ABSTRACT

Objective:To investigate the clinical efficacy of triamcinolone acetonide peribulbar injection combined with vitrectomy for rhegmatogenous retinal detachment associated with choroidal detachment (RRD-CD).Methods:This study was a retrospective case series study. Nineteen cases (19 eyes) with RRD-CD who had undergone pars plana vitrectomy at the Dalian No.3 People′s Hospital were analyzed. All the cases received 20 mg triamcinolone acetonide peribulbar injection within 3 to 7 days before surgery. The severity of patient′s uveitis was assessed before and after peribulbar injection of triamcinolone acetonide. Best corrected visual acuity (BCVA) and intra ocular pressure (IOP) before and after surgery, the area of retinal detachment, the rate of retinal reattachment, the rate of recurrent retinal detachment and surgical complications were analyzed. Patients′ blood pressure and blood glucose levels were also monitored.Results:19 patients were followed up for (13.1±1.5)months. The severity of uveitis reduced to different extents compared with preoperative condition. The IOP was (8.73±3.38)mmHg before injection and (10.95±2.46)mmHg after injection, and the difference was statistically significant ( t=-7.571, P=0.027). The choroid detachment range was 4-12(9.37±2.69)sites before injection, and 0-11(4.63±4.10)sites after injection, and the difference was statistically significant ( Z=-3.834, P=0.001). Compared with the preoperative results, the BCVA increased in 12 patients, unchanged in 5 cases and decreased in 2 cases. In the final follow-up of 18 patients with retinal reattachment, 17 eyes underwent a single operation, 2 eyes had recurrent retinal detachment, and 1 eye had retinal reattachment after a second operation. There were no significant difference in blood glucose and blood pressure before and after injection (all P>0.05). There were no other complications besides temporarily elevated IOP and cataract. Conclusions:Vitrectomy combined with triamcinolone acetonide peribulbar injection is effective and safe for patients with RRD-CD.

ABSTRACT

BACKGROUND@#There are limited data on the resource utilization of total knee arthroplasty (TKA) in China. This study aimed to examine the length of stay (LOS) and inpatient charges of TKA in China, and to investigate their determinants.@*METHODS@#We included patients undergoing primary TKA in the Hospital Quality Monitoring System in China between 2013 and 2019. LOS and inpatient charges were obtained, and their associated factors were further assessed using multivariable linear regression.@*RESULTS@#A total of 184,363 TKAs were included. The LOS decreased from 10.8 days in 2013 to 9.3 days in 2019. The admission-to-surgery interval decreased from 4.6 to 4.2 days. The mean inpatient charges were 61,208.3 Chinese Yuan. Inpatient charges reached a peak in 2016, after which a gradual decrease was observed. Implant and material charges accounted for a dominating percentage, but they exhibited a downward trend, whereas labor-related charges gradually increased. Single marital status, non-osteoarthritis indication, and comorbidity were associated with longer LOS and higher inpatient charges. Female sex and younger age were associated with higher inpatient charges. There were apparent varieties of LOS and inpatient charges among provincial or non-provincial hospitals, hospitals with various TKA volume, or in different geographic regions.@*CONCLUSIONS@#The LOS following TKA in China appeared to be long, but it was shortened during the time period of 2013 to 2019. The inpatient charges dominated by implant and material charges exhibited a downward trend. However, there were apparent sociodemographic and hospital-related discrepancies of resource utilization. The observed statistics can lead to more efficient resource utilization of TKA in China.

ABSTRACT

In order to standardize the quality control of traditional Chinese medicine(TCM) dispensing granules, the Chinese Pharmacopoeia Commission has promulgated and implemented 200 national drug standards for TCM dispensing granules, but there are still varieties of TCM dispensing granules without unified standards. Many provinces have actively invested in the formulation of provincial standards for TCM dispensing granules to make up for the gaps in standards for varieties of traditional Chinese medicine dispensing granules other than the national standards. By the end of July 2022, 29 provincial-level administrative regions have successively promulgated and implemented a total of 5 602 provincial standards for TCM dispensing granules, involving more than 400 varieties. In order to better understand the formulation and characteristics of provincial standards, this study took 105 provincial standards that have been promulgated and implemented in Henan province as an example, and comprehensively analyzed the formulation and characteristics through quality control indicators such as dry extract rate of raw materials, contents of index components and their transfer rates, specifications and so on. The formulation and characteristics of the same TCM dispensing granules in the provincial standards of different provinces were further analyzed, in order to provide reference for the formulation of provincial standards of TCM dispensing granules and the implementation of national standards.

