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.

OBJECTIVE: To compare the effect on facial acupoint temperature between acupuncture at Houxi (SI 3) and Dazhui (GV 14) so as to verify "Houxi (SI 3) communicating the governor vessel" based on the infrared thermal imaging technology. METHODS: Thirty-five healthy subjects (5 cases dropped off) were collected and before-after study in the same subject was adopted. The subjects were successively assigned into a sham-acupuncture group, a Houxi group, a Wangu group and a Dazhui group. Sham-acupuncture at Houxi (SI 3) on the left, acupuncture at Houxi (SI 3) on the left, Wangu (SI 4) on the left and Dazhui (GV 14) were given respectively. One intervention was given and the needles were retained for 30 min in each group. 30 min before and after acupuncture, the infrared thermal images of the face were collected, and the facial temperature was compared among the following 5 acupoints, i.e. Yintang (GV 24⁺), Suliao (GV 25), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24). RESULTS: After acupuncture, the facial temperature at Yintang (GV 24⁺) and Chengjiang (CV 24) was increased compared before acupuncture in the sham-acupuncture group (P<0.01, P<0.05). The facial temperature at Suliao (GV 25) in the Houxi group was reduced after acupuncture (P<0.05). In the Wangu group, the temperature at Yintang (GV 24⁺) was increased compared before acupuncture (P<0.01). The facial temperature was increased at Duiduan (GV 27) and Chengjiang (CV 24) compared before acupuncture in the Dazhui group (P<0.01, P<0.05). The differences of facial temperature at Chengjiang (CV 24) and Suliao (GV 25) after acupuncture were larger than before acupuncture in the Houxi group and the Dazhui group (P<0.01). In comparison with the temperature at Suliao (GV 25) of the same group, the differences of facial temperature before and after acupuncture at Yintang (GV 24⁺), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24) were increased in the Houxi group (P<0.01, P<0.05); while, the increase was also obtained at Yintang (GV 24⁺), Shuigou (GV 26), Duiduan (GV 27) and Chengjiang (CV 24) in the Dazhui group (P<0.05, P<0.01). The difference of facial temperature at Yintang (GV 24⁺) before and after acupuncture was increased compared with Suliao (GV 25) in the Wangu group (P<0.05). CONCLUSION Acupuncture at Houxi (SI 3) generates a similar thermal effect as Dazhui (GV 14). It regulates and dissipates the core temperature to "govern the yang qi of the whole body".

Objectives: To evaluate the distribution by age and sex of serum high-sensitivity C-reactive protein (hsCRP) in an urban Chinese population and to provide a profile prediction for the risk of bacterial infection, inflammatory diseases, or tissue damages in the body. Methods: Serum hsCRP was determined using the Roche Tina-quant immuno-turbidimetric assay on a Hitachi 7600-010 automatic biochemical analyzer (Roche Diagnostics) in 1,572 males and 1,800 females, including 78 pregnant women, who were derived from the National Health and Nutrition Survey in 2010-2012. Results: The average hsCRP concentration in urban China was 0.68 mg/L for males and 0.65 mg/L for females. Significant differences in hsCRP were found among different age groups ( < 0.05). Monitoring results showed no significant differences among the 6-11, 45-59, and ≥ 60-year-old groups in the comparison of hsCRP between males and females in large cities. However, hsCRP concentration was significantly higher in men aged 12-17 and 18-44 years than in women. Conclusion The distribution of the hsCRP status of residents in large cities in China was influenced by age and gender, and the hsCRP levels of both sexes increased gradually with age. In addition, hsCRP concentration was higher in healthy pregnant women than in non-pregnant women. Basing on our results, we recommend that this parameter be included in future national and international screening for early detection of various illnesses.

OBJECTIVETo explore the early detection of breast cancer by ultrasonic imaging and thermal tomography of luciferase or green fluorescent protein (GFP)-labeled MDA-MB-231 breast cancer cell line-xenografts in nude mice.

METHODSFluorescence-tagged lentiviral vectors were transfected into the triple-negative breast cancer cell line MDA-MB-231. These cells were implanted either subcutaneously under the right breast pad or intravenously into the tail vein of nude BALB/C mice. Thermal tomography and ultrasound imaging were used to detect tumor formation and to monitor tumor growth and metastasis in vivo.

RESULTSTriple negative breast cancer cell line-xenografts were used to successfully construct an orthotopic nude mice model of breast cancer metastasis in the peritoneum. Thermal tomography and ultrasound imaging were used together to detect small tumors. Thermal tomography imaging detected small tumors earlier than ultrasound imaging.

CONCLUSIONSThermal tomography can be used to monitor changes in tumor growth and detect abnormal tissue. Therefore, it can serve as a convenient,rapid,sensitive, and reliable technique for early screening of human breast cancer.

