ABSTRACT
@#Objective To summarize the experience of robot-assisted lung basal segmentectomy, and analyze the clinical application value of intersegmental tunneling and pulmonary ligament approach for S9 and/or S10 segmentectomy. Methods The clinical data of 78 patients who underwent robotic lung basal segmentectomy in our hospital between January 2020 to May 2022 were retrospectively reviewed. There were 32 males and 46 females with a median age of 50 (33-72) years. The patients who underwent S9 and/or S10 segmentectomy were divided into a single-direction group (pulmonary ligament approach, n=19) and a bi-direction group (intersegmental tunneling, n=19) according to different approaches, and the perioperative outcomes between the two groups were compared. Results All patients successfully completed the operation, without conversion to thoracotomy and lobectomy, serious complications, or perioperative death. The median operation time was 100 (40-185) min, the blood loss was 50 (10-210) mL, and the median number of dissected lymph nodes was 3 (1-14). There were 4 (5.1%) patients with postoperative air leakage, and 4 (5.1%) patients with hydropneumothorax. No patient showed localized atelectasis or lung congestion at 6 months after the operation. Further analysis showed that there was no significant difference in the operation time, blood loss, thoracic drainage time, complications or postoperative hospital stay between the single-direction and bi-direction groups (P>0.05). However, the number of dissected lymph nodes of the bi-direction group was more than that of the single-direction group [6 (1-13) vs. 5 (1-9), P=0.040]. Conclusion The robotic lung basal segmentectomy for pulmonary nodules is safe and effective. The perioperative results of robotic S9 and/or S10 complex segmentectomy using intersegmental tunneling and pulmonary ligament approach are similar.
ABSTRACT
Objective:To investigate characteristics and differences of cerebral glucose metabolism in patients with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis from the perspective of different trigger factors of antibodies. Methods:A total of 15 patients (8 males, 7 females, age (30.5±17.7) years) with anti-NMDAR encephalitis between January 2016 and January 2019 in Huashan Hospital, Fudan University were recruited retrospectively. All patients underwent resting state cerebral 18F-FDG PET imaging. The characteristics of brain glucose metabolism were analyzed, and the SUV ratio (SUVR) was semi-quantitatively compared with that in 12 healthy subjects (HS; 7 males, 5 females, age (51.5±9.6) years). Independent-sample t test was used to analyze the data. Results:Among 15 patients, 5 patients were viral encephalitis-related anti-NMDAR encephalitis, showing focal decreased metabolism in unilateral temporal lobe or basal ganglia (SUVR: patients: 0.659±0.219; HS: 1.754±0.203; t=-9.58, P<0.001), with increased metabolism in contralateral temporal lobe or basal ganglia (SUVR: patients: 2.275±0.244; HS: 1.960±0.227; t=2.55, P=0.022) in 18F-FDG PET imaging. Six patients were cryptogenic anti-NMDAR encephalitis, showing asymmetric increased metabolism in frontal, temporal, parietal and basal ganglia (SUVR: patients: 2.482±0.395; HS: 1.754±0.203; t=5.23, P<0.001), with decreased metabolism in bilateral occipital lobes. The remaining 4 cases were paraneoplastic origin accompanied by teratoma, showing increased metabolism in bilateral temporal and basal ganglia (SUVR: patient: 2.359±0.181; HS: 1.960±0.227; t=3.16, P=0.007), with mild decreased metabolism in bilateral occipital lobe. Conclusions:The abnormal changes of cerebral glucose metabolism in patients with anti-NMDAR encephalitis can be divided into at least three patterns according to different trigger factors. A comprehensive understanding of these characteristic metabolic changes is helpful for detecting disease, and may provide potential value in indicating different causes.

