Objective: To explore the application effect of a guided self help intervention based on dialectical behavior therapy (DBT) to address non suicidal self injury (NSSI) behavior among college students, so as to provide a reference for reducing the occurrence of NSSI behavior in this population. Methods: A total of 106 college students with NSSI admitted to the Department of Child and Adolescent Psychology, the Second Affiliated Hospital of Jining Medical University from January 2021 to January 2023 were selected and divided into an observation group and a control group, with 53 cases in each group, using a random number table method. The control group received routine medication treatment and psychological intervention, while the observation group, on the basis of the interventions provided to the control group, implemented dialectical behavior therapy based guided self help. The approach combines group activities, individual counseling, and selfdirected learning, covering four core modules: mindfulness training, distress tolerance, interpersonal effectiveness, and emotion regulation. Meanwhile, data collection, skill check ins, and personalized recommendation pushes were conducted through a WeChat. Both groups were intervented for 12 weeks. Before the intervention and after the intervention, the Adolescent Non suicidal Self injury Behavior Questionnaire, Ottawa Self injury Inventory (OSI), and Barratt Impulsiveness Scale (BIS) were used to evaluate the patients, and the levels of serum neurotransmitters were detected. The χ 2 test, t test, and Cochran s Q test were used for data comparison and analysis. Results: The incidence rates of NSSI in the observation group after 3, 6, and 12 weeks of intervention were 47.17%, 16.98%, and 5.66%, respectively, all lower than those in the control group (67.92%, 35.85%, 20.75%) ( χ 2=4.67, 4.85, 5.27,all P <0.05). After 12 weeks of intervention, in the NSSI Behavior Questionnaire, the total score of the observation group was (17.94±2.69) points, which was lower than that of the control group (23.04±5.11) points; in the Function Questionnaire, the total score of the observation group was (53.24±8.94) points, which was higher than that of the control group (47.74±8.00) points（both P ＜0.05）. In terms of the OSI, the total score of the observation group was (4.49±0.62) points, lower than that of the control group (6.25±0.81) points;in the BIS, the total score of the observation group was (80.76±7.94) points, lower than that of the control group (87.74±9.34) points，and the differences between groups were statistically significant(both P<0.05). After the intervention, the level of 5-hydroxytryptamine in the observation group was (67.93±5.42) ng/mL, higher than (44.72±5.54) ng/mL of the control group; the levels of substance P and cortisol in the observation group were (35.82±4.47) ng/L and (75.64±8.02) μg/L, respectively, both lower than (48.14±5.32) ng/L and (94.53±10.78) μg/L of the control group, and the differences were statistically significant (all P <0.05). Conclusion The guided self help intervention based on DBT is helpful for reducing NSSI behavior among college students.

Sialidosis is a rare lysosomal storage disease caused by NEU1 gene mutation at 6p21.33. It is characterized by myoclonic, ataxia, epilepsy, and decreased vision. A pair of twins with sialidosis type 1 are reported to enrich clinicians ′ understanding of the disease, so as to improve the diagnosis and treatment. The proband was a 16-year-old male. The main symptom was intermittent limb involuntary trembling for 2 years, with paroxysmal loss of consciousness. Fundus examination showed cherry-red spots. His twin brother had similar symptoms, but the overall performance was mild. Whole exome sequencing results showed that both patients carried compound heterozygous mutations of c.239C>T (p.P80L) and c.803A>G (p.Y268C) in NEU1 gene, which were from their normal phenotype mother and father.

