Objective:To evaluate the effectiveness and safety of phacoemulsification cataract extraction combined with intraocular lens implantation (PEI) plus goniosynechilysis (GSL) and goniotomy (GT) for advanced primary angle-closure glaucoma (PACG).Methods:An observational case series study was performed.Fifty eyes of 50 patients with advanced PACG were enrolled in Zhongshan Ophthalmic Center from August 2020 to June 2021.All the patients received PEI+ GSL+ GT and were followed up for over 6 months, with a mean follow-up of 7.5 (6, 10) months.Intraocular pressure (IOP) was measured with a Goldmann applanation tonometer.Best corrected visual acuity (BCVA) was examined with an ETDRS chart and converted to logarithm of the minimum angle of resolution (LogMAR) units for analysis.Types and number of anti-glaucoma medications applied before and after surgery, and the surgical complications were collected.Success rate of surgery was calculated.Complete surgical success was defined as an IOP of 5-18 mmHg (1 mmHg=0.133 kPa) with a reduction of 20% from baseline without anti-glaucoma medication, no vision-threatening complications, no loss of light perception, and no reoperation.Qualified success was defined as an IOP of 5-18 mmHg with a reduction of 20% from baseline with or without anti-glaucoma medication, no vision-threatening complications, no loss of light perception, and no reoperation.This study adhered to the Declaration of Helsinki.This research protocol was approved by an Ethics Committee of Zhongshan Ophthalmic Center (No.2021KYPJ177). Written informed consent was obtained from each subject before entering the cohort.Results:The mean preoperative IOP was (28.81±7.81)mmHg, and the IOP at the end of follow-up was (13.41±4.10)mmHg, showing a statistically significant decrease ( t=12.260, P<0.001). The postoperative IOP was decreased by 13.80 (9.10, 19.40)mmHg, with a percentage decrease of 51.1% (38.6%, 67.1%). The mean preoperative and postoperative BCVA was (0.92±0.11) LogMAR and (0.88±0.10) LogMAR, respectively, and no significant difference was found ( t=-0.560, P=0.580). The number of anti-glaucoma medications was reduced from 2 (1, 3) before operation to 0 (0, 0) after operation.The complete success rate of surgery was 80% (40/50), and the qualified success rate was 94% (47/50). Surgical complications mainly included hyphema in 7 eyes, IOP spike in 7 eyes, and corneal edema in 3 eyes.No vision-threatening complication occurred. Conclusions:PEI+ GSL+ GT is preliminarily effective and safe for advanced PACG by reducing IOP and application of anti-glaucoma medications with few complications.

Objective:To explore the clinical application value of 3D printing technology in percutaneous nephrolithotomy(PCNL) to complex renal calculi.Methods:The clinical data of 41 patients with complex renal calculi from May 2018 to October 2019, in the First Affiliated Hospital of Xiamen University and Xiang'an District of the First Affiliated Hospital of Xiamen University were retrospectively analyzed. There were 19 cases underwent PCNL after 3D printing (3D printing group), and 22 cases during the same period did not undergo 3D printing before operation (control group). Before operation, the two groups underwent CT plain scan enhanced examination. In 3D printing group, 3D printing technology was used to obtain 3D renal models, then 3D renal models were used for preoperative design and simulation of surgical puncture and preoperative conversation.The control group only underwent PCNL after routine examination.The ages of the patients in 3D printing group and control group were (42.9±2.5) vs. (41.3±2.9) years old, male/female ratio 11/8 vs. 12/10, body mass index (22.4±1.1) vs. (23.2±1.4) kg/m 2, serum creatinine (42.9±2.5) vs. (78.2±4.5) μmol/L, stone size (5.0±1.2) vs. (5.2±1.3) cm, the CT values of the stones was (930±210) vs.(950±200) HU. The difference of above parameters was not statistically significant ( P>0.05). The following indexes were compared between the two groups: score of questionnaire on satisfaction of preoperative conversation, and datas about operation and postopetation. Results:All the operations were successfully completed. The time of locating the target calyces in 3D printing group and control group was (3.3±1.3) vs. (5.3±3.1) min, and the coincidence of puncture calices was 94.7% (18/19) vs. 54.5%(12/22), and the stone removal rate of the 3D printing group was 78.9% (17/19) vs. 36.4% (8/22), 3D printing group was better than the control group in these respects( P < 0.05). However, there were no significant differences in postoperative complications [21.0% (4/19) vs. 13.6% (3/22)], multi-channel[89.4% (17/19) vs. 86.4% (19/22)], operation time [(121.8±20.2) vs. (132.1±18.5) min], time of hospitalization [(7.6±1.3) vs. (8.0±1.8)d] and time of extubation for renal fistula [(3.8±1.7)vs. (4.5±2.0 )d] (all P > 0.05). During preoperative conversation between the 3D printing group and the control group , the time spent on signing the consent [(17.0±3.9) vs.(21.0±3.3) min], the degree of understanding of the stone condition [(2.5±0.6)vs.(2.0±1.2) points], the degree of understanding of the PCNL surgical process and complications [(2.6±0.6) vs.(1.8±1.3) points] and the degree of satisfaction with the doctor’s preoperative conversation effects [(2.4±0.9) vs.(1.7±1.6) points]were significantly different in comparisons ( P<0.05). Conclusions:3D printing technology can be used in PCNL to directly display the internal anatomical relationship of renal calculi, guide accurate preoperative designing, help improve the operation efficiency and stone clearance rate, and can also be used as a mold in preoperative conversation to improve communication efficiency.

