ABSTRACT
With the rapid development of science and technology and the wide application of electronic products, the number of patients with high myopia is gradually increasing. Meanwhile, owing to the continuous optimization of surgical skils and the continuous advancement in materials of posterior chamber intraocular lens and manufacturing processes, implantable collamer lens(ICL)V4c implantation has gradually become one of the main surgeries for the treatment of high myopia. In the rapid era of social information, people pay more attention to the long-term efficacy after ICL V4c implantation, they not only want clear vision, but also the pursuit of visual comfort and durability. Therefore, this paper will specifically discuss the research progress of the post-implantation efficacy of ICL V4c with at least 2 a of follow-up observation within 3 a, aiming to review the latest research progress on the long-term efficacy of ICL V4c implantation from the three dimensions of visual quality, safety, efficacy and stability and possible surgical complications after ICL V4c implantation.
ABSTRACT
@#Objective To analyze the surgical efficacy and influencing factors of myasthenia gravis (MG) patients with thymic atrophy after thymectomy. Methods The clinical data of MG patients with thymic atrophy undergoing thymectomy between October 2014 and May 2018 in Daping Hospital of Army Medical University and Shijiazhuang People Hospital were retrospectively analyzed. Results A total of 71 patients were collected, including 40 males and 31 females with a mean age of 45.17±12.42 years. All patients received the surgery successfully. After the surgery, 20 (28.17%) patients were stable remission, 12 (16.90%) patients were minimal manifestation status,19 (26.76%) patients were improved, 5 (7.04%) patients showed no change, 3 (4.23%) patients were worsened, 10 (14.08%) patients were exacerbated and 2 (2.82%) patients were dead. Multivariate logistic regression analysis showed that the preoperative illness duration (OR=4.61, 95%CI 1.13-18.85, P=0.03), and postoperative pyridostigmine combined with immunosuppressive (OR=0.12, 95%CI 0.03-0.45, P=0.00) were independent risk factors for long-term efficacy of thymectomy for MG patients with thymic atrophy. Conclusion Early surgery after diagnosis of MG and postoperative pyridostigmine combined with immunosuppressive treatment is beneficial to the prognosis of MG patients with thymic atrophy.
ABSTRACT
AIM: To investigate long-term efficacy and safety of patients after excimer laser in situ keratomileusis(LASIK)surgery in 20a.METHODS: A retrospective study.Patients who underwent LASIK in our hospital from January 1998 to December 2001 were recruited. The patients were notified by telephone to the outpatient for follow-up. The collected data included demographic characteristics(gender and age), preoperative uncorrected distance visual acuity(UCVA)and best corrected visual acuity(BCVA), preoperative diopter, intraoperative corneal flap thickness and corneal stromal residual thickness(RST). The main indicators were long-term efficacy index, safety index, UCVA, BCVA, corneal thickness and axial length. The slit lamp, fundus and optical coherence tomography(OCT)examination were performed at the same time.RESULTS: A total of 95 patients(190 eyes)were recruited. At the final postoperative visit, there were 71 patients(142 eyes, 74.7%)had UCVA≥1.0, and 82 patients(164 eyes, 86.3%)had BCVA≥1.0. There were 2 eyes among them had bad BCVA(≤0.6)due to macular retinoschisis and glaucoma, respectively, while other patients' BCVA was 0.8. There was no significant correlation between the UCVA and BCVA of patients after surgery in 20a and the factors such as age at surgery, preoperative diopter and corneal thickness(P>0.05), but there was a negative correlation with the increase of axis length(rs=-0.32, -0.31, all P<0.05). UCVA and BCVA were positively correlated with corneal stromal residual thickness at the last postoperative follow-up(P<0.05). The safety and efficacy indexes of LASIK after surgery in 20a were 1.00±0.10 and 0.83±0.27, respectively. During the follow-up, no patients were found to have corneal ectasia and complications related to corneal flap, and no patients underwent secondary surgery. No patients with corneal dryness were found after silt lamp examination.CONCLUSION: LASIK after surgery in 20a shows good safety and efficacy.

