Objective:To investigate the clinical effect of three-dimensional(3D) flap model accurately designed before the operation in repairing irregular wounds of limbs with anterolateral thigh(ALT) perforator flap.Methods:The data of patients with ALT flaps designed with 3D printing technology to repair irregular soft tissue defects of limbs in Suzhou Ruihua Orthopedic Hospital from January to October 2022 were retrospectively analyzed. After the wound was scanned by 3D scanner before surgery, the wound model was printed. The ALT flap was precisely designed and harvested for covering the wound according to the body surface projection of the perforator vessel in the anterolateral femoral region located by color Doppler ultrasound before surgery. The survival of the flap, the healing of the donor and recipient sites and the occurrence of complications were observed and followed up after the operation. The effect of wound repair was evaluated by the comprehensive efficacy evaluation scale of the skin flap. The total score was 100 points, which was divided into excellent (90-100 points), good (75-89 points), fair (60-74 points) and poor (< 60 points).Results:A total of 34 patients were enrolled, including 26 males and 8 females, aged 18-75 years, with an average age of 45.5 years. Injury sites: wrist in 17 cases, foot in 10 cases, ankle in 7 cases. The operation time was 2.0-4.5 h (mean 3.3 h), and all donor sites were sutured directly. Vascular crisis occurred in 2 cases after skin flap transplantation. After surgical exploration, the transplanted skin flap survived, and the other skin flaps survived successfully. All 34 patients were followed up for 6 to 10 months, with an average of 8 months. All the donor sites of the skin flap healed primarily, and the wound healing time of the recipient site was 10-44 days, with an average of 20 days. At the last follow-up, the skin flap was good in color and texture, and the sensation returned to S1 and S2 grades. There were scars left in the donor site, no cicatricial contracture, pain and other discomfort, and no other serious complications. The results of flap evaluation were 80-91 points, with an average of 86 points. Among them, 25 cases were excellent, 6 cases were good, 3 cases were fair, and the excellent and good rate was 91%(31/34).Conclusion:The application of 3D printing technology assisted the design of ALT perforator flap to repair irregular wounds of limbs can significantly reduce the intraoperative design time of the flap, which is in line with the concept of precise design and incision of the flap, and has good clinical effect, and can effectively reduce the trauma and complications of the donor site.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the effects of anterolateral femoral perforator flaps pedicled with oblique branch of lateral circumflex femoral artery and carrying fascia lata in repairing destructive wounds and rebuilding function of hands or feet.Methods:This study was a retrospective observational study. From January 2022 to March 2023, 16 patients with destructive wounds in hands or feet combined with extensor tendon defects who met the inclusion criteria were admitted to Suzhou Ruihua Orthopedic Hospital, including 12 males and 4 females, aged 3 to 63 years. The wounds were located on the hands in 12 cases and on the feet in 4 cases. The number of defective extensor tendon ranged one to five, and the length of the defect ranged from 2.5 to 6.0 cm. The wound area was 11.0 cm×5.5 cm to 29.0 cm×9.5 cm after debridement. The wounds were repaired with anterolateral femoral perforator flaps pedicled with oblique branch of lateral circumflex femoral artery and carrying fascia lata, and the flap area was 12.0 cm×6.5 cm to 30.0 cm×11.0 cm. The fascia lata was used to repair the extensor tendon defects, and the harvesting area of fascia lata was 8.0 cm×3.0 cm to 12.0 cm×8.0 cm. The wounds in flap donor areas in 15 patients were sutured directly, and the wound in flap donor area in 1 patient was covered with medium-thickness skin graft from lower abdomen. The survival of flaps and the wound healing in donor and recipient areas of flaps were observed within 1 week after operation. The number of patients who underwent thinning and plastic surgery or tenolysis was recorded during postoperative follow-up. At the last follow-up, the recovery of sensory function of the transplanted flaps on hands or feet was evaluated, the efficacy of flap repair was evaluated according to the comprehensive flap evaluation scale, and the function of hands was evaluated according to the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association. The following two indexes were compared, including the measured total active motion of the injured fingers and the foot function assessed using Maryland foot function scale between before surgery and at the last follow-up.Results:Arterial crisis occurred in flaps in 2 patients after operation, and the flaps survived after timely exploration; the flaps in the rest patients survived well after operation. No obvious scar hyperplasia or ulceration was observed in donor and recipient areas of flaps after operation. All patients were followed up for 8 to 16 months, of which 6 patients underwent flap thinning and plastic surgery 6 to 7 months after operation, and 4 patients underwent tenolysis 3 to 6 months after operation. At the last follow-up, the recovery of sensory function of flaps reached S1 level in 5 cases and S2 level in 11 cases, and the two-point discrimination only had 1 point. The efficacy of flap repair scored 80 to 91, which were evaluated as excellent in 5 cases, good in 9 cases, and acceptable in 2 cases. The hand function was evaluated as excellent in 5 cases, good in 5 cases, and acceptable in 2 cases. The active extension function of the injured finger/toe was reconstructed successfully, and the total active motion of the injured finger was (225±22)° at the last follow-up, which was significantly higher than (117±20)° before surgery ( t=119.59, P<0.05); the foot function score was 86±7 at the last follow-up, which was significantly higher than 29±7 before surgery ( t=222.68, P<0.05), and the foot function was evaluated as excellent in 2 cases, good in 1 case, and acceptable in 1 case. Conclusions:The operation of harvesting the anterolateral femoral perforator flap pedicled with oblique branch of lateral circumflex femoral artery is relatively simple. After the wounds on hands or feet being repaired with the flaps, the appearance and function are good, with no obvious scar hyperplasia in donor and recipient areas of flaps. The fascia lata carried by the flap can repair the extensor tendon defect at the same time and improve the movement of the finger/toe.