Objective:To describe and analyze the clinical manifestations of patients with orofacial pain of temporomandibular disorders (TMD).Methods:A retrospective study on orofacial pain was conducted for 3 425 patients diagnosed as TMD based on clinical symptoms and signs in the Department of Temporomandibular Disorders and Orofacial Pain, School of Stomatology, The Fourth Military Medical University. The patients included 1 158 males and 2 267 females with a median age of 32 years. The gender, age, course of disorders, pattern and site of pain, CT imaging diagnosis of temporomandibular joint (TMJ) were analyzed. The distribution of gender, age and disorder course interval were described. The differences in frequency of the pattern and site of pain, imaging diagnosis in different gender, age and disease course interval were compared. Chi-square test and non-parametric rank sum test were performed using software SPSS 23.0.Results:Of the 3 425 patients, 29.1% (997/3 245) had signs of joint popping, and 40.1% (1 373/3 425) had restricted opening. The pain frequency was higher in males who had disorder course less than 1 month ( P<0.01) and also in males who had open-and-close and/or lateral excursion and/or protrusion pain without tenderness or other pain without tenderness ( P<0.05). However, the pain frequency was higher in females who had tenderness ( P<0.01). The pain frequencies in those over 56 years old with tenderness combined with open-and-close and/or lateral excursion and/or protrusion pain were higher than in patients of other ages ( P<0.01). In patients with unilateral TMJ pain, the frequency in males was higher than females( P<0.01), while the frequency in females was higher in patients with unilateral TMJ pain combined with unilateral or bilateral myalgia and the frequency was higher in patients under 15 years old having bilateral TMJ pain and/or unilateral or bilateral myalgia ( P<0.05). In patients with unilateral TMJ pain, the frequency in those with disorder course≤1 month was higher than in those with other disease duration intervals ( P<0.01), while in patients with bilateral myalgia or TMJ pain plus unilateral or bilateral myalgia, the frequency in those with disorder course>3 years was higher than in those with other disease duration intervals( P<0.01). In patients with unilateral TMJ pain, the frequency was higher in those having open-and-close and/or lateral excursion and/or protrusion pain ( P<0.01). In patients with unilateral myalgia and bilateral myalgia, the frequency was higher in those having tenderness ( P<0.01). The frequency of TMJ space changes in male patients was higher than females and the frequency of hyperosteogeny and resorption in females were higher than males ( P<0.05). The frequency of TMJ space changes and developmental problems were higher in patients aged 16 to 35 years, while the frequencies of hyperosteogeny, bone resorption and cystis in those over 56 years were higher than other ages ( P<0.01). The frequency of TMJ space changes in patients with disorder course≤1 month was higher than in those with other disease duration intervals ( P<0.01), while the frequency of hyperosteogeny was higher in patients with disorder course>3 years ( P<0.01). Conclusions:The male to female ratio in the present patients with orofacial pain of TMD was about 1 to 2. Most of the patients visited hospital within half a year after the disorders occurred. The pattern and site of the orofacial pain, signs on TMJ CT images showed some distribution regularities in views of gender, age and disorder course.

