Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

OBJECTIVE To systematically evaluate the safety of paroxetine in the treatment of pregnant patients with depression in the second and third trimesters of pregnancy， and provide reference for rational clinical use of it. METHODS Retrieved from Cochrane Library， PubMed， Embase， VIP， CNKI， Wanfang database and SinoMed database， by manual search， randomized controlled studies or observational studies were collected on depression patients who were given paroxetine vs. selective serotonin reuptake inhibitor （SSRI） in the second and third trimesters of pregnancy during the inception to Aug. 2022. Methodological qualities of the included studies were assessed by Cochrane Handbook 5.1.0 or Newcastle-Ottawa Scale （NOS）. Meta-analysis was performed with RevMan 5.4.1 software. RESULTS Finally， 9 observational studies were included， and all included studies were of high quality in NOS scale. Meta-analysis was performed on 8 cohort studies. Meta-analysis showed that the total incidence of adverse pregnancy outcomes of mothers and infants [RR＝0.99， 95%CI（0.89，1.10），P＝0.87]， total incidence of maternal adverse pregnancy outcomes [RR＝0.98， 95%CI （0.87，1.10）， P＝0.69] and premature birth [RR＝0.89， 95%CI （0.43， 1.83）， P＝0.75] in the second and third trimesters of pregnancy were lower than that with other SSRI， without statistical significance. The incidence of neonatal complications with paroxetine in the second and third trimesters of pregnancy was higher than that with other SSRI， but the difference was not statistically significant [RR＝1.02， 95%CI （0.82，1.29）， P＝0.84]. One study reported that the incidence of neonatal pulmonary hypertension in paroxetine group was higher than that in other SSRI group （0.4% vs. 0.3%）. CONCLUSIONS The safety of peroxetine in the second and third trimesters of pregnancy is comparable with that of other SSRI， but it is necessary to be alert to the occurrence of neonatal pulmonary hypertension.

【Objective】 In an effort to prevent transfusion-transmitted hepatitis B infection, universal HBsAg screening, HBsAg+ MP nucleic acid test(NAT) for HBV and HBsAg + individual(ID) NAT were analyzed for cost-effectiveness. 【Methods】 On the basis of screening data and the documented parameter, the number of window period infections, chronic infections and occult infections was constructed, and cost-benefit analysis was conducted. 【Results】 Of 132 208 donations, the yield rate of ID NAT for HBsAg-/DNA+ (0.11%) was significantly higher than HBsAg+ MP NAT(0.058%). Furthermore, the predicted preventing transfusion transmitted HBV cases by ID NAT is 1.25 times as that by MP-6 NAT, so did the benefits. The cost-benefit of the three screening models were 1∶63.6、1∶28.6 and 1∶53.4. 【Conclusion】 Universal HBsAg in combination with ID HBV NAT screening was the most effective among all screening strategy. It is necessary to applied HBsAg and ID HBV NAT screening for the safety of blood transfusion.

Objective:To investigate the clinical characteristics and perinatal outcomes of pregnancy with placental cystic lesions.Methods:A retrospective study was carried out on 48 pregnant women diagnosed as pregnancy complicated with placental cystic lesions from January 2000 to January 2020 at the Women′s Hospital, Zhejiang University School of Medicine. The clinical features, pathological diagnosis and perinatal outcome were analyzed.Results:The age of 48 cases was (30±5) years, and the diagnostic gestational week of ultrasound was (24±8) weeks. Twenty-five cases in which showed a cystic mass at the fetal surface were diagnosed as placental cyst. The live birth rate was 100% (25/25) and the premature birth rate was 20% (5/25). Twenty-three cases showed “honeycomb like” cystic echo. Cystic lesions of 10 cases were located in the uterine cavity connected with the margin of the normal placenta, and finally diagnosed as hydatidiform mole and coexisting fetus (HMCF). Six cases of HMCF terminated pregnancy, and the live birth rate was 4/10, the premature delivery rate was 2/4. Cystic lesions of 13 cases were located in the placenta substance, and finally diagnosed as 4 cases of placental mesenchymal dysplasia (PMD) and 9 cases of focal chorionic edema; the live birth rate was 6/13 and the premature delivery rate was 4/6. The median hCG was lower in focal chorionic edema group [80 kU/L (60-110 kU/L)] than in the groups of HMCF [240 kU/L (180-430 kU/L)] and PMD [360 kU/L (210-700 kU/L)], and the differences were statistically significant (all P<0.01). Conclusions:For pregnancy complicated with placental cystic lesions, prenatal ultrasound should be performed to evaluate the shape, location and blood flow of the lesions. Maternal serological examination and invasive prenatal diagnosis are helpful for prenatal diagnosis and treatment. Due to the difference of perinatal outcomes, maternal and fetal complications, individualized pregnancy management should be carried out.

