[Application of uniportal video-assisted thoracoscopic surgery in the treatment of tuberculous destroyed lung].

Objective: To examine the efficacy of uniportal video-assisted thoracoscopic surgery in the treatment of tuberculous destroyed lung. Methods: This is a retrospective case series study. The clinical data of 33 patients with tuberculous destroyed lung who had received uniportal video-assisted thoracoscopic pulmonary resection from June 2020 to May 2022 in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed. There were 13 males and 20 females, aged (47.5±16.2) years (range: 19 to 68 years). The course of the disease was from 15 days to 8 years. All 33 cases had pleural adhesions, including 30 cases with total pleural adhesions and atresia. There were 21 cases of calcification of the thoracic lymph node, 17 cases of aspergillus infection, 4 cases of drug-resistant tuberculosis. The surgical incision was located at the midline of the fifth intercostal axilla, length 4 to 5 cm. The principle of separating pleural adhesions was easy first and difficult later, and then appropriate procedures were selected to resect the diseased lung based on the exploration situation. There were 12 cases that underwent superior lobectomy, 11 cases that underwent superior lobectomy and dorsal segmentectomy, 3 cases that underwent inferior lobectomy, 3 cases that underwent pneumonectomy, 2 cases that underwent middle and inferior lobectomy, and 1 case that underwent superior lobectomy, dorsal segmentectomy and basal segment wedgectomy. The surgical techniques, perioperative evaluation and treatment, management of complications, and the outcome were summarized. Results: Six cases were converted to thoracoscope assisted small incision or thoracotomy. For 27 cases who successfully underwent uniportal VATS, the operation time was (238.7±76.8) minutes (range: 60 to 420 minutes), the intraoperative bleeding was (400.4±315.9) ml (range: 50 to 1 200 ml). The duration of postoperative drainage was (12.7±8.3) days (range: 3 to 42 days). The postoperative hospital stay was (15.2±7.9) days (range: 6 to 43 days). Persistent postoperative pulmonary leakage occurred in 12 cases. There were 2 cases of active thoracic bleeding, one of which was cured with conservative treatment. The other case underwent secondary operation. One case of bronchopleural fistula was cured after continuous thoracic drainage to control infection and implantation of one-way bronchial valve through a fiberoptic bronchoscope. Conclusion: For selected patients with tuberculous destroyed lung, choosing the reasonable surgical procedures and techniques, the uniportal VATS could reduce surgical trauma.

[Chest hemorrhage after left total pulmonary resection for secondary rifampin-resistant tuberculosis:a case report].

The patient had received five courses of anti-tuberculosis treatment for recurrent tuberculosis. The drug sensitivity test results of the first three courses showed drug-sensitive pulmonary tuberculosis, and the fourth diagnosis was rifampin-resistant tuberculosis (RR-TB), complicated by chronic obstructive pulmonary disease, type Ⅱ respiratory failure, pulmonary heart disease, and heart failure (grade Ⅲ). The patient stopped taking the anti-tuberculosis drugs on his own in the eighth month of receiving the resistant treatment. After admission, the symptoms improved temporarily after receiving oxygen therapy, anti-infection, and anti-tuberculosis treatment. Because of hemoptysis, the patient underwent arterial embolization by catheterization, but a large amount of hemoptysis occurred shortly thereafter. Emergency left total lung resection and gauze packing for hemostasis were performed. After surgery, the patient's vital signs were maintained with mechanical ventilation and vasopressors. Forty-eight hours after surgery, the gauze was removed, and the patient underwent tracheotomy, enteral nutrition, and anti-tuberculosis treatment. After discharge, the patient underwent rehabilitative exercise and anti-resistant tuberculosis therapy. The patient's condition remained stable for more than six months of follow-up.

[Evaluation of uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculous empyema].

