Objective To investigate the value of combined use of misoprostol and intravenous mixture of pethidine and droperidol during operative hysteroscopy. Methods A total of 168 cases scheduled for hysteroscopy were divided into 4 groups: Group Ⅰ (42 cases) was transvaginally given 0.4 mg misoprostol as monotherapy; Group Ⅱ (41 cases) was given 0.4 mg transvaginal misoprostol in combination with intravenous mixture of 50 mg pethidine and 2.5 mg droperidol; Group Ⅲ (43 cases) was given 0.4 mg transvaginal misoprostol combined with intravenous mixture of 100 mg pethidine and 5 mg droperidol; and Group Ⅳ (42 cases), intravenous mixture of 100 mg pethidine and 5 mg droperidol. The heart rate, breath rate, blood pressure, oxygen saturation, cervical responses, VAS scores and complications were assessed respectively. Results There were statistically significant differences regarding the degree of cervical dilatation, the operation time, and the used volume of cavity-distention media between the Group Ⅳ and the Group Ⅰ, Group Ⅱ, and Group Ⅲ, respectively (P0.05). Significant differences were observed in the analgetic effect in the 4 groups (?~2=86.325,P=0.000), among which the Group Ⅱ and Group Ⅲ were superior to the other two. All patients in the 4 groups represented a stable respiratory process and blood circulation, with no significant differences in the rate of adverse effects (?~2=1.649, P=0.648). Conclusions Transvaginal application of misoprostol offers a convincing effect for cervical dilatation. Combined use of misoprostol and mixture of 50 mg pethidine and 2.5 mg droperidol gives a satisfactory analgetic effect during operative hysteroscopy.

Objective To investigate the changes of lead,zinc,copper,iron and calcium in blood of chronic poisoned infantal mice.(Methods) Forty-eight 21 day-old kunzea mice were randomly divided into 4 groups,each having 12 mice.Distilled water group was as control group and other three lead acetate poisoning groups had a dose of 10,20,40 mg/kg,respectively.The poisoning was carried out by lavage once a day,and consecutively for 46 days.Eyeballs of mice were picked then for blood sampling,and BS trace element analysis grapher was used to determine level of lead,zinc,copper and iron.Level of calcium was measured by Dimentional-RXL auto-biochemistry analysis meter.Results The lead and zinc levels in poisoned mice blood were increased with increasing lead acetate level administration,while zinc level changed inversely with lead acetate level.Significant differences were shown among control group and poisoning groups in terms of lead(P0.05).Conclusion Lead posioning can lead to zinc decreasing and copper(increa)-sing,which suggests that zinc works as a poential antidote of lead poisoning.

Objective: To examine the effect of dietary behaviors on handgrip strength loss among the elderly, so as to provide insights into the prevention of handgrip strength loss. Methods : Based on the health surveillance cohort among the elderly in Zhejiang Province, two villages or communities were randomly sampled from each of Shaoxing and Zhoushan cities using a multi-stage cluster sampling method, and all residents that had lived in local areas for one year and longer and had an age of 60 years and older were enrolled. Participants' demographics, dietary behaviors, smoking, drinking, and exercise were collected through questionnaire surveys, and the height, body weight and handgrip strength were measured. The handgrip strength loss was diagnosed according the 2019 Consensus Update on Sarcopenia Diagnosis and Treatment proposed by Asian Working Group for Sarcopenia, and the effect of dietary behaviors on handgrip strength loss was examined using a multivariable logistic regression model. Results: A total of 1 265 residents were enrolled, with a mean age of (70.67±7.30) years, and including 565 men (44.66%) and 700 women (55.34%). The overall prevalence of handgrip strength loss was 42.85% among the participants, and the prevalence was 40.35% in men and 44.86% in women, respectively. Multivariable logistic regression analysis showed that nut intake for 1 to 3 times a week (OR=0.180, 95%CI: 0.088-0.367) and for 4 to 6 times a week (OR=0.241, 95%CI: 0.113-0.514) led to a reduced risk of handgrip strength loss among the elderly, and intake of sugary drinks for 4 to 6 times a week led to an increased risk of handgrip strength loss among the elderly (OR=2.298, 95%CI: 1.120-4.714) after adjustment for age, body mass index, educational level and exercise. Conclusion Intake of nuts and sugary drinks may affect the development of handgrip strength loss among the elderly.

And the ADL was lower in patients operated within 8. 0 hours than in patients operated over 8. 1 hours [≤3.0 hours group: (2. 60± 1.07)scores; 3.1-8.0 hours group: (3. 06±0. 91 )scores;8. 1-24.0 hours group: (4.00±0.67) scores;over 24.0 hours group:(3.68±1.32)scores,Q＞3. 1,P＜0.05].Conclusions The minimally invasive surgery of intracranial hematoma within 8.0 hours can mitigate the cytotoxicity-damaged BBB so as to lighten brain edema and improve the patients quality of life.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.