ABSTRACT
Objective:To investigate the application value of totally laparoscopic trans-abdominal-hiatal approach in the radical resection of Siewert type Ⅱ adenocarcinoma of esophago-gastric junction (AEG).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 45 patients with Siewert type Ⅱ AEG who were admitted to the Affiliated Hangzhou First People′s Hospital, Zhejiang University School of Medicine from May 2017 to December 2020 were collected. There were 28 males and 17 females, aged from 35 to 85 years, with a median age of 64 years. All patients underwent radical resection of AEG by totally laparoscopic trans-abdominal-hiatal approach with gastrointestinal anastomosis using proximal gastrectomy with double-tract anastomosis or total gastrectomy with esophagojejunointestinal anastomosis and digestive reconstruction using transdiaphragmatic-hiatal superior overlap esophagojejunostomy. Observation indicators: (1) surgical and postoperative situations; (2) postoperative histopathological examination; (3) follow-up and survival situations. Follow-up using outpatient examination and telephone interview was performed to detect survival of patients and tumor recurrence and metastasis up to March 2021. Measurement data with normal distribution were presented as Mean± SD and measure-ment data with skewed distribution were presented as M(range). Results:(1) Surgical and post-operative situations: all 45 patients underwent radical resection of AEG by totally laparoscopic transabdominal-hiatal approach successfully, including 35 cases undergoing total gastrectomy with esophagojejunointestinal anastomosis and 10 cases undergoing proximal gastrectomy with double-tract anastomosis. The total operation time, time of lower mediastinal lymph node dissection, time of superior overlap esophagojejunostomy, volume of intraoperative blood loss, time for initial out-of-bed activities, time to first flatus, time to initial liquid diet intake, time to drainage tube removal of the 45 patients were (235±32)minutes, (25±8)minutes, (45±10)minutes, (70±13)mL, (20±8)hours, (2.3±0.2)days, (2.6±0.8)days and (6.2±1.1)days, respectively. Eleven of 45 patients under-went postoperative complications and none of patient died during perioperative period. The post-operative duration of hospital stay of 45 patients was (10±3)days. (2) Postoperative histopatho-logical examination: all 45 patients had negative upper surgical margin. The length of proximal margin, tumor diameter, total number of lymph lodes harvested and number of lower mediastinal lymph nodes harvested were (2.5±0.5)cm, (2.9±0.8)cm, 35.0±4.0 and 2.4±0.8, respectively. Patholo-gical examination showed adenocarcinoma in all 45 patients with pTNM staging as 5 cases of stage ⅠB, 8 cases of stage ⅡA, 21 cases of stage ⅡB and 11 cases of stage ⅢA. (3) Follow-up and survival situations: 45 patients were followed up for 3 to 46 months, with a median follow-up time of 26 months. During follow-up, 8 of 45 patients died. Of the 37 patients survived, 3 cases underwent liver metastasis and 3 cases underwent bone metastasis, lung metastasis or peritoneal metastasis respec-tively.Conclusion:Total laparoscopic transabdominal-hiatal approach is safe and feasible in the treatment of Siewert type II AEG with a satisfactory clinical efficacy.
