Ovarian cancer is one of the most common gynecologic cancers in the world.Over the past few decades,there has been considerable research reporting on the mechanisms of cancer development and progression,with multiple nerve as well as neurotransmitters involved.Nerve innervation is also found in ovarian cancer.And in ovarian cancer,various nerves and neurotransmitters play different roles.They are involved in ovarian cancer cells'proliferation metastasis,apoptosis and changes in the tumor microenvironment.Further understanding of the role of these nerve endings in the development of ovarian cancer is essential for understanding the mechanisms of cancer progression.This will be important for subsequent research focusing on tumor regulation.While glucocorticoids and sympathetic nerve-released norepinephrine are able to promote ovarian cancer progression,serotonin may inhibit cancer cell growth.Also,parasympathetic and sensory nerves are capable of having either a positive or negative effect on ovarian tumors.These relevant studies offer the possibility of new therapeutic options for oncology,it may be possible to mitigate the progression of cancer with inexpensive receptor inhibitors or agonists.This will facilitate the subsequent exploration of therapeutic possibilities forovarian cancer and other cancer-related treatments.In this review,we also present some insights into the role of the nervous system in the regulation of ovarian cancer,which we hope will provide new insights into the innervation and progression of ovarian cancer.

Objective: To explore the risk intensity and related influencing factors of post-traumatic stress disorder (PTSD) among high-stress rescue workers, and to provide effective tools for the risk assessment of PTSD in military rescue workers. Method: From June to August 2022, cluster sampling was used to select the high-stress rescue personnel of an Army department as the survey subjects. The acute Stress reaction (ASD) scale and PTSD checklist were used to evaluate the risk of PTSD in military rescue personnel. Multivariate logistic regression were used to analyze the influencing factors of PTSD. Results: The age of 4 460 subjects was (24.38±4.072) years old, including 4 396 males (98.6%). The positive rate of initial screening for ASD was 2.85% (127/4 460). The positive rate of PTSD was 0.67% (30/4 460). Multivariate logistic regression model analysis showed that female, older age, recent trauma exposure history, passive smoking and alcohol consumption were at higher risk of ASD, the values of OR (95%CI) were 4.183 (1.819-9.618), 6.278 (1.363-28.912), 3.094 (1.500-6.379), 2.059 (1.298-3.267) and 2.607 (1.614-4.211), respectively; Lower education level was associated with lower risk of ASD, OR (95%CI) was 0.593 (0.359-0.978); People who are older, thinner, have a history of mental illness, and drink alcohol were at higher risk for PTSD, the values of OR (95%CI) were 20.144 (2.459-165.043), 10.287 (2.218-47.700), 91.104 (8.592-965.980) and 2.866 (1.144-7.180), respectively. Conclusion: Gender, age, education level, passive smoking, alcohol consumption, past history of mental illness and body mass index may be related to the potential risk of PTSD in rescue workers,passive smoking, alcohol consumption, and weight controlling should be focused on to reduce potential risks of PTSD.

Objective: To examine the safety and effectiveness of laparoscopic individualized surgical treatment for chronic traumatic diaphragmatic hernia (CTDH). Methods: The clinical data and follow-up data of 29 CTDH cases admitted to the Qilu Hospital of Shandong University or the First Affiliated Hospital of Shandong First Medical University from June 2015 to January 2023 were retrospectively analyzed. There were 21 males and 8 females, aged (49.4±17.8) years (range: 19 to 79 years). The main clinical manifestations were symptoms of the digestive system and respiratory system, and only 4 cases were asymptomatic. All patients received laparoscopic treatment (conversion to open surgery was not excluded). Intraoperative exploration (location of the hernia, contents of the hernia, diameter of the hernia ring), surgical conditions (surgical repair plan, operation time, blood loss, postoperative complications) and postoperative follow-up were analyzed and discussed. Results: Laparoscopic repair was successfully completed in 27 cases, including simple suture in 6 cases, suture and patch repair in 17 cases, the anterior abdominal wall muscle flap reversal suture and patch repair of in 3 cases, and patch bridge repair in 1 case. The operation time was (112.8±44.7) minutes (range: 60 to 200 minutes). The amount of bleeding (M(IQR)) was 35 (58) ml (range: 10 to 300 ml). The other 2 patients were converted to laparotomy. Except for one patient with transverse colon strangulation necrosis who died of aggravated pulmonary infection after surgery, the remaining 28 patients were discharged successfully. The follow-up time was 36 (24) months (range: 1 to 60 months). During the follow-up period, only two patients had occasional left upper abdominal discomfort. Twenty-seven patients with left diaphragmatic hernia had no recurrence, and the symptoms of 1 patient with right diaphragmatic hernia were relieved. Conclusion: Customized laparoscopic surgical repair for CTDH according to the location and size of the diaphragmatic defect can achieve good surgical results.

