling patients with early and moderated stage（≤T3 stage） oropharyngeal carcinoma undergoing TORS between July 2020 and April 2024. The proposed optimal surgical margin cutoff value for TORS was set as 2 mm. The primary objectives were to evaluate the optimal clear margin for TORS and its association with overall survival（OS） and progression-free survival（PFS）. Logistic regression was used to analyze correlations between surgical margins and clinical variables, while Cox regression models assessed the impact of surgical margins on OS and PFS. Results:A total of 90 patients（60 males, 66.7%） were included, all had squamous cell carcinoma, with a mean age of 58.0±9.0 years（range: 39-84 years） old. The 1, 2 and 3-year OS rates were 92.3%, 89.9% and 85.0%, respectively, while the 1, 2 and 3-year PFS rates were all 90.1%. For surgical margins ≤2 mm, the 1, 2 and 3-year OS rates were 80.8%, 69.3% and 69.3%, respectively, and PFS rates were 77.9% across three time points. For surgical margins>2 mm, the 1, 2 and 3-year OS rates were 96.5%, 96.5% and 90.6%, respectively, with PFS rates of 94.6%. Logistic regression showed no correlation between surgical margins and tumor type, T/N stage, smoking, alcohol use, or gender（P>0.05）. Cox analysis identified surgical margins>2 mm as a significant factor improving PFS（HR=0.14, 95%CI 0.02-0.90, P=0.038）. Conclusion:This systematic analysis suggests setting a 2 mm and longer as clear surgical margin for TORS. Margins>2 mm are associated with superior postoperative PFS rate and prolonged PFS time in HPV-positive oropharyngeal carcinoma patients.

Objective:To investigate the professional identity status of nursing students in higher vocational colleges in Shanghai, China, and to analyze the influencing factors.Methods:By cluster sampling, we selected 308 nursing students of grade 2019 from a higher vocational college in Shanghai for a survey with the General Information Questionnaire, Professional Identity Questionnaire for Nurse Students (PIQNS), Stanford Presenteeism Scale-6 (SPS-6), Wong and Law Emotional Intelligence Scale (WLEIS), Workplace Social Capital (WSC), and Nurse Psychological Capital Questionnaire (PCQ). SPSS 22.0 was used for descriptive analysis, the independent samples t-test, one-way analysis of variance, Pearson correlation analysis, and multiple linear regression analysis. Results:The total PIQNS score of the students was (64.93±12.83), the total SPS-6 score was (15.91±4.40), the total WLEIS score was (80.57±15.52), the total WSC score was (32.38±6.33), and the total PCQ score was (95.47±18.63). The PIQNS score was negatively correlated with the SPS-6 score ( r=-0.282, P<0.01), positively correlated with the WLEIS score ( r=0.712, P<0.01), positively correlated with the WSC score ( r=0.659, P<0.01), and positively correlated with the PCQ score ( r=0.681, P<0.01). The multiple linear regression analysis showed that personal interest, emotional intelligence, and psychological capital significantly affected the professional identity of nursing students, entering the regression equation for professional identity. Conclusions:The professional identity of higher vocational nursing students in Shanghai is at a medium level, and personal interest, emotional intelligence, and psychological capital are the main factors influencing professional identity.

A male child aged two years and six months was admitted to the Affiliated Women and Children′s Hospital of Qingdao University in June 2023 due to wide eye distance, stubby fingers, koilosternia, cryptorchidism, and short tongue frenum. After clinical data collection, whole exome sequencing (WES) was conducted and bio-informatics analysis was performed to search for possible mutation sites on the patient. Family lineage verifications were conducted through Sanger sequencing. WES results showed that the patient carried c.2432dupT frameshift hemizygote variation of the FGD1 gene on the X chromosome (Xq11.22). Sanger sequencing confirmed that the mother was a carrier of the c.2432dupT heterozygous variant but not the father. According to the sequence interpretation guidelines of the American College of Medical Genetics and Genomics (ACMG), this variant is pathogenic (ACMG: PVS+2PP). The patient was diagnosed with Aarskog-Scott syndrome(ASS), which is a rare X-linked disorder characterized by facial, skeletal and genital anomalies. This case study has enriched the variant spectrum of the FGD1 gene and provided guidance for clinical screening and diagnosis of ASS.

