Objective:To evaluate the role of a single PET-CT scan in predicting survival and prognosis in patients with non-small cell lung cancer (NSCLC) who did not undergo surgery but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy.Methods:A retrospective analysis was conducted on the data of 23 NSCLC patients treated at the Cancer Hospital of the Chinese Academy of Medical Sciences from May 2022 to June 2024. All patients were pathologically confirmed, received neoadjuvant chemotherapy combined with immunotherapy, did not undergo surgery for various reasons, and instead received radiotherapy. Each patient underwent only one PET-CT scan after neoadjuvant chemotherapy combined with immunotherapy and before radiotherapy. According to the maximum standardized uptake value (SUV max) on PET-CT, patients were divided into the low-uptake group (SUV max < 8, n=12) and high-uptake group (SUV max ≥ 8, n=11). Survival analysis was performed using the Kaplan-Meier method with survival curves plotted. Univariate analysis of influencing factors of survival was conducted using the Cox proportional hazards regression model. Clinical characteristics and survival outcomes of the two groups were compared, including progression-free survival (PFS) and overall survival (OS). Results:The 1-year PFS rates were 100% in the low-uptake group, 54.5% in the high-uptake group. This difference was statistically significant ( P=0.007). The 1-year and 2-year OS rates were both 100% in the low-uptake group, the 1-year and 2-year OS rates were both 90.9% in the high-uptake group, with no statistically significant difference ( P=0.394). Univariate Cox analysis identified age as an independent factor affecting PFS. Conclusions:For NSCLC patients who did not undergo surgical resection but received radiotherapy after neoadjuvant chemotherapy combined with immunotherapy, a single PET-CT scan before radiotherapy has potential value in predicting PFS. However, clinical studies with larger sample size and longer follow-up are required to evaluate its predictive value for OS.

ObjectiveIn the treatment of acute gouty arthritis （AGA）， western medicine is mostly used for anti-inflammatory and analgesic purposes to control the blood uric acid level， but some patients are still at risk of poor control and recurrent attacks. Chinese medicinal prescriptions， potent in resisting inflammation and relieving pain， are able to stabilize the blood uric acid level， reduce acute attacks， and improve the clinical efficacy of western medicine. However， there is a lack of evidence to support their use as evidence-based medicine. This study employed network Meta-analysis （NMA） to evaluate the efficacy and safety of common Chinese medicinal prescriptions in the treatment of AGA， aiming to provide evidence-based medical evidence for the clinical use of Chinese medicinal prescriptions in the treatment of AGA. MethodChinese and English databases were searched for prospective cohort studies and randomized controlled trials （RCTs） on Chinese medicinal prescriptions against AGA from database inception to December 1， 2022. Stata software and Review Manager were used for statistical analysis. ResultForty-four papers with 3 564 cases involved were included in the current NMA. In terms of reducing blood uric acid， the cumulative probability results showed that Mahuang Lianyao Chixiaodou Tang showed optimal efficacy （87.60%）. In terms of relieving joint pain， Danggui Niantongtang and Guizhi Shaoyao Zhimutang showed optimal efficacy （92.00% and 82.30%）. In terms of improving erythrocyte sedimentation rate （ESR）， Simiaowan was superior to other prescriptions （87.00%）. In terms of reducing C-reactive protein （CRP）， Simiaowan and Baihutang modified with Guizhitang showed superior efficacy （76.00% and 66.10%）. In terms of safety， except for the basic treatment group， Mahuang Lianyao Chixiaodou Tang had the lowest probability of adverse events， and Danggui Niantongtang had the highest probability of adverse reactions during treatment. According to the results of cluster analysis， Mahuang Lianyao Chixiaodou Tang and Simiaowan are effective and safe. ConclusionAccording to the results of NMA， Chinese medicinal prescriptions can assist in the treatment of AGA and improve the effectiveness of western medicine. For patients with AGA， clinicians can choose Mahuang Lianyao Chixiaodou Tang or Simiaowan as an auxiliary drug for routine western medicine treatment.

