Objective: To compare the efficacies between open surgery and axillary non-inflatable endoscopic surgery in papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was performed on 343 patients with unilateral PTC treated by traditional open surgery (201 cases) and transaxillary non-inflating endoscopic surgery (142 cases) from May 2019 to December 2021 in the Head and Neck Surgery of Sichuan Cancer Hospital. Among them, 97 were males and 246 were females, aged 20-69 years. 1∶1 propensity score matching (PSM) was performed on the enrolled patients, and the basic characteristics, perioperative clinical outcomes, postoperative complications, postoperative quality of life (Thyroid Cancer-Specific Quality of Life), aesthetic satisfaction and other aspects of the two groups were compared after successful matching. SPSS 26.0 software was used for statistical analysis. Results: A total of 190 patients were enrolled after PSM, with 95 cases in open group and 95 cases in endoscopic group. Intraoperative blood losses for endoscopic and open groups were [20 (20) ml vs. 20 (10) ml, M (IQR), Z=-2.22], postoperative drainage volumes [170 (70)ml vs. 101 (55)ml, Z=-7.91], operative time [135 (35)min vs. 95 (35)min, Z=-7.34], hospitalization cost [(28 188.7±2 765.1)yuan vs. (25 643.5±2 610.7)yuan, x¯±s, t=0.73], postoperative hospitalization time [(3.1±0.9)days vs. (2.6±0.9)days, t=-3.24], and drainage tube placement time [(2.5±0.8) days vs. (2.0±1.0)days, t=-4.16], with statistically significant differrences (all P<0.05). There was no significant difference in surgical complications (P>0.05). There were significant diffferences between two groups in the postoperative quality of life scores in neuromuscular, psychological, scar and cold sensation (all P<0.05), while there were no statistically significant differences in other quality of life scores (all P>0.05). In terms of aesthetic satisfaction 6 months after surgery, the endoscopic group was better than the open group, with statistically significant difference (χ²=41.47, P<0.05). Conclusion: Endoscopic thyroidectomy by a gasless unilateral axillary approach is a safe and reliable surgical method, which has remarkable cosmetic effect and can improve the postoperative quality of life of patients compared with the traditional thyroidectomy.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

OBJECTIVETo further study the characteristics of drugs with neutral property in two-way application and conditioned dominance by observing the action characteristic of 10 traditional Chinese medicines with neutral property in hemorheological indicators of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats.

METHODThe model of heat stagnation and blood stasis syndrome rats was established by injecting carrageenan and dry yeast, while the model of cold stagnation and blood stasis syndrome rats was established by body freezing. Subsequently, 10 traditional Chinese medicines with neutral property, 5 traditional Chinese medicines with heat property and 5 traditional Chinese medicines with cold property were selected for intervention to observe the changes in such indicators as whole blood viscosity, plasma viscosity and hematocrit and analyze the action characteristics of drugs with neutral property.

RESULTANOVA showed that among six of the 10 traditional Chinese medicines with neutral property, including Typhae Pollen, Sarcandrae Herba and Sappan lignum, could obviously increase the hemorheological indicators of both heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome rats; five traditional Chinese medicines with cold property, such as Salviae Miltiorrhizae Radix et Rhizoma, Leonuri Herba, Rhei Radix et Rhizoma, could significantly ameliorate the hemorheological indicators of heat stagnation and blood stasis syndrome rats (P < 0.01 or P < 0.05), and Salvia Miltiorrhiza Radix et Rhizoma alone could ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.05); all of the five traditional Chinese medicines with heat property could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats (P < 0.01), among which Carthami Flos and Notoginseng Radix et Rhizoma could significantly ameliorate the hemorheological indicators of cold stagnation and blood stasis syndrome rats. According to the average high-shear blood viscosity analysis, drugs with neutral property showed similar action characteristics to those with cold property in ameliorating hemorheology indicators of heat stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity; and traditional Chinese medicines with neutral property have the similar action characteristics to those with heat property in improving the hemorheology indicators of cold stagnation and blood stasis syndrome rat and better effect than those with heat property in reducing whole blood viscosity.

CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with cold property; but under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property show the similar action characteristics to those with heat property. This indicates that traditional Chinese medicines with neutral property show both heat and cold properties under he conditions of heat stagnation and blood stasis syndrome and cold stagnation and blood stasis syndrome.

