ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

Objective To evaluate the efficacy of XELOX regimen as neoadjuvant chemotherapy in the treatment of stage Ⅱ and Ⅲ colon cancer.Methods The clinical data of 50 patients with clinical stage Ⅱ(T4)Ⅲ colon cancer who underwent laparoscopic radical resection at general surgery department of our hospital from January 1,2012 to January 1,2021 were retrospectively analyzed.Patients were divided into neoadjuvant chemotherapy group(NACT)and adjuvant chemotherapy group(ACT)according to whether they received neoadjuvant chemotherapy with XELOX regimen.The general clinical data,adverse reactions of chemotherapy,surgical complications,operation time,intraoperative blood loss,hospitalization time,hospitalization cost,negative conversion rate of tumor markers,tumor remission rate,tumor downstaging rate,tumor response grade after chemotherapy,postoperative disease-free survival curve,and overall survival curve were retrospectively analyzed and compared among the groups.Results There were no significant differences in operative complications,postoperative exhaust time and hospital stay between NACT group and ACT group(P＞0.05).The adverse reactions of chemotherapy,the negative conversion rate of postoperative CEA and CA19-9,the duration of operation,the amount of bleeding,and the hospitalization cost in NACT group were significantly better than those in ACT group(P＜0.05).In terms of DFS and OS survival curves,with the extension of time,the decline of the NACT survival curve was smaller than that of the ACT group,and there was a significant difference in DFS survival curve(P＜0.05),but no significant difference in OS survival curve(P＞0.05).Conclusion XELOX neoadjuvant chemotherapy is safe and effective in the treatment of stage Ⅱ(T4)and stage Ⅲcolon cancer.

Objective:To investigate the effects of antibacterial absorbable suture closure in the repair of small range of bone defect wounds due to deep sternal wound infection after median thoracotomy.Methods:This study was a retrospective non-randomized clinical controlled study. A total of 32 patients (20 males and 12 females, aged (58±11) years) who met the inclusion criteria and underwent closure with antibacterial absorbable sutures (hereinafter referred to as direct closure surgery) admitted to Guangdong Provincial People's Hospital of Southern Medical University (hereinafter referred to as our hospital) from October 2017 to December 2021 were included in direct closure group. A total of 39 patients (27 males and 12 females, aged (59±11) years) who met the inclusion criteria and received bilateral pectoralis major muscle flap packing repair admitted to our hospital from January 2015 to January 2020, were included in muscle flap packing group. In the two groups, sternal infected wounds were thoroughly debrided during stage Ⅰ surgery, followed by wound repair during stage Ⅱ surgery. The width of sternal cross-section defects after debridement was less than 1 cm for patients in the two groups. For patients in direct closure group, stage Ⅱ wound repair involved intermittent sutures to the anterior sternal plate or full-thickness sternum with a total of 6 or 7 double sternal sutures. Relevant data including the duration of the stage Ⅱ wound repair surgery and the volume of blood loss during surgery, length of hospital stay, and bacterial wound infection of patients in the two groups were recorded. The postoperative complications and wound healing of patients in the two groups were recorded. During follow-up, the wound infection or recurrence of patients in the two groups and the sternal healing of patients in direct closure group were observed.Results:Compared with those in muscle flap packing group, the duration of stage Ⅱ wound repair surgery and length of hospital stay of patients in direct closure group were significantly shorter (with t values of 13.61 and 6.25, respectively, P<0.05), and there was no statistically significant difference in intraoperative blood loss volume of the stage Ⅱ wound repair surgery between the two groups ( P>0.05). The main bacterial infection in the two groups was Staphylococcus. In direct closure group, one patient had exudation in the wound two weeks post-operation, however the wound healed well after two weeks of conservative dressing changes; the wounds of the other patients healed well. In muscle flap packing group, 5 patients had postoperative complications, of which one patient died, and the wounds of 4 patients healed after dressing change or reoperation; the wounds of the other patients healed well. There was no statistically significant difference in complication incidence of patients between the two groups ( P>0.05). During the follow-up of 22-45 months, there was no re-infection or recurrence in the wound of patients in direct closure group and surviving patients in muscle flap packing group, the sternum of patients in the direct closure group achieved anatomical union. Conclusions:Direct closure surgery can not only effectively repair sternal cross-sectional defects with width below 1 cm due to deep sternal wound infections after median thoracotomy, but can also significantly shorten the operation time and duration of hospitalization.

