Objective:To examine the clinical value of combining indocyanine green (ICG) fluorescence navigation with blue dye in sen-tinel lymph node biopsy (SLNB) for patients with breast cancer. Methods:A total of 89 patients with early-stage breast cancer who met the inclusion criteria were admitted at Shantou Central Hospital, Guangdong from May 2013 to April 2014. In phase one, ICG and blue dye were applied in all 53 patients, and then SLNB and axillary lymph node dissection (ALND) were performed based on fluores-cence signal or visual sense of the lymph nodes. In phase two, 36 patients with early-stage breast cancer were included. ALND was omitted when sentinel lymph nodes were frozen showing negative result. Rates of detection, accuracy, and false-negative were calcu-lated. Results:A total of 89 patients were monitored, of which the total rate of SLNB detection was 96.6%(86/89). In the validation pe-riod, the rates of detection, accuracy, and false-negative were 94.3%(50/53) 98.0%(49/50), and 2.6%(1/38), respectively. In the alter-ative period, the rates of detection reached 100%. Of the 196 sentinel lymph nodes, 179 showed fluorescence signal, 142 exhibited blue dying, 54 only demonstrated fluorescence signals, and 45 demonstrated metastasis with five signaling fluorescence. About 24.7%of patients were diagnosed with SLN metastasis (22/89), where SLNB in two patients showed fluorescence signal but without blue dye. No ipsilateral lymph node relapsed were observed during a median follow up of 25 months. Conclusion:Combination of ICG fluores-cence navigation with blue dye in SLNB is safe for patients with breast cancer.

In order to determine the pathophysiologic significance of electrocardiographic ventricular hypertrophy in athletes (LVH ath), echocardiographic measurements of left ventricular mass (LVM) were performed on 50 LVH ath. and 50 non-LVH matched ath. They were members of National Teams of track and field, swimming, football and cycling, with an average age of 20.74?3.3 years. Anatomic validation of the method was used for calculation of LVM in this study. Comparisons of LVM were made between LVH ath. and non-LVH ath., and between non-LVH ath. and the untrained:LVM=1.04?[(LVID+PWT+IVST)~3-(LVID)~3]-14Results showed no significant difference of LVM between LVH ath. and non-LVH ath. while LVM of non-LVH ath. were considerably greater than that of the untrained (P

Objective: To improve the diagnosis and therapy of childhood pulmonary thromboembolism (PTE) by analyzing the clinical features of this rare condition. Methods: A total of 8 pediatric patients (4 males, 4 females) with PTE diagnosed in the Children′s Hospital of Zhejiang University School of Medicine from March, 2014 to March, 2019 were enrolled. The clinical manifestation, laboratory results, imaging findings, diagnosis and treatment were summarized. Results: Among these 8 cases, aged from 9 hours to 14 years and 10 months. Fever was found in 4 cases, cough aggravation in 4, short of breath in 3, chest pain in 2, abdominal and back pain in one, hemoptysis in 2, cyanosis in 1, and edema of lower extremities in 2. Physical examination found decreased breath sound in 2 cases, phlegm rale in 3, and pleural friction rub in one. Pleural effusion was found in 5 cases by ultrasound. Plasma D-dimer increased in 6 cases (0.66-9.96 mg/L) and hypersensitive C-reactive protein elevated in 5 cases (10.78-78.00 mg/L). Chest enhanced CT showed pulmonary artery or venous filling defects, including pulmonary artery embolism in 7 cases and pulmonary vein embolism in one. The primary disease of these patients included Mycoplasma Pneumoniae pneumonia in 4 cases, nephritis in 2 and postoperative congenital heart disease in 2. Apart from one case who withdrew the treatment and was discharged, the other 7 patients received anticoagulant treatment had good outcome. Conclusions For children with Mycoplasma pneumoniae pneumonia, immune disorders, long-term hormone therapy, cardiovascular invasive operation or other high-risk factors, PTE should be considered when fever, cough aggravation, short of breath, chest and back pain with pleural effusion are present. Chest enhanced CT scan should be performed as soon as possible, and anticoagulation should be started once the diagnosis is confirmed.