BACKGROUNDMycobacterium abscessus (M. abscessus) can cause a variety of human infections, involving the lung, skin and soft tissues, and is generally believed to be acquired from environmental sources. The aim of this study was to investigate the molecular diversity and antibiotic susceptibility of M. abscessus isolates as the basis for strategies to improve control and management of infection.

METHODSSeventy M. abscessus isolates from patients attending the Guangzhou Thoracic Hospital were identified from 2003 to 2005 by biochemical tests, gas chromatography, polymerase chain reaction (PCR)-restriction analysis (PRA) of heat shock protein gene hsp65, and sequencing of the quinolone resistance determining regions (QRDRs) of gyrA. Susceptibilities to six antibiotics were determined by micro-broth dilution. Isolates were genotyped using randomly amplified polymorphic DNA (RAPD) analysis.

RESULTSMost isolates (63/70; 90%) were susceptible to amikacin but rates of susceptibility to other antibiotics varied from moderate, clarithromycin (60%) and imipenem (43%), to low for ciprofloxacin and ofloxacin (3%), and 87% of isolates had intermediate susceptibility to cefoxitin. RAPD analysis showed that the 70 clinical isolates displayed 69 unique RAPD patterns.

CONCLUSIONSThe high genetic diversity of isolates suggests that they are not transmitted from person to person but, presumably, are acquired independently from environmental sources. M. abscessus isolates displayed variable levels of susceptibility to all antibiotics tested, other than amikacin, indicating a need for routine susceptibility testing to guide treatment.

OBJECTIVETo study the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property by observing the action characteristic of 10 traditional Chinese medicines capable of promoting blood circulation and removing blood stasis with neutral property in the microcirculation in rats with heat stagnation and blood stasis syndrome.

METHODThe rat model with heat stagnation and blood stasis syndrome was established by injecting carrageenan and dry yeast, and the rat model with cold stagnation and blood stasis syndrome was built by the body freezing method. Ten traditional Chinese medicines with neutral property, including 5 with hot property and 5 with cold property, were selected for intervention to observe blood flow rate and flow state indicators in rat auricles and make a comparative analysis on action characteristics of traditional Chinese medicines with neutral property.

RESULTANOVA showed that among the 10 traditional Chinese medicines with neutral property, 6 such as Typhae Pollen, Sappan Lignum and Vaccariae Semen can obviously increase the blood flow rate (P < 0.01 or P < 0.05) in the above two models; all of the 5 traditional Chinese medicines with cold property can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat model with heat stagnation and blood stasis syndrome, but only Salvia miltiorrhiza can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, while other medicines showed no notable effect; among the 5 traditional Chinese medicines with hot property, Carthamus tinctorius and Ligusticum chuanxiong can increase the blood flow rate (P < 0.01 or P < 0.05) in the rat models with cold stagnation and blood stasis syndrome, but had no obvious effect to the blood flow rate in the rat models with heat stagnation and blood stasis syndrome. According to the analysis on average blood flow rate, traditional Chinese medicines with natural and cold properties showed similar effect on heat stagnation and blood stasis syndrome and better effect in increasing blood flow rate than those with hot property; those with natural and hot properties showed similar effect and better effect in increasing blood flow rate than those with cold property.

CONCLUSIONUnder the condition of heat stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with those with cold property; wile under the condition of cold stagnation and blood stasis syndrome, traditional Chinese medicines with neutral property have the similar action characteristics with the Chinese medicinal herbs with hot property. This indicates the action characteristics of "two-way application and conditioned dominance" of traditional Chinese medicines with neutral property to some extent.

OBJECTIVETo investigate the effect of multidrug resistance-associated protein 4 (MRP4) expression on the radiosensitivity of colorectal carcinoma cell lines in vitro.

METHODSThe vector of shRNA for RNA interference was constructed and then transfected into HCT116 cell line to steadily down-regulate the expression of MRP4. HCT116 cells were divided into 3 groups including the CON group(non-transfected), NC group (negative control virus was added), and KD group (RNAi target was added for transfection). To test the effectiveness of RNA interference, real-time polymerase chain reaction and Western blot were used to measure the expression pattern of MRP4 at both mRNA and protein levels, respectively. For the examination of the effect of RNA interference of MRP4 on the radiosensitivity, flow cytometry was used to calculate the rate of apoptotic cells 24 h after 4 Gy radiation. Proliferation of the cells was measured via MTT assay at different time points.

