ABSTRACT
OBJECTIVE@#To understand the clinical and epidemiological characteristics of human ocular thelaziasis patients in China.@*METHODS@#Case reports regarding human ocular thelaziasis cases in China were retrieved in international and national electronic databases, including CNKI, VIP, CBM, Traditional Chinese Medical Literature Analysis and Retrieval System, Wanfang Database, PubMed and Web of Science from 2011 to 2022. Patients' gender, age, clinical symptoms, treatment, recurrence, site of infections, time of onset, affected eye, affected sites, number of infected Thelazia callipaeda, sex of T. callipaeda and source of infections were extracted for descriptive analyses.@*RESULTS@#A total of 85 eligible publications were included, covering 101 cases of human ocular thelaziasis, including 57 males (56.44%) and 44 females (43.56%) and aged from 3 months to 85 years. The main clinical manifestations included foreign body sensation (56 case-times, 22.49%), eye itching (38 case-times, 15.26%), abnormal or increased secretions (36 case-times, 14.46%), tears (28 case-times, 11.24%) and eye redness (28 case-times, 11.24%), and conjunctival congestion (50 case-times, 41.67%) was the most common clinical sign. The most common main treatment (99/101, 98.02%) was removal of parasites from eyes using ophthalmic forceps, followed by administration with ofloxacin and pranoprofen. In publications presenting thelaziasis recurrence, there were 90 cases without recurrence (97.83%) and 2 cases with recurrence (2.17%). Of all cases, 51.96% were reported in four provinces of Hubei, Shandong, Sichuan, Hebei and Henan, and ocular thelaziasis predominantly occurred in summer (42.19%) and autumn (42.19%). In addition, 56.45% (35/62) had a contact with dogs.@*CONCLUSIONS@#The human thelaziasis cases mainly occur in the continental monsoon and subtropical monsoon climate areas such as the Yellow River and the Yangtze River basin, and people of all ages and genders have the disease, with complex clinical symptoms and signs. Personal hygiene is required during the contact with dogs, cats and other animals, and individual protection is required during outdoor activities to prevent thelaziasis.

Objective:To investigate the clinical outcome and influencing factor of one-anastomosis duodenal switch (OADS) for obesity.Methods:The retrospective cohort study was conducted. The clinical data of 104 obesity patients who underwent OADS in the China-Japan Union Hospital of Jilin University from October 2018 to June 2021 were collected. There were 42 males and 62 females, aged 33(range, 18?66)years. The clinical outcome of each patient was evaluated using Textbook Outcome (TO). Observation indicators: (1) treatment situations for patients; (2) TO situa-tions; (3) analysis of factors affecting postoperative TO. Follow-up was conducted using outpatient examination or telephone interview to detect postoperative complication of patients up to November 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using chi-square test. Multivariate analysis was conducted using the binary Logistic regression model. Results:(1) Treatment situations for patients. All 104 patients under-went OADS without conversion to laparotomy or death of patient. The operation time and duration of postoperative hospital stay of the 104 patients were (187±39)minutes and 6(range, 4?55)days, respectively. Two of the 104 patients were readmitted. The experiences of surgeons on OADS was (53±30)cases. There were 82 patients underwent OADS using the Da Vinci robotic surgical system, while there were 22 patients underwent OADS using laparoscopic surgery system. The complication rate of 104 patients was 7.69%(8/104). Cases with stage Ⅱ, stage Ⅲb and stage Ⅳ complications of the Clavien Dindo classification were 5, 2 and 1, respectively. (2) TO situation. Of the 104 patients, 62 cases achieved TO, while 42 cases did not achieve TO. The operation time, retention time of abdominal drainage tube, duration of postoperative hospital stay, experiences of surgeons on OADS, number of OADS for surgeons using Da Vinci robotic surgical system were (166±26)minutes, 0(range, 0?7)days, 6(range, 4?7)days, 62±28, 54 in patients achieved TO, versus (218±34)minutes, 3 (range, 0?11)days, 8(range, 5?55)days, 38±27, 28 in patients not achieved TO, showing significant differences in the above indicators between them ( t=?8.81, Z=?3.63, ?5.33, t=4.27, χ2=6.27, P<0.05). Cases with complications were 0 in patients achieved TO, versus 8 in patients not achieved TO, showing a significant difference between them ( P<0.05). (3) Analysis of factors affecting postoperative TO. Results of multivariate analysis showed that the experiences of surgeons on OADS was an independent influencing factor for postoperative TO in patients undergoing OADS ( odds ratio=1.04, 95% confidence interval as 1.01?1.06, P<0.05). Conclusions:OADS is safe and feasible for obesity patients with low postoperative complication incidence and satisfactory clinical outcome.

