Objective To investigate the characters of morphology change and protein expres-sion in progressed renal cell carcinoma after the treatment of sorafinib. Methods Clinical data of 2 cases with progressed renal cell carcinoma treated with sorafenib were collected. The HE slices were reviewed. Immunochemistry was used to detect the expression of Vimentin, AE1/AE3, CK7, CK8, CK18, CD10, VEGF, VEGFR2, p53 and Ki-67 levels. Results There was no difference in patho-logic type between before and after the therapy of sorafenib. Both of the 2 cases were showed degener-ation in tumor cell in different degree with fibrosis and necrosis. The expression of renal cell carcinoma related antigens (Vimentin, AE1/AE3, CK7, CK8, CK18 and CD10) had no difference before and af-ter the treatment of sorafinib. The expressions of VEGF, VEGFR2, p53 and Ki-67 were increased, and the expression of Bcl-2 was decreased after the therapy of sorafinib. Conclusions There may be some morphologie differences between the metastatic tumor or the recurrent tumor and primary tumor because of the treatment of sorafenib. However the pathologic type is the same before and after the treatment of sorafenib. The main differences are the degeneration of the tumor cell and fibrosis after the treatment of sorafenib. The expression changes of VEGF and VEGFR2 may be related to the sor-afenib application.

OBJECTIVE:To evaluate the effect of psychological intervention based on pharmaceutical care on the communi-ty patients with essential hypertension. METHODS:172 patients with essential hypertension in a community health service certer in Nanjing Gulou area in 2013 were divided into control group(n=87)and intervention group(n=85)by simple random meth-od. Control group received conventional antihypertensive drugs and management,intervention group additionally received pharma-ceutical care and psychological intervention,it lasted 6 months. Blood pressure controlling,drug compliance,mastery of drug knowledge and health status in 2 groups before and after treatment were compared. RESULTS:Before treatment,there were no significant differences in the systolic blood pressure(SBP)and diastolic blood pressure(DBP)between 2 groups(P>0.05);af-ter treatment, SBP and DBP in 2 groups were lower than before,SBP and DBP in intervention group were lower than control group,the decrease degree of SBP and DBP was bigger than control group,the differences were statistically significant (P<0.01). 1 month after the beginning of intervention,there was no significant difference in the proportion of drug compliance be-tween 2 groups (P>0.05);1 month after the end of the intervention,the proportion of drug compliance in intervention group was higher than 1 month after the beginning of intervention and control group,the differences were statistically significant(P<0.05). Before treatment,there was no significant difference in mastery of drug knowledge between 2 groups (P>0.05);after treatment,the proportion of patients showed good and excellent mastery of drug knowledge was higher than before and control group,the differences were statistically significant (P<0.05). Before treatment,there were no significant differences in scores of physical,mental,social health subscale and SRHMS between 2 groups(P>0.05);after treatment,scores of physical health subscale and SRHMS in control group,each subscale and to-tal scale scores in intervention group were higher than be-fore, and scores of mental, social health subscale and SRHMS in intervention group were higher than control group, the differences were statistically significant (P<0.05). CONCLUSIONS: The psychological intervention based on pharmaceutical care can effectively promote the con-trol of blood pressure,improve drug compliance,mastery of drug knowledge,health status and mental situation,which is worth of popularizing and applying in community health services.

Objective To investigate the molecular genetic causes and their characteristics of deafness from patients with nonsyndromic hearing loss in Gansu province.Methods Peripheral blood samples were obtained from a total of 375 patients with nonsyndromic hearing loss to extract genomic DNA.Three genes of GJB2, mitochondrial DNA 12SrRNA, and SLC26A4 were screened for mutations in our study cohort using SNPscan technology.Results Among 375 patients, 23 patients were found to carry the homoplasmic mtDNA12SrRNA A1555G mutation, and 2 patients were detected to carry the homoplasmic mtDNA12SrRNA C1494T mutation.Forty-two cases(11.2%) were caused by GJB2 mutations, including 31cases(8.3%) of homozygous mutations, 11 patients(2.9%) of compound heterozygous mutations, and 25 cases(6.7%) of single homozygous mutations.c.235delC was the most prevalent GJB2 mutation with the allele frequency of 8.8%.Twenty-nine cases (7.7%) were caused by SLC26A4mutations, including 17cases(4.5%) of homozygous mutations, 12 patients(3.2%) of compound heterozygous mutations, and 16 cases(4.3%) of single homozygous mutations.c.919-2A>G and c.2168A>G were the most common SLC26A4 mutation, the allele frequencies were 5.2% and 2.0%, respectively.Conclusion A high incidence of mtDNA12SrRNAA1555G mutation is found in nonsyndromic hearing loss patients from Gansu province, while the incidence of GJB2 and SLC26A4 mutations is similar to the level of the overall Chinese deaf population.These findings demonstrate that a total of 25.6% of deaf patients have inherited hearing impairment caused by GJB2, SLC26A4, and mitochondrialDNA12SrRNA mutations.As a result 36% patients and family member can acquire effective genetic counseling.