Objective: To examine the safety and efficacy of the uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculosis empyema. Methods: From January 2018 to December 2020, 122 cases of tuberculous empyema treated by decortication in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed, including 100 males and 22 females, aged(M(IQR)) 29.5(28.0) years (range: 13 to 70 years). According to the surgical approach and drug resistance, patients with drug-resistant tuberculosis who underwent uniportal video-assisted thoracoscopic decortication were included in group A (n=22), and those who underwent thoracotomy decortication were included in group B (n=28). Drug-sensitive patients who underwent uniportal video-assisted thoracoscopic decortication were included in group C (n=72). There was no statistical difference in the baseline data of the three groups (P>0.05). The operation, early postoperative recovery, and prognosis-related indicators were compared among three groups by Kruskal-Wallis test and χ2 test by Mann-Whitney U test and Bonferroni method between groups A and B, groups A and C. Results: The intraoperative blood loss of group A, group B, and group C was 200(475) ml, 300(200) ml, and 225(300) ml, respectively. There was no significant difference in intraoperative hemorrhage (H=2.74, P=0.254) and treatment outcome (χ2=4.76, P=0.575) among the three groups. Compared with group B, the operation time of group A (302.5(187.5) minutes vs. 200.0(60.0) minutes, U=171.0, P=0.007) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0 (2.2) months, U=146.5, P=0.032) were longer, and the postoperative drainage duration (9.5(7.8) days vs. 13.0(10.0) days, U=410.0, P=0.044), and the postoperative hospitalization time (12.0(7.8) days vs. 14.5(4.8) days, U=462.2, P=0.020) were shorter. There was no significant difference in complications between group A and group B (63.6%(14/22) vs. 71.4%(20/28), χ2=0.34, P=0.558). Compared with group C, the postoperative drainage duration of group A (9.5(7.8) days vs. 7.0(4.0) days, U=543.5, P=0.031), the postoperative hospitalization time (12.0(7.8) days vs. 9.0(4.0) days, U=533.0, P=0.031) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0(2.0) months, U=961.5, P=0.001) were longer. The operation time (302.5(187.5) minutes vs. 242.5(188.8) minutes, U=670.5, P=0.278), and complications (63.6%(14/22) vs. 40.3%(29/72), χ2=3.70, P=0.054) were not different between group A and group C. Conclusions: For drug-resistant tuberculous empyema, the uniportal video-assisted thoracoscopic decortication can achieve the same good therapeutic effect as drug-sensitive tuberculous empyema, and it is as safe as thoracotomy. At the same time, it has the advantage of minimally invasive and can accelerate the early postoperative recovery of patients.

Local anesthesia with sedation and general anesthesia for the treatment of chronic subdural hematoma: a systematic review and meta-analysis.

OBJECTIVE: Drilling and drainage is the main treatment for chronic subdural hematoma (cSDH). However, anesthesia methods also have an important effect on patients' postoperative outcomes. The clinical effect of drainage of cSDH under local anesthesia with sedation (LAS) and general anesthesia (GA) was systematically evaluated. MATERIALS AND METHODS: A literature study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for studies that compare LAS and GA for cSDH. The following treatment outcomes were compared between LAS and GA: total duration of surgery, postoperative complications, mortality, recurrence rate, and hospital length of stay (LOS). RESULTS: Four papers (n = 391, LAS: 196, GA: 195) met the inclusion criteria. Although there was no statistically significant difference between the two groups in mortality (OR: 0.47, 95% CI: 0.06-3.84, p = 0.48; p = 0.2, I2 = 39%), recurrence rate (OR: 0.82, 95% CI: 0.33-2.04, p = 0.66; p = 0.69, I2 = 0%), LOS (ratio of means: 0.86, 95% CI: 0.71-1.05, p = 0.14; p = 0.02, I2 = 75%). The total duration of surgery (MD: -26.71 min, 95% CI: -37.29 to -16.13, p < 0.00001; p = 0.65, I2 = 0%) was significantly shorter and the number of postoperative complications was significantly lower in the LAS group compared with the GA group (OR: 0.25, 95% CI: 0.13-0.50, p < 0.0001; p= 0.62, I2 = 0%). CONCLUSIONS: A systematic review and meta-analysis of the existing literature showed that LAS reduces the total duration of surgery and postoperative complications compared to GA. No significant difference in mortality, recurrence rate, and LOS was observed between the two groups.

[Investigation of occupational noise exposure and hearing loss among automobile manufacturing workers].