Objective: To investigate the clinical value of gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery on patients with cholecystolithiasis. Methods: A retrospective study was performed on data of 15 patients with cholecystolithiasis, who underwent gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery from April 2018 to July 2018. The operative data, including situation of operation, operative time, intraoperative hemorrhage, and postoperative complications were recorded. Results: The procedure was performed successfully in all patients with a mean operative time of 108±12 min (ranged from 92-129 min). The intraoperative hemorrhage was 10-30 mL. Eight patients suffered from slight right upper abdominal pain, and 7 patients felt slight pain in umbilical a week after surgery. No fever, incision infection, umbilical hemia, peritonitis, and ascites were reported. The clear-liquid diet was recommended for one day after operation, and postoperative activity was allowed since the second day after operation. All patients were discharged on the fourth or fifth day, and all recovered to their normal life at one week after discharge. Follow-up showed that the scar was small and hidden in umbilical without visible incision after one month. Ultrasonic examination results showed that gallbladder contractile function worked perfectly in four patients and no gallbladder stone was found after three months. Conclusion Gallbladder-preserving cholelithotomy by natural orifice transumbilical endoscopic surgery is a safe and effective option for patients with cholecystolithiasis, provides excellent cosmetic outcomes, and can be appropriately carried out under the strict control of surgical indications.

Objective To investigate the clinical features, diagnosis and treatments of heterotopic pregnancy(HP)and demonstrate the outcomes of HP after the surgical treatment of ectopic pregnancies. Methods A retrospective analysis was performed on 144 cases of HP in Women′s Hospital, School of Medicine, Zhejiang University from January 2003 to December 2016. Results (1)Clinical features of HP:the average age of patients was(30.8±3.8)years old, body mass index(BMI)was(21.9±2.9)kg/m2, and was diagnosed at(6.5±1.3)weeks gestational age. Four patients(2.8%)were naturally pregnant, 10 patients (6.9%)received ovulation induction, and 130 patients(90.3%)had received infertility treatments. Fifty-one patients(35.4%)had no clinical symptoms, and 93 patients(64.6%)had clinical symptoms included vaginal hemorrhage, abdominal pain and hemorrhagic shock caused by intraperitoneal hemorrhage. The location of ectopic pregnancy was most common in the fallopian tubes(59.0%, 85/144)and the interstitial part (33.3%, 48/144). (2)Ectopic pregnancy treatment of HP: thirteen patients underwent expectation treatment, and the remaining 131 cases underwent surgical treatment, including laparoscopy(n=56), laprotomy(n=52), and fetal reduction (n=23). Among the 131 patients underwent surgery, intrauterine pregnancy were found inevitable abortion in 6 cases preoperatively. The total early abortion rate after surgery was 14.4%(18/125); the second operation rate was 3.1%(4/131).(3)Intrauterine pregnancy outcome of HP:120 intrauterine fetal were survival, the total live birth rate was 83.3%(120/144).One hundred and seven intrauterine fetal were survival after operation and the live birth rate after operation was 85.6%(107/125). Twenty-nine cases were premature delivery and the premature delivery rate was 24.2%(29/120). There was no significant differences between tubal HP and interstitial HP group in the preterm birth rate [25.8%(16/62) vs 26.3% (10/38); χ2=0.003, P>0.05]. Cesarean section rate of delivery in interstitial HP group was significantly higher than that in tubal HP group [97.4%(37/38)vs 59.7%(37/62)], and the difference was statistically significant(χ2=17.400, P<0.05). Conclusions The clinical manifestations of HP are diversified, combining of high risk factors, clinical symptoms and ultrasonography could improve the accuracy of diagnosis. Different method has been used to treat HP, such as laparoscopic or laparotomy and fetal reduction, and there are varying degrees of failure rate and postoperative abortion rate. We should consider carefully to adopt expectant management. Through individualized treatment, most HP could get good perinatal outcomes.