Objective: To investigate the clinical characteristics and maternal and fetal prognosis of pregnant women with acute fatty liver of pregnancy (AFLP). Methods: The clinical data of 86 AFLP pregnant women admitted to the Third Affiliated Hospital of Guangzhou Medical University from September 2017 to August 2022 were collected, and their general data, clinical characteristics, laboratory tests and maternal and fetal outcomes were retrospectively analyzed. Results: (1) General information: the age of the 86 pregnant women with AFLP was (30.8±5.4) years, and the body mass index was (21.0±2.5) kg/m². There were 50 primiparas (58.1%, 50/86) and 36 multiparas (41.9%, 36/86). There were 64 singleton pregnancies (74.4%, 64/86) and 22 twin pregnancies (25.6%, 22/86). (2) Clinical characteristics: the main complaints of AFLP pregnant women were gastrointestinal symptoms, including epigastric pain (68.6%, 59/86), nausea (47.7%, 41/86), anorexia (46.5%, 40/86), vomiting (39.5%, 34/86). The main non-gastrointestinal symptoms were jaundice of skin and/or scleral (54.7%, 47/86), edema (38.4%, 33/86), fatigue (19.8%, 17/86), bleeding tendency (16.3%, 14/86), polydipsia or polyuria (14.0%, 12/86), skin itching (8.1%, 7/86), and 17.4% (15/86) AFLP pregnant women had no obvious symptoms. (3) Laboratory tests: the incidence of liver and kidney dysfunction and abnormal coagulation function in AFLP pregnant women was high, and the levels of blood ammonia, lactate dehydrogenase and lactic acid were increased, and the levels of hemoglobin, platelet and albumin decreased. However, only 24 cases (27.9%, 24/86) of AFLP pregnant women showed fatty liver by imageology examination. (4) Pregnancy outcomes: ① AFLP pregnant women had a high incidence of pregnancy complications, mainly including renal insufficiency (95.3%, 82/86), preterm birth (46.5%, 40/86), hypertensive disorders in pregnancy (30.2%, 26/86), gestational diabetes mellitus (36.0%, 31/86), fetal distress (24.4%, 21/86), pulmonary infection (23.3%, 20/86), disseminated intravascular coagulation (16.3%, 14/86), multiple organ dysfunction syndrome (16.3%, 14/86), hepatic encephalopathy (9.3%, 8/86), and intrauterine fetal death (2.3%, 2/86). ② Treatment and outcome of AFLP pregnant women: the intensive care unit transfer rate of AFLP pregnant women was 66.3% (57/86). 82 cases were improved and discharged after treatment, 2 cases were transferred to other hospitals for follow-up treatment, and 2 cases (2.3%, 2/86) died. ③ Neonatal outcomes: except for 2 cases of intrauterine death, a total of 106 neonates were delivered, including 39 cases (36.8%, 39/106) of neonatal asphyxia, 63 cases (59.4%, 63/106) of neonatal intensive care unit admission, and 3 cases (2.8%, 3/106) of neonatal death. Conclusions: AFLP is a severe obstetric complication, which is harmful to mother and fetus. In the process of clinical diagnosis and treatment, attention should be paid to the clinical manifestations and laboratory tests of pregnant women, early diagnosis and active treatment, so as to improve maternal and fetal outcomes.