Objective: To investigation the situation of occupational noise exposure and hearing loss among workers in automobile manufacturing enterprise during 2017-2019 in Wuhan. Methods: Workers in automobile manufacturing who underwent physical examination in Wuhan Hospital for the Prevention and Treatment of Occupational Diseases from 2017 to 2019 were included as subjects in the cross-sectional survey. Questionnaire survey, noise detection and pure tone threshold test were used. Excluding individuals with working time less than 3 years and information deficiency, 3 948 individuals were finally included in the study. Results: Among 3 948 workers, 128 workers had hearing loss and the rate of hearing loss was 3.24%, among which 101 workers had high-frequency hearing loss and 27 workers were diagnosed as occupational noise deafness. The prevalence of hearing loss among workers previously exposed to noise was significantly higher than that without prior exposure (12.10%, 0.96%, P<0.05) . The prevalence of hearing loss among workers with occupational noise exposure <80 dB (A) , 80~<85 dB (A) and ≥85 dB (A) was 1.83%, 2.69% and 5.09%, respectively. The prevalence of high frequency hearing loss was 1.60%, 2.05% and 3.71%, respectively. The prevalence of occupational noise deafness was 0.23%, 0.64% and 1.38%, respectively. The prevalence of hearing loss and high frequency hearing loss among workers exposed to different occupational noise was statistically significant (P<0.05) , while the prevalence of occupational noise deafness was not statistically significant (P>0.05) . There were statistically significant differences in the prevalence of hearing loss (2.88%, 4.45%) and occupational noise deafness (0.46%, 1.41%) between those who used protective equipment and those who did not (P<0.05) . Compared with workers exposed to occupational noise <80 dB (A) , workers exposed to occupational noise ≥85 dB (A) had A 3.16-fold increased risk of hearing loss (OR=3.16, 95%CI: 1.44~6.95, P<0.05) . Compared to workers using hearing protective equipment, the risk of hearing loss (OR=1.96, 95%CI: 1.25~3.06, P<0.05) and occupational noise deafness (OR=3.46, 95%CI: 1.51-7.96, P<0.05) significantly increased among those without using hearing protective equipment. Conclusion: The risk of hearing loss in automobile manufacturing workers is significantly associated with occupational noise exposure and the use of hearing protective equipment. Good hearing protection may reduce the risk of occupational noise-induced hearing loss and occupational noise deafness.

[Study on the association between occupational noise exposure and cardiovascular diseases].

Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

[CD20-positive T cell lymphoma: clinicopathological features of five cases].

Objective: To investigate the clinicopathological characteristics of the T cell lymphomas with CD20 expression, and to better understand this rare entity. Methods: Two-hundred cases of T-cell lymphoma diagnosed in the Department of Pathology of the Affiliated Hospital of Qingdao University from November 2016 to February 2020 were examined, and 5 cases of CD20-positive T-cell lymphomas were identified and included. Combined with clinical data and review of the literature, the clinicopathological characteristics of the disease were analyzed. Results: The five patients were all male, and had an average age of 56 years (range, 47 to 64 years). There were 2 cases of monomorphic epitheliotropic intestinal T-cell lymphoma, 2 cases of mycosis fungoides (1 case was plaque stage and the other was tumor stage) and 1 case of indolent T-cell lymphoproliferative disorder of the gastrointestinal tract. Immunohistochemistry showed that all 5 cases expressed multiple T cell markers (CD3/CD4/CD5/CD7/CD8) and only one of B cell markers (CD20). Three of the 5 cases were negative for CD20 at the first diagnosis, while CD20 was diffusely positive on the second biopsy from the recurrence or progression of the disease, without expression of CD79a or PAX5. Epstein-Barr encoding region (EBER) in situ hybridization was negative in all 5 cases. T-cell receptor gene analysis showed monoclonal rearrangement of ß or/and δ chains;Ig rearrangements were all polyclonal. None of the five patients were treated with rituximab, and 4 patients survived with disease and 1 patient survived without disease at the end of follow-up. Among them, the patient with mycosis fungoides at the cancerous stage has progressed rapidly and had poor quality of life. Conclusions: CD20-positive T-cell lymphoma is extremely rare. Its prognosis is closely related to the type of T-cell lymphoma, clinical stage and initial therapeutic effect. However, the expression of CD20 indicates the recurrence or progression of the disease, and the prognosis is relatively poor. When CD3 expression is absent in T-cell lymphoma, it is easy to be misdiagnosed as B-cell lymphoma. The combination of multiple immunohistochemical antibodies and molecular detection can improve the accuracy of diagnosis.