ABSTRACT

ObjectiveTo investigate the effect of transcranial direct current stimulation (tDCS) combined with constraint-induced weight training (CIWT) on Pusher syndrome after stroke. MethodsA total of 60 stroke inpatients with Pusher syndrome in the First Affiliated Hospital of Soochow University from January to December, 2021 were randomly divided into tDCS group, CIWT group and combination group, with 20 cases in each group. The three groups accepted routine rehabilitation training, the tDCS group received anode tDCS, the CIWT group received CIWT of the affected lower limb, and the combination group received CIWT of the affected lower limb and tDCS, for eight weeks. They were assessed with Berg Balance Scale (BBS), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Burke Lateropulsion Scale (BLS) and Holden Walking Functional Ambulation Category (FAC) before and after treatment. ResultsAfter treatment, the scores of BBS, FMA-LE, BLS and FAC improved (|t| > 1.452, P < 0.05) in all the groups, and improved the most in the combination group (|F| > 1.827, P < 0.05). ConclusiontDCS combined with CIWT of the affected lower extremity can effectively improve the function of stroke patients with Pusher syndrome.

ABSTRACT

ObjectiveTo investigate the effect and mechanism of pachymic acid (PA) in Poria on the invasion and metastasis of renal carcinoma cells. MethodThe effect of PA (0, 20, 40, 80, 160 μmol·L-1) on cell viability was detected by cell counting kit-8(CCK-8), and the dose of PA was selected for subsequent experiments. The effect of PA (0, 20, 40, 80 μmol·L-1) on cell proliferation was evaluated by colony formation assay. The effect of PA (0, 20, 40, 80 μmol·L-1) on cell adhesion ability was observed by cell adhesion assay. The effect of PA (0, 20, 40, and 80 μmol·L-1) on cell invasion and metastasis was investigated by Wound healing assay and Transwell invasion assay. The inhibitory effect of PA (0, 20, 40, 80 μmol·L-1) on cell motility was further observed and verified by high-content imaging technology. The effects of PA (0, 20, 40, 80 μmol·L-1) on the expression of matrix metalloproteinase (MMP)/tissue inhibitor of metalloproteinasas (TIMP) related to invasion and metastasis and Smads were detected by Western blot. ResultCCK-8 results showed that compared with the blank group, the PA groups showed decreased cell viability(P<0.01), with the half-maximal inhibitory concentration (IC50) of ACHN cells of 70.42 μmol·L-1 at 24 h. Colony formation assay showed that the number of cell clonal groups in the PA groups was reduced compared with that in the blank group(P<0.01). Cell adhesion assay showed that compared with the blank group, the PA groups displayed reduced cell adhesion(P<0.01). Wound healing assay showed that the wound healing rate of cells in the PA groups was lower than that in the blank group (P<0.05,P<0.01). Transwell invasion assay showed that compared with the blank group, the number of transmembrane cells in PA groups was reduced(P<0.01). High-content imaging showed that the cumulative migration distance of cells in the PA groups was shorter than that in the blank group(P<0.01). The results of Western blot showed that the protein expression of MMP-2 and MMP-9 in the PA groups decreased (P<0.01), and TIMP-1 protein expression increased (P<0.01) compared with those in the blank group. In addition, compared with the blank group, the PA groups showed decreased protein expression of Smad2 and Smad3 (P<0.01). ConclusionPA can inhibit the invasion and metastasis of renal carcinoma cells presumably through regulating the homeostasis of MMP/TIMP by Smad2/3.

