Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE. Of 5 271 non-surgical patients, the incidence of VTE was 2.201%(116/5 271), including an incidence of 0.114%(6/5 271) of PE. PE accounted for 5.172%(6/116) of non-surgical patients with VTE. There was no significant difference in the incidence of VTE or PE between surgical patients and non-surgical patients ( χ2=1.20, 0.05, P>0.05). (2) Treatment and outcomes of patients with VTE. Among 175 EC patients with VTE, 163 cases underwent drug treatment, and 12 cases did not receive treatment. Among 163 cases with drug therapy, 158 cases underwent anticoagulant therapy, 5 cases were treated with thrombolysis. All the 163 patients were improved and discharged from hospital. Conclusions:The incidence of VTE in patients with EC is relatively low, as 2.069%. There is no significant difference in the incidence of VTE or thrombus type between surgical EC patients and non-surgical EC patients.

Objective:To investigate the toxic effect of chlorambucil combined with ibrutinib on mantle cell lymphoma(MCL)cell line Jeko-1 and its related mechanism.Methods:The MCL cell line Jeko-1 was incubated with different concentrations of chlorambucil or ibrutinib or the combination of the two drugs,respectively.CCK-8 assay was used to detect the proliferation of the cells,and Western blot was used to measure the protein expression levels of BCL-2,caspase-3,PI3K,AKT and P-AKT.Results:After Jeko-1 cells were treated with chlorambucil(3.125,6.25,12.5,25,50 μmol/L)and ibrutinib(3.125,6.25,12.5,25,50 μmol/L)alone for 24,48,72h respectively,the cell proliferation was inhibited in a time-and dose-dependent manner.Moreover,the two drugs were applied in combination at low doses(single drug inhibition rate＜50％),and the results showed that the combination of two drugs had a more significant inhibitory effect(all P＜0.05).Compared with the control group,the apoptosis rate of the single drug group of chlorambucil(3.125,6.25,12.5,25,50 μmol/L)and ibutinib(3.125,6.25,12.5,25,50 μmol/L)was increased in a dose-dependent manner.The combination of the two drugs at low concentrations(3.125,6.25,12.5 μmol/L)could significantly increase the apoptosis rate compared with the corresponding concentration of single drug groups(all P＜0.05).Compared with control group,the protein expression levels of caspase-3 in Jeko-l cells were upregulated,while the protein expression levels of BCL-2,PI3K,and p-AKT/AKT were downregulated after treatment with chlorambucil or ibrutinib alone.The combination of the two drugs could produce a synergistic effect on the expressions of the above-mentioned proteins,and the differences between the combination group and the single drug groups were statistically significant(all P＜0.05).Conclusion:Chlorambucil and ibrutinib can promote the apoptosis of MCL cell line Jeko-1,and combined application of the two drugs shows a synergistic effect,the mechanism may be associated with the AKT-related signaling pathways.

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

Due to various constraints, such as clinical implementation conditions and unique characteristics of acupuncture-moxibustion, some randomized controlled trials (RCTs) of acupuncture-moxibustion still suffer from relatively low quality and limited applicability. The single-arm objective performance criteria/performance goal can be considered as an ideal supplementary and alternative research approach to RCTs. In this paper, the feasibility of applying the single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical research is explored from the limitations of conducting acupuncture-moxibustion RCTs, the principles, the essential design considerations and key statistical steps. In addition, illustrative examples are provided. The objective is to offer insights into resolving practical difficulties in acupuncture-moxibustion clinical research.

