Objective To investigate the effects of comprehensive pelvic floor rehabilitation program on pelvic floor muscle strength, female sexual function index (FSFI) score and sexual satisfaction scale for women (SSS-W) score in patients with perimenopausal female sexual dysfunction. Methods The clinical data of 120 patients with perimenopausal female sexual dysfunction were retrospectively analyzed, and all the patients were treated with estrogen and progesterone replacement therapy. Among the patients, 80 patients were treated with Kegel training program (control group), and 80 patients were treated with Kegel training program combined with comprehensive pelvic floor rehabilitation program (treatment group). The pelvic floor muscle strength, FSFI score, SSS-W score, incidence of algopareunia and sexual life frequency were compared between 2 groups. Results The pelvic floor muscle strength after treatment in treatment group was significantly better than that in control group. The Ⅲ,ⅣandⅤgrade of pelvic floor muscle strength in treatment group was in 5, 42 and 33 cases, and that in control group was in 21, 47 and 12 cases, and there was statistical difference (P<0.05). The FSFI scores and SSS-W scores after treatment in treatment group were significantly higher than those in control group:(32.24 ± 3.70) scores vs. (28.51 ± 2.95) scores and (139.80 ± 16.17) scores vs. (122.33 ± 13.75) scores, and there were statistical differences (P<0.05). The incidence of algopareunia after treatment in treatment group was significantly lower than that in control group:10.00%(8/80) vs. 55.00%(44/80), and there was statistical difference (P<0.05). The sexual life frequency after treatment in treatment group was significantly better than that in control group, the 0, 1, 2 and≥3 times/month of sexual life frequency in treatment group was in 0, 8, 20 and 52 cases, and that in control group was in 5, 34, 24 and 17 cases, and there was statistical difference (P<0.05). Conclusions Comprehensive pelvic floor rehabilitation program in patients with perimenopausal female sexual dysfunction can efficiently promote the recovery process of pelvic floor muscle strength, improve FSFI score and SSS-W score, and increase the degree of sexual satisfaction.

Objective To explore the effects of different doses of topiramate (TPM) on the expression of nerve cell adhesion molecule (NCAM) and growth-associated protein 43 (GAP- 43) mRNA in hippocampus of rats with epilepsy. MethodsForty-eight rats were randomly divided into normal control group, kainic acid (KA) group, 10 mg/kg TPM group, 40 mg/kg TPM group, 100 mg/kg TPM group and 400 mg/kg TPM group (n=8). The models of rats with epilepsy treated by different doses of TPM were established. The behavior of rats was observed, and the expression of NCAM and GAP- 43 mRNA in hippocampus of rats was determined by Real-time PCR. Results The expression of NCAM and GAP- 43 mRNA in KA group was significantly higher than that in normal control group (P<0.01), while there was no significant difference between 10 and 40 mg/kg TPM groups and KA group, that in 100 and 400 mg/kg TPM groups was significantly lower than that in KA group (P<0.01), and that in 400 mg/kg TPM group was significantly lower than that in 100 mg/kg TPM group (P<0.01). Conclusion KA can up-regulate the expression of NCAM and GAP- 43 mRNA in hippocampus of rats with epilepsy. Higher dose of TPM can inhibit the expression of NCAM and GAP- 43 mRNA, and the inhibitory effect is related with the dose of TPM.

