This article introduces Professor LIU Xing's clinical experience in treatment of peripheral facial paralysis at the recovery and sequelae stages with the combination of acupotomy, cupping and herbal medication. Based on the analysis of etiology and pathogenesis of peripheral facial paralysis, Professor LIU believes that "invasion of pathogenic wind to collaterals and obstruction of qi and blood" is crucial. Therefore, the treatment focuses on "dispelling wind and harmonizing blood". The compound therapeutic mode is proposed, with acupotomy, cupping and herbal decoction involved, in which, "three-step sequential method of acupotomy" is predominated. Firstly, in the prone position, five "feng" (wind) points are stimulated in patient, Fengfu (GV16), Fengchi (GB20), Yifeng (TE17), Bingfeng (SI12) and Fengmen (BL12). Secondly, in the lateral position, three-facial points are stimulated (FaceⅠneedle: Yangbai [GB14]-Yuyao [EX-HN4]; Face Ⅱ needle: Sibai [ST2]-Quanliao [SI18]; Face Ⅲ needle: Jiache [ST6]-Dicang [ST4]) to restore the deviated facial muscles. Finally, in the supine, two Dantian points are stimulated on the forehead and chest, respectively (upper Dantian: Yintang [GV24⁺], middle Dantian: Danzhong [CV17]), to regulate qi and blood. As the adjunctive therapies, cupping is used to remove stasis, and herbal decoction is to harmonize the body interior. In view of holistic regulation, the treatment is administered in accordance with the affected meridians, so as to expel wind, remove obstruction in collaterals and regulate qi and blood.

ObjectiveTo evaluate the effectiveness and safety of neck seven-line method combined with periauricular acupuncture as salvage treatment for sudden hearing loss in non-acute stage. MethodsSixty-six patients with non-acute stage of sudden hearing loss with a disease duration of 15-90 days were randomly divided into 33 cases each in treatment group and control group. The treatment group was given neck seven-line method combined with acupuncture at periauricular points； the control group used sham acupuncture and sham electroacupuncture at the same points. Both groups were treated 3 times a week for 6 weeks. The pure tone average hearing threshold of impaired frequencies were examined before treatment， after treatment finish and at follow-up （week 10）， and the difference between pure tone average hearing threshold of impaired frequencies before and after treatment was calculated； calculate the proportion of patients with ≥10 dB improvement in pure tone average hearing threshold of impaired frequency after treatment and at follow-up； compare the patients' Tinnitus Evaluation Scale （TEQ） scores， Chinese Medicine Quality of Life Assessment Scale （CQ-11D） health utility values and the difference between before and after treatment， and record the occurrence of adverse events. ResultsThe pure tone average of impaired frequency in the treatment group were （50.57±18.07） dB and （47.70±17.42） dB at post-treatment and follow-up respectively， and （54.38±21.77） dB and （53.36±20.99） dB in the control group at post-treatment and follow-up. Compared with the pre-treatment period， the pure tone average hearing threshold of impaired frequency in the two groups significantly decreased （P＜0.05） at post-treatment and follow-up. The difference of pure tone average hearing threshold of impaired frequency in the treatment group after treatment and at the follow-up visit compared to that before treatment was lower than those in the control group （P＜0.05）. After treatment， 13 patients （39.39%） in the treatment group and 10 patients （30.30%） in the control group showed improvement of ≥10 dB in pure tone average hearing threshold of impaired frequency； at the follow-up visit， 18 patients （54.55%） in the treatment group and 10 patients （30.30%） in the control group showed improvement of ≥10 dB in the pure tone average hearing threshold of impaired frequency， and there was no statistical significance for comparison between groups at the time of post-treatment and follow-up （P＞0.05）. The TEQ score of the treatment group significantly lower than that before treatment （P＜0.05）； the TEQ score of the treatment group and the difference between before and after treatment significantly lower than that of the control group （P＜0.05）. The difference in CQ-11D health utility values and the difference between before and after treatment were not statistically significant between the two groups （P＞0.05）. Eight cases of acupuncture-related adverse events occurred among 66 patients， including subcutaneous haematomas after needling， severe pain during needling and needle fainting， which disappeared after symptomatic treatment and did not affect the following treatment. ConclusionNeck seven-line method combined with periauricular acupuncture could be used as salvage treatment for sudden hearing loss in non-acute stage to improve the pure tone average hearing threshold of impaired frequency， alleviate tinnitus， with safety.

