Diabetic nephropathy is one of the microvascular complications of type 2 diabetes mellitus. 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.

The incidence and its growth rate of hypertension are both very high. Its pathology and pathogenesis are complex and unclear,and it does serious harm to human health. Hypertension remains incurable. Chemical medicine has good effect on hypertension,but life-long application and multi-drug combination are required,with significant adverse reactions. Also,complications can′t be effectively alleviated. Traditional Chinese medicine (TCM)guided by traditional theories,can lower blood pressure,improve metabolic abnormalities and reduce complications. Its advantages or potentials have not been fully exploited and clinical application is inadequate. Metabolic hypertension has become the main form of hypertension,and its formation mechanism is mainly related to metabolic abnormalities and insulin resistance,metabolic inflammation and other pathology and pathogenesis. A better understanding of the current status of antihypertensive pharmacology of TCM,especially devel?opment and application of metabolic hypertension models is of great significance for TCM treatment of hypertension,and for exploration of new approaches to hypertension.

Objective To explore the clinical significance of human papillomavirus L1 capsid protein detection in cervical exfoliated cells in high-risk HPV positive women. Methods From November 2012 to June 2013,386 high-risk HPV positive (detected by hybrid capture Ⅱ) cases were enrolled as eligible women from Huzhou Maternity&Child Care Hospital and Women′s Hospital,School of Medicine, Zhejiang University. All eligible women underwent liquid-based cytology (ThinPrep) followed by colposcopy. Biopsies were taken if indicated. Cervical exfoliated cells were collected for HPV L1 capsid protein detection by immunocytochemistry. Expression of HPV L1 capsid protein in groups with different histological diagnosis were compared, and the role of HPV L1 capsid protein detection in cervical exfoliated cells in cervical lesions screening was accessed. Results Total 386 enrolled eligible women were finally diagnosed histologically as follwed:162 normal cervix, 94 low-grade squamous intraepithelial lesion (LSIL), 128 high-grade squamous intraepithelial lesion (HSIL) and 2 squamous cervical cancer (SCC). The positive expression rate of HPV L1 in HSIL+(HSIL or worse) group was significantly lower than that in LSIL-(LSIL or better) group (19.2% vs 66.4%,P=0.000). While identifying HSIL+ in HPV positive cases and compared with cytology, HPV L1 detection resulted in significant higher sensitivity (80.77%vs 50.77%,P=0.000) and negative predictive value (NPV;87.18% vs 76.47%,P=0.004), significant lower specificity (66.41% vs 81.25%,P=0.000),and comparable positive predictive value (PPV;54.97% vs 57.89%, P=0.619). To identify HSIL+in HPV-positive/cytology-negative women, the sensitivity, specificity, PPV, and NPV of HPV L1 detection were 87.50%, 61.54%, 41.18%, and 94.12%respectively, while 80.00%, 86.36%, 80.00%and 86.36%respectively in HPV-positive/atypical squamous cell of undetermined significance(ASCUS)women. Conclusions HPV L1 capsid detection in cervical exfoliated cells have a role in cervical lesions screening in high-risk HPV positive women, and may be a promising triage for high-risk HPV-positive/cytology-negative or ASCUS women.

Kawasaki disease is generally diagnosed base on its clinical features. Sometimes unusual or atypical presentations make the diagnosis of Kawasaki disease difficult. We experienced an unusual case of Kawasaki disease presented with unilateral parotitis in a 23-month old girl. Despite of intravenous antibiotics treatment, fever and unilateral parotid swelling persisted. Skin rashes, conjunctival injections, and coronary abnormalities showed up on the 8th day of fever. After the intravenous immunoglobulin and salicylates treatment, all symptoms disappeared. Although unilateral parotitis is very unusual presentation of Kawasaki disease, in case of no response to antibiotics, Kawasaki disease should be included in the differential diagnosis.

Objective To assess the effect of neutrophil?to?lymphocyte ratio ( NLR) on the recurrence rate of patients with alpha?fetoprotein (AFP) ?negative hepatocellular carcinoma (HCC) and the value of NLR in predicting prognosis. Methods The clinical data of seventy?seven patients diagnosed with AFP?negative HCC and treated with hepatocellular carcinoma surgery in the First Hospital in Weinan from June 2015 to March 2017 were analyzed. According to the recurrence at the end of the follow?up, the patients were divided into the recurrence group and the non?recurrence group. Cox single factor analysis was used to analyze the relationship between the clinicopathological features and postoperative recurrence, and the clinical risk factors with statistically significance in the univariate analysis were placed in the Cox multivariate regression analysis to determine whether it is independent risk factor. Results The differences between the two groups in the number of tumors (31/15,28/3),tumor size (>5 cm) (5. 53±1. 83,4. 65±1. 73),portal vein tumor thrombus (18/28,2/29),microvascular invasion (14/32,2/29) were all statistically significant (P<0. 05). Cox univariate analysis showed that preoperative NLR levels ( RR=1. 125, 95%CI 1. 052-1. 203, P=0. 029 ) , tumor number ( RR=0. 943,95%CI 1. 007-1. 330, P=0. 019 ) , tumor size (>5 cm ) ( RR=0. 550, 95%CI 0. 316-0. 956, P=0. 038),portal vein tumor thrombus (RR=1. 294,95%CI 1. 208-1. 386,P=0. 022),microvascular invasion (RR=1. 575,95%CI1. 209-2. 052,P=0. 028) were the risk factors of postoperative recurrence. Cox regression model showed that tumor number (RR=1. 830,95%CI 1. 184-2. 828,P=0. 026),portal vein tumor thrombus ( RR=2. 860,95%CI 2. 062-3. 968,P=0. 001) ,microvascular invasion ( RR=1. 760,95%CI 1. 019-3. 041,P=0. 037) and preoperative NLR level ( RR=1. 890,95%CI 1. 056-3. 383,P=0. 028) were independent risk factors of the recurrence in AFP negative HCC patients after surgery. Among the 77 patients,46 cases were in the recurrent group, the average value of NLR was 3. 49 ± 0. 30, and the average preoperative NLR of the non?recurrence group ( 31 patients ) were 3. 01 ± 0. 30, the difference between the two groups in NLR value was statistically significant (t=-6. 885,P=0. 000). According to the ROC curve,the NLR=3. 17 corresponded to the maximum Youden index,the sensitivity of NLR was 82. 6%,the specificity was 67. 7%. Conclusion The preoperative NLR level is inversely proportional to the recurrence?free survival time of patients with AFP?negative HCC,which is one of the independent risk factors for recurrence. The optimal critical value of NLR is 3. 17.
