Aim To investigate the effects of anti-in-flammation and antioxidation of an amphiphilic curcu-min derivative (Curc-OEG)on CCl4-induced hepatic fibrosis in rats.Methods Rats were randomly divided into four groups:control group,model group,curcumin and Curc-OEG treatment group.All rats except those in control group were given subcuta-neous injection of CCl4 and olive oil mixture,twice a week for 8 weeks.After 4 weeks,rats of control and model group were trea-ted with normal saline intravenously,curcumin group were ad-ministered with curcumin 400 mg.kg -1 .d -1 by gavage and Curc-OEG group were treated with Curc-OEG 1 00 mg.kg -1 .d -1 intra-venously respectively.After 4 weeks treatment,the serum levels of ALT and AST were tested.HE and Sirus staining were used to evaluate the extent of liver inflammation and fibrosis.The mRNA expression levels of proinflammatory cytokines of NF-kB,IL-1 β, IL-6,TNF-α,COX-2 were observed with Real Time PCR.The level of MOD,SOD and GSH in liver of rats were quantified. Results The levels of ALT in control,model,curcumin and Curc-OEG group was (31 .7 ±8.7)U·L -1 ,(383.0 ±75.6) U·L -1 ,(406.3 ±204.7)U·L -1 ,(1 07.0 ±73.7)U·L -1 respectively;that of AST was (1 37.7 ±32.7)U·L -1 ,(585.3 ±36.7)U·L -1 ,(485.0 ±246.5)U·L -1 ,(202.7 ±56.0) U·L -1 respectively,Curc-OEG possessed more hepatoprotective effects than that of curcumin.Liver pathology showed Curc-OEG treatment could significantly alleviate steatosis,reduce inflamma-tion and apparently suppress hepatic fibrogenesis by reducing the thickness of bridging fibrotic septa.Compared with curcumin, Curc-OEG down-regulated mRNA and protein expression levels of NF-kB,IL-1 β,IL-6,TNF-α,COX-2 (P <0.05 ).Moreo-ver,Curc-OEG reduced the level of MOD and increased the lev-els of SOD and GSH.Conclusion Curc-OEG could more sig-nificantly protect the rat liver from CCl4-caused fibrogenesis by anti-inflammatory and antioxidant effect than curcumin.

BACKGROUNDNonselective muscarinic receptor antagonist, atropine, was believed to inhibit myopic progression. The purpose of this study was to determine the efficacy, through topical administration, of the M1-selective muscarinic antagonist pirenzepine in preventing experimentally induced form-deprivation myopia in guinea pigs.
METHODSFifty-three guinea pigs, which underwent monocular deprivation with their eyelids sutured, were divided into 6 groups. Three groups were treated with 1%, 2% or 4% pirenzepine ophthalmic solutions; the fourth group with atropine; the fifth with saline and the last group left untreated. Ocular refraction, in vivo biometric measurements and wet eye weight were collected before and after the experiment. All the eyes were finally enucleated for histopathological examination to evaluate the possible toxic effects on ocular structures.
RESULTSAnimals untreated or treated with saline produced (-2.31+/-1.47) D and (-2.25+/-0.88) D of axial myopia respectively. Those treated with 1% pirenzepine ophthalmic solution produced relative myopia of (-1.63+/-0.48) D, and those under the treatment of 2% and 4% pirenzepine ophthalmic solution only developed a relative myopia of (-0.89+/-0.42) D and (-0.70+/-0.41) D (F=9.56, P<0.05). The significant reduction in myopia in 2% and 4% pirenzepine treated animals was caused by significantly less vitreous chamber elongation and axial elongation of the deprived eyes [2% group: (0.009+/-0.052) mm, 4% group: (0.006+/-0.078) mm] when compared with untreated, saline treated or 1% pirenzepine treated guinea pigs (0.057+/-0.056) mm, (0.064+/-0.053) mm and (0.033+/-0.035) mm, respectively]. Histological examinations revealed no obviously toxic effects on the eyes treated with pirenzepine.
CONCLUSIONTopical administration of the M1-selective muscarinic antagonist, pirenzepine, can prevent induced form-deprivation myopia in guinea pigs by inhibiting axial elongation without obvious damage to ocular tissues.

OBJECTIVETo analyze the effects of high-frequency electromagnetic field (HF-EMF, 30 MHz, 0-1600 V/m) on the apoptosis and ultramicrostructure of the hippocamp and demonstrate the cytotoxicity of hippocamp.
METHODS120 Wistar female adult rats were randomly divided into ten groups based on body weight with different levels of 30 MHz electromagnetic field (0, 25, 100, 400, 1600 V/m) for eight hours daily. Five group rats were irradiated for three days. The other five group rats were irradiated for fifty-six days. Weekly the rats were continuously exposed five days. The apoptotic rate of the hippocamp was detected with TUNEL System. Meanwhile, the ultramicrostructure was observed with the transmission electron microscope.
RESULTS(1) There was no significant difference on the apoptotic rate and pathological change of the hippocamp cell between the exposure and the control groups through short term experiment (P > 0.05). (2) The apoptotic rate of the granulocyte on the DG campus of the hippocamp in the 400 V/m group and the 1600 V/m group (0.165% +/- 0.049%, 0.189% +/- 0.049% respectively) were increased significantly (P < 0.01) through inferior chronic experiment compared with the control group (0.052% +/- 0.016%). Along with the increase of radiation dose, the ultramicrostructure of the neuron cell appeared more abnormal cells. Especially there were marked change on the neuron in the 1600 V/m group.
CONCLUSIONSThere is no association between cell apoptotic rate of the hippocamp and short period exposure to HF-EMF (30 MHz, 25-1600 V/m). However inferior chronic exposures to HF-EMF might induce the cytotoxicity, especially in the high dose exposure (1600 V/m) under our experiment.

