objective To compare the surgical effect of short median incision approach and mini-incision approach in patients with medial unicompartmental knee arthroplasty.Methods A total of 65 patients with knee medial compartment osteoarthritis were treated with Oxford third-generation artificial unicondylar joint from April 2012 to July 2016 in PLA 960 hospital were enrolled.Among them,31 patients were treated with mini-incision approach and 34 patients were treated with short median incision approach.The postoperative incision healing and follow-up status of patients in the two groups were compared.The operating time of two incision approaches was counted,and the total blood loss during and after operation were calculated by Gross equation.The time to get out of bed after operation,the visual analogue scale(VAS)scores before operation,1 day after operation,1 week after operation and 1 month after operation,and the hospital for special surgery(HSS)scores before operation,1 month after operation,3 months after operation and at the last follow-up were counted.Results Three patients with previous diabetes had delayed incision healing after surgery,one patient in the mini-incision group suffered pad dislocation 6 months after operation,and three patients died of other medical diseases within 3 years after operation.The 5-year survival rate of the prosthesis was 93.85%.In the mini-incision group,the average preoperative muscle strength of quadriceps femoris was(3.10±0.60)level,and the average postoperative time to get out of bed was(1.32±0.35)days;In the short median incision group,the average preoperative muscle strength of quadriceps femoris was(3.18±0.63)level,and the average postoperative time to get out of bed was(1.37±0.41)days.There was no statistically significant difference in the postoperative time to get out of bed,operation time,total blood loss during and after operation,VAS score,HSS score of patients between the two groups(P>0.05).Conclusion The short median incision approach and mini-incision approach for unicompartmental knee arthroplasty have similar clinical effects.The short median incision approach has clearer exposure during operation,and the patellofemoral joint can be better treated,which provides conditions for modifying the surgery;the mini-incision approach is highly accepted by patients and minimizes soft tissue damage.Both of them have their own advantages.

Objective To observe the course and diameter of facial artery branches and its adjacent structures in nasolabial groove area and the positional relationship,so as to provide reference for clinicians to carry out facial cosmetic repair surgery.Methods A total of 40 adult head and neck specimens were dissected on the spot,and the course and position of the facial artery branches,facial vein and facial nerve in the nasolabial groove area were observed,their diameters were measured,and relevant data were recorded.Results There were 4 types of facial artery branches in the nasolabial groove area:type Ⅰ(upper lip type)accounted for 12.5%,type Ⅱ(nasal type)accounted for 62.5%,type Ⅲ(classical type)accounted for 20.0%,and type Ⅳ(double severe type)accounted for 5.0% .There were 4 kinds of positional relationship between the facial artery and the facial vein in the nasolabial groove area:42.5% of the orofacial artery was located on the medial side of the facial vein,32.5% of the orofacial artery was located on the lateral side of the facial vein,17.5% of the two were close to and wrapped in a fascial sheath,7.5% of the orofacial artery and the main trunk of the facial vein were crossed,and the vein was located in the deep surface of the artery.There were 3 kinds of positional relationship between the facial artery and the marginal mandibular branch of the facial nerve:87.5% of the facial artery was deep on the marginal mandibular branch of the facial nerve,7.5% of the facial artery was superficial on the marginal mandibular branch of the facial nerve,and 5.0% of the facial artery was held or surrounded by two branches of the marginal mandibular branch of the facial nerve on the superficial or deep surface.Conclusion The positional relationship among facial artery,facial vein and facial nerve in the nasolabial groove area is complicated.Familiarity with its positional relationship can avoid damaging blood vessels and nerves during the nasorabial groove surgery,reduce surgical complications and improve surgical safety.

BACKGROUND: Controversy exists as to the optimal treatment approach for ostial left anterior descending (LAD) or ostial left circumflex artery (LCx) lesions. Drug-coated balloons (DCB) may overcome some of the limitations of drug-eluting stents (DES). Therefore, we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions, and compared it with the conventional DES-only strategy. METHODS: We retrospectively enrolled patients with de novo ostial lesions in the LAD or LCx who underwent interventional treatment. They were categorized into two groups based on their treatment approach: the DCB group and the DES group. The treatment strategies in the DCB group involved the use of either DCB-only or hybrid strategies, whereas the DES group utilized crossover or precise stenting techniques. Two-year target lesion revascularization was the primary endpoint, while the rates of major adverse cardiovascular events, cardiac death, target vessel myocardial infarction, and vessel thrombosis were the secondary endpoints. Using propensity score matching, we assembled a cohort with comparable baseline characteristics. To ensure result analysis reliability, we conducted sensitivity analyses, including interaction, and stratified analyses. RESULTS: Among the 397 eligible patients, 6.25% of patients who were planned to undergo DCB underwent DES. A total of 108 patients in each group had comparable propensity scores and were included in the analysis. Two-year target lesion revascularization occurred in 5 patients (4.90%) and 16 patients (16.33%) in the DCB group and the DES group, respectively (odds ratio = 0.264, 95% CI: 0.093-0.752, P = 0.008). Compared with the DES group, the DCB group demonstrated a lower major adverse cardiovascular events rate (7.84% vs. 19.39%, P = 0.017). However, differences with regard to cardiac death, non-periprocedural target vessel myocardial infarction, and definite or probable vessel thrombosis between the groups were non-significant. CONCLUSIONS The utilization of the DCB approach signifies an innovative and discretionary strategy for managing isolated ostial lesions in the LAD or LCx. Nevertheless, a future randomized trial investigating the feasibility and safety of DCB compared to the DES-only strategy specifically for de novo ostial lesions in the LAD or LCx is highly warranted.

