Objective To explore the effects of dignity therapy on self-esteem status and negative emotions of lung cancer patients.Methods A total of 62 lung cancer patients were recruited and divided into experimental and control groups (n =31 each).The control group received routine care while the experimental group additional individualized dignity therapy.And the state self-esteem scale,self-rating anxiety and self-rating depression were used to evaluate the intervention outcomes.Results For both groups,the self-esteem status and negative emotions of the intervention group were significantly better than that those of the control group (self-esteem:61.2 ±4.6 vs.52.6 ±4.1,anxiety:52.2 ±6.8 vs.64.6 ±9.3,depression:51.1 ±7.9 vs.66.2 ±8.7,all P ＜0.05).Conclusion Dignity therapy can improve selfesteem status,decrease the levels of anxiety and depression level and boost quality of life for lung cancer patients.

Objective To investigate the testing capabilities of clinical transfusion laboratories in medical institutions in Beijing for the regulatory authorities to formulate administrative policies in this regard.Methods Experts assigned by Beijing Clinical Transfusion Quality Control Center made on-site inspections at the transfusion laboratories in medical institutions using quality control products.They recorded the complete testing process of the operators as well as the instruments,detection reagents in use and the testing results,with statistics and analysis made to the data so collected.Results The pass rate of these on-site inspections was lower than that of the external quality assessment.Some laboratories failed to complete the testing of the quality control products in time and the actual operations in some laboratories were inconsistent to the guidelines.55.9％ of level Ⅰ hospitals and 25.6％ of level Ⅱ hospitals were found with insufficient and inadequate instruments and process layout to meet the needs of clinical blood transfusion.Some of the technicians were found without sufficient trainings in their professional knowledge and basic skills,resulting in their poor competence against emergency cases and weakness in independent problem solving.In addition,the records of detection process and results were found to be substandard.Conclusions Transfusion laboratories in Beijing need to improve their testing capabilities in general.

Glaucoma is a chronic neurodegenerative disease of the optic nerve accompanied by apoptosis of the retinal ganglion cells, atrophy and depression of the optic nerve, and visual field loss.However, the mechanism of high intraocular pressure and glaucomatous optic neuropathy has not yet been elucidated.Autophagy is a lysosomal degradative process, which eliminates bulk cytoplasmic constituents.In recent years, a large number of studies have shown autophagy to be closely related to the occurrence and development of glaucoma.These studies examined the stress response of ocular tissues to high intraocular pressure, optic nerve protection, optic disc remodeling, immune regulation, abnormal protein removal and scar regulation.This article summarizes the relationship between autophagy and glaucoma, and pays special attention to the progress of research concerning autophagy in the trabecular meshwork, retinal ganglion cells, exfoliation syndrome, and scarring after glaucoma filtering surgery.It will lay a foundation for a deeper understanding of glaucoma pathogenesis and provide a new idea for diagnosing and treating glaucoma in the future.

Objective:To observe the characteristics of early changes in choroidal thickness and choroidal microvascular morphology in the macula of patients with systemic lupus erythematosus (SLE) using swept-source optical coherence tomography angiography (OCTA).Methods:A cross-sectional study was conducted.Thirty-seven patients (37 eyes) who were diagnosed with SLE without obvious ocular symptoms in Hebei General Hospital from January 2022 to July 2022 were enrolled in this study as a SLE group.At the same time, 35 normal adults (35 eyes) matched with age and sex were included as a control group.Swept-source OCT was used to perform a 9 mm×9 mm radial scan of the macular region of subjects to obtain the average choroidal thickness of the macular central concave area, the paracentral concave area (1-3 mm), and the pericentral concave area (3-6 mm). OCTA was used to perform a 3 mm×3 mm scan of the macular region and images of retinal superficial capillary plexus (SCP) and deep capillary plexus (DCP) blood flow density, choroidal capillary plexus (CC) blood flow density, and microvascular blood flow in the macular region were obtained and binarized using ImageJ software (Phansalkar method) to calculate the choroidal capillary flow void area (FDa) and percentage of flow deficits (FD%). The study protocol followed the Declaration of Helsinki and was approved by the Ethics Committee of Hebei General Hospital (No.202310). Informed consent was obtained from all subjects.Results:The choroidal thickness of the subfoveal region in SLE group was (268.73±81.67)μm, which was significantly higher than (230.14±68.14) μm of control group ( t=2.170, P=0.033). The blood flow density of SCP, DCP and CC in the macular central zone area of SLE group were (16.58±3.90)%, (14.25±3.15)% and (51.80±4.27)%, respectively, which were significantly lower than (20.55±4.41)%, (16.57±3.74)% and (54.33±3.41)% of control group ( t=-4.043, -2.851, -2.763; all at P<0.05). The FDa and FD% in SLE group were 3.43(3.25, 3.56)mm 2 and 38.11%(36.13%, 39.52%), which were greater than 3.25(3.21, 3.32)mm 2 and 36.11%(35.64%, 36.84%) of control group, and the differences were statistically significant ( Z=-3.470, -3.476; both at P<0.05). Conclusions:OCTA can detect an increase in choroidal thickness and a decrease in blood flow density of CC in eyes with SLE without obvious ocular symptoms.