ABSTRACT
Objective@#To evaluate the long-term healing rate of transsphincteric anal fistula treated with anal fistula plug procedure and the risk factors affecting the healing of anal fistula.@*Methods@#A retrospective case-control study was conducted to analyze the clinical data of 207 patients with transsphincteric anal fistulas who received anal fistula plug procedure at the Department of General Surgery, Beijing Chaoyang Hospital of Capital Medical University from August 2008 to September 2012. Inclusion criteria: (1) consistent with the diagnosis of transsphincteric anal fistula: the anal fistula passed through the internal and external sphincter; (2) complete data; (3) initial treatment with anal fistula plug procedure. Exclusion criteria: (1) acute rectal or perianal infection or poorly controlled focal infection; (2) recent incision and drainage of perianal abscess or spontaneous rupture of abscess; (3) patients with malignant tumor; (4) patients with Crohn′s disease or ulcerative colitis; (5) patients with heart, liver, brain, lung or renal insufficiency; (6) cachexia due to various chronic wasting diseases; (7) patients could not tolerate surgery. Patients were followed up for anal fistula healing. The cumulative healing rate of patients with transsphincteric anal fistula was plotted using the Kaplan-Meier method, and the factors affecting anal fistula healing were explored by univariate and multivariate logistic regression analysis.@*Results@#There were 186 males and 21 females with age of 15 to 69 (mean 38) years. The duration of anal fistula was 3-60 (mean 15) months. Three patients had a history of previous episodes of perianal abscess and underwent incision and drainage of perianal abscess (all more than 3 months). During follow-up ending on October 31, 2018, 72 patients (34.8%) were lost to follow-up. Among 135 patients who were successfully followed up, the average follow-up period was 96 (75-124) months. Seventy-five patients had anal fistula healing, with healing rate of 55.6%. Kaplan-Meier survival curve showed that the healing time of anal fistula was prolonged and finally stabilized at 55.6%. In the patients who failed initial treatment with anal fistula plug packing, there were 6 cases whose anal fistula healed spontaneously without other treatment. Among them, 3 cases healed spontaneously 2 years and 3 cases 3 years after operation without recurrence. From 2008 to 2012, the annual healing rates of anal fistula plug treatment were 3/6, 61.5% (24/39), 42.1% (24/57), 12/15 and 12/18, respectively. Multivariate logistic regression analysis showed that the duration of anal fistula≥6 months (OR=3.187, 95% CI: 1.361-7.466, P=0.008) was an independent risk factor for anal fistula healing after treatment with anal fistula plug.@*Conclusion@#The long-term efficacy of anal fistula plug procedure in the treatment of transsphincteric anal fistula is positive, and this procedure should be implemented as soon as possible.
ABSTRACT
Objective To summarize the long-term efficacy of oral mucosal urethroplasty.Methods The clinical data of 324 patients with anterior urethral stricture who underwent oral mucosal urethroplasty from January 2013 to May 2018 were retrospectively analyzed.The patients were 27-65 years old with an average age of 47 years.Among them,51 patients had urethral meatal stenosis,174 patients had penile urethral stricture and 99 patients had bulbar urethral stricture.The length of urethral stricture was 2.8-14.0 cm,with an average of 6.4 cm.The preoperative maximal urinary flow rate Qmax was 3.2-8.4 ml/s,with an average of 4.8 ml/s.In the urethral meatal stenosis group (51 patients),15 underwent urethrotomy and 36 underwent meatal urethroplasty.In the penile urethral stricture group (174 patients),ventral sagittal incision was done in 21 patients,subcoronal circumferential incision in 49 patients and midline perineal incision in 104 patients.The perineal incision or verted Y incision were done in all the bulbar urethral strictures.Results The patients were followed-up for 3-75 months,with an average of 35.0 months.The results were satisfied in 290 (89.5％) patients.The post-operative maximal urinary flow rate Qmax was 15.8-32.2ml/s,with an average of 21.5 ml/s.Thirty-four patients (10.5％) developed recurrent urethral stricture,including 7 patients in the urethral meatus,17 patients in the penile urethra and 12 patients in the bulbar urethra.Among the recurrent urethral stricture patients,18 treated with the dilatation and 16 treated with the urethroplasty.Five patients (1.5％) developed fistula,including 2 patients in the ventral sagittal incision,1 patient in the circumferential incision and 2 patient in the perineal incision.Conclusions The long-term effect of oral mucosal urethroplasty is realistic.The rate of urethral stricture recurrence and fistula is low.The recurrence can be treated again by urethroplasty.The surgical approach for oral mucosa urethroplasty depends on the location and length of the anterior urethral stricture.