This paper aims to explore the feasibility of building a finite element model of left atrial diverticulum (LAD) using reverse engineering software based on computed tomography (CT) images. The study was based on a three-dimensional cardiac CT images of a atrial fibrillation patient with LAD. The left atrium and LAD anatomical features were accurately reproduced by using Geomagic Studio 12 and Mimics 15 reverse engineering software. In addition, one left atrial model with LAD and one without LAD were created with ANSYS finite element analysis software, and the validity of the two models were verified. The results show that it is feasible to establish the LAD finite element model based on cardiac three-dimensional CT images using reverse engineering software. The results of this paper will lay a theoretical foundation for further hemodynamic analysis of LAD.

OBJECTIVE: To investigate the preservation of the structure and function of the trachea and larynx, the management of laryngotracheal defect when trachea and larynx was involved. METHOD: To review the management and clinical results of 13 cases of thyroid papillary carcinoma with larynx and trachea involvement, the preservation of laryngotracheal structure and relative defect reconstruction of our department from 2007-2014. Those patients being performed total laryngectomy was excluded. 3 males and 10 females, aged from 46 to 67 years old with median age of 53 were included. Among them 8 cases were recurrent. The extent of the tumor foci was estimated with the help of computed tomography and laryngofiberoscope before surgery. Selective neck dissection, total thyroidectomy and related laryngotracheal resection was performed for the first time operation patient, while selective neck dissection, recurrent foci and related larynx and trachea resection was performed for those recurrent patients. Three kinds of modalities were applied to manage the laryngotracheal defect including to reconstruct with pedicled sternocleidomastoid clavicular periosteocutaneous flap, pedicled trapizius muscular flap and to preserve the remaining larynx and trachea and perform a stoma of larynx and trachea which repaired by a second-stage procedure. The patients were followed-up from half an year to 3 years. RESULT: Ten patients out of 13 decannulated while another 3 cases, 2 of which were performed local flap to reduce the stoma, wore tracheal tubes all time. CONCLUSION Either flap transfer or laryngotracheal stoma before second stage repair might preserve partial laryngotacheal anatomy and function in selected cases thus improve the life quality of the patients.

OBJECTIVE: To investigate the feasibility of utilizing pedicled sternocleidomastoid clavicular periosteocutaneous flap to reconstruct the laryngotracheal defect after tumor resection. METHOD: To review 6 cases of laryngotracheal defect resulting from resction of thyroid papillary carcinoma(4/6) or subglottic laryngeal carcinoma (2/6) (T1~2N1~2M0 , UICC,2002), laryngotracheal stenting was also employed in all cases. Half a year after surgery, the stoma was sutured if no local recurrence took place and safety was proved after tracheal tube had been obstructed for days. The follow-up time lasted from half a year to 3 years. RESULT: Four cases (4/6) were extubated successfully without event, one case could intermittently plug the tracheal tube. One patient couldn't breath with tracheal tube plugging. CONCLUSION To reconstruct the laryngotracheal defect with pedicled sternocleidomastoid clavicular.periosteocutaneous flap after tumor resection is feasible in selected cases and could get satisfactory clinical results either in respiration or phonation.

OBJECTIVE: To investigate cervical esophageal reconstruction by means of laryngo-tracheal flap after resection of hypopharyngeal carcinoma with cervical esophageal involvement. METHOD: Eleven cases of hypopharyngeal carcinoma with cervical esophageal involvement. Unilateral piriform sinus and cervical esophagus were involved in 8 cases (8/11) while bilateral piriform sinus, posterior pharyngeal wall and cervical esophagus were involved in 3 cases. After resection of laryngeal, pharyngeal and esophageal tumors and bilateral neck dissection, direct anastomosis of larynx and trachea with esophagus of cervico-thoracic segment was performed if circular structure of larynx and trachea could be preserved (3/11), pectoralis major myocutaneous flap was employed if only part of pharynx and larynx could be preserved (8/11). Postoperative radiochemotherapy was adopted and follow-up lasted for 1-5 years. RESULT: All cases healed without event except for one case of pharyngeal fistula and one case of chylous fistula which also healed after about 2 weeks dressing change. All patients got normal diet without anastomotic stricture. There was no recurrence in 6 patients at the 3 years follow-up, 4 patients had metastases in the neck and 1 patient had thoracic esophageal carcinoma with hepatic metastasis arid gave up further treatment. The overall 3-year survival rate was 54.5%. CONCLUSION Using laryngo-tracheal flap to reconstruct cervical esophagus after resection of hypopharyngeal carcinoma with cervical esophageal involvement is a recommendable method that is simple in processing, reliable in effect and less in postoperative complications.
