?AlM:To observe the eye complications in the cases of acute chlorine gas poisoning.
?METHODS:A retrospective review of 121 cases of acute chlorine gas poising with eye irritation, dry eye and other eye complications in Linyi People’s Hospital from February 2009 to February 2013 was performed.
?RESULTS: Among 121 patients, 117 cases ( about 96. 7%) had complications of eye irritation and conjunctival and corneal epithelial damage, and the ocular surface damage was aggravated with the increasing level of chlorine gas poisoning. After 3, 6mo being discharged, 32 and 7 patients respectively occurred dry eye among 115 patients followed up. One mild chlorine poisoning patient, during the hormonotherapy of pulmonary complication, complicated with bullous retinal detachment, of which symptoms and physical signs had been improved after stopping hormonotherapy and adding drugs facilitating fluid absorption. One severe chlorine poisoning patient with loss of consciousness during the treatment, had corneal ulcer and after ulcer being healed with drug and conjunctival flap covering surgery, was left permanent leukoma cornea.
?CONCLUSlON: Acute chlorine poisoning can cause corneal and conjunctival epithelial damage and dry eye. Ocular complications like bullous retinal detachment associated with hormone application should be paid more attention to in the hormonotherapy. For some patients with severe poisoning, the therapy of corneal and conjunctival epitheliums should be taken seriously in case of irreparable damage in rescuing patient’s life.

Background and purpose:The incidence of liver cancer is high in China. Primary liver cancers usually occur in patients with liver cirrhosis, which is a challenge for the early diagnosis of liver cancer. Our purpose is to investigate the efifcacy of contrast-enhanced ultrasonography (CEUS) in the early identiifcation and diagnosis of small hepatocellular carcinoma (HCC) by regularly tracking and supervising the high risk population. Methods:A total of 320 high risk patients of HCC admitted in our hospital from February 2011 to November 2013 were enrolled in this prospective study. All patients underwent conventional ultrasound and hepatic CEUS. The differential diagnosis of malignant HCCs from benign ones was based on the enhancement patterns of hepatic lesions in different phases on CEUS. Results:Twenty patients were diagnosed as small HCC among 320 HCC high risk patients who were under regular surveillance using CEUS and all were pathologically conifrmed. Seven of the 20 HCC cases were smaller than 1.0 cm and 13 measured 1.1-2.0 cm. There were 6 (30.0%) HCCs presented as“early wash-in and slow wash-out”atypical pattern of HCC. The small size of the lesion and iso-echogenicity were the main factors of atypical pattern of HCC on CEUS.Conclusion:Ultrasonography and CEUS surveillance is a useful strategy for the early detection of small HCCs in high risk patients, which can help them to receive proper therapeutic management in time.

1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to evaluate the quality of 21 Farfarae Flos (FF) samples from different growth regions. Principal component analysis showed that wild and cultivated FF could be separated clearly, suggesting a big chemical difference existed between them. Supervised PLS-DA analysis indicated that the wild samples showed higher levels of secondary metabolites, such as bauer-7-ene-3β, 16α-diol, chlorogenic acid, rutin, 7-(3'-ethylcrotonoyloxy)-1α-(2'-methyl-butyryloxy)-3, 14-dehydro-Z-notonipetranone (EMDNT), tussilagone, β-sitosterol and sitosterone. This is consistent with traditional experience that the quality of wild samples are better than that of cultivated ones. The content of pyrrolizidine alkaloids senkirkine also differed greatly among samples from different habitats. The Pearson correlation analysis showed that senkirkine is positively correlated with 4, 5-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid, 3,4-O-dicaffeoylquinic acid, rutin, kampferol analogues, to a statistically significant extent. The correlation between the toxic compounds and the bioactive components in FF should be further studied.

Chinese Journal of Integrated Traditional and Western Medicine 2002;22(7):494-495
OBJECTIVETo explore the memory quotient and hormone level in women with perimenopausal syndrome and healthy women in perimenopausal period, and the effect of estrogen and Chinese nourishing Kidney herbs (CNKH) on memory.
METHODSFifty-six women of perimenopausal syndrome were treated with estrogen (n = 24) and CNKH (n = 32) respectively. The changes of memory and estrogen level before and after treatment were determined and compared with those in healthy women.
RESULTSThe memory quotient (MQ) and estrogen level increased and follicule-stimulating hormone (FSH) level decreased significantly after treatment in both groups (P < 0.01), these parameters approached to those in healthy women. The difference of therapeutic effect between the two treated group was insignificant (P > 0.05).
CONCLUSIONThe decrease of memory is related to the lowering of estrogen level, CNKH could improve the brain function and enhance memory.

OBJECTIVETo observe the changes of the mechanical pain threshold in the rat model of autoimmune prostatitis, explore the mechanism of autoimmune prostatitis pain and offer some animal experimental evidence for the drug therapy of the condition.
METHODSTwenty male Wistar rats weighing 180 - 220 g were divided into a model and a control group. The autoimmune prostatitis model was established by subcutaneous injection of an extract of male rat prostate glands (RPG) at 60 mg/ml in Freund's complete adjuvant (FCA) and pertussis-diphtheria-tetanus vaccine at 0 and 30 days, respectively. Mechanical tactile hyperalgesia was measured once a week using Von Frey Filaments from the beginning of the study. At 8 weeks after modeling, the rats were sacrificed and the prostate tissues harvested for observation of histomorphological changes by HE staining.
RESULTSHE staining revealed different degrees of benign prostatitis in the model rats. Compared with the controls, the mechanical pain threshold in the model rats was significantly decreased with the increased time of modeling, from (65.52 +/- 6.27) g at 0 week to (23.67 +/- 4.09) g at 8 weeks (P < 0.01). Statistically significant differences were found in the variation trend at different time points between the two groups (P < 0.01).
CONCLUSIONAutoimmune prostatitis models were successfully established in rats and hyperalgesia was induced after modeling.
