Objective To study the relationship between voice acoustic analysis(VAA) and voice handicap index (VHI) in patients with vocal cord polyps,and to investigate the characteristic of the VHI.Methods 35 subjects with normal voice and 35 patients with vocal cord polyps underwent VHI,were tested by VAA.Results The parameters such as APQ、jitter、shimmer、NHR in patients with vocal cord polys were much higher than those in the normal voice group.The average score of VHI was 43.32?4.66,while the average score of the normal voice group was 12.51?1.88.There was no correlation between VHI and VAA.Conclusion Since there is no correlation between VHI and VAA in patients with vocal cord polys.One can not speculate the VHI score by the voice acoustic analysis.

ObjectiveTo evaluate the efficacy and safety of 7 atypical antipsychotics combined with selective serotonin reuptake inhibitors（SSRIs） in the treatment of refractory obsessive-compulsive disorder by network Meta-analysis. MethodsRandomized controlled trials （RCTs） about atypical antipsychotics and SSRIs in the treatment of refractory obsessive-compulsive disorder were searched in CNKI， Wanfang Data， VIP， CBM， PubMed， Embase and Cochrane Library databases from inception to June 2020. Based on inclusion and exclusion criteria， the literature screening， date extraction and assessing risk of bias were performed by two researchers independently. Then all statistical analyses were performed using Stata 15.0 software. ResultsA total of 36 RCTs covering 7 atypical antipsychotics and 2 362 patients were included. Network Meta-analysis showed that the surface under the cumulative ranking （SUCAR） of total response rate was the largest in Olanzapine + SSRIs， followed by Paliperidone + SSRIs， Amisulpride + SSRIs， Risperidone + SSRIs， Quetiapine + SSRIs， Ziprasidone + SSRIs， Aripiprazole + SSRIs， SSRIs， and Placebo + SSRIs in turn. In terms of Hamilton Anxiety Scale （HAMA） score， the SUCAR was the largest in Amisulpride + SSRIs， followed by Aripiprazole + SSRIs， Quetiapine + SSRIs， Risperidone + SSRIs， and SSRIs in turn. In terms of Treatment Emergent Symptom Scale （TESS） score， the SUCAR was the largest in Amisulpride + SSRIs， followed by SSRIs， Paliperidone + SSRIs， Quetiapine + SSRIs， Ziprasidone + SSRIs， Risperidone + SSRIs， Aripiprazole + SSRIs， and Placebo + SSRIs in turn. ConclusionCompared with single application of SSRIs， its combination with atypical antipsychotics achieves better efficacy and higher safety in treating refractory obsessive-compulsive disorder， with Olanzapine+SSRIs being the most effective and Amisulpride+SSRIs the safest.

[Objective] To analyze the serological characteristics and molecular biology results for a P^k phenotype. [Methods] One patient with P^k phenotype upon unexpected antibodies at Jining Blood Center in July 2022 was selected as the study subject. The blood groups and unexpected antibodies of the proband and his second son were identified using serological methods. The sequences of 3-β-N-acetylgalactosaminyltransferase gene (B3GALNT1) and the coding region of α-1,4-galactosyltransferase gene (A4GALT) were amplified and analyzed by PCR direct sequencing, and haploid sequence analysis was carried out on the variant sites of the B3GALNT1 gene. PROVEAN, SIFT, PolyPhen2 and Mutation Taster were used to analyze the effect of mutations on the protein. [Results] Serological test results suggested that the proband was a P2^k type, including anti-P antibody in his serum, and his son was the P2 phenotype. Sequencing analysis revealed that the proband had a compound heterozygous variants of the B3GALNT1 in c. 239T>A (p. Leu80Gln) and c. 433C>T (p. Arg145Ter). Further haploid analysis showed that the c. 239T>A had occurred in one haploid while c. 433C>T was present in the other haploid, and his son carried a heterozygous variant of c. 433C>T (p. Arg145Ter); the proband and his son all have homozygous mutation variants of the A4GALT in c. 903C>G. Bioinformatic analysis also predicted that the mutations were harmful to the protein function. [Conclusion] The compound heterozygous variants c. 239T>A (p. Leu80Gln) and c. 433C>T (p. Arg145Ter) in the B3GALNT1 gene may contribute to the P^k phenotype, of which the c. 239T>A variant has not been reported.