ABSTRACT
Objective:To compare the optimal gridpercutaneous vertebroplasty (PVP) and conventional PVP in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods:A retrospective cohort study was conducted of 102 patients with OVCFs who had underwent PVP between May 2016 and May 2019 at department of spine surgery, General Hospital of Northern Theater Command. According to the different surgical methods, they were divided into the optimalgrid PVP group (102 cases) and conventional PVP group (94 cases). In the optimal grid PVP group, there were 38 males and 64 females with an average age of 67.3±8.5 years old, and the course of disease was 2.3±1.2 days; the injured sites were lumbar vertebra, including 59 cases of L 1 vertebra, 31 cases of L 2 vertebra, 8 cases of L 3 vertebra, 3 cases of L 4 vertebra and 1 case of L 5 vertebra. In the conventional PVP group, there were 26 males and 68 females with an average age of 71.5±5.6 years old, and the course of disease was 2.1±1.1 days; the injured sites were lumbar vertebra, including 52 cases of L 1 vertebra, 33 cases of L 2 vertebra, 7 cases of L 3 vertebra and 2 cases of L 4 vertebra. The patients were prepared before operation. Then the best puncture point was selected, and the guide wire and working channel were inserted. Finally the bone cement was pushed. The operation time, intraoperative fluoroscopy times, bone cement dosage and bone cement leakage were compared between the two groups. Visual analogue scale (VAS), anterior heights and median heights of injured vertebra were compared between the two groups at postoperative 3 days, 3 months and the final follow-up. Results:There were no significant differences in the general clinical data between the two groups before operation ( P>0.05). All patients had no complications such as wound infection,pulmonary embolism,spinal cord embolism or death. The operation time, fluoroscopy times, bone cement dosage and bone cement permeability of the two groups were statistically significant different ( P<0.05), and the optimal grid group was better than the conventional group. VAS at 3 days, 3 months and the final follow-up was statistically significantlower in the optimal grid group than the conventional group ( P<0.05). There was no significant difference in the recovery of the anterior and middle edge heights of injured vertebra in the two groups 3 days after operation ( P>0.05), but there were statistical significant difference between the two groups3 months after operation and at the last follow-up ( P<0.05), whilethe optimal grid group was better than the conventional group. Conclusion:Compared with conventional PVP, the optimal grid PVP is safer and more effective in the treatment of osteoporotic vertebral compression fractures.
ABSTRACT
Tripartite motif (TRIM) family proteins are important effectors of innate immunity against viral infections. Here we identified TRIM35 as a regulator of TRAF3 activation. Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon (IFN) in response to viral infection. Trim35-deficient mice were more susceptible to influenza A virus (IAV) infection than were wild-type mice. TRIM35 promoted the RIG-I-mediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1. IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3. TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2, thereby antagonizing its suppression of TRAF3 activation. Our in vitro and in vivo findings thus reveal novel roles of TRIM35, through catalyzing Lys63- or Lys48-linked polyubiquitination, in RIG-I antiviral immunity and mechanism of defense against IAV infection.