Objective:To evaluate the value of chemoradiotherapy and surgery in cervical esophageal cancer (CEC).Methods:Data of 459 patients with CEC from 2004 to 2017 were collected and retrospectively analyzed from the surveillance, epidemiology, and end results (SEER) database of National Cancer Institute (US). All patients were divided into the chemoradiotherapy group ( n=379) and surgery group ( n=80) according to the treatment methods. Survival analysis was performed by Kaplan-Meier method and survival curve was drawn. Multivariate survival analysis was conducted by Cox proportional hazards regression model. The death rate of different causes between two groups was calculated by cumulative incidence function (CIF). The differences of death rate between two groups were evaluated by Fine-Gray competing risk model. By analyzing the clinical characteristics and survival of CEC patients, the overall survival (OS) was compared between the surgery and chemoradiotherapy groups. Results:The 2- and 5-year survival rates in the chemoradiotherapy group were 43.1% and 22.4%, while those of the surgical group were 46.8% and 26.0%, respectively. No significant difference was observed in the OS between the chemoradiotherapy and surgery groups ( P=0.750). Cox multivariate analysis showed that treatment (surgery group vs. chemoradiotherapy group) was not an independent prognostic factor for OS. Based on the results of competing risk analysis, the risk of esophageal cancer-specific death in the chemoradiotherapy group was higher than that in the surgery group, and the difference was statistically significant between two groups ( P<0.001). The risk of other cause-specific death in the chemoradiotherapy group was lower than that in the surgery group ( P<0.001). The proportion of patients who died of oral, oropharyngeal, hypopharyngeal and laryngeal diseases in the surgery group was significantly higher than that in the chemoradiotherapy group(all P<0.001). Conclusions:No significant difference is observed in the OS of CEC patients treated with chemoradiotherapy or surgery. In the surgery group, the risk of esophageal cancer-specific death is lower, whereas the risk of other cause-specific death is higher compared with those in the chemoradiotherapy group.

Objective:To investigate the efficacy and safety of laparoscopic partial nephrectomy in the treatment of renal tumors with renal score of 10.Methods:From February 2016 to March 2021, 23 patients who underwent laparoscopic partial nephrectomy in Peking University Third Hospital with renal tumors of R. E.N.A.L. score of 10 was studied retrospectively, including 16 cases of male and 7 cases of female, with 11 cases on the right side and 12 cases on the left side. The patients’ age was (55.0±16.4) years, and BMI was (25.4±3.6) kg/m 2. The maximum diameter of the tumor was (3.5±1.4)cm. Laparoscopic partial nephrectomy was performed after complete examination. The observation indexes included operation time, blocking time, complications, postoperative hospital stay and the trifecta (negative surgical margin, blocking time ≤25 minutes, and no perioperative complications). Results:All operations were successfully completed, only 4 cases were converted to open surgery. The median operation time was 153 min(99-346 min). The median blocking time was 27 min(14-60min). The median postoperative hospital stay was 6 d(4-11 d). Postoperative complications occurred in 7 cases(fever in 5 cases, intestinal obstruction in 1 case, postoperative blood transfusion and leg intermuscular venous thrombosis in 1 case). 9 cases (39.1%) achieved the trifecta. 19 cases who completed by laparoscopy, their operation time was 151 min(99-303 min), blocking time was 28 min(18-60 min), postoperative hospital stay was 6 d(4-11 d), fever occurred in 4 cases, and 6 cases achieved the trifecta (31.6%). The follow-up time was 3-62 months, with a median of 32 months, and there was no recurrence or metastasis.Conclusions:Laparoscopic partial nephrectomy is safe and effective in the treatment of renal tumors with renal score of 10.Although the tumor is highly complex, it also achieves the purpose of preserving nephron to the greatest extent. If technical conditions permit, laparoscopic partial nephrectomy could be considered for the treatment of highly complex renal tumors.