In order to identify genes involved in floral transition and development of the orchid species, a full-length APETALA1/FRUITFULL-like (AP1/FUL-like) MADS box cDNA was cloned from Cymbidium faberi (C. faberi) sepals and designated as C. faberi APETALA1-like (CfAP11], JQ031272.1). The deduced amino acid sequence of CfAP11 shared 84% homology with a member of the AP1/FUL-like group of MADS box genes (AY927238.1, Dendrobium thyrsiflorum FUL-like MADS box protein 3 mRNA). Phylogenetic analysis shows that CfAP11 belonged to the AP1/FUL transcription factor subfamily. Bioinformatics analysis shows that the deduced protein had a MADS domain and a relatively conservative K region. The secondary structure of CfAP11 mainly consisted of alpha helices (58.97%), and the three-dimensional structure of the protein was similar to that of homologues in Roza hybrida, Oryza sativa and Narcissus tazetta. Real-time quantitative PCR (qRT-PCR) results reveal low levels of its mRNA in roots, lower levels in leaves during reproductive period than vegetative period, and higher levels in pedicels at full-blossom stage than at bud stage. These results suggest that CfAP11 is involved in floral induction and floral development. Additionally, we observed higher levels of CfAP11 expression in pedicels and ovaries than in other tissues during full-blossom stage, which suggests that CfAP11 may also be involved in fruit formation in certain mechanism.

To identify spatiotemporal expression patterns of vernalization genes in common wheat, we analyzed expression characteristics of several vernalization genes (VRN1, VRN2 and VRN3) in the wheat cultivars 'Chinese spring' and 'Luohan 2' by RT-PCR. The VRN1 gene was expressed at different levels in the leaves and roots at the 3-leaf stage, stems, flag leaves at the grain-filling stage, anthers, ovules, and developing seeds in 'Chinese spring'. Expression of VRN1 increased before flowering date, then decreased after flowering time. Expression of VRN1 was not detected in dry seeds or seeds germination. Expression patterns of VRN1 in 'Luohan 2' were similar to those in 'Chinese spring', except that it was not expressed in roots or in the leaves at the 3-leaf stage in 'Luohan 2'. Expression of VRN2 was only detected in the leaves at the 3-leaf stage and in the embryo buds during seeds germination. The Spatiotemporal expression of VRN3 was similar to that of VRN1, except that VRN3 was not expressed in roots. These results improved our understanding of the molecular regulation of vernalization genes in common wheat.

Objective To explore the immune response of T helper cells 17 in patients with hepatitis B virus (HBV) and the relation with Th1,Th2 and Treg cells.Methods The percentages of Th17 cells were detected by intracellular cytokine staining with flow cytometry.Using Realtime PCR method,we assayed the mRNA expression of IL-17,T-bet,GATA-3 and FoxP3 in 58 HBV patients and 40 healthy controls in our research.Results Compared with control group (3.56％ ± 1.26％),the percentage of Th17 cells in the peripheral blood of HBV group (4.72％ ± 1.80％) was higher (P ＜0.001).The mRNA of IL-17 expression of the HBV group (4 ±0.49) was higher than in healthy control group (1.19 ±0.19,P ＜ 0.0001).The mRNA of T-bet expression of the HBV group (2.27 ± 0.24) was higher than in healthy control group (1.10 ± 0.13,P ＜ 0.05).The mRNA of GATA-3 expression of the HBV group (2.29 ± 0.16) was higher than in healthy control group (1.10 ± 0.10,P ＜ 0.0001).The mRNA of FoxP3 expression of the HBV group (2.03 ±0.15) was higher than in healthy control group ((1.05 ±0.10,P ＜ 0.0001).Conclusions The Th17 cells participated in immune response of the hepatitis B virus infection patients,and there has certain adjustment relations among Th1,Th2 and Treg cells.

Objective:To explore the composition and trajectory of symptom clusters during perioperative period in middle-aged and elderly patients with gynecological malignant tumors, so as to provide reference for formulating symptom management programs.Methods:From December 2022 to September 2023, convenience sampling was used to select 145 middle-aged and elderly patients with gynecological malignant tumors who underwent surgical treatment at the Affiliated Cancer Hospital of Xinjiang Medical University as the study subject. A longitudinal survey was conducted on patients at four time points [1 day before surgery (T1), 1 day after surgery (T2), 3 days after surgery (T3), and 7 days after surgery (T4, before discharge) ] using the General Information Questionnaire and the Chinese version of the Anderson Symptom Inventory-Perioperative Module in Patients with Gynecological Cancer.Results:A total of 145 questionnaires were distributed, and 130 valid questionnaires were collected, with an effective response rate of 89.66% (130/145). Exploratory factor analysis extracted six symptom clusters, namely perimenopausal symptom cluster, psychological symptom cluster, fatigue-pain symptom cluster, gastrointestinal symptom cluster, energy deficiency symptom cluster, and surgery related symptom cluster. Perimenopausal symptom group was a specific symptom cluster of gynecological malignant tumor patients, existing at T1. Psychological symptom cluster persisted during the patient's perioperative period. Fatigue-pain symptom cluster and surgery related symptom cluster existed at T2 to T4. Gastrointestinal symptom cluster and energy deficiency symptom cluster existed at T2 and T3.Conclusions:Middle aged and elderly patients with gynecological malignant tumors have various symptoms during the perioperative period, and the symptoms can cluster at different time points. The number of symptom clusters increases with the progress of surgical treatment, while the core symptoms within the cluster remain relatively stable over time. Clinical nursing staff should pay attention to the dynamic changes in the patient's perioperative symptom cluster, adopt efficient and targeted management measures based on the trajectory of symptom clusters, and reduce the burden of perioperative symptoms on patients.

