Objective To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022, so as to provide insights into formulation of echinococcosis control measures in the prefecture. Methods Villagers were randomly sampled using a multistage sampling method from class I and II echinococcosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococcosis, while all patients undergoing ultrasound examinations in medical institutions in class III endemic counties received active echinococcosis screening. In addition, livestock in centralized slaughterhouses or slaughtering sites were screened for echinococcosis using the palpation and necropsy method, and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs. The trends in detection of human and livestock echinococcosis, detection of newly diagnosed human echinococcosis cases and detection of Echinococcus coproantigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022. Results The mean detection rate of human echinococcosis was 0.13% (540/407 803) in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022, which appeared a tendency towards a decline over years (χ²_trend = 1 217.21, P < 0.001), and the highest detection of newly diagnosed echinococcosis cases was seen in Hejing County (0.28%, 191/67 865). The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 147.02, P < 0.001), with the highest detection rate seen in Hejing County (3.44%, 86/2 500), and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 302.46, P < 0.001), with the highest detection rate in Qiemo County (2.74%, 118/4 313). Conclusions The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022; however, there is still a high echinococcosis transmission risk in local areas. Sustainable integrated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.

Objective:To explore the efficacy and adverse reactions of image-guided hypofractionated intensity-modulated radiotherapy (Ig-HypoRT) conbined with contralateral esophageal protection in treatment of patients with unresectable stage Ⅲ non-small cell lung cancer (NSCLC).Methods:The clinical data of 45 patients with unresectable stage Ⅲ NSCLC who were admitted to Xuzhou Cancer Hospital from January 2016 to January 2019 were retrospectively analyzed. Patients received induction chemotherapy with a platinum-based dual-drug combination regimen, followed by Ig-HypoRT with a total dose of tumor of 60-63 Gy/12- 18 times at 3.5-5.0 Gy/time. Contralateral esophagus was delineated as an organ at risk during radiotherapy, limiting V 45 Gy≤1.8 cc and V 55 Gy ≤0.4 cc. Patients' efficacy, survival and the occurrence of adverse reactions were observed. Results:Among 45 patients, there were 9 cases of complete remission, 31 cases of partial remission, 4 cases of stable disease and 1 case of disease progression, and the effective rate was 88.8% (40/45). The median follow-up time was 34 months, 45 patients had a median overall survival (OS) time of 25.0 months (95% CI 21.7-28.8 months), with 1-, 2-, and 3-year OS rates of 78.9%, 56.8% and 47.7%, respectively; the median progression-free survival (PFS) time was 18.5 months (95% CI 15.0-22.0 months), with 1-, 2- and 3-year PFS rates of 59.8%, 32.6% and 18.6%, respectively. The 3-year local recurrence rate was 9% (4/45). The incidence of grade 1-2 radioactive esophagitis was 80% (36/45); the incidence of grade 1-2 chest pain was 20% (9/45). The incidence of grade 3-4 adverse reactions were 13% (6/45), including 7% (3/45) of grade 3 pulmonary atelectasis, 4% (2/45) of grade 3 radioactive pneumonia, and 2% (1/45) of grade 4 hemoptysis. Conclusions:Ig-HypoRT combined with contralateral esophageal protection for unresectable stage Ⅲ NSCLC can improve survival rate and reduce esophageal adverse reactions of patients.

Heart failure is the end stage of multiple cardiovascular diseases, which can easily form venous thromboembolism (VTE) due to the combination of vascular wall injury, hypercoagulable state and decreased blood flow velocity. VTE is an important cause of death in patients with heart failure. By adopting active VTE prevention strategies, the rehospitalization rate and incidence of VTE in patients can be reduced, and the health outcomes of patients can be improved. This article summarizes the incidence, mechanism, risk factors, preventive measures, evaluation tools, and nursing measures of heart failure combined with VTE, in order to provide reference for preventing VTE in heart failure patients.

Radiation-induced brain injury (RBI) is one of the complications after radiotherapy for head and neck malignant tumors, which seriously affects the quality of life of patients. The pathophysiological mechanism of RBI is not completely clear. Current studies suggest that it is involved in a variety of cells in the central nervous system (CNS), whereas astrocyte, as the largest number of glial cells in the CNS, plays an important role in maintaining the CNS homeostasis and responding to CNS injury. In this article, the role of astrocytes in RBI was reviewed.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation， endangering human health and life. Currently， there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix， generating vascular factors， affecting epithelial-mesenchymal transformation， or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance （MDR） are the regulation of membrane proteins， apoptosis-regulated gene expression， enzyme-mediated multidrug resistance， DNA damage repair， and epithelial-stromal transformation， resulting in ineffective treatment of tumors. Therefore， the search for natural， safe， and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment， researchers have conducted more extensive studies on its monomers and compounds. In addition， the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion， metastasis， and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore， they can also improve the tolerance of patients to chemotherapy drugs， relieve side effects of chemotherapy， reduce the chance of recurrence， and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis， reversing drug resistance， prolonging the prognosis of cancer patients， improving their quality of life， and prolonging their survival time. Currently， various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis， and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion， anti-metastasis， and anti-tumor resistance therapy in recent years， in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.