Objective: To compare the detection rate of herpes virus and enterovirus (EV) in paired cerebrospinal fluid and serum samples of patients with viral encephalitis. Methods: A total of 109 paired cerebrospinal fluid and serum specimens were collected from patients who were clinically diagnosed with suspected viral meningitis in Children′s Hospital of Hunan from December 2017 to February 2018. One-step nested real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and real-time fluorescence quantitative PCR were used to detect enterovirus and herpes virus respectively and the detection rates of different virus and sample types were analyzed. SPSS 17.0 was used for statistical analysis of the test result . Results: Among the 109 pairs of specimens, the positive rates of human herpes virus type 6 (HHV6), herpes simplex virus-1 (HSV1), Epstein-Barr virus (EBV), cytomegalovirus (CMV) and enterovirus group A type 71(EV-A71) in serum were 7.34%, 4.59%, 7.34%, 9.17% and 10.09%, respectively, and in cerebrospinal fluid were 5.50%, 2.75%, 0, 5.50%, and 6.42%, respectively. The result showed that there were statistically significant differences between the two types of specimens for herpes virus and enterovirus (P<0.05). In cerebrospinal fluid and serum samples, the longest time for EV-A71 positive detection was 2 and 7 days after onset, respectively; the longest time for CMV positive detection was 3 and 26 days after onset, respectively; the longest time for HHV6 positive detection was 7 and 8 days after onset, respectively; the longest time for HSV1 positive detection was both 12 days after the onset; in serum samples, the longest time for EBV positive detection was10 days after onset, but in cerebrospinal fluid, no EBV was detected within 10 days of onset. Conclusions EV-A71 is the most prevalent pathogen causing viral encephalitis in hunan, the overall positive rate of virus in serum samples was higher than that in cerebrospinal fluid samples. Virus stays longer in serum than in cerebrospinal fluid. It is suggested that the time is of great significance for the pathogen detection of children with viral encephalitis, the specimen type can be selected reasonably according to the time of onset.

Objective To explore the relationship between G-protein β3 subunit (GNB3) gene C825T polymor?phism and the weight gain of schizophrenics treated with olanzapine. Methods Ninety schizophrenics of first time hospi?talization were collected and treated with olanzapine for 12 weeks. The changes of body weight and body mass index (BMI) were detected before and after 12-week olanzapine treatment. The GNB3 gene C825T polymorphism in patients was determined by polymerase chain reaction (PCR) and DNA sequencing technique. The correlation of GNB3 gene C825T polymorphism and change of clinical parameters was analyzed. Results Body weight and BMI in patients were all increased significantly after treatment (all P<0.01). Weight gain rate (WGR) and increase of BMI in the TT genotype group were higher than those in the CC genotype group (all P<0.01). WGR and increase of BMI in the T-allele carrier (TT and CT genotypes) were higher than those in the T-allele non-carrier (CC genotype) (all P<0.01). There was signifi?cant difference in distribution of genotypes between WGR ≥7% group (CC 15.69%, CT 54.90%, TT 29.41%) and WGR <7% group (CC 38.46%, CT 43.59%, TT 17.95%) (P<0.05). The frequency of T-allele in the WGR≥7% group (63.33%) was higher than that in the WGR<7%group (39.74%) (P<0.05). Multi-variable linear regression indicated that TT genotype (contrasted with CC genotype) was an influential factor for change of body weight after treatment with olan?zapine (β=1.83, standardized β=0.29, P<0.01). Conclusions The GNB3 gene C825T polymorphism is associated with olanzapine-induced weight gain.

Objective To evaluate the reliability and accuracy of three-dimensional digital fusion anatomy in the preoperative evaluation and therapeutic strategy choice of intracranial tumors.Methods MRI scan,including regular MRI,MRA,MRV and DTI,were performed in 87 case.Then tumor themselves as well as tumor-associated structures were reconstructed and fused through iPlan 2.6 software.Based on the reconstructed images,therapeutic strategy were established,preoperative and intraoperative imags were compared.Results The digital reconstruction were successfully finished in all cases.Meanwhile,digital images,originally radiological images and actual images matched well.No approach-associated complication were met in our series.Among tumors in the convexity,the relationship of the reflux veins and the tumors were divided into three types:anterior(12 cases),posterior(19 cases) and overriding(3 cases).All of the relationships were seen in the preoperative fusion image,and the veins were all effectively protected during operation.The tumor-associated arteries could be pushed or wraped by the tumors,and the three-dimensional fusion image could provided their virtually aberrant pathway as well as their relationship with tumor.During microsurgical managment of tumors in the deep brain parenchyma,safe approach were found with the help of comprehensive understanding of the tumors and their adjacent structures.Conclusion Three-dimensional digital fusion anatomy can vividly and accurately display full rang of information about the tumor,and facilitate tumor treatment safely.
