Effectiveness of Zhenqi Buxue Oral Liquid Combined with Progesterone for Treatment of Oligomenorrhea and Hypomenorrhea with Qi-Blood and Kidney (Shen) Essence Deficiency: A Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effectiveness and safety of Zhenqi Buxue Oral Liquid (ZQ), progesterone capsules, and their combination in treating oligomenorrhea and hypomenorrhea with qi-blood and Kidney (Shen) essence deficiency.@*METHODS@#This was a prospective, randomized, multi-center controlled trial between June 2022 to December 2022. Ninety-six oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency were randomly assigned to receive ZQ (ZQ group, 29 cases), progesterone capsules (PG group, 32 cases), or the combined Chinese and Western medicine (COM group, 31 cases) at a ratio of 1:1:1. Patients in the ZQ or PG group took daily 10 mL twice a day of ZQ or 200 mg once a day of progesterone capsules for 10 consecutive days on day 15 of the menstrual cycle respectively, and patients in the COM group received the same ZQ combined with progesterone capsules. The treatment course lasted for 3 months and follow-up was performed at 1 and 3 months after the end of treatment. Primary endpoint was the menstrual Traditional Chinese Medicine Syndrome Scale (TCMSS) scores. Secondary endpoints included pictorial blood loss assessment chart (PBAC) scores, clinical efficacy rate, 36-item Short Form Health Survey (SF-36) scores, sex hormones and thickness of endometrium. Adverse events (AEs) were recorded.@*RESULTS@#TCMSS scores after 1- and 3-month treatment in all groups were significantly lower than those at baseline (P<0.05). Only TCMSS scores after 3-month treatment in the ZQ and COM groups continuously decreased compared with those after 1-month treatment in the same group (P<0.01). TCMSS scores after 3-month treatment in the ZQ and COM groups were significantly lower than those in the PG group (P<0.05, P<0.01). Compared with baseline, PBAC scores in the ZQ and COM groups after 3 months of treatment were also significantly higher (both P<0.01). The total effective rates of TCM syndrome of 3-month treatment were significantly improved in all groups compared with that after 1 month of treatment (P<0.05). The total effective rate of the COM group was the highest in the 3rd month of treatment and significantly higher than that of PG group alone (P<0.05). Compared with baseline, only the SF-36 scores of COM group were significantly improved after 3 months of treatment (P<0.05). No serious adverse reactions were observed after treatment.@*CONCLUSIONS@#The combination of ZQ and PG, or ZQ only had better effects on reducing TCMSS scores compared with PG, and COM showed the higher total effective rate compared with monotherapy. Besides, COM could effectively improve menstrual blood loss and quality of life. ZQ combined with PG may be an effective and safe option for oligomenorrhea and hypomenorrhea patients with qi-blood and Shen essence deficiency.

Influential factors of leisure exercise among patients with type 2 diabetes mellitus based on the planned behavior theory / 中华疾病控制杂志

Objective This study applied the theory of planned behavior to investigate the leisure exercise situation among patients with type 2 diabetes mellitus (T2DM) and its influencing factors. Methods The questionnaire was self-designed based on the theory of planned behavior, which had good reliability and validity. Structural equation modeling was used to estimate the determinants of leisure exercise and the potential intermediate effect. Results 774 patients with T2DM were enrolled in this study. 52.6% were over 60 years old. The median amount of leisure exercise was 0.0 thousand-step equivalent with quartile of (0.0, 2.0). Structural equation modeling showed that the effects of attitude (β=0.080) and intention (β=0.277) on leisure exercise were significant. Besides, perceived behavioral control (β=0.180) had an indirect effect on exercise through intention. Conclusions In general, most patients with type 2 diabetes have insufficient amount of exercise. Improving attitude, control and intention to exercise would be one crucial part of exercise health education among patients with T2DM.