Drug use during pregnancy is unavoidable. Therefore, it is vitally important for medical workers to help pregnant women take drugs correctly to reduce the incidence of spontaneous abortion, premature birth, and low birth weight. In our study, drug screening model with induced pluripotent stem cells (iPSCs) was used to find some improper drugs which will result in woman's abortion. With 3D culture in vitro, iPSCs can form embryoid bodies (EBs) and cerebral organoids, which simulated in vitro development of early embryos, from inner cell mass to germ-layer differentiation. In the experiment, EBs were exposed to mifepristone (RU486), and three experimental groups were divided randomly. They were control group (without RU486), low-dose group (L-RU486, 10 μg·mL-1), and high-dose group (H-RU486, 20 μg·mL-1). After mifepristone exposure, EBs were observed at days 5, 8, and 11, including size of EB, cell apoptosis, and differentiation of germ layers, by using inverted optical microscope, TUNEL assay, and immunofluorescent staining. The results showed that through 3D culture, iPSCs could develop into embryoid bodies, neural rosettes, and finally cerebral organoids. After mifepristone exposure, EBs' sizes were decreased (P < 0.01); the levels of cell apoptosis in EBs were increased after mifepristone exposure (P < 0.01); the development of EBs' germ layer was affected. Mifepristone exposure could inhibit the proliferation of embryonic stem cells, reduce the differentiation of ectoderm (P < 0.01) and promote the development of mesoderm (P < 0.05). In conclusion, iPSCs can be used as a screening model for abortion drug, and EBs’ diameter, cell apoptosis, and differentiation changes of the germ layers can serve as criteria of abortion drug screening.
ABSTRACT
@#Objective To explore the clinical value of three-dimensional computed tomography bronchography and angiography (3D-CTBA) in robotic lung segmentectomy. Methods A non-randomized control study was performed and continuously enrolled 122 patients who underwent robotic lung segmentectomy in our hospital from January 2019 to January 2020. 3D-CTBA was performed before operations in 53 patients [a 3D-CTBA group, including 18 males, 35 females, with a median age of 52 (26-69) years] and not performed in the other 69 patients [a traditional group, including 23 males, 46 females, with a median age of 48 (30-76) years]. The clinical data of the patients were compared between the two groups. Results All the patients were successfully completed the surgery and recovered from hospital, with no perioperative death. The baseline characteristics of the patients were not significantly different between the two groups (P>0.05). No significant difference was found in the operative time [120 (70-185) min vs. 120 (45-225) min, P=0.801], blood loss [50 (20-300) mL vs. 30 (20-400) mL, P=0.778], complications rate (17.0% vs. 11.6%, P=0.162), postoperative hospital stay [7 (4-19) d vs. 7 (3-20) d, P=0.388] between the two groups. In the 3D-CTBA group, 5 (9.4%) patients did not find nodules after segmentectomy, and only 1 (1.9%) of them needed lobectomy, but in the traditional group, 8 (11.6%) patients did not find nodules and had to carry out lobectomy, the difference was statistically significant (P<0.05). The follow-up time was 10 (1-26) months, and during this period, there was no recurrence, metastasis or death in the two groups. Conclusion 3D-CTBA is helpful for accurate localization of nodules and reasonable surgical planning before operations, and reducing wrong resections in segmentectomy, without increasing the operation time, blood loss and complications. It is safe and effective in anatomical lung segmentectomy.
ABSTRACT
@#Objective To evaluate the feasibility and clinical value of robot-assisted lobectomy through anterior approach. Methods We retrospectively analyzed the clinical data of 180 patients who underwent robot-assisted lobectomy through anterior approach in our hospital between April 2017 and February 2018. There were 97 males and 83 females, aged 59.5 (32.0-83.0) years. The clinical effects were analyzed.