ObjectiveTo compare and observe the effect of Reduning injection （mainly clearing heat）， Shenfu injection （mainly warming Yang） combined with gefitinib on the proliferation， apoptosis， stemness characteristics and metabolism of lung cancer cells. MethodDifferent non-small cell lung cancer （NSCLC） cell lines were selected and intervened with gefitinib （5， 10， 20 μmol·L^-1）， Reduning injection （0.6%， 0.9%）， Shenfu injection （0.6%， 0.9%）， gefitinib combined with Reduning injection， and gefitinib combined with Shenfu injection. Cell proliferation in each group was detected by cell counting kit-8 （CCK-8） assay， and cell apoptosis was detected by flow cytometry. The mRNA and protein expressions of lung cancer stem cell markers sex determining region Y-box 2 （Sox2） and aldehyde dehydrogenase family 1 member A1 （ALDH1A1） were determind by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The redox ratio of lung cancer cells was observed by femtosecond label-free imaging （FLI） and energy metabolism instrument was used to determine the glycolysis level in cells. ResultCompared with the blank group， Reduning injection reduced the survival rate of lung cancer cells （P<0.05）， increased the apoptosis rate （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， and up-regulated the redox ratio of cells （P<0.05）， while Shenfu injection exerted no remarkable effect on the above indexes. In addition， compared with gefitinib alone， Reduning injection combined with gefitinib inhibited the survival rate of lung cancer cells （P<0.05）， promoted the cell apoptosis （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， up-regulated the redox ratio of cells （P<0.05）， and lowered the proton efflux rate of glycolysis （P<0.05）， while Shenfu injection combined with gefitinib failed to affect these indexes of lung cancer cells significantly. ConclusionReduning injection may inhibit stemness characteristics of tumor cells by regulating their metabolism to enhance the proliferation-inhibiting and pro-apoptotic effects of gefitinib on lung cancer cells， while Shenfu injection had no significant enhancing effect on gefitinib. This indicates that epidermal growth factor receptor tyrosine kinase inhibitors （EGFR-TKIs） should be used in combination with heat-clearing Chinese medicines.

ObjectiveTo observe the therapeutic effect of Wang's Yijing decoction combined with conventional therapy on the treatment of polycystic ovary syndrome （PCOS） with kidney deficiency and phlegm-dampness syndrome and its regulating effect on the intestine-brain axis. MethodThe 132 patients from the gynecological clinic of Shanxi Bethune Hospital were randomly assigned into a control group and an observation group， with 66 patients in each group. The patients in the control group were treated with drospirenone and ethinylestradiol tablets and metformin tablets， and those in the observation group were administrated with Wang's Yijing decoction on the basis of the therapy in the control group. The treatment in both groups lasted for 3 menstrual cycles. The changes in menstrual blood volume， color， and texture， as well as that in the menstrual cycle before and after treatment were scored. Further， the Rosenfield， hirsutism， and kidney deficiency and phlegm-dampness syndrome were scored before and after treatment. Pelvic ultrasound was performed before and after treatment to compare the bilateral ovarian volume. The levels of anti-mullerian hormone （AMH）， estradiol （E₂）， luteinizing hormone （LH）， follicle-stimulating hormone （FSH）， testosterone （T）， dihydrotestosterone （DHT）， and sex hormone-binding globulin （SHBG） were measured before and after treatment， and the free androgen index （FAI） was calculated. After the fasting insulin and fasting blood glucose were examined before and after treatment， the homeostatic model assessment of insulin resistance （HOMA-IR） was calculated. The levels of ghrelin， glucagon-like peptide-1 （GLP-1）， peptide tyrosine-tyrosine （PYY） in serum and short-chain fatty acids （SCFAs） in fresh stool were measured before and after treatment. ResultThe treatments in both groups lowered the scores of irregular menstruation， Rosenfield， hirsutism， and kidney deficiency and phlegm-dampness syndrome （P<0.01）， and the scores in the observation group were lower than those in the control group （P<0.01）. After treatment， the T， DHT， FAI， AMH， E₂， LH， and FSH levels lowered （P<0.01）， while the SHBG level elevated （P<0.01）. In addition， the AMH， E₂， LH， T， DHT， and FAI in the observation group were lower than those in control group， while the SHBG level presented an opposite trend （P<0.01）. After treatment， the bilateral ovarian volume and HOMA-IR of the two groups decreased （P<0.01）， and were lower in the observation group than in the control group （P<0.05， P<0.01）. The treatments in both groups elevated the levels of ghrelin， GLP-1， PYY， and SCFAs （P<0.01）， which were higher in the observation group than in the control group （P<0.01）. After treatment， the recovery rate in the observation group was 65.57% （40/61）， which was higher than 44.83% （26/58） in the control group （χ²=5.180， P<0.05）. ConclusionWang's Yijing decoction combined with conventional western medicine treatment can regulate the intestine-brain axis， endocrine and metabolic disorders， and sex hormones， adjust the menstrual cycle， and alleviate clinical symptoms， demonstrating good clinical effect for the PCOS patients with kidney deficiency and phlegm dampness syndrome.

