Parkinson’s disease （PD） is a common chronic neurodegenerative disease with movement disorders as the main clinical manifestation. The nuclear factor-erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway is closely associated with the occurrence and progression of PD. TCM flavonoid monomers （luteolin， rutin， etc.）， alkaloids （camptothecin， sinomenine， and alkaloids extracted from Uncaria rhynchophylla）， terpenes （tanshinone ⅡA， carvacrol， paeoniflorin）， phenols （ellagic acid， rosmarinic acid）， saponins （ginsenoside RK1）， and traditional Chinese medicine compounds （Wuzi yanzong pill and PD formula-2） can resist oxidative stress damage， inhibit inflammatory responses and abnormal aggregation of α-synuclein， and regulate neurotrophic factors by activating the Nrf2/HO-1 signaling pathway， thereby alleviating dopaminergic neuronal damage.

OBJECTIVE: To investigate the effectiveness of Youngswick-Akin osteotomy in the treatment of moderate hallux valgus combined with mild to moderate hallux rigidus. METHODS: The clinical data of 43 patients with moderate hallux valgus combined with mild to moderate hallux rigidus who were admitted between August 2019 and August 2022 and met the selection criteria were retrospectively analyzed. There were 8 males and 35 females. The age ranged from 28 to 77 years, with an average age of 59.0 years. The disease duration ranged from 10 to 35 months, with an average of 20 months. The degree of hallux rigidus included 2 cases of CoughlinⅠ degree, 29 cases of Ⅱ degree, 12 cases of Ⅲ degree. The preoperative hallux valgus angle ranged from 25° to 40°, with an average of 32°. All patients were treated with Youngswick-Akin osteotomy. The first metatarsophalangeal joint space was compared before operation and at 6 months after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were used to evaluate the functional recovery and pain relief of the patients before operation and at 6 and 24 months after operation. According to the severity of hallux rigidus, the patients were divided into mild group (Ⅰ, Ⅱ degree) and moderate group (Ⅲ degree) to compare the prognosis, including the changes of AOFAS score, VAS score, and the first metatarsophalangeal joint space. RESULTS: The operation time was 60-75 minutes (mean, 65 minutes). The intraoperative blood loss was 10-30 mL (mean, 20 mL). Two cases had superficial infection of the incision margin after operation, and healed well after dressing change and antibiotic treatment. The incisions of the other patients healed by first intention, and no medial cutaneous nerve injury of the great toe occurred. All patients were followed up 24-31 months, with an average of 25.8 months. The patient's hallux valgus deformity was corrected without recurrence; no complication such as osteomyelitis and hallux varus occurred. The AOFAS score, VAS score, and the first metatarsophalangeal joint space after operation significantly improved when compared with those before operation, the AOFAS score and VAS score at 24 months after operation further improved when compared with those at 6 months after operation, and the differences were significant ( P<0.05). The change of VAS score in mild group was significantly better than that in moderate group ( P<0.05); but there was no significant difference in the changes of AOFAS score and the first metatarsophalangeal joint space between the two groups ( P>0.05). CONCLUSION Youngswick-Akin osteotomy for moderate valgus deformity with mild to moderate hallux rigidus can achieve good functional recovery, pain relief, and joint space improvement.

Objective To study the efficacy and safety of antiviral therapy in the patients with normal ALT chronic hepatitis B(CHB).Methods The clinical data of the patients with normal ALT CHB visiting in this hospital from December 2019 to December 2023 were collected.The patients were divided into the low vi-ral load group(HBV DNA＜2×106 IU/mL,n=76)and high viral load group(HBV DNA≥2×106 IU/mL,n=10).ETV,TDF and TAF were adopted to conduct the single drug antivirus therapy.The basic informa-tion,demographic characteristics,HBV DNA levels in initial treatment and after 12,24,36,48 weeks of treat-ment,estimated glomerular filtration rate(eGFR)were collected.The rate of complete virological response(CVR)at each time point conducted the statistics for evaluating the effect.The drug safety was evaluated by the eGFR level in 48 weeks of treatment.Results The CVR rates in 12,24,36 weeks of treatment in the low viral load group were 81.6％,94.7％,100.0％and 100.0％respectively,which in the high viral load group were 40.0％,80.0％,80.0％and 80.0％respectively.There was no significant change in eGFR level(109.41±170.57)mL·min-1·1.73 m-2 at 48 weeks of treatment compared with baseline(108.47±110.83)mL·min-1·1.73 m-2(P＞0.05).The ALT and creatinine levels during the treatment process in all the patients were not increased.There was no case of drug withdrawal and drug change due to the drug side effects.Conclusion The overall efficacy and safety of ETV,TDF and TAF monotherapy are good in CHB pa-tients with a family history of cirrhosis or liver cancer and normal ALT.The patients with high viral load at baseline are less likely to achieve CVR in 48 weeks of treatment.