Objective:To explore the curative effects of ultrathin anterolateral femoral flap in one-stage split-finger repair of palmar combined with multiple finger wounds.Methods:A retrospective observational study was conducted. From October 2016 to June 2018, 20 patients with wounds on palms and multiple fingers who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 15 males and 5 females, aged 18 to 77 years. After debridement, the wound area was 8 cm×4 cm-17 cm×12 cm. The wound was repaired by ultrathin anterolateral femoral flap with area of 9 cm×5 cm to 19 cm×13 cm. According to the wound condition of finger, the finger division was performed in one stage, and the length-to-width ratio of the split-finger flap was 2.0:1.0-2.5:1.0. During the surgery, the descending branches of lateral circumflex femoral artery and accompanying vein of flap were anastomosed end-to-end to the radial artery and vein in the recipient area, respectively, and the anterolateral femoral cutaneous nerve of flap was bridged with the superficial branch of radial nerve in the recipient area. The wounds in the donor area of flap in 14 patients were sutured directly, the wounds in the donor area of flap in 3 patients were repaired by relay superficial iliac circumflex artery perforator flap, and the wounds in the donor area of flap in 3 patients were covered by free trunk medium-thick skin graft. The survival of flap, occurrence of vascular crisis and other complications, and healing of wounds in the donor area of flap were recorded. The appearance of flap, scar hyperplasia in the donor and recipient areas and the patients' satisfaction with the shape and function of the donor and recipient areas were followed up. In 1 year after surgery, the two-point discrimination distance of the flap was measured, and the recovery of hand function was evaluated by the trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association.Results:The flaps of 17 patients survived without vascular crisis or other complications after surgery. The flap of 1 patient had poor blood circulation and partial necrosis, and the wound was healed 14 days after dressing change and grafting of split-thickness skin graft from head. Two patients had mild cyanosis at the margin of flap after surgery, which disappeared spontaneously 5 days later. Incisions at donor site, relay flaps, and skin grafts of all patients survived well. After surgery, the color and texture of flap were basically the same as that of the normal skin of hand, and linear scars were observed in the donor and recipient areas. The patients were satisfied with the recovery of appearance and function of donor and recipient areas. After 1 year of follow-up, the patients' hand sensory function recovered well, the two-point discrimination distance of flap was 4-6 mm, and the recovery of hand function was evaluated as excellent in 18 cases and good in 2 cases.Conclusions:The ultrathin anterolateral femoral flap in repairing the palmar combined with multiple finger wounds in one-stage split-finger can significantly reduce the number of surgeries and improve the function and beauty of the hand, so it is worthy of clinical promotion.

The method of scoping review was used to systematically search and sort out the clinical research of oral Chinese patent medicines for ischemic stroke，to understand the scope of relevant research and the distribution of evidence. Three medical catalogs were manually searched to obtain the oral Chinese patent medicines used for ischemic stroke，and 7 databases were retrieved to obtain the clinical research including these oral Chinese patent medicines. Then the clinical evidence results were visualized by description combined with chart analysis. A total of 68 oral Chinese patent medicines were retrieved，and 1 392 articles were included，with 367 published in core journals， involving 35 oral Chinese patent medicines. The research types included randomized controlled trials，cohort studies，case series，case reports，secondary studies，adverse drug reaction reports，pharmacoeconomic evaluations，drug interactions，consensus or guidelines，non-randomized intervention studies and cross-sectional studies，of which randomized controlled trials had the largest number （283， 77.1%），followed by secondary studies and case series （25， 6.7% for each）. Among the 283 randomized controlled trials，there were 159 clinical studies in the acute phase of ischemic stroke，65 in the non-acute phase，and 59 in the unclear phase. Ten intervention control types and 20 outcome index types were summarized. Among them， the composite outcome index and surrogate outcome index were used 217 times （76.7%） and 245 times （86.6%）， respectively，followed by the degree of neurological impairment （three scales）. Future clinical research of oral Chinese patent medicines for ischemic stroke should clarify the stage of the disease，and the research design should specify the advantages of oral Chinese patent medicines intervening in ischemic stroke. Furthermore， publicly-recognized positive controls should be employed，and important clinical outcome indexes should be selected.

