ObjectiveTo explore the epidemic levels and epidemiological characteristics of influenza-like illness (ILI) in Hongkou District of Shanghai, to track the trends in virus mutations, so as to offer a scientific foundation for precisely predicting influenza epidemic trends, providing early alerts, and implementing prompt prevention and control measures. MethodsData on ILI and etiological surveillance from Hongkou District between 2015 and 2024 were collected and statistically analyzed. ResultsThe consultation percentage of ILI (ILI%) in Hongkou District from 2015 to 2024 was 0.58%, and the differences were statistically significant between different years (χ²=19 280.500, P<0.001), with winter and summer being the prevalence peaks. The highest proportion of ILI cases was observed in the 25‒<60 years age group, and the proportion of cases aged ≥60 years showed an increasing trend. The positive rate for influenza viruses was 17.60%, with seasonal influenzaA (H3N2) subtype (49.78%) and influenza A(H1N1) (30.03%) being the predominant strains,and the positive rate was different by years. There was a correlation between ILI% and the positive rate of influenza viruses (r=0.260, P<0.001). The median intensity of influenza activity in 2023‒2024 was 23.09, which was significantly higher than that in 2015‒2019 (H=37.052, P<0.001) and that in 2020‒2022 (H=40.436, P<0.001). ConclusionFrom 2015 to 2022, the ILI% in Hongkou District, Shanghai remained at a relatively low level, but it significantly increased in 2023‒2024, with peaks observed in winter and summer. The predominant influenza virus strains varied and alternated by years. The 2023‒2024 period witnessed an intensified influenza activity. It is necessary to continuously monitor the impact of other respiratory pathogens on influenza epidemic, so as to provide a scientific basis for early warning and prevention and control of influenza.

The Choledochal cyst is an extremely rare congenital anomaly of the bile duct. Early cyst resection and Roux-en-Y hepatojejunostomy are the primary surgical methods for treating choledochal cyst. With the emergence of enhanced recovery after surgery, laparoscopic surgery has effectively reduced the incidence of biliary complications and wound infections, but it still does not meet people's requirements for minimally invasive surgery. Robotic surgery system has the potential to enhance surgical precision and the maneuverability of surgeons due to clear surgical visualization and flexible mechanical arms. The authors review the relevant literatures and conduct a Meta-analysis to evaluate the efficacy of robot-assisted surgery and laparoscopic surgery for choledochal cyst.

Objective:To analyze the acupoint selection law in treating insomnia with warming-needle moxibustion using data mining technology.Methods:The clinical research literature on warming-needle moxibustion in treating insomnia was retrieved from the databases of CNKI, VIP, Wanfang Data, China Medical Journal Full-text Database, SinoMed, PubMed from the establishment of the databases to June 30, 2023. Acupuncture prescriptions were extracted and a database was established. Descriptive analysis was carried out on the intervention measures, the number of moxibustion numbers, the total effective rate, and the relevant information of acupoint selection. Clustering analysis and association rule analysis by using SPSS Statistics 26.0, SPSS Modeler 18.0 were performed on the high-frequency acupoints used in body acupuncture and warming acupuncture, respectively.Results:A total of 67 articles about warming-needle moxibustion for insomnia were included. The main intervention was single warming-needle moxibustion, followed by combined auricular acupuncture. Moxibustion with moxa sticks of 1 to 2 cm in length was often used. The total effective rate was mostly between 92% and 94%. A total of 85 prescriptions were obtained, involving 55 acupoints (569 times in frequency), among which Baihui (DU 20) (55 times), Shenmen (HT 7) (54 times) and Sanyinjiao (SP 6) (45 times) were widely used. The selected acupoints were mainly distributed on the head, face, back and waist, and the affiliated meridians were mainly bladder meridian, Governor Vessel and heart meridian. The specific acupoints were mainly crossing points, followed by back-shu acupoints. Clustering analysis of high-frequency acupoints obtained three effective groups, including "Xinshu (BL 15)- Pishu (BL 20) - Shenshu (BL 23) - Ganshu (BL 18)", etc. Baihui (DU 20) and Shenmen (HT 7) were the most relevant acupoint combinations. A total of 44 acupoints (frequency 272 times) were involved in the selection of warming acupuncture, among which Sanyinjiao (SP 6) (32 times), Xinshu (BL 15) (23 times) and Pishu (BL 20) (23 times) were more frequently used. Clustering analysis of high-frequency acupoints obtained three effective groups, including "Xinshu (BL 15)- Pishu (BL 20) - Shenshu (BL 23) - Ganshu (BL 18)", etc. Pishu (BL 20) and Xinshu (BL 15) were the most relevant acupoint combinations.Conclusions:Warming-needle moxibustion for the treatment of insomnia focuses on the application of acupoints on the bladder meridian on the back and waist, cooperates with the selection of acupoints on the head and face, and attaches importance to the application of intersection points in specific acupoints. The selection of acupoints by warming-needle moxibustion is mainly based on the back-shu acupoints of zang-fu organs, which plays the role of balancing yin and yang, regulating zang-fu organs, tonifying deficiency and tranquilizing mind to help sleep.