ABSTRACT
Objective::To investigate the distribution status of medicinal plants in the wild areas of Russian Caucasus and Altai, and clarify the types and efficacy information of medicinal plants in the area, so as to dig deep into new resources and new functions of medicinal plants in the countries along the Belt and Road. Method::Medicinal plants in the wild were searched and collected to make waxy specimens, and sent back to the country to extract the total DNA of the leaves of the leaves. Internal Transcribed Spacer(ITS)sequence universal primers were used for Polymerase Chain Reaction (PCR)amplification. The PCR products were sent for the two-way sequencing, and the sequencing results are spliced by software according to National Center for Biotechnology Information(NCBI). The same ITS sequence of the highest similarity species obtained by database BLAST was analyzed by DNAman software to identify the ITS sequence of the species and the ITS sequence of the same species. The MEGA 7 software was used as the phylogenetic tree, and the Kimura-2 parameter genetic distance was used to construct the neighbor joining(NJ) phylogenetic tree by the neighbor-joining method. The confidence of each branch of the development tree was tested by the bootstrap test method. A total of 2 000 cycles were performed, and the results were identified based on the clustering results. On this basis, the key medicinal plants in the Russian Caucasus and Altay wild areas were summarized and analyzed. Result::After BLAST alignment in NCBI database, the ITS sequences of each specimen were clustered with the login sequences on the NCBI database, which were separated from the outer group. The species classification of the specimens to be identified was determined by combining the characteristics of the specimens. A total of 51 plants were identified from the specimens collected in the field, covering 44 genera of 17 families, and 29 plants had clear efficacy records. The National Drug List of the Russian Federation and the Chinese Pharmacopoeia were retrieved to summarize commonly used medicinal plants in China and conclude that 20 kinds of Chinese and Russian common medicinal materials have different medicinal effects in local areas. This study has a reference significance for expanding the scope and clinical experience of traditional Chinese medicines, and provides a basis for strengthened local species conservation, development and utilization of wild medicinal plant resources.

Perioperative outcomes(the operation time, intraoperative blood loss, postoperative thoracic drainage volume and time, pain score, complications, postoperative hospital stay and survival and mortality) were compared.Results:All the patients successfully completed the surgery and recovered from hospital, with no perioperative death.The baseline characteristics(sex, age, clinical symptoms, smoking status, underlying disease, tumor size, pathological type) and type of segmentectomy were comparable. There was significant difference in operative time[120(interquartile range, IQR 60-225)min vs. 155( IQR 75-330)min, P<0.001], blood loss[30( IQR 20-400) ml vs. 100( IQR 20-1 600) ml, P<0.001] between the robotic and VATS groups, respectively. But there was no significant difference in postoperative thoracic drainagevolume[4( IQR 1-15) days vs. 4( IQR 2-29) days, P=0.547], postoperative thoracic time[755( IQR 200-3 980)ml vs. 815( IQR 280-3 920)ml, P=0.902], pain score[2.33( IQR 0.88-4.75) points vs. 3.13( IQR 0.95-5.29)points, P=0.199], complications[7.4%(14/190) vs. 6.3%(12/190), P=0.303], postoperative hospital stay[7( IQR 3-19) days vs. 6( IQR 4-21) days, P=0.405] , number of lymph nodes[(4.83±3.18) vs.(6.15±4.1), P=0.255] between the robotic and VATS groups, respectively. The follow-up time was 6.5( IQR 1-26) months in the two groups, without recurrence, metastasis or death. Conclusion:Robotic lung segmentectomy is safe and feasible. This approach might lead to a better in operative time and blood loss. The short-term efficacy is similar with thoracoscopy, and the long-term efficacy needs further follow-up time.