Objective:To compare the efficacy of transcatheter arterial embolization (TAE) with laparotomy in the treatment of severe liver injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 48 patients with severe liver injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from December 2013 to June 2020, including 28 males and 20 females; aged 16-75 years [(45.7±6.2)years]. There were 25 patients with grade III, 15 grade IV and 8 grade V according to the American Association for the Surgery of Trauma (AAST) classification. After general treatments such as infusion and hemostasis, TAE was performed in 26 patients (TAE group) and laparotomy in 22 patients (laparotomy group). The operation time and length of hospital stay were compared between the two groups. Erythrocyte, hemoglobin and serum creatinine were compared before operation and at postoperative 1 day. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed before operation and at postoperative 1, 3, 7 days. Complications were observed.Results:All patients were followed up for 12-60 months [(17.1±9.1)months]. The operation time and length of hospital stay were (65.7±9.2)minutes and (21.6±6.6)days in TAE group, significantly shorter than (162.5±28.1)minutes and (31.5±7.4)days in laparotomy group ( P<0.05 or 0.01). There was no significant difference between the two groups referring to erythrocyte, hemoglobin and serum creatinine before operation and at postoperative 1 day (all P>0.05). There was no significant difference in ALT and AST between the two groups before operation (all P>0.05). TAE group showed ALT level of 1 154(884, 1 698)U/L, (975.3±400.9)U/L and (403.4±232.9)U/L at postoperative 1, 3, 7 days, significantly lower than 2 053(1 965, 2 132)U/L, (1 604.1±188.2)U/L and (915.3±160.5)U/L in laparotomy group (all P<0.05). TAE group showed AST level of (1 313.2±542.0)U/L, 525(302, 971)U/L and 174(84, 324)U/L at postoperative 1, 3, 7 days, significantly lower than (1 962.9±245.4)U/L, 1 478(1 089, 1 677)U/L and 837(674, 1 006)U/L in laparotomy group ( P<0.05 or 0.01). The complication rate was 26.9% (7/26) in TAE group, significantly lower than 59.1% (13/22) in laparotomy group ( P<0.05). Conclusion:For severe liver injury, TAE can significantly shorten operation time and length of hospital stay, accelerate the recovery of liver function and reduce the complication rate in comparison with laparotomy.