Objective:To analyze the efficacy and safety of radioactive 125I seed implantation in the treatment of unresectable early-stage non-small cell lung cancer (NSCLC), in order to provide data for clinical practice and relevant research. Methods:A retrospective study was conducted on the data of 39 patients with early-stage NSCLC who received CT-guided radioactive 125I seed implantation from Dec 2010 to Dec 2018 in multiple hospitals.The seed implantation process consisted of preoperative planning and design, CT-guided puncture, seed implantation, and postoperative evaluation and dose verification.The efficacy and complications of the treatment were analyzed.The clinical efficacy was evaluated by adopting the Response Evaluation Criteria in Solid Tumors (RECIST) (v1.1) and the adverse reactions were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Results:All the patients were 70 years old on average (51-85). The median lesion diameter was 2.7 cm (1.1-6.0 cm), the median seed activity was 0.7 mCi (0.6-0.8 mCi), while the median follow-up duration was 29 months (3-97 months). Meanwhile, the 1-, 3-, and 5-year overall local control rates were 89.5%, 79%, and 79%, respectively, and the 1-, 3-, and 5-year overall survival rates were 100%, 74.8%, and 49.9%, respectively.Local recurrence and distant metastasis were the main causes of failure, accounting for 17.9% (7 cases) each.The incidence of pneumothorax was 56.4% (22 cases), among which nine cases (23.1%) required invasive closed thoracic drainage.Only 1 case of grade-2 radiation pneumonia (2.6%) was observed, with no other adverse reactions such as dermatoses, esophagitis, or myelitis being discovered.As indicated by univariate analysis, the patients with KPS scores of 80-90, pathological type of adenocarcinoma, T stage of T 1-2, and D90>180 Gy exhibited better local control ( χ2=6.202, P<0.05). Meanwhile, high D90 was also associated with a higher survival rate ( χ2=6.907, P<0.05). Conclusions:Radioactive 125I seed implantation is a safe and effective treatment for unresectable early-stage NSCLC.In cases where external beam radiotherapy is not available, radioactive 125I seed implantation can be considered as one of the treatment options.Pneumothorax is the most common complication of radioactive 125I seed implantation, and adenocarcinoma (pathological type) and higher values of D90 are predictors of better local control.

