Thinning and atrophy of sclerotic tissues play an important role in the development of high myopia. High myopic eyes had the thickest sclera at the posterior pole and the thinnest sclera at the equator. Most clinical studies found that scleral thickness was negatively correlative with the axial length. Patients complicated with posterior staphyloma had even thinner sclera, and its height was negatively related with the scleral thickness. At present, the main measurement methods for scleral thickness of high myopic eyes include histological measurement, enhanced depth imaging optical coherence tomography (OCT), and swept-source OCT. Following the development of OCT technique, it gradually becomes feasible to carry out studies on sclera thickness in mildly and moderately myopic populations, which is helpful to illuminate the mechanism of action of sclera on the onset and progression of high myopia.

【Objective】To observe the therapeutic effect of oral use of Neiyi Pill(composed of Radix Salviae Miltiorrhizae,Sanguis Draxonis,Rhizoma Sparganii,Rhizoma Curcumae,Semen Persicae,Radix Notoginseng,Radix Angelicae Sinensis,Ramulus Cinnamomi,Rhizoma Cyperi,Radix Achyranthis Bidentatae,etc.) combined with enteroclysis of Neiyi Enema(composed of Radix Salviae Miltiorrhizae,Sanguis Draxonis,Semen Persicae,Rhizoma Curcumae,Radix Paeoniae Rubra,Rhizoma Polygoni Cuspidati,etc.) for dysmenorrhea induced by endometriosis(EMS).【Methods】Fifty-eight patients diagnosed as endometriosis by laparoscopy were divided into 3 groups by randomized single-blind method.Group A(n=16) was treated with Neiyi Pill orally,Group B(n=24) with Neiyi Pill orally combined with enteroclysis of Neiyi Enema and Group C(n=18) with danazol orally.The 3 groups respectively received the corresponding treatment for 3 successive menstrual cycles(MC).Dysmenorrhea scoring was carried out according to the Guide for Clinical Research of New Chinese Herbal Medicine before treatment and after 1,2 and 3 menstrual cycles.The effects on symptoms of dysmenorrhea,lumbosacral discomfort and irritative symptom of rectum,signs of tenderness and nodule in posterior fornix of vagina and adnexal masses,and syndrome of blood stasis were observed.Meanwhile,the adverse reactions were also monitored.【Results】After treatment,effect on relieving dysmenorrhea in group B was superior to that in group C(P0.05).Effect on lumbosacral discomfort and syndrome of blood stasis in groups A and B was superior to that in group C(P0.05).Effect on irritative symptom of rectum,tenderness and nodule in posterior fornix of vagina and adnexal masses in group B was superior to that in group C(P0.05).【Conclusion】Oral use of Neiyi Pill combined with enteroclysis of Neiyi Enema has a better effect for endometriosis than only oral use of Neiyi Pill only or danazol,and has no obvious adverse reactions.

Objective To investigate the short-cycle repeated transurethral resection ( Re-TURBT) combined pirarubicin treatment of T2 muscle invasive bladder tumor efficacy and safety.Methods From October 2010 to December 2013, 56 clinically diagnosed cases of bladder cancer were divided into two groups;the experimental group was taken a short-cycle repeat transurethral resection surgery, and the con-trol group taken along open surgery to remove the tumor and its surrounding 2cm bladder tissue, postopera-tive patients were given pirarubicin infusion therapy.Results Each patient completed the trial.For the ex-perimental group, blood loss and operative time was significantly lower than the control group ( P <0.05). For experimental group after 3 months, 6 months, and 12 months, maximum bladder capacity ( MBC) and patient perception of bladder condition ( PPBC) were significantly higher than control group ( P <0.05 ) . For experimental group after 3 months and 6 months, maximum urinary flow rate ( Qmax) was significantly higher than control group ( P <0.05) , but no significant difference between two groups at 12 months.The incidence of adverse events, vascular endothelial growth factor ( VEGF) , and a total recurrence rate showed no significant difference ( P >0.05).For experimental group, bladder perforation in 1 case, 1 case was forced to open surgery, the incidence rate was about 6.7%.Conclusions The short-cycle repeated trans-urethral resection combined pirarubicin treatment of T2 invasive bladder tumor was simple, effective and se-curity.

Objective:To provide recommendations for further improvement of resident standardization training in Shenzhen according to carrying on the appraisal to the present stage of the training work. Methods:A self-designed questionnaire was used to investigate resident trainees. Results:We had collected 870 questionnaires with 86. 8% ef-fectively received rate. The resident trainees’ degree of satisfaction to the base conditions and management is more than 50%. While the degree of satisfaction to the training program is 33. 3%. Compared with the outside training base , the training conditions and management level is poor and lower in local training base. The effect of training pro-gram is better in outside training group than local group. Conclusions: Basement management, assessment, training schedule and trainees’ payment need to be improved.

