OBJECTIVE:To study the in vitro percutaneous absorption of neostigmine cream.METHODS:Using isolated mouse skin as permeation barrier,the influence of different concentrations of azone on percutaneous permeation of neostigmine was studied.RESULTS:Azone could obviously enhance the percutaneous permeation of neostigmine,and the accumulative permeation quantity of neostigmine cream containing2%and5%azone increased7.17%and11.87%respectively compared with that of cream without azone.CONCLUSION:The percutaneous permeability of neostigmine cream is satisfactory and the best concentration of azone in enhancing permeation seems to be5%.

After investigating conditions of 210 seven-year system medical students' extracurricular reading,we discovered that most medical students were rather interested in extracurricular reading,but there existed certain problems in the aspects of the arrangement of time and choice of books etc,which not only lowered the quantity of the student' extracurricular reading,but was disadvantageous to the effective display of the humanities education.Therefore,it was necessary to enhance the seven-year system medical students' extracurricular reading.

Tyrosine kinase inhibitors (TKIs) are used as the primary first-line treatment for advanced hepatocellular carcinoma, and the combination of immune checkpoint inhibitors (ICIs) and angiogenesis inhibitors have also been recommended as first-line treatment recently. For hepatocellular carcinoma patients with portal vein tumor thrombus, hepatic artery infusion chemotherapy (HAIC) is supported by progressively more evidence in improvement in the overall survival benefit. Based on relevant literatures and combined with clinical practices, the authors investigate the clinical application and development trends of TKIs, ICIs and HAIC in the first-line treatment for advanced hepatocellular carcinoma.

Objective To explore the effects of H.pylori and crude extracted proteins secreted by H.pylori(broth culture filtrate protein,BCF-P)on acid secretion from isolated rabbit parietal cells.Methods Parietal cells from rabbit gastric mucosa were isolated and enriched with digestion and elutriation.H.pylori(NCTC 11637,CagA+ VacA+)were grown in liquid broth culture and BCF-P was precipitated with ammonium sulfate.The vacuolation activity of BCF-P was evaluated with neutral red dye uptake test in HeLa cell.Isolated parietal cells were incubated with H.pylori(bacteria/cell=100∶1)for 2 h and 16 h,or BCF-P(100μg/ml)for 1 h and 12 h.Acid secretion from parietal cells was studied using 14C-aminopyrine(14C-AP)accumulation indirectly and H+-K+ ATPase α subunit mRNA expression was assessed using RT-PCR.Results (1)BCF-P containing vacuolating cytotoxin(VacA)with vacuolation activity on HeLa cells had positive result on neutral red uptake test.(2)The basal expression of H+-K+ ATPase α subunit mRNA could be detected in isolated parietal cells and 14C-AP accumulation was significantly increased in response to the stimulation of histamine with different concentrations for 30 min(P＜0.05).These results indicated that the isolated parietal cells retain relative intact acid secretion function.(3)The histamine(1.0×104 mol/L)stimulated acid secretion was inhibited sustainedly in response to H.pylori by 81% at 2 h and by 94% at 16 h(P＜0.05).However,H+-K+ ATPase α subunit mRNA expression was up-regulated in tlle acute period(2 h)and was down-regulated in the chronic period (16 h)by H.pylori(P＜0.05).(4)BCF-P significantly inhibited the histamine-stimulated acid secretion by 24% at 1 h and by 58% at 12 h(P＜0.05),and this inhibition was accompanied by the down-regulated expression of H+-K+ATPase α subunit mRNA.Conclusions Intact H.pylori and VacA secreted by H.pylori could directly inhibit histamine-stimulated acid secretion from parietal cells and this inhibition may be mediated by the down-regulated H+-K+ ATPase expression.