AIM: To investigate the changes in retinal nerve fiber layer(RNFL)and macular retinal thickness(MRT)in children with refractive abnormalities and amblyopia, and their predictive value of outcome.METHODS: A total of 168 children with myopic refractive abnormalities and monocular amblyopia admitted to our hospital from January 2020 to October 2022 were selected as the observation group, with 118 cases of mild to moderate amblyopia and 50 cases of severe amblyopia, and 168 children with normal vision were included as the control group in a 1:1 ratio during the same period. The changes of RNFL and MRT in two groups of children were statistically counted, and the correlation between the severity of refractive abnormalities and RNFL and MRT in children with amblyopia was analyzed. Additionally, the observation group was divided into effective subgroup and ineffective subgroup based on the therapeutic effect. The general information, as well as RNFL and MRT of the effective subgroup and the ineffective subgroups before and after treatment were compared. Logistic was used to analyze the factors influencing efficacy, and ROC curves was plotted to analyze the predictive value of RNFL and MRT alone or in combination for efficacy.RESULTS: RNFL and MRT of cases of severe amblyopia were higher than those of the mild to moderate amblyopia and the control groups(all P<0.05); the severity of amblyopia in children with refractive abnormalities is positively correlated with RNFL and MRT(rs=0.745 and0.724, both P<0.001); among patients of mild to moderate and severe, there were statistically significant differences between the effective and ineffective subgroups in terms of initial treatment age, fixation form, treatment compliance, as well as RNFL, MRT, and their differences before and 1mo postoperatively(all P<0.05). Logistic analysis showed that initial treatment age, fixation nature, treatment compliance, RNFL and MRT before and 1mo postoperatively were all factors influencing the therapeutic effect of amblyopia with refractive abnormalities in children(all P<0.05); after 1mo of treatment, the combined prediction of RNFL and MRT was significantly better than that of single prediction in children with mild to severe amblyopia.CONCLUSION:There are differences in RNFL and MRT in children with abnormal refractive amblyopia, and they are closely related to the different degrees and curative effects of children. The combination of RNFL and MRT after 1mo of treatment has certain value in predicting children with different degrees of abnormal refractive amblyopia.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

OBJECTIVE: To analysis the specific protein markers of essential thrombocythemia (ET) based on proteomics technology, to explore and verify the differential protein related to platelet activation. METHODS: Blood samples were obtained from ET patients and healthy people and a certain protein mass spectrometry was detected using label-free quantitative technology. The proteins relative abundance increased or down-regulated by 1.3 times in the disease group compared with the control group, and the protein abundance in the two groups t test P＜0.05 were defined as differential proteins. Bioinformatics analysis of the differential proteins was performed using GO and KEGG. The difference in the average protein abundance between the two groups was analyzed by t test and P＜0.05 was considered statistically significant. Differential proteins were selected for verification by parallel reaction monitoring (PRM) technology. RESULTS: A total of 140 differential proteins were found, of which 72 were up-regulated and 68 were down-regulated. KEGG enrichment showed that the differential protein expression was related to the platelet activation pathway. The differential proteins related to platelet activation were GPV, COL1A2, GP1bα, COL1A1 and GPVI. Among them, the expressions of GPV, GP1bα and GPVI were up-regulated, and the expressions of COL1A2 and COL1A1 were down-regulated. PRM verification of COL1A1, GP1bα, GPVI and GPV was consistent with LFP proteomics testing. CONCLUSION Differential proteins in ET patients are related to platelet activation pathway activation.Differential proteins such as GPV, GPVI, COL1A1 and GP1bα can be used as new targets related to ET platelet activation.

