Methods We used Unified Parkinson Disease Rating Scale(UPDRS)part Ⅲ,V,the PD NMS Questionnaire,activities of daily living(ADL)and mini-mental state examination(MMSE)to assess motor and non-motor symptoms in 81 patients with Parkinson disease. Results In PD,a range of NMS occurred across all disease stages.Each PD patient had 7 different NMS on average.The problems of remembering thing,constipation and nocturia ranked top 3 of NMS in patients with PD.There was a significant association of total NMS score with H-Y stage(P<0.01)and UPDRS Ⅲscore(P<0.01).There was a negative correlation between NMS score and ADL score(P

Objective To explore the mechanism of preventive effect of Chinese medicine with Replenishing kidney and invigorating Qi on osteoarthritis. Methods 72 male Long-eared white rabbits aged 4 months were randomly divided into six groups, A group (blank control group), B group (model group), C group (traditional Chinese medicine high-dose prevention group), D group (Chinese herbal medicine with medium-dose prevention group), E group (Chinese herbal medicine with low-dose prevention group), F group (glucose-amino acid hydrochloride capsules prevention group).All the animals apart from A group were established osteoarthritis model by immobilizing knee joint with plaster cast for 6 weeks. In the same time of immobilization, traditional Chinese medicine and glucose-amino acid hydrochloride capsules were given to C, D, E and F group for 4 weeks. Physiological saline was given to B group. After 6 weeks of modeling, synovial fluid was extracted and the changes of TNF-α in it were analyzed by ELISA. Results Articular cartilage degeneration of B group was most obviously compared with C, D, E and F group. There was a significant difference of TNF-α level in comparison of A and B group (P＜0.05), B and C, D, E and F group (P＜0.05), and among C, D and E group. Conclusion Chinese medicine with replenishing kidney and invigorating Qi can prevent osteoarthritis by reducing TNF-α level in synovial fluid, enhancing cartilage cell metabolism, and slowing down cartilage degradation.

Objective To determine whether or not 810 nm low power Ga-Al-As laser treatment can stimulate the regeneration of damaged optic nerves by measuring the expression of growth associated protein 43 ( GAP-43 )and flash-visual evoked potential (F-VEP). Methods Eighty-eight Wistar rats weighing (180-220) g were randomly divided into a laser therapy group with 40 rats,an injury group with 32 rats,and a normal control group with 16 rats.Each group was subdivided into 1st,3rd,6th and 9th week subgroups.A standardized crushing of the optic nerve was applied to make the model.After this,the laser therapy group was treated for 3 minutes daily at 60 mW applied transcutaneously to a 5 mm diameter spot on the injured optic nerve.The injury and normal control groups received the same treatment with no laser output.The expression of GAP-43 was detected by immunohistochemistry and RT-PCR after 1,3,6 and 9 weeks of treatment.F-VEP was measured pre-injury,immediately after injury and 1,3,6 and 9 weeks post injury. Results After the optic nerve was injured,obvious changes in F-VEP were detected,including significantly prolonged latencies of N1,P1 and N2 waves.The latency increased immediately after the optic nerve injured,and then recovered,but after 1 and 3 weeks the latency was still prolonged.There was significant recovery from the 3rd to the 9th week.In the laser therapy group,the peak latencies of the N1,P1 and N2 waves were also prolonged,but the changes were less than those in the injury group.Expression of GAP-43 was hardly detectable in normal retinas and optic nerves.GAP-43 had its highest expression level at 1 week post-injury,and then decreased.At the 1st,3rd and 6th week post-injury,the expression of GAP-43 in the laser therapy group was significantly higher than in the injury group.GAP-43 mRNA content in the retina showed the same tendency as GAP-43 protein. Conclusion A 810 nm low power Ga-Al-As laser can promote neural repair and axonal regeneration after optic nerve injury.

Nonalcoholic steatohepatitis (NASH) is an important pathological stage of nonalcoholic fatty liver disease characterized by hepatocyte fatty degeneration, liver injury, and liver inflammation and can further develop into liver cirrhosis and hepatocellular carcinoma. The NOD-like receptor family, pyrin domain-containing protein 3 (NLRP3) inflammasome is a multi-protein complex in cells and can induce cell apoptosis and expand inflammatory response by activating caspase-1 and releasing mature inflammatory factors such as interleukin-1β and interleukin-18. Recent studies have found that NLRP3 inflammasome may participate in the development and progression of NASH. Therefore, this article summarizes the role of NLRP3 inflammasome in NASH, so as to provide a theoretical basis for future research and treatment.