Objective To investigate the relationship between serum L-carnitine and its related metabolites[trimethylamine(TMA)and trimethylamine N-oxide(TMAO)]levels and gestational diabetes mellitus(GDM)in the second trimester of pregnant women in Shanghai.Methods A case-control study was conducted in 280 pregnant women between 18 and 23 weeks of gestation from January 2018 to January 2021.Among them,134 cases of GDM were the case group(GDM),and 146 cases with normal blood glucose(BG)were the control group(Con).Serum L-carnitine,TMA and TMAO levels were quantified by ultra high performance liquid chromatography-mass spectrometry.Logistic regression analysis,stratified analysis and linear regression were used to explore the relationship between L-carnitine,TMA and TMAO levels and GDM and glucolipid metabolism.Results Serum L-carnitinelevelwas significantly lower in GDM group than that in Con group(P<0.01).After adjusting for confounders,logistic regression showed a 70%reduction in the risk of GDM in the group with highest tertile of L-carnitine compared with the group with lowest tertile(OR 0.30,95%CI 0.15～0.63).The risk of GDM decreased by 14%for each 1 μmol/L increase in serum L-carnitine(OR 0.86,95%CI 0.80～0.93).Serum L-carnitine was negatively correlated with 1 hPG(r=-0.21,P<0.01)and 2 hPG(r=-0.15,P<0.05),respectively,TMA was negatively correlated with 2 hPG(r=-0.21,P<0.01).Conclusions Higher serum L-carnitine level may be negatively associated with GDM.Serum L-carnitine and TMA levels were negatively correlated with blood glucose levels.

The prevention and treatment of COVID-19 in China is now at a key stage. The tasks faced by the medical organs are fighting against the COVID-19 while providing the medical services orderly. As a Specialist medical institution nationwide, ophthalmic hospitals are resuming receiving patients and performing operations gradually, including precision interruption of the epidemic, prevention of the secondary virus transmission, and avoidance of nosocomial cross infection among health care providers are required. We explored a multifaceted management for the prevention and control of epidemic, with a special focus on the individual protection for patients and medical staffs. A preliminary positive effect can be observed as a result. The main measures taken cover two aspects. On the one hand, 2019-nCoV ribonucleic acid (RNA) detection and hematological indices inspection including C-reactive protein (CRP) and serum amyloid A (SAA) are listed as routine tests of preoperative screening for ocular surgical patients. These tests are required to be completed upon the admission to avoid the possibility of accepting any asymptomatic infected individual and to reduce the risk of nosocomial cross infection. On the other hand, the 2019-nCoV RNA detection is also provided to high-risk employees who visited affected area recently. This assists in obtaining guarantee in both safety and quality of medical services provided, but also helps in lessening the mental and spiritual stress for medical staffs. It is expected that these measures can contribute to the work of our peers of ophthalmology in the prevention and control of COVID-19 and to the safe environment where the medical services are provided, and provide a reference for other outbreak of virus-causing disease.

[Abstract] Objective: To investigate the effect of HMGB1 gene on the growth of human epithelial ovarian cancer xenografts in nude mice, and to lay a foundation for finding new targets for the treatment of ovarian cancer. Methods: Human epithelial ovarian cancer SKOV3 cells in logarithmic growth phase were selected to establish a human epithelial ovarian cancer xenograft model in nude mice. Nude mice with successful model establishment were randomly divided into control group and HMGB1-siRNA group. On the 7th, 9th, 11th, 14th, and 16th days after cell inoculation, the same amount of saline and HMGB1-siRNA were respectively injected into two groups of mice under the armpit.After 3 weeks, the nude mice were sacrificed by cervical dislocation, the tumor tissues were separated, and the volume of the tumor was measured. The apoptosis of transplanted tumor cells was detected by Tunnel staining. The expressions of HMGB1, STAT3 and p-STAT3 were detected by Western blotting. The expression of vascular endothelial growth factorA(VEGF-A) and microvascularization were detected by immunohistochemistry. Results: Compared with the control group, the growth of tumor volume slowed down in HMGB1 siRNA group, and on the 21st day, the tumor volume of HMGB1-siRNA group was significantly smaller than that of the control group (P<0.05). HMGB1-siRNA successfully knocked down the expression of HMGB1 mRNA in transplanted tumor tissue. The apoptosis rate of tissue cells in HMGB1-siRNA group was significantly increased ([34±8]% vs [6±2]%, P=0.04), and the expressions of HMGB1 and p-STAT3 were significantly reduced (P<0.05). The expression of VEGF-Aand the number of microvessels were significantly lower than those of the control group (both P<0.05). Conclusion: Knockdown of HMGB1 gene reduces the expression of VEGF-A and microvessel formation possibly by inhibiting the HMGB1/STAT3 signaling pathway, thereby promoting the apoptosis of tumor tissues and slowing the growth of xenografts.