Objective:To investigate the technical method and clinical efficacy of CT-guided radioactive 125I seed implantation (RISI) assisted by 3D-printed coplanar template(3D-PCT) in the treatment of metastatic tumors of chest wall, and analyze the influence of dosimetric parameters on the treatment efficacy. Methods:A retrospective analysis was conducted for 55 patients with metastatic tumors of chest wall treated with 3D-PCT-assisted 125I radioactive seed implantation in Tengzhou Central People′s Hospital from January 2014 to March 2021.Preoperative plans were made using a brachytherapy treatment planning system, and dosimetric parameters were assessed at 3d after surgery. During regular CT reexaminations after surgery, the local control rate and overall survival (OS) rate were calculated and the pain relief degree and complications were assessed. The Logrank test and Cox regression were used for univariate and multivariate analyses of local control time (LCT). Meanwhile, receiver operating characteristic (ROC) curves were plotted to analyze the critical values of dosimetric parameters and to predict the LCT. Results:The 1-, 2-, and 3-year OS rates ofthe 55 patients were 72.7% (40/55), 21.8% (12/55), and 16.4% (9/55), respectively.The local control rates of 3, 6, 12, and 24 months were 96.4%(53/55), 86.5%(45/52), 85.0%(34/40), and 91.7%(11/12), respectively. There was no statistically significant difference between postoperative and postoperative dosimetric parameters of GTV, particle number, D90, D100, V100, V150, V200, CI, EI, and HI ( P> 0.05). Compared with postoperative V90, the postoperative V90 decreased with a statistically significant difference( P=0.006). As indicated by the univariate Cox regression analysis, the pathological grade, D90, D100, V90, and V200had significant effects on the LCT( P<0.05). Among them, the pathological grade and D90 were independent influencing factors of the LCT, while the other factors showed no statistically significant difference according to the multivariate Cox regression analysis.The LCT of patients with D90≥127 Gy was significantly longer than that of patients with D90<127 Gy (χ 2=16.61, P=0.000). The pain relief rate was 80.8%(21/26) after three months. Five cases suffered from grade Ⅰ-Ⅱ radioactive dermatitis and one case experienced grade Ⅲ radioactive dermatitis. Conclusions:The 3D-PCT-assisted CT-guided 125I radioactive seed implementation can achieve precise and controllable dose and definite efficacy in the treatment of metastatic tumors of chest wall, with few complications.The LCT was remarkably prolonged in the case of D90≥127 Gy, and D90 is an independent influencing factor of the LCT.

Objectives:This study aimed to evaluate the effect of the strategies on COVID-19 outbreak control in Shenzhen, and to clarify the feasibility of these strategies in metropolitans that have high population density and strong mobility.Methods:The epidemic feature of COVID-19 was described by different phases and was used to observe the effectiveness of intervention. Hierarchical spot map was drawn to clarify the distribution and transmission risk of infection sources at different time points. The Susceptible-Exposed-Infectious-Asymptomatic-Recovered model was established to estimate case numbers without intervention and compare with the actual number of cases to determine the effect of intervention. The positive rate of the nucleic acid test was used to reflect the risk of human exposure. A survey on COVID-19 related knowledge, attitude and behaviors were used to estimate the abilities of personal protection and emergency response.Results:The epidemic of COVID-19 in Shenzhen experienced the rising, plateau and decline stage. The case number increased rapidly at the beginning, with short duration of peak period. Although the epidemic curve showed human-to-human transmission, the "trailing" was not obvious. From the spot map, during the intervention period, the source of infection was widely distributed. More cases and higher transmission risk were observed in areas with higher population density. After the effective intervention measures, both infection sources and the risk of transmission decreased. After compared with the estimated case numbers without intervention, actual number proved the COVID-19 control strategies were effective. The positive rate of nucleic acid test for high risk populations decreased and no new cases reported since February 16. Shenzhen citizens had high knowledge, attitude and behavior level, and high protection ability and emergency response.Conclusions:Although the response initiated by the health administration department played a key role at the early stage of the epidemic, it was not enough to contain the outbreak of COVID-19. The first-level emergency response initiated by provincial and municipal government was effective and ensured the start of work resumption after the Spring Festival. Metropolitans like Shenzhen can also achieve the goals of strategies and measures for containment and mitigation of COVID-19.

Two new SAM-dependent methyltransferase encoding genes (fvsmt1 and fvsmt2) were identified from the genome of Flammulina velutipes. In order to make a comprehensive characterization of both genes, we performed in silico analysis of both genes and used qRT-PCR to reveal their expression patterns during the development of F. velutipes. There are 4 and 6 exons with total length of 693 and 978 bp in fvsmt2 and fvsmt1, respectively. The deduced proteins, i.e., FVSMT1 and FVSMT2 contained 325 and 230 amino acids with molecular weight 36297 and 24894 Da, respectively. Both proteins contained a SAM-dependent catalytic domain with signature motifs (I, p-I, II, and III) defining the SAM fold. SAM-dependent catalytic domain is located either in the middle or at the N-terminal of FVSMT2 and FVSMT1, respectively. Alignment and phylogenic analysis showed that FVSMT1 is a homolog to a protein–arginine omega-N-methyltransferase, while FVSMT2 is of cinnamoyl CoA O-methyltransferase type and predicted subcellular locations of these proteins are mitochondria and cytoplasm, respectively. qRT-PCR showed that fvsmt1 and fvsmt2 expression was regulated in different developmental stages. The maximum expression levels of fvsmt1 and fvsmt2 were observed in stipe elongation, while no difference was found in mycelium and pileus. These results positively demonstrate that both the methyltransferase encoding genes are involved in the stipe elongation of F. velutipes.