ABSTRACT

Objective:To observe and summarise the clinical effect of free groin flap in repairing of soft tissue defects in extremities, and to explore the selection of main vessel in a flap.Methods:From January 2018 to January 2021, 146 patients with soft tissue defects in extremities were treated with free groin flaps in the Department of Hand and Microsurgery, Guangxi Guilin Xing'an Jieshou Orthopaedic Hospital. There were 126 patients with traumatic wound and 20 with chronic ulcer. In addition, 86 of the patients with bone fracture and exposure of internal fixator, 18 with tendon, nerve or artery injuries or defects. There were 6 patients with severe infection and other 3 with deep dead space. The sizes of wound ranged from 2.0 cm×3.0 cm to 25.0 cm×6.0 cm. The flap was the same size as the wound and not enlarged. Firstly, the superficial branch of superficial iliac circumflex artery was explored as the axial artery for all the flaps, then the blood supply vessels of the flap were selected according to the availability of the axial artery. The size, course, adjacent and possible length to be freed of the axial artery and the accompanying veins of a flap were recorded. The donor sites were directly sutured and closed. All patients were included in the postoperative follow-up at outpatient clinic.Results:Free groin flap were used to repair the wounds in all patients. However, the main blood supply vessel of the flap was not constant, and it was often required to adjust the way of flap harvesting. Superficial circumflex iliac artery was taken as the axial vessels in 141 patients (96.6%), among them, 133 cases(94.3%) had the superficial branch as the axis and 5 cases (3.6%) had deep branch as the axis. Three patients (2.1%) had the bone and soft tissue defects reconstructed with vascularised iliac mosaic osteocutaneous flap with superficial circumflex iliac artery as axial vessel and 5 cases(3.4%) had the superficial epigastric artery as axial vessel. The axial arteries were measured as follow: the superficial branch of the superficial circumflex iliac artery was 0.5-0.9 mm in diameter and 7.0-9.0 cm in length, the outer diameter of the deep branch was 1.2-1.4 mm and 9.0-11.0 cm in length, and the outer diameter of superficial epigastric artery was 1.0-1.6 mm and 8.0-11.3 cm in length. All the flaps survived smoothly after surgery and the follow-up period ranged 6-40 (mean 26) months. The texture of the flaps was soft with good function.Conclusion:Free groin flap can be used to repair soft tissue defects in extremities. The main axial vessel is the superficial branch of the superficial circumflex iliac artery, followed by the deep branch or the trunk. The superficial abdominal artery can also be used as an axial vessel. Under the circumstances, the flap design needs to be adjusted without changing the supply area

ABSTRACT

Objective:The purpose of this study was to investigate the evaluating value of modified critical care ultrasonic examination(M-CCUE) scheme for the etiological diagnosis of shock in ICU patients.Methods:The prospective study collected relevant clinical data of various shock patients admitted to the Department of Intensive Care Medicine, Henan Provincial People's Hospital from May 2020 to July 2021, including hemodynamic、blood indicators、organ/tissue perfusion and prognostic evaluation indicators.All selected patients completed the initial M-CCUE assessment within 30 minutes, were scored according to the M-CCUE score system and related data results were analyzed.Results:Ninety-three patients were included in this study,Two of them were not completed the M-CCUE assessment due to emergency treatment immediately after entering our department, and five were excluded due to inconsistent ultrasound judgments by the two physicians. In the end, a total of 86 patients were enrolled in the group. In patients applied with M-CCUE scheme,time to preliminary diagnosis and final diagnosis were (13.02±3.15)min and (67.70±20.20)min respectively, the accuracy of diagnosis was 83.7%. Among them, distributed shock accounted for 60.4%, hypovolemic shock accounted for 25.6%, cardiogenic shock and obstructive shock accounted for 3.5%, and mixed shock accounted for 7%; MCS is (13.27±4.91), M-CCUE scheme had the high sensitivity and specificity for the diagnosis of distributed shock (sensitivity 91.2%, specificity 93.9%), hypovolemic shock (sensitivity 96.0%, specificity 96.7%), cardiogenic shock (sensitivity 85.7%, specificity 98.7%) and obstructive shock (sensitivity 60.0%, specificity 100%); MCS has a good positive correlation with APACHEⅡ score ( r=0.861, P<0.001), and has no correlation with ICU cost ( r=0.012, P=0.915). There is no significant difference in MCS between the 28d death group and the recovery group ( P=0.391). Conclusions:For shock patients admitted to ICU with unknown etiology, the initial diagnosis of the cause of the M-CCUE program takes less time, has a higher correct diagnosis rate, sensitivity and specificity, and its quantitative evaluation results can predict the patient's criticality.