Objective To approach the significance of changes of percutaneous-arterial blood carbon dioxide partial pressure difference [P(tc-a)CO2] in liquid resuscitation of patients with septic shock. Methods One hundred and sixty-eight patients with septic shock admitted and treated in the Department of Intensive Care Unit (ICU) of Quzhou People's Hospital from January 2015 to January 2018 were enrolled, and after early goal-directed therapy (EGDT) for 6 hours, according to central venous oxygen saturation (ScvO2) and lactate clearance (LC), they were divided into ScvO2 and LC achievement group (ScvO2 ≥ 0.7 and LC≥10%), ScvO2 achievement group (ScvO2 ≥ 0.7 and LC < 10%), LC achievement group (ScvO2 < 0.7 and LC≥10%), and un-achievement group (ScvO2 < 0.7 and LC < 10%). The mechanical ventilation time, ICU hospitalization time, 28-day mortality, P(tc-a)CO2 etc. were compared among the four groups; the receiver operating characteristic curve (ROC) was used to evaluate the predictive value of P(tc-a)CO2 for 28-day prognosis in patients with septic shock. Results The trends of mechanical ventilation time, ICU hospitalization time, and 28-day mortality were all ScvO2 and LC achievement group < LC achievement group < ScvO2 achievement group < un-achievement group [the mechanical ventilation times (days) were respectively 6.12±2.59, 8.43±3.24, 11.78±4.12, 13.03±4.75, ICU hospitalization times (days) were 10.31±2.32, 13.85±3.56, 16.41±3.83, 18.52±4.05, and 28-day mortality rates were 28.85% (15/52), 40.91% (18/44), 51.28% (20/39), 69.70% (23/33)] and the differences among the four groups were statistically significant (all P < 0.05). After 6 hours of EGDT, the heart rate (HR), lactate (Lac), and P(tc-a)CO2 were lower than those before fluid resuscitation, but the mean arterial pressure (MAP), central venous pressure (CVP), and ScvO2 were higher than those before fluid resuscitation among four groups. Except CVP, the differences of other indicators compared among the ScvO2 and LC achievement group, ScvO2 achievement group, LC achievement group and un-achievement group were statistically significant (all P < 0.05). After 6 hours of EGDT, HR, Lac, P(tc-a)CO2 in ScvO2 and LC achievement group, ScvO2 achievement group and LC achievement group were significantly lower than those in the un-achievement group [HR (bpm): 89.05±29.43, 98.82±30.21, 94.33±28.64 vs. 112.85±32.74, Lac (mmol/L): 2.97±1.95, 3.87±2.32, 2.69±1.52 vs. 4.17±2.44, P(tc-a)CO2 (mmHg, 1 mmHg = 0133 kPa): 7.18±4.61, 12.61±5.34, 9.71±4.11 vs. 16.56±10.19], MAP and ScvO2 were significantly higher than those of the un-achievement group [MAP (mmHg): 88.05±21.67, 77.33±18.56, 83.11±19.71 vs. 70.32±18.79, ScvO2: 0.76±0.14, 0.75±0.16, 0.67±0.14 vs. 0.63±0.18, all P < 0.05]. The P(tc-a)CO2 of 28 days survivors were significantly lower than that of the deaths among four groups (mmHg: 5.78±2.27 vs. 14.14±3.65, 7.07±2.81 vs. 15.06±4.11, 6.35±2.09 vs. 14.94±4.06, 7.93±3.81 vs. 18.34±4.63, all P < 0.05). When P(tc-a)CO2 > 7.24 mmHg predicted 28-day mortality in ScvO2 and LC achievement group, the sensitivity was 89.29%, specificity was 91.45%, and the area under ROC curve (AUC) was 0.86; when P(tc-a)CO2 > 9.46 mmHg predicted 28-day mortality in LC achievement group, the sensitivity was 88.72%, specificity was 85.83% and AUC was 0.91; when P(tc-a)CO2 >12.05 mmHg predicted 28-day mortality in ScvO2 achievement group, the sensitivity was 82.79%, specificity was 86.90% and AUC was 0.79; when P(tc-a)CO2 > 16.22 mmHg predicted 28-day mortality in un-achievement group, the sensitivity was 73.35%, specificity was 80.68% and AUC was 0.68. Conclusion P(tc-a)CO2 can be used as an indicator to evaluate fluid resuscitation effect and prognosis in patients with septic shock.