OBJECTIVETo compare the surgical safety and short-term efficacy of minilaparotomy and laparoscopic approach for curative resection of rectal cancer.

METHODSThe retrospective cohort study was adopted. A review of patients scheduled to undergo a curative resection of rectal cancer via minilaparotomy or laparoscopic approach at Department of Colorectal Surgery of Changhai Hospital from June 2016 to May 2017 was carried out. All the patients were confirmed as rectal cancer by postoperative pathology. The following patients were excluded from the study: patients who had acute complete obstruction or perforation; patients underwent Miles or Hartmann procedure; patients who required an elongation of the skin incision in minilaparotomy or a conversion from laparoscopic to open surgery. Finally, 216 patients were enrolled in this study, of whom 143 were performed with minilaparotomy approach (minilaparotomy group) and 73 with laparoscopic approach (laparoscopic group) for curative resection of rectal cancer. For the minilaparotomy technique, a 7 cm longitudinal midline incision was made between the pubic symphysis and umbilicus; a wound retractor was applied to the edge of the wound; lymph node dissection around the inferior mesenteric and artery high ligation of inferior mesenteric artery were performed; by moving the minilaparotomy wound laterally and caudad or cephalad with the S-shaped hook, cautious mobilization of the relevant segment of the bowel loop was performed; bowel anastomosis was achieved by using the double-stapled technique; the gap of the pelvic floor peritoneum and mesentery were routinely closed by the absorbable surgical suture in cases with middle and low position rectal cancer. The surgical safety, the condition of resuming and the morbidity of postoperative complication were compared between the two groups.

RESULTSThere were 145 men and 71 women. Age ranged from 26 to 87 years, with of mean age of 61 years. According to the TNM stage grouping, there were 61 patients with stage I(, 62 with stage II(, 85 with stage III(, and 8 with stage IIII( disease, respectively. These two groups did not differ significantly in terms of age, sex, body mass index, site of tumor, TNM stage(all P>0.05). All the patients completed the operation successfully. The median operation time of minilaparotomy group was significantly shorter than that of laparoscopic group [164(80-296) minutes vs. 230(90-665) minutes, Z=4.410, P=0.000]. The intraoperative medical consumable expense [11000(7000-22000) yuan vs. 23000(12000-47000) yuan, Z=11.759, P=0.000] and the total hospitalization expense [44000(22000-146000) yuan vs. 57000(45000-126000) yuan, Z=9.637, P=0.000] were significantly lower in the minilaparotomy group. There were no significant differences between the two groups in terms of operative blood loss, number of harvested lymph nodes, distance of distal resection margin, positive rate of circumferential resection margin (all P>0.05). The rate of postoperative complication in minilaparotomy group was 7.0%(10/143) and in laparoscopic group was 9.6%(7/73) without significant difference (χ=0.449, P=0.503). There were 2 patients in each group who required readmission to the hospital within postoperative 30 days. The cause of readmission was ileus or acute hyponatremia in minilaparotomy group, and ileus or pevic infection in laparoscopic group. One patient died of brain death caused by acute pulmonary embolism during the perioperative period in minilaparotomy group.

CONCLUSIONSThe minilaparotomy approach for curative resection of rectal cancer is safe and feasible. As compared with laparoscopic approach, it is advantageous to achieve minimal invasiveness and early recovery, but much cheaper and less time consuming.