ABSTRACT
Objective To investigate the long-term efficacy of pure transanal total mesorectal excision (PtaTME) for middle-low rectal cancer.Methods The retrospective descriptive study was conducted.The clinicopathological data of 18 patients with middle-low rectal cancer who were admitted to the Sixth Affiliated Hospital of Sun Yat-sen University from July 2014 to August 2016 were collected.There were 7 males and 11 females,aged (58±13) years,with a range from 40 to 84 years.The body mass index was (22±3) kg/m2.All the 18 patients underwent PtaTME.Observation indicators:(1) surgical and postoperative conditions;(2) postoperative pathological examination;(3) follow-up and survival.Follow-up using inpatient reexamination,outpatient examination,and telephone interview were performed to detect anastomotic complications,anal function,urinary retention,sexual dysfunction,survival and tumor recurrence and metastasis once every 3 months within postoperative 6 months,once every 6 months from 6 months to 3 years,and once a year after 3 years up to June 2019.The measurement data with normal distribution were represented as Mean±SD,and the measurement data with skewed distribution were represented as M (range).Count data were expressed as percentages.Survival rates were calculated by the Kaplan-Meier method.Results (1) Surgical and postoperative conditions:18 patients successfully underwent PtaTME,without conversion to open surgery.The operation time,volume of intraoperative blood loss,distance between anastomosis and anal verge,time to first flatus,time to urinary catheter removal,and duration of postoperative hospital stay were (202±68) minutes,50 mL (range,20-400 mL),(4.5± 2.0)cm,2 days (range,2-7 days),3 days (range,2-5 days),and 7 days (range,5-10 days) in the 18 patients,respectively.There was no perioperative complication.Among 18 patients,4 underwent preventive ileostomy.(2) Postoperative pathological examinations:the length of surgical specimens,the number of lymph node dissection,distance from tumor to the distal margin were (11.0±3.0)cm,12±6,and 1.0 cm (range,0.8-3.7 cm),respectively.The 18 patients had complete mesorectal membrane excision,with negative proximal margin,distal margin,and circumferential margin.Tumor pathological staging:there were 2 cases in Tis stage,4 in T1 stage,7 in T2 stage,and 5 in T3 stage;16 in N0 stage,1 in N1 stage,and 1 in N2 stage.Tumor histological classification:2 patients had carcinoma in situ,9 had moderately differentiated adenocarcinoma,and 7 had high-differentiated adenocarcinoma.(3) Follow-up and survival:18 patients were followed up for 34.0-59.0 months,with a median follow-up time of 57.5 months.During the follow-up,4 patients developed grade B anastomotic leakage and were cured after conservative treatment.One patient developed anastomotic recurrence at 2 years after surgery,and no recurrence was found after surgical resection of the recurrent lesion.Four patients with prophylactic ileostomy had the stoma closured,and the anus function was satisfactory after surgery.There was no urinary retention or sexual dysfunction in the 18 patients.Of the 18 patients,17 had tumor free survival after surgery.The 3-year disease-free survival rate was 94.4％,and the 3-year overall survival rate was 100.0％ in 18 patients.Conclusion PtaTME can achieve high quality of specimen,which is safe and feasible for the treatment of rectal cancer.
ABSTRACT
OBJECTIVE@#To observe the efficacy and safety of electroacupuncture (EA) on improving mini-mental state examination (MMSE) in patients with Alzheimer's disease (AD), and to evaluate the efficacy during follow-up visit.@*METHODS@#Forty patients were randomly divided into a treatment group and a control group, 20 patients in each one (3 patients dropped off in the treatment group and 4 patients in the control group). The patients in the treatment group were treated with acupuncture at Baihui (GV 20), Fengfu (GV 16), Shenting (GV 24), Taiyang (EX-HN 5), Shangyintang (Extra 3) and Dazhong (KI 14); besides, EA was applied at Taiyang (EX-HN 5), Baihui (GV 20) and Shenting (GV 24) with dilatational wave, 10 Hz/50 Hz in frequency, 0.5 to 5.0 mA in intensity, once every two days, three treatments per week. The patients in the control group were treated with oral administration of donepezil hydrochloride tablets, once a day, taken before sleep. The treatment was given for 12 weeks in the two groups. The MMSE was evaluated before treatment, 12 weeks±3 days into treatment, and 24 weeks±7 days after treatment, respectively.@*RESULTS@#The difference of total score of MMSE before and 12 weeks±3 days into treatment was not significant between the two groups (>0.05); the total score of MMSE after treatment was higher than that before treatment (both <0.05); compared before treatment, the short-term memory score was increased in the treatment group (<0.05), and the increasing range was superior to that in the control group (<0.05). Compared before treatment, the total score of MMSE in the two groups were reduced 24 weeks ±7 days after treatment (both <0.05), and the reduction in the treatment group was less than that in the control group (<0.05); the differences of short-term memory score before and after treatment was significant between the two groups (<0.05). No adverse reaction occurred in the two groups.@*CONCLUSION@#The effect of EA on improving MMSE in patients with AD is similar to donepezil supported by evidence-based medicine. The effect of EA may have a certain continuous effect, and may have advantages in instantaneous memory. In addition, the EA is safe.