Objective:To fabricate the composite scaffolds for bone regeneration with silk fibroin (SF), bacterial cellulose nanofibers (BCNR) and hydroxyapatite (HAp) and evaluate their osteogenic activity.Methods:HAp particles, BCNR and bone morphogenetic protein-2 (BMP2) were added into SF aqueous solution in turn, poured into molds of different sizes after being mixed evenly and processed at -25 ℃ for 24 hours to obtain frozen molds, and the composite scaffolds were frozen-dried by freezing-drying machine. The composite scaffolds with different mass ratios of SF and BCNR were divided into groups A (2∶1), B (4∶1) and C (6∶1), and the inactive composite scaffolds without BMP2 fell into group D. The surface morphology and pore structure of the scaffolds were detected by scanning electron microscopy. The porosity of the scaffolds was measured by mercury intrusion porosimeter. The stress-strain curve was obtained by using the universal material testing machine to compress the scaffolds, with which their compressive strength and Young′s modulus were analyzed. Immortalized mouse embryonic fibroblasts (iMEF) were inoculated on the composite scaffolds of group A, B, C and D. At 4 and 8 days after cell inoculation, the proportion of alive and dead cells in each group was detected by cell survival/death staining; the cell counting kit-8 (CCK-8) was used to detect cell proliferation activity in each group; the positive staining cells were detected in each group by alkaline phosphatase (ALP) staining; the ALP activity was observed in each group with ALP activity detection. A total of 15 female SD rats were selected to establish osteogenesis models with ectopic muscle bag. The composite scaffolds implanted with different SF/BCNR mass ratios and the inactive composite scaffolds without BMP2 fell into group A′ (2∶1), B′ (4∶1), C′ (6∶1) and D′ respectively, and a sham operation group was set at the same time, with 3 rats in each groups. In the sham operation group, the muscle bag and skin were sutured without scaffold implantation after the incision of skin, the blunt separation of the quadriceps muscle, and the formation of muscle bag in the muscle. In the other four groups, the corresponding scaffolds were implanted in the muscle bag and the muscle bag and skin were sutured. X-ray examination was performed at 2 and 4 weeks after operation to observe the osteogenesis in each group. At 4 weeks after operation, the implanted scaffolds and tissue complexes were collected by pathological tissue sectioning, HE staining and Masson staining, and for observing the osteogenesis by in each group. Immunohistochemical staining was also performed on the tissue sections to observe the expression of osteogenic markers type I collagen (COL1) and osteopontin (OPN) in each group.Results:Scanning electron microscopy showed that the lamellar and micropore structures of group B were more regular and uniform than those of groups A and C. The porosity rate analysis showed that the porosity rates of groups B and C were (89.752±1.866)% and (84.257±1.013)% respectively, higher than that of group A [(81.171±1.268)%] ( P<0.05 or 0.01), with the porosity rate of group C lower than that of group B ( P<0.01). The mechanical property test showed that the compressive strengths of groups B and C were (0.373±0.009)MPa and (0.403±0.017)MPa respectively, higher than that of group A [(0.044±0.003)MPa] ( P<0.01), and the Young′s moduli of groups B and C were (7.413±0.094)MPa and (9.515±0.615)MPa respectively, higher than that of group A [(1.881±0.036)MPa] ( P<0.01), with the compressive strength and Young′s modulus of group C higher than those of group B ( P<0.05 or 0.01). The cell survival/death staining showed that the number of dead cells of group B was significantly smaller than that of groups A, C and D at 4 days after cell inoculation, and that group B had the most living cells and the fewest dead cells at 8 days after cell inoculation. The results of CCK-8 experiment showed that at 4 days after cell inoculation, the cell proliferation activity of groups A and B was 0.474±0.009 and 0.545±0.018 respectively, higher than 0.394±0.016 of group D ( P<0.01); the cell proliferation activity of group C was 0.419±0.005, with no significant difference from that of group D ( P>0.05), while the cell proliferation activity of groups A and C were both lower than that of group B ( P<0.01). At 8 days after cell inoculation, the cell proliferation activity of group B was 1.290±0.021, higher than 1.047±0.011 of group D ( P<0.01); the cell proliferation activity of group C was 0.794±0.032, lower than that of group D ( P<0.01); the cell proliferation activity of group A was 1.086±0.020, with no significant difference from that of group D ( P>0.05); the cell proliferation activity of groups A and C was lower than that of group B ( P<0.01). At 4 and 8 days after cell inoculation, ALP staining showed that more positive cells were found in groups A, B and C when compared with group D, and more positive cells were found in group B than in groups A and C. At 4 days after cell inoculation, the ALP activity detection showed that the ALP activity of groups A, B and C was 1.399±0.071, 1.934±0.011 and 1.565±0.034 respectively, higher than 0.082±0.003 of group D ( P<0.01), while the ALP activity of groups A and C was lower than that of group B ( P<0.01). At 8 days after cell inoculation, the cell activity of groups A, B and C was 2.602±0.055, 3.216±0.092 and 2.145±0.170 respectively, higher than 0.101±0.001 of group D ( P<0.01), while the ALP activity of groups A and C was lower than that of group B ( P<0.01). X-ray examination results showed that at 2 weeks after operation, no obvious osteogenesis was observed in the sham operation group, group D′, A′ and C′, while it was observed in group B′. At 4 weeks after operation, obvious osteogenesis was observed in group A′, B′ and C′, with significantly more osteogenesis in group B′ than in the other two groups, while there was no obvious osteogenesis in the sham operation group and group D′. At 4 weeks after operation, the HE staining and Masson staining showed that a large number of uniformly distributed new bone tissue was formed in group B′, while only a small amount of new bone tissue was found locally in groups A′ and C′, and only part of new tissue was found to grow in group D′ with no obvious new bone tissue observed. The maturity of new bone tissue formed in group B′ was higher than that in group A′ and C′. Immunohistochemical staining showed more COL1 and OPN positive staining in group B′ when compared with groups A′ and C′. The expression intensity analysis of COL1 and OPN showed that in groups A′, B′ and C′, the expression intensity of COL1 was 2.822±0.384, 22.810±2.435 and 12.480±0.912 respectively and the expression intensity of OPN was 1.545±0.081, 5.374±0.121 and 2.246±0.116 respectively, with higher expression intensity of COL1 and OPN in groups B′ and C′ than that in group A′ ( P<0.01) and lower expression intensity of COL1 and OPN in group C′ than that in B′ group ( P<0.01). Conclusions:The composite scaffold for bone regeneration is successfully fabricated with SF, BCNR and HAp. The composite scaffold with a mass ratio of SF to BCNR of 4∶1 has uniform pore structure, high porosity, good mechanical properties and biocompatibility, excellent pro-osteogenic properties in vitro, as well as excellent osteo-inductivity and osteo-conductivity.

