ObjectiveTo observe the differences of horizontal optic disc diameter and cup/disc (C/D) ratio in eyes with different kinds of retinal vein occlusion (RVO). MethodsA total of 392 eyes from 385 RVO patients diagnosed by fundus fluorescein angiography (FFA) were included in this study. The patients included 192 males and 193 females. The average age was (58.30±11.51) years. The disease duration was from 7 days to 1 month. The eyes were divided into RVO group (356 eyes), RVO combining diabetes mellitus (DM) group (20 eyes) and RVO combining high blood pressure (HP) group (16 eyes). One hundred normal eyes examined by FFA in the same testing period were selected as the control group. Among the 356 eyes in the RVO group, there were 201 eyes with branch RVO (BRVO), 100 eyes with central RVO (CRVO), 17 eyes with hemi CRVO (H-CRVO), and 38 eyes with macular BRVO (M-BRVO). Among the 101 non-ischemic RVO eyes, there were 17 eyes with BRVO, 53 eyes with CRVO, 6 eyes with H-CRVO, and 25 eyes with M-BRVO. Among the 255 ischemic RVO eyes, there were 184 eyes with BRVO, 47 eyes with CRVO, 11 eyes with H-CRVO and 13 eyes with M-BRVO. The diameter of optic cup and disk, and the C/D ratio was measured on fundus infrared radiation (IR) IR30°image by Heidelberg confocal laser fundus imaging system. ResultsThere was no significant difference of horizontal optic disc diameter among 4 groups (F=1.17, P>0.05). The difference of C/D ratio was significant among 4 groups (F=82.24, P<0.05). The differences of horizontal optic disc diameter and C/D ratio in different kinds of RVO in normal group and RVO group were significant (F=4.49, 61.396; P<0.05). The horizontal optic disc diameter of eyes with CRVO was a little smaller than normal eyes (P<0.05). There was no difference of horizontal optic disc diameter between the eyes with BRVO, M-BRVO, H-CRVO and normal eyes (P>0.05). The difference of C/D ratio was significant between the eyes with BRVO, CRVO, M-BRVO, H-CRVO and normal eyes (P<0.05). The differences of horizontal optic disc diameter and C/D ratio were significant between RVO group (in different kinds of RVO eyes) and control group (F=3.94, 33.16; P<0.05). Compared the horizontal optic disc diameters of RVO eyes with the same subtype, the difference was significant between non-ischemic H-CRVO and ischemic H-CRVO (P<0.05), while the differences were not significant between other non-ischemic RVO and ischemic CRVO (BRVO:P=0.35,CRVO:P=0.86,M-BRVO:P=0.22). The difference of C/D ratio between non-ischemic RVO and ischemic CRVO was not significant (BRVO:P=0.35,CRVO:P=0.48,H-CRVO:P=1.00,M-BRVO:P=1.00). ConclusionsThe C/D ratio increased with varying degrees in RVO eyes. There is no obvious change in horizontal optic disc diameters except for CRVO eyes.
ObjectiveTo analyze the correlations between the immune function and inflammatory factors levels of patients with hepatocellular carcinoma (HCC) and the results of in vitro high-throughput drug sensitivity, and to provide a reference for personalized drug selection for patients with HCC. MethodsThe patients with HCC who met the inclusion criteria from December 2019 to June 2021 in the First Affiliated Hospital of Chongqing Medical University were included. The HCC cells were used to perform in vitro high-throughput drug sensitivity screening, the result was classified into sensitive and insensitive. The correlations between drug sensitivity results and immune function and inflammatory factors levels of corresponding patients were analyzed, and the relation between these indexes (P<0.05) and drug sensitivity of HCC cells to drugs or combination regimen of drugs was further analyzed by univariate logistic regression. ResultsA total of 74 patients with HCC were included in this study. The results showed that the level of interleukin-6 was negatively correlated with sorafenib, caffezomib, gemcitabine, oxaliplatin + epirubicin + irinotecan + 5-fluorouracil, oxaliplatin + irinotecan + epirubicin, and oxaliplatin + epirubicin regimens on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with bortezomib (P<0.05). However, the level of interleukin-6 was not related to the sensitivity of HCC cells to these single drugs or combined regimens (P>0.05). Meanwhile it was found that tumor necrosis factor (TNF)-α was negatively correlated with cabotinib, apatinib, caffezomib, and epirubicin on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with epirubicin (P<0.05). But only it was found that tumor necrosis factor-α level was related to the sensitivity of HCC cells to epirubicin (P<0.05). ConclusionsTumor necrosis factor-α level in peripheral blood of patients with HCC has a certain relation with epirubicin on inhibition rate of HCC in vitro and it might have a certain value in predicting sensitivity of HCC cells to epirubicin. Meanwhile, although it is found that level of IL-6 is related to sorafenib, caffezomib, gemcitabine, or including combination regiems including oxaliplatin and epirubicin on inhibition rates of HCC in vitro, their value is not found in predicting sensitivity of HCC cells to these single drugs or combined regimens.