Objective:To observe the effects of cervical region Ⅱ and oral target area optimization on therapeutic efficacy, salivary gland function and oral mucosal response during intensity modulated radiation therapy (IMRT) for oropharyngeal cancer.Methods:A total of 50 patients with oropharyngeal squamous cell carcinoma in Xuzhou Cancer Hospital from January 2012 to May 2017 were collected. According to the random number table, they were divided into normal radiotherapy group (the control group), oral and cervical target area optimization group (the observation group), 25 cases in each group. Both groups were treated with IMRT and platinum-chemotherapy. The control group received bilateral cervical region Ⅱ-Ⅳ lymphatic drainage area irradiation (the positive side of the cervical lymph node included Ⅰ B region), and bilateral cervical region Ⅱ was given a tumor dose of 60 Gy (positive lymph nodes were given intensified irradiation); the observation group was optimized for the target area, and the contralateral cervical region Ⅱ B (the side with no positive lymph node) was given a tumor dose of 50 Gy; the observation group's oral structure was delineated as an organ at risk and the average radiation dose (D mean) was limited to <32 Gy. The differences in radiation dose of parotid gland, acute oral mucosal reaction and long-term xerostomia (6 months after the end of radiotherapy), objective remission rate (ORR), local recurrence rate (LRR), 3-year overall survival (OS) were compared between the two groups. Results:In the control group, the contralateral parotid gland D mean was (29±4) Gy, the proportion of irradiation volume exposed to 34 Gy (V 34) was (48±5)%; in the observation group, contralateral parotid gland D mean was (23±3) Gy, V 34 was (41±5)%, and there are statistically significant differences between the two groups ( t values were 6.14, 4.98, all P < 0.05). In the control group, oral D mean was (35±6) Gy, the proportion of volume exposed to 30 Gy (V 30) was (36±5)%; in the observation group oral D mean was (29±4) Gy, V 30 was (28±4)%, and there were statistically significant differences between the two groups ( t values were 4.11, 5.98, all P < 0.05). The incidence of ≥ grade Ⅱ acute oral mucosal adverse reaction and the duration time of oral mucosal ≥ 2 weeks was 64% (16/25) and 76% (19/25), respectively in the control group, 36% (9/25) and 40% (10/25), respectively in the observation group; and the differences were statistically significant ( χ2 values were 3.92, 6.65; P values were 0.048, 0.009). The incidence of ≥ grade Ⅱ long-term xerostomia reaction was 72% (18/25) and 44% (11/25), respectively in the control group and the observation group, and the difference between the two groups was statistically significant ( χ2 = 4.02, P = 0.044). The ORR, LRR, and 3-year OS rates were 80%, 28%, 48% in the control group, and 76%, 24%, 44% in the observation group. There was no statistically significant difference in the OS between the two groups ( χ2 = 0.04, P = 0.849). Conclusions:Optimization of the target area of the oral and cervical region Ⅱ during IMRT for oropharyngeal carcinoma can improve the function of salivary glands, thereby reducing dry mouth and oral mucosal reactions, improving the quality of life of patients; and it does not affect the efficacy of tumor treatment.

Objective:To explore the effect of holistic nursing combined with heat preservation nursing in patients undergoing thoracoscopic lung wedge resection.Methods:From April 2020 to March 2021, convenience sampling was used to select 196 patients who underwent thoracoscopic wedge resection for lung cancer in the First Affiliated Hospital of Xinjiang Medical University as the research object. The patients were divided into the observation group and the control group by the order of admission, 98 cases in each group. The patients in the control group were given routine nursing, and the patients in the observation group were given holistic nursing combined with heat preservation nursing on the basis of the control group. The visual analogue scale (VAS) was used to evaluate the postoperative pain of the two groups of patients, and the transfer time to and from the Resuscitation Room, postoperative recovery time and hospital stay were compared between the two groups. The incidence of postoperative adverse reactions in the two groups was recorded and compared.Results:The VAS scores of the observation group at 1 and 12 hours after operation were (2.06±0.52) and (2.46±0.81) respectively, which were lower than those of the control group [ (3.72±1.10) and (4.06±0.78) ], and the differences were statistically significant ( P<0.05) . The postoperative recovery time, hospital stay, and transfer time to and from the Resuscitation Room of the observation group were (56.34±10.10) min, (7.12±1.17) d, (2.10±0.32) min, and (2.52±0.50) min, respectively, lower than those of the control group, and the differences were statistically significant ( P<0.05) . The incidence of adverse reactions in the observation group (4.08%) was lower than that in the control group (22.45%) , and the difference was statistically significant ( P<0.05) . Conclusions:Holistic nursing combined with heat preservation nursing can speed up the postoperative recovery, reduce the incidence of adverse reactions, relieve postoperative pain, and facilitate postoperative recovery of patients undergoing thoracoscopic lung wedge resection.

