Effect of Dingkundan in Adjuvant Treatment of Patients with Radiotherapy and Chemotherapy After Endometrial Carcinoma Operation / 中国实验方剂学杂志

Objective:To observe the effect of Dingkundan in adjuvant treatment of clinical symptoms， quality of life， immune function and prognosis of patients with radiotherapy and chemotherapy after endometrial carcinoma （EC） operation. Method:Patients were divided into control group （82 cases） and observation group （86 cases） according to random number table. A total of 75 patients in control group completed the study （4 patients fell off or lose visit， and 3 patients were eliminated）， while 77 patients in observation group completed the study （5 patients fell off or lose visit， and 4 patients were deleted）. After operation， patients got brachytherapy， external pelvic irradiation and chemotherapy. Patients in control group got Bazhenwan， 1 pill/time， 2 times/day， and those in observation group got Dingkundan， 7 g/time， 2 times/day. The course of treatment lasted for 4 months， and long-time follow-up data was recorded. Before treatment， and at the second and fourth month after treatment， deficiency of Qi and blood was scored. Toxic reactions after radiotherapy and chemotherapy were recorded， and incidence rate of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level were compared. And levels of T lymphocyte subsets （CD3⁺， CD4⁺， CD8⁺ and CD4⁺/CD8⁺） were detected， European collaborative quality of life Cancer Core Scale （EORTC QLQ-C30） was evaluated， and expressions of pce125 （CA125）， epididymis protein 4 （HE4）， Dickkopf-related protein-1 （DKK1）， vascular endothelial growth factor （VEGF）， matrix metalloproteinase-9 （MMP-9） and transforming growth factor-<italic>β</italic>₁ （TGF-<italic>β</italic>₁） were tested before and after treatment. The follow-up was made for every three months， and the progression （recurrence/metastasis） of patients was recorded. Result:Scores of deficiency of Qi and blood in observation group were lower than those in control group at the second and fourth week after treatment （<italic>P</italic><0.01）. Incidence rates of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level and incidence rates of bone marrow suppression， gastrointestinal toxicity， neurotoxicity were lower than those in control group （<italic>P</italic><0.05）. Five functional dimensions and overall quality of life score based on EORTC and QLQ-C30 in observation group were higher than those in control group （<italic>P</italic><0.01）， and scores of three symptom dimensions were lower than those in control group （<italic>P</italic><0.01）. Levels of CD3⁺， CD4⁺ and CD4⁺/CD8⁺ were higher than those in the control group （<italic>P</italic><0.01）， and CD8⁺ was lower than those in the control group （<italic>P</italic><0.01）. Levels of CA125， HE4， DKK1， VEGF， MMP-9 and TGF-<italic>β</italic>₁ were lower than those in the control group （<italic>P</italic><0.01）. The disease progression rate in observation group was 18.18% （14/77）， which was lower than 33.33% （25/75） in control group （<italic>χ</italic>²=4.572， <italic>P</italic><0.05）. Conclusion:In adjuvant treatment of patients with radiotherapy and chemotherapy after EC operation， Dingkundan can reduce the symptoms of Qi and blood deficiency syndrome and side effects caused by radiotherapy and chemotherapy， improve the quality of life and immune function， inhibit the expression of tumor markers and tumor growth factor， delay the progression of tumor and improve the prognosis.

Magnetic resonance spectroscopy-guided stereotactic biopsy for brain lesion / 中华外科杂志

<p><b>OBJECTIVE</b>To study the clinical value of magnetic resonance spectroscopy (MRS) image in stereotactic biopsy for brain lesion.</p><p><b>METHODS</b>From April 2008 to April 2010, 126 cases (72 male and 54 female, aged from 10 to 82 years, mean 45 years) of brain lesion which were difficult to diagnose were divided into two groups by random number table, 62 cases were executed for MRI-guided frameless stereotactic biopsy (MRI group), 64 cases were executed for MRI and MRS-guided frameless stereotactic biopsy (MRS group). Operation used MRI and Three-dimensional MRS image to locate, and used frameless CAS-R-2 robots to carry out the positioning operating.</p><p><b>RESULTS</b>No surgery-related deaths and infections. Pathological diagnosis was 106 cases of brain tumors, 6 cases of inflammatory disease, 4 cases of tumor-like demyelinating disease and multiple sclerosis, 3 cases of neurodegenerative disease, 7 cases failed to obtain positive pathological diagnosis. The total rate of positive diagnosis was 94.4%, the positive rate in MRS-guided stereotactic biopsy group was 98.4% (63/64), the positive rate of conventional MRI-guided biopsy group was 90.3% (56/62), and there was statistically significant difference between the two groups (χ(2) = 3.92, P = 0.047). Four cases presented with postoperative complications, the complication rate was 3.2% (4/126); the complications were cerebral hemorrhage associated with aphasia, epilepsy, subcutaneous hematoma, gastrointestinal bleeding, which were improved after treatment.</p><p><b>CONCLUSIONS</b>MRS-guided stereotactic biopsy group has a higher positive rate than MRI-guided stereotactic biopsy group, indicating that this method can improve the positive rate of diagnosis, and thus will help to formulate treatment plan for brain lesion.</p>