To investigate the relationship between serum uric acid to creatinine ratio (SUA/Cr) and metabolic syndrome (MS) and other indexes on physical examination population in Nantong area. Using the method of cross-sectional study, 8 148 physical examiners in the physical examination center of the Affiliated Hospital of Nantong University from January 2017 to April 2020 were used as the research objects, and the clinical data and serum biochemical indicators such as smoking and alcohol addiction, physical examination and so on were collected. According to the standard diagnosis of MS of Diabetes Society of Chinese Medical Association, the patients were grouped according to the quartile of SUA/Cr and the clinical data of each group were compared. Pearson correlation analysis and logistic regression analysis were used to explore the correlation between SUA/Cr and clinical indicators and the relationship between SUA/Cr and the risk of MS. The results showed that UA and SUA/Cr were the lowest in normal metabolism group, followed by abnormal metabolism group and the highest in MS group, The difference between the two groups was statistically significant (H=919.21 and 629.34, P<0.001). According to the SUA/Cr quartile, the population was divided into four groups. After adjusting for gender, age, smoking history and drinking history, SUA/Cr in group Q₁ was positively correlated with BMI and TG (r=0.061 and 0.080, P<0.05), but negatively correlated with HDL-C (r=-0.057, P<0.05). Multivariate logistic regression results showed that after adjusting for age, sex, smoking history and drinking history, the risk of MS for BMI, SBP, DBP, FBG, TG, HDL-C and SUA/Cr [OR (95%CI)] were: 1.44 (1.41-1.47), 1.07 (1.06-1.07), 1.10 (1.10-1.11), 1.83 (1.73-1.92), 1.89 (1.79-1.99), 0.08 (0.06-0.10) and 1.54 (1.47-1.62). Compared with SUA/Cr group Q₁, the risk of MS in group Q₂, Q₃ and Q₄ increased by 75%, 162% and 346%, respectively. In conclusion, there was an independent positive correlation between SUA/Cr and MS risk in Nantong area.

Objective:To study the quality evaluation method of Cyperi Rhizoma processed with four excipients. Method:Ultra-performance liquid chromatography （UPLC） fingerprints of raw products and processed products with four excipients of Cyperi Rhizoma were established， and the changes of chemical components in the fingerprints before and after processing were compared by chemometric analysis. The mobile phase was consisted of methanol （A）-water （B） for gradient elution （0-10 min， 5%-40%A； 10-30 min， 40%-70%A； 30-40 min， 70%A） at a flow rate of 0.3 mL·min^-1. The injection volume was 3 μL， the column temperature was 35 ℃， and the detection wavelength was 280 nm. The content changes of main index components in Cyperi Rhizoma before and after processing were compared by UPLC. The mobile phase was methanol-water （75∶25） and the detection wavelength was 242 nm. Result:Processing with four excipients had a significant impact on the overall characteristics of chemical components in the fingerprint of Cyperi Rhizoma. A total of 28 characteristic peaks were identified in fingerprints of the raw and processed products. Among them， peaks 1， 2 and 4 were specific peaks of the processed products， peak 5 was characteristic peak of the raw products. Peak 2 was identified as 5-hydroxymethylfurfural， peak 24 as cyperenone and peak 27 as α-cyperone. The 5-hydroxymethylfurfural produced by the processing with four excipients came from rice vinegar， rice wine and Maillard reaction of polysaccharides in Cyperi Rhizoma. The results of determination showed that there was no significant difference in the content of cyperenone after processing， but the content of α-cyperone decreased significantly. Conclusion:In the process of Cyperi Rhizoma processed with four excipients， there are new components produced by structural transformation， which are accompanied by changes in the content of index components. In this study， the quality of raw and processed products of Cyperi Rhizoma can be rapidly and effectively evaluated from qualitative and quantitative aspects.

OBJECTIVE: To compare the clinical effect differences between "'s five-needle method" and routine acupoint selection on allergic rhinitis and asthma syndrome. METHODS: A total of 210 patients with allergic rhinitis and asthma syndrome were randomly divided into an observation group (105 cases, 4 cases dropped off) and a control group (105 cases, 4 cases dropped off). The patients in the observation group were treated with "'s five-needling method", and the acupoints of Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12), Yintang (GV 29), Shangyingxiang (EX-HN 8) and Hegu (LI 4), etc. were selected; the patients in the control group was treated with routine acupuncture, and the acupoints of Feishu (BL 13), Zhongfu (LU 1), Taiyuan (LU 9), Dingchuan (EX-B 1), Danzhong (CV 17), Yintang (GV 29), Fengmen (BL 12) and Zusanli (ST 36), etc. were selected. The treatment in the two groups was given once a day, 6 times a week, for 4 weeks. The score of symptoms and signs was observed before and after treatment as well as 1 month, 2 months and 3 months after treatment. The forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF) and eosinophils in peripheral blood were measured before and after treatment in the two groups. After treatment, the clinical therapeutic effect was compared between the two groups. RESULTS: The total effective rate was 98.0% (99/101) in the observation group, which was superior to 94.1% (95/101) in the control group (<0.01). Compared before treatment, the total score of symptoms and signs in the two groups was significantly decreased at 1, 2, 3 and 4 weeks of treatment (<0.01); after treatment and at each time point of follow-up, the total score of symptoms and signs in the observation group was lower than that in the control group (<0.01). Compared with 4 weeks of treatment, the total score of symptoms and signs at each time point of follow-up was not statistically different in the observation group (>0.05), and the total score of symptoms and signs in the third month of follow-up in the control group was significantly increased (<0.05). After treatment, FEV1 and PEF in the two groups were increased (<0.01), eosinophil count in peripheral blood was decreased (<0.01), and the improvement in the observation group was greater than that in the control group (<0.01, <0.05). CONCLUSION "'s five-needle method" can improve the clinical symptoms and pulmonary function, reduce the count of eosinophils in peripheral blood in patients with allergic rhinitis and asthma syndrome, and the curative effect is better than routine acupuncture.