Objective To evaluate the effect of enteral immune nutrition on the occurrence of acute kidney injury(AKI) in sepsis patients. Methods A retrospective study was conducted, 80 patients with sepsis admitted and treated in the intensive care unit (ICU) of Quzhou People's Hospital from January 2015 to December 2016 were enrolled, and according to different treatment programs, they were divided into an immune nutrition group and a standard nutrition group, each group 40 cases. The two groups received an equal amount of calories and nitrogen in enteral nutrition (EN). After treatment, the changes of serum total protein (TP), albumin (Alb), prealbumin (PA), hemoglobin (Hb), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin (IL-6, IL-10), infection site, length of stay in ICU, mortality in ICU, AKI incidence, AKI staging, etc in the two groups were observed. Results ① After treatment, the nutritional indicators TP, Alb, PA, Hb levels were significantly increased, the serum inflammatory factors CRP, TNF-α, IL-6 were obviously decreased and IL-10 was markedly increased in the two groups compared with those before treatment (all P < 0.05), the changes in the immune nutrition group were more obvious than those in the standard nutrition group [TP (g/L): 60.84±5.90 vs. 58.32±6.11, Alb (g/L): 33.95±3.83 vs. 31.79±3.44, PA (g/L): 0.24±0.04 vs. 0.21±0.03, Hb (g/L): 117.47±16.15 vs. 112.50±15.71, CRP (mg/L): 53.04±23.76 vs. 82.33±37.09, TNF-α (ng/L): 20.29±17.74 vs. 29.63±18.43, IL-6 (ng/L): 50.74±28.55 vs. 80.32±31.67, IL-10 (ng/L): 41.09±24.65 vs. 40.86±24.73]; ② The length of stay in ICU (days: 10.54±4.33 vs. 14.80±5.19), ICU mortality [15.00% (6/40) vs. 32.50% (13/40)] and the incidence of AKI [22.50% (9/40) vs. 47.50% (19/40)] of immune nutrition group were significantly lower than those of standard nutrition group (all P < 0.05); There were 9 cases of AKI mainly at stage I andⅡ (8 cases) in the immune nutrition group, while in the standard nutrition group there were 19 cases with AKI mainly at stageⅢ (11 cases). Conclusion The enteral immune nutrition can effectively reduce the incidence of AKI in sepsis patients, and the mechanism may be related to the immune nutritional preparation can inhibit the expressions of pro-inflammatory factors such as TNF-α, IL-6, etc.

Objective To assess the effects of cognitive-behavioral group psychotherapy on depression,anxiety and medication adherence in elderly patients with coronary heart disease.Methods Eighty patients from two communities in Qinghai province were randomly divided into intervention group (n=40) and control group (n=40).In addition to regular care for both groups,patients in the intervention group also received eognitive-behavioral group psychotherapy.Depression,anxiety and medication adherence were measured with the Zung Self-Rating Depression Scale (SDS),the Zung Self-Rating Anxiety Scale (SAS) and the eight-item Morisky Medication Adherence Scale (MMAS-8),respectively,at baseline,immediately after intervention,at 3 months after intervention,and at 6 months after intervention.Results The repeated-measures ANOVA showed that improvement in depression,anxiety and medication adherence before and after intervention in the intervention group was greater than in the control group (F =22.805,48.058,128.058,all P＜0.05).Scores for depression and anxiety were lower and scores for medication adherence were higher (all P＜0.05) in the intervention group than in the control group at all the time points after intervention.Conclusions Cognitive-behavioral group psychotherapy can alleviate depression and anxiety,and improve medication adherence in elderly patients with coronary heart disease.

Objectives To explore the efficacy of CaNa2EDTA in the treatment of chronic moderate lead poisoning, so as to optimize the chelation therapy for lead poisoning in children. Methods The clinical data of 14 patients with chronic moderate lead poisoning treated with CaNa2EDTA for 3 consecutive courses of lead removal during September 2014 to December 2016 were analyzed retrospectively. Twenty-four hour urinary lead levels during hospitalization were analyzed. The changes of blood lead levels before treatment, 3 days, and 5 days after treatment were also analyzed. Results In the 14 children (4 males and 10 females) average age was 2.35±1.47 years. After treatment with CaNa2EDTA for 3 consecutive courses, the blood lead levels were decreased significantly in all the patients, and the blood lead levels at 3 days after treatment were 0.76, 0.77, 0.72 times those at 5 days after treatment respectively. The decrease of blood lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). The decrease of blood lead levels at 3 days after treatment was 0.65, 0.71, 0.70 times , those in 5 days' treatment respectively. The decrease of urine lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). Conclusions CaNa2EDTA has an obvious effect on removal of lead.The efficiency of lead removal in 3 days of treatment was higher than in 5 days of treatment. Thus, a course of treatment for 3 days may be an altenative for a course of 5 days.
