Objective This study aims to monitor the mRNA ratio of podocin to nephrin (PNR) in glomerular podocytes of early diabetic kidney disease (DKD) rat models. The feasibility of using PNR as an early diagnostic indicator for DKD was evaluated by comparing it with the urinary albumin-to-creatinine ratio (U-ACR). Additionally, the early intervention effects of valsartan and fosinopril sodium on DKD were compared. Methods The DKD rat model was established by caudal intravenous injection of streptozotocin (STZ) at a dosage of 60 mg/kg. The early changes in PNR and U-ACR were monitored and compared, followed by timely intervention with valsartan and fosinopril sodium. Hematoxylin and eosin staining (HE) was used to observe glomerular structure, while transmission electron microscopy examined the ultrastructure of glomerular podocytes. ResultsPNR reached the critical value(≥1) on day 9 after modeling, earlier than U-ACR, which reached the critical value(≥30 mg/g) on day 15. Intervention with valsartan and fosinopril sodium on day 9 after modeling significantly reduced U-ACR (P < 0.05), with low-dose valsartan showing better results than high-dose (P>0.05), while high-dose fosinopril sodium outperformed low-dose (P>0.05). Both low doses of valsartan and fosinopril sodium significantly reduced PNR (P<0.05), with no significant effect observed for high doses. The interventions with valsartan and fosinopril sodium improved and maintained glomerular structure and podocyte arrangement. ConclusionPNR changes earlier than U-ACR, indicating its potential as an early diagnostic marker for DKD in rats. Early intervention with valsartan and fosinopril sodium demonstrates a therapeutic effect on DKD in rats.

Objective To observe the attenuated and synergistic effect of meteorism tablets in treating HBeAg-positive chronic hepatitis B patients. Methods Eighty patients of HBeAg-positive chronic hepatitis B were randomly divided into treatment group (meteorism tablets combined with telbivudine) and control group (telbivudine), and treated for one year. The changes of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the negative rate of HBV-DNA, the negative rate of HBeAg, HBeAg/HbeAb serological conversion rate, creatine kinase (CK) before and after treatment, and safety were observed. Results After treatment, biochemical response, virological response and HBeAg serological response was more significant in the treatment group than that in the control group (P<0.05). The percetage of patients with elevated CK in the treatment group was significantly lower than that in the control group (32.5% vs 60%, P<0.05). Conclusion Meteorism tablets combined with telbivudine has attenuated and synergistic effect in treating HBeAg-positive chronic hepatitis B patients.

Objective: To explore the clinical value of echocardiography in differential diagnosis of segmental wall motion abnormalities in coronary heart disease(CHD), and to provide help for clinical treatment. Methods: From January 2017 to November 2018, 56 patients with segmental abnormal wall motion of CHD in Yuyao People's Hospital of Zhejiang Province were selected in the study.All patients were diagnosed by echocardiography and coronary angiography.The diagnostic coincidence rate, specificity, sensitivity, false negative rate, false positive rate and accuracy of echocardiography were evaluated.

Conclusion Cardiac echocardiography has a high diagnostic value in differential diagnosis of segmental wall motion abnormalities in CHD.It can guide the clinical treatment of these patients to formulate a reasonable treatment plan.Moreover, it is easy to operate, with low cost and more acceptable to patients.