Objective To investigate the effects of denosumab on glucose-lipid metabolism and cardiovascular in patients with postmenopausal osteoporosis(POMP).Methods Patients diagnosed with POMP in Xinjiang Uygur Autonomous Region People's Hospital from 1 January 2017 to 31 August 2022 were selected,and the patients were divided into the desutumomab and atorvastatin calcium group(group A),the desutumomab group(group B),and the control group(group C)according to the drugs used,and the general data and laboratory examinations of the patients in the three groups were collected.General information and laboratory tests were collected from the three groups of patients,and basic information,bone metabolism,glucose metabolism,lipid metabolism,and myocardial injury indexes were compared among the three groups of patients.Results After 1 year of treatment,the alkaline phosphatase level of the three groups of patients decreased significantly compared with that before treatment(P<0.05),and the differences in lactate dehydrogenase(LDH)and fasting blood glucose levels of the three groups of patients after drug treatment were statistically significant(P<0.05),and compared with group C,the reduction of fasting blood glucose in group B was more significant,and the increase in LDH was more significant(P<0.05)after treatment.Comparison of creatine kinase(CK)level in group C and LDH level in group A before and after treatment within the group,the difference was statistically significant(P<0.05).Conclusion The effect of denosumab treatment on glucose metabolism in patients with POMP may be beneficial,and the use of denosumab may be a better choice for patients with diabetes combined with osteoporosis.The present study provides preliminary evidence that denosumab in combination with statin in patients with POMP resulted in lower LDH levels,whereas CK was elevated in patients treated with atorvastatin only,suggesting that denosumab may be more advantageous in regulating glucose metabolism,lipid metabolism,and the prevention of cardiovascular events.

Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.

Objective:To compare the efficacy of modified single-incision and traditional double-incision for flexor hallucis longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 106 patients with Myerson type III chronic Achilles tendon ruptures admitted to Ningbo No.6 Hospital from January 2015 to May 2021, including 54 males and 52 females; aged 48-82 years [(67.2±8.4)years]. Flexor hallucis longus tendon transfer was assigned to 60 patients using modified single-incision (modified single-incision group) and to 46 patients using traditional double-incision (traditional double-incision group). The operation time, intraoperative blood loss as well as American foot and ankle society (AOFAS) ankle-hindfoot score, foot and ankle outcome score (FAOS), visual analogue score (VAS) before operation, at postoperative 12 months and at the last follow-up were compared between the two groups. Time to recover walking and self-care ability, and incidence of complications were compared as well.Results:All patients were followed up for 16-52 months [(37.4±9.5)months]. The operation time and intraoperative blood loss were (51.6±7.4)minutes and (16.6±3.9)ml in modified single-incision group compared to (72.8±7.5)minutes and (32.9±5.2)ml in traditional double-incision group (all P<0.01). There was no significant difference in the AOFAS ankle-hindfoot score, FAOS and VAS between the two groups before operation (all P>0.05). At postoperative 12 months and at the last follow-up, AOFAS ankle-hindfoot score and VAS were not significantly different between the two groups (all P>0.05), but FAOS in modified single-incision group [(112.6±3.0)points, (114.4±3.1)points] was improved significantly compared with traditional double-incision group [(110.8±4.1)points, (112.7±4.3)points] ( P<0.05 or 0.01). At postoperative 12 months and at the last follow-up, the AOFAS ankle-hindfoot score, FAOS and VAS in both groups were improved or decreased significantly compared with those before operation (all P<0.05). All patients recovered their pre-injury daily activities. The time to recover walking and self-care ability were (9.6±2.0)weeks and (12.7±1.7)weeks in modified single-incision group compared to (10.8±1.8)weeks and (13.7±1.9)weeks in traditional double-incision group (all P<0.01). In modified single-incision group, superficial incision infection ( n=1) was found and cured after oral antibiotics. In traditional double-incision group, superficial incision infection ( n=2), deep incision infection ( n=1), deep venous thrombosis ( n=1) and medial plantar nerve injury ( n=1) were found and cured after symptomatic internal medical therapy; claw toe deformity ( n=2) was found and relieved after wearing customized insoles and functional exercise. The incidence of complications was 1.7% (1/60) in modified single-incision group compared to 15.2% (7/46) in traditional double-incision group ( P<0.01). Conclusion:In contrast with traditional double-incision surgery, modified single-incision for flexor longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients has advantages such as shorter operation time, less intraoperative blood loss, better functional recovery, faster postoperative recovery and less complications.