RESULTSShRNA plasmid was successfully constructed. Transfection of this constructed vector into HCT116 cell line caused steady silencing of MRP4 expression (HCT116-KD). MRP4 mRNA and protein expression were significantly down-regulated following RNA interference(P<0.05). Twenty-four hours after radiation, the apoptosis rate of KD cell line was (71.7±0.8)%, significantly higher than that in the CON group [(56.1±0.9)%] and NC group[(59.8±0.8)%](P<0.05). Fourty-eight hours and 72 hours after radiation, the proliferation was significantly inhibited in KD cells compared to the control groups(P<0.05).

CONCLUSIONSExpression of MRP4 is closely related to radio-tolerance of colorectal carcinoma. Down-regulation of MRP4 expression by RNA interference enhances radiosensitivity of colorectal carcinoma cell lines in vitro. MRP4 may be an effective molecular marker for predicting the radiosensitivity of colorectal carcinoma.

Welder's siderosis was traditionally described as "benign pneumoconiosis" because of the absence of associated symptoms, functional impairment or pulmonary fibrosis. Although several authors have reported evidence of fibrosis in the lungs of welders, siderosis with local massive fibrosis has been rarely described. In this paper, we present a case of Welder's siderosis with local massive fibrosis mimicking lung cancer.

Objective To investigate the clinical feature,treatment,and prognosis of hospitalized patients with jaw osteoradionecrosis. Methods A total of 93 cases with jaw osteoradionecrosis treated between 2000 and 2010 was reviewed.Of the 93 cases,79 cases were with mandible lesions,13 cases with maxillary lesions,and 1 case with both mandible and maxillary lesions.Sixty-six cases received one course of radiotherapy,with the radiation doses of 34 -90 Gy (mean 64.6 Gy).Twenty-two cases experienced tooth extraction or other operative procedures before exhibition of the clinical symptoms for osteoradionecrosis.The interval time between radiotherapy and the onset of osteoradioneerosis varied from 2 weeks to 32 years (mean 54 months).Results Of 93 cases,56 patients underwent radical resection of the pathologic bone and reconstruction with free tissue flaps,in whom 7 cases received the second surgery due to microvascular thrombosis in flap vessels,and flaps were survival by new vascular anastomosis in 3 cases,the failed flaps were removed and replaced successfully by non vascularized bone grafts in 2 cases,and the failed flaps removed and the defects were repaired with adjacent skin in other 2 cases.In the 56 cases,only one case was with disease recurrence and 53 cases with significant improvement in chewing and swallowing functions.Only 2 of 93 cases underwent resection of the pathologic bone and reconstruction with titanium plates,and thereafter they encountered titanium exposure.Scaling of osteoradionecrosis lesions was applied to 20 of 93 patients and 9 cases of them were with disease recurrence.Fifteen cases had resection of the effected mandible without reconstruction.Disease relapse was encountered in 2 of them,others had poor chewing and swallowing.Conclusions The mandible is more susceptible to osteoradionecrosis than maxilla.Radical resection with reconstruction by free tissue flap is recommended for the treatment of jaw osteoradionecrosis,and scaling and reconstruction only with titanium plate should be avoided because of high risks of titanium exposure and disease relapse.

Objective To observe the effects of improved whole course nursing care for patients under cerebral angiography operation.Methods 136 patients under cerebral angiography operation between January,2011 and March,2012 were selected for the study and randomly divided into experimental group and control group with 68 cases in each group.The comparison group was treated with traditional nursing care.Except the traditional nursing care,experimental group received improved whole course nursing care.Anxiety scores before and after the operation and postoperative complications were compared between the two groups.Results According to the selfrating anxiety scale,there was no significant difference in preoperative anxiety scores ( t =0.08,P ＞0.05 )between two groups.However,significant difference was observed in postoperative anxiety scores,(11.05 ±2.46 )for the experimental group and (13.92 ± 2.43 ) for the control group (t=6.84,P ＜0.05 ).Postoperative complications were also found significant different between two groups,7.35％ and 33.80％ for the experimental group and control group respectively ( x2 =14.57,P ＜0.05 ).Conclusions Improved whole course nursing care can minimize side effects and fasting time, ease patients' anxiety, reduce stress responses and postoperative complications,increase the success rate of operations and enhance patients' degree of satisfaction.It is worth of clinic application.