Purpose: The aim of the study was to analyze the outcomes of photodynamic therapy (PDT) with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for patients with polypoidal choroidal vasculopathy (PCV) having visual acuity (VA) better than 20/60 in a real-world scenario in India. Methods: Retrospective review of 42 eyes of 40 patients (mean age 64.3 years) with best-corrected VA (BCVA) 20/60 or better and mean follow-up of 40 months (median 38 months; range 12� months) treated with PDT and anti-VEGF or triamcinolone for indocyanine green angiography (ICGA)-proven subfoveal PCV. Results: Mean BCVA improved from 0.22 logMAR at baseline to 0.15 at last visit (P < 0.001). On ICGA, polyp was observed in 42 eyes (100%) and branching vascular network (BVN) in 37 eyes (88.1%). Polyp regressed in 33 (78.6%) of 42 eyes and BVN in 26 (70.3%) of 37 eyes after combined therapy at 3 months. Mean greatest linear diameter reduced significantly (P < 0.001) from 7.22 mm to 4.11 mm. Standard-fluence PDT was performed in 35 eyes and reduced-fluence in 7 eyes. The mean number of PDT was 1.17 with mean number of injections being 6.38 at the end of follow-up. In five eyes, more than one PDT was administered. Of 42 eyes, 40 showed complete resolution of serous macular detachment (SMD) after the combined therapy at 3 months; 17 (42.5%) of the 40 eyes showed no recurrence of fluid on spectral domain optical coherence tomography till the last visit with a mean follow-up of 27 months. On long-term follow-up, SMD reoccurred in 23 eyes with a mean follow-up period of 9.64 � 5.24 months. Of 38 eyes having a double-layer sign (DLS) on optical coherence tomography at baseline, 37 eyes were having regression of the DLS, that is, it either reduced or resolved at the final visit. At the final visit, 66.7% (P < 0.001) eyes were having fluid-free retina. No complication of subretinal hemorrhage was noted. Of the 42 eyes, only one eye had BCVA worse than 20/60 on the final visit. Conclusion: To the best of our knowledge, this is the first study to look into the long-term effect of combined PDT with anti-VEGF in PCV in eyes having good VA. Long-term effect of combined PDT appears to be a safe and effective treatment for PCV in eyes having good VA with better outcomes in real-world setting. This study further strengthens the superiority of the combined treatment modality for treatment of subfoveal PCV with no or minimal risk of complication on long-term follow-up.
ABSTRACT
Objective To observe the long-term clinical efficacy of intravitreal ranibizumab (IVR) in patients with idiopathic choroidal neovascularization (ICNV),and to explore the indicators that affect curative effect.Methods A retrospective self-controlled study was performed.The clinical data of 61 ICNV patients (61 eyes) from January 2013 to May 2014 in the First Affiliated Hospital of Xi'an Jiaotong University were Collected.The best corrected visual acuity (BCVA),the central retinal thickness (CRT),the height of pigment epithelium detachment (PED) and the defect length of ellipsoidal zone (EZ) before and after treatment were analyzed,the baseline clinical indicators were compared among different IVR treatment times and ICNV types.Results The mean follow-up time was (41.5±4.6) months.The mean BCVA (LogMAR) were 0.59±0.32 and 0.17 ± 0.12,the mean CRT were (331.18±80.42) μm and (245.07±44.67) μm,the mean height of PED were (246.73±104.75) μm and (205.78±117.01) μm and the mean defect length of EZ were (2 315.10± 1 233.77) μm and (1 325.98± 1 157.30) μm before and after treatment,respectively,with significant differences between before and after treatment (all at P＜0.05).Fifty-three patients (86.89％) completed the treatment in the first year or within three times.The mean CRT and the height of PED in the IVR ≥ 3 times treatment group were significantly higher than those in the IVR 1 times treatment group (all at P＜0.05).There was no significant difference in the average treatment times among inferior lateral of macular fovea,side of macular fovea and outside of macular fovea (F =1.982,P ＞ 0.05).Conclusions IVR therapy for ICNV is well tolerated with an improvement in BCVA,CRT,height of PED and defect length of EZ.The majority of patients can complete the treatment within 1 year,and most patients can be cured within 3 times treatments.The number of treatments may be associated with the CRT and the height of PED at baseline.
