Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To investigate the clinical and gene variant characteristics of benign familial infantile epilepsy in generations of three families.Methods:The clinical data of the three benign familial infantile epilepsy patients with PRRT2 gene variant who were diagnosed and their family members were collected from Children′s Hospital Affiliated to Zhengzhou University between 2018 and 2019. All coding exons from the patients and their parents were screened by targeted next-generation sequencing, and detected variants were verified by Sanger sequencing.Results:In all the patients, a cluster of seizures was observed before one year old,but interictal clinical conditions were normal. The electroencephalograms were all normal in interictal stage. The father of proband 1 presented with convulsion onset at the age of eight months and showed remission before one year old. The grandpa, mother and uncle of proband 2 also presented with convulsion onset in their babyhood of life and showed remission before one year old. The mother of proband 3 presented with convulsion onset in their babyhood of life and showed remission before three years old. Proband 1 carried heterozygous c.937G>C variant in the PRRT2 gene which is inherited from his father. Proband 2 carried c.1075_c.1076insC variant inherited from his mother. A deletion of PRRT2 gene exon 2 was detected in both of proband 3 and her mother. The three variants had not been reported in the Human Gene Mutation Database.Conclusions:Benign familial infantile epilepsy is a kind of inherited epilepsy characterized by early onset of seizure in babyhood with better prognosis, a cluster of focal seizures with or without secondary generalization, and cessation of seizure mostly before two or three years of age. The variants c.937G>C, c.1075_c.1076insC and the deletion of exon 2 in the PRRT2 gene have enriched the gene variant spectrum of benign familial infantile epilepsy.

Objective To observe the effects of electroacupuncture on the expressions of autophagy related protein Beclin-1 and apoptosis related protein p53 of hippocampus in rats;To explore the mechanism of electroacupuncture on Alzheimer's disease (AD).Methods The rats were randomly divided into the normal group, the sham-operation group, the model group, and the electroacupuncture treatment group. “Baihui” and “Yongquan” points were taken for electroacupuncture treatment and the treatment course was 7 days. The rats were treated once a day for 4 courses. Changes in morphology and number of Nissl positive cells were examined by Nissl staining in hippocampal CA1 regions. Expressions of Beclin-1 and p53 protein were determined by Western blot analysis.Results Number of Nissl positive cells in CA1 region of the model group was significantly less than that of normal group (P<0.01). After electroacupuncture treatment, number of pyramidal cells and expression of Nissl body significantly increased (P<0.05). Expression of Beclin-1 decreased, while expression of p53 increased in the hippocampus of the model group, compared with that in the normal group (P<0.05). However, electroacupuncture treatment could significantly upregulate the expression of Beclin-1 protein (P<0.01), but downregulate the level of p53 (P<0.05).Conclusion Electro-acupuncture treatment could fight against Aβ-induced neuronal apoptosis, and improve the morphological changes of AD’s hippocampus.

ABSTRACT:Objective To explore the application effect of self-made inflatable mattress in thyroid surgery.Methods A total of 100 patients undergoing thyroid surgeries were randomly di-vided into control group and test groups with 50 cases in each of group.The control group was per-formed surgery with foam position pad on mattress with the area from (50×43×8)cm to (50×43 ×12)cm at 20 degree angles.The test group was performed surgery with controllable self-made inflatable mattress.Blood pressure,heart rate in different positions,comfort degree of surgery pa-tient and satisfaction index was recorded.Results There was no significant difference (P >0.05) between control group and test group in blood pressure and heart rate.Blood pressure and heart rate of patients of surgery in test group were lower than that of control group (P <0.05).There were statistically significant differences since comfort degree of surgery patient and satisfaction in-dex in control group were less than that of test group (P <0.05).Conclusion Controllable self-made inflatable mattress could avoid the changes in vital signs and remain a stable hemodynamics and improve comfort degree of patients and satisfaction index.

Objective To explore the protective effects of electro-acupuncture (EA) serum onβ-amyloid protein (Aβ) induced primary rat hippcampal neurons. Methods The rat models of Alzheimer's disease were established by intracerebral injection of Aβ1-40. After treated them with EA, the serum was harvested. Primary cultured hippocampal neurons were treated with Aβ25-35 to establish neuronal damage model in vitro, and divided into normal group, model group and EA serum group. The proliferation of neurons was detected by MTT test. Neuronal apoptosis was examined by TUNEL staining, and expression of cysteine aspartic acid proteases-3 (Caspase-3) was detected by immunocytochemical staining. Results MTT test showed that the cell viability was significantly decreased after treated with Aβ. While compared with the model group, cell proliferation of EA serum group was significantly enhanced (P<0.01). TUNEL staining showed that the number of apoptotic cells in EA serum group decreased significantly compared with the model group (P<0.01). After 48 h of Aβ treatment, Caspase-3 expression levels were significantly elevated. However, compared with the model group, the number of Caspase-3 positive cells in EA serum group was significantly reduced (P<0.01). Conclusion The EA serum could promote the proliferation of hippocampal neurons, reduce the expression of Caspase-3, counteract the neurotoxicity of β-amyloid protein, and reduce neuronal apoptosis.

Objective To study the effect of Danggui Buxue Tang (DBT) on immunological reconstitution of bone marrow transplantation (BMT) in mice. Methods BALB/c mice were irradiated by 137Cs γ once 8.5 Gy, then the mice were engrafted with bone marrow cells (107 cells/mouse) within 4 hours lethal irradiation. And the mice were fed by DBT every day for 15 days. Flow cytometry technique combined with immunological methods were performed to evaluate immunological reconstitution of BMT mice in 30 and 60 days pest-transplantation. Peripheral blood RBC and WBC were counted, and nucleated cells were assayed in recipient bone marrow. Lymphocyte numbers in thymus and periphery were counted and subpopulations of the two origins were observed respectively. Lymphocyte proliferation induced by Con A and LPS, plaque-forming cell (PFC), delayed type hypersensitivity (DTH) were also examined in 30,60 days in post-transplantation respectively. Results Compared with BMT mice, BMT mice treated with a certain dose of DBT could increase the number of peripheral blood RBC and WBC in the recipients, and also could increase that of nucleated cells significantly. BMT mice treated with DBT could increase lymphocyte numbers in thymus and periphery, and improve thymocyte subpopulations, resulting in enhancement in immune function. Conclusion DBT can enhance the immunological reconstitution of BMT mice.

Objective: To report a case of azoospermia with a karyotype of 45,X,der(Y)t(Y;13)(q11.2;q12),-13,accompanied with slight bilateral gynecomastia and multiple nodules.Methods: The karyotype was identified by karyotyping and FISH,and the breakpoints of the Y chromosome and the copy number of the BRCA2 gene in 13q12 determined by PCR-STS and DNA polymorphic analysis.The testis and nodule tissues of the patient were obtained for biopsy.Results: FISH confirmed SRY and centromere of the Y chromosome on the questionable 13 chromosome and the karyotype to be 45,X,der(Y)t(Y;13)(q11.1;q12),-13.ish der(Y)(SRY+,DYZ3+,wcp13+).PCR-STS showed the deletion of regions AZFa,b and C,with a breakpoint located inYq11.1 below sY82.No deletion of the BRCA2 gene was observed.The patient was diagnosed with Sertoli cell-only syndrome by testicular biopsy and with angiolipomata by pathological examination of the nodule tissue.Conclusion: The patient's phenotype of complete masculinization could be attributed to presence of the SRY gene,and his azoospermia with small testis to the absence of a fragment from Yq11.1 to Yqter.However,the molecular mechanism of angiolipoma remains unknown.