Objective:To explore the risk factors of pneumoconiosis patients' re-admission to provide a scientific basis for improving the treatment effect of pneumoconiosis, reducing the rate of re-admission, and reducing the burden of disease.Methods:In June 2020, The clinical data of 470 patients with pneumoconiosis who had hospitalization records from February 8, 2014, to February 8, 2020, in the Hunan Provincial Occupational Disease Prevention and Treatment Institute were retrospectively analyzed. The patients' general data and emotional state at the first admission were collected through questionnaires and telephone follow-ups. The entire group of patients completed at least one follow-up, with readmission as the end event. First, the Kaplan-Meier method was used for univariate analysis. The multivariate COX regression model analysis was performed on meaningful variables to explore the risk factors that affect the patient's re-admission.Results:A total of 470 patients with pneumoconiosis were included in this study, with an average age of 55.88 years (34-81 years old) and all the participants were male. During the first admission, the number of participants diagnosed as stage III pneumoconiosis, with complications of COPD, fatty liver, or severe pulmonary diffusion dysfunction was 215 (45.74%) , 179 (38.09%) , 51 (10.85%) , and 44 (9.36%) , respectively. Six patients (1.28%) have had suicidal tendencies almost every day since they became ill. A total of 345 patients (73.40%) were re-admitted to the hospital. Multivariate Cox regression model analysis showed that compared with the suspected pneumoconiosis group, patients in the first, second, and third-stage pneumoconiosis groups had an increased risk of readmission ( OR=2.43, 2.96, 2.35, P=0.000) . Compared with the age of 30-50 years old, 50-70 years old and ≥70 years old have an increased risk of readmission ( OR=1.28, 2.32, P<0.05) . Patients with tricuspid regurgitation ( OR=1.33, P<0.05) and elevated triglyceride level (>2.26 mmol/L) ( OR=1.40, P<0.05) have increased risks of readmission. Compared with the normal group, patients with severe pulmonary diffusion dysfunction in pneumoconiosis have an increased risk of readmission ( OR=1.96, P<0.05) . Compared with the normal group, pneumoconiosis patients in the suicidal group had an increased risk of re-admission to the hospital almost every day ( OR=2.92, P<0.05) . Conclusion Age of onset, stage of pneumoconiosis, tricuspid regurgitation, high triglycerides, severe diffuse pulmonary dysfunction, and suicidal tendency are independent risk factors that affect the readmission of patients with pneumoconiosis. The management of chronic diseases and mental health of patients with pneumoconiosis should be strengthened to reduce the risk of readmission. Conclusion:Age of onset, stage of pneumoconiosis, tricuspid regurgitation, high triglycerides, severe diffuse pulmonary dysfunction, and suicidal tendency are independent risk factors that affect the readmission of patients with pneumoconiosis. The management of chronic diseases and the mental health of patients with pneumoconiosis should be strengthened to reduce the risk of readmission.

Objective:To recognize the characteristics of necrotizing fasciitis patients complicated with sepsis and summarize the experience the treatment.Methods:A retrospective study was conducted. The clinical data of 57 patients with necrotizing fasciitis complicated with sepsis admitted to Guangdong Provincial People's Hospital from July 2009 to December 2019 was analyzed by collecting such factors as gender, age, complications, infection sites, pathogens, surgery information, treatment options and outcome. The patients were divided into debridement group ( n = 14) and control group ( n = 43) according to whether the debridement was completed within 48 hours of admission, and the mortality during hospitalization between the two groups was compared. A telephone follow-up had been done to record the long-term outcome of these patients. Results:Among 57 patients with necrotizing fasciitis complicated with sepsis, there were 43 males and 14 females with the average age of (57.9±12.1) years old. Most of the underlying diseases were diabetes mellitus (70.17%), other diseases included hypertension (8.77%), tumor chemotherapy (7.02%), liver disease (hepatitis, cirrhosis, 7.02%), coronary artery heart disease (3.51%), systemic lupus erythematosus (3.51%), etc. Most of the infection site was lower limbs (71.93%). There were 78 pathogens cultured in 57 patients, in which 52 were non-drug resistant bacteria (66.67%), and 26 were drug resistant bacteria (33.33%). There were 40 Gram positive (G +) bacteria (51.28%), 29 Gram negative (G -) bacteria (37.18%), 8 fungi (10.26%) and 1 mixed bacteria (1.28%). Finally, of 57 patients, 46 patients were cured, and 11 patients died with hospital mortality of 19.30%. Among 57 patients, the hospital mortality in the debridement group was significantly lower than that in the control group [0% (0/14) vs. 25.58% (11/43), P < 0.05]. Among the 46 cured patients, 11 had accepted amputations, accounting for 23.91%. In December 2020, 43 patients who were cured (3 patients were lost to follow-up) were followed up by telephone. Twenty-three patients were completely self-care, 9 patients were partly self-care, 8 patients were completely unable to take care of themselves, and 3 patients died. Conclusions:Necrotizing fasciitis with sepsis mostly occurs in people with weakened immunity, and has a high mortality and disability rate. Early identification and active surgical debridement may be the key to improve the treatment effect.