OBJECTIVE: To compare the clinical efficacy of micro steel plate and Kirschner needle oblique and transverse internal fixation of adjacent metacarpal bone in the treatment of metacarpal diaphyseal oblique fracture. METHODS: Fifty-nine patients with metacarpal diaphyseal oblique fractures admitted between January 2018 and September 2021 were selected as the study subjects and divided into the observation group (29 cases) and the control group (30 cases) based on different internal fixation methods. The observation group was treated with Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones, while the control group was treated with micro steel plate internal fixation. Postoperative complications, operation time, incision length, fracture healing time, treatment cost, and metacarpophalangeal function were compared between the two groups. RESULTS: No incision or Kirschner wire infections occurred in the 59 patients, except for one in the observation group. No fixation loosening, rupture, or loss of fracture reduction occurred in any of the patients. The operation time and incision length in the observation group were (20.5±4.2) min and (1.6±0.2) cm, respectively, which were significantly shorter than those in the control group (30.8±5.6) min and (4.3±0.8) cm (P<0.05). The treatment cost and fracture healing time in the observation group were (3 804.5±300.8) yuan and (7.2±1.1) weeks, respectively, which were significantly lower than those in the control group (9 906.9±860.6) yuan and (9.3±1.7) weeks (P<0.05). The excellent and good rate of metacarpophalangeal joint function in the observation group was significantly higher than that in the control group at 1, 2, and 3 months after operation (P<0.05), but there was no significant difference between the two groups at 6 months after operation (P>0.05). CONCLUSION Micro steel plate internal fixation and Kirschner wire oblique and transverse internal fixation of adjacent metacarpal bones are both viable surgical methods for treating metacarpal diaphyseal oblique fractures. However, the latter has the advantages of causing less surgical trauma, shorter operation time, better fracture healing, lower cost of fixation materials, and no need for secondary incision and removal of internal fixation.

The clinical characteristics of a case of fetal alcohol syndrome (FAS) diagnosed by Shenzhen Children′s Hospital were summarized.The patient was 6 years and 4 months old, and admitted to the hospital because of her " slow growth of height for more than 6 years" . There was a history of alcohol exposure in the fetus.The infant was born with low body mass, and grew slowly in height and body mass after birth.She was diagnosed with FAS due to typical facial features of FAS, microcephalia, poor memory and narrative ability.The effect of alcohol exposure during pregnancy on fetus is permanent, and abstinence is the only way to prevent FAS.In this paper, the clinical characteristics of FAS were summarized and the literature was reviewed in order to improve the clinical understanding of the disease.

OBJECTIVE: To explore gender difference in the clinical manifestations of two children with Keishi-Bukuryo-Gan syndrome (KBGS). METHODS: Clinical manifestations of the two children were reviewed. Genetic testing was carried out through next generation sequencing (NGS). Treatment was summarized, and the prognosis was followed up. RESULTS: Both children showed particular appearance including megatooth, abnormal hair distribution, hands' abnormality and language development delay. NGS revealed that both children have carried pathogenic variants of the ANKRD11 gene (c.1903_1907del and c.4911delT), which resulted in shifting of amino acid sequences starting from the Lysine and Proline at positions 635 and 1638, respectively. The female patient exhibited central precocious puberty. Her height has increased by 13 cm, and sex characteristics has retracted after treatment with leuprorelin for 23 months and recombinant human growth hormone for 1 month. CONCLUSION Comparison of the two cases with different genders and summary of previously reported cases found that male KBGS patients have more obvious dysmorphisms such as triangular face, synophrys, ocular hypertelorism and vertebral body abnormality, with higher morbidity of epilepsy, mental retardation, autism, congenital heart disease, immune thrombocytopenia and other complications. KBGS is an autosomal dominant disease featuring more evident peculiar appearance and global development delay. Male patients often have multi-system involvement, and multidisciplinary cooperation is required for early recognition of particular features in order to improve the prognosis.

Fetal electrocardiogram (ECG) signals provide important clinical information for early diagnosis and intervention of fetal abnormalities. In this paper, we propose a new method for fetal ECG signal extraction and analysis. Firstly, an improved fast independent component analysis method and singular value decomposition algorithm are combined to extract high-quality fetal ECG signals and solve the waveform missing problem. Secondly, a novel convolutional neural network model is applied to identify the QRS complex waves of fetal ECG signals and effectively solve the waveform overlap problem. Finally, high quality extraction of fetal ECG signals and intelligent recognition of fetal QRS complex waves are achieved. The method proposed in this paper was validated with the data from the PhysioNet computing in cardiology challenge 2013 database of the Complex Physiological Signals Research Resource Network. The results show that the average sensitivity and positive prediction values of the extraction algorithm are 98.21% and 99.52%, respectively, and the average sensitivity and positive prediction values of the QRS complex waves recognition algorithm are 94.14% and 95.80%, respectively, which are better than those of other research results. In conclusion, the algorithm and model proposed in this paper have some practical significance and may provide a theoretical basis for clinical medical decision making in the future.
