Recently, the modern medical researches and treatments of diabetic nephropathy have some progress, but the treatment delaying the progress of renal function is still unknown. Many clinical practices showed that the traditional Chinese medicine on this disease was effective. Thus, this paper was to summarize the traditional Chinese medicine view of etiology and pathogenesis, clinical researches, experimental researches in order provide reference for clinical treatment.

Objective To detect a novel mutation in SCN4A gene related to normokalemic periodic paralysis (normoPP) in one Chinese family.Methods Genomic DNA of two patients and their relatives in this family was extracted from peripheral blood leukocytes and amplified by polymerase chain reaction (PCR). All 24 exons of SCN4A gene were screened with denaturing high performance liquid chromatography (DHPLC) technology,and then sequence analysis of those DHPLC chromatograms showing heteroduplex were compared with the unaffected controls.Results Routine laboratory tests were carried on within normal ranges with the exception of an elevated creatine kinase (1126 U/L,normal

Recently, traditional Chinese medicine (TCM) researches on diabetic peripheral neuropathy made great progress. It is found that theetiology and pathogenesis was the deficiency in origin and the ecessive in superficialty. The deficiencyincluded Yin deficiency, Qi deficiency, blood deficiency, deficiency of both Qi and Yin, Yang deficiency, while the ecessive in superficialty included blood stasis, stasis of phlegm and blood. Thus, the principles of treatment were supplementing Qi and nourishing Yin, warming Yang, promoting blood and removing blood stasis, and smooth Luo, all of which showed the characteristics of TCM treatment were combination of inside and outside, and multi-target effects. This paper reviewed the progress of clinical and experimental studies on the TCM for diabetic peripheral neuropathy.

Objective To study the clinical features of hyperkalemic periodic paralysis (hyperKPP) and the relationship with SCN4A gene in a Chinese family Methods The clinical features of 7 patients in a Chinese family with hyperKPP were summarized All 24 exons of SCN4A gene were screened with denaturing high performance liquid chromatography (DHPLC) technology, and then sequence analysis was performed on those with abnormal elution peak Results This family showed typical clinical features of hyperKPP but without myotonia Three mutations were found in exon 13, 23 and 24 respectively Linkage analysis and direct sequencing showed the mutation in exon 24 was a synonymous mutation The mutation in exon 23 was a missense mutation, but proved to be a benign polimophism; the mutation in exon 13 was proved leading to the best known amino acid exchange Thr704Met Conclusion SCN4A gene should be related to hyperKPP, and Thr704Met be responsible for hyperKPP in this Chinese family

Objective:To compare the effect of fluorescence staining and periodic acid-Schiff staining in the diagnosis of fungal keratitis (FK).Methods:A total of 147 corneal specimens from 147 FK patients treated in Eye Hospital of Shandong First Medical University from January 2017 to May 2019 with positive corneal scraping or fungal culture were collected.Among them, there were 84 cases with penetrating keratoplasty (PKP), 42 cases with lamellar keratoplasty (LKP) and 21 cases with lesion resection.Another 11 cases with herpes simplex virus keratitis served as negative control.The corneal tissue specimens were performed with fungal fluorescence staining and periodic acid-Schiff staining, respectively.The stained sections were placed under fluorescence microscope and optical microscope to observe fungal hyphae or spores, respectively.The positive rates of the two staining methods were compared, and the positive cases of the diagnosis of FK in corneal tissue samples obtained by different surgical methods and corneal infection caused by different strains of the two staining methods were compared.Written informed consent was obtained from each patient.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Shandong Eye Hospital (No.SDSYKYY-2016012).Results:The positive rate of periodic acid-Schiff staining and fungal fluorescence staining was 60.5% (89/147) and 79.6% (117/147), respectively.The positive rate of fluorescence staining in the diagnosis of fungal keratitis was significantly higher than that of periodic acid-Schiff staining ( χ2=28.00, P<0.01), and both the specificity of the two staining methods was 100%.The positive rate of specimens obtained by PKP with fluorescent staining was 85.7% (72/84), and the positive rate with periodic acid-Schiff staining was 65.5% (55/84), and the difference was statistically significant ( χ2=17.00, P<0.01). The positive rate of specimens obtained by LKP with fluorescent staining was 71.4% (30/42), and the positive rate with periodic acid-Schiff staining was 52.4% (22/42), and the difference was statistically significant ( χ2=8.00, P<0.01). The positive rate of resected foci specimens with fluorescent staining was 71.4% (15/21), and the positive rate with periodic acid-Schiff staining was 57.1% (12/21), and the difference was not statistically significant ( χ2=1.30, P=0.25). The positive cases of two kinds of staining were different among different fungal strains.Among them, the positive cases of Fusarium solani complex, Pythium insidiosum, Aspergillus fumigatus complex, Candida guilliermondii, Trichoderma and Nigrograna mackinnonii with fluorescence staining were 19, 5, 5, 1, 1 and 1, and the positive cases of periodic acid-Schiff staining were 11, 0, 3, 0, 0 and 0, respectively.The staining results of the 11 negative controls were negative. Conclusions:Fluorescence staining is more sensitive than periodic acid-Schiff staining in the detection of fungal components in paraffin-embedded corneal tissues, and it can significantly improve the fungal detection rates.

Objective To observe the effect of Qingrequzhuo capsule on blood pressure of patients with type 2 diabetes metabolism syndrome. Methods 72 cases with type 2 diabetes and metabolic syndrome were randomly recruited into a control group and a treatment group. Based on the conventional treatment, the treatment group was treated with Qingrequzhuo capsule, 5 tablets/time, 3 times/d; While the control group was treated with ramipril tablets 2.5 mg, 1 times/d, respectively. After 3 months, the value of blood pressure and blood lipids were observed. Results After treatment, the blood pressure and blood lipid were significantly improved in both groups(P<0.05), but no significant difference between the two groups (P>0.05). Conclusion Besides improving blood lipids, Qingrequzhuo capsule can also reduce high blood pressure and improve a variety of risk factors to cardiovascular disease.

Type 2 diabetes macrovascular disease is the main cause of death in type 2 diabetes mellitus. In recent years, the modern medical research and treatment of type 2 diabetes macrovascular disease has made some progress, but the international clinical trials suggest that the current treatment can not effectively reduce the incidence of this disease. Many clinical practices show that the effect of traditional Chinese medicine on this disease is exact, so that the clinical workers on the treatment of type 2 diabetes mellitus macrovascular disease of the status quo, now from the etiology and pathogenesis,clinical research, experimental research on the literature published in recent years, to provide reference for clinical treatment.