OBJECTIVE: To screen for Jk(a-b-) phenotype among blood donors from Jining area and explore its molecular basis to enrich the rare blood group bank for the region. METHODS: The population who donated blood gratuitously at Jining Blood Center from July 2019 to January 2021 were selected as the study subjects. The Jk(a-b-) phenotype was screened with the 2 mol/L urea lysis method, and the result was confirmed by using classical serological methods. Exons 3 to 10 of the SLC14A1 gene and its flanking regions were subjected to Sanger sequencing. RESULTS: Among 95 500 donors, urea hemolysis test has identified three without hemolysis, which was verified by serological method as the Jk(a-b-) phenotype and demonstrated no anti-Jk3 antibody. The frequency of the Jk(a-b-) phenotype in Jining area is therefore 0.0031%. Gene sequencing and haplotype analysis showed that the genotypes of the three samples were JK*02N.01/JK*02N.01, JK*02N.01/JK-02-230A and JK*02N.20/JK-02-230A, respectively. CONCLUSION The splicing variant of c.342-1G>A in intron 4, missense variants of c.230G>A in exon 4, and c.647_ 648delAC in exon 6 probably underlay the Jk(a-b-) phenotype in the local population, which is different from other regions in China. The c.230G>A variant was unreported previously.

The neuropeptide orexin is widely distributed in the nervous system. Previous studies showed that orexin is involved in the feeding behavior regulation by binding to its receptor 1 (OX1R) and receptor 2 (OX2R) to activate the downstream signaling pathway. Recent studies have demonstrated that the system of orexin and its receptors are also involved in important physiological processes such as sleep-wake, learning and memory, and pathological processes of various neurological diseases. In this review, we summarized the research progress on the function of the orexin and its receptor system in physiological and pathological processes, and revealed the correlation between orexin and nervous system diseases, in order to provide the theoretical guidance for the diagnosis and treatment of the related diseases in the future.

OBJECTIVETo investigate the serological characteristics and the genetic status of the family of H-deficient blood group in Jining area of Shandong province in China.

METHODSABO, H, and Lewis blood groups in 3 probands were screened out by the serological method, and saliva testing was performed on all the individuals. The presence of weak A or B on the RBC was confirmed by using the adsorption-elution procedure.

RESULTSThree cases of H-deficient blood group were identified to be para-Bombay blood group (secretor), out of 3 cases, 2 cases were Bh, 1 case was Ah, and anti-H or anti-HI antibody was detected in their serum.

CONCLUSIONThree cases of H-deficerent blood group are para-Bombay phenotype, among them one proband's parents have been confirmed to be consanguineous relationship.

The present study was aimed to investigate the effect of Janus kinase 3 (JAK3) on the migration of breast cancer cells and the underlying mechanism. The expression of JAK3 in breast cancer MCF-7 cells was silenced by siRNA (siJAK3). The migration ability of MCF-7 cells was detected by scratch test. The activity of store-operated calcium channel (SOCC) was detected by fluorescence calcium imaging. The expression levels of Orai1 and STIM1, key molecules in the process of store-operated calcium entry (SOCE) were detected by Western blot and RT-PCR. The results showed that 2-APB, an inhibitor of SOCC, could inhibit the migration ability of MCF-7 cells. siJAK3 transfection significantly inhibited the migration ability of MCF-7 cells, decreased the activity of SOCC, and down-regulated mRNA and protein expression levels of Orai1 and Stim1. Over-expression of Orai1 or STIM1 in JAK3-silenced cells restored their migration ability. These results suggest that JAK3 facilitates the migration of breast cancer cells by SOCC.

Objective    To compare the safety and efficacy of simple mitral valve replacement with the third intercostal incision on the right side and the conventional midsternum incision. Methods    From February 2017 to February 2019, heart surgery in the Affiliated Hospital of Jining Medical College completed the first simple mitral valve replacement (MVR) operation in 103 patients, of whom 39 patients were received minimally invasive right third intercostal small incision (a minimally invasive surgery group). There were 10 males, 29 females at average age of 59.51 years. There were 64 patients with MVR via the middle section of the common sternum (a conventional surgery group), 22 males and 42 females, with an average age of 60.22 years. Types of lesions: 65 patients were with mitral stenosis, 22 patients with incomplete closure, 16 patients with incomplete closure. Results    There was no significant difference in preoperative clinical data between the two groups (P>0.05). The entire group of patients successfully completed the operation. Surgical replacement of mitral valve mechanical valve in 74 patients and biological valve in 29 patients. There was no significant difference between the two groups in the extracardiopulmonary cycle time, aortic blockade time and total hospitalization time. In the early stage of operation, 3 patients were examined for secondary hemostasis, 1 patient was minimally invasive surgery, and the remaining 2 patients were with routine surgery. The infection of incision occurred in 3 patients, all of them were in the routine operation group. All three patients died early after operation in the routine operation group: two were postoperative low cardiac volumetric syndrome leading to multiple organ failure, and the other was sternum infection accompanied by artificial valve endocarditis. Conclusion    There is no significant difference between MVR through the third rib of the right chest and traditional MVR in the safety. However, it has the advantages of small trauma, beauty, low incidence of incision infection and reduced postoperative pain.