Objective@#To investigate the clinical efficacy of laparoscopic stomach intestinal pylorus sparing surgery (SIPS) in the treatment of severe obesity.@*Methods@#The retrospective and descriptive study was conducted. The clinical data of 5 patients with severe obesity who were admitted to the China-Japan Union Hospital Affiliated to Jilin University from October to November 2018 were collected. There was 1 male and 4 females, aged from 18 to 55 years, with an average age of 33 years. All the 5 patients underwent laparoscopic SIPS. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was performed by outpatient examination, telephone interview and Wechat up to February 2019, including general condition, changes in body weight, body mass index, waistline, blood pressure, percentage of excess weight loss, fasting plasma glucose, glycosylated hemoglobin, blood lipid, and uric acid at 3 months after surgery. Measurement data with normal distribution were represented as Mean±SD, and they were tested with Hotelling T2 test. Measurement data with skewed distribution were represented as M (range).@*Results@#(1) Surgical situations: 5 patients underwent successfully laparoscopic SIPS under clear surgical field, without obvious bleeding, conversion to open surgery or perioperative death. The operation time was 240 minutes (range, 165-345 minutes). (2) Postoperative situations: the time to initial out-of-bed activity, time to first and flatus, and time to initial drinking and liquid intake were 2 days (range, 2-3 days), 3 days (range, 2-3 days), and 3 days (range, 3-4 days), respectively. On the third day after surgery, all the 5 patients were confirmed anastomotic patency, without gastric leakage, stenosis, or obstruction by upper gastrointestinal contrast. The abdominal drainage-tube was removed on the fourth day after feeding without obvious discomfort and foreign substances extraction from the drainage-tube. The duration of postoperative hospital stay was 6 days (range, 6-7 days). (3) Follow-up: 5 patients with severe obesity were successfully followed up for 3 months. During the follow-up, one patient had significantly increased frequency of defecation, roughly 5-8 times a day, especially after eating greasy food. According to the dietary guidance of the case manager, diarrhea was improved significantly after reducing the intake of oily food. Of the 5 patients with severe obesity, color doppler ultrasonography examination revealed that cholestasis was found in 2 patients at 3 months after operation, which may be related to significant weight loss, ratio imbalance of bile acid to and cholesterol, intestinal microbiota, injury of vagus nerve, significant increasing in mucin of gallbladder, and without oral ursodeoxycholic acid as prescribed by the doctor. The body weight, body mass index, waistline, systolic blood pressure, and diastolic blood pressure of 5 patients with severe obesity were (100±15)kg, (36±4)kg/m2, (111±10)cm, (130±12)mmHg (1 mmHg=0.133 kPa), and (78±14)mmHg at 3 months after operation, respectively, showing significant differences compared with these of preoperation (F=61.631, 75.558, 87.045, 9.501, 16.248, P<0.05). The percentage of excess weight loss was 44%±9%. Among the 5 patients with severe obesity, the fasting plasma glucose of 2 patients with type 2 diabetes mellitus decreased from 9.55 mmol/L and 13.49 mmol/L to 5.18 mmol/L and 5.62 mmol/L after operation, respectively. Level of glycated hemoglobin decreased from 10.0% and 9.9% to 5.2% and 6.2% after operation, respectively. In the 2 patients with hyperlipidemia, one patient with hypertriglyceride had level of triglyceride, total cholesterol, and low density lipoprotein increased from preoperative 2.24 mmol/L, 4.84 mmol/L and 2.92 mmol/L to 2.47 mmol/L, 6.68 mmol/L and 5.51 mmol/L after operation, another patient with hypercholesterol had cholesterol level decreased from preoperative 5.97 mmol/L to postoperative 5.75 mmol/L after operation. In the 3 patients with hyperuricemia, two patients had the uric acid decreased from 404 μmol/L and 484 μmol/L to 319 μmol/L and 417 μmol/L after operation, respectively, one had the uric acid increased from 531 μmol/L to 674 μmol/L after operation.@*Conclusions@#Laparoscopic SIPS has a significant short-term effect on patients with severe obesity, but its long-term safety and efficacy need to be further followed up.