Analysis of Scores of SCL-90 of Patients with Traumatic Subdural Effusion.

ABSTRACT: Objective To investigate the factors affecting changes of Symptom Check List-90 （SCL-90） of patients with traumatic subdural effusion. Methods One hundred and forty-two cases of patients with traumatic subdural effusion from the Center of Forensic Identification, Wannan Medical College collected from 2007-2018 were tested with SCL-90. The differences between SCL-90 results and the national norm and the influences of gender, age, education level, the number of effusion sites and location on SCL-90 results were analyzed. Results The differences between the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia and psychosis factors and total mean scores in SCL-90 of traumatic subdural effusion and that of the national norm had statistical significance （P<0.05）. The differences in depression and hostility factor scores between males and females had statistical significance （P<0.05）. The differences in compulsion, anxiety and terror factor scores and total mean scores among different age groups had statistical significance （P<0.05）. The differences in hostility, paranoia and psychosis factors among patients with different degrees of education had statistical significance （P<0.05）. The differences in depression, anxiety, hostility and terror factor scores and total mean scores among single-site group, double-site group and multi-site group had statistical significance （P<0.05）. The differences in somatization, depression and anxiety factor scores and total mean scores between the right cerebral hemisphere group and the left cerebral hemisphere group and bilateral hemisphere group had statistical significance （P<0.05）. Conclusion Traumatic subdural effusion can cause certain psychological changes, which are related to the primary trauma of arachnoid tear as well as the number and location of effusion sites. Attention should be paid to the influence of the above factors during the assessment of psychological symptoms.

Down-regulation of miR-155 promotes apoptosis of nasopharyngeal carcinoma CNE-1 cells by targeting PI3K/AKT-FOXO3a signaling.

OBJECTIVE: Nasopharyngeal carcinoma is one of the common malignant tumors of the ear, nose, and throat in China. Cell apoptosis is expected to be closely related to prognosis. In recent years, with the development of non-coding RNA function research, it is proposed that miRNA plays an important role in the pathogenesis of nasopharyngeal carcinoma. This study aimed to investigate the role of miR-155 in the apoptosis of nasopharyngeal carcinoma cells. PATIENTS AND METHODS: Cell transfection was performed to knockdown or overexpress the level of miR-155 or knockdown of the level of FOXO3a. The expression of the related protein was detected by immunoblotting. The Real Time quantitative-PCR was used to detect miR-155 expression. Cell proliferation was assessed by MTT assay. The changes of cell apoptosis were observed by flow cytometry using AV-PI staining and TUNEL staining. RESULTS: The miR-155 inhibitor and mimics were successfully capable of knocking down or overexpressing miR-155 levels. After knocking down miR-155 level, cell proliferation was significantly attenuated, and apoptosis was significantly increased compared with the sham group (p < 0.05). After overexpression of miR-155, opposite results were observed. In addition, in the cells with the knockdown of miR-155 level, further knockdown of FOXO3a level significantly reduced the inhibitory effect of miR-155 on cell apoptosis compared with the control group (p < 0.05). CONCLUSIONS: In nasopharyngeal carcinoma CNE-1 cell line, miR-155 can inhibit the proliferation and promote apoptosis of nasopharyngeal carcinoma cells by targeting PI3K/AKT-FOXO3a signaling. MiR-155 may be a novel target for the treatment of nasopharyngeal carcinoma.

[Hypoxia-inducible factor-1α is involved in arsenite-induced epithelial-mesenchymal transition and malignant transformation of human liver epithelial cells via regulating Snail].

