Objective To learn the medical experience of inpatients at public hospitals in Henan and the influencing factors.Methods Inpatient experience questionnaire (IPEQ) was customized for a random sampling of 500 inpatients at five tertiary public hospitals in Henan.Results Overall satisfaction of inpatients experience scored 8.48,of which the satisfaction for technical competence was the highest (4.19)and that for emotional support the lowest(3.31).The correlation analysis revealed that the doctors' technical competence score the highest correlation with the experiences (0.652).Conclusion Overall satisfaction of inpatients experience at public hospitals in Henan was found high in general,but humanistic care and service flow at the hospitals require further improvement.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.

Objective To explore the surgical treatment of spindle aneurysms in V4 segment of vertebral artery. Methods The clinical data, surgical methods and prognosis of 6 patients with V4 spindle aneurysms of vertebral artery admitted from 2011 to November 2018 in Sanbo Brain Hospital were retrospectively analyzed,Results There were 4 males and 2 females aged from 45 to 65 years. Aneurysm rupture and bleeding occurred in 3 cases. Far lateral approach was used in all patients. One case was clipped with window aneurysms, 2 cases were treated with occipital artery (OA)- posterior inferior cerebellar artery (PICA) bypass, and 3 cases were treated with vertebral artery occlusion. Postoperative patients were generally in good condition. Postoperative CT arteriography confirmed that the bypass vessels were unobstructed in 2 cases. All vertebral aneurysms were treated satisfactorily and PICA arteries were preserved. Tracheotomy was performed in 5 patients (1 case was incised before operation). Three patients were removed 3 months after operation. The Glasgow Prognosis Score (GOS) was 4 points. Long-term tracheotomy was performed in 1 case, and GOS score was 3 points. Two patients died 4 months and 3 years after operation. Conclusions Craniotomy is an important method for the treatment of spindle aneurysm of V4 segment of vertebral artery. Different surgical methods should be selected according to the size of the aneurysm, the relationship between the location of the aneurysm and PICA, and the compensation of the vertebral artery.

Chronic myeloid leukemia (CML) is a malignant tumor formed by clonal proliferation of bone marrow hematopoietic stem cells. With the improvement of disease awareness and the introduction of new drugs, more than 90% of CML patients can achieve long-term survival. However, a few patients still show drug resistance. This article reviews the mechanism of drug resistance in CML patients treated with tyrosine kinase inhibitor (TKI) and the characteristics of ABL kinase region mutation.

Objective: To evaluate the efficacy of indocyanine green SPY imaging in flap surgery. Methods: Between July 2016 and March 2017, forty-five flaps of thirty-five consecutive patients were retrospectively analyzed, among which forty-four were pedicled flaps and one was free flap, measuring from 2.0 cm×1.5 cm to 34.0 cm×17.0 cm. SPY imaging was performed twice for each flap, after the elevation of flap and after flap insertion respectively. The correlation of the flap perfusion detected by SPY and the prognosis of each flap were recorded and analyzed. Results: Twenty-nine flaps demonstrated good perfusion on SPY healed uneventfully. Sixteen flaps were demonstrated poor perfusion in the distal part of flap. Two flaps underwent surgical intervention intraoperatively and totally survived. Fourteen flaps were preserved conservatively and nine suffered partial- or full-thickness necrosis. None of the remaining five flaps sustained necrosis. Secondary healing was achieved through regular dressing change or operative debridement. The sensitivity, specificity and accuracy were 100%(9/9), 85.3%(29/34) and 88.4%(38/43) respectively. Conclusions Intraoperative indocyanine green SPY imaging is a useful adjuvant to evaluate flap perfusion and predict necrosis in plastic surgery, enhancing a surgeon’s clinical judgment of flap viability.