Objective:To explore the benefits of speech training for young persons with tongue cancer after 125Ⅰ radioactive seed implantation. Methods:Fifty young persons bearing a 125Ⅰ radioactive seed implanted to treat tongue cancer were given up to 40min of daily tongue function training beginning on the second day after the operation. Abnormal sounds were corrected in the seven days before their discharge. An online platform assisted further training in the family combined with biofeedback. Daily 20-30 minute sessions were prescribed. Time domain waveforms, speech spectra and energy waterfalls were recorded from the 50 subjects before the experiment and after 1 week of the speech training. Intelligibility (PI) was quantified before the operation and the speech training, and then 1, 2, 4 and 6 months after discharge. Results:After 1 week of speech training abnormal waveforms had disappeared from the time domain waveform diagram. Fricative disturbance areas in the speech spectrum diagram had improved significantly, and the energy distribution in the energy waterfall diagram was balanced, showing a trend typical of normal speech fluctuation. The average PI before the operation (39.92±8.46) increased to (40.32±8.79) before the speech training and to (42.78±8.24) one month after discharge. It then continued to improve to (72.32±5.55) 6 months after discharge.Conclusion:Speech training can significantly improve the speech intelligibility of patients with tongue cancer after 125Ⅰ radioactive seed implantation.

【Objective】 To investigate the effect of peripheral blood bile acids on the cognitive function of schizophrenia patients. 【Methods】 Targeted metabolomics was adopted to analyze the total level of primary and secondary serum bile acid metabolites collected from 23 schizophrenia patients and 23 health control individuals. The MATRICS Consensus Cognitive Battery (MCCB) was adopted to evaluate the subjects’ cognitive function in five dimensions. 【Results】 We found that the schizophrenia patients had impaired cognitive functions in multiple dimensions including speed of processing, working memory, reasoning and problem solving, and visual learning. Compared with the health control group, serum levels of cholic acid (CA) and chenodeoxycholic acid (CDCA) were significantly lower in patients with schizophrenia, while serum level of glycocholic acid (GCA) was significantly higher, and the ratio of deoxycholic acid (DCA) to CA was higher (3.04 vs. 1.16). Speed of processing, working memory, reasoning and problem solving, and visual learning abilities were significantly negatively correlated with serum levels of multiple primary bile acids including taurocholic acid (TCA), GCA, glycochenodeoxycholic acid (GCDCA) and taurochenodeoxycholic acid (TCDCA), after adjustments of age, sex, and body mass index. 【Conclusion】 The bile acid profile of schizophrenia patients is obvious, and the decrease in neuroprotective bile acids (namely, CA and CDCA) and the up-regulation of cytotoxic bile acid (i.e., GCA) may impair the cognitive function of schizophrenia patients.

OBJECTIVETo demonstrate the clinical applicability of three-dimensional CT angiography by evaluating the anatomic features and variation of inferior mesenteric artery(IMA) and left colic artery(LCA) in order to provide reference to vessel ligation strategy in laparoscopic rectal cancer surgery.

METHODSClinical and image data of 123 patients receiving abdominal multislice CT at The Sixth Affiliated Hospital from 2014 to 2015 were retrospectively analyzed. The images were 3D-reconstructed with computer 3D CT angiography and arterial enhancement phase images were chosen for analysis. Linear distances from IMA root to abdominal aortic bifurcation and from LCA at IMA root level to IMA root were measured. Branch types of IMA, coursing pattern of LCA, and association between LCA and inferior mesenteric vein (IMV) site were summarized.

RESULTSOf 123 cases, 80 were males and 43 were females, mean age was (46.8±16.6) years, body weight was (57.7±10.4) kg, and BMI was (21.3±3.6) kg/m. The average distance from IMA root to abdominal aortic bifurcation was (42.5±7.9) mm, and this distance was closely associated with body weight (OR=4.771, 95%CI: 1.398 to 16.283, P=0.013). Longer distance tended to appear in the heavier patients. LCA and sigmoid artery (SA) originating from same single IMA was found in 61(49.6%) cases; LCA and SA forking at same point in 35(28.5%) cases; LCA and SA coursing together and forking afterwards in 24(19.5%) cases, and LCA disappearing in 3(2.4%) cases. In 71(57.7%) patients, LCA ascended medial to the lateral border of left kidney, while in 16(13.0%) patients, LCA arranged below the inferior border of left kidney. When the LCA site was higher and the distance from LCA to IMA root was closer [distance from LCA to IMA root level was (24.2±9.9) mm, (30.0±15.2) mm and (66.6±12.3) mm, F=83.2, P<0.001]. At the level of IMA root, LCA located medial to IMV in 21(17.1%) cases, located just lateral to IMV in 54(43.9%) cases, and located lateral and ascended far away from IMV in 48(39.0%) cases.

CONCLUSION3D-CT angiography is non-invasive, efficient and accurate in evaluating coursing features and variation of IMA and its branches, which can provide important reference to the surgeons, promising laparoscopic surgery smooth and safe.