OBJECTIVE: To investigate the characteristics of ¹⁸F-FDG PET/CT images of multiple myeloma secondary extramedullary infiltration in order to improve recognition. METHODS: Twenty-one patients with multiple myeloma secondary extramedullary infiltration confirmed by pathology or follow-up from January 2012 to October 2020 in the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed. All the patients underwent ¹⁸F-FDG PET/CT imaging before treatment, and the PET/CT characteristics of extramedullary infiltration and bone marrow were analyzed. RESULTS: Twenty-one patients included 12 males and 9 females, aged from 41 to 77 years old, with an average of 58.3±10.0; 9 cases of extramedullary infiltration involving lymph nodes; lung, stomach, spleen, and kidney were involved respectively in 2 cases; retroperitoneal, right auricle, subcutaneous nodule, and spinal meninges involvement were reported in each one case respectively. The maximum SUVmax value of extra-medullary lesions was 21.2, the minimum value was 2.1, and mean was 7.7±5.3. The maximum SUVmax value of bone marrow was 33.5, the minimum was 2.4, and mean was 6.6±3.6. There was no statistically significant difference in SUVmax value between extra-medullary lesions and bone marrow (Z=-1.195, P=0.232). CONCLUSION ¹⁸F-FDG PET/CT not only has a good diagnostic value for multiple myeloma, but also a good evaluation value for secondary extramedullary infiltration, which provides reference for clinical treatment and prognosis.

Objective:To investigate MRI texture features reflecting short-term medial femoral cartilage variations after anterior cruciate ligament (ACL) reconstruction.Methods:A retrospective case series analysis was conducted referring to the data of 20 patients who received ACL reconstruction at First Affiliated Hospital of Fujian Medical University from January 2017 to January 2020 including 17 males and 3 females, aged 23-43 years [(32.1±5.4)years]. The patients were evaluated before operation and at 1, 4, 12, 24, 48 weeks after operation: (1) the region of interest (ROI) in medial femoral cartilage was divided into ROI1 (meniscus anterior horn cartilage), ROI2 (meniscus body cartilage) and ROI3 (meniscus posterior horn cartilage) according to MRI image acquisition of the affected knee. The texture feature parameters were extracted for screening and analyzing to obtain the parameters reflecting sensitivity to cartilage variations; (2) the level of urinary C-telopeptide of type II collagen (uCTX-II) was measured by ELISA. At different time points, differences in texture feature parameters were compared to screen the parameters most sensitive to cartilage variations, and uCTX-II level were compared as well. Then, Pearson correlation analysis was used to determine the correlation between texture feature parameters most sensitive to cartilage variations and uCTX-II level.Results:After screening and analyzing, the horizontal direction of gray level non-uniformity (Horzl_GlevNonU) and Skewness of histogram (Skewness) of ROI3 were selected as sensitive texture feature parameters reflecting sensitivity to cartilage variations. There were significant difference in the Horzl_GlevNonU and Skewness of ROI3 before operation and at 1, 4, 12, 24, 48 weeks after operation (all P<0.05). Meanwhile, the Horzl_GlevNonU and Skewness of ROI3 were gradually increased over time, with a more significant tendency in the Horzl_GlevNonU. The Horzl_GlevNonU of ROI3 was similar at 4 weeks and 12 weeks after operation ( P>0.05), with significant differences at other time points (all P<0.05). The Skewness of ROI3 was significantly different at 1 week and 48 weeks after operation ( P<0.05), with insignificant differences at other time points (all P>0.05). The Horzl_GlevNonU of ROI3 was selected as the most sensitive texture feature parameter reflecting cartilage variations. Significant difference was reported in uCTX-II level before operation and at 1, 4, 12, 24, 48 weeks after operation (all P<0.05). After Pearson correlation analysis, the Horzl_GlevNonU of ROI3 was positively correlated with uCTX-II level before operation and at 1, 4, 12, 24, 48 weeks after operation ( r=0.554, 0.596, 0.550, 0.632, 0.756, 0.514, P<0.05 or 0.01). Conclusion:The Horzl_GlevNonU of ROI3 is the most sensitive texture feature parameter that reflects the early variations of medial femoral cartilage after ACL reconstruction and is positively correlated with uCTX-II level.

Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder among children. The theory of traditional Chinese medicine (TCM) does not have a special term of this disease, and classifies ADHD to the category of " forgetfulness" " dysphoria" " injudiciousness" according to its clinical manifestations. TCM theoretic and clinical systems for treating ADHD have been developed, but current pharmacodynamics studies of TCM on ADHD have mostly focused on neurotransmitter metabolic system and its receptor signaling pathway to reflect the advantages of multi-component and multi-target effect of TCM, but failed to demonstrate the scientific connotations of TCM theory, such as " coordination between kidney and brain" and " steady Yin and vexed Yang" , and ignored the delay in cortical maturation as the core neuropathology of ADHD. The symptoms relating to " restlessness of Yang" due to Yin deficiency that cannot inhibit hyperactivity of Yang, kidney-Yin deficiency and liver-Yang excess syndrome is the most common syndrome of ADHD, and TCMs with effect of invigorating kidney and filling sea of marrow are mostly used by TCM practitioners. According to anatomy basis of neuronal development disorder, the new theory of " energy metabolism dysfunction" , the pathogenesis hypothesis of sea of marrow development disorder and its relevant clinical practices and experimental studies, substantial basis studies of the therapy for " invigorating kidney and filling sea of marrow" , as well as pharmacodynamics study of Rehmannia glutinosa (Shudihuang) for treating ADHD, we put forward ADHD pathogenesis that " restlessness of Yang due to Yin deficiency" is related to the disorder of executive function due to the delay in cortical maturation, energy metabolism dysfunction and neurodevelopmental disorder, and regarded that TCMs with effect of invigorating kidney and filling sea of marrow are the most commonly used to treat ADHD, and improve delay in cortical maturation corresponding to sea of marrow insufficiency by regulating dysfunction of neurodevelopment and energy metabolism, so as to relieve the core symptoms of ADHD. The new treatment model of TCM with effect of invigorating kidney and filling sea of marrow for treating ADHD will provide a theoretical basis for improving the clinical efficacy of ADHD.

Objective To investigate the risk of Anisakis infections among high-risk populations along the coastal areas of Jiangsu Province, so as to develop the strategy for the prevention and control of anisakiasis in the province. Methods Three counties along the coastal areas of Jiangsu Province were selected as the study sites in 2018, including Rudong County in Nantong City, Haizhou District in Lianyungang City and Dongtai City in Yancheng City. The knowledge, attitude and practice (KAP) of anisakiasis prevention and control, and the prevalence of serum specific IgG antibody against Anisakis were investigated among high-risk populations among these three study sites, including fishermen, fish seller and people who liked eating fresh and live marine fish. Factors affecting the prevalence of the specific IgG antibody against Anisakis were identified using a multiple logistic regression model. In addition, Anisakis larvae infections were detected in fresh and live marine fish samples collected from local markets, and the prevalence and intensity of Anisakis infections were estimated. Results A total of 625 high-risk populations were investigated, including 349 men (55.8%). Only 13.0% of the subjects heard about anisakiasis, and a low awareness rate of anisakiasis prevention and control knowledge was seen among these three types of high-risk populations. There were 21.6% of the subjects eating raw or half-cooked marine fish, 5.8% eating undercooked marine fish, 3.2% presenting vomiting, nausea and diarrhea after eating marine fish, 5.1% developing systemic allergic symptoms, and 65.6% using the same chopping board for raw and cooked food. The sero-prevalence of the anti-Anisakis IgG antibody was 7.0% among the study subjects. Multiple logistic regression analysis identified education level [OR = 0.687, 95% CI (0.478, 0.987)] and development of systemic allergic symptoms [OR = 4.641, 95% CI(1.411, 15.268)]as factors affecting the positive anti-Anisakis IgG antibody among the study subjects. Among 494 fresh and live marine fish detected, the prevalence and intensity of Anisakis larvae infection was 64.0% and 8.1 larvae per fish, with high prevalence seen in Trichiurus haumela and Pneumatophorus japonicas. Conclusions The awareness of anisakiasis prevention and control knowledge is low among the high-risk populations living along the coastal areas of Jiangsu Province, and there are high-risk behaviors, such as eating raw or half-cooked food, using the same chopping board for raw and cooked food. In addition, the prevalence of Anisakis infections is high in the marine fish in these areas. Therefore, the health education and health promotion for anisakiasis prevention and control should be intensified.