ABSTRACT

Systemic sclerosis is a rare and complex autoimmune disease, and malakoplakia is a rare chronic granulomatous inflammatory disease. Systemic sclerosis combined with malakoplakia is extremely rare. Diagnosis is difficult before surgery. It is easy to misdiagnose bladder malakoplakia as bladder tumor. This paper reports a middle-aged female patient with systemic sclerosis complicated with bladder malakoplakia. The main clinical manifestations were hematuria and bladder irritation, accompanied by severe diarrhea. Transurethral resection of bladder tumor was performed. Postoperative pathology proved that it was bladder malakoplakia. After the surgery, she continued to take low-dose prednisolone and methotrexate in the treatment of systemic sclerosis. The patient was followed up for 6 months.Transurethral cystoscopy was performed twice, and there was no recurrence.

ABSTRACT

Objective:To systematically analyze the influence of early removal of urinary catheters on urinary complications in middle-aged and elderly patients after transurethral resection of the prostate.Methods:Randomized controlled trials or clinical controlled trials on early removal of urinary catheters in patients after transurethral resection of the prostate were retrieved from PubMed, Embase, the Cochrane Library, the Web of Science, CNKI, Wanfang Data, VIP database and CBM.RevMan 5.3 was used to analyzed the data.Results:Nine randomized controlled trials and one controlled clinical trial involving a total of 1529 patients were included.The results of meta-analysis showed that there was a significant difference between catheter removal within three days after surgery and removal 4-7days after surgery in the incidence of urinary tract infections[ OR=0.34, 95% CI(0.20-0.58), P<0.01], but there was no significant difference in secondary hemorrhage[ OR=0.86, 95% CI(0.44-1.66), P>0.05].There was no significant difference in the incidence of re-catheterization or secondary hemorrhage between ≤24 hours and 2-3 days after surgery[ OR=1.32, 95% CI(0.57-3.06), P>0.05; OR=3.18, 95% CI(0.32-31.56), P>0.05]. Conclusions:Early postoperative catheter removal(within 3 days)has a clear advantage in reducing the incidence of urinary tract infections, and urinary catheter removal within 24 hours does not increase the incidence of re-catheterization or secondary hemorrhage compared with removal after 24 hours.

ABSTRACT

Objective:To estimate in-hospital mortality after knee replacement (KR) and to assess its trend and risk factors in China.Methods:We included patients undergoing KR in the Hospital Quality Monitoring System in China (2013-2019) to estimate in-hospital mortality after KR and assessed relation of patient's and hospital's characteristics (year of surgery, age, gender, marital status, primary indication, Charlson comorbidity index, geographic location, hospital type, hospital volume of KR, and surgery type) to in-hospital mortality using multivariable Poisson regression.Results:The annual amount of KR has increased from 20 307 in 2013 to 35 757 in 2019, and has maintained an upward trend for 7 years. The mean age of patients having KR increased from 64.9 years in 2013 to 66.6 years in 2019. Of the total 218 923 KRs, 63 deaths (0.29‰) occurred within 30 days before discharging. Older age was associated with higher in-hospital mortality ( P for trend <0.001). Male gender had higher incidence of in-hospital mortality compared with female [relative risk (RR), 2.5; 95% CI: 1.5, 4.1]. Single marital status was associated with higher, albeit non-statistically significant, in-hospital mortality than married patients (RR, 2.1; 95% CI: 0.9, 4.6). Higher Charlson comorbidity index was associated with increased risk of in-hospital mortality ( P for trend <0.001). Risk of in-hospital mortality decreased with more hospital-year knee replacement surgeries ( P for trend <0.001). In-hospital mortality varied by geographic regions, with the lowest mortality in East region (0.16‰), followed by South-West (0.31‰), South-Central (0.31‰), North region (0.33‰), North-West (0.54‰) and North-East (0.59‰). Conclusion:In-hospital mortality after KR in China was relatively low. Older age, male gender, higher Charlson comorbidity index and lower hospital-year knee replacement surgeries were risk factors for in-hospital mortality. The mortality varied greatly according to the geographic location of hospital.