ABSTRACT
Objective:To investigate the protective effects of acupuncture pretreatment on ischemic myocardium,the protective mechanism of acupuncture pretreatment on ischemic myocardium was explored by observing the cardiac muscle cell apoptosis and the expression of HSP70 mRNA of ischemia-reperfusion injury rats treated with acupuncture pretreatment.Methods:Sixty-four Wistar rats were randomly divided into eight groups:control group,sham surgery group,ischemia-repertusion group,ischemia pretreatment group,manual acupuncture pretreatment group(once a day),electroacupuncture pretreatment group(once a day),manual acupuncture pretreatment group(twice a day),and electroacupuncture pretreatment group(twice a day).The reperfusion model of rat myocardial ischemia was made.Expression of HSP70 mRNA was assayed by in situ hyrbridization,and cell apoptosis by TUNEL.Results:Compared with those in the control group and the sham surgery group,the apoptosis and the expression of HSP70 mRNA were increased in the ischemia-reperfusion group.Compared with those in the ischemia-reperfusion group,the cardiac muscle cell apoptosis was decreased and the HSP70 mRNA was increased in the rats treated with acupuncture pretreatment;meanwhile,acupuncture pretreatment twice a day had stronger effects than acupuncture pretreatment once a day and ischemia pretreatment.Conclusion:Acupuncture pretreatment can inhibit the cardiac muscle cell apoptosis,and up-regulate the expression of HSP70 mRNA in ischemia-reperfusion rats.Acupuncture pretreatment twice a day has stronger effects than pretreatment once a day.
ABSTRACT
OBJECTIVE To set-up safe alternatives to ethidium bromide(EB).METHODS Comparative analysis was performed on the DNA staining efficiencies of 4 fluorescent dyes including SYBR Gold,SYBR Green Ⅰ,(GoldView) and EB in preparative agarose gel electrophoresis.RESULTS Although both SYBR Gold and SYBR Green Ⅰ altered electrophoretic mobility and thus DNA size estimates,they were cost-effective alternatives to EB.SYBR Gold was more sensitive than SYBR Green Ⅰ at detecting short fragments,but 50 bp bands were clearly(visible) using either dye when visualized with a long integration time.CONCLUSIONS SYBR Gold or SYBR Green Ⅰ are sensitive and relatively safe alternatives to EB.

OBJECTIVE To search a method for identifying Clostridium perfringens and genotyping their toxin for gene diagnosis by multiplex PCR.METHODS The mutiplex PCR was developed with three sets of primers(designed) based on the sequences of three C.perfringens toxin genes(CP?,CP? and CPE) published in GenBank to identify C.perfringens and genotype their three toxin genes.RESULTS Three expected(sequences) were (obtained) successfully by multiplex PCR and identified by electrophoresis.CONCLUSIONS The(specific) sequences of C.perfringens could be amplified and their three genes of toxins could be identified by this multiplex PCR(system).Such method should be helpful for developing gene diagnosis well.
ABSTRACT
OBJECTIVE To discuss a highly effective method to immobilize probe on the surfaces of piezoelectric DNA sensors.METHODS Pseudomonas aeruginosa probe was immobilized on the gold surface of gene sensor(array) with routine self-assembly method(SAM)(non-reduction method) and SAM with deoxidized probe((reduction) method),respectively.The changes in frequency and time-cost were compared in reactions with(different) concentrations of probe.RESULTS Reduction method had the advantage of more probe immobilization;less time consumed in testing and higher changes in frequency during the reaction than non-reduction method.CONCLUSIONS Reduction method has a better ability to immobilize probe on the surfaces of piezoelectric DNA sensors.
ABSTRACT
Objectives:To investigate the relationship between calcitonin gene-related peptide(CGRP) in rat dental pulp and tooth movement.Methods:The first maxillary molars in 36 SD rats were moved mesially by orthodontic force,18 were examined 3,7 and 14 day after application of the appliance whereas another 18 rats were observed 7,14 and 28 days after removal of the appliance respectively.6 control rats were without treatment.Then,CGRP immunoreactivity was demonstrated by indirect immunoflurescence on frozen sections of dental pulp samples.Results:3,7 and 14 days after application of orthodontic force, the CGRP containing nurve fiber counts in each pulp were 17.57?4.42,24.04?3.55 and 21?4.11 respectively,those in the control pulps were 8.03?4.49. 7,14 and 28 days after removal of the appliance, the counts were 19.23?5.23,18.23?5.08 and 8.12?5.01 respectively.Conclusions:CGRP immunoreactive nerve fibres may take an active part in tissue responses in pulp tissues during experiment tooth movement.