ABSTRACT
Objective To compare the long-term efficacy and complications of peroral endoscopic circular myotomy and full-thickness myotomy for patients with achalasia of cardia. Methods A retrospective analysis was performed on the data of 53 patients with achalasia of cardia, who underwent peroral endoscopic myotomy in the First Affiliated Hospital of Zhengzhou University from June 2012 to December 2014 and were followed-up regularly.Twenty-one patients underwent circular myotomy, and the other 32 patients underwent full-thickness myotomy. The postoperative long-term efficacy and gastroesophageal reflux complications of the two groups were compared. Results The effective rate of the circular myotomy group and the full-thickness myotomy group was 90. 5%( 19/21) and 100. 0%( 32/32), respectively ( P＝ 0. 152). There were no significant differences between the two groups on postoperative Eckardt scores, lower esophageal sphincter pressure and 4 s integrated relaxation pressure ( P ＞ 0. 05 ). The incidence of clinically relevant gastroesophageal reflux of full-thickness myotomy group was higher than that of circular myotomy group (40. 6% VS 14. 3%, χ2＝4. 174, P＝0. 041). Conclusion The long-term efficacy of circular myotomy is similar to that of full-thickness myotomy, but the incidence of clinically relevant gastroesophageal reflux is higher in full-thickness myotomy.
ABSTRACT
Objective To compare the long-term efficacy between laparoscopic liver resection and open liver resection to treat small hepatocellular carcinoma.Methods The clinical data of 52 patients with small hepatocellular carcinoma treated from August 2011 to November 2012 were reviewed.Twenty patients underwent laparoscopic liver resection (the laparoscopic group),while the remaining 32 patients underwent open liver resection (the laparotomy group).The preoperative,postoperative and overall survival data between the two groups were compared.Results The data between the two groups before surgery were comparable (all P ＞ 0.05).The differences in tumor size and pathologic type between the two groups did not reach statistical significance (t =1.087,x2 =0.738,all P ＞ 0.05).However,the length of hospital stay in the laparoscopic group was significantly shorter than in the laparotomy group (t =3.363,P ＜ 0.05).Post-procedural complications occurred in no patients in the laparoscopic group,but in 8 patients in the laparotomy group (x2 =5.909,P ＜ 0.05).The cumulative survival rates in the two groups were not statistically signifi cant (P ＞ 0.05),but the recurrence-free survival of the laparoscopic group was significantly longer than the laparotomy group (P ＜ 0.05).The postoperative 1-year disease-free survival was not significantly different (P ＞ 0.05),though the 3-and 5-year recurrence-free survival rates were significantly different (all P ＜ 0.05).Conclusion The long-term overall survival rate of laparoscopic treatment for small liver cancer was similar to open operation,but the recurrence free survival rate was greatly improved.