BACKGROUND:Our previous studies confirmed that NGF-PEG-PLGA-NPs has good sustained release effect and biological activity in vitro, and can induce the differentiation of PC12 cel s into neuron-like cel s.
OBJECTIVE:To investigate the feasibility of neuronal differentiation of neural stem cel s from septal area of fetal brain induced by NGF-PEG-PLGA-NPs and its influence on PI3K/Akt signaling pathway.
METHODS:According to optimization prescription, NGF-PEG-PLGA-NPs were prepared by multiple emulsion solvent diffusion method. Neural stem cel s were induced to neuronal differentiation in six groups, including control group, NGF group, NGF-PEG-PLGA-NPs group, LY294002 group, LY294002+NGF group and LY294002+NGF-PEG-PLGA-NPs group. Neurons were identified by immunofluorescence, while phosphorylation levels of Akt in PI3K/Akt signaling pathway were detected by western blotting.
RESULTS AND CONCLUSION:The proportions ofβ-Tubulin III-positive neurons in control group, NGF group, NGF-PEG-PLGA-NPs group, LY294002 group, LY294002+NGF group and LY294002+NGF-PEG-PLGA-NPs group were (22.80±2.58)%, (35.80±3.98)%, (35.40±5.77)%, (26.60±3.87)%, (21.20±2.59)%and (25.80±7.22)%, respectively. There were no statistical differences in neuronal differentiation between NGF group and NGF-PEG-PLGA-NPs group (P>0.05), but the ratios of neural differentiation in the two groups were both higher than that in the other four groups (P<0.05). Western blotting results revealed that there were no statistical differences in Akt phosphorylation levels between NGF group and NGF-PEG-PLGA-NPs group (P>0.05), but the phosphorylation levels of Akt were both higher than other four groups (P<0.05). There were also no significant differences between LY294002+NGF and LY294002+NGF-PEG-PLGA-NPs groups and control group (P>0.05), but the phosphorylation levels of Akt were higher than LY294002 group (P<0.05). Results suggest that NGF-PEG-PLGA-NPs promoted neural differentiation of neural stem cel s. The role might be related to increasing phosphorylation levels of Akt in PI3K/Akt signaling pathway.

Objective:To investigate the predictive value of 18F-fluorodeoxyglucose (FDG) PET/CT metabolic parameters for occult lymph node metastasis (OLM) in non-small cell lung cancer (NSCLC). Methods:A total of 183 patients (72 males, 111 females; age (61.5±8.4) years) who underwent 18F-FDG PET/CT and preoperatively diagnosed with clinical N0 stage (cN0) in Third Affiliated Hospital of Soochow University from January 2013 to December 2018 were retrospectively enrolled. All patients underwent anatomical pulmonary resection with systematic lymph node dissections within 3 weeks after 18F-FDG PET/CT examinations. According to the presence or absence of lymph node metastasis, patients were divided into OLM positive (OLM+ ) group and OLM negative (OLM-) group. Parameters of primary lesions, such as the maximum diameter (D max), tumor sites, morphological features, maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), metabolic total volume (MTV), total lesion glycolysis (TLG), tumor SUV max to liver SUV mean (TLR max), tumor TLG to liver SUV mean (TLR TLG) were analyzed. Mann-Whitney U test and χ2 test were used to compare the parameters between groups. Multivariable logistic regression was used to analyze the independent risk factors for OLM. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of different parameters. Results:Among 183 patients, 25 (13.7%, 25/183) of them were diagnosed as OLM. In OLM+ group, 46 lymph nodes were pathologically positive for metastasis, including 15 N1 disease and 31 N2 disease. D max (2.9(2.3, 3.7) vs 2.3(1.7, 2.8) cm), lobulation ((76.0%(19/25) vs 37.3%(59/158)), SUV max (11.1(7.9, 17.7) vs 4.7(2.3, 9.2)), TLG (41.5(10.2, 91.1) vs 15.6(6.5, 23.8) ml), TLR max (4.7(3.5, 7.6) vs 2.1(0.9, 4.0)) and TLR TLG (18.1(5.0, 44.3) vs 6.1(3.0, 11.4) ml) of the primary lesions in OLM+ group were significantly higher than those in OLM-group ( z values: from -4.709 to -3.247, χ2=13.190, all P<0.05). Multivariable logistic regression analysis showed that TLR max (odds ratio ( OR)=15.145, 95% CI: 3.381-67.830, P<0.001) and D max ( OR=3.220, 95% CI: 1.192-8.701, P=0.021) were independent risk factors for OLM. TLR max yielded the highest area under curve (AUC; AUC=0.794) with the threshold of 3.12, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for predicting OLM were 92.0%(23/25), 63.3%(100/158), 67.2%(123/183), 28.4%(23/81) and 98.0%(100/102), respectively. Conclusions:TLR max of tumor is the independent risk factor for OLM in NSCLC patients. TLR max can sensitively predict OLM preoperatively in patients with NSCLC.

