OBJECTIVE:
To explore the effectiveness and feasibility of two osteotomy guides in medial open wedge high tibial osteotomy (MOWHTO).
METHODS:
Clinical data of 103 patients who underwent routine MOWHTO surgery between January 2020 and December 2022 were collected for retrospective analysis. The patients were divided into two groups based on the method of osteotomy guide plate. The control group of 51 patients received traditional osteotomy guide plate technique, including 17 males and 34 females, aged from 48 to 68 years old with an average of(57.93±4.82) years old, with a disease duration ranged from 1 to 8 years with an average of (4.89±1.49) years. The observation group of 52 patients received personalized osteotomy guide plate technique, including 23 males and 29 females, aged from 48 to 69 with an average of (58.22±5.10) years, with a disease duration ranged from 1 to 9 years with an average of(5.10±1.55) years. The perioperative indicators, complications, and knee joint recovery rate were statistically analyzed for both groups, as well as the preoperative and postoperative coagulation function, fibrinogen (FIB), D-dimer (D-D), gait parameters (step frequency, step length, step speed), biomechanical indicators, weight bearing line (WBL), medial proximal tibial angle (MPTA), joint line conergence angle (JLCA), and anterior cruciate ligament (ACL) function (body width, tibial anterior displacement).
RESULTS:
All patients were followed up for 6 months. The intraoperative blood loss, operation time, and number of fluoroscopic views in the observation group were (358.58±93.76) ml, (84.42±8.17) min, and (2.00±0.44) times, respectively, which were all less than those in the control group (465.55±105.38) ml, (96.53±10.51) min, and (6.31±0.58) times (P<0.05). Three days after surgery, the FIB and D-D levels in the observation group were (4.21±0.48) g·L-1 and (204.47±35.59) μg·L-1, respectively, which were both lower than those in the control group (5.56±0.57) g·L-1 and (311.12±42.23) μg·L-1 (P<0.05). Three months after surgery, the step frequency, step length, and step speed in the observation group were (1.89±0.23) steps·s-1, (0.57±0.15) m, and (0.99±0.11) m·s-1, respectively, which were all higher than those in the control group (1.80±0.18) steps·s-1, (0.50±0.14) m, and (0.95±0.09) m·s-1 (P<0.05). Three months after surgery, the WBL and MPTA in the observation group were (45.53±4.41)% and (87.03±8.15)°, respectively, which were both higher than those in the control group (38.38±4.36)% and (83.68±8.50)°, and the JLCA was (2.36±0.24)°, which was lower than that in the control group (2.61±0.33)° (P<0.05). The ACL body width during internal fixation removal was (5.60±0.51) mm, which was greater than that in the control group (5.08±0.56) mm, and the tibial migration was (5.70±0.42) mm, which was less than that in the control group (6.33±0.48) mm (P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Six months after surgery, there was no significant difference in the recovery rate of knee joint between the two groups (P>0.05).
CONCLUSION
The application of personalized osteotomy guide technique in MOWHTO can help improve knee biomechanics and ACL function, and has less effect on coagulation function and no increase in complications.

Objective:To evaluate the efficacy and safety of mosapride citrate dispersible tablet (MP) combined with Shugan Jieyu capsule (SGJY) in the treatment of functional dyspepsia (FD).Methods:From April 2018 to January 2019, FD patients from 10 hospitals including Renji Hospital, Shanghai Jiaotong University School of Medicine, Luohe Hospital of Traditional Chinese Medicine, the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine, Handan Hospital of Traditional Chinese Medicine and Nanshi Hospital of Nanyang were selected for a randomized, double-blind, placebo-controlled trial. The patient health questionnaire-9 (PHQ-9) and generalized anxiety disorder-7 (GAD-7) were used to assess depression and anxiety in FD patients, respectively. According to the random number table method, 200 FD patients who met the inclusion criteria were randomly divided into SGJY+ MP group and placebo+ MP group, with 100 patients in each group, and all the patients were given oral MP. The patients of the SGJY+ MP group and the placebo+ MP group were given oral SGJY or placebo on the basis of MP, respectively. The patients of both groups were treated continuously for 6 weeks. Total FD symptom scores, PHQ-9 and GAD-7 scores, as well as efficiency and safety were evaluated after treatment. Independent samples t-test and chi-square test were used for statistical analysis. Results:A total of 193 patients were included into the full analysis set with 94 cases in the SGJY+ MP group and 99 cases in the placebo+ MP group. A total of 183 patients completed the 6-week trial, including 89 cases in the SGJY+ MP group and 94 cases in the placebo+ MP group. A total of 198 patients were included in the safety analysis set, including 99 cases in the SGJY+ MP group and 99 cases in the placebo+ MP group.After treatment, the total FD symptom scores of the SGJY+ MP group and the placebo+ MP group were both lower than those of baseline before treatment (3.71±3.06 vs. 11.79±5.18 and 