Objective To investigate the clinical value of high-frequency ultrasound in the diagnosis of pronator teres syndrome (PTS). Methods The high-frequency ultrasound was employed to examine and measure the median nerve of the pronator teres muscle in 30 patients with PTS and 30 healthy volunteers (control group).The long-axis diameter (LA),short-axis diameter (SA) and cross-sectional area (CSA) of the median nerve were measured.The receiver operating characteristic curve of the median nerve ultrasonic measurement results was established,and the area under the curve (AUC) was calculated.The diagnostic efficiency of each index for PTS was compared with the surgical results as a reference. Results The PTS group showed larger LA[(5.02±0.50) mm vs.(3.89±0.41) mm;t=4.38,P=0.013],SA[(2.55±0.46) mm vs.(1.70±0.41) mm;t=5.19,P=0.009],and CSA[(11.13±3.72) mm² vs.(6.88±2.68) mm²;t=8.42,P=0.008] of the median nerve than the control group.The AUC of CSA,SA,and LA was 94.3% (95%CI=0.912-0.972,Z=3.586,P=0.001),77.7% (95%CI=0.734-0.815,Z=2.855, P=0.006),and 78.8% (95%CI=0.752-0.821,Z=3.091,P=0.004),respectively.With 8.63 mm² as the cutoff value,the sensitivity and specificity of CSA in diagnosing PTS were 93.3% and 90.0%,respectively. Conclusion High-frequency ultrasound is a practical method for diagnosing PTS,and the CSA of median nerve has a high diagnostic value.

Experimental research on male infertility is critical to the study of the pathogenesis of male infertility and the evaluation of drug therapy. This paper reviewed animal experiments on male infertility in recent years. The experimental models of male infertility mainly include oligoasthenozoospermia （OA），teratozoospermia，azoospermia， and varicocele animal models. The OA animal models are mostly induced by glycosides of Tripterygium wilfordii （GTW）， adenine，hydrocortisone， and radiation，which are mainly chemical means. The animal models of azoospermia were usually constructed by intraperitoneal injection of bissulfonyl alkylating agent busulfan and immersion of scrotum in 43 ℃ water. There are few studies on animal models of teratozoospermia，and the induction methods by GTW and methyl methanesulfonate（MMS） are common. The animal models of varicocele-caused infertility are usually induced by operation. The ligation of the middle division of the left renal vein between the lateral inferior vena cava and the medial spermatic vein has a significant influence on testicular morphology and epididymal sperm quality. Animal experimental studies have shown that classic prescriptions for tonifying the kidney and promoting spermatogenesis represented by Wuzi Yanzongwan and clinical empirical prescriptions by modern research have played a significant role in the treatment of male infertility. The mechanism of tonifying the kidney in the treatment of male infertility mainly focuses on inhibiting spermatogenic cell apoptosis. The kidney-tonifying method can regulate the apoptosis of spermatogenic cells，which provides a new treatment idea and a reliable scientific basis for traditional Chinese medicine in the field of male reproduction.

Objective:To explore the effect of applying SHOW mode of mindfulness meditation training in the psychological intervention of patients with advanced lung cancer.Methods:From June 2020 to May 2021, a total of 130 patients with advanced lung cancer who were hospitalized in Taizhou Central Hospital were selected as the research objects by the convenient sampling method. According to the random number table method, patients were divided into the study group and the control group, with 65 cases in each group. The control group was given routine mindfulness meditation intervention, while the study group was given SHOW model mindfulness meditation training on the basis of the control group. The degree of anxiety and depression, psychological resilience and self-management efficacy of patients in the two groups were observed before and after intervention.Results:After intervention, scores of Hamilton Anxiety Scale (HAMA-14) and Hamilton Depression Scale (HAMD-17) in the two groups were lower than those before intervention and scores of HAMA-14 and HAMD-17 in the study group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The scores of Connor-Davidson Resilience Scale (CD-RISC) and Strategies Used by People to Promote Health-Chinese (C-SUPPH) in two groups were higher than those before intervention and the scores of CD-RISC and C-SUPPH in the study group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The SHOW model mindfulness meditation training has a good application effect in the psychological intervention of patients with advanced lung cancer, which can effectively improve the degree of anxiety and depression of patients and enhance their psychological resilience and self-management efficacy.