OBJECTIVE To investigate the marketing status， general characteristics， and time trends of rare disease drugs in China. METHODS Based on 121 kinds of rare diseases included in the First Batch of Rare Disease Catalog， the names and marketing approval information of corresponding drugs with indications were obtained from the databases of the Center for Drug Evaluation， National Medical Products Administration and Yaozhi.com， and the relevant characteristic variables were extracted for descriptive statistical analysis. RESULTS As of December 31， 2022， only 32 of 121 rare diseases have therapeutic drugs available for treatment on the market in China， and 79 rare disease drugs have been approved. Among them， 46.84% of the drugs are domestic drugs， 88.61% of the drugs are approved for use in both adults and children； 67.09% are chemicals and 59.49% are injections. According to the ATC classification， Category A （digestive system drugs） is the most， accounting for 20.25%. The number of rare disease drugs on the market each year is the highest in 2021， with an overall upward trend from 2018 to 2021 and a downward trend in 2022. Among rare disease drugs on the market each year， according to the ATC classification， the number of Category L （antineoplastics and immune inhibitors） will be the largest in 2021， being 5. By dosage form， oral medicines were marketed in the largest number in 2022， and injectable medicines in 2021. CONCLUSIONS In recent years， the number of approved rare disease drugs in China has been continuously increasing， but it is still far from meeting the needs of patients， and there is still a lack of domestically approved rare disease drugs. We should further accelerate the research and development of rare disease drugs， and promote the import and replication of rare disease drugs.

OBJECTIVETo observe the effects of's neck acupuncture combined with swallowing rehabilitation on swallowing function and quality of life in patients with post-stroke pseudobulbar palsy.

METHODSOne hundred patients were randomly assigned in to an observation group and a control group, 50 cases in each one. The patients in the control group were treated with basic pharmaceutical treatment, including neurotrophy medication and free radical scavenging medication as well as swallowing rehabilitation; the patients in the observation group, on the basis of those in the control group, were treated with's neck acupuncture at Fengchi (GB 20), Yiming (EX-HN 14), Gongxue (Extra), Lianquan (CV 23), Wai Jinjin Yuye (Extra), Tunyan (Extra), Zhiqiang (Extra), Fayin (Extra), once a day, five times a week for continuous eight weeks. The Repetitive saliva-swallowing test (RSST), standardized swallowing assessment (SSA) and swallow quality-of-life questionnaire (SWAL-QOL) before and after treatment in the two groups were observed; the relationship between disease location and frequency and efficacy of's neck acupuncture was explored in the observation group.

RESULTSAfter treatment, the RSST, SSA and SWAL-QOL were superior to those before treatment (all<0.01), with more significant results in the observation group (all<0.01). The total effective rate was 91.7% (44/48) in the observation group, which was superior to 75.5% (37/49) in the control group (<0.01). The frequency of disease onset was one in 11 patients and 2 and above in 37 patients in the observation group, and the efficacy of one onset of disease was 100.0% (11/11), which was superior to two and above of onset 89.2% (33/37,<0.01). The number of patients with disease location at cortex and subcortex was 21, while that at capsula interna and basal ganglia was 27 in the observation group, the efficacy of two was similar (>0.05).

CONCLUSIONS 's neck acupuncture combined with swallowing rehabilitation could effectively improve dysphagia and quality of life in patients with post-stroke pseudobulbar palsy. No correlation of lesion locations on acupuncture efficacy is observed, while onset frequency is inversely proportional to efficacy.