In this study, a new ileal orthotopic bladder (Urumqi Bladder) modified by our center based on the ileal "W" type orthotopic bladder and Studer bladder was used on 8 patients with invasive bladder cancer. All of patients were male and aged between 54 and 66 years. The history of disease ranged from 1 month to 3 years, including 5 patients with initial onset, 3 patients with ≥2 TURBT history. 6 patients had multiple tumors, tumor size from 0.5 cm to 2.5cm. There were 2 patients with single tumor. Preoperative PET-CT examination showed no distant metastasis and pelvic lymph node enlargement, no urinary tract hydronephrosis, and cystoscopy showed no suspected tumor in the urethra. Preoperative pathological results: high-grade invasive urothelial carcinoma was found in 6 cases and muscular invasive urothelial carcinoma in 2 cases. In 8 patients, 50cm ileum was taken from 15cm away from ileocecum after radical cystectomy, which was crimped clockwise inward from the right end into a nearly circular shape, with 10cm left at the left end. The remaining 40cm ileum was formed into 3 sections of about 13cm each, which were decanted to form a storage capsule. The last 10cm intestinal tube was crossed from the front of sigmoid colon. The end of intestine was anastomosed with the left ureter. The right ureter was anastomosed with the top of the right intestine pouch, and the urethra was anastomosed with the pouch to complete the diversion of urine flow. During 3-12 months of postoperative follow-up, 4 patients had short-term mild urinary incontinence. All had complete urinary control at 12 months. 1 patient still had mild left ureter reflux 12 months after surgery, and the other 7 patients had no ureter reflux. In this group of 8 patients, postoperative excretory cystography showed satisfactory effect of bladder voiding, residual, and bladder capacity. Follow-up review of chest CT, urinary CT and abdominal ultrasound showed no hydronephrosis, and no tumor recurrence or distant metastasis.