OBJECTIVE: To explore effect of short-segment pedicle screw internal fixation combined with hyperbaric oxygen in treating acute spinal fractures and its influence on recovery of spinal nerve function. METHODS: A total of 96 patients with acute spinal fracture admitted from February 2017 to March 2020 were divided into combined group and control group, with 48 cases in each group. Both groups were treated with short-segment pedicle screw internal fixation. The combined group was given hyperbaric oxygen after surgery. The operation time, surgical blood loss, incision length and other general operation conditions between two groups were recorded. The differences in spinal morphology and function, Ameraican Spinal Injury Assiciation(ASIA) neurological function grade, serum inflammatory factors and ability of daily living activities were observed before and after surgery. RESULTS: There was no significant difference in operation time, surgical blood loss, and incision length between combined group and control group(P>0.05). There were no significant differences in anterior height ratio and Cobb angle between two groups before surgery, 1 week and 6 months after surgery(P>0.05). The height ratio of anterior margin of the injured spine was significantly improved in both groups at 1 week and 6 months after surgery compared with preoperative period (P<0.05), and Cobb angle was significantly reduced in both groups compared with preoperative period (P<0.05). There was no statistically significant difference in serum interleukin-6(IL-6), interleukin-8(IL-8), and tumor necrosis factor-α(TNF-α) levels between two groups at 1 d after surgery(P>0.05);the serum IL-6, IL-8, and TNF-α levels of combined group were lower than those of control group at 1 week after surgery (P<0.05). At 6 months after surgery, ASIA neurological function grade of combined group was C grade in 2 cases, D grade in 23 cases, E grade in 22 cases. In control group, 7 cases was grade C, 26 cases was grade D, 13 cases was grade E, and the difference between two groups was statistically significant(P<0.05). The Barthel score of combined group was higher than that of control group at 1 month and 3 months after surgery, and the difference was statistically significant (P<0.05);at 6 months after surgery, there was no significant difference in Barthel score between two groups(P>0.05). CONCLUSION Short-segment pedicle screw internal fixation combined with hyperbaric oxygen for the treatment of acute spinal fractures is beneficial to the recovery of spinal nerve function after surgery, and has a certain effect on the early improvement of the patients' activities of daily living.

Objective    To analyze the safety and effectiveness of minimally invasive small incision through the right third intercostal and standard aortic valve replacement. Methods    The clinical data of 123 patients with the first simple aortic valve replacement in our hospital from June 2013 to May 2020 were retrospectively analyzed. The patients receiving aortic valve replacement through the right third intercostal small incision were allocated to a minimally invasive group, and patients receiving aortic valve replacement through the median sternal incision were allocated to a common group. The clinical outcomes of the two groups were compared. Results    There were 40 patients in the minimally invasive group, including 11 (27.5%) females and 29 (72.5%) males, aged 54.60±9.98 years with the body mass index (BMI) of 23.16±2.48 kg/m2. There were 83 patients in the common group, including 27 (32.5%) females, 56 (67.5%) males, aged 58.77±9.71 years, with the BMI of 24.13±3.13 kg/m2. Compared with the common group, the aortic cross-clamping time, cardiopulmonary bypass time, and operation time were longer (P<0.05), the ventilator support time was shorter (P<0.05), and the blood loss, postoperative 24 h chest drainage volume and total expense were less (P<0.05) in the minimally invasive group. The ICU stay, postoperative hospital stay, and total hospital stay were not statistically different between the two groups (P>0.05). Conclusion    The aortic valve replacement through the right third intercostal small incision is safe and effective, with less blood loss, 24 h chest drainage volume and invasiveness.
