Sonodynamic therapy in many treatment methods of tumors, is a relatively new approach. Sonodynamic therapy as a treatment method is developed on the basis of photodynamic therapy. Compared to the lightwave, the ability to penetrate mammalian tissue of ultrasound is stronger. So sonodynamic therapy is a more promising therapeutic area. Many scholars have explored the clinical applications of sonodynamic therapy, and progress has been made in many areas. Because the female genitalia is connected the outside of body, it is more conducive that Sonodynamic therapy play a partial role. Sonodynamic therapy has some progress in the application of gynecology, and we hope it would have more progress in the treatment of endometrial disease.

OBJECTIVETo investigate the apoptosis regulation on hepatoma cells by HBx between genotype B and C.

METHODSGenotype B and C HBx gene fragments were amplified and inserted into green fluorescent protein (GFP) eukaryotic expression vector pEGFP-C1 to construct recombinant pGFP-XB and pGFP-XC. The pEGFP-C1, pGFP-XB and pGFP-XC were introduced into Bel-7402 cells by Fugene HD to obtain Bel-7402 cells expressing GFP. The transcription and expression of HBx gene were demonstrated by RT-PCR and Western Blot analysis. Bel-7402, Bel-7402/GFP, Bel-7402/GFP-XB, Bel-7402/GFP-XC cells were treated with adriamycin (2.5 microg/ml), and the apoptosis of the cells was determined by trypan blue exclusion, and flow cytometry analysis.

RESULTSRT-PCR and Western Blot analysis showed that HBx genes of genotypes B and C were transcribed and expressed in Bel-7402/GFP-XB, Bel-7402/GFP-XC cells. Trypan blue exclusion showed adriamycin induced time-dependent cell death in Bel-7402, Bel-7402/GFP cells while no significant cell death was observed in Bel-7402/GFP-XB, Bel-7402/GFP-XC cells. Flow cytometry analysis indicated that no significant differences of apoptosis rates of Bel-7402/GFP-XB (3.87%) and of Bel7402/GFP-XC (4.01%) were observed (P > 0.05), moreover, no significant differences of Bel-7402/ GFP-XB (3.87%), Be17402/GFP-XC (4.01%) and of the untreated cells. Apoptosis rates in Bel-7402/GFP-XB (3.87%), Bel-7402/GFP-XC (4.01%) cells were significantly lower than those in Bel-7402 (27.05%) and Bel-7402/GFP (29.14%) cells at 48 hours after the adriamycin treatment (P < 0.01).

CONCLUSIONSBel-7402 cell lines expressing GFP, GFP-XB and GFP-XC fusion proteins were successfully established. HBV X protein blocks adriamycin-induced apoptosis of Bel-7402 cells. There is no difference between HBx of genotype B and C in inhibiting apoptosis induced by adriamycin.

Objective　To observe the changes of serum soluble interleukin-6 receptor (sIL-6R) and soluble gp130 (sgp130) in patients with pregnancy induced hypertension. Methods　Enzyme linked immunosorbent assay (ELISA) was used to determine serum sIL-6R and sgp130 levels in 40 patients with pregnancy induced hypertension (study group), 20 normal non-pregnant women (control group I) and 20 normal pregnant women (control group II). Results　In study group, sIL-6R was (196.7±12.9) μg/L and sgp130 was (379.4±79.3) μg/L. In control group I, sIL-6R was (174.8±46.2) μg/L and sgp130 was (273.6±28.3) μg/L. In control group II, sIL-6R was (174.4±48.3) μg/L and sgp130 was (254.4±34.7) μg/L. SIL-6R and sgp 130 were higher in study group than those in control groups with significant difference (P<0.01). In study group, the more severe the patients, the higher the sIL-6R and sgp130 levels. There was significant difference (P<0.01). There was no difference in sIL-6R and sgp130 levels between control groups (P>0.05). Conclusions Serum sIL-6R and sgp130 levels are related to the development of pregnancy induced hypertension.

Background The surgery for retinal detachment induced by macular hole in high myopic eye has a lower success rate in comparison with other rhegmatogenous retinal detachment.A combination procedure of vitrectomy and heavy silicone oil tamponade for retinal detachment induced by macular hole in high myopic eye has been used,but different outcomes are reported.Objective This study was to assess the efficacy of heavy silicone oil tamponade for the treatment of retinal detachment with macular hole in high myopic eye.Methods The clinical data of 20 eyes of 20 patients who received vitrectomy combined heavy silicone oil tamponade surgery for retinal detachment induced by macular hole in high myopia under the informed consent in Beijing Tongren Eye Center from September 2007 to December 2009 were retrospectively analyzed.The 20 G vitrectomy was used during the surgery.In addition,other procedures,such as epiretinal membrane peeling,retinotomy,endo-laser photocoagulation,phacoemulsification and intraocular lens (IOL) implantation were optionally performed as necessary.No special position was required after the surgery.Heavy silicon oil was removed via pars plana,and retinal reattachment after heavy silicon oil removal was defined as success of surgery.Postoperative LogMAR vision,intraocular pressure,retinal reattachment and complications were observed and evaluated.Results The preoperative average spherical equivalent refractive error was (-14.3 ±3.0) D in the eyes.Among the 20 eyes,there were 7 (35％) recurrent retinal detachment and 7 eyes (35％) complicated with choroidal detachment preoperatively.After surgery,the retinas were reattached in 95％ eyes (19/20),including retinal reattachment after first operation in 18 eyes (90％) and after second surgery in 1 eye (5％).A localized retinal detachment was still existed after a second surgery in the other 1 eye.The mean LogMAR vision improved from preoperative 2.77 ±0.81 to postoperative 1.22±0.46 (P =0.000).All the phakic eyes developed different degrees of sub-capsular cataract.Long-term ocular hypertension was found in 2 eyes after surgery.Conclusions The combination of vitrectomy and heavy silicone oil endotamponade is a safe and effective approach to retinal detachment with macular hole in high myopic patients.This procedure may improve vision and offers comfortable position after surgery for the patients.