Retinal vein occlusion ( RVO ) is a common vascular disease of the retina and is one of the main reasons for blindness. ln recent years, there have been some new understanding about the diagnosis and treatment of the disease, especially some new researches about treatment,for example ,in the therapy of the intravitreal injection of triamcinolone acetonide and anti-VEGFs as well as dexamethasone implant ( Ozurdex ) . This article will make a brief summarization of the progress about the diagnosis and treatment of RVO.

Wuxistatin, a novel and potent statin, is converted from lovastatin by Amycolatopsis sp. CGMCC1149. In the bioconversion, lovastatin is firstly hydroxylated by a hydroxylase. To obtain the critical hydroxylase, a novel hydroxylase gene was isolated from Amycolatopsis sp. CGMCC1149 by Degenerate PCR and Self-Formed Adaptor PCR and expressed in Escherichia coli. BLAST sequence analysis revealed that the gene belonged to cytochrome P450 gene superfamily and could encode a 403-amino-acid protein with a molecular weight of 44.8 kDa. The secondary structure prediction result showed that this protein contained many typical functional regions of P450, such as oxygen binding site, ion-pair region and heme binding region. Meanwhile, a catalytic function verification system was constructed by NADH, ferredoxin and ferredoxin reductase which could catalyze lovastatin hydroxylation into the target product. These would be helpful for further studies in large-scale production of wuxistatin.

OBJECTIVETo observe the efficacy and safety of oral propranolol in the treatment of periorbital proliferating phase infantile hemangioma.

METHODSA retrospective review of patient medical records was performed. 12 patients (9 female, 3 male; 1.5-8.5 months, average 3.3 months) with periorbital proliferating phase infantile hemangioma underwent oral propranolol therapy. The dosage was slowly increased to 2 mg/kg daily in divided doses for a mean duration of 16 weeks (range 4 weeks-41 weeks). Therapeutic outcomes and safety were established by evaluating colour, size of lesion, duration of treatment and side-effects of treatment before and after treatment.

RESULTSOf these, 9 had a signification reduction in colour and size of the lesions, 2 had no further growth. 1 is stopped therapy due to hypotension after drug administration. 11 other patients, although mild adverse effects were noted, no symptoms were severe enough to discontinue treatment.

CONCLUSIONSPropranolol appears to be a safe and effective treatment in the management of periorbital proliferating phase infantile hemangioma.

BACKGROUNDDrug-eluting stents (DES) have been shown to significantly reduce clinical events and angiographic restenosis in the treatment of coronary artery disease (CAD). This study was conducted to assess the long-term efficacy and safety of the polymer-based sirolimus-eluting cobalt-chromium Firebird 2 stents in the treatment of patients with CAD.

METHODSThis first-in-man study using the Firebird 2 stent is a prospective, historically-controlled multicenter clinical study, which enrolled 67 patients with CAD who were treated with the sirolimus-eluting cobalt-chromium stent (Firebird 2, Microport Shanghai, Firebird 2 group), compared to another 49 patients treated with a bare cobalt alloy stent (Driver, Medtronic, control group). Continued 2-year clinical follow-up was performed after getting the initial 6-month angiographic and 1-year clinical follow-up. The incidence of major adverse cardiac events (MACE) including cardiac death, reinfarction and target lesion revascularization (TLR) and stent thrombosis were compared between the two groups.

RESULTSAll patients in the Firebird 2 group (100.0%) and 48 patients in the control group (98.0%) completed the 2-year clinical follow-up. At the 1-year follow-up the use of the Firebird 2 stent was highly effective, resulting in a significant 94% decrease of TLR (26.5% in the control group and 1.5% in the Firebird 2 group, P<0.0001). A significant difference in TLR was maintained at 2-year follow-up, Firebird 2 group 1.5% and the control group 31.3% (P<0.0001). Between 1- and 2-year post-stenting, no more TLR occurred in the Firebird 2 group compared with two cases in the control group (P>0.05). There was a 1.5% incidence of MACE at 1- and 2-year follow-up in the Firebird 2 group, compared with 26.5% and 33.3% in the control group, respectively (all P<0.0001). The cumulative 1- and 2-year MACE free survival rates were 98.5% in the Firebird 2 group vs 73.5% and 66.7% in the control group (log rank P<0.0001). No case of stent thrombosis occurred during 2-year follow-up in the Firebird 2 group, compared with one case that suffered a definite stent thrombosis in the control group at 19-month post-stenting: this patient presented with unstable angina pectoris and was treated by balloon angioplasty.

CONCLUSIONSCompared with the bare cobalt alloy stent, the Firebird 2 sirolimus-eluting cobalt-chromium stent is safe and effective in treating patients with CAD. The use of this stent was associated with a sustained clinical benefit and significantly lower rate of TLR and MACE up to 2 years post-stenting.
