Nasopharyngeal carcinoma is rare in children and adolescents, but the prognosis is relatively good. More and more studies focus on the growth and development, as well as the quality of life of patients after treatment. Certain progress has been made in the research of nasopharyngeal carcinoma in children and adolescents, covering multiple aspects such as etiology, clinical characteristics, treatment regimens and prognosis. The factors causing nasopharyngeal carcinoma include viral infection, genetic susceptibility and environmental factors, etc. The main treatment methods are radiotherapy, chemotherapy, targeted therapy, immunotherapy and surgery. In addition, traditional Chinese medicine has also shown its unique efficacy and potential in the adjuvant therapy of nasopharyngeal carcinoma, providing more treatment options for patients. Further exploration of the factors influencing the occurrence of nasopharyngeal carcinoma in children and adolescents, and analysis of the effects and applications of different treatment methods, can provide new perspectives and references for future research.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

Immunotherapy has become the first-line standard treatment option for driver gene-negative advanced non-small cell lung cancer (NSCLC). But not all patients can benefit from immunotherapy, and can even have serious adverse reactions. It is crucial to identify the predictors of clinical response to immunotherapy. Several studies have shown that elevated baseline C-reactive protein (CRP) or persistent elevation of CRP during the treatment process may indicate a poorer prognosis for patients, and high CRP may be correlated with adverse reactions. Attention to the dynamic changes of CRP during immunotherapy for NSCLC may become an important predictor of prognosis.

Objective:To investigate the association between levator hiatus area, pelvic organ prolapse quantification (POP-Q) examination and prolapse symptoms.Methods:The prospective multicenter study enrolled 996 female patients between January 2017 and January 2019. All enrolled patients underwent a standard clinical interview, POP-Q examination and transperineal ultrasound examination. Volume data of pelvic floor ultrasound examinations were obtained at rest, during contraction and during maximal Valsalva maneuver. The association between levator hiatus area, POP-Q examination and prolapse symptoms was analyzed. The performance of levator hiatus area on maximal Valsalva for assessing significant POP(POP-Q stage≥2) and prolapse symptoms were also evaluated.Results:There were significant differences of levator hiatus area at rest, during contraction and during maximal Valsalva among patients with different POP-Q stages (all P<0.001). Levator hiatus area during maximal Valsalva showed the highest correlation with abdominal dragging sensation ( r=0.277, P<0.001). The area under the ROC curve (AUC) of levator hiatus area during maximal Valsalva for significant POP (POP-Q stage≥2) was significantly higher than that for prolapse symptoms (AUC: 0.77 vs 0.69, P<0.001). Conclusions:Levator hiatus area on transperineal has moderate correlation with POP-Q examination and their association is stronger than the correlation between ultrasound findings and prolapse symptoms.

Objective:To investigate the feasibility of transperineal ultrasound in quantitative assessment of posterior compartment prolapse among Chinese women.Methods:The prospective multicenter study enrolled 485 women between January 2017 and January 2019. All patients underwent a standard clinical interview, pelvic organ prolapse quantification (POP-Q) examination and transperineal ultrasound examination. Volume data of transperineal ultrasound examinations were obtained at rest and in maximal Valsalva maneuver.Results:The higher POP-Q stage of posterior compartment, the lower rectal ampulla position in maximal Valsalva maneuver (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥2, P<0.001), and the greater rectal ampulla hypermobility (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥ 2, P=0.007). The rectal ampulla position at rest and in maximal Valsalva maneuver and rectocele depth were correlated with prolapse symptoms ( r=-0.200, P<0.001; r=-0.252, P<0.001; r=0.086, P=0.045). The corresponding cut-off values of rectal ampulla position in maximal Valsalva in diagnosing posterior compartment prolapse (POP-Q stage ≥1) and clinical significant posterior compartment prolapse (POP-Q stage ≥2) were 7.32 mm below the symphysis pubis and 12 mm below the symphysis pubis, respectively, with the area under the ROC curve as 0.75 and 0.85, respectively. Conclusions:The ultrasonic measurements by transperineal ultrasound is significantly associated with POP-Q examination in posterior compartment, and it is demonstrated as a useful tool in quantitative assessment of the severity of posterior compartment prolapse.

Objective: To observe the clinical efficacy of combined acupuncture and speech rehabilitation in treating postapoplectic aphasia. Methods: Sixty subjects were randomized into two groups. 30 cases in the treatment group were treated by both speech rehabilitation and acupuncture therapy, while 30 cases in the control group were treated by speech rehabilitation only. After 30-day treatments, the clinical efficacy was observed. Results: The total effective rate and speech score were higher in the treatment group than in the control group (P<0.05). Conclusion: Combined acupuncture and speech rehabilitation is quite effective for postapoplectic aphasia.

Purpose To confirm the effects of acupuncture, and Chinese medicines in controlling the withdrawal symptoms from the opium-like drugs. Method 96 heroin-dependent subjects were divided into four groups,which were treated respectively by western medicine (Agroup), acupuncture (B group), Chinese herbs (Cgroup), and acupuncture & Chinese herbs (D group).Before, during and after treatment, the concentration of serum testosterone and prolactin, and immune functions (serum CD3+ 、CD4+ 、CD8+ and CD4+/CD8+ ) were tested.Results After treatment, the concentration of serum testosterone in A and B group were higher than before and during treatment, and in C and D group, during treatment were higher. In the four groups, the concentration of serum prolactin before treatment was the highest. The levels of CD3+、CD4+、 CD8+ and CD4+/CD8+ were lowest before treatment and highest after treatment. Conclusion Acupuncture and Chinese medicines effective in relieving spasm and pain can control the opium-like drug withdrawal symptoms to different degrees, especially acupuncture. However, acupuncture cannot ease the withdrawal symptoms completely. Acupuncture does not strikingly cooperate with the Chinese medicines effective in relieving spasm and pain (including M-receptor antagonists). In detoxification, the Jiaji points are the primary ones and symptom-based points the secondary ones.
