Objective To investigate the effects ofTongbicapsule on the knee joint function and the synovial fluid levels of matrix metalloproteinase (MMP)-3,-9 in patients with knee osteoarthritis.Methods A total of 76 patients with knee osteoarthritis were randomly divided into a control group and an observation group according to the random number table, 38 in each group. Patients in the control group were treated with glucosamine hydrochloride capsules, while patients in the observation group were givenTongbicapsule on the basis of the control group. Both groups were treated for 12 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index was used to measure the knee joint function, and enzyme-linked immunosorbent assay was used to determine the synovial fluid levels of MMP-3 and MMP-9.Results The knee joint function in the observation group was significantly improved than that in the control group (94.74%vs. 78.95%;χ2=4.146, P<0.05). The synovial fluid levels of MMP-3 (67.58 ± 22.35 ng/mlvs.93.51 ± 27.84 ng/ml;t=4.477,P<0.01) and MMP-9 (36.24 ± 10.56 ng/mlvs.51.87 ± 12.35 ng/ml;t=5.930,P<0.01) in the observation group patients were significant lower than those in the control group after treatment.ConclusionsTongbicapsule was effective in treating knee joint function in patients with knee osteoarthritis, and its mechanism may be related to its reducing the synovial fluid levels of MMP-3 and MMP-9.

Diabetic foot ulcer is a major complication of diabetes which is the most expensive and the most difficult to deal with and leads to a high rate of non-traumatic amputation.Diabetic foot osteomyelitis results from aggravation of diabetic foot ulcer.Unfortunately,the current therapeutic outcomes of diabetic foot osteomyelitis are still unsatisfactory because of its difficult diagnosis and special treatment protocols which are entirely different from those for conventional soft tissue infections.This paper summarizes the latest advances achieved in diagnosis and treatment of diabetic foot osteomyelitis.

Objective:To investigate the effects of cervical plexus block anesthesia combined with general anesthesia on subtotal thyroidectomy in patients with hyperthyroidism and stress response.Methods:A total of 68 patients with hyperthyroidism who underwent subtotal thyroidectomy in Zhangjiagang City Hospital of Traditional Chinese Medicine, Jiangsu Province, from January 2018 to January 2021 were selected as observation subjects, and were divided into control group and observation group according to the random number table method, both of which were 34 cases. Patients in control group were given general anesthesia, and the observation group was given cervical plexus block anesthesia combined with general anesthesia. The heart rate and mean arterial pressure before anesthesia (T0), immediately before intubation (T1), immediately after intubation (T2), and at the end of surgery (T3), the time of awakening and extubation after surgery, the visual analog score (VAS) of pain at 1, 4, 12, and 24 hours after surgery, stress response of before and 24 hours after surgery, and complications after surgery were compared between the two groups.Results:There was no significant difference in heart rate and mean arterial pressure between the two groups at T0 ( P > 0.05); the heart rate and mean arterial pressure at T1 were lower than those at T0 in the same group ( P < 0.05); the heart rate and mean arterial pressure at T2 and T3 in the control group were higher than those at T0 in the same group ( P < 0.05); the heart rate and mean arterial pressure at T2 and T3 in the observation group did not change significantly compared with those at T0 in the same group ( P > 0.05), but were lower than those in the control group at the same time ( P < 0.05). The awakening time and extubation time of patients in the observation group were shorter than those in the control group ( P < 0.001). The VAS scores of patients in the observation group were lower than those in the control group at 4, 12 and 24 hours after surgery ( P < 0.001). The serum norepinephrine (NE) and cortisol (COR) levels of patients in the two groups at 24 hours after surgery were higher than those before surgery, and the levels in the observation group were lower than those in the control group at the same time ( P < 0.05). The total incidence of postoperative complications in the observation group (8.82%, 3/34) was lower than that in the control group (29.41%, 10/34, χ 2 = 4.66, P = 0.031). Conclusion:Cervical plexus block anesthesia combined with general anesthesia has a good effect on subtotal thyroidectomy in patients with hyperthyroidism, which can speed up the patients' awakening, reduce complication, and has little impact on stress response.

Objective:To compare the clinical effects on new bone formation and foot-ankle function between proximal tibial bone transport and distal tibial bone transport in the treatment of massive bone defects after tibial osteomyelitis debridement.Methods:From July 2012 to July 2017, 42 patients with chronic tibial osteomyelitis received bone transport surgery at Department of Orthopaedics, Nanfang Hospital.According to the Cierny-Mader classification for chronic osteomyelitis, all of them belonged to diffusive tibial osteomyelitis (type IV).Of them, 32 were treated by proximal tibial bone transport after tibial osteomyelitis debridement.In the proximal group, there were 27 males and 5 females, aged from 17 to 65 years and involving 20 left and 12 right sides. The other 10 cases received distal tibial bone transport. In the distal group, all of them were male, aged from 25 to 63 years and involving 6 left and 4 right sides. The 2 groups were compared in terms of external fixation index (EFI) and American Orthopaedic Foot & Ankle Society(AOFAS) Ankle and Hindfoot Scale.Results:There were no significant differences between the 2 groups in the preoperative general data such as gender, age or osteomyelitis site, indicating the 2 groups were comparable ( P>0.05). Both groups obtained complete follow-up. The proximal group was followed up for 590.1 d ± 287.3 d and the distal group for 615.6 d ± 130.6 d, showing no significant difference between groups ( P>0.05). In the proximal group 2 cases developed talipes equinovalgus after bone transport while in the distal group 3 cases did, and surgical intervention was needed for them. Surgical intervention was also carried out for16 cases of non-union at the docking site in the proximal group and for 2 ones in the distal group. The EFI was 76.2 d/cm±50.0 d/cm for the proximal group and 84.3 d/cm ± 59.9 d/cm for the distal group, showing no significant difference between groups ( P>0.05). The AOFAS scores were 81.4±10.1 for the proximal group and 60.0±5.9 for the distal group, showing a significant difference ( P<0.05). Conclusion:In the treatment of massive bone defects after tibial osteomyelitis debridement, no significant difference has been observed in the effect on bone formation between proximal tibial bone transport and distal tibial bone transport, but the former transport may have a less adverse effect on foot-ankle function.