OBJECTIVES:
To investigate the prevalence of diabetes mellitus (DM) among Uygur children in Hotan Prefecture of Xinjiang, China, as well as the factors influencing the development of DM.
METHODS:
The cluster random sampling method was used to select 5 308 children, aged 4-18 years, from the middle and primary schools and kindergartens in Hotan Prefecture of Xinjiang. The survey methods included questionnaire survey and the measurement of height and weight. All subjects were tested for fasting fingertip blood glucose to investigate the prevalence of DM and impaired fasting glucose (IFG).
RESULTS:
A total of 5 184 valid questionnaires were collected. Fourteen children (0.27%) were found to have DM, among whom 8 had type 1 DM, 2 had type 2 DM, and 4 had unclassified DM. Twenty-nine children (0.56%) were found to have IFG. There was no significant difference in the prevalence rate of DM and IFG between boys and girls (P>0.05). The prevalence rate of DM was 0.18% in the 4-<10 years group, 0.47% in the 10-<15 years group, and 0.07% in the 15-18 years group (P=0.072).The prevalence rate of IFG in the above three age groups was 0.18%, 0.94%, and 0.42%, respectively, with a significant difference among groups (P=0.007). The proportion of family history of DM and the proportion of overweight/obesity in children with DM were significantly higher than those in children without DM (P<0.05), while the proportion of children with DM who preferred coarse grains was significantly lower than that in children without DM (P<0.05).
CONCLUSIONS
The prevalence of DM and IFG in Uyghur children in Hotan Prefecture of Xinjiang is relatively low. There is no significant difference in the prevalence of DM among children of different genders or age groups, but the prevalence of IFG in children of different age groups is different. A family history of DM, overweight or obesity, and low intake of coarse grains might be associated with the development of DM.

OBJECTIVE:
To evaluate the effect of sonication, repeated freeze-thaw cycles, calcium salt solution and their combination on the content of related growth factors (GFs) released by platelet rich plasma (PRP).
METHODS:
Twenty PRPs from healthy blood donors were divided into 9 groups, including sonication group, freeze-thaw group, calcium gluconate group, calcium chloride group, sonication + calcium gluconate group, sonication + calcium chloride group, freeze-thaw + calcium gluconate group, freeze-thaw + calcium chloride group, and sonication + freeze-thaw group. After PRP activated by above 9 methods, the content of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and platelet-derived growth factor-BB (PDGF-BB) were detected by ELISA.
RESULTS:
The platelet concentration of the samples was (966.7±202.6)×109/L. The content of TGF-β1 in sonication + freeze-thaw group was the highest, while the lowest was in freeze-thaw group. The content of VEGF in freeze-thaw + calcium chloride group was the highest, while the lowest was in calcium gluconate group. The content of PDGF-BB in sonication + freeze-thaw group was the highest, while the lowest was in calcium gluconate group. There was no significant differences in the three GFs between calcium gluconate group and calcium chloride group.
CONCLUSION
Among the 9 activated methods of PRP, there is no difference between two calcium salt solutions. And the combination of repeated freeze-thaw cycles and sonication may be the best treatment method to promote PRP to release GFs, while calcium gluconate is the weakest way.

