Objective:
To evaluate the effectiveness for the construction of the "mosquito-free village" in Jinzishan Village, Fuling District, Chongqing Municipality, so as to provide references for improving mosquito control practices in hilly and mountainous rural areas.
Methods:
The "mosquito-free village" initiative in Fuling District was launched in April 2023. Mosquito density monitoring was conducted annually from April to October. Larval mosquito density was monitored using the path method and scoop-catch method, and adult mosquito density was monitored using human-baited landing catch. One hundred and fifty-two villagers were randomly conducted before the "mosquito-free village" construction (April 2023) and one hundred and sixty-seven villagers were randomly conducted after the construction (November 2024). Knowledge awareness rate and correct behavioral practices regarding mosquito control among villagers were assessed. The satisfaction among villagers were evaluated in November 2024. The effectiveness of the initiative was evaluated based on mosquito density data, health education outcomes from 2023 to 2024, and satisfaction.
Results:
The average larval mosquitoes path index in Jinshanzi Village decreased from 1.50 spots/km in 2023 to 0.07 spots/km in 2024 (P<0.05). The average sampling spoon index of larval mosquitoes decreased from 3.43% in 2023 to 0 in 2024. The average landing rate index of adult mosquitoes decreased from 3.90 mosquitoes/(person·time) in 2023 to 0.38 mosquitoes/(person·time) in 2024 (P<0.05). The awareness rate of mosquito control knowledge and the formation rate of correct behaviors among villagers increased from 59.87% and 57.24% in 2023 to 92.22% and 90.42% in 2024, respectively (both P<0.05). In 2024, the satisfaction of villagers was 92.81%.
Conclusion
The mosquito density, health education effectiveness, and satisfaction of villagers in Jinzishan Village have all met the evaluation criteria for a "mosquito-free village", providing a replicable model for promotion in hilly and mountainous rural areas.

ObjectiveTo investigate the effect of curcumin on the cycle arrest of human colon cancer HCT116 cells and decipher the possible molecular mechanism. MethodThe methyl thiazolyl tetrazolium (MTT) method was employed to examine the effects of curcumin (0, 12.5, 25, 50, 75, 100 μmol·L-1) and 5-fluorouracil (5-FU, 600 μmol·L-1) on the proliferation of HCT116 cells at different time points (24, 48, 72 h). Flow cytometry was employed to examine the cycle of HCT116 cells treated with curcumin (0, 25, 50, 75 μmol·L-1) and 5-FU. Western blot was employed to determine the expression of proteins in the Janus kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) /cyclin-dependent kinase inhibitor 1A (p21) pathway in HCT116 cells. The binding of STAT1 to p21 promoter region was detected by chromatin immunoprecipitation (ChIP). Small interfering RNA (siRNA) was employed to measure the role of STAT1 in regulating the expression of p21 and that of JAK1 in regulating the activation of STAT1 by Western blot and cellular immunofluorescence, respectively. ResultCompared with the blank group, the HCT-116 cells treated with curcumin and 5-FU showed decreased viability (P<0.05), increased proportions of cells in the G0/G1 phase (P<0.05), decreased proportions of cells in the S phase and G2/M phase (P<0.05), down-regulated protein level of phosphorylated p21 (P<0.05), and up-regulated protein level of p21 (P<0.05). Compared with the curcumin group, the p21 siRNA+ curcumin group presented decreased proportion of cells in G0/G1 phase (P<0.05). Compared with the blank group, curcumin elevated the level of phosphorylated STAT1 (p-STAT1) (P<0.05). Compared with the curcumin group, the curcumin + STAT1 siRNA group showcased up-regulated protein level of p21 in HCT116 cells (P<0.05). The mechanism study showed that curcumin treatment enhanced the enrichment of STAT1 in the p21 promoter region (P<0.05) compared with the blank group. Compared with the blank group, curcumin up-regulated the level of phosphorylated JAK1 (p-JAK1) (P <0.05). Compared with the curcumin group, the curcumin + STAT1 siRNA group demonstrated up-regulated protein levels of p-STAT1 and p21 in HCT116 cells (P<0.05). ConclusionCurcumin may induce the cycle arrest of human colon cancer HCT116 cells by activating the JAK1/STAT1/p21 signaling pathway.