ABSTRACT
Objective To investigate the long-term efficacy of calcium phosphate cement combined with bFGF in repairing pulp chamber perforation and to analyze the correlation between the diameter of the perforation and the curative effect.Methods 75 patients with pulp chamber perforation (82 teeth) were enrolled and divided into the observation group and the control group according to the repair material and method.A series of subgroups were also modeled according to the diameter of the perforation,which include the control group A (≤ 1.5 mm),control group B (1.6～3 mm) and control group C (＞3 mm),as well as the observation group A (≤ 1.5 mm),observation group B (1.6～3 rmm) and observation group C (＞3 mm).The observation group was treated with calcium phosphate cement combined with bFGF,and the control group was treated with calcium phosphate cement alone.Results The total effective rate of the observation group was 97.8％,which was significant higher than 80.6％ in the control group (P＜0.05).The cure rate of the observation group A was 100％,which was significant higher than 73.3％ in the observation group B and 41.7％ in the observation group C (all P＜0.05).The total effective rates of the observation group A and B were significantly higher than 91.7％ in the observation group C (all P＜0.05).The cure rate of the control group A was 92.9％,which was significant higher than 60.0％ in the control group B and 25.0％ in the control group C (all P＜0.05).The total effective rates of the control group A (100％) and B (90.0％) were significantly higher than 91.7％ in the control group C (all P＜0.05).Conclusions Calcium phosphate cement combined with bFGF in repairing the pulp chamber perforation was significantly better than calcium phosphate cement alone.The cure rate of perforation repairing is closely related to the perforation size.The perforation with small diameter may achieve a better repairing effect.

ABSTRACT
BACKGROUND: Few studies have compared the efficacy, cosmetic outcomes, and adverse events between 5-aminolevulinic acid photodynamic therapy (ALA-PDT) and methyl aminolevulinate-PDT (MAL-PDT) for actinic keratoses (AKs) in Asian ethnic populations with dark-skin. OBJECTIVE: We retrospectively compared the long-term efficacy, recurrence rates, cosmetic outcomes, and safety of ALA-PDT versus MAL-PDT for facial AKs in Koreans. METHODS: A total of 222 facial AKs in 58 patients were included in this study. A total of 153 lesions (29 patients) were treated with 5-ALA, and 69 lesions (29 patients) with MAL. ALA and MAL creams were applied for 6 hours and 3 hours, respectively; the lesions were then illuminated with a halogen lamp at 150 J/cm2 for ALA-PDT and a diode lamp at 37 J/cm2 for MAL-PDT. RESULTS: The complete response rates of ALA-PDT and MAL-PDT were 56.9% and 50.7%, respectively, with no significant difference at 12 months after treatment. No significant difference in recurrence rates was observed between the 2 PDT modalities at either 6 or 12 months after treatment. There was no significant difference in the cosmetic outcomes between the 2 treatment modalities at 12 months after PDT. However, ALA-PDT caused significantly more painful than MAL-PDT (p=0.005). The adverse events were mild to moderate, transient, and self-limiting for both modalities. CONCLUSION: MAL-PDT was similar to ALA-PDT in terms of long-term efficacy, recurrence rates, cosmetic outcomes, and adverse events; however, it was a significantly less painful procedure than ALA-PDT in our study.

Objective To observe long-term efficacy of recombinant hepatitis B vaccines for children received fundamental immunization or booster dose. Methods 493 school students from Deqing county with complete information of immunization history were investigated and their serological markers were detected. 430 students received booster dose vaccines at 3-11 years old and were defined as booster group while the remaining 63 students were defined as fundamental group. Results All vaccines the 493 students received for fundamental immunization were recombinant. Compared with fundamental group(57. 14%),booster group had significantly higher Anti-HBs positive rate of 91. 40%(P<0. 01). And the Anti-HBs positive rate had a high level of 94. 99% when 0-5 years after booster immunization while it declined to 64. 71% after 8-15 years and showed no significant difference compared with fundamental group. Conclusion Anti-HBs level and anti -HBs positive rate can significantly increase for short periods after booster immunization,and may decline considerably for long-term. Immunologic amnesia rate is low when 3 -11 years after fundamental immunization among infants.