Objective To analyze the influence of patients with multiple cerebral infarction complicated with vascular Parkinsonism (VaP) on cognitive function, and to provide a theoretical basis for the diagnosis and treatment of patients with multiple cerebral infarction complicated with VaP. Methods A toatl of 206 patients with multiple cerebral infarction admitted to Ningde municipal hospital of ningde normal university from January 2020 to January 2022 were selected and divided into VaP group (n=58) and control group (n=148) according to whether they were complicated with VaP. Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of patients. The scale included 8 cognitive domains including attention and concentration, executive function, memory, language, visual structure skills, abstract thinking, calculation and orientation. Pearson was used to analyze the correlation between VaP and MoCA score in patients with multiple cerebral infarction. Age, sex, years of education, white matter disease, diabetes mellitus, coronary heart disease and other vascular risk factors were compared between the two groups. The independent risk factors for VaP in multiple cerebral infarction were analyzed by multiple linear regression. Results MoCA score in VaP group was significantly lower than that in control group (P<0.05). In terms of each item, scores of attention and concentration, memory, language and computation in VaP group were significantly lower than those in control group (P<0.05). Pearson correlation analysis showed that attention and concentration, memory, language and computational scores were correlated with VaP in patients with multiple cerebral infarction (r=-0.475, -0.314 , -0.302 , -0.389, P<0.05). There were statistically significant differences between the two groups in white matter lesions, lesion sites in left hemisphere and frontal lobe, diabetes mellitus and carotid artery plaque (P<0.05).White matter lesions (OR=2.571), diabetes mellitus (OR=2.369) and lesion location in the left hemisphere (OR=2.958) were independent risk factors for VaP in patients with multiple cerebral infarction (P<0.05). Conclusion The risk of VaP in multiple cerebral infarction is high, which is related to the cognitive function of patients. Early intervention such as brain function training should be given to patients with white matter lesions, diabetes and lesions in the left hemisphere. , can significantly improve patients' cognitive function and reduce the occurrence of VaP.

Objective To investigate the efficacy and safety of programmed death receptor-1 (PD-1) inhibitor combined with transarterial chemoembolization (TACE) and anti-angiogenic drug tyrosine kinase inhibitor (TKI) versus TACE combined with TKI in the treatment of advanced hepatocellular carcinoma (HCC) and related influencing factors for prognosis. Methods An analysis was performed for all patients who received TACE+TKI+PD-1 inhibitor and some patients who received TACE+TKI in The First Affiliated Hospital of Air Force Medical University from June 2018 to July 2021. Related clinical data were collected, and propensity score matching (PSM) was used to balance the baseline characteristics between groups. The chi-square test was used for comparison of categorical data between two groups; the Wilcoxon rank-sum test was used for comparison of the number of TACE procedures between two groups; the Kaplan-Meier method was used to analyze overall survival (OS), and univariate and multivariate Cox regression models were used to analyze the influencing factors for prognosis. Results A total of 181 patients with advanced HCC were screened out, among whom 50 patients were treated with TACE+TKI+PD-1 inhibitor; after PSM, 40 patients treated with TACE+TKI+PD-1 inhibitor were enrolled as observation group and 40 patients treated with TACE+TKI were enrolled as control group. At the end of follow-up, the median follow-up time was 28.6 (95% confidence interval [ CI ]: 22.1-35.1) months, and the median OS was 15.9 (95% CI : 7.5-24.2) months in the observation group and 11.2 (95% CI : 5.0-17.5) months in the control group. The Cox regression analysis showed that the application of PD-1 inhibitor (hazard ratio [ HR ]=0.42, 95% CI : 0.23-0.80, P =0.008), the number of TACE procedures ( HR =0.67, 95% CI : 0.46-0.99, P =0.043), Child-Pugh class ( HR =2.40, 95% CI : 1.15-5.00, P =0.019), and vascular invasion ( HR =3.42, 95% CI : 1.11-9.42, P =0.031) were independent influencing factors for prognosis. The incidence rate of grade > 2 adverse events was 40% for both the observation group and the control group, and there was no significant difference between the two groups ( P =0.818). Conclusion Compared with TACE+TKI, TACE+TKI+PD-1 inhibitor can significantly prolong the OS of patients in advanced HCC, with relatively controllable adverse events.