Objective:To investigate the clinical effects of health and safety management in elderly patients receiving gastroenteroscopy under sedation.Methods:From February 2018 to November 2019, 126 elderly patients admitted to the cadre medicine and gerontology department of our hospital to undergo gastroenteroscopy under sedation were included as research subjects.According to the digital random number method, they were divided into the control group and the test group(n=63, each group). The control group was given routine management, while the test group was given routine management plus health and safety management.Clinical effects and safety were analyzed and compared between the two groups.Results:There was no significant difference in scores of the Hamilton anxiety scale(HAMA)and the Hamilton depression scale(HAMD)between the two groups before intervention.After intervention, the scores of HAMA and HAMD were lower in the test group than in the control group[(39.2±3.1)scores vs.(48.6±2.1)scores, (40.1±4.1)scores vs.(52.6±5.5)scores, t=19.926 and 14.463, both P=0.000]. The incidence of postoperative complications was lower in the test group than in the control group(7.94% or 5/63 vs.19.05% or 12/65, χ2=14.209, P=0.002). The differences between maximum and minimum values of heart rate(HR), diastolic blood pressure(DBP), respiratory rate(RR)and systolic blood pressure(SBP)were lower in the test group than in the control group(all P<0.05). The length of the procedure was shorter and the anesthetic dose was lower in the test group than in the control group(9.11±2.56 min vs.13.56±3.05 min, 15.35±2.66 ml vs.21.67±6.15 ml, t=8.870 and 7.486, both P=0.000). Patient satisfaction was higher in the test group than in the control group( χ2=16.383, P=0.014). Conclusions:Health and safety management can improve emotional health, stabilize vital signs and enhance satisfaction in elderly patients undergoing gastroenteroscopy under sedation.

Formation of dermal collagen fiber is a complicated and sequential process with the progressive assembly of collagen. Collagen monomers form stepped and orderly protofibrils through longitudinal displacement. Subsequently, protofibrils or protofibrils and collagen are bonded by covalent bonds to form orderly lamellar structure of collagen fibers. Then collagen fibers are tightly wound into coarse collagen fiber bundles by covalent crosslinking. Decorin is a multifunctional small leucine-rich proteoglycan. It can prevent the aggregation of protofibrils by binding to the specific site of collagen with its core protein, and adjusting the spacing between the protofibrils with its glycosaminoglycan chain. Thus, by effecting the formation of collagen fibers with regulation of collagen assembly, decorin may help prevent scar formation and even promote regeneration.

OBJECTIVEThis study aimed to investigate the duration of gingival healing after the stage II surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration.

METHODSTwenty-nine periodontitis patients who had implantation surgery and achieved osseointegration were operated with stage II surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage II surgery. All implants were measured at the lowest point ofbuccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gingival change in each group between the second and first tests was determined, and the data were analyzed statistically.

RESULTSThe amount of gingival change of groups one, two, three, and four was (-0.25 +/- 0.66), (-0.04 +/- 0.52), (-0.70 +/- 0.77), and (-0.74 +/- 1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P > 0.05). However, a significant difference was found between groups two and three (P < 0.05), and the amount of gingival recession was 0.66 mm. No significant difference was found between groups three and four (P > 0.05), and the gingival achieved stability.

CONCLUSIONThe gingival recession achieves stability at the fourth week (after 28 d) after stage II surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.

Objective To investigate the effect of EGB on SOD, MDA of ventilator-induced lung injury in rats and its possible mechanisms. Methods Thirty male SD rats were randomly divided into 3 groups: control group (C group), high tidal ventilation group (H group) and EGB group (E group). The setting mechanical ventilation was VT=30 mL/kg, RR=40/min, I/E=1/3, PEEP=0 cmH2 O and FiO2=21%. The broncho-alveolar lavage fluid (BLAF) and serum were obtained for determination of the levels of SOD and MDA at the end of 4 h mechanical ventilation. The Lungs were removed, and the wet-to-dry weight ratio (W/D) and pulmonary pathologic changes were measured. Results As compared with C group, W/D and the levels of MDA were significantly increased in H group, but the levels of SOD were reduced in H group. As compared with H group, W/D and the levels of MDA were significantly decreased in E group, but the levels of SOD were increased in E group. Pulmonary pathologic changes were alleviated in E group comparing with H group. Conclusion EGB injection may have a protective role against hyperoxia and induced pulmonary damage in rats.