Type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) are the most problematic metabolic diseases in the world. NAFLD encompasses a spectrum of severity, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis, increasing the risk of cirrhosis and hepatocellular carcinoma. Importantly, NAFLD is closely linked to obesity and tightly interrelated with insulin resistance and T2DM. T2DM and NAFLD (T2DM-NAFLD) are called as the Xike Rixijing Disease and Tonglaga Indigestion Disease respectively, in Mongolian medicine. Xike Rixijing Disease maybe develop into Tonglaga Indigestion Disease. Forturnately many Mongolian medicines show efficient treatment of T2DM-NAFLD, such as Agriophyllum squarrosum, Haliyasu (dried powder of camel placenta), Digeda-4 (herbs of Lomatogonium carinthiacum, rhizomata of Coptis chinensis, ripe fruits of Gardenia jasminoides, herbs of Dianthus superbus), Guangmingyan Siwei Decoction Powder (Halite, ripe fruits of Terminalia chebula, rhizomata of Zingiber officinale, fruit clusters of Piper longum), Tonglaga-5 (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius), Tegexidegeqi (rhizomata of Inula helenium, ripe fruits of Gardenia jasminoides, rhizomata of Platycodon grandiflorum, rhizomata of Coptis chinensis, heartwood of Caesalpinia sappan), Ligan Shiliu Bawei San (ripe fruits of Punica granatum, barks of Cinnamomum cassia, ripe fruits of Amomum kravanh, fruit clusters of Piper longum, flowers of Carthamus tinctorius, ripe fruits of Amomum tsao-ko, rhizomata of Zingiber officinale), etc. Principles of Mongolian medicine in treating diseases: by balancing “three essences or roots” and “seven elements”, strengthening liver and kidney function, transporting nutrients to enhance physical strength and disease resistance, and combined with drugs for comprehensive conditioning treatment. However, their molecular mechanisms remain unclear. In this review, we prospect that Mongolian medicines might be a promising treatment for T2DM-NAFLD by activating P2X7R/NLRP3/NF-κB inflammatory pathway via lipid-sensitive nuclear receptors (i.e., FXR and LXR).

[Abstract] Objective: To explore the influence of miR-339-5p on the radio-sensitivity of lung cancer A549 cells by regulating the expression of Nudix hydrolase 5 (NUDT5). Methods: X-ray-resistant lung cancer A549 cells (RA549) were induced by treatment with low concentration gradient increment combined with large dose intermittent shock in vitro. The expression level of miR-339-5p in hu‐ man normal lung epithelial cells (BEAS-2B) and lung cancer cell lines (A549, L78, H1299, H460 and RA549 cells) was detected by qP‐ CR. According to the treatment, RA549 cells were divided into NC group, 5Gy group (treatment with 5Gy X-ray), 5Gy+miR-339-5p mimic group, 5Gy+si-NUDT5 group and 5Gy+si-NUDT5+miR-339-5p inhibitor group. CCK-8 assay, Annexin V-FITC/PI double stain‐ ing flow cytometry and WB were used to detect the proliferation, apoptosis and the protein expressions of NUDT5, γ-H2AX and H2AX in each group. The targeting relationship between mir-339-5p and NUDT5 was detected by Dual-luciferase reporter gene system. Results: The expression of miR-339-5p in lung cancer cell lines was significantly lower than that in BEAS-2B cells, with the lowest ex‐pression level in RA549 cells (all P<0.05). NUDT5 was the target gene of miR-339-5p. Compared with the NC group, the prolifera‐ tion activity and NUDT5 expression of RA549 cells in the 5 Gy group were significantly reduced (all P<0.01), and the apoptosis rate was significantly increased (P<0.01). Compared with the 5 Gy group, the proliferation activity of RA549 cells in the 5 Gy+miR-339-5p mimic group was significantly reduced (P<0.05), the apoptosis rate ([12.97±1.48]% vs [5.21±0.62]%, P<0.01) and the expression level of γ-H2AX (P<0.05) were significantly increased; the expression of NUDT5 (t=7.58, P<0.01) and cell proliferation activity (t=6.58, P<0.01) of RA549 cells in the 5 Gy+si-NUDT5 group were significantly reduced, while the apoptosis rate ([11.21±1.06]% vs [5.54±0.44%, P<0.01) and the expression of γ-H2AX (P<0.01) were significantly increased; and the above indicators in 5 Gy+si-NUDT5+miR-339-5p inhibitor group showed insignificant difference from the 5 Gy group. Conclusion: Overexpression of miR-339-5p enhances the radio-sensitivity of X-ray-resistant lung cancer A549 cells by targetedly down-regulating NUDT5 expression.