Journal of Peking University(Health Sciences) 2021;53(2):332-336
OBJECTIVE:
To explore the technical details and short-term effects of radiofrequency obliteration of varicose veins of lower extremities guided by combined venography and ultrasound.
METHODS:
Thirty-seven patients with varicose veins of lower extremities were treated with radiofrequency obliteration using Olympus Celon RFiTT® under combined guidance of venography and ultrasound. The indications included varicose veins of lower extremities and reflux of the great saphenous vein confirmed by ultrasound. The contraindications included deep vein thrombosis, cardiac pacemaker, severe cardio- and cerebrovascular diseases or coagulation disorders. Under ultrasound guidance, the saphenous vein around knee level was punctured using a 21G needle, and a 7F sheath was introduced. Through the sheath a venography was made, and an Olympus Celon ProCurve radiofrequency catheter was inserted and advanced to the great saphenous vein under road map, and the catheter tip was positioned at the point 2 cm below the sapheno-femoral junction. The swelling anesthesia was made under ultrasound guidance. Then the radiofrequency obliteration was performed with pressing of the treatment section. The venography was repeated to ensure optimal outcomes. If necessary the radiofrequency obliteration could be repeated once to twice. After that the superficial varicose veins were stripping by small incisions under local anesthesia. After operation, medical decompression stocking was utilized immediately and sustained for three months. The clinical data, intraoperative radiation dose, exposure time and short-term effects were retrospectively analyzed.
RESULTS:
After the operation, all the patients walked out of the operating room by themselves. The success rate of operation was 100%. The intraoperative radiation dose was 1.78-10.12 mGy (mean 6.56 mGy), and the exposure time was 61-448 s (mean 161 s). By 3 months follow-up, the symptoms were alleviated in all the 37 patients, and the occlusion rate was 100%. No complications such as skin burns, ecchymosis and deep venous thrombosis were found.
CONCLUSION
The short-term effects of radiofrequency obliteration using Olympus Celon RFiTT® system in a manner of twice fixed point followed by once reciprocating radiofrequency were satisfactory. Radiofrequency obliteration of great saphenous veins guided by venography and ultrasound has not only the advantages of minimal trauma and rapid recovery, but also the advantages of accurate location, exact effect and avoidance of complications.

BACKGROUND:
Accurate estimation of the glomerular filtration rate (GFR) and staging of chronic kidney disease (CKD) are important. Currently, there is no research on the differences in several estimated GFR equations for staging CKD in a large sample of centenarians. Thus, this study aimed to investigate the differences in CKD staging with the most commonly used equations and to analyze sources of discrepancy.
METHODS:
A total of 966 centenarians were enrolled in this study from June 2014 to December 2016 in Hainan province, China. The GFR with the Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Berlin Initiative Study 1 (BIS1) equations were estimated. Agreement between these equations was investigated with the κ statistic and Bland-Altman plots. Sources of discrepancy were investigated by partial correlation analysis.
RESULTS:
The κ values of the MDRD and CKD-EPI equations, MDRD and BIS1 equations, and CKD-EPI and BIS1 equations were 0.610, 0.253, and 0.381, respectively. Serum creatinine (Scr) explained 10.96%, 41.60% and 17.06% of the variability in these three comparisons, respectively. Serum uric acid (SUA) explained 3.65% and 5.43% of the variability in the first 2 comparisons, respectively. Gender was associated with significant differences in these 3 comparisons (P < 0.001).
CONCLUSIONS
The strengths of agreement between the MDRD and CKD-EPI equations were substantial, but those between the MDRD and BIS1 equations and the CKD-EPI and BIS1 equations were fair. The difference in CKD staging of the first 2 comparisons strongly depended on Scr, SUA and gender, and that of CKD-EPI and BIS1 equations strongly depended on Scr and gender. The incidence at various stages of CKD staging was quite different. Thus, a new equation that is more suitable for the elderly needs to be built in the future.