Objective:To understand the infection status of key human parasites in Yantai City, Shandong Province, and to provide scientific basis for establishing strategy for prevention and control of the disease.Methods:According to the "National Investigation Plan of Human Parasitic Infection Status" and implementation rules, stratified cluster random sampling method was adopted to select 39 survey sites in 10 counties (cities, districts) of Yantai City from 2015 to 2019. The respondents were residents in each survey site, with no less than 200 people in each survey site. The modified garten thick smear method (one fecal two test) and the direct smear method were respectively used to detect the eggs of intestinal worms and the trophozoites or cysts of intestinal protozoa. Besides, the transparent adhesive paper anal swab was used to detect pinworms in children aged 3 - 9 years. SPSS 18.0 software was used for statistical analysis. Comparison between infection rates was analyzed by χ 2 test or Fisher's exact probability test with 0.05 of test level. Results:A total of 8 507 people were investigated from 2015 to 2019. The total infection rate of intestinal parasites was 1.75% (149/8 507), and no protozoa was detected. A total of 4 species of intestinal worms were detected, including 1.41% (120/8 507) of whipworm, 0.16% (14/8 507) of ascaris, 0.14% (12/8 507) of pinworm and 0.07% (6/8 507) of hookworm. Among 149 cases of worm infection, 3 cases were ascaris and whipworm mixed infection, accounting for 2.01%. The infection rate of pinworm was 1.90% (11/578) in 578 children aged 3 - 9 years detected by transparent adhesive paper anal swab. From 2015 to 2019, the incidence of intestinal parasites infection first increased and then decreased, the difference was statistically significant (χ 2 = 469.38, P < 0.05). The infection rates of male and female were 1.72% (70/4 071) and 1.78% (79/4 436), respectively, with no significant difference between them (χ 2 = 0.05, P > 0.05). There was a significant difference of intestinal parasites infection rate in different age groups (χ 2 = 23.34, P < 0.05). The infection rate of intestinal parasites in ≥80 years old group was the highest with 2.84% (8/282). There was a significant difference of intestinal parasites infection rate among different professionals (χ 2 = 41.71, P < 0.05). Intestinal parasites infection rate of farmers was the highest with 2.58% (113/4 388). There was a significant difference of intestinal parasites infection rate among people with different cultural degree(χ 2 = 51.91, P < 0.05). Infection rate of illiterate people was the highest with 4.98% (16/321). Parasitic infection was detected in 10 counties (cities, districts), except Laishan District. The highest infection rate was Haiyang City (10.18%, 102/1 002), and the results of other counties (cities, districts) were lower than 1.20%. There was significant difference in infection rate in different regions (χ 2 = 433.87, P < 0.05). The infection rate in urban area was 0.51% (22/4 281), and the infection rate in rural area was 3.01% (127/4 226). The difference between urban and rural areas was statistically significant (χ 2 = 76.70, P < 0.05). Conclusion:The infection rate of intestinal parasites has been reduced to a lower level in rural area of Yantai City, and farmers are the key prevention and control population of intestinal parasites infection, so attention should be paid to strengthen the publicity of parasitic disease prevention and control.

Objective To investigate the changes of hypoxia-inducible factor (HIF-1α, HIF-2α) expression level in lung cancer A-549 cells under normoxic conditions, different hypoxia durations, and different oxygen concentrations. Methods A549 cells were divided into normoxic group, time control group, and oxygen concentration control group. Western blot was used to detect the expression of HIF-1α and HIF-2α in A-549 cells.Results The expression of HIF-1α and HIF-2α protein were lower under normoxia and significantly increased under hypoxic conditions. The difference was statistically significant. The lower the oxygen concentration, the more HIF-1α and HIF-2α protein expression levels were. The differences between high and high were statistically significant. The expression of HIF-1α protein increased at 2 h after hypoxia, peaked at 8 h, appeared plateau at 8 to 16 h, and decreased at 32 h, with a statistically significant difference. HIF-2α proteins gradually increased with prolonged hypoxia. Conclusions Under hypoxic conditions, the expression of HIF-1α and HIF-2α are increased, and the expression of HIF-2α has a time-dependent pattern, which may have more important biological significance.