Objective To assess the effect of variable durations of warm ischemia on renal function early after laparoscopic partial nephrectomy ( LPN ) and make the definite safety duration of renal warm ischemia.Methods The clinical data of 76 patients treated with LPN from October 2012 to June 2014 were retrospectively analyzed.The patients were divided into 3 groups based on warm ischemic time,namely group A (28 cases) with warm ischemia time less than 20 min,group B (34 cases) with warm ischemia time more than 20 min and less than 30 min, group C ( 14 cases ) with warm ischemia time more than 30 min.LPN was performed with renal artery clamping alone in all the patients.Preoperative and postoperative renal scintigraphic scan was performed to access glomerular filtration rate ( GFR) in all patients.The GFR values were compared among before, 1 week, 1 month and 3 months after operation.The factors predicting the early renal injury were assessed by multivariate regression analysis.Results The renal GFR of the kidney underwent LPN decreased 19.43(17.70,22.06) ml/min at 1 week,17.04(13.94,20.70) ml/min at 1 month,13.82(10.72,18.73) ml/min at 3 months after the surgery in group C,respectively.In group A, the renal GFR of the operated-side decreased 12.07(10.91,13.42) ml/min,10.04(9.16,11.75) ml/min, 8.44(7.07,9.72) ml/min,respectively.In group B, the renal GFR of the operated-side decreased 13.64 (12.48,16.72) ml/min,10.29(9.17,14.27)ml/min,9.63(7.85,12.59) ml/min,respectively.The GFR decreased greater in group C than that in group A and B(P<0.05).The total renal GFR decreased (10.70 ± 4.93)ml/min at three months in group C,compared with (5.64 ±4.12)ml/min in group A and (6.37 ± 4.32)ml/min in group B,respectively.The decreased value in group C was greater than that in group A and B(P<0.05).However,the differences of the total renal GFR among the 3 groups were not significant at 1 week and 1 month(P>0.05).The multivariate regression analysis revealed that warm ischemia duration was the independent risk factor of the early renal injury.Conclusions Warm ischemia duration is the major factor regarding the early renal recovery after LPN.Warm ischemia time more than 30 min may not only greatly affect the renal function but also the renal function recovery rate.

Objective To observe the curative effect of cervical traction combined with low-cycle or intermediate frequency electrical current in cervical vertebrae.Methods 171 patients with cervical vertebrae were randomly divided into the therapy group and control group,86 cases in therapy group were performed the curative measure of cervical traction and low-cycle,85 cases in control group underwent the curative measure of cervical traction and intermediate frequency electrical current.Both of the two groups carried out continuous therapy for 10 days.Results There was significant difference before and after treatment within each group in CASCS score(P ＜ 0.01)and there was also significant difference after treatment between the two groups(P ＜ 0.05),the effective rate of therapy groupwas significant higher than that of control group(P ＜ 0.05).Conclusion The methods of cervical traction and low cycle or intermediate frequency electrical current has better curative effect in cervical vertebrae and cervical traction and low-cycle do much benefit in cervical vertebrae treatment.

Objective To observe and analyse the efficacy of retrograde gonarthritis with interference current and drug-iontophoresis direct current. Methods 185 patients with retrograde gonarthritis were randomly divided into treatment group 92 cases and control group 93 cases. The patients in treatment group underwent interference current and drug-iontophoresis direct current and patients in control group performed modulated medium frequency drug-ionto-phoresis direct current for two treatment courses. Results The comprehensive score of various kind of symptom such as pain、swelling、flexion、walking ability, up-down stair ability in treatment group significantly improved than that of control group (P < 0.01). Conclusion The interference current and drug-iontophoresis direct current is one of effec-tive and safe measurement in treating arthritis with main manifestation of pain and soft tissue disease.

Obesity often results when regular caloric intake exceeds the energy expenditure. Hypothalamus is the center that regulates feeding and energy balance inside the body, especially the lateral hypothalamic area (LHA) and ventromedial nucleus (VMN). Acupuncture-moxibustion has achieved significant progress in treating simple obesity, and the relevant studies have revealed the central action mechanism underlying the treatment. By reviewing the literatures associated with the mechanism studies on acupuncture-moxibustion for simple obesity, this article is going to provide clinical and scientific guidance for the treatment of simple obesity with acupuncture-moxibustion.
