The expression of angiopoietin-1 (Ang-1) and thrombospondin-1 (TSP-1) in 5/6 subtotal nephrectomy (STN) rats model, and its correlation to the renal microvasculature injury were investigated. Rat 5/6 STN model was established in adult male SD rats, and the sham-operated group and 5/6 STN group were set up. The renal function and histopathological changes were examined at the 1st, 2nd, 4th, 8th and 12th week after operation. The expression of Ang-1, TSP-1 and CD31 in renal tissues was detected by using immunohistochemistry. From 2nd to 8th week after operation, Ang-1 was significantly expressed in glomeruli of rats with STN. Ang-1 staining in glomeruli of STN group was increased significantly as compared with that in sham-operated group at 4th and 8th week after operation, and subsequently decreased after the 12th week. The expression of TSP-1 was increased significantly in STN group. As compared with sham-operated group, the CD31 expression was significantly down-regulated from the 2nd week. The expression of Ang-1 mRNA was detected by using RT-PCR at the same time points. The expression of Ang-1 mRNA in renal tissue of rats with STN was significantly up-regulated at the 2nd, 4th and 8th week after operation as compared with that in STN group at other time points or in sham-operated group at the same time points, while decreased evidently at the 12th week as compared with that in sham-operated group. It is concluded that there are changes in the mRNA expression of Ang-1, and the significant up-regulation of the expression of TSP-1 in renal tissue of rats with STN, which may be involved in the remnant renal microvasculature injury.

Objective To summarize the diagnosis and treatment experiences of focal nodular hyperplasia (FNH).Methods The clinical data of 48 patients with FNH who were admitted to the Xiangya Hospital from February 2010 to August 2014 were retrospectively analyzed.All the patients received complete serologic tests,abdomen B ultrasound,computed tomography (CT) and magnetic resonance imaging (MRI) examinations.The pathological examinations were done on the patients undergoing surgical treatment.The surgical treatment was done on the unconfirmed FNH patients according to location of space-occupying lesions.The conservative treatment was done on the confirmed FNH patients without clinical symptoms.All the patients were followed up via outpatient examination and telephone interview up to September 2014,and the follow-up included the history review,clinical symptoms and medical examinations.Results Forty-seven patients had normal liver function and 1 had high level of total bilirubin (TBil).The serum tumor markers including AFP,CEA and CA19-9 in all the patients were negative.Fifty-five foci were detected by imaging examination,41 foci were single mass and 7 foci were multifocality.Forty-eight patients were definitively unconfirmed with FNH by B ultrasound.The results of CT examinations in 38 patients showed as follows:low density was in 31 patients and isodensity in 7 patients,including striped and radiated low density showing in the center of tumor in 20 patients and 3 patients with the confirmed FNH.The results of MRI examinations in 10 patients showed as follows:3 patients were confirmed as with FNH; all the 10 patients showed rather homogeneous enhancement in arterial phase; 5 patients were accompanied with radiated foci in the center of tumor,and showed high signal on T2WI,no enhancement in early arterial phase and enhancement in delayed arterial phase.The central scar showed low signal on T1WI and high signal on T2WI.Two patients were confirmed as with FNH by percutaneous trans-hepatic histopathological examinations.Forty patients without the confirmed FNH underwent surgical treatment,including 31 undergoing open hepatectomy and 9 undergoing laparoscopic hepatectomy.No patients had cirrhosis of liver.During operation,47 foci were detected,16 of which located at the left lobe of liver and 31 of which located at the right lobe of liver.Local tumor resection of liver was carried out on 30 patients,right hemihepatectomy or extended right hepatectomy on 7 patients,left hemihepatectomy on 3 patients and combined treatment of cholecystectomy on 12 patients.The operation time,volume of blood loss and diameter of foci were (78-255) minutes,(80-720) mL and (4.6 ± 1.6) cm (range,1.5-11.5 cm).Forty patients were confirmed as with FNH by pathological examination,and 8 patients were cured by conservative treatment.All the 48 patients were followed up for 21 months (range,1-56 months) and survived well without recurrence and complications.Conclusions The clinical symptoms of FNH are atypical and unobvious.The preoperative enhanced CT and MRI examinations can help improve the diagnosis and differential diagnosis of FNH.The surgical treatment could be performed on the patients with significant clinical symptoms and without definitive diagnosis,and the patients with definitive diagnosis should be treated by conservative treatment with the good prognosis.