ABSTRACT
Objective:To study the feasibility of establishing gastrointestinal anastomosis by magnetic compression technique in rabbits.Methods:Ten healthy New Zealand rabbits were selected as models for gastrointestinal anastomosis by magnetic compression technique. Daughter and parent magnets suitable for gastrointestinal anastomosis in rabbits were designed and manufactured. A daughter magnet was inserted into the stomach through the purse fistula in the lack of blood vessel area of gastric body, and was pushed into the duodenum along the intestinal tract. And then a parent magnet was inserted through the stomach fistula. The daughter and parent magnets were automatically attracted and pressed the gastric and intestinal walls after they were adjusted in the proper position. The stomach fistula was closed with purse string suture. After ischemia, necrosis, detachment of the tissues between magnets, gastrointestinal anastomosis was established, and the magnets and necrotic tissues were expelled together from the body through the digestive tract. Survival of experimental animals was observed. Anastomotic specimens were obtained one month after operation. The blasting pressure of anastomotic stoma was measured, and the healing of anastomotic stoma was observed with naked eyes.Results:According to the pre-designed operative route, 10 New Zealand rabbits all successfully completed the operation and survived one month after surgery. No complications occurred during perioperative period. The operation time was 35.80±4.71 min (range 28.00-43.00 min), and the magnet discharge time was 11.40±1.56 days (range 9.00-14.00 days). Anastomotic specimens were obtained one month after the operation. Gross observation showed that the anastomotic stoma of gastrointestinal bypass anastomosis healed well, and the surrounding tissues adhered slightly. The anastomotic bursting pressure was 103.00±7.95 mmHg (range 94.00-113.00 mmHg) (1 mmHg=0.133 kPa).Conclusion:The establishment of gastrointestinal anastomosis by magnetic compression technique in rabbits is simple and effective.
ABSTRACT
Objective:To design magnets to locate colorectal neoplasms based on magnetic tracer technology, and to test its feasibility and safety by animal experiments.Methods:The magnets used for endoscopic localization of colorectal tumors consist of a tracer magnet and a pursuit magnet, both of which are ring-shaped Nd-Fe-B magnets. Eight healthy Beagle dogs were used as animal models. Tumor locations were assumed in the different parts of the colon and rectum under colonoscopy. The tracer magnet was sent to the hypothetical tumors by endoscopic soft tissue clamp and fixed near the tumors. After 24 hours, laparoscopic surgery was performed under general anesthesia. The pursuit magnet was inserted near the resected colon or rectum through the main operating hole. The tracer magnet was absorbed to the pursuit magnet to identify the location of tumors.Results:The tracer magnet and pursuit magnet were successfully designed and processed. The suction force between the tracer magnet and the pursuit magnet at zero distance was 16 N. All the 8 Beagle dogs successfully received indwelling of magnets under colonoscopy, and no magnets fell off after 24 hours. After the placement of pursuit magnet under laparoscopy, the two magnets attracted each other rapidly and accurately, and successfully completed localization of tumor site without any damage during the operation.Conclusion:Colonoscopy combined with laparoscopy for colorectal neoplasms localization based on magnetic tracer technique is simple, accurate, safe and feasible.
ABSTRACT
Objective To verify the feasibility and safety of stomach tumor marker localization based on magnetic tracer technique in dogs.Methods Six male Beagle dogs were examined by gastroscopy.Then tracer magnets were sent to the "tumor" locations assumed in advance and fixed near the "tumors" by endoscopic soft tissue clamp.Laparoscopic gastric tumor localization was performed under general anesthesia 24 hours later.The tracer magnet was placed near the tumor on the surface of the stomach through the operating hole after the conventional establishment of laparoscope puncture parallel mirror to explore the tracer magnet.After the two magnets were attracted,the location of the tracer magnet seen under the laparoscope was the location of the gastric tumor,so as to complete the labeling and positioning of the lesion.Results All the 6 Beagle dogs were successfully implanted with tracer magnets under gastroscopy.Twenty-four hours after the gastroscopy,the pursuit magnet was successfully implanted during laparoscopic surgery.The two magnets automatically attracted each other and formed a sandwich structure of "tracer magnet-gastric wall-pursuit magnet ",which completed the location and identification of gastric tumor under the laparoscopy.Conclusion Gastroscopy combined with laparoscopy based on magnetic tracer technique is simple,accurate,safe and feasible.