Study on musculuskeletal ultrasound features and correlation of knee osteoarthritis / 中国骨伤

OBJECTIVE@#To compare the correlation between musculoskeletal ultrasound features, dysfunction and X-ray findings in patients with knee osteoarthritis, and to analyze the pathological mechanism of soft tissue inflammation in knee osteoarthritis.@*METHODS@#Cross-sectional method was performed in this research (Evidence level: III). The patients with knee osteoarthritis were collected according to the screening criteria from September 2016 to January 2017 in Orthopedic clinic in our hospital. Musculoskeletal ultrasound and X-ray images were obtained and measured, knee function was measured by Lysholm scale. Pearson coefficient, t test and Wilcoxon were applied to analyze the correlation between soft tissue inflammation, knee dysfunction and X-ray features.@*RESULTS@#Total 123 patients with knee osteoarthritis were recruited in this research. Soft tissue inflammation around knee had a high incidence in patients with knee osteoarthritis (infrapatellar fat pad inflammation 81%), and the synovial membrane thickness, joint effusion depth and meniscus bulging were beyond the normal range. Correlation analysis showed that the about Lysholm score and joint effusion depth had negative correlations with "Squat" score(=-0.21, =0.02). and Medial meniscus bulging had negative correlations with "Sustain" score(=-0.26, <0.01) and Lysholm total score (=-0.19, =0.04). Lateral meniscus bulging had a negative correlation with "Unstable" score (=-0.22, =0.02). The X-ray features, and medial joint space narrow had negative correlations with joint effusion depth(=-0.27, <0.01) and synovial membrane thickness(=-0.17, =0.007), and had a positive correlation with medial meniscus bulging. Medial joint space narrow was significantly correlated with patellar ligament inflammation and fat pad inflammation(<0.05). Lateral joint space narrow was significantly correlated with patellar ligament inflammation(=0.02).@*CONCLUSIONS@#Soft tissue inflammation around the knee-a major pathological manifestation of knee osteoarthritis, has significant correlations with knee dysfunction and bony structure lesions, and affects the progression of knee osteoarthritis by damaging knee joint function and promoting the destruction of articular cartilage.

Analysis of the relationship between living habit and cervical instability in adolescent patients with neck pain / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the relationship between living habit and cervical instability in adolescent patients with neck pain.</p><p><b>METHODS</b>Fifty-nine adolescent patients with neck pain(neck pain group) and seventeen healthy teenagers (control group) were recruited and divided into two groups, and clinical information, living habit were collected. In addition, all people were taken lateral, hyperextension and hyperflexion radiography to analyze relationship between living habit and cervical instability.</p><p><b>RESULTS</b>There was no obvious difference in age, height, weight and body mass index between two groups. The neck pain group using cellphone time per day is longer than control group, while control group had more exercise time than neck pain group(<0.01). The incidence of instability in neck pain group was significantly higher than that in control group(<0.01). In hyperflexion, angular displacement(AD) of neck pain group in vertebral body between C₃-C₄, C₄-C₅ and C₅-C₆ was significantly higher than that of control group. In neck pain group, AD of hyperflexion was higher than that of hyperextension on C₄-C₅(<0.01), and AD of hyperextension is higher than that of hyperflexion on C₆-C₇(<0.05). In neck pain group, AD of hyperextension on C₄-C₅ was positively correlated with time of using cellphone every day(=0.275, =0.035). And AD of hyperflexion was significantly positive correlated with time of using cellphone(=0.577, <0.001), but was negatively correlated with exercise time(=-0.279, =0.032). The AD of hyperflexion on C₅-C₆ was negatively correlated with exercise time every day(=-0.292, =0.025), AD of hyperextension was negatively correlated with time of using computer every day(=-0.262, =0.045).</p><p><b>CONCLUSIONS</b>Adolescent neck pain patients had more time to use cellphone than normal teens every day, and exercise time is less than healthy teenagers, and occurrence rate of cervical instability is higher on C₃-C₄, C₄-C₅, C₅-C₆ segment. The longer daily exercise time, the smaller C₄-C₅ and C₅-C₆ AD values; the longer cellphone usage every day, the greater C4-C5 AD values.</p>