ABSTRACT

Objective:To analyze the risk factors of pelvic organ prolapse (POP) and to establish the prediction model.Methods:A study was conducted on the prevalence of POP among 2 247 parturient women at 6 weeks postpartum in Peking University People′s Hospital from December 2018 to October 2019, and relevant influencing factors were analyzed to construct a prediction model of early postpartum POP using logsitic regression, which was validated internally. Data from November 2019 to December 2019 (403 parturient women) were collected for external validation of the prediction model. In addition, the obstetrical factors affecting the occurrence of early postpartum POP in 885 primiparas with vaginal delivery (from January 2019 to November 2019) were further discussed.Results:A total of 2 247 cases were included in the modeling group, and 403 cases were included in the external validation data set. POP accounted for 24.3% (545/2 247). Age, parity, body mass index before pregnancy, vaginal delivery and newborn birth weight were negative factors for early postpartum POP (all P<0.05). The nomogram was established based on the above factors, and internal and external verification indicated that the model had a good discrimination (C-index were 0.759 and 0.760, respectively). In addition, this study found that age and newborn birth weight were the main causes of early postpartum POP in primiparas with vaginal delivery ( P=0.044, P=0.004). Conclusions:The incidence of early postpartum POP is high. The prediction model of POP constructed in this study could be used to guide clinical practice to a certain extent and give corresponding treatment suggestions to pregnant women scientifically, so as to provide theoretical support for primary prevention.

ABSTRACT

ObjectiveTo study the inhibitory effect of Celastrus orbiculatus extract (COE) on gastric cancer cells, to clarify the specific mechanism of COE promoting the apoptosis of gastric cancer cells by affecting the mitochondrial structure and function, and to provide an experimental basis for the further development and clinical application of C. orbiculatus. MethodBrdu staining combined with flow cytometry and Annexin V-fluorescein isothiocyanate (AnnexinV-FITC) staining combined with flow cytometry were employed to detect the effects of COE (20, 40, 80 mg·L-1) on the proliferation and apoptosis of gastric cancer cells, respectively. The changes in mitochondrial membrane potential were detected with JC-1 mitochondrial membrane potential assay kit. The expression of apoptosis-associated proteins including B-cell lymphoma-2 (Bcl-2), B-cell lymphoma-xL (Bcl-xL), Bcl-2-associated X (Bax), and cysteine aspartutespecific protease-3 (Caspase-3) in gastric cancer cells was determined by Western blot. Transmission electron microscopy was employed to detect changes in the mitochondrial microstructure of gastric cancer cells exposed to COE. Western blot was employed to measure the expression of mitochondrial marker proteins [superoxide dismutase 1 (SOD1), voltage-dependent anion channel (VDAC), prohibitin 1 (PHB1), and heat shock protein 60 (HSP60)] in gastric cancer cells. ResultCompared with the control group, COE (40, 80 mg·L-1) inhibited the proliferation and promoted the apoptosis of gastric cancer cells (P<0.05). Furthermore, COE reduced the mitochondrial membrane potential of gastric cancer cells. Compared with the control group, COE (20, 40, 80 mg·L-1) up-regulated the expression of Bax and Caspase-3 which promoted apoptosis of gastric cells (P<0.05, P<0.01), and COE at 40 and 80 mg·L-1 down-regulated the expression of Bcl-2 and Bcl-xL which inhibited the apoptosis of gastric cancer cells (P<0.01). The results of transmission electron microscopy showed that COE changed the microstructure of gastric cancer cells, which led to the appearance of vacuoles in the cell membrane and mitochondria and damaged the mitochondrial structure. Compared with the control group, COE (20, 40, 80 mg·L-1) changed the expression of mitochondrial marker proteins. Specifically, it up-regulated the expression of SOD1 involved in stress response (P<0.05, P<0.01) and down-regulated that of VDAC, PHB1, and HSP60 associated with mitochondrial stability and permeability (P<0.01). ConclusionCOE can significantly inhibit the proliferation and promote the apoptosis of gastric cancer cells. It may activate the mitochondrial apoptosis pathway by destroying the mitochondrial structure and function of gastric cancer cells.

