Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Autologous hair transplantation provides an idea for the treatment of cicatricial alopecia, which makes the transplanted hair show a natural growth state. This paper introduces the cicatricial alopecia and autologous hair transplantation and reviews the application and limitations of autologous hair transplantation in treating cicatricial alopecia.

Objective To explore the therapeutic effect of different doses of botulinum toxin A injections on bromhidrosis.Methods A total of 200 cases were divided into mild-to-moderate group (N=100) and severe group (N=100) based on the grade of bromhidrosis,and each group was further divided into two groups:low dose group (50 cases) were treated by botulinum toxin A injections (100 U) and high dose group (50 cases) were treated with 200 U for bilateral axillary.The total effective rate and recurrence rate in both groups were compared.Results In the mild to moderate group,after treatment for 3 months,the total effective rate of both groups had no statistical difference (P＞ 0.05),and the same with recurrence rate in 6 months follow-up (P＞0.05).In the severe group,after treatment for 3 months,the total effective rate of the high dose group (82％) was significantly higher than that of the low dose group (64％),with statistical significance (x2 =4.110,P＜0.05).After 6 months follow-up,recurrence rate in the high dose group (22％) was significantly lower than that of the low dose group (46％),with statistical significance (x2 =6.417,P ＜ 0.05).Conclusions A suitable dose of botulinum toxin A can be selected based on the severity of bromhidrosis,which is a individualized therapy for cost savings and might have potential benefits for patients with osmidrosis.

Objective: To investigate the early diagnosis method of pulmonary embolism in patients with skin and soft tissue defects after trauma. Methods: From January 2011 to July 2014, 5 patients with skin and soft tissue defects and pulmonary embolism after trauma were admitted to Department of Plastic Surgery and Burns of the Affiliated Drum Tower Hospital of Nanjing University Medical School, including 4 males and 1 female, aged 26-68 years. The medical records of the 5 patients were retrospectively analyzed. Hierarchical screening of patients with suspected pulmonary embolism was performed after admission for 4-45 days. Computed tomography pulmonary angiography (CTPA) was performed immediately in 2 patients who had hemodynamic disorder and were able to tolerate CTPA, and pulmonary embolism was confirmed. Clinical risk assessment was conducted for the other 3 patients who had no obvious hemodynamic disorder and only had clinical manifestations of pulmonary embolism such as chest tightness and dyspnea. Among the 3 patients, two of them were assessed as high risk possibility by clinical risk assessment and diagnosed with pulmonary embolism by CTPA immediately. The other one patient′s clinical risk assessment was moderate risk possibility, but D-dimer was positive, and the patient was diagnosed with pulmonary embolism by CTPA immediately. Wound exudation of all patients was collected within 1 week after admission for microbial culture, and wound debridement and skin grafting were performed according to the wound condition. The color Doppler ultrasonography of blood vessel on lower extremity was performed to determine deep venous thrombosis of lower extremity after appearance of symptoms of pulmonary embolism. The patient was immediately given urokinase or recombinant tissue plasminogen activator by intravenous infusion for thrombolysis after definite diagnosis of pulmonary embolism. The activated partial thromboplastin time (APTT) was monitored after treatment, and standardized anticoagulation began when APTT was equal to or lower than 70 seconds. The treatment results of patients, D-dimer measurement value, bed time before definite diagnosis of pulmonary embolism, number of patients underwent wound debridement during hospitalization, definite diagnosis time of pulmonary embolism after wound debridement, and number of patients with deep venous thrombosis of lower extremity and wound infection were recorded. Results: Wounds with skin and soft tissue defects of all patients were completely healed, all skin grafts survived well, pulmonary embolism recovered well after timely treatment, and the trunk and branches of involved pulmonary artery recovered blood supply. The course of disease ranged from 1 month to 3 months. The measurement value of D-dimer was 2.4-31.7 mg/L, and the measurement values of D-dimer of 4 patients were equal to or higher than 5.0 mg/L. The bed time before definite diagnosis of pulmonary embolism was 4-46 days, with an average of 23.2 days. Four patients underwent wound debridement during hospitalization. The definite diagnosis time of pulmonary embolism after the wound debridement was 14-40 days, with an average of 20.5 days. Four patients were diagnosed with deep venous thrombosis of lower extremity. All patients had wound infection, and the bacteria causing wound infection included Pseudomonas aeruginosa of 2 cases, Staphylococcus aureus of 2 cases, and Enterococcus faecalis of 1 case. Conclusions In the diagnosis process of pulmonary embolism in patients with skin and soft tissue defects after trauma, D-dimer positive, long-term bed rest, experiencing operation during hospitalization, and with deep vein thrombosis and wound infection can be regarded as the key points for diagnosis. When a patient has clinical symptoms of pulmonary embolism and the above conditions, the clinician should promptly perform hierarchical screening, select the corresponding examination to confirm pulmonary embolism, and immediately perform thrombolysis for the patient with pulmonary embolism according to the patient′s tolerance, thereby improving patient survival rate.

Objective: To study the correlation between the level of serum Chitinase-3-like protein 1 (CHI3L1) and the significant liver fibrosis and liver cirrhosis in patients with chronic liver disease, and to evaluate its diagnostic value. Methods: 165 patients with chronic liver disease were selected, liver histopathological examination was performed to detect serum CHI3L1 concentration. Four indexes of hepatic fibrosis (type III procollagen, collagen IV, laminin, hyaluronic acid), aspartate aminotransferase/platelet ratio index (APRI) and FIB-4 (fibrosis- 4) scores were based on the pathological findings of liver biopsy and compared the advantages and disadvantages of serum CHI3L1 with other methods for the diagnosis of hepatic fibrosis and liver cirrhosis. A multivariate regression analysis model was created, and receiver operating characteristic curve was analyzed. Results: The level of serum CHI3L1 increased with increase of fibrosis stage and was highest in liver cirrhosis stage. In the period of S0 to 1, the levels of S2 to 3 and S4 were 62.82 (41.40 ~ 87.20), 70.94 (48.47 to 122.60) and 141.06 (78.18 ~ 197.40), and there were statistically significant differences between the groups (P < 0.001). The area under the curve for the diagnosis of significant liver fibrosis was 0.68 (0.60 to 0.77), and 0.74 (0.65 to 0.83) for cirrhosis in CHI3L1. Multivariate regression analysis showed that CHI3L1 was an independent predictor of significant fibrosis and cirrhosis. The combined diagnostic model based on CHI3L1, collagen IV and FIB-4 scores further improved the diagnostic value. The area under the curve for the diagnosis of significant fibrosis and cirrhosis was 0.79 (0.72 to 0.86) and 0.80 (0.73 to 0.87), respectively. Conclusion CHI3L1 has a good diagnostic value in patients with chronic liver disease with significant fibrosis and liver cirrhosis. The diagnostic model in combination with other markers like Collagen IV and FIB-4 scores could further improve the diagnostic value and is worthy of further study.

This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5-3.0 g/(kg·d)) from the beginning of the study, and the non-L-T4-treated subgroup received placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as the higher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulating hormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lower height velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treated subgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV compared with children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormone deficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.