Objective: To investigate the role of hypoxia-inducible factor-1α (HIF-1α) in arsenite-induced epithelial-mesenchymal transition (EMT) and malignant transformation of human liver epithelial cells (L-02 cells). Methods: After the L-02 cells were chronic treated with 2.0 µmol/L NaAsO(2) for 0 (reference), 10, 20, or 30 passages, con siRNA or HIF-1α siRNA was transfected into arsenite-transformed L-02 (T-L-02) cells by lipofectamine(TM)2000 and were set as T-L-02+con siRNA group and T-L-02+HIF-1α siRNA group as well as L-02 group and T-L-02 group, EMT index and levels of HIF-1α were detected by western blots. The reporter assays were performed to determine if HIF-1α directly regulate Snail transcriptional activity, and soft agar colony formation and Transwell assay were used to detect the malignancy, invasion, and migration ability of cells. Results: When L-02 cells were treated for 10 generations with 2 µmol/L NaAsO(2), relative expressions of E-cadherin were gradually increased compared to control cells, while the levels of N-cadherin, Snail, and HIF-1α were gradually increased in the L-02 cells compared to control cells, showing the longer the treatment time was, the more obvious the change was (P<0.05) . Down regulating the level of HIF-1α by siNRA caused E-cadherin levels to rise compared to T-L-02 group, while the levels of N-cadherin and Snail fall back compared to T-L-02 group (P<0.05) . Double luciferase reporter gene assays showed that HIF-1α directly targeted Snail to regulate its expression. Soft agar colony formation and Transwell assays showed that the numbers of formed colonies, invasion cells, and metastasis cells of cells in T-L-02 group were all lower than those in L-02 group (P<0.05) . Conclusion: HIF-1α is involved in arsenite-induced EMT and malignant transformation of human liver epithelial cells via regulating Snail.

An experimental study on the use of icariin for improving thickness of thin endometrium.

This study aimed to investigate the effect of icariin (ICA) on thin endometrium in a rat model. To this end, 6- to 8-week-old female Sprague Dawley rats (105) were randomly divided into 7 groups: untreated, vehicle-treated (lavage with NaCl), high-dose ICA (lavage with ICA at 200 mg∙kg-1∙day-1), medium-dose ICA (lavage ICA at 100 mg∙kg-1∙day-1), low-dose ICA (lavage with ICA at 50 mg∙kg-1∙day-1), sham model (injected with NaCl at uterus horn), and sample group. To induce thin endometrium, rats of all groups (except sham-model) were injected with 95% ethanol via the uterine horn. Each group underwent its respective treatment for 3 estrous cycles, after which 5 rats from each group were sacrificed, and endometrial thickness was measured. The expression of CD31, factor VIII, vascular endothelial growth factor (VEGF), cytokeratin (CK), and vimentin were detected via immunohistochemistry. The results showed that CD31, factor VIII, and VEGF were primarily expressed in the cytoplasm of endometrial and vascular epithelial cells. No difference in the expression of these factors was detected between the ICA lavage groups and the untreated groups. However, high dose ICA-treated group exhibited significantly higher expression of CD31, factor VIII, and VEGF compared to that in the low dose and vehicle-treated groups. CK and vimentin in the endometrial tissue were significantly higher in the untreated and treatment groups compared to the vehicle-treated group. This study demonstrated that ICA increases thickness of the endometrium, and it may modulate expression of VEGF, CD31, and factor VIII.

[Diagnosis value with Xpert Mtb/RIF assay for cervical tuberculous lymphadenitis].

Objective:To evaluate the accuracy of Xpert MTB/RIF assay in the diagnosis of cervical tuberculous lymphadenitis.Method:A total of 160 patients with cervical lymph node tuberculosis confirmed by pathology in Wuhan Pulmonary Hospital between January 2015 and June 2016 were enrolled. Cervical lymph node biopsy tissue specimens from these patients were collected and tested with acid-fast bacilli smear, TB-DNA assays, culture, and Xpert Mtb/RIF, respectively. The results were analyzed using SPSS 17.0 statistical software.Result:Using pathological diagnosis as the standard, the sensitivity of acid-fast bacilli smear was 8.12%(13/160), the sensitivity of TB-DNA assay was 69.38%(111/160), the sensitivity of culture was 31.88%(51/160), and the sensitivity of Xpert Mtb/RIF was 74.38%(119/160). The detection rate of multidrug-resistant lymphoid tuberculosis using a combination of Xpert Mtb/RIF, line probe assay (LPA), and culture methods was 9.38%(15/160).Conclusion:Xpert Mtb/RIF can rapidly detect cervical lymph node tuberculosis and assess rifampicin resistance. TB-DNA assay exhibited similar sensitivity as compared to Xpert Mtb/RIF and can detect both isoniazid and rifampicin resistant genes through LPA.These two methods are more effective than the traditional culture and smear methods.