Liver cancer is a malignant tumor with the characteristics of high morbidity and mortality.However,the routine detection methods for the liver cancer such as imaging tests and pathological detection are with low specificity and sensitivity.And it's also hard to detect the condition of patients dynamically.Cell-free DNA (cfDNA) is the DNA fragment that is away from the extracellular and exists in the blood,which contains genetic information from the organism.The related disease information could be reflected on the cfDNA in patients with liver cancer,indicating that cfDNA has great potential in the screening,diagnosis,treatment and prognosis of liver cancer.The clinical applications of cfDNA can make up for the deficiency of existing detection methods and achieve noninvasive and dynamic monitoring of liver cancer.This article will present a review on the progress of clinical applications of cfDNA in liver cancer.

Objective To investigate the effects of an ar?turmerone derivative(ATD)on the proliferation and apoptosis of A375 human melanoma cells. Methods Both A375 cells and human skin fibroblasts (HSFs) were cultured with different concentrations(5, 10, 20, 40 and 80μmol/L)of ATD, vincristine and ar?turmerone, separately, for 48 hours in vitro. Subsequently, cell counting kit?8 (CCK?8) was used to evaluate cell proliferation, inverted microscopy to observe cell morphology after acridine orange/ethidium bromide (AO/EB) staining, and a colorimetric method to estimate caspase?3 activity. DNA fragmentation assay and flow cytometry were performed to assess cell apoptosis, and flow cytometry was conducted to analyze cell cycle. Results ATD, vincristine and Ar?turmerone all inhibited the proliferation of A375 cells in a dose?dependent manner(ATD:R2=0.99, F=340.96, P<0.05;vincristine:R2=0.99, F=349.19, P<0.05;ar?turmerone:R2=0.89, F=25.41, P<0.05). The fifty percent inhibitory concentra?tions(IC50s)of ATD, vincristine and ar?turmerone against A375 cells were 15.96 ± 0.02μmol/L, 77.00 ± 0.04μmol/L and 356.95 ± 0.01μmol/L respectively. When the drug concentrations were 5 and 10μmol/L, the proliferation of HSFs was inhibited by 8%± 0.06%and 25%± 0.02%respectively by ATD, by 49%± 0.09%and 34%± 0.07%respectively by ar?turmerone, and by 33%± 0.04%and 29%± 0.08%respectively by vincristine, and the proliferation of A375 cells was inhibited by 26%± 0.06%and 39%± 0.02%respectively by ATD, by 6%± 0.09%and 10%± 0.07%respectively by ar?turmerone, and by 8% ± 0.04% and 17% ± 0.08% respectively by vincristine, with the inhibitory effects of the three drugs being significantly different from that of dimethyl sulfoxide(all P<0.05). ATD showed stronger inhibitory effects on the proliferation of A375 cells, but weaker cytotoxic effects on HSFs compared with ar?turmerone and vincristine(all P<0.05). Meanwhile, ATD, vincristine and ar?turmerone all induced the apoptosis of A375 cells(P<0.05), and caspase?3 activity increased with the increase in drug concentrations(ATD:R2=0.98, F=162.30, P<0.05;vincristine:R2=0.96, F=94.39, P<0.05;ar?turmerone:R2=0.95, F=57.35, P<0.05). The effect of ATD on caspase?3 activity was strongest, followed by that of vincristine and ar?turmerone. As flow cytometry showed, all the three drugs induced cell apoptosis to different degrees, and ATD showed a relatively strong effect on cell apoptosis, especially late apoptosis, compared with the other two drugs. In the ATD group, the number of A375 cells in G1 phase gradually increased, while that in G2 phase and S phase significantly decreased with the increase in drug concentrations. Conclusions ATD exhibited proliferation?inhibiting and apoptosis?inducing effects on A375 cells, and the effects were stronger than those of vincristine and ar?turmerone. It is quite possible that ATD affects cell proliferation and differentiation by activating caspase?3 and arresting cell cycle in the G1 phase.

Objective:To investigate the efficacy of fruquintinib in the treatment of advanced colorectal cancer, and to analyze the risk factors for all-cause death of fruquintinib.Methods:The clinical data of 82 patients with advanced colorectal cancer in the First Affiliated Hospital of Bengbu Medical College from December 2020 to April 2022 were retrospectively analyzed. The basic clinical data, efficacy and adverse reactions were recorded. The patients were followed up to October 2022, and all-cause death was recorded. Multivariate Logistic regression was used to analyze the risk factors of all-cause death in patients with advanced colorectal cancer treated with fruquintinib.Results:After treatment, partial remission was found in 9 cases, stable disease in 42 cases, disease progression in 31 cases. The objective remission rate was 10.98% (9/82), and the disease control rate was 62.20% (51/82). The incidence of adverse reactions was 75.61% (62/82), mainly hypertension and hand-foot syndrome. By the end of follow-up, 19 patients died and 63 survived. The incidences of body mass index (BMI)≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L in all-cause death patients were significantly higher than those in survival patients: 36.51% (23/63) vs. 16/19, 39.68% (25/63) vs. 13/19, 44.44% (28/63) vs. 15/19 and 41.27% (26/63) vs. 14/19, and there were statistical differences ( P<0.01 or <0.05); there were no statistical differences in gender composition, age, smoking history, hypertension and postoperative complications between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that BMI≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L were independent risk factors for all-cause death in patients with advanced colorectal cancer treated with fruquintinib ( OR = 9.275, 3.293, 4.687 and 3.985; 95% CI 2.440 to 35.265, 1.106 to 9.806, 1.398 to 15.715 and 1.277 to 12.430; P<0.01 or <0.05). Conclusions:Fruquintinib is effective in the treatment of advanced colorectal cancer. The BMI≥24 kg/m 2, lymph node metastasis, tumor located in the right colon and lactate dehydrogenase >200 U/L are independent risk factors for all-cause death in patients with advanced colorectal cancer treated with fruquintinib.