Objective:To investigate the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with positive TLS-ERG fusion gene.Methods:The clinical data of 9 AML patients with positive TLS-ERG fusion gene in the First Hospital of Jilin University from June 2013 to August 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:Among 9 patients with positive TLS-ERG fusion gene, there were 5 males and 4 females, with a median age of 16 years old (6-40 years old). Five patients received chemotherapy alone, 3 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT), and 1 patient did not receive systematic treatment. Among 8 patients with systematic treatment, 1 patient had complete remission after the first induction chemotherapy and 5 patients had complete remission after induction therapy. The median overall survival time of 5 patients with chemotherapy alone was 1.5 months (1-11 months), of which 3 patients did not respond to the first course of treatment and died of infection, and 2 patients died after relapse. The median overall survival time of 3 patients with allo-HSCT was 16 months (13-17 months), of which 2 patients died after relapse and 1 patient had sustained molecular complete remission by the end of follow-up.Conclusions:AML with positive TLS-ERG fusion gene has low incidence rate and poor induction efficacy. Hematopoietic stem cell transplantation may partially improve the survival prognosis of patients, but it cannot overcome the adverse effect of positive TLS-ERG fusion gene on prognosis.

Objective:To construct an aggregation induced emission (AIE) self-assembled probe based on glutathione (GSH) response covalent cyclization and evaluate it in vitro.Methods:The peptide sequence containing the 2-cyano-6-aminobenzothiazole-cysteine (CBT-Cys) condensation sequence was synthesized by the solid-phase peptide synthesis method. After coupling with an AIE molecule by click chemical reaction, an AIE self-assembled probe 1 based on GSH response covalent cyclization was constructed, and probe 2 lacking Cys structure was used as the control. The absorption and emission spectra of probes were tested and the specificity of probes to GSH was analyzed. The hydrodynamic diameter and structure of the probes after response were compared. The effects of different pH values, temperatures, probe concentrations, and GSH concentrations on fluorescence intensity were investigated. The toxicity of probes to tumor cells such as HeLa, HepG2 and MDA-MB-231 was evaluated.Results:After GSH response, the fluorescence of probe 1 was enhanced by about 6 times and that of probe 2 was enhanced by about 2 times; probe 1 was converted into a dimer with a hydrodynamic diameter of about 896.1 nm. Probe 2 lacked a cyclization motif and was converted into a monomer with a hydrodynamic diameter of about 427.4 nm. The fluorescence intensity of probe 1 was significantly higher than that of probe 2 at pH=7.0 and 37 ℃, and the toxicity of probes to tumor cells (HeLa, HepG2 and MDA-MB-231) was low.Conclusions:After the disulfide bond of probe 1 was reduced by GSH, the probe molecule lost the hydrophilic sequence, resulting in fluorescence turn-on (the first aggregation), and probe 1 immediately generates an AIE dimer (the second aggregation) because it contains a CBT-Cys cyclization sequence, which realizes the dual AIE effect compared with the single aggregation of probe 2, and significantly enhances the fluorescence emission. Probe 1 has better applicability in physiological environments, which provides an idea for in-situ generation of covalent cycling probes in vivo and is expected to be used in tumor imaging and treatment in the later stages.

Objective:To explore the etiology and treatment of craniopharyngioma with aneurysm.Methods:Seven cases of craniopharyngioma with aneurysm from March 2014 to October 2019 treated in Sanbo Brain Hospital, Capital Medical University were retrospectively analyzed. Among the 7 patients, there were 5 males and 2 females. There were 4 cases of recurrent craniopharyngiomas, 1 case of primary tumor and 2 cases of non-recurrence tumor. Three patients with blood blister-like aneurysms were treated with microsurgical suture after craniopharyngioma resection. Among the three cases with internal carotid artery fusiform aneurysm, 1 case underwent craniopharyngioma resection after internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm; 1 case only underwent internal maxillary artery-radial artery-middle cerebral artery bypass and isolation of the aneurysm for non-recurrence tumor; 1 case underwent craniopharyngioma resection and dynamic observation of aneurysm. One case with a cystic aneurysm of the middle cerebral artery was clipped and the craniopharyngioma did not relapse.Results:All patients had no serious postoperative complications. During the follow-up period, there was no recurrence of craniopharyngioma, no recurrence of treated aneurysms, and the stability of aneurysms was observed.Conclusions:Inflammatory stimulation of craniopharyngioma cystic fluid and operation itself are the important reasons for the occurrence of aneurysms after craniopharyngioma surgery. Choosing appropriate surgical methods can complete the removal of craniopharyngioma and the treatment of aneurysms at one time.

