OBJECTIVES:
To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication.
METHODS:
Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups.
RESULTS:
After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05).
CONCLUSIONS
The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Objective:To systematically integrate qualitative research on the decision-making experience of fertility preservation in cancer patients of childbearing age, so as to provide evidence-based basis for improving patients' fertility preservation decision-making ability and formulating targeted intervention plans.Methods:Qualitative research on the decision-making experience of fertility preservation in cancer patients of childbearing age was systematically searched on PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI) , Wanfang Database, VIP and China Biology Medicine disc. The search period was from database establishment to December 2, 2022. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Australia Joanna Briggs Institute Evidence-Based Health Care Center. The results were integrated using the Meta-synthesis method.Results:A total of 11 articles were included, 28 results were extracted, summarized into 6 categories, and formed 3 integrated results. The integration results included the challenges and opportunities faced by fertility preservation decision-making, fertility preservation decision-making was influenced by individual, family and social factors, and lack of sufficient decision-making support.Conclusions:Cancer patients of childbearing age lack decision-making support for fertility preservation and face decision-making difficulties. Medical and nursing staff should comprehensively evaluate the fertility needs of cancer patients of childbearing age, pay attention to their cognition and experience, provide professional fertility counseling, and help patients make high-quality decision-making.

OBJECTIVE:
To explore the technique of autogenous bone graft combined with plate fixation in total knee arthroplasty(TKA) with severe proximal medial tibial bone defect.
METHODS:
From March 2012 to October 2018, 21 patients (9 males and 12 females) with severe bone defects in the proximal medial tibia during primary total knee arthroplasty were treated with autogenous structural bone grafting and steel plate fixation, with an age of 61 to 77 years old with an average of (69.6±9.1) years and a course of 64 to 257 months with an average of (73.6±170.7) months. According to Rand classification, there were 13 cases of type Ⅲb and 8 cases of type Ⅳb. Postoperative complications were observed, and knee joint function was evaluated by the Hospital for Special Surgery (HSS) score and SF-36 quality of life score.
RESULTS:
All 21 patients were followed up for 37 to 64 months with an average of (49.5±13.7) months. The incisions of all patients healed smoothly, and 2 patients developed lower limb intermuscular venous plexus thrombosis after operation. There were no periprosthetic infection, loosening of prosthesis and other complications. The autogenous bone grafts of all patients achieved bony healing during postoperative X-ray follow-up, and the healing time was 8 to 13 months with an average of (10.1±2.3) months. The HSS score of patients increased significantly from 30 to 48 with an average of (53.4±4.2) before operation to 75 to 92 with an average of (81.2±8.4) at the final follow-up (P<0.05). The SF-36 quality of life score of patients after operation was significantly different from that before operation (P<0.05).
CONCLUSION
The technique of autogenous bone graft combined with steel plate fixation can achieve satisfactory osseointegration effect in the treatment of severe proximal tibial bone defects in primary knee arthroplasty, with less complications and obvious improvement in knee function.

OBJECTIVE:
To explore mutational characteristics of acute myeloid leukemia (AML) patients with CBFβ-MYH11+ and analyze the correlation between the mutations and partial clinical characteristics.
METHODS:
A total of 62 AML patients with CBFβ-MYH11+ were included and 51 candidate genes were screened for their mutations using targeted next-generation sequencing (NGS). The exon 12 of NPM1 , FLT3-ITD , and TAD, bZIP domains of CEBPA were detected by genomic DNA-PCR combined with sanger sequencing.
RESULTS:
Compared with RUNX1-RUNX1T1 + group, the patients with CBFβ-MYH11+ showed higher age, peripheral WBC level, initial induced complete remission (CR) rate, more commonly carried chromosomal abnormalities such as +22, and lower deletion ratio of sex chromosome (-X or -Y) (P<0.05). In AML patients with CBFβ-MYH11+, the most common mutation was NRAS , followed by KIT, KRAS , and FLT3-TKD . Compared with RUNX1-RUNX1T1+ group, NRAS and FLT3-TKD were more frequently mutated in patients with CBFβ-MYH11+ (51.6% vs 18.7%, 17.7% vs 3.8%) (P<0.05).
CONCLUSION
The genomic landscape and clinical characteristics of AML patients with CBFβ-MYH11+ are different from patients with RUNX1-RUNX1T1 +.

Objective: To investigate the regulatory effects of bio-intensity electric field on directional migration and microtubule acetylation in human epidermal cell line HaCaT, aiming to provide molecular theoretical basis for the clinical treatment of wound repair. Methods: The experimental research methods were used. HaCaT cells were collected and divided into simulated electric field group (n=54) placed in the electric field device without electricity for 3 h and electric field treatment group (n=52) treated with 200 mV/mm electric field for 3 h (the same treatment methods below). The cell movement direction was observed in the living cell workstation and the movement velocity, trajectory velocity, and direction of cosθ of cell movement within 3 h of treatment were calculated. HaCaT cells were divided into simulated electric field group and electric field treatment 1 h group, electric field treatment 2 h group, and electric field treatment 3 h group which were treated with 200 mV/mm electric field for corresponding time. HaCaT cells were divided into simulated electric field group and 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group treated with electric field of corresponding intensities for 3 h. The protein expression of acetylated α-tubulin was detected by Western blotting (n=3). HaCaT cells were divided into simulated electric field group and electric field treatment group, and the protein expression of acetylated α-tubulin was detected and located by immunofluorescence method (n=3). Data were statistically analyzed with Kruskal-Wallis H test,Mann-Whitney U test, Bonferroni correction, one-way analysis of variance, least significant difference test, and independent sample t test. Results: Within 3 h of treatment, compared with that in simulated electric field group, the cells in electric field treatment group had obvious tendency to move directionally, the movement velocity and trajectory velocity were increased significantly (with Z values of -8.53 and -2.05, respectively, P<0.05 or P<0.01), and the directionality was significantly enhanced (Z=-8.65, P<0.01). Compared with (0.80±0.14) in simulated electric field group, the protein expressions of acetylated α-tubulin in electric field treatment 1 h group (1.50±0.08) and electric field treatment 2 h group (1.89±0.06) were not changed obviously (P>0.05), while the protein expression of acetylated α-tubulin of cells in electric field treatment 3 h group (3.37±0.36) was increased significantly (Z=-3.06, P<0.05). After treatment for 3 h, the protein expressions of acetylated α-tubulin of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group were 1.63±0.05, 2.24±0.08, and 2.00±0.13, respectively, which were significantly more than 0.95±0.27 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of acetylated α-tubulin in 200 mV/mm electric field group and 300 mV/mm electric field group were increased significantly (P<0.01); the protein expression of acetylated α-tubulin of cells in 300 mV/mm electric field group was significantly lower than that in 200 mV/mm electric field group (P<0.05). After treatment for 3 h, compared with that in simulated electric field group, the acetylated α-tubulin of cells had enhanced directional distribution and higher protein expression (t=5.78, P<0.01). Conclusions: Bio-intensity electric field can induce the directional migration of HaCaT cells and obviously up-regulate the level of α-ubulin acetylation after treatment at 200 mV/mm bio-intensity electric field for 3 h.
