OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Objective To explore the diagnostic value of virtual touch tissue quantification (VTQ) for the assessment of liver fibrosis in patients with chronic hepatitis B.Methods VTQ was prospectively performed in 181 patients with chronic hepatitis B and a shear wave velocity (Vs) indirectly reflecting liver stiffness was obtained for each patient.With the gold standards of fibrotic stages and inflammation grades,the relationship between Vs,fibrotic stages and inflammation grades was evaluated.Results A relatively high correlation existed between Vs and liver fibrotic stages (r ＝ 0.812,P ＜ 0.001).Significant differences existed among groups with different fibrotic stages except for groups SO vs.S1 and S1 vs.S2 (P ＜ 0.05).The areas under the ROC curve were 0.971,0.96l,0.969 and 0.908 for Vs predicting S≥S1,S≥S2,S≥S3 and S =S4 fibrosis respectively.Moderate correlation existed between Vs and inflammation grades (r =0.476,P =0.000).Conclusion Capable of staging liver fibrosis and preliminarily grading inflammation,VTQ is helpful for the early diagnosis of liver fibrosis and assessment of therapeutic follow-up and prognosis in patients with chronic hepatitis B.

Objective To evaluate the clinical values of acoustic radiation force impulse(ARFI) elastography for liver fibrosis on hepatopath patients.Methods ARFI elastography was prospectively performed on 99 patients prepared to undergo hepatic surgery to get a shear wave velocity(Vs) which was the representative of liver stiffness.The fibrosis stages,inflammation grades and steatosis grades were evaluated histologically after surgery.Values of Vs were compared with the histological results.Results Values of Vs with fibrosis stage 0-4 was (1.14 ± 0.22) m/s,(1.30 ± 0.22) m/s,(1.36 ± 0.38) m/s,(1.47 ± 0.37)m/s and (1.87 ± 0.08) m/s,respectively.A significant difference was observed among them (P ＜0.001).There was a certain correlation between Vs and fibrosis stage(r =0.541,P ＜0.001).Vs was a significant predictor of stage ≥3 fibrosis with an area under the ROC curve of 0.812,sensitivity 73.2％ and specificity 81.4％ when 1.40 m/s was the cutoff value (P ＜ 0.001).Values of Vs with inflammation grade 0-3 was (1.17 ± 0.16)m/s,(1.43 ± 0.36) m/s,(1.59 ± 0.53) m/s and (1.89 ± 0.59) m/s,respectively,which were significantly different (P ＜ 0.001).A certain correlation was observed between Vs and inflammation grade(r =0.383,P ＜0.001).Values of Vs with steatosis grade 0-4 was (1.61 ±0.42) m/s,(1.47±0.58) m/s,(1.56 ± 0.71)m/s,1.13 m/s and (0.94 ± 0.95) m/s.Obvious difference didn't exist between Vs and steatosis grade (P =0.286).Obvious correlation wasn't observed between them,either (r =-0.177,P =0.080).Conclusions ARFI elastography has a certain value for the evaluation of liver fibrosis,while inflammation grade may affect its performance.

Limit test of flavones in diterpene ginkgolides meglumine injection materials by UV-Vis and HPLC-DAD method was studied in this essay. The HPLC-DAD method has lower LOD (about 1% of the UV-Vis), that is, the sensitivity is higher than UV-Vis method. Through the analysis of the kinds of flavonoids ingredients in the samples by LC-MS, the three compounds with highest contents are kaempferol, quercetin and isorhamnetin. Kaempferol, quercetin and isorhamnetin were chosen as reference compounds for HPLC analysis, and the HPLC separation analysis was carried on an Agilent Eclipse plus C18 column (4.6 mm x 250 mm, 5 μm) with methanol and water containing 0.4% phosphoric acid (50: 50) as mobile phase, and the flow rate was 1.0 mL x min(-1). The detection wavelength was set at 360 nm. This method has good specificity, precision and reproducibility. The LODs of quercetin, kaempferide and isorhamnetin were 27.6, 22.3, 29.5 μg x L(-1). The average recovery was 87.9% (RSD 3.3%), 91.7% (RSD 3.1%), 88.3 (RSD 1.3%) for quercetin, kaempferide and isorhamnetin, respectively. Based on the 10 batches of sample results and sensitivity of different HPLC, the content of total flavonoids ingredients of diterpene ginkgolides meglumine injection materials was limited no more than 2 x 10(-5). This method is simple, quick and has good maneuverability, and could be used to the limit test of flavonoids in the diterpene ginkgolides meglumine injection materials.