OBJECTIVETo observe the effects of curcumin derivative on non-alcoholic steatohepatitis (NASH).
METHODS60 SD male rats were randomly divided into 5 groups. The NASH model was induced by high fat diet combined with carbon tetrachloride. These rats were then treated with curcumin and curcumin derivative, saline treating group as control. The serum biochemical parameters and liver histological examinations were observed. The TNF alpha, NF-kappa B and HMG-CoA reductase mRNA transcriptions of liver tissue were detected with RT-PCR. The protein expressions of TNF alpha and NF-kappa B were detected by western blot.
RESULTSCompared with the saline group, A remarkable reduction was observed in serum ALT (U/L), AST (U/L) and TC (mmol/L) in rats treated with curcumin derivatives [(69.20 +/- 27.58) vs (102.43 +/- 47.29), (158.00 +/- 39.15) vs (229.50 +/- 105.20) and (2.08 +/- 0.30) vs (2.58 +/- 1.02), P < 0.05]. The degrees of fibrosis were significantly alleviated; Compared with curcumin group, liver index and serum ALT, AST of curcumin derivative group were also significantly decreased [(4.88 +/- 0.62) vs (5.16 +/- 0.61); (69.20 +/- 27.58) vs (82.5 +/- 33.23); (158.00 +/- 39.15) vs (211.75 +/- 106.30), P < 0.05]; The liver steatosis and inflammation grade were also significantly improved .The gene transcriptions of TNF alpha, NF-kappa B and HMG-CoA reductase in curcumin derivative group were significantly lower than those in curcumin and saline group (P < 0.05).
CONCLUSIONThese results indicate that the water-soluble curcumin derivative displays superior bioavailability to the parent curcumin, which can effectively improve the lipid metabolism and delay the progression of hepatic fibrosis in rats with steatohepatitis.

Objective:To study the long-term clinical effect of transvaginal mesh (TVM) and pelvic floor reconstruction with native tissue repair (NTR) in the treatment of advanced pelvic organ prolapse (POP).Methods:Totally 207 patients with advanced POP who were treated in Hunan Provincial Maternal and Child Health Care Hospital from Jan. 2016 to Sep. 2019 were enrolled. The patient′s pelvic organ prolapse quantification were all at degree Ⅲ or above, and they all complained for different degree of symptoms. They were divided into two groups according to the different surgical methods, TVM group and NTR group. In TVM group, the mesh was implanted through the vagina for pelvic floor reconstruction, while in NTR group, the traditional transvaginal hysterectomy combined with uterosacral ligament suspension and anterior and posterior wall repair, as well as perineal body repair were performed. The median follow-up time was 60 months, during the follow up time, 164 cases (79.2%, 164/207) had completed follow-up, including 76 cases in TVM group and 88 cases in NTR group. The perioperative data and complication rates of the two groups were compared, and the subjective and objective outcomes of the two groups at 1, 3 and 5 years were observed, respectively. The objective efficacy was evaluated by three composite criteria, namely: (1) the distance from the farthest end of the prolapse of the anterior and posterior wall of the vagina to the hymen is ≤0 cm, and the descending distance of the top is ≤1/2 of the total length of the vagina; (2) determine the disappearance of relevant POP symptoms according to “Do you often see or feel vaginal mass prolapse?”; (3) no further operation or pessary treatment was performed due to prolapse. If the above three criteria were met at the same time, the operation is successful; otherwise, it was recurrence. The subjective efficacy was evaluated by the pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire-short form 7 (PFIQ-7).Results:The median follow-up time of the two groups was 60 months (range: 41-82 months). Five years after the operation, the subjective and objective cure rates of TVM group were 89.5% (68/76) and 94.7% (72/76), respectively. The subjective and objective cure rates in NTR group were 80.7% (71/88) and 85.2% (75/88), respectively. There were significant differences in the subjective and objective cure rates between the two groups ( χ2=9.869, P=0.002; χ2=3.969, P=0.046). The recurrence rate of TVM group was 5.3% (4/76), and that of NTR group was 14.8% (13/88). There was a significant difference between the two groups ( P=0.046). The postoperative PFDI-20 and PFIQ-7 scores of the two groups were significantly lower than those before surgery, and there were significant differences of the two groups before and after surgery (all P<0.05). Postoperative mesh exposure in TVM group was 1.3% (1/76). Conclusions:The long-term outcomes between the two groups show that the subjective and objective outcomes of pelvic floor reconstruction in TVM group are significantly higher than those in NTR group, and the recurrence rate is significantly lower than that in NTR group. TVM has certain advantages in the treatment of advanced POP.