Abstract： Objective　To analyze the species distribution of microorganisms in culture tubes reported positive byBACTEC™ MGIT960 (hereafter referred to as "MGIT960") after species identification using matrix-assisted laser desorption/ionization time of flight massspectrometry (MALDI-TOF MS) technique. Methods　From 2021 to 2022, a total of 2 662 positive tubes reported by the MGIT 960 instrument at Tuberculosis Reference Laboratory of Tianjin Center for Tuberculosis Control were collected. Liquid cultures were independently inoculated to blood plate and neutral L-J medium, and the resulting isolate strains were identified using the MALDI-TOF MS method. According to the MALDI-TOF MS results, the non-repetitive results of the same patient on the same culture medium were analyzed for the composition ratio of strain distribution. For the strains not identified by MALDI-TOF MS, 38 strains were selected for 16S rRNA gene sequencing. Results　A total of 605 isolates were obtained from blood plates, and 501 of those were analyzed. Among them, Mycobacterium accounted for 17.76% (89/501), predominant by Mycobacterium abscess 10.18% (51/501) and Mycobacterium fortuitum 3.19% (16/501). Bacteria other than Mycobacterium accounted for 68.06% (341/501), with the main ones being Nocardia farcinica 15.57% (78/501), Gordonia sputa 9.38% (47/501) and Gordonia bronchialis 7.58% (38/501). There were 71 unidentifiable strains, making up 14.17% (71/501). A total of 2 378 strains were isolated from neutral L-J mediums, 1 748 of which were used in the incoming analysis. Among these, 78.72% (1 376/1 748) were Mycobacterium, 60.53% (1 058/1 748) were Mycobacterium tuberculosis (MTB), 4.69% (82/1 748) were Mycobacterium chimaer intracellulare group and 3.55% (62/1 748) were Mycobacterium Lentiflavum. Bacteria other than Mycobacterium accounted for 17.11% (299/1 748) in neutral L-J medium isolates, with Nocardia farcinica 4.35% (76/1 748), Gordonia sputa 2.69% (47/1 748) and Gordonia bronchialis 2.12% (37/1 748) as the main species. There were 73 strains that couldn't be identified, comprising 4.18% (73/1 748). The 38 strains that not identified by MALDI-TOF MS were all found to be Actinobacteria and Firmicutes by sequencing. Conclusions　A variety of nontuberculous Mycobacterium and bacteria other than Mycobacterium were found in the positive culture tubes reported by the MGIT960 instrument, most of which could be quickly identified by mass spectrometry. Bacteria other than Mycobacterium are mainly Nocardia and Gordonia, which should be paid attention to in differential diagnosis.

To investigate the relationship between serum uric acid to creatinine ratio (SUA/Cr) and metabolic syndrome (MS) and other indexes on physical examination population in Nantong area. Using the method of cross-sectional study, 8 148 physical examiners in the physical examination center of the Affiliated Hospital of Nantong University from January 2017 to April 2020 were used as the research objects, and the clinical data and serum biochemical indicators such as smoking and alcohol addiction, physical examination and so on were collected. According to the standard diagnosis of MS of Diabetes Society of Chinese Medical Association, the patients were grouped according to the quartile of SUA/Cr and the clinical data of each group were compared. Pearson correlation analysis and logistic regression analysis were used to explore the correlation between SUA/Cr and clinical indicators and the relationship between SUA/Cr and the risk of MS. The results showed that UA and SUA/Cr were the lowest in normal metabolism group, followed by abnormal metabolism group and the highest in MS group, The difference between the two groups was statistically significant (H=919.21 and 629.34, P<0.001). According to the SUA/Cr quartile, the population was divided into four groups. After adjusting for gender, age, smoking history and drinking history, SUA/Cr in group Q₁ was positively correlated with BMI and TG (r=0.061 and 0.080, P<0.05), but negatively correlated with HDL-C (r=-0.057, P<0.05). Multivariate logistic regression results showed that after adjusting for age, sex, smoking history and drinking history, the risk of MS for BMI, SBP, DBP, FBG, TG, HDL-C and SUA/Cr [OR (95%CI)] were: 1.44 (1.41-1.47), 1.07 (1.06-1.07), 1.10 (1.10-1.11), 1.83 (1.73-1.92), 1.89 (1.79-1.99), 0.08 (0.06-0.10) and 1.54 (1.47-1.62). Compared with SUA/Cr group Q₁, the risk of MS in group Q₂, Q₃ and Q₄ increased by 75%, 162% and 346%, respectively. In conclusion, there was an independent positive correlation between SUA/Cr and MS risk in Nantong area.

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

Objective: To study the anti-hypertrophic scar effect of the six-herb Chinese medicine composition (SCMC) ointment on the rabbit ear hypertrophic scar models. Methods: The optimal formulation of SCMC ointment matrix was screened by the orthogonal designs and a series of evaluation tests. The SCMC ointment was prepared through emulsifying method. The rabbit ear hypertrophic scar models were established and used to investigate the anti-hypertrophic scar effect of SCMC ointment. Results: Our results demonstrated that all the quality control indications of the SCMC ointment met the requirements. Anti-hypertrophic scar activity results showed that all the rabbit ear scar tissues appeared different degrees of shrink and fading, and took an unobvious but palpable shift from hard to soft texture with the low, middle and high concentration SCMC ointments treatments in vivo. Additionally, on 21st day the scar area and thickness in different concentrations of SCMC ointment groups were significantly reduced than control group, in a concentration-dependent manner. The immunohistochemical results also indicated that the SCMC ointment had good anti-hypertrophic scar properties and could inhibit hypertrophic scar formation. Conclusion: The SCMC ointment could improve the blood circulation condition of hypertrophic scar tissues. Our research has demonstrated the Chinese medicine composition ointment with good anti-hypertrophic scar properties that could be used to treat hypertrophic scars. Meanwhile, it provides a theoretical basis for further clinical application.