In order to evaluate the anti-influenza virus activity of the effective monomer from Folium Isatidis (FI) in vivo, we established mice model with viral pneumonia and divided them into 3 different dose groups, then observed their lung indexes, pulmonary pathological changes, pulmonary virus hemagglitination titers, living time and death rates. The results showed that the monomer could reduce the pulmonary index from 2.64 to 1.93, 1.63 and 1.40 (P<0.01) and decrease the hemagglitination titer from 1.15 to 0.84, 0.70 and 0.59 (P<0.01). In addition,the living time from 5.1d to 6.5d, 8.4d and 8.9d respectively(P<0.01). The high dose (75 mg/kg/d) has the similar effect with 100 mg/kg/d dose of virazole(P>0.05), and more effective than 200 mg/kg/d dose of antiviral liquor (P<0.05).

Objective To investigate the clinical value of the intervertebral disc morphous in patients with thoracolumbar vertebral compression fracture. Methods The MRI, X-ray and CT data of 75 patients with thoracolumbar vertebral compression fracture were retrospectively analyzed. The intervertebral disc damage degree was observed, and its correlation with vertebral fracture degree and endplate damage degree was studied. The vertebral body leading edge height, intervertebral space height and back convex Cobb angle in patients with different intervertebral disc damage degree were measured. Results The intervertebral disc damage degree height was positively correlated with endplate damage degree (P<0.01), and the intervertebral disc damage degree was positively correlated with fracture degree (P<0.01). With the increase of the intervertebral disc damage degree in patients with Ⅰ - Ⅳtype intervertebral disc damage, the vertebral body leading edge height and intervertebral space height gradually became smaller: (0.68 ± 0.05), (0.61 ± 0.03), (0.58 ± 0.03), (0.42 ± 0.05) mm, and (0.31 ± 0.06), (0.29 ± 0.03), (0.24 ± 0.06), (0.22 ± 0.02) mm, and there were statistical differences (P<0.05). There was no statistical difference in back convex Cobb angle in patients with different intervertebral disc damage degree (P>0.05). Conclusions It is more important to observe the morphological changes of the intervertebral disc in patients with thoracolumbar vertebral compression fracture, and the damage degree is closely related with the vertebral fracture degree and endplate damage degree.

Objective　To understand the overall under-reporting of cause of death monitoring in Hainan Province, and to provide a scientific basis for evaluating the data from death registration report and health planning in Hainan. Methods　Multi-stage cluster random sampling was used, all towns/streets in cities and counties of the province were ranked from highest to lowest in terms of crude death rate, divided into high, medium and low levels (the number of each level was basically the same), and one was randomly selected from each level. A total of three towns/streets were used as survey areas, and all households in the area were survey households. Death information of resident population during 2018-2020 was collected and compared with routine surveillance data for the same period. The under-reporting rate was calculated, and comparison between groups was performed by chi-square. Results　A total of 12 583 death cases were investigated from 2018 to 2020, and the average mortality was 621.48/105. 4 809 cases were missed with the total under-reporting rate of 38.22%. The under-reporting rate from 2018 to 2020 were 39.75%, 39.99% and 34.77% (χ2=30.404, P<0.01) respectively. The under-reporting rate in eastern and central and western areas were 30.33%, 30.10% and 60.15% (χ2=931.901, P<0.01) respectively. The negative rate were different in different years old group (χ2=14.834, P<0.05). Of the 4 809 under-reported cases, as many as 93.49% died at home, and the composition of deaths in hospitals was about 10 times higher in the center than in the east and west, and the proportion of those who died in hospital in central areas was about 10 times higher than in eastern and central areas. Conclusions　More than half of the cities and counties in Hainan Province have improved the completeness of cause of death surveillance data. The under-reporting rate in age group <5 years are still high, and regular under-reporting investigations are still needed to strengthen the reporting and management of death information.

OBJECTIVETo explore the effect of Penqiangyan Granule (PG) on the immunity of patients with chronic pelvic inflammatory disease (CPID) of blood stasis and Shen-deficiency syndrome (BSSDS) type.

METHODSSixty patients were randomly assigned to two groups: the treatment group treated with PG and the control group with Penyanjing Granule, 30 cases in each group. The treatment course was 4 weeks for both groups. The clinical efficacy, plasma levels of CD4 and CD8, and the serum levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-2 (IL-2) were measured before and after treatment.

RESULTSAfter treatment, the total effective rate in the treatment group and the control group was 96.7% and 63.3% respectively with significant difference between groups (P < 0.05); in the treatment group the plasma CD4, CD4/CD8 and serum IL-2 increased obviously, while the plasma CD8 and serum TNF-alpha decreased markedly (P < 0.05), all were significantly different with those in the control group (P < 0.05).

CONCLUSIONPG can improve the immune function and alleviate inflammation in CPID patients of BSSDS type.