ABSTRACT

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

ABSTRACT

Objective:To investigate the relationship of mitochondrial DNA (mtDNA) copy number with clinicopathologic characteristics and its influence on the prognosis of hepatocellular carcinoma (HCC) patients.Methods:The retrospective case-control study was conducted. The clinicopathological data of 71 HCC patients undergoing surgical treatment in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University from March to June 2011 were collected. There were 61 males and 10 females, aged from 26 to 80 years, with a median age of 55 years. The mtDNA copy number of tumor tissues and adjacent normal tissues were measured for all patients. Observation indicators: (1) the mtDNA copy number of tumor tissues and adjacent normal tissues and relationship between the mtDNA copy number and clinicopathological characteristics of HCC patients; (2) follow-up; (3) related factors for the prognosis of HCC patients. Follow-up using outpatient examination or telephone interview was conducted to detect postoperative survival of patients up to September 2019. Measurement data with normal distribution were described as Mean± SD, and comparison between groups was analyzed using independent samples t test or the matched samples t test. Measurement data with skewed distribution were described as M(range). Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Univariate and multivariate analyses were conducted using the COX regressional model. Variables with P<0.10 in the univariate analysis were included for the multivariate analysis. Survival rates were calculated using the Kaplan-Meier method, and Log-rank test was used for survival analysis. Results:(1) The mtDNA copy number of tumor tissues and adjacent normal tissues and relationship between the mtDNA copy number and clinicopathological characteristics of HCC patients: of 71 HCC patients, the mtDNA copy number was 0.85±0.08 in tumor tissues, versus 1.16±0.08 in adjacent normal tissues, showing a significant difference between them ( t=2.96, P<0.05). Of 71 HCC patients, 48 cases were mtDNA-low and 23 cases were mtDNA-high. Cases with tumor capsule as integrity or not-integrity, cases with or without microvascular (MVI) in mtDNA-low and mtDNA-high patients were 20, 28, 21, 27 and 16, 7, 4, 19, respectively, showing significant differences ( χ2=4.84, 4.74, P<0.05). (2) Follow-up: 71 patients were followed up for 2.1 to 85.3 months, with a median follow-up time of 47.8 months. The 1-, 3-, 5-year overall survival rates of 71 HCC patients were 87.3%, 64.7, 37.4%, respectively. Moreover, the 1-, 3-, 5-year overall survival rates were 81.2%, 50.0%, 29.2% of the mtDNA-low patients, versus 95.7%, 86.5%, 54.7% of the mtDNA-high patients, showing a significant difference between the two groups ( χ2=5.86, P<0.05). (3) Related factors for the prognosis of HCC patients. Results of univariate analysis showed that the number of tumor, portal vein tumor thrombus, MVI, Barcelona Clinic Liver Cancer stage, mtDNA copy number were related factors for the prognosis of HCC patients ( hazard ratios=2.211, 2.911, 3.899, 3.587, 0.440, 95% confidence intervals as 1.024?4.777, 1.485?5.704, 2.115?7.186, 1.615?7.966, 0.223?0.871, P<0.05). Results of multivariate analysis showed that MVI and mtDNA copy number were independent influencing factors for the prognosis of HCC patients ( hazard ratios=2.754, 0.437, 95% confidence intervals as 1.374?5.521, 0.205?0.932, P<0.05). Conclusions:The mtDNA copy number of HCC patients is related with tumor capsule and MVI. The mtDNA copy number and MVI are independent influencing factors for the prognosis of HCC patients.

ABSTRACT

Objective:To explore and analyze the influence of thoracic types and symmetry methods on the treatment effect before operation for the breast cancer patients undergoing immediate breast reconstruction.Methods:From January to October 2018, 30 female patients with unilateral breast cancer, aged 33-48 (39.6±4.6) years, were treated in the Breast Center of Qingdao University Affiliated Hospital. Thoracic CT was used to analyze thoracic types and symmetry. The measurement indexes included the maximum transverse diameter of thorax, the maximum longitudinal diameter of left and right sides, the ratio of the maximum transverse longitudinal diameter of left and right sides, the anterior chest angle of left and right sides, the posterior chest angle and the external chest angle, and the type and symmetry of thorax were analyzed, and the choice of prosthesis was adjusted according to the measurement results.Results:All the 30 patients recovered smoothly, and no complications such as infection and prosthesis removal occurred. Anatomical prostheses were selected in 22 patients, including 12 cases with medium high protrusion prosthesis, 10 cases with low protrusion prosthesis and 8 cases with round low protrusion prosthesis. The average follow-up time was 15 months after operation. The postoperative follow-up photos were evaluated aesthetically by using the BRAST-Q questionnaire and 3 non-operative doctors, among which 22 cases were excellent, 4 cases were good, 3 cases passed and 1 case was poor. Excellent and good rate was 86.7%. Among them, 3 cases were satisfactory, 1 case was scar hyperplasia of local incision, 2 cases were mild capsular contracture, and 1 case was subject to prosthesis displacement.Conclusions:The measurement and analysis of thoracic type and symmetry before operation can help to adjust the choice of prosthesis, check the obvious thoracic deformity and avoid affecting the surgical results.