Objective: To evaluate the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy(Lap-RAMPS) for left-sided pancreatic adenocarcinoma. Methods: Clinical data of total 12 patients underwent Lap-RAMPS for left-sided pancreatic adenocarcinoma at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital from March 2016 to August 2017 were reviewed retrospectively.There were 7 male patients and 5 female patients, with median age of 60.5 years old(47-68 years old). Abdominal enhanced CT, pancreatic MRI, PET-CT were performed on all patients to evaluate the lesion and exclude metastasis.Follow-up were done with out-patient clinic or telephone consultancy until October 2017. Results: All patients underwent pure Lap-RAMPS.The medium operative time was 250 minutes(180-445 minutes), and the blood loss was 150 ml(50-500 ml). The medium first flatus time and diet resumption time were 3.0 days(1-5 days) and 3.5 days(1-7 days) respectively.The medium postoperative hospital stay was 9 days(4-18 days). Morbidity occurred in 8 patients with gastric empty delay(n=1), bleeding(n=1), fluid collection(n=3). There was no mortality.The medium overall number of retrived lymph nodes was 15.6 and the positive rate was 41.7%. The R0 rate was 100%.The medium follow-up was 10 months.One patient was diagnosed as liver metastasis after 8 months and accepted chemotherapy.One patient died after 14 months for tumor recurrence and metastasis.Others survived without tumor recurrence or metasitasis. Conclusion Lap-RAMPS is safe and feasible with accepted oncological outcomes for selected left side pancreatic adenocarcinoma under skilled hands.

Objective:To investigate the prevalence of hyperuricemia (HUA), patients′ awareness of HUA, and related factors among elderly in community.Methods:The health check-up data of 6 897 residents aged over 65 years in Gumei Community of Shanghai were collected from January 2019 to January 2020. There were 1 156 subject with increased serum uric acid levels (HUA group) and 5 741 with normal uric acid levels (non-HUA group). The differences of clinical indicators between HUA group and non-HUA group were analyzed and the risk factors of HUA was determined by multivariate logistic stepwise regression. A questionnaire survey on the knowledge of HUA and the adoption of relevant health behaviors was conducted among HUA patients.Results:The overall prevalence was 16.8% (1 156/6 897) in this population. The prevalence in males was significantly higher than that in females[26.4%(842/3 195) vs. 8.5%(314/3 702), P<0.001); and the prevalence in females increased with age (χ 2=7.56, P=0.023). Body mass index(BMI), waist circumference(WC), total cholesterol(TC), triglyceride(TG), serum creatinine, alanine aminotransferase(ALT) and albumin/urine creatinine ratio(UACR) in the HUA group were significantly higher than those in the non-HUA group, while estimated glomerular filtration rate(eGFR) and high-density lipoprotein(HDL) were lower than those in the non-HUA group (all P<0.01). The prevalence of hypertension, decreased renal function, overweight or obesity, abdominal obesity, fatty liver and renal cyst in HUA group was significantly higher than that in non-HUA group (all P<0.01). High values of TG, low-density lipoprotein(LDL), WC, hypertension and fatty liver were risk factors for HUA( OR=1.14, 1.20, 1.03, 1.43, 2.19; P<0.01); while female gender, eGFR, HDL and glycosylated hemoglobin A1c(HbA1c) were protective factors for HUA( OR=0.32, 0.94, 0.65, 0.78; P<0.01). The questionnaire survey was conducted among 1 090 HUA patients, and the results showed that 73.2% (798 cases) were aware of the disease after the health check-up results released; only 30.9% (337 cases) knew the diagnostic criteria of HUA, 21.1% (230 cases) knew that HUA needed life-long follow-up care, 56.3% (614 cases), 49.2% (536 cases) and 47.9% (522 cases) thought that HUA should eat less seafood, broth and soya bean products, 17.0%(185 cases) were atcohol drinker and the awareness rates of above questions in patients with gout were higher than those in patients without gout ( P<0.05). Conclusion:The study shows that the prevalence of HUA among the elderly in Gumei community of Shanghai is high, and the HUA related knowledge levels and health behavior performance are not ideal, especially for HUA patients without gout, therefore health education should be strengthened for elderly residents in the community.