OBJECTIVE:
To testify the spatial relationship between the subscapularis muscle splitting window and the axillary nerve in modified arthroscopic Latarjet procedure, which could provide anatomical basis for the modification of the subscapularis muscle splitting.
METHODS:
A total of 29 adult cadaveric shoulder specimens were dissected layer by layer, and the axillary nerve was finally confirmed to walk on the front surface of the subscapularis muscle. Keeping the shoulder joint in a neutral position, the Kirschner wire was passed through the subscapularis muscle from back to front at the 4 : 00 position of the right glenoid circle (7 : 00 position of the left glenoid circle), and the anterior exit point (point A, the point of splitting subscapularis muscle during Latarjet procedure) was recorded. The vertical and horizontal distances between point A and the axillary nerve were measured respectively.
RESULTS:
In the neutral position of the shoulder joint, the distance between the point A and the axillary nerve was 27.37 (19.80, 34.55) mm in the horizontal plane and 16.67 (12.85, 20.35) mm in the vertical plane.
CONCLUSION
In the neutral position of the shoulder joint, the possibility of axillary nerve injury will be relatively reduced when radiofrequency is taken from the 4 : 00 position of the right glenoid (7 : 00 position of the left glenoid circle), passing through the subscapularis muscle posteriorly and anteriorly and splitting outward.

Objective:To compare the efficacies of robot-assisted unilateral and manual unilateral/bilateral puncture kyphoplasty (PKP) for the treatment of osteoporotic thoracolumbar fracture (OTLF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 64 OTLF patients admitted to First Affiliated Hospital of Kunming Medical University from April 2021 to May 2022. The patients included 28 males and 36 females, aged 57-88 years [(74.5±5.6)years]. Fracture segments were 12 patients from T 1-T 9, 32 from T 10-L 2, and 20 from L 3-L 5. All the patients were treated with PKP. Among them, 25 patients underwent manual unilateral puncture (manual unilateral group), 18 patients underwent manual bilateral puncture (manual bilateral group), and 21 patients underwent robot-assisted unilateral puncture (robot-assisted unilateral group). The operation time, channel establishment time, intraoperative blood loss, intraoperative fluoroscopy times, bone cement injection volume, and bone cement spatial distribution score were compared among the three groups. The visual analogue score (VAS), Oswestry disability index (ODI) and Cobb angle of kyphosis were compared among the three groups before operation, at 3 days and 3 months after operation, and at the last follow-up. The incidence of complications was compared. Results:All the patients were followed up for 6-10 months [(7.0±0.9)months]. The operation time of the manual unilateral group was (30.2±6.1)minutes, which was shorter than (37.9±8.9)minutes of the robot-assisted unilateral group and (49.0±10.2)minutes of the manual bilateral group; the operation time of the robot-assisted unilateral group was markedly shorter than that of the manual bilateral group (all P<0.05). The channel establishment time of the robot-assisted unilateral group was (4.7±1.4)minutes, which was markedly shorter than (10.4±4.4)minutes of the manual unilateral group and (21.7±6.2)minutes of the manual bilateral group (all P<0.05). The intraoperative blood loss of the robot-assisted unilateral group was (23.8±7.2)ml, which was less than (34.3±7.7)ml of the manual unilateral group and (55.9±18.7)ml of the manual bilateral group (all P<0.05). The number of intraoperative fluoroscopy of the robot-assisted unilateral group was (12.1±2.5)times, which was markedly less than (21.2±5.9)times of the manual unilateral group and (39.6±9.5)times of the manual bilateral group (all P<0.05). The channel establishment time, intraoperative blood loss and intraoperative fluoroscopy times of the manual unilateral group were markedly shorter or less than those of the manual bilateral group (all P<0.05). The bone cement injection volume and bone cement distribution score of the robot-assisted unilateral group were (4.7±1.3)ml and (7.9±1.2)points, which were not statistically different from (5.7±1.3)ml and (8.7±1.1)points of the manual bilateral group (all P>0.05), but were markedly higher than (3.0±1.3)ml and (5.1±1.8)points of the manual unilateral group (all P<0.05). There were no significant differences in VAS, ODI and Cobb angle among the three groups at 3 days, 3 months after operation and at the last follow-up (all P>0.05), but which were all lower than those before surgery (all P<0.05). There were no significant differences in VAS, ODI and Cobb angle among three groups before operation, at 3 days, 3 months after surgery and at the last follow-up (all P>0.05). The complication rate was 4.8% (1/21) of the robot-assisted unilateral group, 32.0% (8/25) of the manual unilateral group, and 33.3% (6/18) of the manual bilateral group, with no significant difference between the manual unilateral group and the manual bilateral group ( P>0.05), but both of which was markedly higher than that of the robot-assisted unilateral group ( P<0.05). Conclusion:Robot-assisted unilateral puncture and manual unilateral/bilateral puncture PKP can both achieve satisfactory results for the treatment of OTLF, but robot-assisted unilateral puncture has shorter channel establishment time, less intraoperative blood loss and intraoperative fluoroscopy times, and lower complication rate.