4.17±3.69 vs. 11.19±5.05), and the differences were both statistically significant ( t=-24.87 and -23.27, both P<0.001). The efficacy of the SGJY+ MP group was higher than that of the placebo+ MP group (86.5%, 77/89 vs. 74.5%, 70/94), and the difference was statistically significant ( χ2=4.69, P=0.030). The efficacy of patients with moderate-to-severe anxiety and depression in the SGJY+ MP group was both higher than that of patients in the placebo+ MP group (10/10 vs. 3/7, 85.0%, 17/20 vs. 8/14), and the differences were statistically significant ( χ2=5.66 and 5.33, P=0.017 and 0.010). The efficacy of patients with postprandial distress syndrome (PDS) subtype in the SGJY+ MP group was higher than that of patients in the placebo+ MP group (93.0%, 53/57 vs. 76.5%, 39/51), and the difference was statistically significant (χ 2=5.82, P=0.016). The PHQ-9 scores of patients with depression in both SGJY+ MP and placebo+ MP groups were lower than those at baseline before treatment (3.63±2.76 vs. 7.87±2.24 and 3.35±2.51 vs. 7.63±2.25), and the differences were statistically significant ( t=-14.88 and -15.87, both P<0.001). There was no significant difference in proportion of depressed patients with a ≥50% reduction in PHQ-9 scores from baseline value between the SGJY+ MP group and the placebo+ MP group (60.2%, 50/83 vs. 62.8%, 54/86; χ2=0.05, P=0.825). The GAD-7 scores of anxious patients both the SGJY+ MP group and the placebo+ MP group were lower than the baseline value before treatment (3.27±2.57 vs. 7.09±2.08 and 3.86±2.49 vs. 6.84±1.66), and the differences were statistically significant ( t=-13.30 and -11.47, both P<0.001). The proportion of anxious patients with a ≥50% reduction in GAD-7 scores from baseline in the SGJY+ MP group was higher than that of the placebo+ MP group (54.4%, 43/79 vs. 36.5%, 27/74), and the difference was statistically significant ( χ2=4.53, P=0.033). There were no serious adverse events in both the SGJY+ MP group and the placebo+ MP group during the treatment. There were no significant differences in the incidence of adverse events and adverse reactions during the treatment between the SGJY+ MP group and the placebo+ MP group (7.1%, 7/99 vs. 5.1%, 5/99, and 3.0%, 3/99 vs. 3.0%, 3/99, respectively; both P>0.05). Conclusion:SGTY can safely and effectively improve the efficacy of the prokinetic drugs in the treatment of FD symptoms, especially in FD patients with PDS subtype or with moderate-to-severe anxiety and with depression.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

This study aims to examine the effect of superfine powder and aqueous extract of Polygonati Rhizomaon on natural perimenopausal syndrome in rats and explore the underlying mechanism. To be specific, a total of 60 female SD rats(14-15 months old) with estrous cycle disorder were screened by the vaginal smear and randomized into model control group, β-estradiol 3-benzoate group(0.1 mg·kg~(-1)), superfine powder of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)) and aqueous extract of Polygonati Rhizoma group(0.25, 0.5 g·kg~(-1)), and another 10 female SD rats(14-15 months old) were selected as the youth control group. The administration lasted 6 weeks. Then the perimenopausal syndrome-related indexes such as body temperature, microcirculatory blood flow of face and ear, vertigo period, salivary secretion, grip force, and bone strength were determined and open field test was conducted. The immune system-related indexes such as the wet weight and index of thymus and spleen, percentage of T lymphocytes and subgroups in peripheral blood, and hematological indexes were measured. In addition, the ovary-related indexes such as estrous cycle, the wet weight and index of uterus and ovary, ovarian tissue morphology, and cell apoptosis were determined. Moreover, hypothalamus-pituitary-ovary axis(HPO)-related indexes such as serum sex hormone levels, cytochrome P450 family 11 subfamily A member 1(CYP11A1), cytochrome P450 family 19 subfamily A member 1(CYP19A1), and cytochrome P450 family 17 subfamily A member 1(P450 17A1) in ovarian tissue were measured. The results showed that the superfine powder and aqueous extract of Polygonati Rhizoma significantly decreased body temperature(anal, facial and dorsal temperature), microcirculatory blood flow in the ear, and vertigo period, increased salivary secretion, grip force, bone strength, total distance and total speed in the open field test, wet weight and index of thymus and spleen, lymphocyte ratio, CD3~+ level, and CD4~+/CD8~+ ratio, reduced neutrophil number and ratio, estrous cycle disorder ratio, and number of ovarian apoptotic cells, raised wet weight and index of uterus, wet weight of ovary, levels of inhibin B(INHB), estradiol(E_2), anti-müllerian hormone(AMH), and ovarian CYP11A1 and CYP19A1, decreased follicle-stimulating hormone(FSH) and luteinizing hormone(LH) content, and improved ovarian tissue morphology. It is suggested that the superfine powder and aqueous extract of Polygonati Rhizoma can improve the symptoms associated with natural perimenopausal syndrome in rats and enhance ovarian function and immune function. The mechanism is that they regulate HPO axis function by increasing estrogen synthesis.