Objective:To provide a normal reference range for anogenital distance (AGD) in full-term neonates and to investigate factors possibly affecting neonatal AGD.Methods:Neonates with gestational age ≥37 weeks who were delivered in the Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from November 2017 to March 2019 were enrolled.General information on mothers and newborns were collected and neonatal AGD were measured.The distance from the male anus center to the base of the scrotum was determined to be the male AGD, and the distance from the female anus center to the posterior labia was recorded as the female AGD.The effects of maternal and neonatal factors on neonatal AGD were analyzed.Results:A total of 1 078 newborns were included, including 586 males and 492 females.Male AGD [(22.90±3.80) mm] was significantly greater than female AGD [(11.80±2.10) mm] ( t=22.316, P<0.05). The AGD of singleton neonates was significantly greater than that of neonatal twins [males: (23.01±3.82) mm vs.(21.18±1.88) mm, females: (11.89±2.08) mm vs.(10.98±1.75) mm, t=26.185, 18.326, all P<0.05]. Neonatal gestational age, birth weight, head circumference and length were significantly associated with AGD (all P<0.05). Maternal factors (including age, height, weight, body mass index, gravidity, parity, occupation, etc.) were not significantly associated with neonatal AGD (all P>0.05). The AGD of 10 children with genital malformation was significantly smaller than that of males with normal genital appearance [(22.89±1.99) mm vs.(23.55±3.78) mm]( t=15.362, P=0.006). Conclusions:The reference ranges of AGD in full-term males and females in Shanghai are(22.90±3.80) mm and (11.80±2.10) mm, respectively.The neonatal gestational age, birth weight, head circumference and length may be the intrinsic factors affecting neonatal AGD.

Objective:To determine the characteristics of hospitalized newly diagnosed systemic lupus erythematosus (SLE) patients with high disease activity, and identify the risk factors.Methods:Data from 194 newly diagnosed SLE patients at Shanghai Renji Hospital between May 2013 and December 2018 were collected retrospectively. All patients were followed up for 1 year or until death. Patients' demographic, clinical, and laboratory characteristics on admission and medication history were retrospectively collected as baseline data. Patients were divided into two groups, lupus patients with infection (51 cases) and lupus patients without infection (143 cases). The method of univariate analysis of data depended on the data distribution type. Variables that suggested association in the univariate analysis ( P<0.05) were entered into Cox regression model. Results:Among 194 patients with newly diagnosed SLE, 21 cases (11%) died and 51 cases (26%) were infected during 1-year follow-up. Regarding the infection site, 34 cases (67%) had lung infection, 9 cases (18%) had central nervous system infection and 9 cases (18%) had blood stream infection. Common bacteria were identified in 19 cases (45%), followed by fungal infection in 18 cases (43%) and mycobacterium infection in 7 cases (17%). Among the 51 patients with infection, 38 patients (75%) had infection within the first 3 months after diagnosis, and mortality in this group was significantly higher than that in the uninfected group (39%, 15/38 vs 2%, 3/143 , P<0.01). Comparing baseline parameters between patients with 3-month infection and without, significant differences ( P<0.05) were detected in age (≥40 years), systemic lupus erythematosus disease activity index (SLEDAI) score (>10 points), Systemic Lupus International Collaborating Clinic (SLICC)/American College of Rheumatology(ACR) systemic lupus erythematosus damage index (SDI) (≥1 point), pericardial effusion, nephritis, gastrointestinal vasculitis, diabetes, lymphocyte count <0.8×10 9/L platelet count <100×10 9/L, serum creatinine >104 mmol/L and serum globulin level <20 g/L. Finally, clinically meaningful candidate predictors were included in the Cox regression model and it showed that lymphocyte count <0.8×10 9/L, nephritis and gastrointestinal vasculitis were independently predictive for 3-month infection in new-onset lupus patients. Conclusion:Understanding disease spectrums and risk factors of infection in newly diagnosed SLE patients will help clinicians to manage those patients with infection effectively to achieve favorable prognosis.
