OBJECTIVETo search for an optimal protocol and freezing conditions for the cryopreservation of microamount round spermatids of the mouse.

METHODSWe compared the survival rates of frozen-thawed microamount round spermatids of the mouse achieved by vitrification or standard slow freezing with different concentrations of glycerol (5, 7, or 9%) and different lengths of equilibrium time (0, 15, 30, 45, or 60 min).

RESULTSUnder the conditions of 7% glycerol and 30 min equilibrium, both vitrification and standard slow freezing achieved high survival rates of spermatids, and the former obtained an even higher rate than the latter ([72.9 ± 15.4]% vs [58.2 ± 17.7]%, P < 0.05).

CONCLUSIONA high rate of frozen-thawed microamount round spermatids of the mouse can be achieved by vitrification under the conditions of 7% glycerol and 30 min equilibrium.

Concurrent chemoradiotherapy is the optimal regimen for patients with inoperable locally advanced non-small cell lung cancer (LA-NSCLC).The application of new technologies such as positron emission tomography (PET)/CT and four dimensional CT (4D-CT) enhances the accuracy of radiotherapy and decreases adverse reaction.Induction chemotherapy and consolidation chemotherapy do not show benefit to survival.The targeted therapy and immunotherapy have the potential of improving the outcomes of inoperable LA-NSCLC.

Objective To investigate the influence of nebulized Pulmieort respules inhalation after endoscopic sinus surgery (ESS)on the expression of epithelial Na~+ channel(ENaC)protein in nasal mucosa. Methods Forty-four patients with nasal polyps undergoing ESS were randomly divided into Pulmieort respules treatment group(n=21,nebulized Pulmieort respules inhalation for 10 d after ESS)and Rhinocort control group(n=23,Rhinoeort aqueous nasal spray for 10 d after ESS).All the patients were performed biopsy of membrane on the residual middle turbinate 14 d after ESS,eosinophils (Eos)and neutrophils(Neu)per hundred inflammation cells were counted under microscope during ESS and after ESS,and the expression of ENaC protein was detected by immunofluorescence assay. Results The percentages of Eos and Neu decreased in two groups after treatment,and the percentage of Neu in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.05).The expression of ENaC protein after treatment in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.01). Conclusion Application of pulmieort respules after ESS can decrease Neu infiltration and inhibit expression of ENaC protein,which can relieve acute inflammation and edema of nasal mucosa.

Objective To compare the clinical efficacy between endoscopic thyroidectomy via breast approach and conventional open thyroidectomy in patients with nodular goiter.Methods A series of 75 patients with unilateral nodular goiter was divided into two groups,either receiving endoscopic thyroidectomy through breast approach(Endoscopic Group,24 cases)or conventional open thyroidectomy(Open Group,51 cases).The therapeutic efficacy was compared between the two groups.Results In the Endoscopic Group,the endoscopic operation was successfully performed in 23 cases,whereas a conversion to open surgery was needed in 1 case because of large nodule(6 cm in diameter)and extensive adhesion of infrahyoid muscles(resulted from a previous injection therapy).The operating time was significantly longer in the Endoscopic Group(100.4?26.6 min)than in the Open Group(73.5?14.5 min)(t=5.627;P=0.000).The postoperative drainage volume in the Endoscopic Group(66.7?24.9 ml)was significantly more than that in the Open Group(13.3?6.4 ml)(t=14.403,P=0.000).The postoperative hospital stay was significantly longer in the Endoscopic Group(4.3?1.1 d)than in the Open Group(3.6?0.9 d)(t=2.886;P=0.005).The Endoscopic Group had significant higher hospital costs(11 572?1675.1 yuan)than the Open Group(5015.9?1211.0 yuan)(t=19.058;P=0.000).And a satisfactory cosmetic result was achieved in significantly more patients in the Endoscopic Group(22/24 cases)than in the Open Group(34/51 cases)(?2=7.235;P=0.007).There was no significant difference in intraoperative blood loss between the Endoscopic Group(22.5?15.3 ml)and the Open Group(18.3?7.5 ml)(t=1.273;P=0.207),and in consumption of analgesics between the Endoscopic Group(9/24 cases)and the Open Group(21/51 cases)(?2=0.028;P=0.867),respectively.No severe complications were encountered,such as massive hemorrhage,injuries of the recurrent or superior laryngeal nerve,or parathyroid gland injury.During a follow-up for 6 months,none of the patients was found recurrence after surgery.Conclusions Both breast approach endoscopic thyroidectomy and conventional open thyroidectomy are safe and effective.The former gives better cosmetic outcomes but slower recovery and high hospital costs compared to the latter.

Objective To investigate the protective effect of penehyclidine hydrochloride pretreatment on focal cerebral ischemia/reperfusion injury and expression of caspase-3 in rats.Methods Sixty male Sprague-Dawley rats weighing 250-300 g were randomly divided into 3 groups(n=20): control (C) group in which sham operation was performed; ischemia-reperfusion (I-R)group, in which saline (2.0 mg?kg-1)was administered for intraperitoneal injection 30 min before anesthesia,then the ischemia model was made by occlusion of the left middle cerebral artery for 120 min; penehyclidine hydrochloride pretreatment (P) group, in which penehyclidine hydrochloride(2.0 mg?kg-1)was administered for intraperitoneal injection 30 min before anesthesia,then the same 120 min focal cerebral ischemia was performed as described in I-R group.At the end of 24 h reperfusion the animals were decapitated and the brains were removed.The volume of cerebral infarction was detected with TTC staining;Coronal sections including hippocampal tissue were obtained for HE staining.The levels of caspase-3 mRNA expression in hippocampus were detected by using semi-quantitative RT-PCR technique.Results Compared with group I-R,the volume of cerebral infarction in group P were reduced significantly(P

Objective To assess the value of intraoperative ultrasonography during the uterus septum resection under a hysteroscope.MethodsThe uterus septum resection was performed under the guidance of transabdominal ultrasonography by using a hysteroscope in 30 patients.The operative procedure and the position of the hysteroscope were monitored,and the depth of the dissection and thickness of the myometrium in the fundus uteri were measured with transabdominal ultrasound during the operation.ResultsThe thickness between the incisal surface and serosal layer in the fundus uteri was within the normal limits in 28 cases.In 2 cases,the tissue was over-ectomized.The position of the urethral catheter balloon was correct in all of the 30 cases.Three months after the procedure,reexamination by transvaginal ultrasonography showed that the uterine cavity was normal in the patients.ConclusionsIntraoperative ultrasonography is quick,safe and precise for monitoring uterus septum resection.It is valuable for establishing surgical strategy and reducing operative complications.