Objective:To evaluate the clinical efficacy of Sini-Jia-Huanglian Decoction on chronic heart failure (CHF) with qi deficiency and blood stasis syndrome. Methods:A total of 100 patients with CHF and qi deficiency and blood stasis syndrome in Handan Mingren hospital from January 2018 to June 2019 who met the inclusion criteria were divided into two groups according to the random number table method, 50 cases in each group. The control group was treated with conventional western medicine therapy, and the treatment group was treated with Sini-Jia-Huanglian Decoction on the basis of the control group. Both groups were treated for 30 days. TCM syndrome score was performed before and after treatment. The level of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) was detected by radioimmunoassay. The levels of peptide and galectin 3 (Gal-3) were detected by ELISA. The exercise tolerance was measured by 6-minute walking test, the clinical efficacy was tevaluated. Results:The total effective rate of the treatment group was 92.0% (46/50), and the control group was 76.0% (38/50), there was significant difference between the two groups ( χ2=4.762, P=0.029). After treatment, the scores of shortness of breath, palpitation, dyspnea, dizziness, chest pain and total scores in the treatment group were significantly lower than those in the control group ( t values were 4.257, 8.493, 8.211, 4.481, 5.500, 6.977, respectively, all Ps<0.01). After treatment, the levels of NT-proBNP (2 349.61 ± 683.50 ng/L vs. 3 026.27 ± 714.35 ng/L, t=4.840), and peptide (12.16 ± 3.43 ng/L vs. 17.52 ± 3.98 ng/L, t=7.214) and Gal-3 (3.01 ± 0.82 μg/L vs. 3.94 ± 0.93 μg/L, t=5.304) in the treatment group were significantly lower than those in the control group ( P<0.01), and the walking distance of 6 minutes (450.66 ± 79.25 m vs. 384.49 ± 70.16 m, t=4.421) was significantly longer than that of the control group ( P<0.01). Conclusions:The Sini-Jia-Huanglian Decoction can improve the heart function and clinical symptoms of CHF patients with qi deficiency and blood stasis syndrome, and improve the clinical efficacy.

Objective:To explore the clinical characteristics and outcomes of pediatric kidney transplantations at a single center and discuss the related clinical issues.Methods:From January 1990 to October 2019, clinical data were analyzed retrospectively for 244 pediatric renal transplants. The youngest recipient was aged 1.8 years and the median age of pediatric recipients was 12.2 years. The major disease was primary or hereditary glomerulonephritis ( n=160, 69.0%), congenital anomalies of kidney and urinary tract (CAKUT), cystic renopathy and other hereditary nephropathies ( n=55, 23.7%). The donor sources included traditional deceased donor ( n=42, 17.2%), living-related donor ( n=19, 7.8%) and organ donation ( n=183, 75.0%). The median age of donors was 2 years (0-51) and the median weight 12.0(2.7-72.0) kg. From January 2013 to October 2019, 170 cases), the major induction immunosuppression regimen was anti-thymocyte globulin (ATG) ( n=110, 64.7%) or basiliximab ( n=58, 34.1%). The maintenance regimen was tacrolimus + mycophenolic acid (MPA) + glucocorticosteroids. Finally the outcomes and the complications were analyzed. Results:The survival rates of 244 kidney allograft recipients were 98.1%, 94.5% and 93.4% and the graft survival rates 92.6%, 84.2% and 82.0% at 1/3/5 years respectively. Ten recipients died of accident ( n=2, 20.0%), pneumonia after transplantation ( n=2, 20.0%) and intracranial hemorrhage ( n=2, 20.0%). Thirty-three recipients lost their allografts mainly due to intravascular thrombosis in graft ( n=5, 14.3%), acute rejection ( n=5, 14.3%) and death ( n=9, 25.7%). Besides, among 109 deceased donor allograft recipients, the postoperative outcomes were delayed graft function recovery (DGF) ( n=27, 24.8%), arterial thrombosis ( n=6, 5.5%), venous thrombosis ( n=1, 0.9%), graft perirenal hematoma ( n=6, 5.5%), raft artery stenosis ( n=10, 9.2%) and graft ureteral fistula ( n=1, 0.9%). The incidence of acute rejection was 17.5% and 23.2% at 1/3 year respectively. The recurrent rate of primary disease was 6.9%, including primary FSGS ( n=3, 42.9%) and IgA nephropathy ( n=2, 28.6%). At 1/3 year post-operation, the incidence of pulmonary infection was 16.9% and 22.4% and the incidence of urinary tract infection 26.9% and 31.7%. Excluding recipients with graft failure, the estimated glomerular filtration rate (eGFR) at 1/2/3 year postoperatively was (80.3±25.2), (81.4±27.8) and (71.8±27.6) ml/(min·1.73 m 2)respectively. Conclusions:The outcomes of pediatric renal transplantations are excellent at our center. Future efforts shall be devoted to optimizing the strategies of donor kidney selection and strengthening preoperative evaluations, perioperative and postoperative managements for improving the long-term outcomes of pediatric renal transplantations.