With the development of high-throughput sequencing technology, circular RNAs (circRNAs) have gradually become a hotspot in the research on non-coding RNA. CircRNAs are produced by the covalent circularization of a downstream 3' splice donor and an upstream 5' splice acceptor through backsplicing, and they are pervasive in eukaryotic cells. CircRNAs used to be considered byproducts of false splicing, whereas an explosion of related studies in recent years has disproved this misconception. Compared with the rich studies of circRNAs in animals, the study of circRNAs in plants is still in its infancy. In this review, we introduced the discovery of plant circRNAs, the discovery of plant circRNAs, the circularization feature, expression specificity, conservation, and stability of plant circRNAs and expounded the identification tools, main types, and biogenesis mechanisms of circRNAs. Furthermore, we summarized the potential roles of plant circRNAs as microRNA (miRNA) sponges and translation templates and in response to biotic/abiotic stress, and briefed the degradation and localization of plant circRNAs. Finally, we discussed the challenges and proposed the future directions in the research on plant circRNAs.

Cronbach's α coefficient of the scale was 0.972, Cronbach's α coefficient of dimensions of knowledge, attitude and practice were respectively 0.957, 0.943 and 0.965, and the test-retest reliability coefficient was 0.893. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 63.918%.Conclusions:Nurses' Knowledge, Attitude and Practice Scale of Pulmonary Rehabilitation for COPD has good reliability and validity, which can objectively and effectively evaluate the knowledge, attitude and practice level of nurses in COPD pulmonary rehabilitation and provide a reference for formulating pulmonary rehabilitation specialist training plans.

Objective: Vascular endothelial growth factor A (VEGFA) was investigated as the key protein which might promote the specific metastasis progress of nasopharyngeal carcinoma. Methods: Sixteen specimens of pulmonary metastasis carcinoma and counterparts in primary nasopharyngeal carcinoma tissue were collected from patients. The expression of VEGFA through immunohistochemistry was investigated.VEGFA was knocked down by siRNA in two cell lines of nasopharyngeal carcinoma (CNE-1 and 5-8F), MTT and Transwell test were used to explore the role of VEGFA in praxiology. Then shRNA was used to cultivate the stable CNE-1 cell line with down-regulated-expression of VEGFA. The nude mice models were built through tail vein injection of specific nasopharyngeal carcinoma cells, and lungs were collected to perform further metastasis analysis. Results: Previous genetic studies showed that VEGFA had higher expression in metastasis tissue, and the result was validated in the present study using immunohistochemistry. The percentage of positive cells was 84.8% in pulmonary metastasis group, 51.5% in primary tissue group (t=8.639, P<0.05), average optical density was 0.154 in pulmonary metastasis group, 0.061 in primary tissue group (t=18.791, P<0.05). Low expression of VEGFA inhibited cell viability of optical density value of CNE-1 in siRNA gourp was 0.715, 0.902 in control group (t=7.274, P<0.05); 5-8F in siRNA group was 0.715, 0.935 in control group (t=7.751, P<0.05). Number counting suppressed migration of CNE-1 in siRNA group was 52 per high-power lens, 124 per high-power lens in control group (t=29.380, P<0.05), 5-8F in siRNA group was 65 per high-power lens, 155 per high-power lens in control group (t=18.181, P<0.05). Number counting invasion of CNE-1 in siRNA gourp was 38 per high-power lens, 86 per high-power lens in control group (t=27.665, P<0.05), 5-8F in siRNA group was 52 per high-power lens, 116 per high-power lens in control group (t=40.972, P<0.05) in vitro. Furthermore, knock-down of VEGFA in nasopharyngeal carcinoma reduced the pulmonary metastasis in vivo. Number counting of tumor volumes in shRNA group was 2.4, and 11.0 in control group (t=6.143, P<0.05); average optical density of immunohistochemistry in shRNA group was 0.033, and 0.176 in control group (t=15.734, P<0.05). Conclusions Results above reveal the overexpression of VEGFA in nasopharyngeal carcinoma can facilitate the pulmonary metastasis. Targeting VEGFA may provide a new biomarker of clinical study.