Objective:To analyze the incidence and prognosis of epilepsy in frontotemporal lobe glioma.Methods:The clinical data of 208 patients with frontotemporal lobe gliomas in Sanbo Brain Hospital Capital Medical University from 2019 to 2021 were analyzed retrospectively. According to the 2016 World Health Organization (WHO) classification of tumors of the central nervous system, the incidence of epilepsy, Modified Rankin Scale (MRS) score, and Engel Outcome Scale of patients with different grades of tumors were calculated.Results:Among all the patients with frontotemporal lobe gliomas, there was more males than females, and it was more common in the 40 -59 age group. The incidence of epilepsy associated with WHO grade Ⅰand Ⅱ glioma was 100.0% (33/33) and 60.9% (14/23), respectively, while that of WHO grade Ⅳ glioma was 19.0%(19/100). The average follow-up time was (22 ± 9) months. During the follow-up period, the incidence of WHO grade Ⅰ, Ⅱ and Ⅲ glioma-related epilepsy decreased significantly. There was no significant difference in the incidence of glioma-related epilepsy between the total and subtotal resection groups ( P>0.05). There was no statistical correlation between the side of tumor occurrence and the occurrence of epilepsy ( P>0.05), also between the gene phenotype and the occurrence of epilepsy ( P>0.05). There was no significant difference in the Engel Outcome Scale among different grades of gliomas ( P>0.05). The prognosis of patients with Engel Outcome Scale Class 1 was significantly better than that of other grades. Conclusions:The incidence of glioma-related epilepsy is negatively correlated with tumor grade. Age and sex are risk factors for glioma-related epilepsy. The incidence of postoperative epilepsy in patients with low grade glioma is significantly lower than that in patients with high grade glioma, and the prognosis is better. However, there is no significant difference in the Engel Outcome Scale among different grades of gliomas.

Objective:To analyze the safety and therapeutic efficacy of laparoscopic pancreaticoduodenectomy (LPD) and laparoscopic total pancreatectomy (LTP) in the treatment of pancreatic cancer.Methods:Clinical data of 87 patients with pancreatic head and neck cancer who underwent LPD or LTP in the Department of General Surgery at Peking Union Medical College Hospital from December 2018 to August 2023 were retrospectively analyzed. The surgical approach, operative time, intraoperative blood loss volume, conversion rate to open surgery, perioperative mortality, re-operative rate, rate of major postoperative complications, postoperative hospital stay, number of lymph nodes harvested, tumor pathological stage, R 0 resection rate, initiation of postoperative chemotherapy and survival outcomes were recorded. The follow-up period extended until September 2023. Results:Among the 87 patients, 78(89.7%) underwent LPD and 9(10.3%) underwent LTP. PV-SMV vascular resection and reconstruction was performed in 16 cases (18.4%), and 11 cases totally underwent laparoscopy. Five cases (5.7%) required conversion to open surgery. The mean operative time was 279.8±74.0 minutes, and the mean intraoperative blood loss volume was 520.1±743.2 ml. The overall length of hospital stay was 15.9±6.3 days, with a mean postoperative hospital stay of 11.5±6.0 days. The rate of major postoperative complications was 19.5%, including 4 cases (4.6%) of postoperative bile leakage, 6 cases (6.9%) of postoperative gastric emptying disorders, and 3 cases (3.4%) of postoperative bleeding. There was one case (1.1%) with secondary surgery and one case (1.1%) with perioperative death. Among LPD patients, 5 cases (6.4%) had postoperative grade B or higher pancreatic fistula. Advanced age (≥70 years) did not increase the incidence of perioperative complications. All patients achieved R 0 resection. The mean number of lymph nodes harvested was 25.9±11.4. The median time to initiation of postoperative chemotherapy was 2.13±1.43 months. The median overall survival was 16 months. Conclusions:In a high-volume center for pancreatic diseases, LPD and LTP are safe and feasible for the treatment of pancreatic cancer, which could achieve satisfactory anti-tumor efficacy and improve patients' prognosis.