Objective:To investigate the mid-term clinical outcomes of selective column arthrodesis based on the three-column theory in the treatment of malunion of Lisfranc injury.Methods:The 28 patients with malunion of Lisfranc injury were analyzed retrospectively who had been treated by selective column arthrodesis at Department of Orthopedic Surgery, The Second Affiliated Hospital, Zhejiang University School of Medicine from January 2011 to January 2020.They were 18 males and 10 females, with an average age of 37.2 years(from 18 to 65 years). Twelve left and 16 right sides were affected. According to Myerson's three-column classification, one case was medial column injury (type A), 4 ones middle column injury (type B), 7 ones medial plus middle columns injury and 16 ones three-column injury. Medial column arthrodesis was conducted in 7, middle column arthrodesis in 4 and medial plus middle columns arthrodesis in 17. The American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and visual analogue scale (VAS) were compared between preoperation and the last follow-up to evaluate the improvements in foot function and pain. The operation-related complications were recorded.Results:All patients were followed up for an average of 35.6 months (from 18 to 60 months). The AOFAS midfoot score increased from 43.1±4.1 at pre-operation to 84.1± 7.4 at the last follow-up and the VAS score decreased from 5.7±1.3 at pre-operation to 2.0±0.9 at the last follow-up (both P<0.001). The wounds healed in 28 patients, 3 of whom had postoperative wound exudation but responded to dressing change. There were no such complications as injury to the deep peroneal nerve or deep venous thrombosis. The internal fixation was removed in 5 patients at about one year after arthrodesis. Conclusion:Selective column arthrodesis based on the three-column theory can result in satisfactory med-term clinical outcomes in the treatment of malunion of Lisfranc injury.

This study shows the case of a patient with peroneus brevis tendon rupture in ankle fracture. The patient com-plained of swelling, pain and activity limitation in her right ankle caused by sprain. She was diagnosed with ankle fracture, supina-tion-adduction (Lauge-Hansen typing) by medical history, physical examination and imaging. The peroneus brevis tendon was not-ed complete ruptured when suturing the incision after ORIF, which was then repaired by "8" shaped suture. Based on literature re-view, the injury mechanism of the case may be because of overload inversion force toward to lateral inferior from the fracture of fib-ula on the peroneus brevis tendon. Additional attention should be paid to patients who suffered from an supination-adduction ankle fracture for whether peroneus brevis tendon tears before and during surgery.

Objective: To evaluate the effect of zinc ions on human umbilical vein endothelial cells biological functions. Methods: The primary human umbilical vein endothelial cells were cultured with the ECM medium, and cells were divided into 8 groups: the control group(routine culture,n=3), 20 μmol/L zinc group(20 μmol/L zinc chloride solution was added into the cell medium, n=3), 40 μmol/L zinc group(40 μmol/L zinc chloride solution was added into the cell medium, n=3),80 μmol/L zinc group(80 μmol/L zinc chloride solution was added into the cell medium, n=3), 100 μmol/L zinc group(100 μmol/L zinc chloride solution was added into the cell medium, n=3), 200 μmol/L zinc group(200 μmol/L zinc chloride solution was added into the cell medium, n=3),300 μmol/L zinc group(300 μmol/L zinc chloride solution was added into the cell medium, n=3), 500 μmol/L zinc group(500 μmol/L zinc chloride solution was added into the cell medium, n=3). The cell proliferation curve was derived from real time cell analysis (RTCA). The viability value was obtained via CCK-8 reagent, and the migration distance was tested by scratch-wound assay while the adhesion function was detected by RTCA. Results: (1)After 18 hours, RTCA showed that the proliferation cell indexes were 4.5±0.6, 3.7±0.4, 3.6±0.3, 2.5±0.4, and 2.5±0.4 in the 20, 40, 80, 100, and 200 μmol/L zinc groups, as compared with 3.5±0.3 in the control group (all P<0.05). Proliferation cell indexes were 0 in both of the 300 μmol/L and 500 μmol/L zinc groups. (2)After 96 hours, the viability were 1.21±0.05, 1.10±0.03, 0.99±0.05, 0.62±0.02, 0.45±0.04, 0.11±0.01, and 0.12±0.06, respectively in the 20, 40, 80, 100, 200, 300, and 500 μmol/L zinc groups, as compared with 0.75±0.05 in the control group (all P<0.05). (3)After 12 hours, the migration distances were (0.56±0.11),(0.96±0.07),(0.49±0.02), and (0.29±0.01)mm in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with (0.24±0.04)mm in the control group (all P<0.05). (4)After 18 hours, the adhesion cell index were 0.40±0.05, 0.31±0.01, 0.38±0.05, and 0.40±0.03 in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with 0.24±0.04 in the control group (all P>0.05). Conclusions Zinc ions at lower concentration (≤80 μmol/L) can promote proliferation, viability and migration of human umbilical vein endothelial cells, but the adhesion function was not significantly affected by zinc ions. Zinc ions at higher concentration (≥200 μmol/L) can inhibit the cellular function of the human umbilical vein endothelial cells.