ABSTRACT

Objective:To explore the surgical method and clinical effect of forearm arterialized venous flap in repair of soft tissue defects of fingers.Methods:A total of 13 cases of finger soft tissue defects with exposure of deep tissue were repaired with forearm arterialized venous flap from January, 2013 to October, 2019. The flap was designed in the forearm, and 2 parallel superficial veins were selected, the diameter of vein was similar to that at recipient site. The long axis of the flap was the same as that of the vein, and the width of the flap was divided into 3 equal parts by the 2 superficial veins. The free flap was cut longitudinally in the middle between 2 vessels under microscope, and a width of about 2 mm of the subcutaneous tissue was removed to the subdermal vascular network. The communicating branch between 2 vessels was ligated, and the subcutaneous tissue between 2 vessels was cut completely. The flap was not inverted, and the cut area was 3.5 cm× 2.5 cm-7.0 cm×4.0 cm. The proximal ends of the 2 vessels in the flap were anastomosed with the arteries and veins of the recipient area.Results:Thirteen flaps survived, and 9 patient entered follow-up for an average of 11(3-23) months. The flaps were soft and had no effect on the joint movement, slightly bloated. The TPD of flaps was 9 - 18 mm, with an average of 13 mm.Conclusion:Forearm arterialized venous flap has the advantages of high survival rate, satisfactory function, finger pulp-type change, superficial location, easy harvest and no sacrifice of main artery. It is an ideal method for repairing finger soft tissue defects.

ABSTRACT

Objective:To assess the value of point of care ultrasound on cardiac output (CO) and volume responsiveness in patients with septic shock.Methods:A prospective investigation study was conducted. Twenty-four mechanical ventilation patients with septic shock who needed pulse-indicated continuous cardiac output (PiCCO) monitoring in the department of critical care medicine of Zhengzhou University People's Hospital, Henan Provincial People's Hospital from November 25, 2020 to April 30, 2021 were selected as the subjects, the patient's basic information and laboratory test results were recorded. PiCCO was used as standard to monitor CO and stroke volume variability (SVV) at 0, 2, 6, 12, 24 and 48 hours. At the same time, point of care transthoracic echocardiography (TTE) was used to measure velocity time integral (VTI) and inferior vena cava diameter (dIVC), the CO, VTI variation rate (△VTI) and dIVC variation rate (△dIVC) were calculated. Then, using the value monitored by PiCCO as the standard, the consistency and correlation analysis were carried out between point of care ultrasound with PiCCO.Results:Twenty-two out of 24 patients obtained satisfactory ultrasound Doppler images, the heart rate (HR), mean arterial pressure (MAP) and body temperature of the enrolled patients were consistent with the pathophysiological characteristics of septic shock. With the extension of treatment time, HR and CO both gradually decreased, and MAP gradually increased, reaching a peak or trough at 48 hours after admission. The difference were statistically significant compared with the time of admission [HR (bpm): 90.36±15.35 vs. 116.82±19.82, MAP (mmHg, 1 mmHg = 0.133 kPa): 87.82±11.06 vs. 58.82±9.85, CO (L/min): 4.80±0.56 vs. 6.78±1.31, all P < 0.05]. The CO obtained by PiCCO and point of care ultrasound had good agreement [5.36 (4.78, 6.33) L/min and 5.21 (4.88, 6.35) L/min, respectively], the average difference value at each time point was (-0.02±0.69) L/min, the 95% agreement limit range was -1.35-1.34, and there was a high degree of correlation ( rs = 0.800, P < 0.001); The SVV by PiCCO and the △dIVC by point of care ultrasound were in good agreement [18.00% (14.00%, 24.00%) and 21.00% (14.00%, 25.75%), respectively], the average difference value at the time point was (-3.16±6.89)%, the 95% agreement limit range was -16.89-10.54, and there was a moderate correlation ( rs = 0.702, P < 0.001); The SVV by PiCCO and the △VTI by point of care ultrasound were in good agreement [18.00% (14.00%, 24.00%) and 16.00% (11.25%, 20.75%), respectively], the average difference value at each time point was (13.03±14.75)%, and the 95% agreement limit range was 1.72-27.78, and there was a high correlation ( rs = 0.918, P < 0.001). Conclusion:Point of care ultrasound can accurately assess CO and volume responsiveness of patients with septic shock, and the △VTI is better than the △dIVC in assessing volume responsiveness.