[Influence of coke oven emissions on workers' blood pressure and electrocardiographic findings].

Objective: To investigate the influence of coke oven emissions on workers' blood pressure and electrocardiographic findings, and to provide a basis for the prevention and treatment of cardiovascular diseases. Methods: The concentration of coke oven emissions at the bottom, side, and top of coke ovens was determined in a coking plant. A total of 406 coke oven workers were enrolled as exposure group and 201 office staff members were enrolled as control group. Blood pressure and electrocardiographic findings were compared between the two groups, and the multivariate logistic regression analysis was performed to analyze the influencing factors for hypertension and abnormal electrocardiographic findings. Results: The concentration of coke oven emissions was the highest at the top of coke ovens, followed by the side and bottom of coke ovens, and there was a significant difference between the exposure group and the control group (P<0.01). The exposure group had significantly higher detection rates of hypertension, abnormal electrocardiographic findings, and abnormal chest X-ray findings than the control group (P<0.05). The logistic regression analysis showed that high concentration of coke oven emission and age were risk factors for hypertension and abnormal electrocardiographic findings (P<0.05). The workers exposed to high-concentration coke oven emissions were more likely to experience hypertension and abnormal electrocardiographic findings than those exposed to low-concentration coke oven emissions (OR=1.7 and 1.9). Conclusion: Besides lung injury, coke oven emissions also have adverse effects on the cardiovascular system. Therefore, more effective measures are needed to protect the health of coke oven workers.

PI3K, AKT, and P-AKT levels in thin endometrium.

The aim of this study was to explore the expression of PI3K, AKT, and P-AKT, and to investigate the role of PI3K/AKT signaling pathway in thin endometrium. We included 40 women treated in affiliated Shenzhen Nanshan People's Hospital of Guangdong Medical University for endometrial conditions between August 2013 and January 2015, 20 with a normal endometrium, and 20 with thin endometrium. The expression of PI3K, AKT, and P-AKT was evaluated by the immunohistochemical S-P method. The expression of PI3K, AKT, and P-AKT proteins was significantly lower in the thin endometrium group than in the normal endometrium group (P < 0.05). The expression of PI3K and AKT was positively correlated with the expression of P-AKT. The expression of PI3K, AKT, and P-AKT proteins in the thin endometrium decreases during the proliferative phase, and this process could be associated with PI3K/AKT signaling.

Clinical analysis of 95 cases with ovarian pregnancy.

BACKGROUND: Ovarian pregnancy (OP) is a rare ectopic pregnancy, in which it is very difficult to achieve preoperative diagnosis. Ovarian blood supply in OP increases which will lead to intra-abdominal bleeding, hazarding women's lives. Surgical exploration should be conducted once cases of OP are suspected. OBJECTIVE: To investigate clinical characteristics, diagnosis, and therapy of OP. MATERIALS AND METHODS: A retrospective study was conducted in 95 patients with OP admitted to the present hospital from January 2005 to June 2014. RESULTS: OP accounted for 1.79% of ectopic pregnancy over the same period, of which 68.4% had a history of artificial abortion, 6.3% was treated with intrauterine contraceptive device (IUD), 87.4% had abdominal pain, 84.2% had a history of menopause, and 51.6% had vaginal bleeding. All patients had no preoperative diagnosis and underwent laparoscopic wedge resection of ovary or lesionectomy and were all were cured. CONCLUSION: Since the cause of OP is still unknown and it has no typical clinical manifestations, the present authors adopt blood P-hCG combined with B-ultrasound to improve the preoperative diagnosis. They prefer laparoscopic wedge resection of ovary or lesionectomy, which induce higher rate of intrauterine pregnancy and lower rates of ectopic pregnancy and infertility in re-pregnancy after surgery.