ObjectiveTo explore the short- and mid-term effectivenesses of combined unicompartmental knee arthroplasty (UKA) and anterior cruciate ligament (ACL) reconstruction for osteoarthritis (OA) and ACL injury. MethodsBetween January 2006 and January 2014, 32 patients with knee OA and ACL injury were treated by combined UKA and ACL reconstruction. There were 12 males and 20 females, aged 41-63 years (mean, 50 years); 17 left knees and 15 right knees were involved. The causes of ACL injury were sports injury (25 cases) and traffic accident injury (7 cases), including 27 cases of old injury and 5 cases of acute injury. Pain of the medial compartment of the knee and unstable knee joint were the main clinical symptoms. Preoperative X-ray films showed (3.1±0.6)° of varus deformity. ResultsAll incisions healed by first intention, without complication. The patients were followed up 16-112 months (mean, 55 months). Mobile bearing dislocation occurred in 2 cases after operation, and was cured after replacing much thicker mobile bearings. X-ray films showed (4.0±0.7)° of valgus at last follow-up. There was no loosening of the prosthesis. Physiological radiolucent line (<1 mm) was observed around the tibial component in 10 patients. The Oxford Knee Score (OKS), Knee Society Score (KSS) clinical score, KSS functional score, and Tegner activity score at last follow-up were improved significantly (P<0.05). The range of motion (ROM) of the operated knee was (123.5±2.8)°, and the posterior slope of the tibial component was (3.9±1.2)° at last follow-up; a significant correlation was found between ROM and posterior slope according to the Pearson's correlation (r=0.392, P=0.031). ConclusionCombined UKA and ACL reconstruction has good short- and mid-term effectivenesses for OA and ACL injury.
Objective To compare the early effectiveness between SuperPATH approach and traditional Hardinge approach in total hip arthroplasty (THA). Methods Between May 2015 and March 2016, 154 patients (173 hips) undergoing initial THA were included. THA was performed by SuperPATH approach in 64 cases (70 hips) in group A and by traditional Hardinge approach in 90 cases (103 hips) in group B. There was no significant difference in gender, age, body mass index, type of disease, and Harris hip score (HHS) between 2 groups (P>0.05). The incision length, operation time, intraoperative blood loss, postoperative drainage volume, transfusion rate, ambulation time, length of stay, and complications were recorded. The HHS and visual analogue scale (VAS) were compared between 2 groups before operation and at 1 day, 3 days, 1 week, 3 weeks, 6 weeks, 12 weeks, and 24 weeks after operation. And the relative parameters were measured for imaging evaluation of prosthesis position. In addition, the stratification analysis was performed on 92 patients (100 hips) who received the SuperPATH technology. Results The incision length, ambulation time, and length of stay in group A were significantly less than those in group B (P<0.05); the operation time, transfusion rate, and intraoperative blood loss of group A were significantly higher than those of group B (P<0.05); and there was no significant difference in postoperative drainage volume between 2 groups (t=1.901,P=0.071). The follow-up period was 6 to 15 months (mean, 9 months). The VAS scores at 1 day, 3 days, and 1 week after operation in group A were significantly lower than those in group B (P<0.05), but the HHS scores at 1 day, 3 days, 1 week, and 3 weeks after operation in group A were significantly higher than those in group B (P<0.05). At 24 weeks after operation, the acetabular cup abduction and the proportion within the safe zone showed no significant difference between 2 groups (P>0.05); the anteversion angle and limb length difference in group A were significantly greater than those in group B (P<0.05), and the proportion of anteversion angle within the safe zone and eccentricity and recovery rate were significantly lower than those in group B (P<0.05). In the stratification analysis, the operation time, incision length, intraoperative blood loss, transfusion rate, and VAS score at 1 day after operation in the former 30 hips were significantly higher than those in the latter 70 hips (P<0.05). Great trochantern fracture and dislocation of the hip joint occurred in 1 and 2 of the former 30 hips, but no complications occurred in the latter 70 hips. No injury of nerve or blood vessel, deep vein thrombosis, infection, and prosthetic loosening were observed in the 2 groups. Conclusion Compared with the Hardinge approach, the SuperPATH approach shows the advantages in little trauma, fast recovery, satisfactory effectiveness, and slight early postoperative pain, but it shows the disadvantages of much intraoperative blood loss and long operation time. In addition, SuperPATH approach needs a more anteverted angle, a smaller eccentricity, and a learning curve, so the mid-term and long-term outcomes still need further follow-up study.