OBJECTIVE: To explore the pathogenesis of two fetuses from one family affected with Joubert syndrome (JS). METHODS: Whole exome sequencing was employed to screen potential mutations in both fetuses. Suspected mutations were verified by Sanger sequencing. Impact of intronic mutations on DNA transcription was validated by cDNA analysis. RESULTS: Two novel TCTN1 mutations, c.342-8A>G and c.1494+1G>A, were identified in exons 2 and 12, respectively.cDNA analysis confirmed the pathogenic nature of both mutations with interference of normal splicing resulting in production of truncated proteins. CONCLUSION The genetic etiology of the family affected with JS has been identified.Above findings have enriched the mutation spectrum of TCTN1gene and facilitated understanding of the genotype-phenotype correlation of JS.

OBJECTIVE: To investigate the computed tomography findings, clinicopathological features, genetic characteristics and prognosis of in situ adenocarcinoma (AIS) and minimally invasive adenocarcinoma (MIA) of the lung. METHODS: We retrospectively analyzed the data including computed tomography (CT) images, histopathological findings, Ki-67 immunostaining, and genetic mutations in patients with lung adenocarcinoma undergoing surgery at our hospital between 2014 and 2019. RESULTS: Of the total of 480 patients with lung adenocarcinoma we reviewed, 73 (15.2%) had AIS (=28) or MIA (=45) tumors. The age of the patients with MIA was significantly younger than that of patients with AIS ( < 0.02). CT scans identified pure ground-glass nodules in 46.4% of AIS cases and in 44.4% of MIA cases. Multiple GGOs were more common in MIA than in AIS cases ( < 0.05), and bluured tumor margins was less frequent in AIS cases ( < 0.05). No significant difference was found in EGFR mutations between MIA and AIS cases. A Ki-67 labeling index (LI) value ≥2.8% did not differentiate MIA from AIS. The follow-up time in MIA group was significantly shorter than that in AIS group, but no recurrence or death occurred. CONCLUSIONS Despite similar surgical outcomes and favorable survival outcomes, the patients with AIS and MIA show differences in terms of age, CT findings, EGFR mutations and Ki-67 LI.

Objective To explore the relationship between lumbar disc degeneration (LDD) of lumbar spinal stenosis(LSS)and the dural sac cross-sectional area(DSCA)by MRI measurement. Methods 91 patients with central degenerative LSS were randomly selected and 91 age-and sex-matched people without LSS were select-ed as a control group. LDD was classified into five grades by MRI detection according to the method proposed by Pfirrmann and DSCA were measured. Results LDD was not associated with age in LSS. The proportion of severe degenerated disc in lower lumbar levels were higher than that of L2/3 in the two groups;DSCA in severe degenerat-ed disc group was significantly smaller than that in light degenerated group only in L2/3 and L3/4 in LSS. There were no statistical differences in every lumbar level in the control group. Conclusions LDD in L4/5 and L5/S1 of LSS is more severe than that of the normal people. DSCA and LDD are positively correlated in L2/3 and L3/4,but not in L4/5 and L5/S1 for LSS.