ABSTRACT
Objective To compare the long term efficacy of total hip arthroplasty and half hip arthroplasty in the treatment of elderly patients with femoral neck fracture .Methods 70 elderly patients with femoral neck fracture who needed hip replacement were randomly divided into the observation group and control group ,35 cases in each group.The observation group was given total hip arthroplasty ,while the control group was given half hip arthroplasty . The postoperative long term effect was compared between the two groups .Results The overall incidence rate of post-operative infection of the observation group was higher than the control group ,the postoperative revision rate of the ob-servation group was lower than the control group ,but the differences between the two groups were not statistically sig-nificant(P>0.05).The overall incidence rate of postoperative chronic pain in the control group was 22.86%,which was higher than 2.28%of the observation group,the difference was statistically significant (χ2 =5.130,P<0.05). The postoperative Harris score of the observation group was (93.25 ±4.51)points,which was significantly higher than (82.76 ±3.82)points of the control group,the difference was statistically significant (t=6.973,P<0.05).The ex-cellent and good rate of the observation group was 91.43%,which was significantly higher than 71.43%of the control group,the difference was statistically significant (χ2 =6.492,P<0.05).Conclusion Total hip arthroplasty in the treatment of femoral neck fracture can reduce the incidence of postoperative pain ,improve hip function of the patients , and its long-term effect is better than single hip replacement surgery ,which should be widely applied in clinical .
ABSTRACT
Objective To evaluate the efficacy and safety of Haijiyi under nasal endoscope in the treatment of allergic rhinitis(AR).Methods 213 cases with AR were randomly divided into treatment group(112 cases) and control group(101 cases).Patients in the treatment group were treated with Haijiyi under nasal endoscope.The control group was treated with traditional microwave therapeutic equipment.Both two groups were followed up for 1 year,and long-term clinical efficacy was observed and compared between the two groups.Results The total effective rate of the treatment group was 80.4％,which was higher than 61.4％ of the control group,and the difference was statistically significant(P＜ 0.01).Conclusion Haijiyi CZB type in the treatment of AR has advantages of exact allocation,no bleeding,less complication,good long-term efficacy,which is worth clinical popularizing and application.
ABSTRACT
Objective To investigate the management of iatrogenic bile duct injury and evaluate the longterm efficacy.Methods The clinical data of 62 patients with iatrogenic bile duct injury who were admitted to the Peking Union Hospital from January 1982 to April 2012 were retrospectively analyzed.Of the 62 cases of iatrogenic bile duct injuries,24 were caused by laparoscopic cholecystectomy (LC) and 38 were caused by open cholecystectomy. Ten patients received non-surgical treatment, including 8 patients received percutaneous transhepatic cholangiography and drainage (PTCD) and 2 received endoscopic retrograde cholangiopancreatography (ERCP) + stent implantation. Fifty-two patients received surgical treatment,including 47 received cholecystojejunostomy,2 received cholecystoduodenostomy,3 received biliary end-to-end anastomosis. Thirty-six patients received PTCD preoperatively,and 42 received biliary stent implantation intraoperatively.Fifty patients received intraoperative peritoneal drainage to prevent postoperative peritoneal effusion or encapsulated bile collection.Results Of the 52 patients who received surgery,13 patients were complicated by more than 1 complication,including 1 case of wound infection,4 cases of cholangitis,2 cases of anastomotic leakage,2 cases of anastomotic bleeding,1 case of anastomotic occlusion, 1 case of biliary stent falling out and 3 cases of gastrointestinal diseases.Eighteen patients received cholangiography postoperatively,and 2 patients were diagnosed as with bile leakage.Fifteen patients received PTCD + biliary stent implantation,and 1 patient of them received percutaneous puncture drainage.Two patients received reoperation due to anastomotic bleeding.The mean time of peritoneal drainage for the 50 patients was (7.7 ± 2.6) days.No perioperative death was observed,and the mean operation time was (18 ± 12) days.Fifty-five patients were followed up (10 patients received non-surgical treatment,and 45 patients received surgical treatment),with a median time of 93 months.Of the 10 patients who received nonsurgical treatment,1 received reoperation due to bile leakage,3 received PTCD for the second time due to repeated cholangitis after PTCD. Of the 45 patients who received surgical treatment,6 patients had long-term complications,including 6 cases of fever,4 cases of jaundice,3 cases of choledocho-lithiasis and 1 case of bile duct canceration; 4 received reoperation at the second year after operation.Conclusions Early diagnosis of bile duct injury and operation carried out by experienced surgeons are important for a better short- and long-term prognosis.Surgical repair is the first line therapy for bile duct injury.