Objective: To analyze the influencing factors and clinical significance of severe hypocalcemia in patients with extremely severe burns in early stage. Methods: Clinical data of 142 patients with extremely severe burns admitted to our wards from January 2010 to July 2015, conforming to the study criteria, were retrospectively analyzed. (1) The incidence of hypocalcemia and severe hypocalcemia on admission were calculated. (2) Patients were divided into the male group (n=113) and the female group (n=29) according to gender. The levels of serum calcium of patients whose age more than 55 years old and less than or equal to 55 years old in the two groups were compared with t test. (3) Patients were divided into severe hypocalcemia group (n=52) and non-severe hypocalcemia group (n=90) according to the level of serum calcium on admission. The data including gender, age, flame burn, total burn area, inhalation injury, admission time, the pH value, and the albumin level of patients on admission between two groups were compared with chi-square test or t test. Indexes with P<0.1 between two groups were selected, and multivariate logistic regression analysis was conducted to screen the influencing factors of severe hypocalcemia in patients with extremely severe burns in early stage. (4) According to the prognosis, patients were divided into survival group (n=112) and non-survival group (n=30). The data including gender, age, flame burn, total burn area, inhalation injury, admission time, the level of serum calcium, the pH value, and the albumin level of patients on admission between two groups were compared with chi-square test or t test. Indexes with P<0.1 between two groups were selected, and multivariate Cox regression analysis was conducted to screen the influencing factors of prognosis of patients with extremely severe burns. Results: (1) The incidence of hypocalcemia on admission was 97.2% (138/142), and patients diagnosed as severe hypocalcemia accounted for 36.6% (52/142). (2) In the male group, the level of serum calcium of patients with age more than 55 years old was (1.84±0.19) mmol/L, which was close to (1.88±0.21) mmol/L of patients with age less than or equal to 55 years old within the same group and (1.96±0.13) mmol/L of patients with age more than 55 years old in the female group (t=0.833, 1.560, P>0.05). In the female group, the level of serum calcium of patients with age less than or equal to 55 years old was (1.78±0.19) mmol/L, which was significantly lower than that of patients with age less than or equal to 55 years old in the male group and that of patients with age more than 55 years old in the female group (t=-2.197, -2.472, P<0.05). (3) Compared with those of patients in severe hypocalcemia group, the total burn area and the proportion of inhalation injury of patients in non-severe hypocalcemia group were obviously smaller (t=2.379, χ² =13.410, P<0.05 or P<0.01), and the admission time was obviously earlier (t=2.675, P<0.01), while the albumin level was obviously higher (t=-6.163, P<0.01). There were no statistically significant differences between patients of the two groups in gender, flame burn, age, and the pH value on admission (χ²=1.869, 2.850, t=-0.578, 0.645, P>0.05). Multivariate logistic regression analysis showed that only the albumin level on admission was the independent influencing factor of severe hypocalcemia in patients with extremely severe burns (with odds ratio 1.179, 95% confidence interval 1.092-1.273, P<0.01). (4) Compared with those of patients in non-survival group, the total burn area and the proportion of inhalation injury in survival group were smaller (t=-5.515, χ²=27.573, P<0.05 or P<0.01), while the pH value and the albumin level on admission were higher (t=2.208, 3.321, P<0.05 or P<0.01). There were no statistically significant differences between patients of the two groups in gender, flame burn, age, admission time, and the level of serum calcium on admission (χ²=0.198, 2.545, t=-1.316, -1.397, 1.857, P>0.05). Multivariate Cox regression analysis showed that total burn area and inhalation injury were the independent risk factors to predict prognosis of patients with extremely severe burns (with relative risk 1.066 and 4.081, 95% confidence interval 1.023-1.110 and 1.144-14.559, P<0.05 or P<0.01), but the pH value and levels of albumin and serum calcium were not independent risk factors to predict prognosis of patients with extremely severe burns (with relative risk 0.003, 1.025, and 0.634, 95% confidence interval <0.001-1.183, 0.956-1.099, and 0.055-7.321, P>0.05). Conclusions The level of serum calcium of the majority of patients with extremely severe burns on admission is decreasing significantly, especially the female patients less than or equal to 55 years old. Compared with non-severe hypocalcemia patients, patients with severe hypocalcemia are with larger total burn area, higher proportion of inhalation injury, later admission time, and lower albumin level on admission. However, only the albumin level on admission is the independent influencing factor of severe hypocalcemia in patients with extremely severe burns. And the level of serum calcium on admission can not predict the prognosis of patients with extremely severe burns.