ObjectiveTo establish a green passage for elderly patients with hip fracture, and explore the feasibility and nursing mode of establishing an independent orthopedics unit for elderly patients with hip fracture. Methods? From January 2017 to June 2018, a total of 391 cases of elderly patients with hip fracture in the Second Affiliated Hospital of Wenzhou Medical University were selected. The patients were divided into two groups according to their admission to the ward. The 213 patients in the elderly hip fracture independent orthopedics unit group were admitted to the emergency green channel; 178 patients in the general orthopedics ward were given routine treatment and nursing. The time interval from admission to operation and the prognosis were compared between the two groups. Results? 77.46% of the elderly patients in the independent orthopedics unit group received operation within 36 hours after admission, while only 29.21% in the general orthopedics ward group, with statistical significance (P＜ 0.01). Rehabilitation and discharge rate of independent orthopaedic unit group was 89.20% and 77.53% in control group within one week after operation. The difference was statistically significant (P=0.009). Conclusions? The establishment of independent orthopedics unit with green channel in geriatric orthopedics reduces the waiting time, bed rest and hospitalization time of patients, and saves medical and nursing resources.

Objective: To observe the changes of peripheral blood picture of CHB with Peg-IFN, and explored the relationship between the changes and decline of HBV DNA, clearance of HBsAg. Methods: Patients with CHB treated with Peg-IFN α-2 a in the Second Division of Liver Disease in Beijing Ditan Hospital were monitored for blood routine examination and Liver function, kidney function, thyroid function of baseline and weeks 2, 4, 8, 12, 24, 36, 48, and weeks 12, 24, and 48 after the end of treatment for chronic hepatitis B, and HBV DNA, HBsAg. Results: The decrease of peripheral blood cells began to occur at week 2 of treatment. For CHB with HBeAg negative patients, white blood cells, lymphocyte, neutrophils, hemoglobin and platelets significantly decreased at 2 weeks, while a minimum value occurred at 48 weeks. The recovery was obvious at the end of treatment (48 weeks), and reached pre-treatment levels at 48 weeks after the end of treatment. For CHB with HBeAg positive patients, white blood cells, neutrophils, hemoglobin and platelets significantly decreased at 2 weeks, while a minimum value was found at 36-48 weeks. The recovery was obvious at the end of treatment (48 weeks), and reached pre-treatment levels at 48weeks after the end of treatment. For patients with CHB, hemoglobin declined by more than13.64% at 36th week, which means that the patient would have a predictive significance for decrease of HBV DNA, and drops of more than 0.33% at 2nd week means that the patient would have a predictive significance for clearance of HBsAg. Conclusions During the treatment with interferon, the variation regularity of blood picture for predicting result have a certain effect, which may help predict and monitor the change of blood picture in clinical work.

Objective: To observe the changes of peripheral blood image of chronic hepatitis C (CHC) patients treated with pegylated interferon (Peg-IFN) and ribavirin, and explore the relationship between the changes and serum virological respose (SVR). Methods: Patients with CHC treated with Peg-IFN α-2 a and ribavirin in the Second Division of Liver Disease in Beijing Ditan Hospital were monitored for peripheral blood cells routine examination and Liver function, kidney function, thyroid function at baseline and week 2, 4, 8, 12, 24, 36, 48, and week 12, 24, 48 after the end of treatment for chronic hepatitis C, and HCV RNA. Results: The decrease of peripheral blood cell counts began to appear at week 2 of treatment. For CHC patients without cirrhosis, white blood cells, lymphocyte, hemoglobin and platelets at week 2, while minimum values were seen at week 36, and the neutrophils reached the minimum value to at week 24. Significant recovery of the peripheral blood changes was seen at the end of treatment (48 weeks), and reached pre-treatment levels at week 48 after the end of treatment. For CHC patients with cirrhosis, white blood cells, lymphocytes, hemoglobin and platelets significantly decreased at week 2, while neutrophils reached a minimum value at 2 weeks. And hemoglobin and platelets reached a minimum value at 24 weeks, and the white blood cells reached the minimum value at weeks 24-36 besides lymphocyte reached the minimum value at week 36. Significant recovery was seen at the end of treatment (48 weeks), and the blood cell counts reached pre-treatment levels at 48 weeks after the end of treatment. For patients with CHC, hemoglobin decreased by more than 27.47% at week 4, which means that the patient would have a predictive significance for SVR, as well as the of PLT reduction by more than 36.96% at week 8.