Objective: To analyze the expression of programmed death ligand 1 (PD-L1) in patients with advanced lung adenocarcinoma and the consistency of four PD-L1 immunohistochemical detection platforms, with an aim of establishing baseline information to predict and select patients for programmed death 1 (PD-1)/PD-L1 immune inhibitor therapy. Methods: This was a multi-center retrospective study, collecting totally 57 advanced lung adenocarcinoma biopsy specimens from four centers from August 2017 to December 2017.The mean age of 57 patients was 59 (range 34-81) years, and 29 cases were male, 28 cases were female. Four PD-L1 immunohistochemical stains were done for each case, including 22C3 (Dako), 28-8 (Abcam), SP263 (Ventana), and SP142 (Ventana). Among them, 22C3 staining was done using Dako autostainer, and for the other three antibodies, Ventana Ultraview detection system and autostainer was used. The immunohistochemical slides were read by two trained histopathologists in a double-blinded way, and the percentage of PD-L1 positive tumor cells was assessed as <1%, 1%-24%, 25%-49% and more than 50%. Results: The Dako 22C3 was used as the standard. There were eight cases in which the PD-L1 staining was more than 50% (14.0%, 8/57). The staining consistency of tumor cells was higher in 22C3, 28-8 and SP263 (ρ=0.729-0.809). The two scoring doctors had a high degree of concordance in PD-L1 positive tumor cells (ρ=0.707-0.896), and this was most noticeable in 22C3 and SP263. Conclusions 22C3, 28-8 and SP263 show high consistency in tumor cell staining. The study can provide an effective basis for screening for potential patient population that may benefit from immunotherapy.

Objective:To investigate the therapeutic mechanism of high-frequency repetitive transcranial magnetic stimulation (rTMS) in treating mild amnestic cognitive impairment (aMCI).Methods:Twenty-five patients with aMCI were randomly divided into an observation group of 13 and a control group of 12. The observation group was given 10-Hz rTMS over the left dorsolateral prefrontal cortex at 80% of the motor threshold-400 pulses a day, 5 times a week for 4 consecutive weeks. The control group received sham stimulation on the same schedule. Before and after the experiment, both groups were evaluated using the Montreal cognitive assessment (MoCA) and received fMRI scans.Results:After the intervention, the average MoCA score of the observation group had improved significantly more compared with that of the control group and compared with before the intervention. According to the fMRI results, regional homogeneity in the right middle frontal gyrus of the observation group had increased significantly, while that of the control group both there and in the left precuneus had decreased significantly.Conclusions:High-frequency rTMS can effectively improve the cognitive function of patients with aMCI and synchronize neuron activity in cognition-related brain regions.

Objective To explore the application value of treatment-related markers PD-L1, PD-L2, CD30, CD23, BCL-2, BCL-6, MUM1 and GATA3 in the diagnosis and prognostic evaluation of primary mediastinal B-cell lymphoma(PMBL). Methods A retrospective study was conducted on 34 patients diagnosed with PMBL, and 31 patients with DLBCL-NOS which was not primary in the mediastinum were taken as control group. The expressions of 8 proteins were detected by IHC staining. Results The median percentages of tumor cells with PD-L1, PD-L2 and CD30 expression in PMBL group were 70% (30%, 90%), 25% (0, 70%) and 17.5% (0, 60%) respectively, which were significantly higher than those in the DLBCL-NOS group (P < 0.05). The positive rates of CD30 and CD23 in PMBL group were 61.76% (21/34) and 76.47% (26/34) respectively, significantly different with those in the DLBCL-NOS group (P=0.000). The survival curve of PMBL patients with CD30 or BCL-6 expression showed a trend of poor prognosis, despite the P value was > 0.05. Conclusion The high expression levels of PD-L1, PD-L2 and CD30 in PMBL are helpful to accurately identify more patients who may respond to immune or targeted therapy. Immunohistochemical staining of PD-L1, PD-L2, CD30 and CD23 is helpful for the differential diagnosis of PMBL and DLBCL-NOS. As candidate prognostic indicators of PMBL, CD30 and BCL-6 should be further studied in a larger number of samples.