Objective: To retrospectively analyze the prognostic value of platelet count recovery in the early stage post burn for patients with extremely severe burn, so as to evaluate their severity. Methods: A study involving 244 adult patients with extremely severe burn admitted to our hospital from January 2006 to December 2015, conforming to the inclusion criteria, was conducted. Data of their demography, injury, transmission, disease change in hospital, and platelet count from post injury day (PID) 1 to 10 were collected. (1) Patients were divided into survival group (n=212) and non-survival group (n=32) according to whether death or not. The dynamic change characteristic of platelet count in patients of two groups from PID 1 to 10 was analyzed and compared. (2) Patients were divided into return to normal group (RN, n=163) and non-return to normal group (NRN, n=81) according to whether platelet count returned to normal within one week post burn. The proportion of patients who received mechanical ventilation and mortality in groups RN and NRN, and length of stay in ICU between patients with platelet count that returned to normal and that did not return to normal in the early stage post burn in survival group were compared. Data were processed with independent samples t test , analysis of variance of repeated measurement, chi-square test, and binomial distribution test. Correlation was analyzed between data of sex, age, weight, total burn area, full-thickness burn area, inhalation injury, length of hospital stay, receiving mechanical ventilation, platelet count recovery condition within one week post burn and death of patients using the univariate and multivariate Cox regression analysis. Receiver operating characteristic (ROC) curve of platelet count on PID 8 was drawn to evaluate predicting value for death of 244 patients. Results: (1) The platelet count kept declining from PID 1 to 4, declined to below the normal low limit on PID 2, and reached its lowest level on PID 4 both in survival group and non-survival group. The platelet count both in survival group and non-survival group rose gradually from PID 4 to 10, and returned to normal on PID 8 and 10, respectively. There was no significant difference in platelet count of patients in two groups on PID 1 (t=1.01, P>0.05), while platelet count of patients in non-survival group was obviously lower than that in survival group from PID 2 to 10 (with t values from 2.64 to 7.17, P values below 0.01). The daily increment of platelet count in survival group from PID 4 to 10 was (26±13)×10⁹/L, obviously higher than that in non-survival group [(19±11)×10⁹/L, t=2.76, P<0.01]. (2) The proportion of patients who received mechanical ventilation was obviously lower than that of patients who did not receive mechanical ventilation in group RN (P<0.01), while the proportion of patients who received mechanical ventilation was obviously higher than that of patients who did not receive mechanical ventilation in group NRN (P<0.05). The proportion of patients who received mechanical ventilation in group NRN was obviously higher than that in group RN (χ²=32.93, P<0.01). The mortality of patients in group NRN was obviously higher than that in group RN (χ²=20.99, P<0.01). The length of stay in ICU of patients whose platelet count did not return to normal in the early stage was significantly longer than that of patients whose platelet count returned to normal in the early stage in survival group (t=4.20, P<0.01). (3) Total burn area, receiving mechanical ventilation, and platelet count did not return to normal within one week post burn were independent risk factors for death of patients with extremely severe burn (with hazard ratio respectively 1.073, 16.552, and 2.249, 95% confidence interval respectively 1.033-1.115, 2.147-127.580, and 0.993-5.096, P<0.05 or P<0.01). (4) The area under the ROC curve of platelet count on PID 8 to predict death of 244 patients with extremely severe burn was 0.745 (with 95% confidence interval 0.645-0.845, P<0.01), and 150×10⁹/L was chosen as the optimal threshold value, with sensitivity of 71.4% and specificity of 71.0%. Conclusions Platelet count recovery in the early stage post burn of patients with extremely severe burn was significantly associated with their prognosis and could be used as an important indicator to evaluate the severity of illness.

Objective:To compare the curative effects of butterfly-shaped flap based on the dorsal branch of digital artery (hereinafter referred to as butterfly-shaped flap) and propeller flap based on the dorsal branch of digital artery (hereinafter referred to as propeller flap) in repairing the wound in volar aspect of finger.Methods:A retrospective cohort study was conducted. From August 2018 to April 2022, 16 patients with finger palmar wounds admitted to Ruijin Hospital of Shanghai Jiao Tong University School of Medicine and 7 patients with finger palmar wounds admitted to General Hospital of PLA Central Theater Command met the inclusion criteria, including 14 males and 9 females, aged 25 to 64 years. After debridement or resection of skin benign tumor, the wounds ranged from 0.5 cm×0.5 cm to 1.5 cm×1.5 cm. According to the different rotation axes of flap pedicle during wound repair, the patients were divided into butterfly-shaped flap group (8 cases) and propeller flap group (15 cases), and their wounds were repaired by butterfly-shaped flap (with area of 0.5 cm×0.5 cm-1.5 cm×1.3 cm) or propeller flap (with area of 0.7 cm×0.5 cm-1.5 cm×1.5 cm) , respectively. In propeller flap group, wounds in the donor sites were repaired by full-thickness skin grafts taken from the palms of wrists or the groin. The surgical time, postoperative complications, flap survival, and wound healing time of patients in the two groups were recorded. Data were statistically analyzed with independent sample t test, Mann Whitney U test, or Fisher's exact probability test. Results:The surgical time and postoperative wound healing time of patients in butterfly-shaped flap group ((43±9) min and (13.1±0.8) d, respectively) were both significantly shorter than those in propeller flap group ((87±16) min and (16.7±4.6) d, respectively, with t values of -7.03 and -2.86, respectively, P<0.05). The postoperative flap survival and complications of patients between the two groups were both similar ( P>0.05). Conclusions:For repairing the wound in volar aspect of finger, the butterfly-shaped flap has more advantages in comparison with the traditional propeller flap. The butterfly-shaped flap has a short surgical time and fast postoperative recovery, which is worthy of clinical promotion.