Objective:To verify the accuracy and feasibility of radioactive 125I seed implantation assisted by an optical navigation system and a 3D-printing non-coplanar template in the treatment of recurrent head and neck cancers. Methods:A total of 12 patients with recurrent head and neck cancer treated with radioactive 125I seed implantation assisted by an optical navigation system and 3D-printing non-coplanar template were enrolled from Dec 2018 to Dec 2019.The pre-plan and post-implant implantation needle number and implanted seed number were recorded.Meanwhile, their dosimetric parameters were compared, including D90, minimum peripheral dose (MPD), V100, V150, V200, conformity index (CI), external index (EI), and the homogeneity index (HI) of the target volume. Results:The median lesion volume was 31.5 cm 3, the median number of seeds was 61.5, and the median prescription dose was 130 Gy.The means of the pre-plan D90, MPD, V100, V150 and V200 were 134.2, 64.6, 93.3, 75.3 and 39.3 Gy, respectively, while those of post-implant D90, MPD, V100, V150, and V200 were 146.7, 68.94, 97.47, 80.40 and 48.30 Gy, respectively, with no statistically significant difference ( P>0.05). Meanwhile, there was no statistically significant difference between the pre-plan and post-implantation needle number, implanted seed number, CI, HI, and EI ( P>0.05). In terms of postoperative dose quality assessment, eight cases were rated excellent (66.6%) and four cases were rated good (33.3%). Conclusions:Radioactive 125I seed implantation assisted by an optical navigation system and 3D-printing non-coplanar template can be accurately performed in the treatment of recurrent head and neck cancer, with good consistency between pre-plan and post-implant dosimetric parameters and thus of prospective potential in clinical application.

Objective:To analyze the clinical characteristics of lung abscess related to adenovirus (ADV).Methods:The data of 5 cases suffering from pulmonary abscess by ADV in Guangzhou Women and Children′s Medical Center from January to December 2019 were collected, including general information, clinical characteristics, examination and follow up visits.Results:The age of the patients ranged from 4 months to 12 months and the mean age was 8.6 months.All of them had fever and the degree was more than 39 ℃.What′s more, they had the history of cough and sputum.Somebody had dyspnea and pleural effusion.The imaging examinations of 5 cases strongly suggested that the interstitial and parenchymal lung disease subsequently appeared different sized cystic shadow, liquid flat cystic shadow, thickened wall empty tissue image, while some cases displayed the pleural effusion.The ADV-PCR or ADV-IgM were positive in the children, while the C-reactive protein, white blood cells and neutrophile were higher than the normal, but some were not.All the platelet count and lactate dehydrogenase were higher than the normal.Three children experienced the surgical treatment and their pathologic result revealed lung abscess.All the children were cured after the treatment, with good prognosis.Conclusions:Lung abscess related to ADV was rare in children and its system was not clear.If children who suffered from ADV were not cured after the treatment for a long time, the CT scan can differentiate whether it was combined with the complication of lung abscess or not.Early therapy for these patients could obtain satisfactory prognosis.

Prolonged instances of arrhythmia may not only exacerbate original heart diseases,but also cause hemodynamic disorders and even sudden death.Catheter ablation,which utilizes a catheter to directly destroy the underlying arrhythmia substrate,has become the main treatment.Recent advances have enabled noninvasive delivery of precise arrhythmia radioablation with electrophysiology-guided stereotactic body radiation therapy(SBRT),termed stereotactic arrhythmia radioablation(STAR).The progress of STAR was reviewed in this paper.

Objective To investigate clinical effectiveness and feasibility of adult liver transplantation using the left lobe.Methods We analyzed the clinical data of 9 recipients who underwent adult liver transplantation using left lobe from March 2007 to April 2011,including 5 cases receiving split liver transplantation and rest 4 cases receiving living donor liver transplantation.Mean graft weight was 444.6 g (325-570 g) and mean graft-recipient weight ratio was 0.886％ (0.65％-1.18％ ).The middle hepatic vein was reserved in 7 cases.Six cases underwent Laden back surgical and 3 cases underwent classical surgical procedures.During the operation,PVP of 4 cases exceeded 20 mm Hg (2.67 kPa),3 cases were subjected to splenic artery ligation and 1 case to splenectomy.All recipients after operation were treated with triple drug maimenance therapy of Tacrolimus,Mycophenolate Mofetil and corticosteroids.We followed-up the recipients long-term,and the incidence of vascular complications and biliary complications,patient and graft survival,restoration of liver function were observed.Results No serious complications occurred in 4 living donors subject to left lobotomy and the liver function had a good recovery.The median follow-up period of these 9 recipients was 15.7 months ( 1 month to 51 months).Overall 1-year patient and graft survival rate was 77.8％ (7/9).Two cases died after operation.In the remaining 7 cases,1 case had initial poor graft function,and cases had initial good graft function.The main complications after operation included biliary anastomotic strictures in 1 case,small-for-size syndrome in 1 case,portal vein thrombosis in 1 case,initial poor graft function in 1 case and abdominal infection in 2 cases.Conclusion With strict for selecting and good matching donor-recipient,adult liver transplantation using left lobe is safe and feasible.