To explore the correlation between hematoma expansion within 24 hours of hypertensive intracerebral hemorrhage and signs on nonenhanced computed tomography(NECT). Methods The clinical data and CT images of 185 patients with hypertensive intracerebral hemorrhage were retrospectively analyzed.The differences in CT parameters were compared between the expansion group and the unexpanded group.Binary logistic regression analysis was performed on the indicators with statistical significance between the two groups to identify the potential correlation between CT parameters and hematoma expansion.The roles of blend sign,lobulation sign,and black hole sign in predicting early hematoma expansion were assessed. Results The CT quantitative data including initial volume,maximum diameter,minimum diameter,maximum CT value,mean CT value,difference between maximum diameter and minimum diameter showed no significant difference between these two group(all >0.05).CT qualitative data including blend sign,lobulation sign,and black hole sign were significantly different(<0.05)but the differences became not significant after the hematoma broke into the ventricles.Binary logistic regression analysis showed that blend sign,lobulation sign,and black hole sign were independent risk factors for early hematoma expansion,with sensitivity,specificity,positive predictive value,and negative predictive value of the combined signs and the early hematoma expansion calculated by the four-fold table method being 78.4%,59.0%,42.1%,and 87.8%,respectively,and the Youden index was 0.374.Its Youden index was closer to 1 than the blend sign,the black hole sign,and the lobulation sign. Conclusion The blend sign,lobulation sign,and black hole sign in NECT can be used to predict hematoma expansion within 24 hours after hypertensive cerebral hemorrhage.

Objective To explore the clinical significance regarding monitoring circulating tumor cells in early stage lung adenocarcinoma.Methods From November 2015 to January 2018,48 patients with stage Ⅰ lung adenocarcinoma were included in the study.BCAR1 expression in CTCs in peripheral blood were detected by using CanPatrolTM and RNA in situ hybridization detection.Results Among the 48 cases,CTCs and BCAR1 (+)-CTCs were detected in 41 cases(85.4％) and 30 cases(62.5％),respectively.Number of BCAR1 (+)-CTCs seemed to be significantly positively related to that of CTCs.BCAR1 (+)-CTCs were more likely to appear in the M-CTCS and E&M-CTCS.BCAR1 (+)-CTCs remarkably increased in three relapsed cases.Furthermore,there were 19 stable cases who had postoperative CTCs data:(1) in 12 patients,either CTCs or BCAR1 (+)-CTCs were significantly reduced or remained stable;(2) in 7 cases,CTCs increased,but BCAR1 (+)-CTCs remained stable in 2 cases,reduced in 1 case,and the other 4 cases underwent close follow-up.Conclusion Evaluation of BCAR1 (+)-CTCs possibly can be contributive to prediction of early lung adenocarcinoma recurrence or metastasis.
ABSTRACT
Clinical data of one patient with sepsis-induced myopathy (SIM) who was successfully treated were reviewed retrospectively, analysis was conducted combined with the relevant literatures. Patient was a middle-aged woman without underlying disease, she was admitted to hospital because of fever, cough, chest tightness and shortness of breath, during the treatment period, type II respiratory failure occurred repeatedly, and it was difficult in withdrawing respirator, patient was finally diagnosed with SIM. After anti-infective treatment and rehabilitation training, she was successfully withdrawn respirator, muscle strength was recovered. This case suggests that SIM can be completely cured through early identification, neuromuscular nutrition therapy, graded rehabilitation training and lung rehabilitation therapy.
ABSTRACT
OBJECTIVE: Explore the clinical benefit factors of progression-free survival(PFS) in sensitive epithelial growth factor receptor(EGFR) gene mutated advanced non-small cell lung cancer patients treated with first-generation of EGFR tyrosine kinase inhibitor(TKI).METHODS: The clinical data of 166 patients who received first-line treatment with first-generation EGFR-TKI were retrospectively collected in 2016-2017 from Xiangya Hospital, Central South University. The patients were divided into three groups: PFS≤3 m,3 m