OBJECTIVETo investigate effects of systemic red light therapy on wound repair of burned patients and discuss its possible mechanisms of wound healing promotion.

METHODS138 burned patients were randomly divided into systemic red light treatment group (n = 69) and control group (n = 69). Patients in control group received routine therapy, while those in test group were given systemic red light therapy once a day, 30 minutes at a time until the wounds were recovered. The clinical findings and variables indicating wound repair were assessed on the 7th, 10th, 14th day, 21st day post-burn and the day when the wounds were healed.

RESULTSMean time of wound recovery were 19.86 +/- 2.43 days and 21.02 +/- 2.97 days respectively of those deep-thickness wounds in test group and control group, with statistically significance (P < 0.05). For the severity of the pain, VAS during time of dressing change on the 10th, 14th day post burn was lower in test group than that in control group which indicated less painful in test group (P < 0.05), suggesting pain relief effect of systemic red light therapy.

CONCLUSIONSystemic red light therapy was effective to promote wound healing of deep-thickness burn wounds and other similar acute wounds. Simultaneously, it is efficacious in pain relief and safe for those patients.

Objective To study the effect of multi-disciplinary team (MDT) management on the outcome in neonates with omphalocele.Method A retrospective non-randomized controlled clinical study was conducted.Neonates who were diagnosed as omphalocele and admitted to the surgical neonatal intensive care unit of the Guangzhou Women and Children Medical Center from December 2010 to December 2017 were collected.Because MDT was established in December 2014,infants were assigned into non-MDT group and MDT group according to their dates of admission.The characteristics and outcomes between non-MDT group and MDT group were compared using x2,t-test or rank-sum test.Multivariate analysis was performed by Logistic regression.Result A total of 91 neonates were included in the study,50 were in non-MDT group and 41 were in MDT group.The mortality in MDT group (2.4％,1/41) was lower than that in non-MDT group (18.0％,9/50),the difference was statistically significant (P ＜ 0.05).The median time of mechanical ventilation of giant omphalocele in non-MDT group (18.3 hours) was longer than that in MDT group (41.7 hours),the difference was also statistically significant (P ＜ 0.05).After adjusting for the associated confounding risk factors,the risk of death in non-MDT group was 54 times higher than that in MDTgroup (OR=54.19,95％CI2.64 ～1 113.49,P＜0.05).Conclusion There was significant association between the MDT management and the decreased risk of death of omphalocele.

Objective:To investigate the clinical effect of self-designed modified rhomboid flap in repairing rhomboid, round, and teardrop-shaped wounds on the face.Methods:A retrospective observational study was conducted. From August 2018 to April 2020, 30 patients with facial lesions admitted into Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the People's Hospital of Jianchuan County in Yunnan province met the inclusion criteria, including 16 males and 14 females, aged 23 to 88 years. The wound area ranged from 1.0 cm×1.0 cm to 7.0 cm×5.0 cm, with 10 cases of rhomboid wounds, 12 cases of round wounds, and 8 cases of teardrop-shaped wounds. The self-designed modified rhomboid flaps were applied to repair the wounds and after that, the patients were followed up for 1 to 18 months to record the survival of flaps, wound tension, scar formation and complications after surgery.Results:No necrosis or blackening was observed at the tip of the flaps after surgery. All the flaps survived and the wounds healed well with little tension, minimal scars, and no complications.Conclusions:The self-designed modified rhomboid flap is especially suitable for facial wounds with multiple important organs, multiple anatomical subunits, and areas with large changes in soft tissue tension, which can reduce not only the rotation of the flap, but also unnecessary excision of normal skin and soft tissue.