The medicinal and edible Polygonatum cyrtonema is one of the original species of Polygonati Rhizoma. In this study,HPLC fingerprints for 25 batches of P. cyrtonema from 6 provinces were established. A total of 14 common peaks were identified and the similarities of the fingerprints were in the range of 0. 939-0. 999. In additon, the partial least squares-discriminant analysis(PLSDA) demonstrated that the samples had low discriminability except for JX-1 and most components of them had no significant correlation with environmental factors such as longitude, latitude, and altitude. Thus, chemical composition specificity of P. cyrtonema in natural distribution areas had no obvious regularity and their variation might be induced by the local environment. This conclusion explained the lack of records about Dao-di area of Polygonati Rhizoma. However, JX-1 boasted significantly higher content of 5-hydroxymethylfurfural(HMF) and 4',5,7-trihydroxy-6,8-dimethylhomoisoflavone( HIF), thick and long inflorescence and rhizome, and extremely high yield. Therefore, excellent variety of P. cyrtonema might have great potential to improve the quality and yield of Polygonati Rhizoma. Moreover, three components of HMF, polygonalline A(PA), and HIF were identified in the fingerprint. Among them, HMF has the activities of blood rheology improvement, antioxidation, and anti-myocardial ischemia and PA is an indolizine alkaloid with potential anti-inflammatory activity. HIF, the characteristic homoisoflavone in Polygonatum, has the pharmacological activities of regulating blood glucose and anti-tumor. A quantitative analysis method can provide a theoretical basis for the improvement of the quality evaluation of Polygonati Rhizoma.

Objective: To investigate the expression level of antisense transcript of pseudogene, general transcription factor Ⅱi psedugen23 (GTF2IP23), in breast cancer and its effect on the host gene general transcription factor Ⅱi (GTF2I). Methods: The expressions of GTF2IP23 and GTF2I were detected in 40 cases of invasive breast cancer tumors and their counterparts by using quantitative real-time polymerase chain reaction (qRT-PCR). The effects of GTF2IP23 on the expression of GTF2I gene and cell proliferation and migration were analyzed by overexpression of GTF2IP23 in breast cancer cells. Results: The expression of GTF2IP23 mRNA in breast cancer tissues was significantly higher than that in adjacent tissues (P<0.001), while the expression of GTF2I mRNA was significantly lower than that in adjacent tissues (P=0.007). The expression of GTF2IP23 was negatively correlated with GTF2I (r=-0.335, P=0.025). The expression of GTF2IP23 in breast cancer cells was significantly higher than in normal breast cells (P<0.01), while GTF2I expression in breast cancer cells was significantly lower than that in normal breast cells (P<0.01). Overexpression of GTF2IP23 in ZR-75-30 cells significantly reduced the expression of GTF2I (P=0.034) and enhanced cell proliferation (P=0.017) and migration (P=0.026) capacity. Conclusions GTF2IP23 is distinctly upregulated in breast cancer, it inhibits the expression of real gene GTF2I and promotes the proliferation of breast cancer cells.

OBJECTIVETo explore clinical features and mutation types in patients from Fujian area with glutaric academia type I(GA I).

METHODSSerum acylcarnitine and urine organic acid of 3 patients were determined with tandem mass spectrometry and gas chromatographic mass spectrometry. The patients also underwent magnetic resonance imaging analysis for the cranial region. Genomic DNA was extracted from peripheral blood samples, and the 12 exons and flanking regions of the GCDH gene were amplified with PCR and subjected to direct DNA sequencing. One hundred healthy newborns were used as controls.

RESULTSMutations of the GCDH gene were identified in all of the 3 patients. Two patients have carried compound heterozygous mutations including c.1244-2A>C and c.1147C>T(p.R383C), c.406G>T(p.G136C) and c.1169G>A(p.G390E), respectively. One has carried homozygous c.1244-2A>C mutation. The same mutations were not detected among the 100 healthy newborns. Only one patient received early intervention and did not develop the disease. The other two had irreversible damagesto their intelligence.

CONCLUSIONc.1169G>A(p.G390E) is likely pathogenic mutations for GA I patients from Fujianarea. Early screening of neonatal metabolic diseases is crucial for such patients.