Objective To investigate the approach and safety of minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi. Methods Clinical data of 21 cases with symptomatic caliceal diverticular calculi were retrospectively reviewed. Twelve females and 9 males aged 22 to 57 years old. The average diameter of caliceal diverticulum was 3.7 cm (2.5-7.0 cm) and average diameter of calculi was 2.3 cm (0.8-3.5 cm). The patients underwent flexible ureteroscopic lithotripsy, PCNL or mPCNL, laparoscopic techniques and laparoscopy-assisted transperitoneal PCNL, respectively. Four cases underwent flexible ureteroscopic lithotripsy. PCNL (2 cases) or mPCNL(5 cases)were performed in 7 cases. Nine cases underwent laparoscopic techniques. Laparoscopyassisted transperitoneal PCNL was performed in 1 case. Results The operations were performed successfully in 21 cases. No case need to transfer to open surgery during the operation and no major complications like perforation or organic injury were noted. One case with iatrogenic arteriovenous fistula of the kidney after 1 week postoperative was cured by delayed hemorrhage 2 days later, while clinical symptoms of 2 cases with residue calculi relieved. 19 cases without residue calculi were followed up for 6 to 12 month without recurrence. Conclusions After handling indication of treatment efficiently and creating advisable therapeutic decision-making, minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi appears to be effective and safe.

Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device(PLFT) in high risk patients with benign prostate hyperplasia (BPH). Methods Sixty-six high risk patients diagnosed with BPH, including aged ≥80 in 32 pa-tients, hypertension in 31 patients, diabetes in 5 patients, heart failure in 8 patients, chronic obstruc-tive pulmonary disease in 8 patients, cerebral infarction in 11 patients, fracture, amputation or joint stiffness unsuitable for lithotomy position in 3 patients, abnormal blood coagulation in 4 patients, pan-creatitis in 2 patients, cardiac arrhythmia in 6 patients and malignant tumor in 3 patients, were treated with PLFT using individual power at urethral local anesthesia, resulting in coagulation necrosis in 15%-30% of prostate tissue around urethra. Meanwhile, real-time monitoring the temperature of prostate and the tissue around it was used. All patients were evaluated by comparing volume of pros-tate, maximal urinary flow (Q_max), international prostate symptom score (IPSS) and quality of life questionnaire (QOL) in pre-treatment and three months after respectively. Results All of patients well tolerated PLFT. There was bleeding lightly, infection lightly and temporary incontinence. There was no severe surgical complication. After three months, the volume of prostate reduced from 62. 2 ml to 44.5 ml; IPSS decreased from 23. 4 to 11.7; QOL decreased from 4.5 to 2.4; Q_max rised from 4, 2 ml/s to 11.2 ml/s. All differences reached significance. Conclusion PLFT is one of effective and safe treatments for patients with BPH especial BPH complicating with severe conditions.

Yunnan sudden death syndrome (YSDS) is an abruptly fatal disease of unknown etiology, found mostly in central or northwestern mountain area (with altitude between 1,815 and 2,225 meters) of Yunnan province from June to September every year. It occurs mostly in young female adults, with high incidences in Lisu, Yi and Miao ethnics and high familial aggregation. The clinical manifestation of YSDS is changeful and the pathological characteristic is lack of specificity. The pathogenesis may be attributed to several factors including poor hygiene and lower socioeconomic conditions, lack of Selenium or Chromium, infection of Coxsackie B virus, mushroom consumption and special geological conditions. This article reviews the epidemiologic features, clinical manifestations, pathological features, etiology and hypothesis in order to provide clues for the research of YSDS.

OBJECTIVE: To explore the forensic pathological features of death caused by anaphylactic shock. METHODS: One hundred and forty-two death cases of anaphylactic shock were retrospectively analyzed. The IgE level in the serum of anaphylactic shock cases were statistically compared with that of 62 non-anaphylactic shock cases. RESULTS: Most cases (77.46%) of anaphylactic shock death occurred in the medical institutes, with intravenous drug administration accounting for 53.53% of anaphylactic shock death. β-Lactam antibiotics, glucocorticoid and herbal medications were responsible for a significant proportion of such cases. Although characteristic histopathological changes were absent in vast majority of these anaphylactic shock cases, the differences of IgE levels in the serum between anaphylactic shock group and non-anaphylactic shock group were statistically significant (P<0.05). CONCLUSION Combined information including clinical data, autopsy results, IgE level, and other specific test results should be evaluated together in the forensic pathological diagnosis of anaphylactic shock.