Objective To explore the impact of glucocorticoid on coagulation through administrating on rats with smoke inhalation.Methods Totally 150 male S-D rats were randomly (random number) divided into 5 groups:control group (ambient air inhalation),smoke group (smoke inhalation for 30 min),smoke+high dosage methyl prednisolone group(MP 40 mg/kg,intraperitoneal injection,s+HMP group),smoke+medium dosage MP (4 mg/kg) group (s+MMP group),smoke+low dosage MP (0.4 mg/kg) group (s+LMP group) (all n=30).Survival rates were calculated 24 h after smoke inhalation.Lung tissues were collected for histopathology and wet to dry (W/D) ratio.Arterial blood was collected for blood gas test.Coagulation factors in lung and plasma were tested.Results Survival rates of three MP groups were markedly improved compared with the smoke group (all P＜0.05),and was significantly higher in the medium dosage group(85.17％) than those in the low and high dosage groups (65.73％ and 60.07％,all P＜0.05).The W/D ratio and blood gas test were markedly improved in the high and medium groups (all P＜0.05).Tissue factor (TF) and thrombin-antithrombin complex (TAT-c) in bronchoalveolar lavage fluid (BALF) increased dramatically after SI (P＜0.01,P=0.005) with a remarkable drop of factor Ⅱ (F Ⅱ) (P=0.007),all of which were attenuated by MP with dosage dependence.The mRNA expression of TF increased dramatically after SI and recovered significantly with MP administration,while the expression of thrombomodulin (TM) recovered in the opposite direction with MP,all of which were in a dosage dependent manner.TF,fibrinogen (FIB),TAT-c increased significantly in plasma after smoke inhalation (P＜0.01,P=0.027,P=0.005).F Ⅷ ％ increased with MP administration and TF was raised by high dosage MP compared with the smoke group.FIB and TAT-c were decreased in all MP groups,which were significant higher in the high and middle dosage groups.The change of TM and endothelial cell protein C receptor (EPCR) in circulation were similar with FIB or TAT-c with or without MP.Protein C (PC％) and antithrombin (AT Ⅲ ％) dropped dramatically after SI,high and middle dosages of MP could restore the activity significantly,while low dosage would restore AT Ⅲ ％ but not PC％.Conclusions Glucocorticoid can significantly improve local and systemical coagulation disorder caused by smoke inhalation,and high-and medium-dosage hormones are effective.The regulation of hormones on the coagulation system is an important mechanism in the treatment of smoke inhalation induced lung injury.

Objective: To investigate the effect of perioperative fluid therapy on early postoperative pulmonary complication (PPC) after orthotopic liver transplantation (OLT). Methods: The clinical data of 132 patients who underwent OLT in the First Affiliated Hospital of Xi′an Jiaotong University from April 2016 to December 2017 were analyzed retrospectively. These patients included 96 males and 36 females, aged (47.3±9.6) years (range: 24-69 years). Based on the clinical manifestations, laboratory and imaging findings of patients in ICU and PPC occurrence within 7 days after OLT surgery, the patients were divided into 2 groups: non-PPC group and PPC group. Univariate and multivariate logistic regression analyses were used to evaluate the association between perioperative variables and PPC. The Kaplan-Meier method was used to estimate cumulative survival of recipients with or without PPC within 2-years. Results: During the follow-up, 11 patients (8.3%) died and 72 patients (54.5%) developed PPC after operation. There were 34 cases, 6 cases, 3 cases, 4 cases, 15 cases, 6 cases and 4 cases of only pleural effusion, only pulmonary edema, only pneumonia, pleural effusion with pneumonia, pleural effusion with pulmonary edema, pleural effusion with atelectasis, and pleural effusion with pneumonia and pneumonia in PPC, respectively. Univariate analysis showed that the preoperative factors (model for end-stage liver disease score), the intra-operative factors (duration of surgery, total infusion volume, total blood products) and the postoperative cumulative fluid balance within the first 24 h, 48 h, and 72 h were the prognosis factors of PPC (P<0.05). At least two out of the first three postoperative days with a fluid balance of ≤-500 ml was a protective factor. Using multivariate analysis by Logistic regression, only the red blood units >10 U (OR=3.55, 95% CI: 1.35-9.26, P=0.010) and the cumulative fluid intake >12 L (OR=2.98, 95% CI: 1.14-7.80, P=0.026) within the first 72 h after operation were independent prognosis factors of PPC after OLT. Kaplan-Meier analysis showed that the cumulative survival rate was lower in PPC group than that in non-PPC group (χ²=6.590, P=0.01). Conclusion Massive red blood cell transfusion and the cumulative fluid volume >12 L during perioperative 72 hours are independent prognosis factors of PPC after OLT.

Objective: To explore the clinical and prognostic features of lipoprotein glomerulopathy (LPG) in renal allografts. Methods: Retrospective analysis was performed for two case of LPG in renal allografts. The onset time was 6 and 9 years after living transplantation respectively. Initial symptoms included proteinuria and hypoproteinemia. Color Doppler ultrasound showed an enlarged graft size and greater parenchymal echogenicity. One patient had hyperlipemia and elevated apolipoprotein E (ApoE). Methylprednisolone pulse was offered with an early control of hyperlipidaemia and proteinuria by fenofibrate and angiotensin-converting enzyme inhibitors (ACEIs). Yet it had no effect on graft function. The definite diagnosis was made by graft biopsy. Pathological examination indicated non-homogeneous lipid deposition in glomerular capillary, glomerular sclerosis, mesangial hypercellularity and tubular atrophy. Results: During a follow-up period of 8 and 10 years post-transplantation, two cases eventually lost their grafts within 2 and 1 year after biopsy respectively. With long-term dietary control and drug therapy, regular dialysis continued and both awaited a second transplantation. Conclusions LPG is generally steroid-resistant and refractory in renal allografts. And routine biopsy is recommended for patients with a high risk of occurrence. Early controls of hyperlipemia and hypoproteinemia and other risk factors should be also properly managed.

Objective To explore the clinical outcome of renal transplantation and analyze the risk factors influencing the kidney allograft survival after transplantation.Methods The clinical data of 524 cases of renal transplantation between January 2007 and December 2015 were retrospectively analyzed.Serum creatinine was determined,and glomerular filtration rate(GFR) was estimated.The 1-,2-and 3-year patient and graft survival after transplantation was calculated.Adverse events were recorded.Results The median follow-up time was 17.2 months.The 1-,2-and 3-year graft survival rate after transplantation was 97％,95.8％ and 95.3％,respectively.The 1-,2-and 3-year patient survival rate after transplantation was 97.8％,97％ and 97％,respectively.The eGFR was (67.6 ± 24.1),(68.9±24.2) and (72.7 ± 26.2) ml·min-1 ·1.73 m-2 at 1st,2nd and 3rd year after transplantation.The incidence of delayed graft function(DGF) was 20.6％ (108/524).Multivariate analysis revealed donor type (P =0.005) and the terminal creatinine (P＜0.001) were the independent risk factors of DGF.Elder recipients (P =0.004),recipients with diabetes(P =0.031),preoperative positivity of panel reactive antibody(PRA) (P =0.023),and donor with hypertension (P =0.046) were risk factors influencing the kidney allograft survival.Conclusion Kidney transplantation showed good outcomes at 3rd year after transplantation.The recipient age,recipient's history of diabetes,preoperative PRA and donor's history of hypertension are independent risk factors for renal graft survival.

Objective: This paper discusses a surgical method to improve the middle part of face and the temporal surface by using the patented technology of embedding guidance technology. Methods: On the basis of not removing the skin, the application of embedding guidance technology was applied to achieve the effect of facial lifting by placing a 2-0 polyester knitting line under the scalp with a minimally invasive incision(3-5 mm) , paving up to the skull periosteum and down to the hairline edge for compound fixation. Results: Among the 200 patients, 197 were female and 3 were male. Aging from 23-62 years old, all of the patients suffered from mild to moderate problem of saggy skin.Post-operation follow-up was kept from 3 months to 5 years after the treatment, which demonstrated that all of the patients showed different degrees of facial lifting after edema subsided at 3 months, including improvedfacial skin condition, shallower nasolabial groove, lifting of the lateral canthus and tightening of facial skin. The patients were satisfied with the effect. Conclusions The surgical method is an effective method to solve the problem of facial aging with advantages, such as simple execution, minimized wound, fast recovery, no post-operation bandage requirement and showing great result towards patients suffering from mild and moderate saggy facial skin problem.
